New Personal Best with 1837

I got a chance to take 1837 back to the track last night. It was a packed house, which meant I only got 2 runs in. I was staged for my 3rd run, and somebody broke at about the 1/8 and they closed the track for the night. But, even with only 2 passes, I was able to run a new personal best of 13.5 @ 102, so I can't really complain.

The car was running on 93 pump at about 20psi, dropping off to 19psi at redline. Timing was set fairly conservative, peaking at 17-18*.

I definitely need some more seat time with the new clutch. I'm trying to find the sweet spot with the launch RPM, and I don't feel like I got enough passes to truly find it. I can definitely say this clutch is wayyy better than the old one. I cut my best 60' to date the very first pass. I probably would have had an even better launch if the fuckin' staging official didn't make me drive through the water box. I also need more boost. I'm running ECMlink boost control, and even with the solenoid duty cycle set at 100%, I can only get 19psi at redline. So, I need to screw with it and figure out how to get more boost up top.

My real issue is my transmission. It's just getting worn out, and shifting at high RPM is becoming a chore. So, the next step will be acquiring a decent transmission.

Overall, it was a great night. I got to meet sonyslave from T00ners and check out the bad ass twin scroll S362 setup he's running on his 1G. I ended the night with pancakes at Ihop with one of my other buddies. On the way home, we went through a sobriety checkpoint, where I met probably the only Maryland State cop that knows what a Galant VR-4 is. We chatted briefly about the car before he waived me through

By the way your boost tapering off at high rpm could be the wastegate cracking open and not holding. I had that with my internal S16, no matter what I did I couldn't go above 20psi at above 6500. Even with the wastegate disconnected.

Problem with shimming the WG is that it leads to wear on the arm bushing and increases the chances of cracking the turbine housing. It works, but Justin over on tooners found a way to use a holset actuator on the stock MHI turbos. Gives you a 18psi spring can be had for cheap.

Re: New Personal Best with 1837

You shim it under where the wastegate mounts to the compressor housing. This raises the seat and opening pressure of the wastegate by shortening the spring inside the wastegate and raising the force required to move it via Hooke's law F=-kX. It's the same as the old school mod of threading the wastegate arm and shortening the arm.

With no boost controller and 1/8" of shims (two washers) I usually see 17-18 psi on an Evo 3 16G base pressure and use a Hallman to control a steady 25 psi. This is with the larger flapper door.

I've been doing this for about 15 years on everything from Grand Nationals, MKIII Supras, 240's and DSM's and never had an issue.

Good to hear. I've never personally seen the wear I describe, but have learned it through a couple reputable turbo builders. In the past I too have threaded the rod and shortend it.

Nice thing about the holset is that they will hold back 30psi. The stock MHI will have a limit as the spring is still weak. Also it will have more throw than the shimmed/shorter MHI actuator(not a big deal as your trying to hold it closed).

I can see the bushing wear but have NO idea how this could affect the hole cracking any more. My point was that if it happened with a shimmed stock actuator it's still going to happen with a Holset or whatever regulator as force on the flapper arm is force on the flapper arm no matter how it's created.

I'm not in the elite or an E85 user so I'm not looking for more than 26ish psi out of an internally gated turbo anyway but a I could see a stronger spring being needed after that.

Also the larger flapper door gives more surface area for the turbine pressure to push on and they blow open easier than a stock flapper.

Yeah, this was actually going to be my next stop. Seems like people have had good luck with the modified Holset actuators.

I guess I could try shimming the actuator. No harm in trying the cheaper easier option first.

Re: New Personal Best with 1837

Ok, nvmd. I got a bunch of messages asking for the tune, so I'll just post it here. I dialed in the new injectors about an hour before I drove to the track. As a result, my laptop was dead by the time I got to the track, and I don't have any actual pulls from that night. Here is a 3rd gear pull from earlier that day. The only changes I've really made since this log is rounding out the timing map a bit better. Everything else is pretty much the same.

click

For anyone who my try to use this (or parts of this) in their own car, here are my recommendations:

-Tweak the timing map for max power: I have the map set at 17* from about 4500 to redline. Depending on your turbo, you'll probably want to pull some timing early to help with spool, and add some up top near redline to make a bit of extra power (which is what my current map looks like). If you just need a consistent timing value to dial in your MAF/injectors, this will probably work for you as-is. I will post my updated timing map next time I grab a log.

-Tweak the MAF: I still need to pull some fuel as shown in this log. I'm fine with running a bit on the rich side, but I'm still a few points off from having the MAF dialed in perfect. I had to make a lot of changes from the 560s to the 1050s, which took a little work.

-Adjust the BCS duty cycle: Obviously, if you're running ECMtuning boost control, you'll want to dial the duty cycle back. I'm at 100% DC throughout nearly the entire RPM range.


I also dropped my launch limit to 4500. Not sure if this helped or hurt me, as I didn't get enough passes in to really get the feel for the new clutch.

Thanks for the log. It was your timing number that got my attention. I'm pushing 24psi on 92-octane pump gas off a T3/T04 and I'm still struggling with more timing v. more boost.

Interesting. You've got almost exactly the same knock profile I have. Same counts at around the same RPM range w/ a similar throttle position.

I'm really starting to believe these cars just shake in the right way right around 3300RPM's to generate knock...

And a question: My BoostEst is generally tracking higher than my actual. I noticed your tracks lower and is more accurate through the pull. What is the method for getting the BoostEst to match what my OmniBar is showing me?

Re: New Personal Best with 1837

Dialing in your airflowperrev at idle helps with that. That's the base number link uses to calculate boostest. Now in days it's not a big deal if it's off. As long as trims, deadtime, and global fuel all seem good then it's not worth chasing trying to get it lined up.

And yes, 3k-3500rpms seem to have the biggest phantom knock. Some believe that BSE leads to this, but I've seen it on BS equipped cars too. I've had it on my cars too. My link ignores knock until around 3400.

I agree. I picked up almost 3mph in the 1/4 but only shaved just over 1/10th of a second off my ET. All I can say is my launches need work and my transmission is garbage. Eventually, I'll get both worked out. The trap speed suggests the car has the ability to run a better ET, so it's not too terribly discouraging to me. If I was able to get a few more runs in that night, I definitely think I could have made a faster pass.

Honestly, unless my car is knocking under heavy throttle, I ignore it for the most part.

The BoostEst is calculated from your airflow per rev. Since you don't have a MAF, you'd probably need to make adjustments to your VE table to dial this in better. You should see BoostEst line up with actual boost at 100% VE, or around 5500-6500 RPM for most cars. As Ryan said, I wouldn't worry too much about it if everything else is where it should be.

Re: New Personal Best with 1837

Well, took 1837 at the track again tonight. I ran a new personal best, but the car had so much more in it. My first pass was 12.8. The whether was cold (42*), which translated into the track being cold and poorly prepped. The first pass I spun all the way through first, and the car bogged as I hit second. The rest of the pass was clean, which netted a 12.8 @ 109mph. The 60' wasn't great, but wasn't horrible either considering how bad the car spun out of the hole.

I only made 1 other pass. I dropped the launch RPM to 4000 to get the car to hook in the cold. Apparently, it worked. I left the line pretty hard and felt a bang. The car then started wheel hopping pretty bad, so I let out of it and babied it back to the pits. Apparently, it's FWD now. I got it home and jacked up the front end. I can spin either front tire, and the drive shaft spins freely with the rear wheels still on the ground. I'm guessing I trashed the 3 bolt rear end. What's hilarious is it made the hour drive back from the track like nothing happened. FWD GVR-4 FTW

All else equal, a better 60' at 109 mph is good for a quicker pass, but looks like I'm done for the season. Here's a video of the run and a few pics of the day. Got to hang out with a few friends, so there's a few shots of their cars below as well.

I kinda thought I may have broken an axle off in the diff, as I've never seen a sub 400hp car clean the teeth off the ring gear. But, I wasn't sure if that may have also damaged the diff somehow. Again, I wasn't too concerned with it, since winter build plans also included dropping the rear subframe to recondition it, and upgrade to a 4 bolt rear.

Does the VCU do anything or serve any purpose when the center diff is already welded? Just curious, because my understanding is that any effects of the VCU on the driveline are negated by the welded diff.

Quoting transparentdsm:

good call, Brett i did just do a 4 bolt swap in my pumpkin. i have the rear and both axles out of the car. you can have them for shipping cost.




Yeah, I saw that thread. I'm really torn on whether or not I want to keep the 4WS and swap the 4 bolt rear into the 3 bolt pumpkin. On one hand, I'd like to keep the 4WS since it's complete, doesn't leak (yet), and functions flawlessly. I also don't want to fuck with welding the trailing arms, so there's that as well.

On the other hand, last time I was hanging out with Sal, he was telling me about a track day he was doing with his Evo. It really made me want to bring the Galant out. I can only imagine the 4WS would make that a nightmare...But I've never really pushed the car under those conditions to see how it responds/handles with the 4WS. Maybe some of you guys have tracked with 4WS? Thoughts?

Regarding the breakage, I have no idea how it happened. Traction was complete shit, and I didn't see a single car hook all day. I've launched the car way harder on warmer days, so maybe it was just a failure waiting to happen. Work has been stupid busy, so I haven't even had a chance to look at it since Sunday night to even determine what broke. The new trans has a welded diff in it as well. I'm not gonna lie, the welded diff sucks complete ball sack for anything but straight track racing. But, since that's mostly what I use the car for, it makes it hard to get rid of.

Re: New Personal Best with 1837

Well, I know I said I was done for the season, but I lied. Breaking an axle on the second pass last time I was at the track kept me from tapping into the car's full potential, which really sucked. Not only that, but I really wanted to push the car on the bastard 20G just to see what it was capable of, especially on E85. So, I figured what the hell, I'd hit the track up one last time before the snow files.

So, once again I drove the shit box an hour to Capitol to make a few passes. The high temperature was only 45* today, so I wasn't incredibly hopeful that I'd get out of the hole on a cold ass track. Turns out, the track prep guys were on their A game today, and that shit was sticky as fuck. Of the half dozen times I've been there, the track has never been prepped that good, IMO. I was cutting 1.7 60's all day. First, let me say, I'm far from a pro driver. And second, I'm on Dunlop Direzza DZ101's at ~30psi...Not exactly a racecar recipe for good launches. The track was honestly just prepped really damn good. With consistent 1.7 60' foot times, the car ran 12.2's all day. The best pass was 12.1 @ 117.

Boost was peaking at around 28psi dropping to 26 at redline. Timing was still super conservative at 17* peak. There was plenty of room for more boost and timing, but before I got a chance to mess with the tune the car broke.

Somehow, 2 blades broke off of my brand new SPAL fan, which knocked a hole in the radiator. The car started pissing water everywhere, so I had to call it quits. I had one of my buddies grab some gas tank repair epoxy from the nearby parts store, and patched it up so I could limp the car an hour home. The is the second time I've had a SPAL fan that blades busted off of. It happened at the track BOTH times too, so IDK WTF is going on with that. It sucks, because the radiator and fan were damn near brand new.

Pretty much no fucks given that the car is broke, though. A new personal best isn't a bad way to end the season, broken car or not. I honestly think the car has a 11 second pass in it as it's current configured. With a better trans, I know it's an 11 second car as is. But, with plans to have the new 68HTA in new year, I'm not sure if I'll get another opportunity to push the car like it sits right now. I guess we'll see what next year has in store.

Per the usual, here's a photo dump of the day and some video of the 12.2 pass. There are a few shots of my buddy Dan's Talon and MK3 Supra as well.

^ never thought i'd see the day people start recommending Mishimoto over SPAL...
I think Mishi has upped their game in recent years, and not just in a marketing capacity. If it does prove to just be a defective fan, then sure, give one of those a shot. I might chalk one up to an anomaly or defective, but 2 SPALs failed now? Gotta wonder if something else is afoot. Brett i'm sure you'll figure it out.

Nice runs, BTW. Glad to see the car finally coming into its own!!

Re: New Personal Best with 1837

That's an old picture of an old setup. This was the current fan setup:


There's a gasket on the perimeter of each fan. There's nearly a 1/4 of clearance between the blades and the closest part of the radiator. Apparently, that wasn't enough. To be clear, I know it's not the fault of the fan. It's something I'm doing. I'm guessing the plastic ties that push through the radiator aren't cutting it at 100+ mph, seeing as this only happens when I'm at the track.

No biggie, it's a cheap radiator and the fan isn't horribly expensive either. It just sucks I have to replace them both seeing as they were both fairly new. Gotta pay to play I guess.

Re: New Personal Best with 1837

Got to take the car out to the track and make some passes last Friday. I didn't run as fast as I would have liked to, but it was nice to make some shakedown passes on the new setup. I mainly struggled with traction and shifts, both of which hurt on the slips. Before Friday, I probably launched the car one other time on the new turbo/motor, and it showed. I couldn't cut a decent 60' all night. With a few adjustments, I'll get back out and make some quicker passes when it cools off here in the Fall.

Although I didn't achieve any new personal bests, the car ran rock solid all night. I hot lapped the first two passes to beat staging traffic, and the car didn't give a single fuck. Temps stayed in check, and the motor runs awesome. Best of all, no breakages...Which is more than I can say for a bunch of other people at the track that day. I think I spent half the night with my thumb in my ass waiting for the track crew to clean up oil and shit from breakages.

Luckily, a few friends showed, so there was somebody to BS with while we waited. I got a few pics with Jason's MKIV Supra (runs 9's on a street tire) and my buddy Dan's 1GA Talon.

It sucks running 12.1, doesn't it? I mean, you feel like 11's are just so close... then you go out and run again and don't do as well.
At least, that's exactly what happened with my car. Seems the same here.
Maybe i'll get it out again this year, but I doubt it. Until i put new tires on it, i don't think i'm going to beat my 12.1 ET or my 118mph trap. Not on 92 octane pump gas alone, anyway.

Re: New Personal Best with 1837

Curse of the 12's...

I took the Galant out to Capitol Raceway once again trying to break the 11 second barrier on the 68HTA. And once again, couldn't quite pull it off. I was robbed by 3 hundredths of a second.

FML

Overall the car ran awesome, but my launches are what ended up being the deal breaker. If I could have cut any time off at the line, I would have had it. I've cut low 1.7s in the Galant before, but out of 4 passes, I just couldn't ace the dig. Traction was decent, but the water box was spread across the line and I wasn't able to go around it, which didn't help. Better tires, lower tire pressure, NLTS, suspension tweaks...All changes I could have probably made to shave some time, but didn't. My crappy ass transmission didn't help my times either, but the Shep box in the garage should fix that.

At the end of the day, the Galant is just a street car I take to the track for fun. And it was a ton of fun. Best of all, I drove there, made four 12 second passes, and drove home without any issues. That's always a win.

At this point, I'm pretty sure this is the end of the road for the 68HTA, as I'm satisfied with how far I've pushed this turbo. I wanted to see what it's capable of, and I think I'm pretty content with my answer. On a better day (and with a better driver), I think it could have pushed the Galant into the 11s. I also think it's good for another 20-30 hp on the dyno with some tweaks. But, I won't be the one to see the any of that unexploited potential, if it exists.

So, some decent changes in store for the Galant in the near future. I'll be replacing the 68HTA with a FP3052 ball bearing setup, and adding all the good stuff that goes with it. I'm also FINALLY going to install a decent transmission in the car, which its never had since I've owned it. All of which mods should make for a quicker, more powerful, and better rounded setup.

1837 may not have dipped into the 11s last night, but eventually she'll get there. I set a new personal best for trap speed and ET in the car, so I can't be too upset.

Re: New Personal Best with 1837

I was out at the track again a few weeks ago. I wanted to make some shakedown passes on the new turbo setup to try and get the car dialed in. It was hot as fuck, and I wasn't terribly excited about making passes in the heat.





The first pass I turned down the boost a bit and came out of the hole nice and easy just to get some decent log data of a 1-4 WOT pull. The logs showed the car running great, even with 130+ IATs toward the end of the run.

Once I was confident the car was running well, I turned the boost back up, and did my best to get out of the hole. I hot lapped back to the staging lanes after the 1st pass while the crowd was thin, and per the usual, the track staff dragged the water box across the entire staging lane, which left me with greasy rubber on the line. I cut a decent 60', and made a [email protected] pass. I had the redline set at 8.75k, and the trans refused to shift from 2-3 and 3-4 until the revs dropped down, which killed my ET. I'll be addressing the shifting issue in the coming weeks with a QM twin. The logs showed pretty hot IATs once again, but otherwise the car was running solid.





I hot lapped back to the staging lanes again to get a 3rd pass in. I didn't change change anything from the second pass, and hoped to concentrate on my shifts to try and improve the ET. I never got that far. I launched the car, and immediately got a ton of vibration in the drivetrain. I knew I chunked something, so limped it down the 1/4 and pulled into the pits.

Once in the pits, I got a look under the car and saw the slip yoke for the DSS driveshaft hanging about 2" too far out of the rear of the transfer case. I tried to seat it back onto the input shaft with no luck. I have some ideas as to what caused the failure, which I'll share at a later time. But, basically the DSS slip yoke seems like it isn't the greatest, and is prone to failure.






I swapped in my stock driveshaft for the time being to get the car back up and running. I've been working with customer service at DSS for the past few weeks to resolve the issue I'm having with the DSS driveshaft. Once I have a resolution I'll outline the entire debacle.





Once again, 11s have eluded me.

Re: New Personal Best with 1837

I decided to take the Galant out to Race Legal in San Diego to test out the new clutch. Finding a place to do test launches in SoCal isn't easy or convenient like it was while I was in Maryland. I wasn't expecting to set any record times, since the 1/8 mile "track" is just a strip parking lot they section off to make runs on. As expected, zero traction out of the hole, but it was definitely fun making passes and hanging out.

I dragged David (ApexHunter) along with me, and also got to meet Richard (faqinshiet) and check out his GGSX. There were some local DSM guys there we got to chat with as well, so all in all, it was a good time.
