getting (close) to 400hp. what's next?

[EfiniX]

I'm around 315 right now with the following

Rebuilt .1 overbore w/2g rods and pistons and 264/264 cams
20g @20psi
2g manifold w/3" fijitsubo all the way back
1000cc injectors
dsmlink v3
255 walbro
K&N element w/2g MAF & intake
Stock intake manifold
ETS FMIC

That's the cliff notes. Other little odds and ends. Im installing a wideband at the end of the month, so I'm sure I'll get a bit more power out of my tuning adjustments. I think I'll also invest in a FPR.

So, what's next if I want to stay away from meth and E85?

 

[turbowop]

Moar boost.

 

[prove_it]

5 more psi and bigger cams /ubbthreads/images/graemlins/grin.gif

 

[prove_it]

FP exhaust manifold. I'm not sure if an intake manifold would help that much or not.

 

[turbowop]

May as well go speed density as well. Besides allowing less restriction for the turbo intake, you'll be able to log boost and IAT's.

 

[prove_it]

Forgot to ask....

What do you have for an o2 housing?

 

[turbowop]

FP exhaust manifolds look nice, but I'm not so sure he'd see a power increase with one. That's why I haven't put one on my car. I've seen mixed reviews on whether or not they make power, and I like being able to retain my OE manifold heatshield. Even on sale, you gotta pay roughly $200 shipped for the mani and then buy a $100 blanket for it which looks weird...or spend money on a good quality coating. Either way, I think those dollars could be better spent elsewhere for now.

Wanna make easy power? Simple meth kit, boost, and timing.

Wop, you just want to see the whole world on meth. You meth head. /ubbthreads/images/graemlins/rofl.gif

Whats wrong with meth?

 

[prove_it]

Nothing, I was making a pun since meth drug use is huge around here....

Meth in lungs=bad
Meth in intake=good

 

[MellowVR4]

Get that crystal in yoo system lol just kidding, im sure everyone know what meth for humans does to them lol Meth for cars, now thats a different story /ubbthreads/images/graemlins/devil.gif

 

[EfiniX]

What I'm gathering is that at this point, it's a bunch of little things to get me to 400 rather then one or two big things?

 

[EfiniX]

and can I run 25psi on 93? What are my considerations? I imagine air and fuel. Will my 1000cc injectors do it?

 

[turbowop]

When I'm not spraying meth. I run 25psi through my FP3052 using 950's, so yes, your 1000's will work. And the highest octane I have here is 92.

 

[prove_it]

You'll be fine with 25psi. That should give you the biggest jump towards the 400 mark. You can run any octane you want as long as you pull timing. 93 would be your minimum I'd recommend. You need all the timing to can get without knock. I'd bump up boost to 25 and get a solid tune done. Might be able to push up to 28, pending on how solid the engine is.

Also is your driveline in good shape? Bad or old U-joints can suck up power trying to make it to the wheels, maybe not much but still worth checking.

 

[5OF2k]

Moar boost and timing, you should be able to hit 400 NP. Speed density or a MAFT will make a big difference too.

[MellowVR4]

Thats what im tryina get at

My setup plan for this goal is:
slowboy g60 20+psi
meth kit
possibly bigger injectors then 750cc, which is what i have now
external WG
Tune

Along with my other mods that i have.

 

[turbofonz]

My personal choice would be:

Speed density, and retune with more boost, and adjust timing accordingly. I'd shoot for 25-28psi. A log will tell a lot about where power can be had.

FP manifolds are great, I saw decent gains going from a 2g manifold to a FP race.

But otherwise, 272's might help a bit, 264's are fun though. I don't know enough about 20g's efficiency, but I wouldn't be buying many other parts. I think the car should be able to do upper 300's as it sits, and speed density just makes the car better IMO lol. Wideband for sure.

Meth I'm not a fan of, e85 would really wake the car up, but you wouldn't be able to run it super hard on those 1000's. but on pump, for sure, you can make more power easily with more boost and tuning.

 

[turbowop]

What kind of gains did you see with the FP manifold, Fonz?
