Zach Roetker Vancouver WAclickclickGoing to go take a look at it on Saturday and was looking for additional info/details. Searched here but didn't find anythingBeen a long time since I've been on here...

Go back and look at the rules again as I think that the SP classes allow modification to the BOV (actually compressor bypass valve is a better description as it doesn't intentionally limit boost). Intake is open from the throttle body to the turbo and from the turbo to the MAS.I beleive you...

Quoting dmj: How do I eliminate or at least reduce the amount of understeer in my Gvr4?How big of a front swaybar is recommended?You may be too late as I think Whiteline quit making the GVR-4 parts, but what you need are the front Whiteline offset caster bushings, some front camber plates...

I think they are the shim style, but it has been quite a while since I've seen them. You'd have to call Quinn at CRCO to confirm.MarkQuoting deluded: are those the ones with the nut style adjuster? i started out building L-series datsun engines in the '80s. learned to HATE that style of...

Concept Racing out in Idaho Falls has been making solid lash adjusters for a long time. It looks like most of their web page is down, but contact info is still up.Concept RacingNice work guys.Mark

Way back in the dark ages I had this problem with my GVR-4. If you can find all of the old talon digest archives you could probably find my posts there.I'd start with the ECU and make sure the caps have been changed and it is in good shape.Then I'd check the ignition power transistor (just...

For those of us that are not shock engineers how about a quick primer on what the differences are between a good shock curve and a bad shock curve. The difference between regressive and digressive valving and why one is better than the other. High speed vs. low speed curves.First off, the...

Pivvay,Look at the tire and wheel chart and we'll work from there.The biggest problem I see is the 26" tire height for the slick as the stock tires are only 24" and change tall.The 8" tread width is not a problem as 8" x 25.4mm/inch = 203mm, well within what we can run. Even 9.5" width...

Install the pump per the VFAQ for "mustang walbro pump in a DSM" This will save you a lot of headaches about the O-ring leaking and if you use the insulation wrap around the pump it is pretty quiet.With that big pump you will also likely need an adjustable fuel pressure regulator. Get a good...

From my archives you can also use the following Earls fittings to block the steering rack: two each of the following: 14x1.5 to -6 AN adapters, PN 991954, and -6 AN caps.The easy way to get rid of the pump is to swap in a 4-bolt lsd rear...RRE has a VFAQ on how to weld up the trailing arm...

Check out:http://www.wtrscca.org/tech.htmfor some suspension tuning tips.Sometimes dialing out a little bit of understeer (a little bit of push is good on the street!) is just a matter of driving harder.Mark

Harry,Without taking up an apprenticeship with a NASCAR team, buy a book called "How to Make Your Car Handle" by Fred Puhn. My local Barnes and Noble usually keeps a copy on the shelf, list price is around $20, usually found for less.Quite a bit of time is spent explaining all of the...

Harry,I'd like to see the right and left sides more balanced, i.e., you should have nearly the same camber on the right as the left, both front and rear.I'd also like to see a little less toe in the rear.Where did your corner weights end up?Mark

Harry,I couldn't find anything easily. Your best bet is to call Mike at DSS.For Order & Tech Calls: (805) 541-4483 Fax Number: (805) 541-7165Sorry,Mark

Dook,Follow my original settings 1 to 1.5 degree of negative camber all 4 corners, zero toe at both ends. You shouldn't have any unusual tire wear at these settings. But, make sure you bounce the car between settings and double check them and use the TSB for the rear AWS.Harry,I'll dig...
