Alright guys i just got back from the track this weekend and have some numbers to show you all to what advice you have me. Im feeling i could do alot better with some more practice but ill show my best time slip of the day. This is also with the 3.25 diff in stead of the 2.93 diff.




I ended up snapping my axle right at the joint by trying to launch harder due to having a huge wheel hop issue. What do most guys do to cure that problem?
Also that same day i had it dynoed with DynoJet and heres that print out of that...

you need more rebound control in the rear, or softer springs.

[skatebline]

Rebound control? Like what? What should I use

[nando]

your shocks are too weak to control the springs. More rebound will keep them from hopping. If they are old, replace them. Konis for example have adjustable rebound control.

Or you could go the other way with softer springs, that are easier for your shocks to control.

[skatebline]

Hmmm alright! Thanks ill try shocks. What are some real strong shocks. I'm running the bilstien sports

Totally called that, congrats! I would recommend picking up some koni's.

[skatebline]

OK sweet! thats exactly what i wanted was what someone recommend. Is there a certain koni that would be better for me or is there just one?

Single or Double adjustable?

S38B36 with a JimC chip. I've been to the track a few times this summer, this was the best slip I could find laying around my computer (left lane). I can't drag worth a damn.

single is fine, it's the rebound adjustment you want.

that's terrible.

[Raxe]

that's terrible.

I figure I should be able to get it down at least another second to the mid 13's if I launch the car, maybe more with better timing. It's really not that fast off the line though.. power doesn't start working until 3rd and 4th gear. It's a monster on the highway but almost disappointing off the light.

[Adrian_Visser]

I never thought anyone would say disappointing and s38 in the same sentance I must admit I am surprised.

[digger]

trapspeed is also slow

Ok. ill go with those and let you guys know how it works out for me. thanks
