Re: Cam only on A4 (sbkim)

I think you meant to say, legend?

There is a difference between the tranny on a Z06 that effectively turn the 3.42's into approx. 3.73's.

I am sure that someone else will chime in if I am incorrect. :cheers:

Thanks

The way I understand it is the Z06 rear has some hardening thing done to it. Someone described as dimpling?

Parts in the Z06 rear are shot peened to make the stronger.

Re: Cam only on A4 (REDGAR)

Race weight of 3540 !! :crazy:

Your 385 rwhp and 115mph just didn't add-up till now. Get that thing on a diet.

I trap the same now with the longtubes as I did before them. Seems my valve springs are shot now (only 10000 miles on them).

After my last dyno I only made about 2 more rwhp -peak- but lost from 5200 and up as much as 20 rwhp.

So a cam is on its way with new valve-train too.

I wont be happy unless it traps 116 and 117+ with skinnys and good D/A.

I'll wait to post my ET predictions, dont wont you guys to think I am crazy. :jester

Re: Cam only on A4 (RWhite)

So you saying that 115 for 385 rwhp is too low?

I thought it was kind of high for a cam only car

Re: Cam only on A4 (REDGAR)

I trap 112mph with a 32?rwhp, and my last dyno read 318 with valve float above 5200 and still trapped at 111.5+mph

So are you saying that with 60+ rwhp I will only gain 3 mph ?

There are many cam only F-bodys that trap 117mph.
And to say cam only is misleading, I mean cam + bolt-ons only.

And if your car loss say, 200 pounds then you would have a 117mph. That is what I am using as a baseline.

BTW my cars is 3290 with driver. Nothing removed, no light rims.
