where was your cam timing set? my zex cam pulls much stronger up top than my stock cam on my y8.

 

hey we are running like the same setup except mine is all stock bottom end.. i have a thick headgasket to lower my compression though. i put down 252 and 195 you do have a lot more tq then me though.. how does the came sound?

 

oh i was only on 10psi though..

Tuning, tuning, tuning. Play with your cam timing some.

I agree. Best band for the buck! Sounds like you needed more tuning or fix the cam timing.

 

I have an almost identical set up and my peak tq was at 7 grand and peak power was at my redline of 7500rpm with the Zex cam. Only difference is I run 9.0:1 compression pistions and the same boost level. Something seems to be off here. Your Tq drops off very fast.

 

I went with a Delta 272 cam, its a high lift n/a cam but **** is it ever amazing

Was much better up top then my Zex cam, I sold my used zex cam for like $150 and bought the new regrind 272 for $130 shipped

Getting a 700rpm idle was a pain though, little lumpy

 

I use to have a JG turbo cam in my a6, I don't remember if I ever had a turbo on with it though haha. God I wish I kept that cam

 

How do your Zex race cams idle?

Just wondering.

I have the same one.

 

Mine idles like stock.

Fix your boost first, looks like its falling off in the higher rpms. With that turbo it should not be doing that. Your HP takes a **** after like 6k. (thats highly attributing to your torque loss)

 

What was your A/F from 6000 to 8000?

I'm running a JG 85vt35 cam running straight up it makes great torque to 7500rpm then slopes off slowly. The idle is a little rough though.

 

The car idles good, just like stock isnt fully tuned, I have new i/c. IM and methanol injection kit to try out. The tuner wanted more time but I was about to be deployed so I couldnt leave my car, trying to figure out the avc-r too. In a month or so I will have new #'s with a lot more boost

 

Still have to set the gear dependatn boost on the acv-r anybody now how to figure out tire OD?

 

ZEX = COMP = Quicktyme = 59300

mine idles like stock
my peak torque was @ 5300 and my peak HP was at 7k

 

You guys think maybe my boost duty is set to high seen boos to quickly&gt;?

Are you sure you fixed that? Do you have a mechanical guage to confirm?

 

yes I do it was hitting boost cut
