i got a killer deal on a y8 head with everything except dizzy for $50 from a friend. now i know if i put a y8 head on ym b7 block instead of the z6 head, it will bump my compression up a little. but do you know how much? and do you think its anything to worry about since im boosted?

 

10.5:1.
Get a good tune.
You will love it.

well the thing is im using the emanage that came with the greddy kit. i have it on my b7 engine. if i put the y8 head on will it have to be retuned?

 

Emanage isnt a Tune.
Its basically safe to run on the greddys stock 5.5 psi.
Im sure it will be fine to run on 5.5 psi even with the 10.5:1 cr.
Even more since the bluebox/emanage make run very rich.

eh.. im running 8 psi on it since i know a bunch of people on other boards that run 10psi on it.

and yes e-manage is a tune. bluebox isnt. but you can tune emanage. software laptop...its a piggypack fuel management. no its not like hondata uberdata, but its almost just like it.

 

Did you tune your emanage though ?
I figured you didnt.
So Im probably wrong.
If so tune it, use what you have.

But go uber sooner or later.
Good luck with it man, im sure it will move.

 

but, damn you ran 13.7 in a sedan with a b7 engine/trans at only 7psi?!

im gonna be taking it to the track for the first time this weekend. i dont know if ill even hit 13's. just doesnt feel that fast..

but you did and i have a b7 engine with a z6 trans at 8psi in a hatch.


EDIT: no i didnt tune it. i can if knew how. ive got a laptop and the software.

 

It wasnt just a straight b7.
Like it matters anyway haha.
Some said I lost power the with y7 head. Ha.
Drive the **** out of it.
It will go 13's.
