Order the 3658
I hope it will do the job for a 8300 RPM

ty!

 

[ibizacupra]

i wonder if you will have too much overlap on the 3658 cams, and blow thru

Main question you have to ask is WHERE do you want the power band to be?

 

[ibizacupra]

on a GT35R its kinda self explanatory tho... 4700rpm up

 

[ryan_s3]

So little duration and lift for a gt35 ! I'm so suprised you've not experienced any surge in 4th and 5th on a 1.9.Your head must be very good!

no surge experienced yet, but thats on the dyno.. on the road its spinning up on road tyres.
will see what slicks do to try and put power to the ground saturday

BIG Y car use OEM pistons and AGU ported head with gt3540 ar.82 We want to boost 1.9-2.1 bars and get 450-480whp with w/m kit

 

[ryan_s3]

The .82 housing helps with surge,as does headwork,cams,inlet manifold,throttle body. Good luck on saturday,low boost to start i reckon.

 

[h17och]

that a jp head bill?

 

[ibizacupra]

that a jp head bill?

nope

new engine will likely be JP one
this one is relatively midly ported and cleaned up thats all

stock pistons......

good luck
hope they hold out

35psi boost on my JE's, 8.5:! CR on 35R full chat to 9000rpm holds boost alll the way.

crazy-obscene for 2wd
