I have a SIR_G engine starting with 10.6cr
Head is ported and polished with .030 deck
Ported intake manifold with secondary butterfly tray removed.
DC 4-2-1 to apex-i worldsport exhaust.
Cam gears, fpr, intake
I will be running a chipped ecu and was wondering how high I can go with this or If i get some top end pieces?

 

i take my stock internal c1 to about 8400. my rev limmit is at 8600 and ive only hit it once. that was only because i thought it was at 8800 but found out its not

8400 is about as high as i see a need to go.

 

I'm thinking 8700. Anyone have a problem there?

 

did you upgrade your valve springs and rods or rod bolt if using stock rods?

 

Nope

I'm asking how high is safe on stock engine. I don't plan to run at 9k, but I would like to know if mid to high 8's are acceptable

 

with would you wanna rev that high with stock cams?there is no need to rev any higher than stock.

 

Let me explain

Valvetrain and cams cost too much for the gains. I'd rather invest in a turbo.

I'm going to do my head and intake manifold and have fun with my car. My ecu is getting a chip and I wanted to know what others have been running theres to. Only dyno charts tell me where to shift a car. Not stock fuel-cut

 

if you really wanna do it.....
my b16 i rev to 8400 only at the track, because of ls tranny
my ls/vtec is going to rev to 8300 with r cams
