Same as the 65mm TB, roughly 5-7whp.

 

Doing a throttle body without the intake will not gain power. Exhaust manifold if the 10.5 is already ported and the car has a SS 02 housing on it could be another 10 whp.

 

yup got the turbine side port and running the SS 02 housing.

 

Sorry Dave, but I was actually reading old threads about this just this weekend. I seem to remember reading a thread from back when you were doing some testing that you said that the TB would ad roughly 5whp, and then porting out the intake manifold would add another 5whp...then later you said that you did the combo together and gained 10whp.

Either way, it's a good combo!

 

That could be right but I remember it being the opposite. I could be wrong and am too lazy to dig it up. I don't think the TB helped without porting the intake manifold to match it, if it did it wasn't much.

 

I'm curious as to how those cams idle. Is it stock idling, near stock, or rougher? Also, are upgrading fuel injectors necessary for the setup? I ask because that setup is nearly what i want. Thanks.

 

the GSC S1 cams idle like stock and upgrade injectors is a must to achieve higher power output.

 

Oh and another thing. How is the lag? I'm not even going to pretend that I know how to tell by just looking at the dyno sheet.

 

Everyone who has installed the green has commented how "stock-like" the spool-up is.

 

Hi:

For comparison basis, what whp does a stock EVO IX make on this dyno?

Thanks

 

This is a "strong" IX.
