if i net 330 to 350 hp with a lovefab gt1 kit on stock 11 to 1 compression at 7 psi, what numbers can i expect with 9 to 1 compression at the same boost?

 

I think most of us would recommend running a thicker head gasket at anything above 7-8 psi...

just a thought...

 

Around 15hp less

 

i wasnt sayin nething about raising boost, 15 less ok thanks

 

really only that much? I would have thought it more. 15hp is well worth the longevity the decreased compression will provide.

 

9 to 1 compression plus the forged internals, ill motor

 

For every point drop in compression, you will average a loss of around 30 whp at the same psi of boost.
So, if you are making 350 whp on 7 psi with 11:1 compression, you'll drop to around 290 whp on 7 psi with 9:1 compression.
I am going to just be adding headstuds and leaving the compression at 11:1 and running around 10 psi on pump gas. The engine will be just fine there with a good tune.
Remember, 11:1 compression on 10psi is about the same as 9:1 compression on 16 psi and you will net roughly the same peak whp. It's just that doing it on 10 psi and 11:1 compression will yield higher torque down low.

 

11 to 1 compression at 10 psi wont hurt the motor?

 

with a good tune you should be fine.. for awhile at least

 

yea for a while, i dont have the luxury of being able to blow my motor, i need safe turboness, even though that doesnt exist
