As the topic says, who of you out there has the highest compression with forced induction either via turbo or supercharger? Post you compression ratio, boost level, and what fuel you are running. I'm sure some if you guys are over 10:1 and boosting some decent #'s.

 

You asking for built or stock motors?? obviously there area ton of gsr,type r turbos and they are over 10:1.Our h22 is 10.5:1 and made 689whp at 26psi on alcohol.

 

Very nice numbers. Basically I guess I'm just curious as to who's boosting on compression ratios higher than say stock GSR compression and what kind of boost on what fuel. I'm pondering trying something a little different from the typical 9:1 compression 12 psi kind of boost set-up and just curious as to what people have success with.

 

am running 10.2:1 on a h23 with hondata 756cc injectors see sig for numbers on 12psi

 

im runnign the 10.6:1 in my stock itr at the moment, number below from the 1st tuning session. could prob got more out of her, but gave up

Hp looks good...what's up with the low torque numbers...??

 

I think the shuttle takes us all...

the big boys run crazy compression like 11:1+ in the nitro meth cars.

The "really big boys" actually run between 5-6:1.. Anyway, I'm setting into the 10.8-11.1 range

 

what would you liek the tq to be ? this is a b18c5, we dont mkae much tq

 

thats on the huge displacement stuff though... not quite the same.
