Thinking about running slightly higher compression pistons. Wondering what people are running and about how much gain they are getting?

Let me know your set up because i will be trying to do cams and ITBS eventually.

 

just raising the compression is not going to yield big gains....

you are going to need quite a few supportiing mods....

cams(toda)

header (berk tech/j's racing)

exhaust(single outlet)

engine mgmt(aem)

itbs?....... maybe a filter on a stick will yield the gains you are looking for, and have better streetability

but to answer your question expect, a few extra ponies....w/ the correct tuning

also, what compression ratio are you shooting for....

are you going to run pump gas, or race?

 

S2ks are already 11.0/1

Wouldnt you have to run at least 93 if you go any higher?

I am no tuner. But this sounds right. I think some states sell 100 oct.??

 

We have 100 in cali at the shell stations. They sell it in 5 gallon tanks i believe. It's like 6-7 bucks a gallon.

 

man - our motors arent B16'S! j/k

i'd be careful - just cause its a "mod" doesnt nec. mean you'll gain anything. w/ the s2k - it may be a downgrade.

 

Some states do sell 100octane, but it's not that abundant for a daily driver.

 

the ? is what is your final goal out of the car??

 

I already run 93 octane all day long... oh yea I'm in Florida so I guess that's why.

 

Thanks for the input. Not exactly sure what I'm going to do but with all of the responses I guess what I had in mind may not be the right thing.

I'm not that interested in Drag I'm more into road/ autox. I know that suspension, brakes and all that good stuff are just as important if not more than the power. But I would like to reach around 300whp in the end. NA apparently is not the way to go about this.

 

300whp? youll need to have it stroked to a larger displacement.

I get 93. WOOT!

 

Get a supercharger and call it a day then.

Otherwise, 2.5L stroker + supporting mods. (you still won't reach 300rwhp), but get some gears to that setup and you'll be feeling like you do.

 

These are the reasons why I asked. I dont know enough. But thanks again for the responses.

 

yea

seriously? SERIOUSLY? "yea" was your entire answer? Did you sit and ponder saying that for a while?


If you are into autocross/track, your biggest time diminishing mods are coils, wheels/tires, and practice. There are guys tearing it up with stock engine, but very good suspension mods.
