Does anyone know how high of compression you can run and still run 93 octane pump gas?

 

We really need a 99th thread asking this question?

Try the search button at the top.

 

X2 it works pretty well

 

If tuned properly, around 12.5-13:1

 

id go 12-12.5 just to be safe 13.1 can be tunned but sometimes you can make less compression and more horse power im running 12.3 seems to work good for me.

 

alright thanks im thinking about building a stroker out of my gsr this winter and looking to get as much power as posible

 

Cool, a stock sleeve stroker?

 

yea.. or do you need to sleeve them?

 

I think 12-1 will be perfectly fine for a street car on pump. much more than that and you can brag that you are "runnin 13-1" but you'll most likely have to pull alot of ignition timing to get away with it. 12-1 and keep some reasonable ignition timing in it.

 

High CR doesn't automatically = Power
What stroker kit are you planning on doing? LS/B20 crank and rod combo? What cams, intake manifold, header, etc?

 

Research how increasing stroke effects sidewall pressure, then get back to me.

 

I run 13.5:1 cr on 91 octane with 28* max timining at WOT, but I dear not enter vtec without race gas.

 

im not sure yet i was thinking of going with the egale 85x95 but im not sure if i want to stroke it that far im trying to ask around and get some oppinions on what is best. but im going to run skunk2 pro cams and intake not sure on the header yet i just have a dc sport right now but plan on upgrading
