alright, i have been thinking about installing a high compression piston while i am having my head work done and i was wondering what would be the best compression piston for straight drag racing since that is pretty much all i will be doin....my goal is to be superfast but yet stock bore.....do you see where im going with this????? any help will be appreciated

 

I think you had right in your signature; 14:1. Overall power is what you want - but there will be gains over 11.5:1 through the entire RPM range. My understanding is that race motors of all kind are high compression.

However, if you are running NOS, this might not be the best choice. Lower compression pistons work better with NOS. Im not the expert on NOS, but that is what a few race mechanics have told me.

 

yeah i was thinkin 14:1,but i will be naturally aspirated also

 

isn't there a 16:1 in the works?

 

Man, 13-14:1+ compression has gotta be hard on the rest of the motor..... Around here 12.5:1 compression is like "HOLY $HIT, THAT'S CRAZY!!!"

 

14:1 is no problem in the DS - I've been running it for about 6 months. Its nice. I also run the 13:1 piston in my 400EX - also very nice - not hard on anything - its all good!

 

ok thanks for all the help guys now where can i order it from lol......

 

and also will it fit in stock bore bike without any modifacations

 

Correct!

 

The 14:1 is the way to go on Alcohol. I really like mine! I have abused mine on TT and circle track with no problems, and yes it drops right in the stock cylinder without any mods.
