just wondering what kinda cr your running and what boost levels with that cr.....looking to go turbo this time around with my motor, and just looking for some tips before i buy pistons.....was looking at running about 20psi at the track.....and of course a lot less on the street......pump gas on the strret is VERY important.....was thinking bout 8.5-1.....dunno for sure though.......also any fo ya know who has the best deals on pistons....JE or weisco perferred.....

 

A hair under 9:1 here... JE's, plan to run 12psi on the street when I get my turbo back...

JE sure does make a beautiful piston.

 

9.2:1 , 26 lbs of boost, 510 hsp to the wheels.

for street driving with hondata or better(speedpro, haltech, ......) i'd go 9.5:1 , 93 octane, about 14 lbs of boost. tune it 12:1 a/f ratio and run over 325 hsp to the wheels easy.

 

want to make real power - go 10:1 and get a good tuner - if not go between 9:1-9.5:1 - make sure you get a good size bore too...

 

9:5:1 with 14psi on 93 octane.

 

hey thanks all......

 

10.6:1 with 7psi on 93 octane

 

10:1 comp. @ 14psi on pump gas right now.

 

11:1 on 8lbs of boost pump gas, 12-14lbs on 110.

 

damn some of ya are runnin cr ratios i didn't think was possible for as much boost as your runnin

 

Right now....

10psi on stock internal ZC (9.5:1) daily driven

New motor....

25psi on 110, 9.5:1 overall, with a propane injection setup.

 

i run 8to1 in my b16a/drag3 at 10psi. untuned hondata. after tunning i plan for 15psi on street

 

nice to have a small bore motor (relatively) and a kickarse camber design (Bseries), no?
i could never dream of getting 11:1 on a Zcar, even NA without racegas, or getting my piston sliced.
