Piston and gear ratios
Turbo Mini Forums

Hello all,

Couple of questions for you all.

Can someone advise of a +0.060' forced induction piston with an 18cc dish (or equivilent) for an engine of 200+ hp. Vizard recommends not to use Omega cast in engines exceeding 170hp (shot peened radius helps), however I think the 18cc dish only exists for +0.020.

Also, is there information/ software tool available that can tell me max speed per gear based on rev limit, wheel size gear, diff ratios etc.

I have tried searching but with no success.

Thanks in advance!

Chris.

Accralite pistons would suit - http://www.avonbar.com/product/?pid=5759

In the 13's at last!.. Just

Thanks for the info.

Sorry forgot to mention, will be utilising standard stroke.

I dont think they have +0.060'. They have 1310, and 1380 but not 1330. Thing is, why do they refer to the pistons in cc rather than bore size???

mr t , have a look for 'gearcalc'on google .
