make sure th there is no piston 'slap'

**bvalve** · 07-17-2012, 12:04 PM

what mean slap?

**mADmAN** · 07-17-2012, 01:19 PM

google "piston to wall slap"

but mahle and CP uses an alu grade that doesnt need as much piston to wall clearance as some brands like wiseco and ross racing which uses a diff grade of alu which requires a lil more piston to wall clearance.

theres pros and cons on each alu grade in regards to pistons... ive posted some info about it on this forum before..feel free to search my posts... cant remember where it is

so the lesser piston to wall clearance, the lesser the chances of slapping. note: "lesser" chances... not "zero" chances.

google the brand that you want to get, check alu grade from there you will get an indication

Tell us what is the application for. Drag, Time Attack, Endurance, Street, high boost, high compression? The piston should be suitable to the application. Power levels? Don't buy based on name only. Talk to your tuner. He/she will be able to advise you based on your requirement.

Forging material will depend on your application. 2618 is heavier and expand more so you will need to have more piston to wall clearence. 4032 is lighter and will expand less so you will need less clearence. Also depend on how you intend to run in the motor. Gentle run in or all out high boost at the dyno. Do your research on google and talk to your tuner. Both forgings also have different wear characteristics and it's pro and cons.

Piston slap is not a bad thing. It all depends on your piston and it's intended usage.

those was F1 piston manufacturer BTW

Both brand is good. What you should be worrying about is the size, material, design etc.

But DON'T look for piston made from 'JASMA'. Definitely not a good idea

Hehehe.. JASMA is not a brand name

its only a copycat item sold here in M'sia

Everything jasma is not good except for exhaust system brought in from japan

Actually what's the price like for both Mahle and CP anyway? A bit hard to suggest when have no idea of the price range.

Guess they wont come cheap since they made them for F1
