Would any one be able to identify a set of pistons by number on them please?
They are from a Cosworth
MAHLE Pistons
on the top it has : SP0,05 and 91,775
on the underside it has : MAHLE 90P44W2+

If anyone could tell me spec, low comp etc !!

Thanks

 

looks like they are standing comp 1mm oversive pistons

 

What do you mean by "standing comp"
Does this mean they are low comp ?????
Are they uprated ??????

 

as they have the writing on the piston top it means they havent been machined so should be standard 8 to 1 comp......the number is also very similiar to the standard 2wd mahles i have taken out of my cossie,but the ones you have are 1mm bigger than standard......are the gudgeon pin holes offset???? the only sure way to work it out is by measuring them though

mark

 

As said all the numbers are right for standard pistons bar the 91.775 as standard are 90.775 so urs are obviouslt 1mm oversized.

 

Do standard pistons have a large dish on the top of the pistons ?

 

Yea mate, althou depends on ur definition of large lol

 

IM building a new bottom end and these came from a 400ish bhp 3door,
I was told that they were low comp !
Are they worth much,no marks etc as i will just sell them and get propper low comps.
Can you get them machined ?

 

How much you recon they worth

 

packet of scampi fries maybe

 

Chuck in some pea nuts and we have a deal
