RIVA'S high comp pistons
Has anyone tryed the riva's high comp pistons?
Just wondering the + and the - of them on a stage1 + sc wheel rxp for example
There are huge gains of power?
What about the fuel requirments?
its a bolt on item or needs machine work on the block, head, valves etc...
Also wondering what to expect if install them on a bone stock gtx 185 exept from the reliability (i think there are no forged pistons on the 185's)

I think that you playing with the fire of adding a big charger on the 185's due to the non strong pistons

the higher comp.ratio pistons will require the use of race fuel on higher boost engines, or at least a mix
Sounds expensive to me
