Re: 20V silvertop potential.

a 7AGE is something that I was considering, especially as the 1800cc engine get a 100lbs weight break. I'm currious to what the real potential, I'm following the 7AGE tread and looking for some Dyno figures but I'm not finding anything concrete. Cheers, Fred As with a 4AG... all it takes is money. ...

Re: 20V silvertop potential.

OP - do you have a dyno plot?? Also you may need to change the car some as the 4AG is a taller engine then the 3T. If you make more room, you also open up the possibility of the 7AGE (7AF block, with 4AG head) As far as power potential for a silvertop... it is similar to the Blacktop, easy enough to...

On a related note. For "3rd party" cast pistons, which don't already have a coating (whatever it is that was done on OEM 10.3:1 pistons), would having the domes ceramic coated help when pushing for higher-than-stock HP? I'm guessing it at least helps with heat dispersion and so prevents h...

There isn't a horsepower limit... there is a tuning limit. There is a "flaw" with all the n/a pistons for the 4AGE... the 2nd compression ring rests on ring land that is not well supported (piston on right in photo) http://ost.ebeans.ch/albums/userpics/10005/ring_land_support_slot_vs_holes...

I guess that was my question.
