well when you get it in let us know if it will clear[img]i/expressions/face-icon-small-wink.gif[/img]. im thinking of doing the same thing.

 

Meaner, what's the gram weight on the HPR 14:1 piston ?

 

why cant you take your stk piston and the new 14-1 to the machine shop and get the 14-1 the same weight? they do that all the time. but i heard that the boms pistons are already as light as the stk one....???...

what does the hpr piston weight??

 

My HPR 14:1 weighed less than a used stock piston & used ron woods piston that I had at the time.

 

Might want to call Eric they have a new and improved (they are always on the cutting edge)

 

How much horsepower do you think you would gain from a 14.1 piston and a set of cams?

 

how much power from a 11.5 to a 14-1????? some one shur knows? mrhp? bom?

 

I have never just swaped a 11.5 to 14.o with out doing other mods too.

The new 14 to 1 is with in 3 grams of MrHp super light and is strong enough for NOS and durable enough for circle track. It's already clearanced for the high lift cams and big valves. If you want to lower the compession just put another base gasket on. It should have you in the 12.? to 1 range.

Looks like we have a Winner!!!!

Good info

 

Depends on what you are going to do with it. If you are just N/A with no juice then the lightest piston you can find would be the ticket.
If your going to put juice to it then you are going to have to find a piston that has a good thick crown and maybe put the ring package down a bit to shield the rings from the heat. You will loose some RPM by doing this but better that than have a "religious" piston or turn your rings inside out.
