Yeah I ordered it brand new, it's stage 1 on the GTM site.

Off boost, lower CR pistons may feel a bit anemic by comparison, but if they are forged and lighter than OEM, they may make the engine feel more -- rather than less -- responsive, if with a bit less grunt.

Depends how much weight is saved and exactly how high in the rev range before any appreciable boost is built.

Here are some pics of the short block .

Sam

Here are some dyno graphs for car we just finished, it has the same low compression short block that Vinny will be running, This car has also our stage 1 cylinder head witch includes our upgrades valve springs and titanium retainers with a 5 angle valve job. This car was a rocket plane and simple.


The first graph is 12 PSI

Second graph is 14 PSI

Third graph is 15 PSI

Ah man, Sam stop posting this stuff...You are going to make me spend more money!

Great numbers!

Come on SAM!!! Stop, Need to build tranny first. :/

I'm really wanting one of those blocks you got vinny. I'm waiting on a TT gtm stg 2 kit to show up and the longer it takes to get here the more money I spend. I'm new to f/I and cars in general and this thread has been very helpful indeed. Makes me wonder if I should have sprung for bigger injectors myself since I went with dw 600cc Injectors but did upgrade to 355lph pump. It seems like everything is only $500 more lol
