supercharged ls1 engine,

To be honest if mine has 155 brake at the wheels 160-180whp and a really responsive, torquey set up/curve would be fine for me

Im going to be tight and use a blue printed but otherwise standard bottom end tho, pistons will be fine, the con rods are being shot peened with all casting marks removed. But to be honest i know the con rod is the engines weak point, but at 20-21psi of boost and a 6k rev limit i can't see them breaking with me driving it, sure they will let go if its treated as a 7000 rpm car but its not and wont be..... higher rpm actually exerts higher loads on pistons and conrods than a higher boost pressure.......

Talking of nice shiny forged bits have your pistons come yet?

I was considering asking newmans to grind some custom cams to kent cvh32-33 spec, think if i got more than one done a few guys on hear would like them??????? bit of a group buy really, as the 33 seems to be a very good cam minus is wear properties and the newman profiles seem not to be spot on but with much better materials used...

Rob,
