for an SC61 on a built H-series motor?

 

 

How much horse power you planing on making.

 

I'm still only runing a 35mm with 460whp so 40mm should be enought up to 600 i would say.

 

I think the wastegate is almost more important with a low boost big turbo setup. The reason for this being that the wastegate will have to work alot more dumping boost to maintain the lower boost level than say a high boost application where boost is seldomly dumped. Make any sense? Or I could e just a complete idiot Alot of time people get caught up in the "Well it is bigger so it MUST be better!" scenario when that isn't always true.

I'm aiming for 15-17 psi on the street and 25-30 on the track

 

40mm seems to be adequate, or just go with the 40mmhp tial one.
