I asked Al from GM at C5 fest in Indy and he said they had to use the 87mm because the 90mm caused the engine to get hotter faster due to the increased HP and it started pulling timing faster......he said it was a delicate balance they were trying to stay within and they had to go with the 87mm.

They do pick up a good bit of power and are cheap and easy to do.

The VMax CNC pattern ported OEM unit is good for both power and off idle response.

As for heat from the extra power, RX Super Chiller time!

In stock no wait also.

Is the throttle body as easy to swap as the LS3?

Are these ported LSA Tb's ported out to 90mm?

How much boost are people picking up with a 102mm TB and ported snout?

Faster12 · 03-08-2013, 01:22 AM

I have an even better question...what's the going rate for porting the blower?

At what boost pressue do the connecting rods bend or break?
