They open the snout all the way up to the 102 opening and then do a real nice transition into the blower housing. As far as the blower itself. You would have to see it truthfully. There is no area left untouched in the housing area. When Keith was explaining it to me over the phone I didn't appreciate the amount of work that was going into it until I got it back. But once you do a before and after its pretty amazing. You won't be disappointed.

off topic but I don't know why the heck GM didn't put a 90mm TB on the ZL1, CTS-V or ZR1 when they had the parts already from the LS7 which has been around since 2006. GM must've known these S/C cars get modded and the 90mm TB would've been a better baseline to start with.

At what size TB do you need to port the snout? Has anyone used a 95mm TB yet?

the snout is 87mm, so with any throttle body larger than that, porting the snout would be necessary.

I though the snout was 90mm. I have 90mm no porting on the snout.

maybe the back of the 87 and 90 are the same diameter? I assumed the 90 would be larger.

If you reach your fingers in and feel the transition between the throttle body and the snout is it smooth?

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!

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?
