Yes. GM does a lot of things at a cost per gain ratio because of bean counters. We could have had 30 MPG V8 vehicles ten years ago if GM could have made money at it. GM isn't perfect, and that leaves room for the aftermarket industry...

 

Not in the mood for that arguement

Lets do the test and get er done.

Test will be done on a stock truck.

 

To be honest, I don't know what it will gain. I've had only one stock vehicle test a ported throttle body and that was an SVT Contour 2.5L 5 speed. It gained 2-3 HP/TQ across the entire RPM band, and 8-9 HP/TQ at peak. That hardly compares to what we're looking at here, which is why I jumped on your challenge. If these vehicles aren't going to show any gain, I don't want to spend $125 a month on advertising the ported throttle bodies for them, LOL!

 

wish i was closer, i would send cable shaner s2 over for shitz and giggles. i dont feel like payin shipping back and forth to see if theres any gain from it though.. i cant tell a difference with or without it, but then again, i couldnt even feel the stall and longtubes my butt meter is a pos(no pun intended)

 

I can attest to the ported TB on the SVT Contours. I'm still very active over at the Contour Enthusiast Group site. This is a fairly popular mod for the SVTs, as well as other models. I've heard nothing but good things about porting the TB from the guys on the site.

 

Dyno wont lie.

Core TB is on the way VIA USPS Priority mail.

 

This will be interesting to see....

 

 

I definitely think this will be interesting to see.....

Brian, do you have access to a flow-bench to test actual max flow throught the TB before and after porting ???

 

I am sure I could pull something together to make that happen. I am only questioning the HP gains, not the flow numbers.....Granted the two go hand in hand, the HP numbers are what counts IMO.
