Here are Dyno Results from TBSS Intake Manifold Radically Ported + Throttle Body Ported by Peak Speed Shop
Dyno-tune results provided by MadTunes Racing - Oak Grove, LA

"As far as performance, it is definitely a noticable difference. It should easily pick up .2 in the 1/4 and in my opinion is worth the money! " Adam - West Monroe, LA

Stock 2006 Trailblazer SS with cat back exhaust. A tune was done prior to the "before" results to factor out the effects of just tuning the stock setup. Dyno was before/after test on ported intake and throttle body only.
9.12 Gain in Peak RWHP
11.25 Gain in Peak RWTQ

Gains were seen throughout the power curve with points in the curve seeing as high as:
13 Gain in RWHP
20 Gain in RWTQ



Note: Vehicles with head and cam mods should see even better results.

Not bad gains for just some porting of a stock intake.

 

....and throttle body.

 

^ true. Also I find it very hard to believe that an average of ~10 hp gain will pick up .2 on a vehicle as heavy as a tbss, I think it'd be worth under a tenth with just the porting.

 

We see the dyno chart image was showing up, so we updated the image link so you can see it.

For those who have been asking, we are now able to Radical port the GenIII GM Truck intakes. Here is a link to a before/after dyno that was done on a stock 2001 GMC Sierra 1500 with a 5.3L engine.

Peak Speed Shop Porting Process

Some have asked about our porting process. Peak Speed Shop uses a three step process for porting intake manifolds and throttle bodies.
Unlike some businesses that do porting on the side, porting intake manifolds and throttle bodies is our primary business. We have earned a good reputation for quality work and service at competitive prices.

Go to our website at http://www.peakspeedshop.com/ for more information, or call us at 719-651-1952.

That is some radical porting on the manifold. Wonder why all that material is there from the factory.
