Dyno Results of Gen III 5.3L truck intake Radical Ported by Peak Speed Shop
Here are dyno results from Peak Speed Shop's Radical porting of a Gen III GM Truck Intake Manifold.
Stock 2001 GMC Sierra 1500, 5.3L. 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.
7 Gain in Peak RWHP
6.5 Gain in Peak RWTQ
Gains were seen throughout the power curve with points in the curve seeing as high as:
9.5 Gain in RWHP
9.5 Gain in RWTQ
Intake manifold inside before RADICAL porting. Obstructions cause poor airflow to 4 cylinders.
Intake manifold inside after RADICAL porting. Obstructions cause poor airflow to 4 cylinders.
To order, go to TRUCK - Intake Manifold : Peak Speed Shop, Boosting Horsepower...Adding Style! or call us at 719-651-1952.

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.

Some have asked about our porting process. Peak Speed Shop uses a three step process for porting intake manifolds and throttle bodies.
First, we use a steel crosscut bur for removing most of the material in key areas and to smooth transitions and ridges for better air flow.
Second, we us sanding rolls for smoothing out the area that had material removed by the crosscut bur.
Last, we using buffing pads to polish the work.
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. Second, we us sanding rolls for smoothing out the area that had material removed by the crosscut bur.

The dyno was started at a different RPM. Stuffing a rag in the intake probably wouldn't result in a 50 HP loss lol.

Who cares if it's a 6 year old post. Do they not still sell this service? Yup pretty sure they do so this post is still relevant. Just trying to understand what I'm looking at. Like I said there is clearly a huge loss down low.

There will ALWAYS be a huge loss of power when the THROTTLE ISN'T OPEN YET.
