Generation IV External Engine - TBSS and GM Gen IV Truck Owners... RADICAL Gains from RADICAL Ported Intake!

Peak Speed Shop now does RADICAL porting of Trailblazer SS and GM Gen IV 6.0L/6.2L Truck Intake Manifolds! Gain 15-20 rwhp!

Cory Harris from LS2PortWorks had perfected a method for completely opening up that hole deep in the plenum and removing additional barriers that restricted air flow in the TBSS and Gen IV (6.0L, 6.2L) truck manifolds. Cory's customers typically saw 15 rwhp / 15 rwtq gains and some of the 6.2L customers with headers, a significant cam and ported heads reported as high as a 20 rwhp gain.

Many of you truck guys were saddened when Cory announced he was no longer porting the truck manifolds. We are happy to announce that for the past four months we have been working with Cory to learn his techniques for porting these manifolds in order to pick up where he left off. In order to perform the porting, the top of the manifold is removed and then reattached once the porting is complete.

The cost for RADICAL porting of your manifold is just $425. We can port your throttle body at the same time for just $75 additional.

TBSS owners... we have some ported manifolds in our inventory. If you don't want your vehicle down while you wait to send your manifold back and forth, simply pay a refundable core charge to have us ship one from inventory and return yours once the job is complete.

Soon, we will also discuss the merits of 5.3L Gen III truck owners converting to the TBSS ported manifold as a lower cost alternative if they don't want to pay for the power gains of a FAST manifold. Watch for the thread!

looks good

It looks to me like a Cylinder Bore Hone was used to ream it out . . . thoughts ?

No. The top is removed and all of this is done with a die grinder and porting tools.

what gains would you see on a 4.8 silverado??

what gains would you see on a 4.8 silverado??

About 10 rwhp gain on the stock 4.8's. Gains from the ported manifold are higher on the larger engines or if your engine has been modified for more horsepower (heads, cam, etc...).

Wish you had some spare intakes for the 07.5 nbs 6.0 in the 2500hd's.

You can order a radical ported intake through us for your vehicle. The cost is $425 + $250 core charge. If you return your core the core charge is refunded.

Thought I'd pass this note along that came from a recent customer that had us Radical Port his L92 truck manifold:

“It’s installed and truck runs really well, much better on the top end than before and hasn’t been tuned yet. I can only relate to you by seat of the pants feeling. The truck now breaks the tires loose shifting from 3rd to 4th. Damp pavement, I Know, but never did this before; (we are talking 90 mph). As soon as I send Justin the log and we retune I will let you know. I am really impressed by what you have accomplished for me.”
Jack - Newport, OR

Very nice. You guys port any intake?

Yes we do.

What's the average turn-around once you receive a tbss manifold?

What's the average turn-around once you receive a tbss manifold?

Currently, it's about a week from the time we receive it to when we ship it back out. We ship FedEx Ground which takes 2-3 days to most locations. We also have some cores on hand if you don't want to wait that long. The refundable core charge is $250.

Get your L92 or TBSS manifold Radical Ported for just $200 (over half off)!

We are looking for just a few customers to work with us to provide dyno reports that we can pass along to other forum members. If you are interested, give me a call right away. The test must be a before and after test on just the Radical Ported intake manifold change.

While we've been taking orders for Radical Ported truck manifolds, we've had no takers on our offer of a $75 discount to help with dyno costs. Since we don't have a dyno in our shop, we rely on customers to send their results. The results we've stated are based on what customers reported to LS2PortWorks before we took over this porting from them. Unfortunately, we don't have access to their customers to get the actual dyno reports to post. So, we need your help.

Only a few customers will get this deal, so be the first to call!

Just received this feedback today from a recent customer.....


"Bob from Peak Speed Shop was great... he ported my FAST intake and ported my throttle body and I picked up power throughout the RPM range.... over 25 hp, and 15 ft-lbs of torque before and after on same dyno (after retune). Quick turnaround, runners were ported evenly, but not overported (still saw witness marks). All in all, fantastic and reasonably priced "
A.T. – Illinois (FAST 92 ported and Throttle Body ported– LS6)

looks like some real nice work

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.
