Yes they pretensioned the wastegates.
There were big fans blowing into the radiators (2), a fan blowing under the car, front to rear, and a big fan blowing into the engine bay. They also blew air from hoses into each intercooler. I was told by the operator that the blip at 3500 was because the boost hit 1.3 for a second then stabalized at 1.1 for the rest of the run. This was a 4th gear run.
I bought the headers because it is part of EVO's stage 4 package and Suncoast had a set in stock so I said why not.
Next a level 1 clutch.

Stock rwhp and torque?

Larry,

Do you know what your baseline dyno numbers were when the car was stock? Also, do you know what type of dyno was used? Thanks.

By the way, beautiful car!

You need to run fans backwards in to the intercooler ducts. Based on the dip in the dyno the car was heat soaked. You have to move a lot of air through the intercoolers. There is only one real way to do it right. Otherwise you get that dip. Here is a GT2 on our Dyno. Keep in mind we use a Mustang it is a conservative dyno. Our numbers are always lower.

Hey Stephen,


That dyno plot looks very familiar.

Congrats on your Stage 4. We don't see nearly enough GT2's in here. I think that a GT700 GT2 would be unreal. Have fun and be safe!

It is a 5/95 > 40/60 split or anywhere in between depending on the slippage in the rear.

Yes this is quite a coincidence! Have you done mods to the car? The stage 4 upgrade is worth every penny for the fun factor.

The Cabo is a 2002. Its the best boat I have ever fished on. Last year fishing from my place in Key West I caught a Blue marlin, a white marlin , some whahoo, tuna, sailfish, and a boat load of dolphin, 2 swordfish, and a 600 lb Mako. I hold a 100 ton Masters license but only fish for myself, I love to take people out and get them on fish. The blue last year was caught by a friend who never fished. Now he thinks that a marlin is caught every trip
Whats biting in CA? Give me a shout if ever in FL and want to fish.

Lets keep a little quiet about dealers that are mod friendly.

Shouldn't the Stage 4 be around 535-540 hp on a GT2 which has less drivetrain loss than a TT?
