03 Cobra vs. New C5 Vette - You wouldn't believe the result

Saturday we dyno'd a Turbo Buick GN and it posted some freakin' awsome numbers. The HP was in the 390's and TQ was an earth shattering 455. I've always been a fan of them, and would never talk bad about one, especially if there was one in the general area.

That car was running more boost than stock. I have seen an 87 GN dyno 1,098 rwhp with a Thumper T-100 , but it was a 130K drag car. I made 388 rwhp & 427 rwtq at Atco at an NMRA event in 95 degree heat with less than 6 psi, stock electronics & fuel system. Turbocharged V8s make some crazy numbers also, but usually with alot less boost. Hell, I'm a big fan of any turbo car.

20lbsofboost is your car completely stock except fpr maybe a K&N air filter. I think not! Put 20lbs of boost on the mustang and all you will see is tail lights.

Huh?

Um, my sig has the mods for all my cars which is a whopping 3 on my Pontiac (and no K&N...the airbox is all stock too). This spring I'll at least be mid (if not low) 12's with a few hundred $ and NO NAWZ

Now disbelievers are quick to point out that since I have my boost turned up it's no longer stock. Perhaps, but such a narrow interpretation of "stock" is shallow minded. If you change your battery or tires (which may increase performance) that deviates from a stock package as well. My car came factory original with an adjustable wastegate rod to raise or lower the boost at will, not my fault the engineers were thinking ahead. No different than the factory transmission in these cars. There's a "TV" cable from the throttle body that leads to the tranny. It's made to be adjusted and changes the fluid pressue and shift points. Adjusting this FEATURE doesn't deviate from a stock car. That's the way the car was manufactured, and for a reason. Adhering to the factory adjustments during the life of a car is rediculous.

What kind of numbers are the 03 Cobra's posting?

Dyno numbers are typically 355 - 370 rwhp. (Ford underrated the SAE hp of 390).

Most magazines get a stock '03 Cobra to run high 12s @ 110. MM&FF got theirs to run about 12.4 / 12.5 in stock trim.

That's what is cool about the 03' Cobra's: Very fast off the showroom floor and even faster with some sticky tires, pulley and exhaust. I'm thinking high 11's @ 115+ with these mods. Cool.

Damn! That's a tough act to follow off the showroom floor. What's one costing new?

MSRP on the Cobra coupe is roughly $34,800. The convertible goes for $38,800.

It's a lot for a Mustang, but it's faster and cheaper than a new Vette, and will nip at the heels of a Z06. Mad power can be had through just a pulley, chip and exhaust.

Damn, that's crazy! What's taken so long and what is GM possibly going to do to level the field???

I hope GM does something soon. I'm a big Blue Oval fan, but I firmly believe that competition sharpens the breed.

Let the ponycar wars return!!!

My bad...TTA's have some impressive features and power for a V6. I did not know you could turn the turbo up to 20lbs. Did any other GM products have those two features. I'm not trying to flame you, honestly, but I did read about the TTA and there was nothing on adjustable waste gates and gear settings. Is there any web pages that you know of that I can look at to read up on them. One of my favorite cars besides Mustangs is the GTA. Inspite of my attitude I do like all cars that are fast. I even respect imports that are not all show and no go.

Thought id share what i saw an 03 cobra run, i ran him at the track, on stock factory tires it went 12.8 @ 112, his 60' was 2.1, mine a 1.85, i killed him outta the hole of course, he reeled me in after the 1/8th, if he was on the e.t. streets i was....... 12.40's i bet.

Most comprensive site is http://www.89tta.com. I personally can't attest to all the cars coming with the adjustable wastegate since I didn't buy my car new, but guys on my email list who purchased them brand new in 1989 say their's came with them while others did not. We surmise PAS put them on some cars and not others, why?...who knows. These cars have an interesting engineering history. As far as the TV cable you can get tech info on what it does and how it works here: http://www.gnttype.org/techarea/tran...n/tvcable.html

Hope that helps!

On a side note I love this state:
