CGT vs. Stage 4 TT

How much faster is a CGT? Has any mag or other people do a comparison?

the winning shootout car had 830 hp (AT THE WHEELS! and 900+ at the crank) and pulled about the same 1/4 mile time as a CGT despite 50% more power. so in addition to getting spanked in the corners by the 1.3+ G CGT vs. the sub 1 G TT, and stopping zip codes fasters owing to appreciably lower weight, the CGT should put a spanking on a Stage 4 in a straight line. and of course, one is designed to run 4 years and 50k miles without much trouble while the durability of the other is anyone's guess.

No they sure didn't. I think they figured their target market didn't want to find itself in the same position as some of the tuned car owners:

Excellence on the 900 hp TT run:

"The clutch was in, but now the engine was throwing a fit. The crew got it to the line, but the 996 faltered badly on its first run. When Law stopped just past the tree, everyone thought the motor was toast. He got it restarted and completed his run, but the car sounded like it was fouling plugs. Or coil-on-plugs.

Back on jackstands and with the help of GIAC, Evolution gave it one more try."

Wasn't Fred's TT a Stage 4 and didn't he have similar difficulties fielding a properly running car for either the dyno on 1/4 mile in one of these things?

and then there was this from the same shootout article:

"The FVD car had no squeaks, rattles, or fault codes, which were all issues that afflicted several of the other rides here. "

In all fairness the clutch issue was with Sachs. That particular piece I have had fail 4 times here in the shop. Even when we send them out to be modified. So in all fairness that was an issue with Sachs, not the car. Also keep in mind the running issue was a last minute issue that was induced by us getting the motor in the day we left for Las Vegas. Todd's wife had a baby and they needed help finishing everything. Stu's car was done, but when I arrived early that week the motor wasn't even completed. We slipped it in Mon, tuned it then all headed up to Vegas.

Also FWIW my personal car had zero issues. Regardless of what the article said my car did not have any lights on other than what was caused because of the dyno.

Lastly the CGT is a Le Man inspired car. the TT is great, but did not come from that frame of mind.

from what I've seen, I think it will be very close in a straight line race. a 1/4 mile ET is only representative of a) driver skill, b) track prep and DA and c) traction.

The trap speed is what tells of who would do better in a street race. They both trap in the high 120/low 130 range in the 1/4. With that said it should be a close race with the advantage to the CGT.

Complete anilation of the F430 in every comparison save for price. People have to get their heads out of magazines and their butts into driver seats to see just how major the diff is. The 430 doesn't provide that much improvement over the 360 Stradale, and the Stradale is just brutalized by the CGT in every performance aspect.

FWIW, I don't mean to step on the toes of the tuners around here. That said, a "modified" TT just isn't much competition for a CGT - especially in an all round performance contest which also places any emphasis on reliability.

Ben,
No toes stepped on here. I just wanted to make sure that everyone knew what the cause was. Besides, I am not just a tuner

Since when does a stage IV trap 130? It's going to take one of the upper end stages to get close to the carrera GT and a turbo will never get close around the turns (well CJV might differ, but who cares, 99% of the time the carrera GT is superior)

..Hey Stephen,
out of curiosity, how many or what % of customers do you get at IA from, say California?
I've seen your announcement of IA's Open House here, and over on Rennlist, and I've noticed your ads in magazines lately.

Just curious.

btw: it's 2.12pm on Dec 31st right now, the two posts before mine say that it's 12.39am on Jan 2nd, 2005.
So, how WAS the New Year's after all???

I know of a cobra that traps high 120's that raced a stage 4 turbo and lost. So my only assumption is that the S IV runs high 120's, low 130's.

Not real scientific
