Puzzling meltdown at the dragstrip...

[tvurt]

Make sure you look down the road a bit and get a clutch that can hold whatever power you plan to make. I got receipts for 2 clutches within a year, when i bought my car. First clutch was a stage 3 that did not hold the new power. You are welcome to try the feel of my stage 4 so you know what you are getting into. Tom

Hey Tom,
How much HP are you running... I would defintely like to check out your setup before i spend 3-4 K.. who does the work on your car???

Looking at the receipts from the PO, EPL put in the last clutch. It's a sachs stage 4 with clutchmasters modification. I am guessing that the new clutch went in after the new injectors, fueling, and tune at EPL.

Its a good question how much power this car is making. The last dyno I saw on this car put it at 580rwhp/600rwtq. That was before a new tune and fuel system upgrade.

I have detuned the car a bit, and am holding the boost between .95 and 1.08 on 94 pump. I am pretty sure the car would be close to 700 hp on a high octane and 1.3-1.4 bar, but I can't find a reliable VP fuel distributer in Akron.

Oh and I do the work on my car, but if anyone in the area was to work on it, I think that Tym Switzer would be my choice. Seems to have a good rep on here.

nice.... I have mentioned this before... but 996TT's are not drag cars. Will they do it? Sure....

for UNDER $25K you can build a Mustang Capri with a SB Ford and a TT setup that will make over 1000WHP and do 9's without crushing your sportscar trying to drag-race it. Keep the TT off of the strip and for the maintenance ALONE of dragging your Porsche you can build a 9 second car and have the best of both worlds.

I understand a stock clutch may have problems when stressed on a dragstrip with a high HP car, but then why wouldnt FVD include a better clutch with the Stage 4 package to begin with? Only seems right to put in a clutch that can handle the engine mods. Car only has 26,000 miles.

BlueFVD-575,

We recommend that to all of our customers but in this particular case the original owner opted to keep the stock clutch in until it was ready for a new one. He didn't track the car nor did he drag race it so it please understand that these mods are done on a case by case basis. FVD's philosophy is to find out as much about a particular customer's needs and then recommend items accordingly. No need to sell a $ 1,000.00+ clutch kit if the customer doesn't need or want it. We sold him that kit in January of 2004. So he got 4 year's out of his stock clutch...for him that made alot of sense.

Thanks,
Rhonda

That's information we didn't have...

You spend 35K on upgrades but cant put the power to the wheels!!? Just to save a few bucks? Buyer beware, I guess. My fault for not checking it all thru before buying it.

Whatever. I still wouldve bought it in a heartbeat. Car is unreal. I just still have no idea how to tame it.

Wow...I wouldn't be so down about a simple clutch upgrade. That car is beautiful, the previous owner really took excellent care of that car. Just so you know that kit cost's $ 15,000 and the previous owner only paid $ 12,000 dollars for that kit as he didn't do the plennum. Again that was the previous owner's prerogative. We by no means are in the business of making customer's buy something they don't want to...

What power does the kit make without the plenum?

I found it on the fvd us site

http://shop.fvd.de/us/en/Porsche-0/9...lenum-Kit.html

The plenum adds about 35 hp to cars with modded turbos. So the OP's kit makes more like 540-550 crank hp?... That would better explain the stock clutch lasting 4 years. I burned mine up with a flash and an intake with no tracking!!

Off topic I know, but doesnt 12K for 540 crank seem pretty high??

Rhonda,
By no means was I trying to say FVD didnt do a good job, its just that why upgrade the car by 160hp and not put in an appropriate clutch? Of course the previous owner is writing the check and opting not to, but to utilize all the kit has to offer reliably and without tearing the tranny apart too often only makes sense. You cant cut corners with a car of this caliber, as im finding out. My bad for not checking into the clutch issue first.
The car is a spectacular performer, it kills on the street and track, and it just begs to be driven HARD. Im lucky to have it.
To me drag racing is another way to really enjoy its potential, few street cars even come close. FVD knows what theyre doing, no doubt. Just sore about the clutch is all.
