I do have a T5 and a lightweight clutch assembly which might explain some of the differences.

I could guarantee your CG is lower than mine though....

I guess that the carbon deck lid and the tubular IRS control arms took enough weight off the rear to shift our percentage a couple of points.

Sorry, the weight of the car is without anyone in it. The front rear is with my dad in the car.

Do you have a T-5 or a T-45? T-45's came stock in 96- early 01 Cobra's.....

What kind of clutch do you use?

T-5 (not T-45) mounted up to a 2000 R Tremec aluminum bell housing that was customized to fit the T-5 bolt pattern. The clutch is a Quarter Master Extreme-V 8.25" sintered iron fully aluminum assembly. It's light and very grabby.

Don't share info with the enemy Shugg,

Get that car to Mid Ohio in August Thomas!!!!!!!!!!

Any reason you went with a T-5 and not a T-3550?

How long have you had the QM clutch and do you like it? I've been looking at their stuff and am thinking of taking the plunge......

P.S. I agree with John.... bring the car to Mid Ohio in August!!

[svt_coupe]

The T-5 is a little bit lighter and it will live behind the torque monster that is the mod motor. Besides, I could get a T-5 VERY cheaply. Not the case with the Tremec. If the T-5 ever goes, I'll send it off to G-force.

I love the QM clutch. It shifts SOO quickly and the motor spins up so much faster. The clutch has barely worn after nearly 1 year in the car. I installed it before Lowes last year, which was August. The engagement is a bit rough, as expected with a sintered iron clutch, but it grabs so nicely when shifting - there is no slipping. I've done 2 standing starts with it and it was a non-event.

I can't remember the exact figures... but I believe the stock clutch was 40+ lbs. This one is around 20lbs. I highly recommend it.

I know Tilton is coming out with a new clutch assembly that is even lighter than the QM unit, but I think it is a tad expensive. Might want to check into it...

Did you happen to notice a HP increase when you went to the lighter clutch/flywheel as it allows the engine to spin faster which would translate into hp on a dynojet.

Thanks for the reply!

Mark,

I use a triple disk QuarterMaster with a hydraulic TO bearing in my car and LOVE it. Never had an issue with it slipping. The diameter of the clutch is smaller than the one Bryan has and I am still suprised at how fast the car will rev and accelerate. I know some of it has to do with power, but, as you know, the less the motor has to get turning, the quicker you will speed up. My clutch weighs about 15 pounds or so.

As far as a difference in acceleration, Bryan could tell you better since he had a stock clutch before and I have had this one since the first time the car hit the track. Seems like he did say that he could tell a difference in pickup after 'he' put it in.

QM rocks big time. I STRONGLY recommend them. There is a guy there named Jeff Neil that should be able to help you out.

When my greaser mechanic installed the clutch while I sat close by in a rocking chair knitting crochet and sipping on Chateau Petrus Merlot, the car definitely felt better afterward. At the same time, I also installed a Simmons Short Runner intake (oops... sorry, I forgot that the intake installed itself), so it's hard to say that the difference was "all the clutch". I wish I had done a baseline test on the motor before the intake. I got the car tuned on a Dynojet that supposedly shows 10-15HP lower than other Dynojets.

As you know, on the Craftsmen Toolbox dynos we've had at the track, the results have been wide and varied. I still cannot explain these results.

However, on the most recent dyno pull at CMP on a mobile Dynojet, the car made 301HP and I believe 283TQ. Score.

As far as *feel*, it revs smoother, comes off corners harder, and shifts much quicker than I was ever able to before. Pedal throw is very short compared to OEM.

After driving Pearson's 301HP/300TQ car, mine definitely spins better at the upper RPM's. It will pull past 7K (I rarely go there) but some of this is probably the combination of intake and clutch. Though, the engine is butter smooth at that speed where before it would protest much earlier in the R's.

Thomas,

I'm sorry to drag this tread up again but I was re-reading it and something isn't clear. Is the 2875 lb weight with you in the driver seat or not? You answered that the 59.2/40.8 weights were with driver but you didn't specifically state that the total weight was with driver.

Do you have the stock front and rear glass in the car with that weight?

When are we going to see you at the track?

[spittincobra01]

Mwilson,

according to SVT all 01 cobra's came with the 3650. The changeover came mid 99. I had inquired when I was shifter shopping.

Thomas,
those are some really impressive numbers for weight! Especailly considering how pig heavy these cars are out of the box.
