Has anyone ever had a SPEC III slip? I was out messin' around last night with the 75 shot, and I had it slip one time REALLY BAD!!!! on me.

It was 31-32 degress (I was thinkin' that may have something to do with it), and I was cruisin' down the road. I let the bottle heater warm the bottle up to about 950psi, and I let it rip a couple times. I guess cause the road was cold and all it just spun the tires horribly when i hit it in 2nd at about 40mph. So , I slowed down, and when I got back to about 4000rpm's in 2nd I hit it again. This time I let it spin for a couple seconds, and proceeded to hit third. When I hit third it grab for a brief second, and then went bangin' off the rev limiter, and not because the tires were spinning either!(not good with the nitrous ). That was the first time in the 6 months I have had the clutch with the nitrous that it has slipped on me...especially that bad!

I was rather upset with it at this point so i did a couple more times to see if it would slip again ,and it did not.

Does anyone think it was a "freezing clutch" that did this? Cause like i said it has not done it before...and when i took it to the track last friday, and tortured it for 4 runs with the 35 shot and 4 runs with the 75 shot it didn't slip...NOT ONCE!

Maybe a mixture of 19" wheels and a freezing cold clutch gave it no choice but to slip

are the spec 3's kevlar? I do believe the 2's are. I wounder if the cold kevlar is more prone to slipping.

Nope just the 3's are kevlar.

no...stage 2 is kevlar, stage 3 are ceramic pucks iirc...or some organic stuff, but pucks nonetheless.

you know I was just out in my room thinkin' about what I posted in response to that...and I was like..."did I say MY clutch IS kevlar?"

I don't know what the hell I was thinkin'!!!

I meant to say nope just the 2's are kevlar! lol

must mean its time to go to bed!

Never had it slip unless I was riding my foot close to the pedal. Even a very little pressure on the pedal between shifts is enough to cause it to lift off some pressure and then it might slip.
My wife did that just last night and because she was being lazy she didn't lift off fully before she nailed the pedal in second gear. Funny, it was because this guy in a Dodge RT 5.9L (I think that was the size.) took off. She just stayed with him up to the speed limit.
Actually she did everything wrong, I was pissed.
She takes off tires spinning out then its just bouncing off the rev limiter like four times before she shifts. I was just starting to say something. Then she nails it in second and I can hear it start to slip and then she lets out all the way and it takes off.
LoL! I was too busy laughing at the dude in that truck to pay attention to all that she was doing wrong.

Afterwards I explained that same fact to here that I explained to you.

Anyway, the pucks are sintered bronze apparently. There may not be anything wrong with it but I'm not sure what it will do when it is getting close to its limit.
Mine have always worn similar to a stock clutch.

Still, with those temps and a hot bottle, you were probably pushing 400 ft-lbs. Hell, I push close probably 350 ft-lbs at the flywheel. You're running a serious shot on an engine that is really efficient with nitrous. You just might have been getting close to exceeding the limits of grip.
Still, I'd check to see if you just weren't letting off on the clutch pedal all the way first.

400ft-lbs...with a 75 shot on a 2.5... . Maybe not that much there Tom lol

I actually thought about that earlier today also...about not letting off of the clutch all the way. This darn Spec thing is weird sometimes after you drive something else that engages in a different spot. I mean...the clutch literally has one inch of "engagment area", and it is ALL at the top of the pedal!

Actually, don't be too sure about that 75 shot.
Every 75 shot dyno on our cars has been like 100 hp to the wheels! Plus the torque loads go really high when the nitrous is first injected, probably approaching that 400 ft-lbs at the flywheel.
I know my own car on just a 75 wet shot out of my 2.5L was easily as good as running my 3L turbo on 8 pounds of boost! I mean it felt comparable in every way except that the torque was monstrous all the way.
I'd have a hard time believing that anyone with a decently dialed in 75shot on a 2.5L isn't pushing more torque in the lower rpms than the 400 HP turbo guys.

Ok well when yout think about it in those terms it could be. I LOVE the feeling of the nitrous ripping the tires loose ...but i hate the bottle running out! lol
