M6 car with MS3 cam...lacking power?
#81
I took it to the local track today and I wasn't very impressed. First of all, this track was prepped terribly. I actually get traction on the street if I launch the car...not so much at this track. But we don't really care about ETs for this discussion...check out the trap speeds...
60': 2.469
1/8: 9.164
MPH: 83.80
60': 2.504
1/8: 9.248
MPH: 84.27
60': 2.476
1/8: 9.188
MPH: 84.75
My last Camaro was an '02 SS auto and it ran an 8.7 @ 83MPH stock! 8.4 @ 86MPH with LT headers and a tune! Something isn't right here...

So the car is underperforming, how much of the history of the car do you actually know. Did you visually confirm that it has an MS3 or is that just what the previous owner told you?
#83
I only know what he told me but even if it isn't an MS3 it should be trapping higher than that. It clearly has a healthy cam in it so it should be doing a better job than the stocker. The clutch felt kinda mushy after each run but it didn't feel like it was slipping...no noticeable RPM climbing without going anywhere or anything like that (other than the spinning of course).
I guess it really is valve float? I'm going to replace the clutch for good measure too but I don't think that is the culprit...just a precautionary measure.
Here is an idle video...not a good way to identify a cam but at least you can hear that it's at least pretty healthy if not the MS3. The previous owner did give me a cam card though...not sure if you can print those off anywhere or not so I'm not sure how much that helps the case.

Yea...not really sure what I can do about that. I could try a different track I guess. I tried everything...first go around I launched it at 2000, second at 1500, and then finally I just revved it and let it fall down to around 1500-2000 and half rode the clutch for a second before I went. Nothing worked. I don't have any suspension work though so I'm not really complaining but I still can't believe how bad the track prep was.

This thread is moronic! You start talking about being down on power cause you can't spin the tires, then you post track times with 60ft's in the 2.5's? Its no wonder you ran shitty times. Then to top it all off you say, "we don't care about E.T.'s just look at trap speed". An MS3 and stock gearing is about as far from a good 1/8 mile set up as you can get! I can easily imagine how a stock A4 Z28 could run better times in the 8th then this car. My advice to you is go trade this car off on a civic, and buy a stereo. You'll be much better off...

What tires are you on? Regardless of tires, you shouldn't just drop the clutch (on the stock rear), it will just shock the tires and do what your doing... your gonna have to slip the clutch out to get a decent 60'. Even on street tires you should be able to manage a 2.0 60' slipping the clutch, just takes a little practice.

*Car does not spin on the street. The track prep was terrible.
*I don't care about ETs for the sake of the power argument. I only went with the intent of seeing what the car would trap so that I could see what kind of power it has.
*So you're trying to tell me that the stock 3.42 gearing is costing me oh let's say 5MPH trap speed? I have personally trapped 93.95MPH in an f-body that put down 413/414 so I would think that 90MPH isn't out of the question for a cam only f-body.

I've read this whole thread (several times actually) over the last month. The only thing we've really learned here is that your an idiot that shouldn't be allowed to run a leaf blower, much less a motor vehicle...
#92
people like this is what pisses me off about internet forums. If you think the op is an idiot why are you reading his thread and why are you commenting. So op hope you get your car fixed and dont let forum cowboys or trolls get you down.

You really need to get your 60ft down. You shouldn't be dropping the clutch on these cars to begin with, Even with bad prep and street tires you should cut low 2's, maybe 2.1-2.2 60fts is normal. Slip the clutch out around 2500 3k. The fact that you trapped 83 84 with a 2.5 60ft is actually pretty good but it's all little things that add up in the end.
