New track times after cam and Intake

93CobraR · 06-08-2001, 10:59 PM

Well, put it this way, I'm not to happy with the car. Heres my best ticket of the night
.924
1.741
5.208
8.129
84.29
10.638
12.759
106.79
I just ran a 12.9 not to long ago, and I added the Edelbrock intake and Crane Cam, and picked up 2 tenths or so but almost 4 mph?? What gives on that? One thing is my 60' times weren't as good as before, I'm almost possitive that my 130k traction lock has had it, I was noticeing that the drivers side tire wasn't spinning as much if any at all as the passenger side. So what do you guys think? 130k on the stock motor, $300 heads, $150 cam, $350 intake and I'm on my way to the mid to low 12's with some tuning.

What the hell are you disappointed with boy. Your motor is blessed. 106+ mph is awesome.

It's just that I picked up all that MPH and not very much ET. I'm going to rebuild this traction lock and go back next week. I really need to tune it. Like I said, I have no idea what my fuel pressure is at. Still stock injectors,pump,ect... I wonder if thats holding me back any?

302man · 06-09-2001, 07:56 AM

I would do 2 things, both you already touched on. Get traction. Either rebuild /buy new differential or try changeing the fluid to standard gear lube with NO fiction modifier. Secondly, add an adjustable fuel regulator. Raise the fuel pressure until it slows down. Keep a good log book to reflect on, it helps. Also, your 60ft could be down just because now you are making more power down low. Your engine is up to par, now get the rest of the car to match.

Thanks, I do have a adj. Fuel reg. but no fuel pressure gauge yet.

Also my traction is really good, it doesn't spin at all, my best 60' as you can see in the sig is a 1.695 which from what I have seen is what most 11 sec cars pull. The reason I think that they were at 1.7 last night is because either the traction lock or the new cam doesn't pull as good down low?? As for the differentail I'm just going to put a spool in it or weld up the spyder gears. I had that done on my other diff. but when I put the gears in I switched it out for another one.

red82gt · 06-09-2001, 06:37 PM

You did try upping the launch RPM's to match the shift in powerband of the cam, right? How did it behave off the line? Spin, or bog?

I was launching at 5500 on my auto meter, so right off the shift light. It didn't jump like it usually does. It surley didn't bog, or spin.

red82gt · 06-09-2001, 10:54 PM

If it didn't spin, go higher!

93CobraR · 06-10-2001, 09:19 AM

Yeah, I thought about that but then I thought about what would happen to my stock axles and 160k mile tranny?? lol

Rick 91GT · 06-10-2001, 10:33 AM

Hey, those results look good the 106 mph is great. I like you also need to do the rear I don't think my 180K mile axles and carrier are going to take the 5500rpm launches for long either. With some tuning you'll ge that combo down, don't worry.
