Haha, I don't know about that, but thank you. I'm still learning each time I go out to the strip.

Just when I was getting the hang of the full throttle "accelerate into the clutch drop" method, my clutch let go.

Man! I'll be glad when you guys sort this out so I can get some good cam specs also...........

JUIC3D

There's not much to sort out.

Spin's cam makes great power with minimal overlap which equates to nearly unmatched driveability. It's a relatively mild cam that makes great power and is proven over and over.

Pat G specs a cam for you and your specific goals, mods, motor, tranny style.

You don't need a "big nasty" cam to make power in the LS3 motor as has been demonstrated over and over.

You can go big and have a rowdy lope at idle and obnoxious street manners on light throttle, but it isn't necessary if your main goal is the most power out of the car.

What you Guys think about TSP 231/236 cam its very popular within 5th camaros...

CDaniel525

Sounds like what I want

Pat G said hed hope to have my specs done by tonight... Ill post them up as soon as I get them!

JUIC3D

Sounds good. I look forward to it.

JUIC3D

TSP knows their stuff. I'd trust them if you just want an off-the-shelf grind.

CDaniel525

Ya, just hope im not going overboard... thats all, lol
Id be perfectly happy just being able to break into 10s with the skinnies, DRs and a cam that sounds bad ****

JUIC3D

You auto or 6 speed? It's fairly easy with bolt-ons and cam and somewhat decent air to go 10.99. Every .1 after that though. . .that's a little more difficult.

dennis50nj

that's exactly what i said, with just bolt/ons,went 10.92 and it wasnt good enoughso 10.8s should be easy with a cam

JUIC3D

For me, it was much more about trap speed than ET. I wanted a 130mph car and so far, my current best is 128.7. That was with +850 DA so I think with a little luck and better air, I'd be there for sure.

CDaniel525

I have a 6 speed manual...

Wow Dennis! how did you run 10s with just bolt on? I consider myself an OK driver, beats were 12.24@117 bone stock run flats and 11.8@121, still run flats with headers, offroad xpipe, z06 mufflers, vararam, 160tstat and Eva tune... But 10s is impressive!

CDaniel525

Since you guys are excellent drivers, how r u launching at the strip? Justin, what do u mean by the above, accelerate into clutch?

dennis50nj

i have an automatic and the right combo and tune dragpack 373 gears 3800 converter ewp headers pulley ported fast and tb vararam lightweight battery low fuel good track prep good da, went 10.62 put a cam in only went 10.59 but at 130 mph with no traction spinning very bad at part throttle, made some changes but still spinning, i will get it worked out one day. i live right of 70 near redlion circle if you ever get up this way let me know

CDaniel525

ya, definitely would love to check out the car... I actually live right off rt 70 as well... right as you get out of Manchester. Sending you a PM in a min.
I think you mentioned having a cartek cam, do you know the specs?

JUIC3D

I'm not proficient in full throttle launches just yet, but looked at a couple of my logs, I'm getting there slowly but surely.

Previously, I would bring the rpms up to 6000-6500 and let the clutch out, slip it until I felt the tires grab, then let the clutch all the way out.

This technique would get me solid 1.6-1.56 60fts but I think there's a better way.

Joe_G and I are buddies and I try to mirror his style, as he's the one who essentially taunt me how to launch these cars, and what particular aspects of the log to review for areas of improvement.

Instead of holding the rpms steady on the launch, I'm starting to accelerate into the launch while letting the clutch out quickly. I try not to go slow enough to have a bad 60ft, but not too fast where it sends the tires up in smoke.

If you do it right, you'll be at 100% throttle before the car ever moves, the nose of the car won't dip on the launch, and you'll see low 1.5 60fts on the timeslip.

Go back to the video I posted in post #33 of this thread. Here, I didn't have the rpms high enough and as such the nose of the car dipped down at the launch, which cost me a little ET and MPH on the run.

CDaniel525

OK, guys... Pat got back to me with some specs, here whats he suggested. Let me know what you guys think!? Hows it gonna run, idle, driveability, HP predictions!?

JUIC3D

That cam is a very similar cam to what I have in my car so I'd expect the performance to be close. The intake lobes are different, but the exhaust lobes are the same.

Essentially it's the same cam I have but you have LSL lobes compared to my EPS lobes.

You've seen my dyno and videos so assuming you do all the supporting bolt-ons, I'd expect in the neighborhood of 480-495whp

CDaniel525

That's pretty much what I was thinking Justin. Wonder what the difference in the lobes will do?
Only thing I think I'm not doing as far as supporting bolt ons is the underdrive pulley, other than that I think everything's else is close.

JUIC3D

Why not an UDP? It's free power.

I'm curious to see what your torque will look like as the EPS lobes are supposed to carry it out a bit further. The biggest point Pat mentioned about them is that they close the intake valve just a hair softer to reduce the 'sewing machine' noise.
