Launch
 

Curious to see what everybody who has an M6 car launches at. I have my LNC-2000 I use to pull timing for my nitrous. But have not wired it in to do the 2 step. It’s a 2015 1LE Cam, Bolt ons, Runs on Ethanol/Ignite, motor mounts, 6 puck clutch and nitrous. 650+ when turned up, head work (stock port) 17x10.5 rear on the new set up I’m getting with 17x7 fronts.

3500-5000 depending on how the tires stick. It all depends on the tires.

On the stock clutch with some 305/45/18 i was doing 1800-2k launch and worked really well. Now I have a spec stage 3 clutch with a billet steel flywheel, and the new wheel and tire set up coming as well as us turning the car up since it has a clutch and now an AUX fuel system I made. Should make 650-700 when it’s turned up. All the way turned down it makes 530. Lil small shot of nitrous. Had stock 20s up front as well previously. Now I’ll have the drag pack all around.

305/45/17 ET STREET R
215/65/17 Fronts

That is the combo I’m going to run. Mainly we do street stuff, but I have been getting into events and what not as well.

I ran my car at the track for the first time yesterday. I'm running a n2mb WOT box with 275/40/17 M/T ET Street R tires and the mods in my signature. I was launching at 4K rpms, and I think that might have been too much because I spun both times I launched. Only got 2 passes because of a high car count, so I didn't really get to practice much. I probably wasn't slipping the clutch enough on the launch. Hard to tell, but if I can't get it to hook up with the clutch I'll likely lower the 2 step down to 3.5K rpms and see if that is better.

Unfortunately, it's completely dependent on the track and the tires. I've been on street tires that needed to leave at 2400 to work right, and I've been on drag radials that wanted to leave at 5000+. Usually, I try to pick a starting point I'm pretty confident will be lower than what the track will take, make a hit, see how it responds, and then dial in some more for the second whack, rinse and repeat till I step over what it wants and then I've got it about dialed. I also always preload the drive line, try to get out any slop so it doesn't get shock-loaded as hard, and then I use a (relatively) slow clutch release.

You explain this stuff so well Andrew. Too bad I forgot everything you taught me when I got to the starting line! :rolleyes:

Thank you for the info. I def know it depends on surface and tires of course. Just wanted to kinda see what other people were doing to get an idea. Cars been 11.1 at 121 MPH in the 1/4 on Motor. So let’s see what she’s gonna do on bottle. Got about 250 more miles to break in the new clutch, installing AUX fuel set up this week as well and then off to dyno to turn it up and then we go from there.

Lol - I was pretty confused on how you got got DR2's to spin so bad when you messaged me, but once I saw the video it made a lot of sense. I bet replacing a brand new ring gear will etch deeply into your mind the need to be easy with that left foot. Live and learn.

Wait, where have I been? Z, you ran? What was your time, you got a video?

There is a video on the 5th gen Camaro drag race FB page. My GF posted it and I don't have the raw video. https://www.facebook.com/carol.vasel...5752741223972/ If you can't see the video, It was posted again in the comments and should work.

I suck and I need more practice. Only got 2 passes at the first test and tune. My best was 12.73 @ 115mph w/ 1.98 60'.

I'm going to test & tune again tomorrow. I hope to show some improvement in both the 60' and the ET.

Having a very hard time getting any good times with mine as well. Just can't seem to get it off the line and rolling without blowing the tires off. Even lowering the tire pressure to 25psi, it still does it.

What kind of setup do you have, LSLuvr? Have you thought about bumping down the tire pressure a bit more? When I ran 18" wheels on NTO5Rs, I did 19psi with an 8 second burnout. Now I have a 17" wheel with MTs and run 22 psi with like a 2-3 second burnout and I can hook well on a decently prepped track.



It wouldn't let me watch it, but thats cool that you got out to the track. The weather being warmer and all makes it harder to get those good times you're looking for, for sure. 115 seems a good trap speed for a 12.7 at least so it sounds like you could have way better results next time:headbang:

Sorry about the video. Anyway, i'm going back to test & tune tomorrow, so hopefully I have better numbers to report afterward. Wish me luck!!

Give it hell, have fun
