Ok, so, my rear broke about 2 months ago and I'm waiting for my new MWC fab 9" to come in and I can't wait to get my car back out on the track, but I'm worried I'm going to be disappointed. I keep telling myself 12.2 is all I should expect, but I can't help hoping I'll break into the 11s, so what do you think, here's my setup:

Last dyno tune on 10bolt w/ 4:11s was: 387/385 (w/ cutout after cats)
Previous best on street tires (275/40/17): 12.53 @ 116.12 w/ 1.96 60'

Major power mods:
TR224 on a 114LSA
Pacesetter LTs
LS6 intake
25% UD Pulley
Cutout after highflow cats

Suspension mods:
Koni 4/4s with Strano springs
Stock sway bars
UMI PHB and SFCs

MWC Parts in route (only about a 10lb increase in weight):
Fab 9" w/4:11 gears, Aluminum centersection, w/ yukon posi (I roadrace and autoX too)
Torgue arm, LCAs, Aluminum driveshaft

Tires will be:
fronts: 295/40/17 (Street tires)
rears: 295/50/16s (27.6" Et Streets)

Track I'll be running at is Maryland International Raceway in November air.

Thoughts?

Also, any thoughts on launch technique? I've never launched an M6 car on DRs was planning on 5500-6500 RPM and dump the clutch.

11's are possible but you'll need a good launch. If you can cut a 1.6 or 1.7 you'll be golden. I would start at 3500 slipping the clutch and then work up from there. You'll have to see what the car does and go from there

^^^ I agree your gonna have to get a hell of a launch but i think you can do it.

Damn, now I'm really getting my hopes up. I was thinking on the DRs I'd be able to drop the clutch at like 5500 or even higher, will I just spin the tires like that? I was hoping I wouldn't have to slip too much clutch.

I have a done it with a Hotcam/less mods. I also have a MWC rear and i am a M6 with 4.56 and Hoosier QTP 28 tire, My best 60s was a 1.6 and ran a 11.70 at 115. I think your car can get there. I was launching at 6000 rpm off the 2 step that may help also haha.

Its all going to depend on your 60ft, do you go to the track quite a bit? I think you will be stuck in the low 12's range.

Well it depends what you mean by quite a bit. I'd say I normally would go once a month...but all my previous experience is on street tires having to slip the clutch at like 3200. My best 60' like that was 1.92.

Hmmm...may need a 2 step, admittedly I wasn't feeling so brave to wind it out too 6400 (my current rev limit) for the launch. I'll play with it a while then when I think I found the right RPM, I'll get the two step.

Were you just dumping the clutch or did you slip it from 6000?

I'm impressed with your 116 mph trap speed. I figured you would have been closer to 112-114.

I have my set at 6000 rpm and makes it much easier to launch its one less thing to think about on the line. Myself I side step it which hit the tires to hard but still got me in the 11s, Then I did a quick dump/let it out quickly and this produce the best 60 ft which was a 1.60. really want to get in the 1.5s just didnt happen that day.

Yea, I've heard a little wheel spin with M6 cars is actually better than a dead hook to avoid bogging. 1.5s would be sick. I'll be amazed I I can get 1.6s so we'll see. Hope to have the car at the track on the 13th if all the parts come in and I've got it broken in by then.

That seems about right. It depends on what track you're at and the weather. I ran at the same track as the op if i remember correctly and i regularly trapped 116 with 370hp

z28ss4me

iTrader: (2)

Yea I'm pretty sure we were at the same track. I actually trapped 118 there once and very regularly trapped some 117s but on my 12.53 pass I just managed the 116.

Race weight and D/A matter a great deal. My experience will say a dump at a higher RPM like your thinking will blow the tires off the car, at best expect to Bog. If you get 1.8-1.7 60 foot, consider that a good day and with the cooler air you MAY eek out a 11.998 but you wont know until you get out there.

Ouch, damn I guess I was hoping the tired could hold more than is realistic. I'll have to try the side step method I guess.

BayAreaSS

iTrader: (10)

I agree with him. I don't think dumping it will work. Make sure you post what you run. Good luck

Will do! I just hope I even get to run it this season...I just found out today the soonest I'll get it now is next week. Man, the waiting is killing me. Worst paart is, the track close after Nov and I'm prob gonna deploy in Feb 11, so if I miss this month the earliest I'll get back out to the track is next Aug/Sept.

I'll just cross my fingers it comes in soon and I get good weather this month.

you buy a 2step? Bought mine for speed inc was like $200 and easy install, would be worth it.

z28ss4me

iTrader: (2)

No not yet, I've just dropped $4,000 on the rear and another $400 on tires...just can't bring myself to spend any more just yet. That'll prob wait until next season. Assuming I deploy, the wifey gets a new blower for her pony when I get home too...so I'll add the two step and line locks then.

A couple of things. A 1.6x 60 foot in an M6 is enough to get some air under the front tires. Making that happen isn't gonna go like: bolt in rear, go to track, drop clutch from 6K, run 11s, go home. It can take a lot of work to make an M6 car act right off the line and can and will take a slick. M6s bust DRs a new *******. My 0.02.
