OK guys.....on my quest to have a 10 second street car....the biggest hurdle seems to be traction. The best I can get out of the car with Mich PS2 345/30's is 12.00et's.....spinning half the way. After Lingenfelter built the car it has a stout 500hp at the wheels. The car is a 6 speed manual, with stock gears. No I did not expect to get into the 10's with the current street tires.....but what about drag radials??? Is it possible, with the right track, right conditions and a good set of drag radials, to break into the 10's? My favor I ask of my fellow FI guys......list 3 things that will help me get into the 10's in the drivetrain department. No NITROUS either!

1.?
2.?
3.?

The guys at Lingenfelter say the power to get there is under the hood.....it is all about hooking the car up at this point. I look forward to everyones top 3 choices. Thanks a bunch guys!!!

 

LPE is absolutely right. The power:weight is THERE!

1. Good tires
2. A good driver
3. Nothing else!

M&H makes a nice 18" 345 Drag Radial that will give you the 60's you need to run that oh so elusive 10.90.

 

Awesome.....glad to hear my goal is within reach!!!

 

What MPH are you traping now with your current setup?

 

my .02 would be tires and learning how to modulate the power. I can tell you if you are spinning that much you hitting the car to hard out of the hole.

if you are runing 12's with 500rwhp it is all chassis at this point. considering that cars 50-60 less rwhp than you have run consistant 11's with no problems.

I mean you don't need 500rwhp to run a 10sec pass. I have heard rumors of stock z06's on the right rubber running real close if not high 10sec passes. I have not had this car to the drag strip yet but I can tell it takes some getting used to launching and I have 50hp less.

look at trap speed and your 60'. I would be you have horrible 60' and a tremedous trap speed.

you may have a classic case of a bit too much power ha ha. everybody always seems to want 500 and 600 rwhp but getting that down to the ground takes good driving and good tires. I have never looked up the numbers but I would bet a bone stock C6 with gears and slicks would run times that make peoples heads spin. I know my 08 ls3 felt strong but the gearing and traction was not optimum for optimal quarter mile runs. I mean 4th gear went to 150mph usually you want to close to redline in 1:1 if you were building a car for optimum quarter mile passes.

 

just a good tire prob the M&H's the best one out there. if that dont do it just add more power

 

just a good tire prob the M&H's the best one out there. if that dont do it just up the boost

 

1. Seat time
2. More seat time
3. Yup.. a little more seat time.

If your still running 12's, then nothing in the drivetrain department is going to help you. It's hard to compensate for lack of skill in just 1/4 mile, you just need to work on your launch and reducing wheel spin. Keep workin' at it, man! You'll get in the low 11's at least, just takes some honest practice.

 

you need to get the wheelspin situation under control and your ETs will fall dramatically. What are your current MPH and 60' times?

 

I was just was looking over some old time slips.....I hate to say HORRIBLE 60' times.....the one I am looking at now shows 2.313 but as you can tell the car comes on strong once it does bite by the 122 mph trap speed! The car is a complete handful on the track with the street tires.....I tried launching at all different RPMs.....if I bog it a bit off the line and short shift into second....once the car comes under full boost in 2nd the tires melt at 50mph...and that is where it gets a bit scary.

So does anyone think I need a gear....or just TIRES and more practice???? Thanks for all the responses!

 

I had 520 RWHP and ran 11.40's with 2.1 60's and STOCK 2.7 gears in the rear. I added a stall and a set of 3.42's in the back and got into the 10's before I sent it away to get into the 9's. I am hoping when I get my car back next week that there will be a nice night for test and tune down here. I ran a 10.40 with 2.0 60's and spinning thru 1st and 2nd gear before I sent it away with 690 RWHP. Back to you....

You can FOR SURE run a 10.90 with more seat time.
So I would say....

1) TIRES!!!
2) SEAT TIME!!!
3) YUP!!! SEAT TIME!!!

 

I don't thing a new rear end is going to help you... Not sure how much lower you can really go without killing the fun factor, and obviously if you go any higher the problem will just get worse.

Tires will definitely help some with the 50mph thing... and some petal control will help a lot.

Try not to get too aggressive too fast... It's easier to start more conservative and work your way up than to start aggressive and try to work it back down. Work to get the wheelspin under control, THEN start trying to improve on that 60'. Same with the 2nd gear issue... Work on control, then once you can consistently run a clean lap you can start working on the ET.

I don't think there are many on the forums getting great times with the maggies, mainly because it's a lot more difficult to control with all that low end torque. But if you put in some good honest work behind the wheel, you can certainly get there... especially with good rubber.

 

Something is BAD wrong with your 500 RWHP C6Z if you are consistently only trapping 122 MPH. You should be trapping 126-128 MPH at the very least! Are you sure LPE did the work to your car? Also, the more I think about it, I don't know of any packages from LPE that only offer 500 RWHP...? That's literally only headers and a tune on a C6Z.

Stock C6Z's on stock tires are trapping 122-124 all day every day.

 

Something fishy here. LPE does a blower kit and gains
maybe 65 rwhp over stock? A blown Z with 500 rwhp? Then it traps 122? When alot of stock Z's trap fasterI trapped 120 with 420 rwhp. My blown ls-3 better be trapping much faster than
122!

 

It's not a Z... It's an 07 C6 with an MP122. LPE doesn't even make a supercharged C6Z. If you read his mods, it states he has the "Z06 rear fender package." It's definitely a legitimate LPE package.

 

Thanks for clearing that up.....it is NOT a Z06...just a standard C6.

 

You will need either drag radials or a CCW drag pack.... AND a lot of practice launching the car. I don't know how you took it to the track on street tires....I can't hook under 55 mph. The problem with the M6 is the rear end once you get some traction.... I saw an LS3 and Z06 both go down at the track in December.

One of my friends had a C5 coupe with a Maggie 112 and just revved up to 5k rpm and dropped the clutch.... that was his launch technique. Ran 1.6 60' times with his M6.

My best time so far has been 11.07 at 127 mph with a 1.7 60' time and I have similar mods (A6, maggie 112). The track was not hooking when I was there and I should be in the 10's next time out. I was blowing the tires off leaving from idle.

 

Even being a non Z06 C6 with 500 RWHP should trap higher than 122. It might be time for you to stop by a dyno and get a second opinion on your tune (just so you aremn't chasing your tail).

 

He just needs some sticky tires and some practice and he'll be in the 11's easy.... Deep 11's and 10's with some luck.

I know you have a lot of experience with high power cars, but the maggie makes huge power down low...and falls off up top. If he has stock tires, he is wasting all the low end torque. I blew the tires off leaving at idle on ET streets, so I know that he had NO traction.

 

In my opinion.....I think the guys at LPE have the tuning down to a science......it certainly has the power http://www.youtube.com/watch?v=E6X99PWtWMM

I am convinced at this point.....TIRES TIRES TIRES......practice practice practice....and hopefully nothing breaks! Tim at LPE tells me the stock clutch will most likely slip before anything flies apart....of course that all depends on launching the car correctly. Well as soon as spring gets here....back to the track for more practice. WINTER SUCKS....9 degrees outside right now and 2" of snow....hate this crap!
