If a pure stock C6 (it would obviously only be a manual, a stock auto could never do it) could see the 11s at all it would likely only be a very, very high 11 (11.99999 LOL) IMO but I would also like to see Ranger or someone of similar abilities try it as well.

 

Thanks for the generous words.

Well, gents, I do have a record to maintain, three C5s/C6 drag raced with no breakage. So I doubt anyone but I, will be making passes in my current car.

But I'd love to make some passes in any stock C6 w/manual tranny. Probably take three passes to get some idea of the rhythm of the LS2 and the shifter. I'd hazzard the guess of a best pass within two tenths of whatever I'd do if I owned the car and made 30-50 passes.

I plan to be at Atco, October 23 and Nov 17 for track rentals. And I'll be a Cecil on October 13 for another rental. If anyone is interested in such a test of their car, please let me know by PM.

I'd prefer a bone-stock, stock tire car, or best offer.

Ranger

 

I do believe that if a 1.82 launch could be achieved that would put my car at around a 12.15 at 115.85.

If someone could beat my 1-2 and 2-3 shifts by 0.05 each, there would be another 0.1 and knock my times down to a 12.05.

Make this at ATCO which is about 0.1 and 1 mph faster than E-town and you could possibly see a 11.95 at 116.85-117.85.

But, I don't see it happening.

Wow, Ranger holeshot me in this thread, maybe he can do it

 

I'll be there (spectating/crewing for some friends) on the 23rd (and maybe on the 17th as well) so I'll see ya there.

 

In current trim or once the long tubes/tune go in?
I don't think your car will see almost 118mph as it sits unless the DA is like -3000 ...with the addition of headers and tune though I'm almost positive that it will.

 

I might suggest that owners trying to shed time look for wastage that others overlook. A good place to start is (1) coolant temps, (2) shift points, and (3) heating the tires. Those elements ripple causative consequences through the splits and incrementals.

Ranger -

I have my coolant temps in check, and my shift points are pretty well in check also, but the heating of the tires with a manual tranny is where I catch a snag.

I am afraid to do a second gear burnout, I just can see that glazing my clutch.

I am also not able to dump the clutch in 1st and jump back on the brakes to keep it still.
So all I get is a couple second of spin to clean the tires.

With my automatic a lengthy burnout had my runflats sticking very well.

I did get to compare my stock runflats to the Z51 runflats.
The Z51 runflats are stickier for sure and maybe at my next tire change will be an option.

Howard

 

That's true, 220 treadwear rating versus 300 for the non Z51 runflats...I dead hooked to that 1.88 and 1.90 sixty foots after a good burnout on my non Z51s but the auto also doesn't hit as hard as the manual. Of course TM (on an untuned car) becomes a factor in trying to dead hook either tire with a manual as well, a little spin on launch might actually be a good thing in that case.

 

Exactly what I found in my runs (although I didn't try shifting myself since it was during bracket competition).

 

LS1LT1 -

I might try the 220 runflats next time.

They definitely have to be stickier.

Howard

 

Dennis50nj has had great luck (1.7s) with the Supercar runflats as well.

 

Yes the vortec ram air system.seems to work well with my car

 

Had the very first pass made in my 05 C6, Z51, MN6 with the following mods:

Procharger D1SC Supercharger
AFR 225 Heads
224 230 581/592 114 LSA Cam
160 Degree Thermostat
Corsa Sports
DynaTech SuperMAXX Headers

The car makes 586wrhp and 506rwtq. The wheels spun in 1st, 2nd and 3rd.

12.27@121.60

This was done with a stock clutch and DRs. I will be adding the RPS clutch and flywheel so the car will be able to hook up. Not happy with the ET, but really pleased with the MPH.

 

Please move me up just a little bit.

I believe there might have been a 12.80 in there, but I can't locate the slip. I'll let you know when the video tape has been reviewed! For now, however, my best slip now shows 12.883 at 108.38. This is still with Borla catback and DRs, and a bunch of practice. Temp was approx 89, I believe. Typical South Florida fall day.

 

I'm no expert on the subject, but I've been getting a little better at the burnouts. I've been placing my heal on the brake, while I apply the throttle in first and let out the clutch. I try to keep the rpms at around 5k, and after the tires have spun enough, I ease off the brake and roll forward a little as I let off the gas.

Ranger has more detailed instructions somewhere. Ah, here it is! Search is a good thing! As a matter off fact, I just reread it and now wished I had done so yesterday, before I went back to the track. Oh well, I'll keep working on it!

 

cmb13 -

Thanks.

You know me by now, I've searched before and read that before also

I still think doing a burnout in 2nd gear could have negative consequences.

So, unfortunately without a large burnout I am probably giving up at least 0.1-0.2 on my 60' and 0.2-0.4 in my 1/4 mile times, but at least I KNOW my car will not break.

Like Ranger, I have NEVER had a car BREAK at the track while I was driving it.

I have never had a car that needed to be towed home.

I might actually have to try your heel on the brake method in 1st, I just don't know if my bones will allow me to turn my foot in that position

I wish I had a place around here where I could practice that before my next trip to the track.

I do believe mid to high 1.8 60's are possible with the Manual C6 with a good burnout, without one I am VERY happy with low 2.0s.
When I see a 2.1 or worse I know it was not a good run.

Thanks again,

Howard

 

When I owned manual cars that I drag raced, I found the better burnout method was not to use the heel on the brake, but to use the left foot instead. I would rev it up with the clutch depressed, then as soon as I let off the clutch I'd move the left foot over to the brake immediately. When I watched videos of my cars, you couldn't even tell I was doing it this way since the car would not move forward. Ya gotta be quick, but this method works much better, it gives you way more control over the throttle and you can hold the brake much better.

As far as the 1 vs 2 burnout, it all depends on your gear ratio. I found with my 3.42 M6 98 Formula, it was best to do the burnout in first. But once I swapped in some 4.10s, it was better to do the burnout in second gear. Because of the 4.10 ratio, first gear finished up much sooner, so a first gear burnout with that ratio resulted in the tires not spinning as fast. Second worked out much better. Just be sure you don't do a second gear burnout in a completely dry burnout box or you'll put too much stress on the clutch.

Part of me misses the days of racing manual transmission cars, until I remember all the missed shifts! Even with well over 1000 quarter mile runs in manual cars, I would still miss a shift from time to time, always on the runs where it most likely would've run a new best too.

 

Patman -

I am afraid I won't get on the brake fast enough or I'll get on it too hard and stall.

 

You're going to have to do a decent burnout at Atco, those tires will just be too wet (going through the water box is unavoidable there for those that don't know) to launch well on otherwise.
