RWYB C6 time estimates?
Discussion
Myself and a few blokes from work are likely to find ourselves at Santa Pod sometime in the not too distant future for a few runs up the strip on a RWYB day. I've been up there before when I had my C5. That car was an auto with intake, Borla exhaust and a tune and the best time I got was a 13.78. Not great, but the track prep was poor (sand all over the staging area) and I made the beginner's mistake of letting the car idle and heat-soak in the queue (it was in the Summer, too).
Anyway, so fast forward to the present with my C6 stick-shift, BPP Vortex Rammer intake, Borla exhaust, Diablo Predator tune and Michelin PS2s all-round. I know I could get times from the likes of corvetteforum (where I'm a long-standing member), but has anyone here run stock/near-stock C6 in the UK for time comparison purposes? I'd hope for a time in the high-12s, with a decent 60' time.
One of my work mates has a Mk.1 Tuscan S, which I only found-out today has a factory 0-100mph time of 8 seconds on the nose. Very impressive, considering my C6 takes a factory-quoted 9.9 to do the same task. But, in the real world, on a real drag strip, what do you reckon?
When I've got the Cobra (Dax Tojeiro) fixed again, I'll take that up to the Pod... that'll be a hoot!
Just looking for some light-hearted debate!
Cheers,
Ian.

I'm guessing it's not stock then? That or an ex-press car, they were always a little bit 'too' quick. I drove a Tuscan S again in October for somebody and was amazed that I ever thought they were fun. The floor mounted pedals meant that to get to WOT I had to dislocate my ankle, nor could I find any remnants of steering feel.Ian.
On your drag query I'm willing to bet that a good launch could see you in low-12s possibly high 11's. Alot of the drag boys on the corvette forum are in states which are inherently warmer than our country so you get a significant cold air induction benefit. You've just got to make sure you find some appropriate tyre heat or it won't be going anywhere! Best of luck

My mate's Tuscan S didn't feel as fast as the on-paper figures suggest (even though it's just had a top-end rebuild and is known to be healthy). I don't really know why people rave about the sound they make, either. The only TVRs that sounded good were the Rover-engined ones (ie. the old wedges, Griff and Chimaera). The AJP V8 is flat-plane crank, so sounds like a pair of 4-cyl engines operating in unison (unlike Ferrari V8s which use the same flat-plane design, but sound incredible). He already commented that he doesn't get that wall of torque feeling that the Vette and Cob have :-)
Loud and clear on the pressure side of launching at a drag strip, but as with racing a deep breathe will go a long way. I know Ranger managed a 10 in stock Z06 so I don't see why you should be so far off that. A bit of practice.
Rover engined TVR's were the best, particularly Chimaera 450s and Griffith 500s. The flat plane crank in the straight six sounds like a bag of nails to me and the distant memory of feeling like you were driving a grenade wasn't and isn't my cup of tea. Bring back the Griff is my vote!

I think Mitch is being way optimistic. Yes Ranger got a 10 in his Z06 but he (and maybe his car?) is very much an exception and has done thousands of passes.
Mid-12s should be attainable, but don't forget to drop your rear pressures to the low 20s (ignoring your TPMS's protests) and do a decent burnout. You should still be able to switch TC but leave AH on.
Optimum launch revs are probably much lower than you would guess too. I would start at 2k with a quick (but not sidestepped clutch release).
Do a search on Corvette Forum for Ranger's techniques. Some excellent stuff there, particularly about shifting the Tremec at speed (basically let the spring push it into the 3-4 plane for the tricky 2nd to 3rd shift).

Regarding the 2-3 shift, I've had zero problems since installing the B&M sport shifter. With the factory set-up, I found myself in 'no man's land' several times when shifting hard from 2nd to 3rd... a weird zone where the shifter feels like it's in gear, but isn't.
I'd be very happy with mid-12s. I'll definitely drop the rear pressures. I need to work on my burn-out technique though... the first (and last) time I tried it on the worn-out runflats, the rear of the car swung out and I had visions of launching into the curb! Need to find a nice big, deserted car park somewhere and practice.
Cheers,
Ian.

Well you're never going to manage if you start off with that kind of attitude David. Remember PMA! 
What does that stand for? Pre Menstrual Attitude? 
A quick search on Google shows that NOBODY has got a standard C6 on stock tyres into the 11s. It simply can't do it.
In fact 12.5 is very, very good going, so just getting into the 12s on a cold Pod surface will be excellent.

Jenkinscomp regurly runs a Z06 at the pod and from memory runs 11.7's @ 120mph. But I'm sure he'll look in and advise..
I've not seen any stock C6's run this season, but stock C5's normally run between low 14's and mid 13's depending on the track experience of the driver.
The biggest struggle & killer of time is getting a good launch with minimum tyre spin on the stock tyres.
If you get the '1/4 bug' then the first purchase needs to be a pair of Mickey Thompson drag radials the difference they make to launching is awesome.
My PB to date is a 12.3 in my 'stockish' '94 C4, but that's with a shot of gas..

Must be one of the quickest out there.

Totally agree. I'll be happy with sub-13.As Jakester mentioned, I ran my Z06 to a best of 11.7 @ 123mph, matching the factory times.
I used Rangers advice from his excellent website and thoroughly recommend that you do too.
Briefly, that is to ensure that your clutch fluid is freshly bled before the pass, tyre pressures lower at the rear, higher at the front; water and oil temperatures are low, air con off, traction control off, a good burnout (trying not to drive through the water box with the front tyres), then a quick ish clutch release with a small amount of wheelspin but not too much as to invoke the torque management programme that is still on even when you have switched the traction control off. Then stamp the throttle in every gear, changing up only when you see the shift up arrow in the HUD. I never powershift my car, which is probably where I lose some time to Ranger. I like to drive hoem again afterwards! In the Z06 I should be in 4th before the finish line, else I am still in the low 12s. Being in 4th across the line means I am in the 11s! Drag racing is all about getting every little detail right - it is surprisingly hard to do this when the weather, track, tyre temperature etc are different every time.
The stock LS2 C6 should run a mid 12 at about 115, some LS3 08 and 09 models have seen passes in the low 12s and even high 11s at about 118/119 if you believe what you see on a forum. If you run a 12.7 I would still be very happy, running just 3 tenths slower is only a tiny mistake in the quarter mile.

How do you find that out driving from Park Lane to Pimlico???Must be one of the quickest out there.
Definitely wasn't the case that Jenkinscomp had no tread on his rear tyres because this was when it had come from Wavendon to have new ones fitted. Didn't you ever drive that car?

And you know what? It gets 31mpg on the motorway, and averages 24. The only fault since I bought it in March 2006 has been a tyre pressure sensor, replaced free under warranty. What a motor.
PS mine has a K&N Intake now, said to add 27bhp flywheel / 15 at the wheels. Only fitted it last year though so not sure if it was on the car when you experienced it...
