I just read the entire tread and I agree, the time slip is really out of whack! Your 1/8 mile speed shows a solid mid 13sec run.
Here's my 12.8sec details, maybe you can compare them to what you ran.
R/T........0.603 (0.500 is perfect at this event)
60'.........2.027
330........5.518
1/8........8.370
MPH......86.69
1000'....10.809
1/4.......12.872
MPH.....108.96
To run a 928 at a low 11secs. it will require somewhere around 650whp, maybe even more and a perfect lauch.
You are definetly running very good times. If the corrections are correct and you are near 13.0, at sea level, then this is very close to a boosted 928. Excellent work!

Good show on your other times but the required "effort" from the motor/drivetrain combo to run in the 11's is WAY WAY beyond any 928 on the road right now.
The effort to go from 13s to 11s is HUGE!!
This is a vid of a 12.6 and 12.7 sec run. The Camero in the run is a set up 11sec car. I have 448RWHP and 422rwtq, and that was how i did against him..
http://media.putfile.com/126-Qtr-mile thanks Henry!
On a some nights ive seen the smoke from burnouts wig out the lights?

right you all are indeed!! did a little research myself and discovered I"d need an aircraft carrier catapult to get near 11sec w/this car!! guess it's a cool slip, kinda like a jesus grill cheese sandwich... ha! man I sure was excited at 1st though!!! damn!
next best run (ie w/out any system failures or wormholes) was:
13.477 @ 102.796 uncorrected (or use .97 on the ET and 1.03 on the mph for sea level adjustment)
rt .278
I1 2.040
I2 5.704
I3 8.692
I4 11.209 @ 82.424 (1/8th)
so my last/infamous run had better mid times consistant w/cooler temps, more aggressive launch... but even the "slower runs" of the night still gained nearly 1/2 sec after installing the LSD, trans tuning and better tires, so it seems the last tuning session was worth it for sure....
bout the only reasonable things left I could do w/out giving up creature comforts would be slicks, NOS(biggest bang/$$ at this point, so to speak ) or perhaps a slightly bigger TB and headers(might sacrafice some low end torque though), maybe fatten out AF a tad (but that'd kill milage and emmissions)... prolly sharktuning to make a hot rod chip and then NOS would be the best choice at this point, so the next tuning session will be interesting for sure...
lights are pretty sensitive and close to the ground - even a rabbit or bird could've tripped it. wind vibration, etc also could do it I suppose... was a 1st for me, never would've guessed it could happen, although our sharks do defy reality/physics at times so I guess it's just part of that shark-parallel universe/wormhole thing, ha!
thx again for catching it!! I'm sure it would've been entertaining to see it printed in excellence after someone caught it there! ha! course, the local track junkies are still talking about it, and no doubt a legend has been born!! the incredible 11 sec NA shark!! ha!

You put "slicks" on it...you're liable to break something. Like a CV joint, or perhaps the flexplate, torque tube bearings, or input shaft to the transaxle. If the car "hooks" hard...the torque has to go someplace, and with the 2:20 ratio and LSD, it will either launch the car like a slingshot, or else break the weakest link in the driveline. Be happy you're car is running so well...and don't take chances that can result in costly driveline damage. If the car isn't totally designed fro handling the stresses of a drag launch, with slicks... odds are you will do OK a time or 2, and then something in the driveline will succumb to the torque and break...Doo be careful

good point jeff, was wondering how much would be too much myself. probably on the edge now, in terms of launch stress as it hardly spins anymore unless I powerbrake it now. and its a pita to mess w/tire changes anyway...
yep, was a fun night indeed! but kinda like waking up married to a troll in vegas the morning after!!! hahahaha!
fwiw, here's what the LACR folks just responded with:

It can happen if lets say a piece of paper or other debris blows by and
trigers the lights.

so its a 6.4 liter and only 360hp, with peak hp around 5500rpm. that torque peak is intereting and big, but i would think you could get it to breathe a little better. maybe you need the GT cams to wake this thing up. i would think that getting near 400rwhp would be not that far out of reach with some components replaced. what about fuel, what did that look like on the dyno?
I think the low 11s is reserved for the fastest cars in the world, like a ferrari F-50, Carerra GT, etc.
It aint going to happen with 360rwhp!! (as you know know)
the engine pics look great on your link. envious!

thx mark! she already has gt cams modified .020" over and 968/bigger valves. it's 360rwhp through a slushbox, so the CHP is pretty decent as is, I think. but I suspect stock airbox and TB could be restrictive, although devek claims the stock Tbody is good to 400rwhp, so I left it alone. I suppose I could mess w/cam timing too...it's got stock specs.
has 10 more rwftlbs torque than mark A's car, which is awesome w/the AT and 2.20 rear end around town/most legalish freeway driving. as you know, usually there's a trade off btween low end grunt and top end hp w/NA stuff (unlike NOS or FI). cant' have it all so ya gotta choose for the type of driving most often done... if it was a 5sp or 5sp track car - I'd have gone to .040" over cams (like mark A, etc), hogged out the ports more, bigger intake, maybe bigger headers, etc.... but those cars idle like crap and dont wake up till 3k rpms or more... on the street w/an AT it'd be a dog light to light, I suspect.
iirc, you and louis ott did some cool airbox mods... I might try that for fun, as it's easy to reverse for smog if it doesn't fly/look OEM or cause any other headaches, like at the car wash

I think Andy has the best 1/8th mile mph so far @ 90mph. I managed 89mph & some change.
Yellow slip was at 7psi, Intercooled. White slip is from my first 12 second pass, 5.8psi, no IC, smaller turbine housing.
