LS1 6sp + bolt-ons = 11's
 
Went to atco a few weeks ago and had CaptHuff lend me his drag pack. I ran on Toyo drag radials and GTO spares. When I first got there I had a loose plug and the car was acting strange. Sat around for an hour, maybe two, while people made pass after pass. Finally got everything together and told Pete to get a video. First pass did a nice burnout, launched to a 1.74 60' and had a really clean pass. Got the slip, 11.80@118mph. Got back to the gate and Pete and Marc are nowhere to be found. Went back into the lanes and made a pass, 1.77 60' and missed third. I let out, put the car into fourth, cruised, shifted into 5th around 4500rpm, and eased through the traps. Coasted to a 14.2 at 90 some mph and still beat a honda by about 20 car lengths. Found pete and he asked me what happened. I asked if he saw my first pass and he said no.. hahaha. Anyways I made the one botched pass at low 14's, two passes in the 11.90's, and two passes in the 11.80's. Track prep was OK. Heres the breakdown.

RT .966
60' 1.744
330' 4.975
1/8 7.622
MPH 92.70
1000 9.891
1/4 11.806
MPH 117.91


Mods: Vararam, ported stock TB, LS6 intake, XSPower headers w/ORX, Granatelli catback, RPM Stage IV trans, Spec Twin clutch, RPM Stage II rear w/3.90 gears, ECS brace, dyno tuning.

Here is the video.

Wow, that mph is impressive for stock heads and cam. Shows what a Vette can do with a proper launch. Are you running c5z gearing in that trans or m6?

slowtealz28 Apr 3, 2011 10:58 AM

no stock coupe gearing in the trans

desertLS1 Apr 3, 2011 11:38 AM

hmmmm impressive.

dumb ass question, would putting the headlights down help? LOL

slowtealz28 Apr 5, 2011 09:45 PM

Yea I suppose, I always run with them down but forgot to do it on that pass bc I was in a rush.

No love for the little LS1 that could? I think people are forgetting the car is just bolt-ons with stock 853 heads.

Sweet #s for sure. Love the sound of bangin' gears !!!!

marc97taws6 Apr 6, 2011 08:51 PM

Impressive for sure! :thumb:

10's are around the corner. Might be ordering a blower this week.

very nice. did it make a big feel in seat of the pants when you put on headers?

demarco313 Apr 11, 2011 04:58 PM

Nice video and shifting man.. What was your launch technique? What rpm did u launch at? Slip the clutch or what?

Not really. I didn't get a tune right away. Went to the track and ran the same times as pre-headers. Got a tune and dropped 2-3 tenths and gained 4mph. When I took the headers off, sold them, and put the stock manifolds on while waiting for my new headers, the car felt like an absolute TURD. So i'd say yeah, if you do headers/tune at the same time you will DEFINITELY notice it. The first mods that should be done with these cars is vararam/headers/tune. Easy 6 tenth drop and 5-6mph gain. Gears are hands down the biggest SOTP improvement. It felt like a brand new car when I got it back. I bet if I drove a car with identical mods/times but with stock gears, it would feel slower than my car.

Launch rpm was between 4000 and 4500 rpm. I basically just slipped the spec twin as much as it would let me and get right onto the gas HARD to prevent any bogging. My last run in the video you can hear a slight bog on the launch. I'm very surprised the car still went 11's on that run. When I had stock gears, if I bogged, the pass was always 3-5 tenths slower. With the 3.90's, the car can pick back up into the powerband much quicker, making for less of a difference.

Cool, I am running 4.10's and I have been thinking about a blower at some point in the future. Which kit are you thinking of running

slowtealz28 Apr 17, 2011 06:39 PM

I am going to run the ECS Novi along with a blower cam. Should make 550rwhp on 7-8lbs safely.

Mike Morris Apr 20, 2011 10:25 PM

Nice job and killer MPH

tits dude....tits

madmatt9471 Apr 21, 2011 10:26 AM

That's pretty impressive - nice run!:D

Thanks,matt

T-REZ Apr 21, 2011 10:55 AM

what kinda power did your car put down

slowtealz28 Apr 22, 2011 10:14 AM

Car only put down 331/343

evo2ls1 Apr 22, 2011 10:26 PM

Cool, well I am throwing the idea of a blower around, but havent decided yet, I am concerned about the 4.10's and trapping to high and running the motor too high on the big end, what gears are you planning on running
