I took my Camaro to the local 1/8th today for the first time

The mods are in my sig, the car is stock weight minus the front sway bar and was running a full tank of gas

Stock 10 bolt running 3.23s, MT ET streets @ 18psi, hazing them in the waterbox

Run #1
2.4530 60' leaving at 2000 rpm smoking the tires down the track
9.080 @86.84mph


Run #2
2.2140 60' leaving at 1500rpm- car almost sideways at the 330' mark
8.9420 @ 87.04


Run #3,
1.8150 60' leaving at idle
7.8319 @ 89.46


Run #4
1.9080 60' leaving at idle
7.8552 @ 90.49 - I put the car into 3rd for this run, the other three were in OD but I noticed it shifting just before the traps

I am a pretty poor driver at the track and I am thinking if a 1.5-1.6 60' could be obtained it could run bottom 7s

You need to do a bigger burnout with ET Streets , like 7- 8sec and past the waterbox not in it. Also try 14 or 15psi in the tires

Like stated above, drop the pressure, do a John Force impression, then foot brake it up on the convertor till it wants to push past the brakes. That should get you your 1.5-1.6's. Your MPH is not good for low 7's. Maybe 7.5 at best with 90mph.

yeah but I ran a 7.8 on a 1.9 60'

if I cut 1.5s that should be worth 7.4 at a minium, I would think more like .6 tenths which would be a 7.2

if you can run 7.20@90 with a 1.5x 60ft then you must be on the brakes before the traps atleast not at WOT going across the stripe, IMO a car that traps 90mph with a 1.5x 60ft is only going to see 7.7x

Maybee the MPH clocks are off on your runs

I wouldn't drop the tire pressure much, maybe a bit more burnout but remember drag radials (if you are running et street radials) don't like a huge burnout. I do a 2-3 second burnout and get 1.51 60 foots in the Nova on a 275/60/15.

90 mph unless it's coming with a mid-low 1.5x 60 foot time will get you 7.3-7.4. My car cut mid 1.5x 60 foots and goes 7.30s at 92-93 mph dead hooking.

Well lets see my 98 Formula with a totally stock 92K mile engine with LS1 intake and only headers, stall convert, ET Streets weighing 3,665 lbs. went the following 1st run 1.565 60 ft, 4.829 330 ft, 7.593 ET @ 88.68 MPH. Second run 1.54 60 ft, 4.786 330 ft, 7.533 ET @ 89.14 MPH.

He has a built engine, if my car can manage 7.50's with a stock engine with only headers I think with time he should be able to go faster!

What I am saying is its running 7.8s with a 1.9 60'

if I shave 4 tenths off my 60', how would that only equal 1 tenth in the 1/8th??

I am sure I can get the car to trap higher, the last run where I trapped 90.49 was my only run in 3rd vs OD

It also was about 80 degrees out , full tank of gas and the track wasnt prepped very well

I am hoping it can trap 93 or so in the 1/8th

Man i would have loved to have that car My **** is slow as hell to that, When we where stock with your mods we couldnt run near that, It took a small cam (224) and a **** set of heads to run 7.5x but we did it at 92-94mph
For a 3665lb car on a stock motor to 60ft 1.5x is very impressive, 88mph sound about right for a stock motor with headers and converter my bone stock the way it came from the factory TA with a converter ran 84mph

As said in my last post its my OPINION, My shop has built several LS1 cars from mild to wild and everyone of are cars have givin very simular results, every stock car we have tunes has ran from 8.7-9.0 stock every stock car with bolt on and a converter has ran between 7.7-7.9 in the 88-90mph range, every small h/c car has ran 7.4-7.6 in the 92-94mph range, bigger H/C cars have ran 7.2 in the 95-96 range

This car that ran 7.50@88 with the 1.5x 60ft what did it run in the 1/4 if you dont mind me asking

ChevPower

iTrader: (8)

I'm not saying it will only make .1 with a .4 better 60ft I'm just saying IMO something doesnt add up Every car we have ever delt with over the years couldnt get even close to 7.2x with a 90mph trap speed With your mods I'mm sure you can get there i'm just curiuos to why your trap speed is so low that all

98LS1Formula

iTrader: (23)

I dont know honestly, it was only 86mph on the first run and went up with every run there after

I only made 4 passes with it

I would guess if I could get the 60' down to 1.5 that I would trap 94 or so

The car was spinning the tires down the track even on the last run and it seemed like it was still shifting about 50' or so before the beams...........

Also the track I ran at goes uphill slightly towards the end and I have heard many people say the track is .1-.2 tenths slower than most other 1/8th mile tracks.................

iTrader: (8)

Are you spinning beyond the 60ft mark?

98LS1Formula

iTrader: (23)

yeah, on a few runs it felt like it was still spinning around the 330' mark or so

here is a vid of run #2- if you look close you can see tire smoke pouring off my car and hear where I got out of it to get it straight

and here is run #3- I am pissed the camera guy was asleep because it was a much better run than #2

Thanks for the props! My car even had an LS1 intake on it. Here is the information you requested.

On the pass that I posted as the second run where the car ran 7.533 at 89.14 it completed the run with the following times and MPH, 1,000 ft 9.919 and 1/4 11.944 ET at 111.17 MPH. The first pass I did not run it all the way through the 1/4 mile it was my first time down that track.

That was in late 2006 in early 2007, I installed the 346 CI pump gas engine with heads and cam and switched to ET Drags and 4:10 gears due to the ability to shift at higher RPM's. I also got the car down to 3,430 lbs. and went back to the same track fall of 2007 and the car went 1.417 60ft, 330 ft 4.296, 1/8 6.777 ET at 98.86 MPH, 1,000 ft 8.926, 1/4 10.752 ET at 123.10 MPH. I backed that run up with a 1.416 60 ft, 4.320 330 ft, 6.790 ET at 99.27 MPH 1/8 mile, 8.934 1,000 ft, 10.756 ET at 123.29 MPH 1/4 mile. I also had a 1.401 60 ft but messed up the shift oh well next time.

I'm calling bs. If it's not bs you have yourself a factory freak

N2RACINGLS1's

iTrader: (2)

I would not call a tired old 92K mile engine a factory freak. After tunning from adding the headers it put down 329 HP and 350 TQ to the wheels. Come to think about it did run pretty good for never taking the valve covers off of it. When I got the car it did not have one and mean not one performance mod on it.

Maybe you should just call it putting the correct parts where they need to go!

Dont get hung up on what other cars run. If they dont run that at your track on same day as you then its just noise.

Your speed looks weird. Usually when you spin your mph is a couple mph faster and yours is backward.

I could see you dead hooking at a points night on a well prepped track with a 2-3sec burnout on MT radials but IMO that does not work on a TnT night with a marginal track. When I do a 7-8sec burnout I can usually get good 60's even at Orlando. I have never hooked on a small burnout with MT radials on a TnT night. I will admit on points nights I dont do as much of a burnout and it still hooks but thats when there is 200 slick tire cars putting rubber down all night.
