Made my first run at the track yesterday. The weather was right around 50 degrees, track conditions were pretty good. I thought my car was in great running condition until after last nite. I THINK I HAVE THE SLOWEST CAR IN THE NATION FOR MY MODS

Here is my best Run:

RT - .752
60ft - 2.096
330 - 5.823
1/8th - 8.885
MPH - 80.11
1000 - 11.543
1/4 - 13.776
MPH - 101.29

WHAT GIVES!?!?! I was hoping for high 12s not high F***ing 13s.

I was on street tires, and i was beating other LT1s off the line that had stalls and drag radials and they were reeling ME in with a stock motor. I thought it would be the other way around? I'm so mad I'm thinking of selling the damn car.

Please help me troubleshoot some possible problems, thanx guys.

 

after having an lt1, i dont think you have enough mods to get 12's, maybe low-mid 13's, but it does sound like something is wrong. try checking your plugs and or wires...

your time is close your trap speed, and your 60ft is ok, i just think your car isnt giving 100%

i would be troubled too...then again i was in your position and got frustrated and just bought an ls1!

 

yea, well let's theoretically say i don't have $20,000+ to solve this problem. hmmmm

Can i please have some real advice and not the usual "buy an LS1"

 

You need a 3500 or so torque converter to take full advantage of your hot cam and mods. I have a buddy that has the same mods as you and was running 12.7's@107 with a 3500 converter but he had to take it out becasue he bought a cheap torque converter and it took a $hit on him so he put a stock converter in. His times fell to13.6-13.7@101-102mph. He was a second faster with the 3500 stall converter. You should look into a quality higher stall conveter. BTW does it feel like it runs crappy at all or does it feel fine? Who tuned your car? Do you have cats? What was your raceweight?

READ IT AGAIN CHIEF, i gave you a place to start looking at. check plugs and wires...how many miles on them??

and i never said to buy a LS1, i just stated i was in your position...meaning my lt1 never put out what i had hoped with all the stuff done to it, so i gave up and bought a ls1.

you shouldnt read into things, shows very poor social skills.

maybe next time i wont try to help.

btw, not all ls1's cost $20k, something you shouldnt assume

 

A good converter and some sticky tires would help.
There is obviously some more mph left in your car too.
Check all the tune up stuff and then decide on wheter you trust the programming in the car.
I have a friends car that is like yours. It just seems like a pig. Musta been built on a friday.

 

To be honest, i noticed a bigger difference in performance when my catback was installed over the cam, headers and gears. But i did put in new plugs, wires, distributer, and coil when i did all this to ensure my car would run well. My car was tuned by www.bvperformance.com which i'm a little sketchy on the results. I do have one stock cat still on there. I'm not sure on my racewieght either.

Droopy, i know how to read, if u checked the sig u would see i replaced plugs and wires. And don't talk down to me, u don't know me or my "social skills" thanx anyways for the advice.

 

What are your shift points? Short shifting a Hot cam car will kill your runs.

 

I have been debating for a long time now on whether i want to invest in a stall. If i buy one, it will be a Vigilante 2800. But don't torque converters only help u off the line? I was also thinking of getting some drag radials, but i have a bad 3.73 gear in my rear end and i'm afraid it my bust on a dead hook. I figure 2.0s are pretty good 60s for my car on dunlop comp 5000s street tires. but my trap speed and time are pathetic, I see STOCK LT1s running those numbers. Could I be running out of fuel at the high RPMs?

 

My car shifts at about 6200 RPM, I had it shifting around 6500 RPM before, but the power curve of the cam was falling off at that high of an RPM and the car was falling on its face.

 

First get rid of that stock cat and put a pipe in place of it. Next, make sure you are shifting the car as said above...a hotcam will like to be shifted at ~6400-6500rpm's. You might want to check out www.pcmforless.com for a tune on your car...I hear they are pretty good and know some people with good results from them. You should look into a conveter and some tires and you should easily be in the mid 12's @109-110 in good weather with good traction depending on raceweight.

wasnt talking down to you...was wondering why you read into things, and why you thought checking plugs and wires wasnt good advice.

your sig told me the plugs and wires you have, but i didnt read in there how old they were, my bad...i guess

i would check tuning...been there and done that too....not a good story either

 

I'm just so confused and pissed I don't even know where to start. I want to get a laptop and get LT1 edit and scan tools, but if the programming isn't the problem then I can't afford to fix the other possible problems. Where do u all think i should start?

 

Was the car actually dyno tuned or did BV just do a file for it?
If it was dyno tuned what did it make? Got graphs?
If you're really unsure of the programming, shoot me an e-mail.
Maybe I can make you an offer you can't refuse.

 

i am almost convinced that your tune is the issue w/ your car along w/ your shift points which will be fixed in a proper tune.. get in touch w/ brian @pcm for less and he'll hook you up.. maybe you can look for someone in your area who's familiar w/ a program like LT1edit or tunercat and can help you out getting your car to run right.. Tuning a cam car isn't a plug and play issue.. And not every car react's to the same tune the same way.. i'm sure many other's will agree.. Good luck w/ it and keep us informed..
