Tire roasting in an LT4
Just curious, do you guys with LT 4's have problems roasting the tires with the ASR off? I put my LT4 into first, let the clutch out and at about 5 MPH floored it and no tire roasting at all, ASR off. Should my car have more power than that? It just took off. I do have an intake leak where oil is coming out from the front and rear of the intake. Is that enough to to rob a lot of power from the engine? I just picked the car up Tuesday and have only driven about 40 miles. I did notice when I got home that all of the tires were about 10 pounds low on air... could this be it?

Re: Tire roasting in an LT4 (Hamert)
I should also mention that I haven't driven the car since putting the air in the tires as it snowed the day after I picked it up, and my drive way is all ice now. I'm afraid if I take it out I won't be able to get it back in the garage... :mad

Re: Tire roasting in an LT4 (Hamert)
What size tires do you have on the back of your LT4? A lot of your traction will depend on the tires and pressure that you have on the back. I can tell you one thing, your back tires will not last over 20,000 miles though and thats will easy driving too. I don't drag or autocross mine, its a daily driver that I drive back and forth to work everyday. The longest I have had a set of back tires last me is around 20,000 and they were as slick as can be when I finally took them off. :yesnod:

Re: Tire roasting in an LT4 (Hamert)
I have BFG KDWS tires and 4.10 rear end LT4 and on "good" pavement I can floor it at 5mph with the clutch out and maintain traction. Poor pavement conditions can change that, I remember once at about 30mph I hit some loose dirt on pavement & the car totally lost traction.
On the other hand, rev it a little & dump the clutch and you can roast the tires as much as you choose!!

Re: Tire roasting in an LT4 (LT4BUD)
I can floor it in 2nd (without popping the clutch) and spin the tires on any pavement. That does not mean to much. Too many aother factors involved. You need to take it to the track or get a dyno done to really know if you car has good HP.

Re: Tire roasting in an LT4 (Hamert)
Hmmm, I can crawl at 5 mph in my Honda, floor it, and light them up! That must mean my Honda has more power than your LT4? And I don't even have any stickers on it.
Not really, there are some roads with such great traction that I can't burn out in the LT1 even when I drop the clutch at 3 grand. A lot of real roads give much better traction than a track. With my old 69 Camaro SS and 4.10 rear I had to launch at the track in 2nd gear with street tires, but on any real road it would blast off in 1st gear, hooking up immediately.

Re: Tire roasting in an LT4 (Hamert)
on any normal city street, with 4.10 gears you should break the tires loose easily, especially this time of year with cold asphalt.
Is your clutch solid?
My stock LT-1 with 373s will do it from 5 mph roll easily.
You say you just picked the car up??
Did you just buy it? From a dealer?
If so, take it back now and deal with that oil leak!
To have a garage fix that is big $ :eek:

Re: Tire roasting in an LT4 (Hamert)
My LT1 six speed is the same way, if I let the clutch out and roll in idle and punch it, the car will just lift and take off, just like it's supposed to. Now if you dump the clutch and floor it, you'll be smoking them like crazy and bouncing off the rev limiter before you know it.
Now in my LT1 automatic, like Phil, I can smoke them from a standstill or from a slow roll.
Remember, tire spin on a launch is not good for racing, you want traction.

Re: Tire roasting in an LT4 (Hamert)
I would doubt the cause of the oil leak would prevent you from lighting up the tires, unless your gasket is very, very bad. What size tires do you have? 315's will definetly bite better than the 275's. I can break away my tires at 5mph but as stated before, that doesn't mean too much. Take it to a dyno, and that should get you started in the right direction if something is wrong.

Re: Tire roasting in an LT4 (Hamert)
As others mentioned, it depends on the road mostly. Tires as well. On the street tires, on clean asphaly a 5MPH roll won't let me turn the tires over - frankly, the engine just isn't really in the power band yet. Get it up in the 4-6k RPM range though in 1st gear and on the right road it'll light 'em up. Then again, cold (and old!) autocross tires will spin just about any time until they come up to speed.
If you're worried, at least take it to the track and see what kind of times you can turn.

Re: Tire roasting in an LT4 (all4c4lt4)
I'm guessing since I do not have a 6speed, that your car is just a hair over idle speed (in RPM) when doing 5MPH with clutch out. I wouldn't think your car would have the power at such a low RPM to light the tires. You have not hit the power RPM range yet plus all the other facters. Remember your car is not putting out that 330 HP at all times.

Re: Tire roasting in an LT4 (88_vette)
Thanks for the responses guys. The rear tires are 285/40 Goodyears. Don't get me wrong here, I don't want to be roasting $400 worth of tires everytime I take off, I was just wondering what your guys cars did in the same situation. I would much rather have it hook up and go. As far as the oil leak, yes I just picked it up, yes I got it from a dealer, but I am going to fix it myself. I got the car at a very good price and part of that was because it was sold "as-is". The dealer was asking 24k and I got it for 17k. I'm not too worried about doing it myself as I just did the heads on my ex-gf's vette a few months ago so I am pretty familiar with the procedure.

Re: Tire roasting in an LT4 (Hamert)
The other reason for the post was before I got the car I was reading a review on Edmunds and they said that they were lighting up the tires all the time at stop lights even with the ASR on... :confused: It just didn't sound right to me, or maybe they were dumping the clutch at every stop light, who knows?

Re: Tire roasting in an LT4 (Hamert)
I've had both LT4 and Lt1 6spds with same Comp TAs. Neither one are much off the line. Lt1 noticeably stronger below 2000rpm, about same to 5400, Lt4 makes up for it 5400 to 6000. Also remember suspensions got softer in late C4s, even Z51=better traction.
Just curious, do you guys with LT 4's have problems roasting the tires with the ASR off? I put my LT4 into first, let the clutch out and at about 5 MPH floored it and no tire roasting at all, ASR off. Should my car have more power than that? It just took off.

Re: Tire roasting in an LT4 (Hamert)
Well.... I have L98 6-speed.... With the clutch all the way out.... i cant go less the 7 mph wih out boggin down the motor. I have 3.45s.... But I will still smoke em, if I stomp it from there, It will start to take off, then when the RPMs get up in its power range, they lose traction and th car starts wantin to go sideway

Re: Tire roasting in an LT4 (Hamert)
With my lt4 it really depends on the road and tire temp. Sometimes I can burn the 315's with ease and other times they hook up... At my 1st outing to the track 2 days ago I got the worst traction ever. Had to let off in 1st, got sideways in 2nd and spun in 3rd across the line (1/8th). Could have been driving it a little harder and the adrenalin... Still was surprised to spin in 3rd... :cheers:
