Was cruising down santa teresa around 11 at night, saw this black 2k lt1 firebird. So i thought to myself what the hell, the funny part was we were going 40 and nietherof us dropped it into second but gunned it from third, anyway as you would think he pulled away from me decently by 70 he was about 1car and a half ahead. owell at least i tried haha.

2000 LT1? must've downgraded lol

TLS_Addict

His LS1 not LT1 would rip you a new one. If your both stock.

The last STOCK IROC 5.7 I ran with my GTO wasnt even close. From 35-75 I was 3 cars ahead.

Run a top shape 89 formula 350 and see what happens.


I have a 383 in my 89, if i ran from 40 in third i would not move verry fast due to 2.73 rear gear, but at 80 or so running thru the gears, i tear them up badly. Now a 305 is simply screwed in stock or even mildly modded by the LSx.

The tpi will compete or beat lt's or ls's down low. especially in light to light type races. but after that they are toast.

CashMunson

yep, it's all about where you race them. from a roll the ls1 has it, from a dig the tpi car would crush both of them light to light.

it is truly fun stop light racing ls/lt cars with bad drivers makes me and my 220 hp motor feel good lol.

rik89gta

Lol! I raced my buddies 2004 GTO at the track and I would pull on him until the 1/8th. After that He'd come flying by me near the end of the track. He was pulling 13.5's at 105 compared to my 14.10's.... Definitely fun races!

rideon1200

Must REALLY be a bad driver if you can beat them with 220hp. Stock on a LS1 is 340 add some minor bolt on mods and ?. Whats hell if you are really tear it up and a women in a caravan passes you!LOL Point is, maybe you are the only one racing light to light. Because there is no way with 220HP you will keep up with a LS1 Firebird or Formula unless it is on the back of a tow truck.

CashMunson

iTrader: (1)

you're saying a stock ls1 puts 340 to the tires?

Ed Z28 350

Seems too high. My 01 LS1 with a lid put 329.9 to the wheels.

fly89gta

Read what he said again. He said stop light to stop light.

CashMunson

iTrader: (1)

that # is definitely too high. i've seen tons of ls1 cars dyno'd at our local shop. the highest i've seen out of a stock ls1 is 320 or so from the 02 6 speed cars. the normal for an auto is right around 305-310 and for a stick is right around 312-315. ofcourse it's very rare to see one that doesn't atleast have a lid.

Cali Z

no, he is saying flywheel. Why would you automatically think he meant rear wheel?

CashMunson

iTrader: (1)

why would you automatically assume he meant flywheel? he never answered the question. either way the # is wrong. it's too high for rwhp, and too low for flywheel hp. :shrug:

19redbird89

I lov ethese LS1 threads. From a a stop light they are saying that a nice well kept 350 can pull them for about 1/8th of a mile and I agree. If you have some goodies on the motor you have a good chance of hangin in til the end but it all depends on your top end power. I have to say Third gens are a beast out of the hole. (if you can hook)

25thmustang

Well from a roll even a top running L98 will get walked handily by an LS1. From a dig, sure but it appears your talking roll races here and the LS1 wouldn't be worried about even the best running stock L98. Not sure what your stroker motor has to do with the comparison either, but 2.73s will kill any car really.

From a dig torque and more important traction play huge rolls. Roll races with TPI isn't the smartest, especially when talking about LS1 cars in the other lane, but from a dig there's a chance! Now a good driver in the LS1 who can walk it out of the hole, you might be done from the get go!

Cali Z

because 340 is fairly close to 345, which is the average flywheel horsepower for an ls1 without any slp options. I can see where your going though, alot of the 6spd's and slp lid/catback cars are what we usually hear about, and are the 320-330 rwhp cars that are 370-380 flywheel. My car was just a run of the mill 98 ls1 an auto at that and made 300 to the ground, which is 350 flywheel. Sorry about the misunderstanding, it's just these cars vary so much 30-40 hp difference from car to car, being factory.

TTA 1387

I always find it funny that TPI owners think they own LS1 or even LT1 owners to the 1/8. How is it that a car that went 0-60 in about 6 seconds is faster than a car that does it under 6 seconds? Both the LT1 and LS1 did 0-60 under 6 seconds, yet TPI guys always claim their slower cars are so much faster. I don't get it.

Even my heavy pig of a GTO goes under 6 seconds to 60mph when it was stock. Defies logic....

CashMunson

iTrader: (1)

yeah i know what you mean. i just wanted to know why he threw 340 out there, and what he actually meant by it. i've seen many ls1 auto cars bone stock put 305 or so to the tires. it really depends on the year of the car and the tranny.

CashMunson

iTrader: (1)

maybe for you. all it takes is a decent driver to get a tpi car out of the hole very quickly with all the torque it makes. and your average ls1 owner will rip into it and sit there spinning while the tpi car is driving away...

TTA 1387

That's the thing. Everybody here that TPI's will out torque an LT1 or LS1. That's just wrong. Its easier to launch an LT1 or LS1 than a TPI. The TPI has more torque at idle and off idle but then dies off fairly quickly.

Its rather easy to get either an LT1 or LS1 in sub 2.0 short times bone stock. Not saying a TPI can't do it either but its a lot easier for the others. Hence the better 0-60 times for them also.

PHAT89TA

guys let put up dyno readings on l98 and ls1 motors. here my dyno numbers on my 02 ws6 m6. all stock except for slp lid, k&n filter through clogged cats.

25thmustang

So your comparing a bad driver in an LS1 to a good driver in a TPI? The more torque and peakier (yeah I know it's not a word) it is, the harder it will be to launch.

Coming from someone who can launch a car decently (consistent mid 1.9s with a 1.91 best on a lowered car on 18" street radials), the LS1 and LT1 with a good driver should beat an L98 or TPI car out of the hole when traction is had.

CashMunson

iTrader: (1)

maybe you have good ls1 drivers where you live. we have few here. i've sat in the tower at our local track, and watched hundreds of ls1 drivers launch like crap. everytime a ws6 ta lines up, i watch a 5k dump on street tires that leads to spinning through 1st and 2nd, and a 2.4 60 ft time. notice you're saying... when traction is had.

DIGGLER

iTrader: (1)

the main thing about the tpi cars is torque.... so thats what the tpi owners brag about. lol
huge torque down low doesnt mean it pulls faster than an LT1/LS1 i wouldnt think, since both of those cars are mostly traction limited down low from the get-go. i'd say that makes the torque arguement kinda moot. its all about hooking up.
my stock (with cai and exhaust) '93 Z28 6 speed went 8.90's@81 with a 2.0x 60'.
my stock '99 SS 6 speed went 8.59@84 with a 1.9x 60'.
how about you tpi guys?

Cali Z

ya I feel this argument also has little backbone to it also. Most bolt-on tpi cars are in the low 14's/high 13s at sacramento raceway and even if they drove me out of the hole I was ahead of them by the middle of 2nd gear on the 12.9 passes, which is well before the 1/8 mile.

25thmustang

I don't see how you can generalize and compare a bad LS1 driver vs a good TPI driver.

Take your guy running 2.4 60's in his LS1. When you stick him in a TPI car with more grunt down low what do you think he is going to do? NOW take a guy who can nab a 1.9 in a TPI car and stick him in an LS1. Same 60' from a car that will haul the mail up top vs a car that gets to 60-70 and starts huffing.

Launching ANY street tired V8 at 5000 RPM is going to yield those results. But to say TPI's will stop light to stop light beat an LS1 because the LS1 driver is going to suck and the TPI driver wont is just a terrible way to make a claim.

To compare two cars with two unknown drivers (which is where the LS1 vs TPI debate has to be taken from) you CANNOT figure the TPI driver to be better than the LS1 driver, and if so what is your basis other than a generalization of people in your area???

8.7@79 1.9 60' with stock tpi.Not up to par with your SS but with better gears,sticky tires and stall I may get close.However thats not stock and you`d still own me top end,TPI is tough to launch well.Took me forever to get low 2.x 60'or better.

TTA 1387

Here's the best the goat did when it was stock. Took 4 trips to the track to figure out how to launch it. The very first pass down the track was a wheel hopping 13.6 on a 2.1. That was with about 600 miles on it. The 4th trip had about 1000 miles on it.

8.568@83.23 on a 1.956 short time. Ended up running 13.252. Definitely not the quickest stock '04 but it was the best I could do before the mods started happening.

I have only tried an LS1 F-Body once. Took a brand new 98 WS6 down the track and it ran 13.3 back in 98. It was a completely different feel to my LT1 WS6. If I would have had a couple more tries at it, I'm sure I could have gotten at least a 13.1 out of it.

3rd gens are a good 500lbs less, if not more, than the goat. So it takes some power to get that thing out of the hole. An LT1/LS1 F-Body is easier to launch and should run quicker all things being equal.

Good lord.

LSx > LTx > L98 (assuming bone stock)

There, I said it. Now you can all stop arguing

25thmustang

Not sure if I am missing something but your car is not stock. An LT1 or LS1 with the bolt ons and a cam like you have would be deep 12s cars?

DIGGLER

iTrader: (1)

that doesnt sound anything near stock to me, with all that stuff in your sig.

here's another one for thought.... a buddies car, '97 t/a full weight with nothing done other than a th350/3200 converter, catback, and drag radials went 8.0's at 85ish. thats with stock manifolds even. lol
----------
buddy of mine just ran a 12.7x@109 with a 1.9x 60' this past weekend. '04 gto with 19" rims on it and street tires. full weight. headers/exhaust, cai, fast intake, and a little tuning i think.

Shadygrady

iTrader: (3)

Well the tpi is stock and engine mods are mostly gm production parts,but I get your point.Stock l98 cant really compete with the newer series engines.I was really just replying to the how bout you tpi guys comment cause there are some respectable tpi powered cars out there.

25thmustang

Were they production parts off yor car? If not, the point is mute.
