My bud has a 93 TA with Longtube headers, K&N cai, highflow cat, cat back exaust, stock 3:23 gears, built trans auto with 3200 stall, pcmforless tuning and a electric water pump. My car in sig.

We were dead even on every race from a roll @ 20 40 60 up to 100. We will race again next time from a dig. He and I both were very surprised. Him more than me.LOL .

I told him once he beats my ss than he can have a crack at my TA. He better start heavy modding.

Of course I will buying the sydyne header this week so he better watch out.

Wow, thats sad for him. Really sad. My buddies Z28 with the same mods minus the WP, convertor, and tuning could walk an SS from a roll. He should get that tuning checked out on a dyno, cause something aint right.

What year and what do you have done to your nice car?

 

thats not completely true... my friend has a 95 z28(lt1) with full exhaust,cai, and gears and i keep up with him from a roll because lt1 suck at top end hp.... no i am not being bias either.... he although i can keep up with him at a roll he can run 13.9's at the track all day long.

 

Weel I think my buddy has a freak car anyways. Hes run a best of 13.0@102 with just the mods he has, whereas most other LT1 cars would be stuck in the mid 13's. All depends on the car, but I still think this particular LT1 should have had JAESS from a roll. That guy must have a dud for an LT1 I guess.

 

LT1's with those mods are mid to high 13 second cars with a good driver in perfect conditions.

Those simple mods don't put them into LS1 territory. Your friend has more mods or mods he don't know about GTPsRule.

 

He bought the car in '03 with 36xxx miles on it, box stock all the way down to the paper air filter. Only performance option it has is the 3.23's with LSD. All hes done to it are Pacesetter LT's, SLP catback, and a Moroso CAI. It doesnt even have any tuning done, and it has a stock convertor and tranny. Its a 12 second car with DR's. As I said, hes got a freak LT1 that runs stronger than others with the same mods. Some respond well to mods, some dont. Just like LS1's. I know the car, I've worked on it and driven it. Hell I got it in the 13's before he even knew how to launch it good

 

that says it all right there.... they got a bad ass low-end and once their rolling they struggle pretty bad. it's a fast time, but slow trap. cobalts are so-so on the bottom but they scream from a roll

 

I just don't see that LT1 getting into 12s nor do I see it running 13.0 without a Stall LTs, CAI and C/B doesn't cut nearly a full second, sorry but that is how I see it.

 

Even so hes got atleast 4mph on an SS in the 1/4, so it would be a good race from 100 up. But thats this particular car. Maybe the car that JAESS raced isnt as fast as the one Im talking about. As I said 2 times before, they all differ.
Well Im just telling you how I saw it for my own two eyes. I wouldnt come on here and lie about a car I dont even own I dont know whats so hard to understand. The car makes sick torque, got good traction, and got off the line pretty good. With slicks or DR's he'd be able to get off the line even better (flooring instead of pedaling) and could more than likely grab 12's with a trap still around 100.

 

I just can't see it happening without a stall. A4 doesn't lauch strong without it. LS1 have lot more torque than LT1 but without a stall, it can't even cut 2.0 seconds in 60'. M6 with a decent driver cuts much better short time than A4 (without a decent sized stall). Those three mods you've listed isn't going to cut nearly a full second from a 14 second car.

I've been around long time around many, many both slow and fast F-Body to be skeptical of your claim.

I'd insterested in seeing his time sheet.

 

I can also say LT1s suck ass from a roll. My bro has a bone stock 94 camaro Z28. From a roll, we are side-by-side and my cobalt begins to pull as the mph goes up. But from a dig, he kills me at first, then i slowly gain. His best 1/4 ET is a 14.39 & 96. mine is a 14.5 & 98.

 

I found when I was stock(ish) that about 4k was the sweet spot for racing from a roll with my Z28. They dont really suck ass from a roll (well a little), but just like the TPI cars, they run out of breath but dont fall on their face like the TPI's do. Looks like from that trap that your brother's down on about 2-3mph. I remember hitting 14.0@99 w/ a 2.2 60' stock down to the paper filter in the airbox. Something might be up.

 

His is an A4, thats the difference.

 

Hes working on finding them. I was there for them and I did see the slips with my own two eyes, and I believe I even watched the run too. Believe me, I didnt think it was possible either, nor did a local LT1 expert. He was more amazed than anyone. Mind you he did cut a low 1.9x or high 1.8x 60', which helped immensly. His car makes real good torque, thats about all I can say.
And please, any LT1 can cut a 2.0 without a stall. Hell my 91 RS with the 305 A4 cut a 2.18 and that was with me feathering to prevent wheelspin. LT1's make alot of torque, theyre right up there with the LS's. They just dont make the horsepower the LS motors can.

 

Ok alittle lt1 info. I bought my 95TA convertible brand new so I have alot of time slips for it. Bone stock best time without anything done in great weather at the best track atco in new jersey it went 13.992@ 98 1.98 60'. That was bone stock convertible. Then with a cai and smaller crank pully and hypertec it went 13.79.
next with a cat back and shorty headers and 3:73s 13.6.
Then went with long tubes high flow cats 3000 stall and all the boltons bigger throttle body every bolton I could do the car went 13.0 @ 104 with a 1.72 60'.
now with everything above and cam heads and a 3600 stall the car goes 12.20's @ 110 with high 1.6 60' times. I also ran a best of 11.3 @ 121 with a 1.56 60 with a 125 shot. I'm shooting for tens next time out. All this with a stock short block. My goal is to run tens with the stock short block. Well LT1's get a bad rap because alot of people don't take care of them or they've been beat to hell. Back when they first came out alot of them were running high 13s bone stock with good drivers. My car also weighs 4000 pound track ready. 12bolt double diamond frame connectors lowering springs etc,etc,
Joe
p.s. I love my lt1.

p.s.2 My friends lt1 has 170000 miles on it so that might explain why it's not 100%

 

Hell yeah. Me too. So much I'd take it over an LS1 anyday. I figure that mine was beat to hell due to the previous owner putting 7k miles on my car the 3 months before I bought it but it behaved like a typical LT1 off the showroom floor and I've had few problems that didnt have something to do with my modifications. Its treated me well these past 3 years and I'm sure it will until the day I die because I'll be the last owner of the car.

 

I dont see how you guys say LT1's suck at top end...ya know, where your car rocks... That 13.0@102...yeah thats a pretty damn good time for a mild bolton LT1, but i dont see what sucks so bad about its trap...its still much higher than many of you guy's cobaltSS's... A buddy of mine ran a 13.8@103 in his BONE STOCK 97 LT1 SS M6. I guarantee that car will also break 150. Thats not too shabby by my standards. And guys, hate to break it to ya, but the 'lt1 sucks top end' is a lame and completely untrue arguement.

Oh, btw, if any of you guys would like to purchase a 97 lt1 SS m6, it is for sale in good 'ole Arlington Texas. Brad's tryin to get rid of it. (its red, pretty clean, could use some interior love, but motor is in great condition.)

 

Yes, LT1 top end does suck. Drive a LS1 once.

And 102 is only 1-2mph better than a SS/SC but neither a LT1 or SS/SC is a constant 100+mph car in the 1/4 avearge for both is 95-98mph.

LT1's are just like the SOHC 4.6 they in stock form they die off at higher RPM's. Even the LT4 is a low end monster.

 

I would say that 102 is atleast 4mph better than the SS/SC, based on what I've seen here and over on .com. I think the average for an LT1 is closer to 100(atleast with the M6) and an SS is right around where you said, 95-98.
And I was told by my buddy that he trapped 108 and not 102, but I dont remember it being that high. Im waiting for him to find his slips to verify it.

 

ive driven a stock ls1, and a non-stock ls1, and i will take the non-stock 856rwhp twin turbo SS over the stock ls1 as far as top end is concerned thank you very much...

 

When I clicked Submit Reply on that last one I could almost hear it go over Chadder's head.

What I was saying GTPsRule is that on average no stock LT1 is trapping 100mph M6 or Auto. The average is in the 95-98mph category.

Keep in mind also that the is less difference in M6 LT1's vs Auto LT1's unlike the LS1.

I have had two LT1's and 100mph + was a rare occurance.

 

i know what you were saying, i was replying to the "drive an ls1 once" thing...

i know i cant prove what i said, but what i said was the truth bro...ive seen more than one stock lt1 trap over 100.

 

Most do or are very close. hell I did. Lt1's trapping under 97 either have something wrong or the old driver mod needs to be done.

 

My dad's got a 95 Z28 LT1 stroked to 383 with a Automatic and 2800 Stall. He runs 11.56 at 119mph with a 1.60 60ft on stock suspension.....its N/A no Nos/Turbo/Supercharger. Were putting AFR 210 heads/Solid roller cam and new intake too run high 10's this yr...Colin (My best time in it was a 11.80 at 117mph)

 

LT1 is a really good motor.. not as badass as the LS1 however.. but, LT1's will beat you by a good bit.. and LS1's will make you look like ur not even trying..
