A firebird infront of me caught my eye tonight and I was a little skeptical because it was all done up with a body kit. I thought it might be one of those glorified V6's. Got closer and realized it was a lowered LT1 trans am. After weaving through traffic he finally got loose and hammered the throttle from a roll. I was about 4 car lengths back at the time so I did the same and closed in on him almost instantly. He saw me coming in his rearview and switched lanes to accomodate me. He was into the throttle the whole way and I drove right by him, no contest at all! I can't believe I'm on such a streak. I usually never find any fun on the road and I've smoked three pretty good cars in the last five nights! Did I mention I have one of those "slow" 93 LT1's!

 

i'm not surprised you beat a 4th gen LT1. I think 3rd gens weigh less than 4th gen but you have added weight with sfc's and that stuff. But i dont think weight was the factor here.

Just wondering, do you have headers on this monster?

 

So you're basically a stock LT1 with a few bolt-ons and you destroyed a similair powered vehicle making up 4 car lengths and even blowing by him.

 

bs? he has 4.10 gears. Some stock Lt1's had 2.73's. You dont think that will make a difference?

edit: possibility the other car had 2.73's. Plus, the third gen is lighter than the 4th gen.

 

I don't think the weigh difference plays such a large factor nor the gearing to be able to blow by a similair powered vehicle by 4 cars and a whole lot more. So you're thinking "I whopped *ss" and the other guy was sayin' "look at this m*ron doing a fly-by". That's what i think went down.

 

ok. lets break it down. Add 5HP for tb coolant bypass. Add 5HP for ram air/CAI. Add 5HP? for 160 stat. Add 5HP for pulleys. Add another 10HP for chip. Hell, thats maybe 30HP. I beleive he could do it easily with his bolt-ons, gears, and SFC's. Do you have any idea how much 2.73s suck?

 

freestylzz is just talking out his butt i don't even think he knows what going on. Yeah weighing 200 lbs.less and maybe a 25 horse s stronger and 4.10's are going to make a huge diifrence.

 

Oh no another HP stacker! JK The TB bypass and 160 stat don't add power. A CAI adds roughly 10 or so to an LT1 and there isn't much hp left out of the stock tune.

He should be able to beat an 4th gen LT1 car. The TA he described could have weighed in at 3700 or more pounds and could have had mechanical issues. Even if there wasn't anything wrong with it I don't think it would have had much chance.

That being said I won't know if that guy was racing or if he got on it too late. He shoul dhave held better with a four car length lead.

 

actually TB bypass does on an LT1, not a lot though

http://www.ws6.com/mod-8.htm

 

I have seen that link and the data he collected is very random and can't be attributed to the TB bypass. It is a good idea, don;t get me wrong, but there are many other dyno sheets that show a zero increase. What it does is reduce some heat soak at the intake inlet. So it doesn't add power it just prevents a little less power loss due to heat soak. If that guy were to dyno his car cold he would have seen an even greater jump in power.

 

I don't doubt it, a stock LT1 car runs between 13.9s and 14.5s depending on driver, trans (auto/6spd), gears (2.73, 3.23, 3.42), etc.

Didn't TexasLT1 run 12.8 or something with a stock LT1 in his thirdgen?

 

First of all, the 4 car lengths behind was a guesstimate. When things go down like this they often happen very fast and adreniline gets goin, so there could be a margin of error there. Needless to say, we were both in the same lane and he jumped out to the other lane and got on it to leave the last car in our way after a light from a roll. I saw his front end come up, heard it, I was right there only a few car lengths or less behind him. So I did the same to try and keep with him and I closed very fast, it suprised me. He saw me coming and moved to the other lane but stayed on it hard all the way to almost 90mph! I had at least two car lengths on him by then and shut it down. I just didn't drive by some guy goin for a cruise, we went to 90! I don't have headers but do have a cat back. Fot those who are hacking on my mods I'll tell you that this LT1 is a totally differrent animal now then it was without the mods. Its responded very well so far. Also keep in mind the gears, the fact that my car weighs 200-400 pounds plus less than his. Also, my SFC's weigh a wopping 26lbs! Thats some pretty uneventful weight if you asked me!

 

Dude, there are always haters, don't let them get to you. When I tell people I can take stock/near stock LS1 4th gens they call on me all the time. Screw em, they are jealous.

 

actually the TB bypass kept my intake alot cooler so i guess it keeps from loosing power

 

The TB bypass inst a bad idea considering its free..

 

Removing excess heat has to do something...

 

this 'car legenth' discussion reminds me of the old joke about why women can't measure. all their life they have been told 5 inches is reallly 9.

anyway, NICE WIN!!!!!!

 

I think the TB bypass helped on my car, it's WAYYYYY cooler. I can now touch my plenum with the car running

Just to help with the weight questions, my car is a fully loaded (FULLY) '94 Trans Am GT (big heavy spoiler) and it weighs 3500 curb.

You may have raced an older auto model with 2.73s. I don't doubt you could have beaten him (especially if it was stock with possible mechanical issues) but I don't believe you "blew past him" like that.

The reason '93s are thought to be slow is because they're SD cars and basically a pain in the *** to tune, and they mostly had 2.73 gears, with only 3.23s in the sticks. The next year 3.42s were standard in M6 cars, and 3.23s optional in A4s. The '93s had alot of issues, but internally (engine wise) your engine and mine are the same and make about 300hp stock.

 

Go to speeddensity.org and check the cars and what they're runnin. In no way are the 93's inferior. They had stockers runnin high 13's just like all of the 4th gen LT1's and cammed cars easily in the 12's. I just have an advantage because of the lighter 3rd gen, deep gears and in good tune. SD or not, there are alot of 93's that are good runners.

 

I'm not debating that the 93 ENGINE is a good engine. It's perfectly fine. So is it's induction system.

I'm just saying that it's not the "best." the 94-95 cars would actually be my pick for easiest to mod, as they're OBD1 and MAF cars.

And although 93s could hit high 13s stock, 93s were typically slightly slower as they were still buggy and had a few issues with periferal items (gears etc.), other than the engine. As i said before, your engine and mine are identical inside.

 

The 93 six speed I once had was damn quick, well...after headers and SLP loudmouth.
My 97 is pretty quick, but in a smaller car would be a hell of a nightmare for 4th gens like mine.
I have the TB bypass on the 97 and it helped a little bit, same goes for the SLP CAI and airfoil. It all helps a lot if added together.

 

I'm getting coated 1 3/4 SLP's, 3" magnaflow cat, And 3" Cat-back into Loudmouth resonator with one 3" tail. This will add some major power to my already stout setup! Then I'm doing an adj.tq arm, lca relocaters, BFG's all in time for next spring. I was thinkin of throwing in a 2500 stall as well but I've got alot down low already. Maybe I should see if I can get the car to hook first. I'm a little undecided on the issue? Any suggesstions?

 

true dual 3" exhaust and forget the cats, also you may want to think about a tranny cooler

 

ya, i have to agree on the cat. if your inspection will allow dump em/it. was amazed at the difference i got when i gutted mine. i went with hooker exhaust and am REAL happy with the set up, especially the dual chrome outlets on each side.

go with a vigalante stall. saw a test where they gained .5 sec over the other stall. no not yet, but will have one within the next year. : )

lca are real nice and helped mine hook up. torque arm will help hook it up too if you have it adjusted correctly.


also on tires i have 255 16s. also had michellins before but switched to kumos and, i still have trouble believing it, they hook up MUCH better than the michellins. they were out of stock on the michs and now i am glad they were.

let us know what you decide!!

 

yeah kumho tires rock. my brother has them on his 95 ta. They are way better than yokotomas too.

 

I want a tire that hook consistently on the street. My car is just a toy and doesn't see rain so I think I can get away with BFG's on the street. I guy in town here is trying to sell me these v-rated hercules tires, don't know if they are any good? Which model number are the kumos we are talking about and do you think my car will hook with them? Also, since my car is considered a hot rod by emmision testing standards apparently I don't need a cat and the car is to be tested to 1980 standards. I really don't know what this means or will allow me to get away with? I was thinkin of keeping the cat setup with SLP's and caming the car later and then hopefully still get away on the next E test with a cam. Just torn between that and long tubes with no cats.

 

if you are not planning on lowering it, then i would consider longtubes.

The 95 TA has KUMHO ECSTA Supra 712

Just reading some of the comments and have enjoyed them alot.I currently own a 94 Z28 and a 91 B4C Camaro that is still being restored. I run our pro gas out here in Hawaii,my 94 is not the fastest on the tracks,but it is consistent.Mostly bracket racing.I have ceramic coated headers,3" stainless mid pipe out to a stainless muffler that has no name on it.A freind hooked me up with it.Still have the cat.I also have K&N cold air,msd 6Al, throttle body bypass,trick flow elbow,aluminum driveshaft,sub frames,SLP driveshaft loop.Automatic.Stock converter and gears.Our track out here is pretty rundown.I run 245/50/16 Sumitomo soft compound steet radials.The car runs consistent 13.60s but my best time is 13.58@100.95 mph with a 60 of 1.97. I dont know,just thought I would share.I am 41 and have owned at different times about 65 cars from 61 buick special with a 215 all aluminum v8 to a 78 toyota corolla wagon which I stuffed in a buick 350.I think I finaly found the cars I have been wanting.LOL.Sorry if boring but thanks for reading.
Aloha

 

nonsense, your weren't nearly as boring as me.

seriously, good to have you on 3rd gen. this is a WONDERFUL board and you WILL enjoy it.

now, off thread i know but........

is that 215 alum. v8 the same one they used in the TR8?

just courious.

 

Honestly,I am not sure.All I know is that was,if im not mistaken the smallest american V8 made.It was a plug but in the day alot of people liked those engines to V8 there jeeps because of the weight.Yes I do find this place very enjoyable with some very knowlagable people. Much Aloha everyone,keep up the good info and help

 

 

Go with a Vig2800 for the stall. I've heard they are a perfect match for a stock or mild cam LT1. As mentioned before, people have dropped .5 in their et from the stall alone.

 

The 2800 stall is a decent stall for a stock LT1, however whenever I do a stall, it will be a 3500. And that's without a cam, just so happens that the cam I want will love a 3500

Most stock lt1s will like a stall right around a 3000. And yeah, vig is a great brand.

BTW, nice car
