notice the other thing you can see on both of our dyno sheets... the hp is just a flat line going up.... no curve..

the power is just so linear and smooth that you really cant feel how hard it is pulling..

 

that is just plain unreal. maybe when i re-power the ol' girl she may just get a ls1 enema.

then i'll have the best of both worlds. ah what the he11, how bout an ls7? what's 10k after all the money i have already spent on her?

 

10k? ohh, thats about half the amount you'd need to put a LS7 in a 3rdgen...

10k? ohh, thats a good downpayment for one...

whats 10k? ehh, not enough.





ok, im done.... LOL... the genIII and gen IV motors are really coming down in price, but the LS7 will remain like the LT5.... VERY high priced.

 

My friend has an 02 Z28 with a good amount of bolt ons, and has been mid 12s @ 114mph, which is flying! I can easily see 11s with traction and all the bolt ons!

 

since we are being picky.....last time i checked the ls7 was NOT available. (according to scroggin about 2 weeks ago)

with only 25k on this engine maybe by the time i put the other 3 kids through private school and college (one at nc state now) the ls7will be available and cheaper.

 

Yes it is, you just have to know where to get them

Saw one still in the bubble wrap for $14,500.

 

My best trap speed was 109.6x with the mods in my sig. That was with a ****ty 1.99 60' time. I'd LOVE to get a good set of tires and launch this damn car but I don't want to run the risk of breaking the rear. Granted the car is an auto w/stock converter I still don't want to chance it.

 

slight update..........

couldn't find the ws6 TA but ran into the ls1 ss again on a flat surface.
stop light turns green and we roll into it. i hit it hard first and he stays about mid door until my ol' girl bites then i start to pull past. by the time i get second i am still pulling him and he shuts down.

question........the ss has at least a cat back system.....how much fast is the "full bolt on" ws6 TA?

by the way the guy in the ss was a class act.....pulled up next and gave a "thumbs up". just kinda gives ya a warm fuzzy feeling.

 

That full bolt on WS6 is going to be a TON faster than just a catback car.

Also, not to keep bringing it up but you got to the top of 2nd, that's not a full blown race. Just don't get too cocky over there.

 

"a ton faster"..........can you be more specific? .5 sec in 1/4... 10 sec in 1/4? ( i don't know if the ss had more that cat back that was just why could be seen)

again, torque should win off the line with ls1 playing catch up. no intention of being cocky, just VERY pleased with the result this engine is providing.

who'd a thunk a lowly vert 3rd gen could hold off the assults from lt1s, ls1s, lighting strikes, and a super charged cobra snake bite?!!

stop light wars are just 2dam muchfun.

maybe the stealth ram and a better rear end ratio will help the trade off with torque and top end performance but for now.....

tanks fer da input.

 

you know that ls1 would probably start reeling you in if you were going over 2nd gear...and full bolt ons should EASILY hit 12s with a good driver. its crazy to see what times people can pull with bolt on LS1s. good job though

ill let u guys know what my new cars running like once i install everything, ill get some dyno #s etc..

 

i really DONT doubt your nice 350 couldnt make some major power down low. mines the same way.
after reading alot on ls1tech, alot of the ss's stock, with M6 are making like 315+ rwhp and alot of them are 12 sec. u have a nice motor on your hands

 

agreed on the reeling in stuff. tpi is a torque motor. ls1 has an ironing board dyno sheet. the question is not if, but when he catches me. hopfully it's a short road and/or he give us after looking at my bumper.

also understand, i have tremendous respect for the ls1. heck i respect almost any car except for yugos. (although i must admit some of these cars with the gaint cans on the back look funny)

i hate to say this after all the money i put in this car but after reading these ls1 comments and seeing the dyno sheets i have actually looked at a couple in the ad section........no, no save me!!!!!!!!!!

oh ya, thanks for the complement on the engine and can't wait to see how ur cars does.

will up date as information becomes available.

 

its OKAY to fall to the DARK SIDE!!!!

"Luke....i am your father......"

 

ok darth, stop polishing ur helmet!! you'll go blind. lmao.

 

Get one!! You won't regret it, guaranteed

 

A "full bolt on" LS1 could very well be in the 11's. Depends on a lot of things though.

With the mods in my sig my best ET is 12.84 and my best MPH is 109.6. I don't have much done. If I actually had some decent tires that 109 could net me 12.50's all day long.

Oh and Stealthram=gooooood

 

LT1s having more torque down low and beating them to the 1/8 is a myth

total BS

 

I know. I'm waiting patiently to throw some 315's on the back, after I install a much stronger rear-end, of course.

 

Just to mention, the above is not my car... but it is in fact a WS6 that is sporting some 315's.

 

Having spent alot of time in my best friends stock 98 Z28 (A4 w/ 3.23s) I'd have to agree. We absolutely raped multiple LT1s from a stop and from a roll. Now having a LT1 (A4 w/ 3.23s) myself I don't buy this LT1 beats em down low crap.

Anything can happen on the street with unequal drivers, but everything being equal I don't buy the LT1 winning to even 60mph, much less the 1/8th mile.

It doesn't pan out, if you look at the average 0-60 times posted for both the LS1 is better, and the average bone dead stock 1/8th mile time for a LT1 is around a 8.9-9.0 or higher. LS1s typically run several tenths faster than that...


Heck, I'm just hoping with my shorty headers, catback, and CAI I can match a stock LS1 pretty well... I got a feeling I'm dreaming even there...

 

i would think you have a VERY good chance. with the vortec heads etc and then running a carb that engine should be about 400hp.

in talking with brian when i bought my engine he said with a carb is was good for 30+more hp. it came from scroggin at 357 so with 30 more for the carb and a few extras make the 400.

good luck keep us informed!!

 

Get a good stall, and you're right there with LS1 cars.

 

He will need more than that. My stock M6 LT1 car was no match at any speed for the above mentioned '02 SS. He would kill me from a dig, roll or whatever speed we went from.

 

not wanting to start any arguement but...........
why am i having any luck then?

 

Your car is lighter and most likely better geared. Your motor makes its peak power sooner (basically off idle) which all translates into a perfect street car to beat another with more power.

 

O.I.C.

i was referring to your comment about getting pulled at any speed by the ss ls1.

as for gears......still stock....2.77s i think. and yes i plan to go to 3.23s or 3.42. with the traction problems i am having i just want to wait for the HSR first. then maybe i can keep the extra pull with the gears from going up in smoke.

and i just loved being called "perfect".

 

Eh, he'll need gears too...and long tubes (I just realized he said shorties). An LT1 (especially the later ones) with LTs and full exhaust, gears, and good stall converter (3000-3200 or slightly higher) should be LS1 territory all day.

 

OK update time.

turns out the guy dating my step daughter knows this guy with the TA.

he has a little more than he let on. exactly what we don't know but somewhere between 7 to 10,000 dollars worth of "what we don't know".

he asked him about how he ran and he pulls out a bunch of tickets from the strip. are you ready for this???????

guy is running consistent 11.3s!!!!!!!!!!!!!!!!!!!!!!!!!

i STILL can't ge my mind around that. and no, that is motor only. but he did have slicks. that is fast in my book. shesh!!

heck even with the stealth ram and the gear change i'm going to be looking at his bumper before the 1/4 is up. we are trying to set up a run and will get vidieo if he is willing. should be fun

will post again when it happens.

 

he has alot more then bolt ons...he could have heads/cam..11.3s are pretty quick...
oh update here..
my 2000 z28 got in a wreck and could very well be totaled!! if the insurance company does classify it as TOTALED dont be suprised if i get a 01-02 SS or WS6!

 

oh man, sorry to hear about your car. hope it turns out well fer ya.

you are correct about his car. we found out in one package where he spent 4k (lol about what i spent to purchase my entire engine). kinda figure that was heads and cam. will try to find out about the rest.

MERRY CHRISTMAS!!!

 

$7-10k and he's only running 11.3s? I'm looking to be running mid 11s with gears, suspension, tires, LTs, lid, cam, and a tune. For the kind of money he has into that, he should be well into the 10s.

 

yea, if you know what you're doing, you can get a LS1 Fbody in the low 11 range with just basic boltons.
most of my friends are/were around there totally stock internal.

 

part of the cash also went to have the tranny redone and the rearend re-done including replacing the axles. don't know where that puts the $$$ at but sure has made for a fast car.

he also bought a spray system but has not put it on yet.

is there a short answer for why the ls1 makes so much more power over the tpi. yes the long runners hurt the tpi but that doesn't seem to explain all of it.

 

yes.

it is a better motor design.

the heads flow alot more air.
the valvetrain has much more agressive ramp rates
the intake flows more air (and has long runners)


theres alot of reasons, but basicly, its just better at everything.




on the flip side, comparing a TPI motor to a "standard high performance carbed SBC"
the heads suck.
the intake really sucks
the cam is tiny.



the insults get worse when you compare the L98 to the LS1 directly....

 

oh, come on now tell me what you REALLY think. lmao....thanks

although, now i am starting to develope a case of ls1 envy.

maybe a shot of nitrous would help.

 

dude i dont think i have ever heard of a bolt on LS1 doings 11s....maybe LOW 12s.....but honestly i dont think ive read/heard of an 11 second bolt on LS1...i wana see how they hit their LOW 11s with bolt ons...but duron your right with the 02 cars you had the LS6 intake already so that takes care of your intake, and another 7-10k should be a nice chunk of money to take you into the 10s..

 

Open your ears then

 

well, if the guy had not produced the slips from the track skeptic would have been my 1st name.

with the slips, well what are you gonna say? 'cept...dang that thing is fast.

also leave zero doubt as to why he took the cobra home and came back with the TA.

 

show me proof or thats just bs im always on ls1tech and i never see anyone saying their running 11s with BOLT ons

 

will try to get one of the slips and post it.

 

Those slips don't matter. No one is doubting his 11.3s. With 7-10k into the car, that guy is obviously past bolt-ons and has at least heads/cam.

As for bolt on LS1s in the 11s...I'm not sure. I guess I really don't doubt it though on some cars, like the ones that ran high 12s out of the box. Gears, slicks, torque converter (if auto), lid, ported MAF/TB, full exhaust, dyno tune..it'd be close.

I know cam cars go easy 11s. With decent heads, you're looking at 10s all day.

 

geeze, look around before you discredit something.

theres a entire stock internal list on LS1tech...

http://www.ls1tech.com/forums/etdb.php

go there, select the stock internal list from the drop down.

YES, the top cars that are in the 10sec range are basicly gutted drag cars.

the following 4 pages of 11sec cars arnt.
and i can backup atleast 7 of thoes with runs ive seen with my own eyes.. lol.



the main key is something alot of people on here seem to ignore.. they have dreams of big engines, but they forget to put the power to the ground as soon as possible... most of thoes cars on the list have atleast 1.6 second sixtys.... thats considered to be the minimum normal short time... otherwise, you have problems hooking.
you have guys on here with "400hp" motors that get 2second plus sixtys... its no wonder they have trouble breaking into the 12s...

plus bolton LS1s usually dyno around 350ish at the rear wheels.. thats more power then most modified 350s on here...

 

Very good point. Here in the mid atlantic, we have scores of 11 second bolt on LS1's. Bolt on meaning no mods that touch oil. Its an internally stock LS1 from the factory.

These LSx engines are amazing. I knew they were nice and made power with mods but I was never interested in them because I was into LT1's and LC2's. Having one in the GTO gives a great appreciation for what they can really do.

 

DING!

 

yah not too common...you seem so happy to prove me wrong!! congrats!!!their great drivers then, and i bet they have some good weight reduction too!

 

No, not happy. Just trying to educate you. You acted like a bolt on 11 second car was totally out of the question and that it wasn't possible.

It's very possible.

 

How is she running so far, fly? Finally found the time to do the FRA mod, and threw on an SLP lid as well. Hmm, the LS1 does seem to make a little bit of noise after all (so freaking quiet, stock).

 

An A4 LS1 with LTs, ORY, cutout, lid, LS6 or LSX intake, 3500+ stall, tune(duh), and slicks with some weight reduction and suspension will hit 11s

 

Best time so far is 12.84@109.6.

Mods are in my sig.(ported TB and suspension stuff isn't listed) I haven't run since I lowered the car but I did the rest of the suspension(aside from a torque arm).

I might pick up a fast toys ram air before the track opens back up.

I have what I wanted though, a reliable, consistent 12 second daily driver that gets decent mpg.

I'd LOVE to get a set of sticky tires and get that ET down to go with that trap speed but I can't afford a 12 bolt yet.
