those of you who dropped in factory ls1's in your thirdgens what type of power did you make. i'm talking plug and play, not tunning or engine alterations. i'll have mine done later in the week to share.

 

That's a great question to get a benchmark, unfortunately I'm no help...mine went in with a TR 224 cam and hasn't been to a dyno yet.

 

no one? well how about minor modifications if you didn't do major then?

 

do you consider a .600+ lift cam major

mine should be on the dyno this weekend or next, just depends when they have an opening

 

this is as stock as you can get in a 3rdgen:


dead stock untouched 02 LS1
all accessories hooked up (no shortbelt)
stock manifolds feeding thru muffler shop Y pipe into a 99Z muffler/tips... no cats...
air intake is a 90* elbow, MAF then a 4" 45* tube with a LARGE K&N... still probly flows less then a Lid....


the plugs are still the same ones that came with the motor... this motor is totally, dead stock.

transmission is the same 02 LS1 6spd that came with the car.

rear end is a LT1 one.


data is corrected, but weather was VERY humid.. it was on/off sprinking outside.. ~90*.

 

no dyno tricks were used either..... it was just driven up to the dyno, tires wiped off (rain outside) and ran twice, back to back

 

pretty good, anyone else? sounds about right though. thanks.

 

I think you will find a stock LS1 of any year will make about 300+ to the wheels. The A4 will obviously produce less at the wheels. A full exhaust alone is worth almost 330-340 at the wheels in a stock internaled LS1.

 

whatever the power number is its gonna be heads and tails over tpi and have unlimited potential for modded power

 

Im not sure what kind of power I am making yet. Im going to venture in the 350ish range or so. The A4 and the stall are going to bring the number down. But what I am also interested is in the times that the third gen ls1's are running. Ive seen a few times posted but not a ton. Hopefully i can get my car to the track pretty soon to get some times. I dont really have any clue what my car will be running, but I hope its better than 16.8 and 17.1 (dead hooking ) the last time I went to the track (pre LS1).

 

what about the weight of ls1 third gens? mine comes in at exactly 3200....

 

good question as well. Id like to get mine weighed soon as well. What if any weight reductions besides the aluminium motor do you have to get to 3200?

 

thats what mine weighs before additional weight removal


heres the nice thing about it.... i took 140-something pounds off the nose of the car.

when i first got the V6 camaro, i thought, man, with this motor set back, it really does turn alot nicer then my V8 ones...


then i started driving the LS1 camaro... it handled like the V6 one does... the nose just turns, no questions asked... and it turns flat........ and my swaybar isnt even hooked up yet! only thing on it is a set of new MOOG springs..

 

yeah mine handles so much better now too. i dont have that much wieght removed, tubular front end, and no ac basically thats all. i have a extremly strong subfame, and the cage should be going in within a couple weeks. i have all power options, but i will be doing some wieght removal after that

 

What year and model is it? Some third gens are pretty light other are a little heavy. In general they seem to be a good amount lighter than 4th gens.

 

I'm hoping mine will dyno in the 425-450RWHP range.... heads/cam, LS6 intake, LT headers, 4" CAI, pulley, and other goodies. We'll see. It's also a 6 speed with a moser 9" so the trans will help me but the rear is going to rob some power... we'll see. I hope mine weighs in the 3300 range.... I'd be ecstatic. With that weight and this HP... it should do what I want it to at the track. Hopefully low 11's aren't too far away.

 

A Heads and cam ls1 in a thirdgen should net you a low 11's pass (assuming you got a good set of heads and a big enough cam). Just need 100 shot to break into the 10's. That would be nice. I would pee myself if I could bust out a high 11 second pass NA, but it probably wont happen.

 

i've seen so many different heads and cam packages and hardly any of them break the 400 rwhp mark. good luck with it, i'd love to do the bottom end but i like having the car reliable now. forced induction will be the route for me.

 

Check out the corvette forum in the C5 section for what different combos are making. My buddies 2000 vette with AFR 205 heads, a 224/228 cam on a 114 lsa, 1 deg advanced with .580-something lift.....443rwhp. Has air intake, TPIS headers, exhaust, and Z06 intake manifold. All this on the stock bottom end. Very calm car (they call it the grandpa cam) and runs high 11's @ 122-124 on the stock goodyear runcraps. This thing has little traction in third gear at the track. With sticky tires it should be close to breaking in the 10's. Cracking the 400 mark is all in the heads.

 

thats funny..... all of us local LS1 guys hit the magical 400rwhp mark with boltons and cam... no dyno tricks either.


most of them were/are running high 11s stock internal too... season is just starting with us having cams, but most guys are running 7.2s in the 1/8th with more left in them....

 

i HIGHLY disagree.... the best part of the LS1 motor is the heads.. (well, one of the best parts)



the heads flow more then most aftermarket SBC heads... the only internal engine thing limiting power in stock form is the tiny cam.
stick a 220 to 224ish duration cam in there, and you can hit 400RWHP with it idling like stock.

 

Don't take this the wrong way, I am only playing devils advocate, but I am supposed to believe with a small cam and headers your car will pick up about 90 hp at the rear wheels? It already has the good intake manifold. Most the numbers I have seen are on vettes, and I'm sure the drivetrain loss is a little less in a camaro, but a 400rwhp cam only bolt-on car would take a little bigger cam than that (like a LGM G5X3). On the flip side, I have also seen 475-480 rwhp LS1's in vettes with a big cam, AFR's and bolt-ons.

Kandied91z, for a reference-stock 00 vette MN6 with headers, full exhaust, airbox and a tune, 337rwhp and 350rwtq.

 

yup... but dont take my word for it. just wait and see..... (or goto LS1tech and read about everyone elses doing the same thing)

 

I did. I just read all 8 pages. Most guys close to or at 400 had BIG cams. A lot of guys with heads and smaller cams were just over 400, some of them under.

http://www.ls1tech.com/forums/showth...8&page=1&pp=20

 

For those of you doubting or questioning the 400RWHP goal... it's not very hard at all. A LS1 with the LS6 intake will dyno about 315 or so stock with a 6spd. Add headers, off road pipes, a catback or cutout, a lid or pulley and you'll be 350RWHP or more. Add a cam and your in the 380-ish range no problem... and that's a mild cam. Go bigger and you can hit 400RWHP with a 6speed without much difficulty. Add heads and with a 230-ish cam you're gonna see 425-450RWHP no problem. If any of you are in doubt just go talk to some LS1 guys. Its so easy to make power with these motors its almost not fair.

 

Not doubting the potential power out of an LS1 motor. I wish I had done one instead of sticking a lot of $$ into my DFI SBC. However, what I am doubting is doing it with a "220 to 224ish duration cam" and bolt-ons, with stock heads.

KandiedZ, what is your goal power wise, 1/4 times, etc? And are you going with a stick or auto?

 

I know a ton of LS1 guys around here... including the guy that did my heads. I could start listing guy's mods and dyno #'s... I could go on for quite awhile. One guy comes to mind though... he had the GM hotcam (218/228, .525"/.525"), longtubes, duals, lid, and a tune and put down 385 or so. It really isn't that hard to get to 400RWHP with stock heads and a M6.

 

"One guy comes to mind though... he had the GM hotcam (218/228, .525"/.525"), longtubes, duals, lid, and a tune and put down 385 or so"

385<400

 

I was just giving one example... another guy in our club had a WS6 with a LS6 intake, long tubes, cam (don't remember specs but I know it was under 230*), duals, 12 bolt with 4.10's and that was it... it went 399 or 401 RWHP. Is that good enough? Its not that hard... why do you think it's so unbelievable?

 

I'm not going to say anything till I am putting down the power and I have it on paper. Its the only way for the solid proof.

 

Hate to rain on everyone's LS1 parade but...

383 cid EFI LT1

- Ported factory LT1 intake
- T56 6-speed trans
- Lunati 1-piece steel 3.75inch stroker crankshaft
- JE forged pistons

Not bad for a LT1... plus you could change some components and add some NOS and you're easily over 500HP

 

i already have my lsx in the car, i was just curious what others were doing. the goal with the project was to remain completely stock as gm put it, dependable and reliable which it is finally. just curious what others have seen.

i've already went down that road throwing money to make an insane standard sbc and it was the worst modification group i ever did to one of my cars, never again. while the lsx setup in general was not cheap to aquire and figure out parts for the swap when all things are considered and compared to a sbc it was very cheap and well worth it. the money i save on gas alone has been well worth the effort.

 

if you and your local guys have all hit the magical number then more power to you. no one says it's impossible, just very rare. with the right combination anything is possible. now those that are doing it with very little modifications and not removing the heads is where it's at. i picked 400 for myself personally because that's where i feel i can get the most power without loosing driveability from any of the cars i've had and not break anyones wallet. obviously it's not hard to throw 15,000+ into the motor with a pair of turbos and double that with gas mileage and driveability but it isn't the issue. 400 is a nice round number you can have fun keeping up with most and not kill yourself.

 

even with full exhaust, a good running motor with cold air and pretty much factory n/a internals will have to be very very good to see such 350 rwhp numbers and not rolling down hill with the wind at it's back, but it's certainly possible. the problem with the internet is it's just that, go out and play with them a bit and you'll quickly see that although easier with a lsx platform it still isn't as easy as many say and then you really loose the reliability.

there are freak motors, this is true and anything is possible, but 50 rwhp out of a cold air, exhaust and even a pulley setup is a very high expectation out of those parts on a smaller motor even during it's best day. obviously opening the motor with the right cam such things are within reason, but the whole reason to this thread is about factory n/a power without breaking into the motor as anyone who has truly played with such things will tell you gets old. i will agree about the power potential though... quite a few advantages with these motors and the computer is so much faster then the original obdI i had in the car making it nice to work with for changes indeed.

 

i've seen two identical cars with similar mileage and identical modifications put down different numbers... i'll always believe the lower number over the higher. a dyno in essence is really just a tool to base modifications off of. track times are really where it's at.

 

the track is much more reliable, even the same dyno company can have two dynos identical reading different... it's just a number in the end.

 

is that your motor? just in case you did read it off of a site, don't believe everything you read. maybe on it's best day that motor would make that, with in reason and logic it should be close to that, probably is at the crank.

if you want an L98 style comparison here is just one.
http://gmhightechperformance.com/features/0504htp_z28/

anything is possible and numbers can be pulled out of anywhere, however when it all comes out on paper the nicer things with the newer generations start with efficiency. also you need to check your pm's it won't allow me to respond to you. in theory the generations as they get newer become more efficient, any platform can be made to work quite well. the real issue is what will give you the best bang for the buck. if money is no limit it still won't guarantee that everything will be perfect. there are alot of factors that go into building a high horsepower setup. getting one to work well together with it's parts internally is hard enough, proper tunning and efficiency is very hard. when your only getting 8-10 mpg you you learn to deal with less power for twice the mileage... it's more fun in the end when you can enjoy the car rather then work on it. remember that there is no real right answer. i myself saw similar numbers on my old L98 with nitrous that my lsx setup pulls now. it was definately alot cheaper to get what i wanted but power wasn't always there and it took a toll on the motor over time. in the end you need to weigh your options and choose what's right for you.

anyhow please stay back on topic. if you have a factory stock ls1 or at least minor bolt ons and have dynoed the car please share. there are enough discussions of what a lsx setup or any other setup can do on this forum.

 

teehehehehehehe

 

Is this actually your engine and you have dyno printouts for it, or are you a 305 owning wishful magazine racer?

 

Kandied91z-

1) So you're trying to say that 350RWHP with a LS1/6speed car isn't very likely with just a lid, headers, no cats, a cutout/catback, and a pulley?? Take a look around... that is VERY common in the LS1 world.

2) Also, as for my buddy with that LS1 hotcam and exhaust putting 380-ish down... I know dyno #'s aren't everything but his car has the MPH at the track to prove the power as well. It doesn't hook well or ET right now, but the MPH backs up his dyno #'s.


*It just amazes me that people are so non-believing of the LS1's easy power potential.


That's all, I'm outta here

 

Oh yeah, he went 11.90's with that setup as well. His ETs/MPH backed up his dyno #'s

 

Just talked with this buddy.... this was his setup, dyno #'s, and track times.... whatcha think?

double post

 

lol dont bother worrying about it man... its obvious that the people arguing about it arnt exposed to LS1 stuff day to day.. just relax and be happy about your car.. im happy with mine

 

you guys are turning this into something it isn't suppose to be. there is nothing in the beginning of the thread that leads, asks or disusses any motor with upgraded internals. i personally have no interest in what cam does what. i want to know what those with stock motors are doing, if you can't leave the thread to what it's meant to be then don't bother replying. there are plenty of other threads talking about what cam does what.

keep it factory for this discussion please.

 

i never said any of the such, read what i said a little better without trying to look for something negative.

 

ok, in total agreement with what the orignal topic was:

be happy with what i posted.. lol. exactly what are the odds that:
someone swapped in a LS1 drivetrain and left it totally stock down to the spark plugs
AND
they just dynoed it.
AND
they're on this board, and have a scanned dyno sheet when you ask.




lol


dude, for a STOCK factory LS1, its going to be identical to all of the other LS1 cars... theres nothing on a 3rdgen thats going to make it go up or down by any degree larger then the normal margin for error.. the M6 cars are going to be between 300 and 320 RWHP, and the auto cars are going to be a little lower.

 

also:



the hotcam SUCKS!

 

 

True... I did get off topic... sorry... but he is right, a stock LS1/M6 or stock LS1/A4 setup in a 3rd gen is going to dyno almost exactly what it would in a 4th gen. What's the point then, that isn't any fun


Mr. Dude- Why you say the hotcam sucks?
