LS1 190mph and 480 RWHP
 

Thats right, this guy I work with bolted on a set of Lingenfelter heads and put on a Z06 intake a custom ground cam
and a butt load of other mods on a LS1 Trans AM for a guy that lives in Dallas. The guy he did the car for E-mailed him yesterday and told him what he pulled on the Dyno 480RWHP and that is without the juice.

This car is a silver LS1 Trans Am, if you live in Dallas watch out for this guy....:eek:

A stock LS1 puts out 480RWHP and will do 190mph. I don't understand?:p

it's not stock bonehead

And if you even start to say "Well it has a stock block!! I might have to thump you on the nose. :p

That's not what I ment. I was saying a stock LS1 has 480rwhp and will do 190mph, so what's the big deal about a mod'd one having the same hp? :p Jacka$$ :rolleyes: I was just kidding, lighten up. I think I know the difference between a stock car and a modified one, Geez:rolleyes: :rolleyes: :rolleyes:

sorry man it just sounded like it was going to turn into one of your "Hail the LS1 posts" I was kidding too @$$hole:rolleyes: :rolleyes: :rolleyes:

:p

You get your car fixed yet?

yeppers, I keep blowing pcv out though

Heads, cam and an LS6 inake won't make 480rwhp on a stock displacement (or even a big bore) LS1. No way, no how. Maybe 408 rwhp, but not 480.

Sorry dude but you are wrong I think $3,500.00 Lingenfelter heads is were all the power comes from. He will probably make around 600 hp on the bottle.

We are not talking about ricers here these guys are serious drag racers and go to the dyno all the time.

I am sure that they did other things to the car but I dont know what..

I was much more impressed with 190mph than the 480 RWHP.

I am not a big fan of dumping 25,000 dollars into a 30,000 dollar car so you can run 11's in the quarter this guy has done everything imaginable to this car................If it was me I would have bought a viper

I'd bet money he didn't make 480rwhp on a stock LS1 shortblock with Lingenfelter heads, cam and an LS6 intake. Similar cars are making from 375rwhp up to ~430rwhp.
There are very few LS1 cars over 450rwhp NA, and most of them are big bore, or truck blocked motors.
For example, NineBall is running a very seriously developed MTI setup with a 382, stage III heads/cam, LS6 intake and all the other goodies...he's dyno'ing 455rwhp. Rapid Motorsports did a 427, solid roller LS1 iterative that made 481rwhp/547rwtq through a TH350...pretty "on the edge" for a street going LS1 car. There are also a few 42x motors that are in the ~475rwhp range.
Maybe with a 422 or one of the other large displacement motors he'd hit 480rwhp. But a set of Lingenfelter heads aren't magically worth 50-75rwhp more than a set of ARE's, MTI's or others.
I'd believe that the car made 480 at the flywheel, after adding back parasitic losses (that would put it in the 415rwhp range), but 480rwhp I seriously doubt.
All I'm saying is he didn't make that power with just those mods. If he hit 480, he did it with more cubes, or he did it with dope (although that would be a small shot on an LS1...they love spray).
BTW-How do you know it went 190mph?

Like I said I dont know what all else was done to the car it might have different pistons crank rods etc.....

The guy that done the work on the car has a old 69' chevy truck when he told me it ran 10's in the 1/4 I told him he was full of ****.

To make a long story short this guy shut me up when he ran a 10.6....

This guy knows his stuff he built a IHRA pro stock car from the ground up.

They ran the 190mph in Denver City TX..........Anyways I seen the dyno sheet 480RWHP...........If you knew this guy you would know that he doesnt make stuff up...............The IHRA car that he built runs 7's "I seen it"

The LS1 is up around 350ci there are 331's and 347's that have more power than 480RWHP Naturaly aspirated.

Displacement isnt everything

Thank you for stating your opinions in a non-hostile way, it was nice for a change..............later:D

.

Maybe he's is running more displacement. In any case, you've seen the dyno sheet and know the guy...so you'd know more than I do about the car. I think the next evolution with the LS1's is going to be a big move to larger displacement short blocks. A year or two ago, these were very cost prohibitive, now companies like ARE and MTI offer up a pretty good selection from 360-427 cubic inches.
Just when I thought the LS1 cars had "topped out" a year or two ago, they kept going. They are certainly an impressive motor. Amazingly, many of the older head/cam cars are still running fine with over 50k miles on the combos. That's a testament to the durability and performance of the LS1.
I don't know anybody, nor have I heard of a 331/347 making >480rwhp NA, but I suppose it could happen.
Later.

I think a good N/A 331/347 number is 350 RWHP. Much higher than that and you are not really talking a street car motor.

Snorman knows his $hit.

Yes Snorman does know his sh!t...........but who ever said anything about a street car...........I said these guys are serious drag racers, and yes 350 RWHP is a good # but 480RWHP is unreal for a N/A LS1 IMO and that is why I posted it.

I just wish the guy would let me drive it:D

Thats nuts, i seen a n/a 331 fox body go 10.4 @ 131, a carbed setup, but he was on open headers, and big slicks, i wonder how much rwhp he has? not really streetable, but i guess it could be made a little streetable.

190 mph:eek:, i wonder what rearend gear he's running? probaly stock, those f-bods run fine with 3.42's.

Yes I believe he still has the stock rear and tranny but I bet the tranny doesnt last long
;)

The tranny will be the last thing to go. If it's an M6 car (and I'd bet that it is if it's running 480rwhp and 190mph...I won't restate my doubts about those numbers ;)), it's got a beefy T56 in it. The T56 in the LS1 cars is pretty damn stout. The worry isn't the tranny itself, but the clutch. GM doesn't put an overly strong clutch in those cars considering an '01-'02 M6 car (with LS6 intake and other little changes) will put down ~310-320rwhp bone stock.
The rear will let go first if the car is on anything other than radials. The 7.5" 10-bolt in those cars is pretty wimpy. Problem is, to upgrade to a 12-bolt or 9" in an LS1 is well over $2k.
S.

Damn snorman you seem to really know your stuff about LS1's.......are you sure your not an in the closet chevy guy:p

Snoreman....not the case in my area, i know a guy with a 99 m6 that has his 6spd popping outta gear, and grinding, his car goes low 12's with cam, 373gears, minor boltons, cuttouts, and e.t.streets. he recently destroyed his rear too, but i know of a guy that has a 10sec s-trimmed f-bod a4, that broke his rearend months after he had been running it, now it has a 12bolt.

What im saying, i dont think the 6 spd is that sturdy, you are right aobut the clutch though, they go quick, and then the 6spd goes with it.
