500hp?

[fastz99]

how can i make 500 hp with no turbo or supercharger? what would i have to do

[1fastcamarosss11]

heads, cam, intake, exhaust, lid, maybe n2o, start there. but remember it doesn't matter how much you have, if you can't put it to the ground. :yup:

[nhraformula]

best way to do it would be use a 402 engine and go from there.
as for the 346ci ls1, its not gonna be all to easy.
the car wont all too streetable.
to get to around 500 rwhp, youll need a big cam like a lg g5x3 cam, afr heads, fast intake, nick williams throttle body, long tube headers computer tuning and so on.
even with above, i dont see above making more than 450 to the rear

I got 500RWHP from my LS1....H/C...Headers/Intakes/Ported-Polished TB and a 100 shot of nitrous....didnt last long though....LS1 can't take it....unless of course you build/forge the bottom end...then of course you have spent more/as much money as you would spend if you just dropped a 402 forged stroker motor in....and a LS1 aint gonna run with a stroker....if your goal is 500RWHP get a 383 or 402/408 Stroker and have at it :)

[fastz99]

i dont want to use nitrous i forgot to say that in my post. i want to be all motor. u guys are saying that even if i did it would not be able to handle it?

[Smokinstorm]

Making the 500 with a stroker motor isn't hard. Making the stock rear last is. Getting an A4 to live behind 500 horsepower isn't all that easy either. I don't know what transmission you have. If it's a manual, hooking up 500 horsepower is going to be a challenge. 500 horsepower is a number that seems to be thrown around all the time these days. Just remember that's a whole lotta power.

500 from a stock cubic inch ls1 without a power adder is not going to happen.

[juiced00ss]

nope dont think so either. My buddies ta has afr heads, cam, intake, longtubes,all motor he is laying down around 430 to 450. My car with just a cam, 125 wet shot, and a loudmouth with stock cats and manifolds is laying down 466 rwhp and 525 rwtq with no problems. As soon as i do my longtubes and y pipe i will have my 500hp with stock heads. And i have almost 90k on my car. So doing a H/C package with a shot of juice or a F/I setup shouldnt be a problem, as long as you have the money.

[ninobrn99]

i just read a thread that someone put down over 500 with carteks stage 4 heads and cam, 90/90 setup and on the stock bottom end with the exception of better rod bolts. not saying its true or possible, just saying I just read it. dont remember if it had a graph :think:

My 408ci put down 596 on the engine dyno and 505ish at the rear wheels...Then you can always add a power adder :slash:

[1fastcamarosss11]

ok i have to ask? i keep getting the emails on this thread. are we talk 500 hp on motor, or 500 at wheels, that's a big difference someone fill me please. :dunno: :thinkin:

[fastz99]

500 hp to the wheels

[SSilver2K]

500rwhp can be done on a stock bottom end. Good set of heads increasing compression and supporting mods. Might as well build a new motor though.

[Devylyst]

So it doesnt matter if its an ls1 or ls6, as long as the cubes are starting at 383 and up, plus supporting mods, you should be close to or at 500hp?

[AU98TA]

All you need to do is purchase this guys car (http://www.ls1.com/forums/showthread.php?p=244150#post244150). He got it up to 435+RWHP without heads, cam, nitrous, or FI of any kind on the stock block 346ci LS1. I'd buy his and get a good set of heads and a wild cam and you should be there no problem.

[98_Formula]

i think you should concentrate more on how "fast" you want your car then how much power you want it to make. There's alot of guys with ~420-440 rwhp cam only that run 10's with proper setup.

that was going to be my next point. If your goal is just 500 hp, then dont expect to be able to show it off on the street. The car will more than likely be a dog till about 4k or so. This is gonna be a top end only car. Is there a certain ET or trap you want?

[fastz99]

i want to run mid to low 10s. what kind of cam did they have and what did they do to get it to run that?

[98_Formula]

the cams that htose people run are generally the TREX, also the LG G5x4 cam, and theres now a new one called the "trex killer" which is running like a 10.2x or maybe even a 10.1x. They also have supporting mods like the Fast 90/90, high stall, generally 4000 - 5500, slicks and skinnies, etc. Also most have some weight reduction, some have alot of weight reduction.

of course full exhaust and bolt ons! and there gearing is usually 4.10+.
heres the fastest "cam only" list form ls1 tech, you can see there full setup, raceweight, cam, gears, etc. it will give you an idea of where u'll want to be for the cam only 10 sec ride.

with those type of cams you need to fully upgrade your valve train and also gonna want to upgrade your rod bolts, becuz you'll want to spin your ls1 upwards of 7500 rpm!

yup! I saw that post the other day as well. Pretty damn impressive if you ask me. :notworthy:

[50anv03]

stage 2 cam and heads, lifters, rockers, rods, springs, kooks long tube headers with hight flow cats and a corsa exhaust. I should get the car back in about a week. they claim somewhere between 420-440 rwhp. i will let you know the results when i get it back.

[perkdaddy08]

An ls1 will hold alot of power as long as you have it tuned and set up right. My car puts down about 560RWHP on a 150 shot and it has no problem with this setup. As a matter of fact I daily drive the car. And the thing is I have the stock 10-bolt with 4:10's and it is a 6-speed car.

[Killer_bluebird]

Like I said before, A naturally aspirated 500rwhp with stock cubes LS1 that is daily drivable is a tall order, Most of the cars running big cams like the T-Rex and G5x4 are not that street friendly. Also by the time you finish upgrading your engine to be able to make and support that kind of power, you could have bought a 402 LS2 and be making the same power in a more street friendly package and have room to add even more power in the future.

but your also not spraying it 100% of the time. without the nitrous your motor is even a bit safer since your not running as much timing N/A.

500 rwhp is attainable on a stock LS1 block but it won't last long, I know that for a fact cause I did it in my TA which is an M6. My car is streetable but barely because of the cam I was running. Basically I nailed down 500 rwhp and 500 ft lb with full bolts on's, open exhaust, computer tuning, stage 2 heads with a TR 230 cam on a 600 hp ram clutch and a built rearend which I baby all the time now. Bottom end last for about 4000 miles then bottom end went bye bye so I opted for a low compression forged bottom end with the stock cubes for a procharger. With the setup I have now, I still push about 490 rwhp. Problems I had running my setup were durability, hard cold starts in the morning, waiting for the car to warm up just to get it going, loss of vacuum for the brakes, hence, I added a vacuum brake booster which helps out a lot with my once erratic idle and horrible braking. Trust me, it's not that fun coming off the offramp of a freeway, hitting the brakes and the car dies out. Praying I don't spin the tires next to a cop, believe me, I get nervous, praying I don't get pulled over for my car being too loud. Traction is an issue with that much power in an M6, I've started in 2nd just for shits and giggles at the track and hooked up like I started in 1st :lol: But as the power goes up, so do the list of mods. New built T56, built rearend, moving on to a 12 bolt soon, and stiffening the chassis and a lot of suspension work to get the car to hook. Tires I roast through every 3 months because I run with only drag radials in the back and they spin a lot even at 1/4 throttle hence the reason why I drive a beater car around town and am looking into a streetable V8 that I will hopefully leave bone stock.

[cam02ss]

i've heard of it being done but getting there as said before, is the difficult part. i have GTP stage 2+ heads, a t rex on order along with the FAST 90/NW90 TB, and have other supporting mods such as longtubes,etc. and im not expecting anything more than 440ish. as far as streetability...im kinda worried. i have no idea how much bottom end im gonna lose but im sure i won't have much below 3500..thunder told me that past 3500 it's like a rocket ship...we'll see. i'm also worried about cruisin on the highway in 6th..dunno how the surging is going to be ,etc. but ehh what the hell right? mind as well try it.

if you have the money and want to make the big hp...get the bigger cubes.

[fastz99]

All you guys with 400hp and more. What kind of tourq you guys putting out and what kind of ET are you guys running.
