450RWHP with a 224/224 112LSA and stock ported heads is BS...

You need a 232 or bigger stick to make that power on stock ported heads.

The above dyno seems to be the one he is talking about - 443 rwhp/ 421.3 lb/ft with ported heads and 224/224-112 cam -- From the description, that is without a LS6 intake and it's going through a 12-bolt. With a LS6 intake it should be over 450rwhp.

I know what the websites say and SLP says its power package for the cobra makes 575FW...:nonono: A lot of performance places fluff the numbers.
I know what it says and there is as much difference between LS1 dyno output as there is with the 03-04 Cobra's (some LS1's dyno as low as 270 and some as high as 310). Most cam only cars with a 224/224 make 380-390.

I dont see stock ported heads making 70RWHP even with a great tune(the T/R stage II heads are ported stock castings).

So thats why I called BS.

But hey thats based on my experience with LS1/6's (I owned a 98'/00'/02' LS1 camaro).

9" and auto drain some hp too....
450rwhp through those would be like 500 with a 10 bolt and 6 speed.
I dont think its got that much,but even with 400 + the nitrous would be a good 10 sec car.

The 9" and auto on his combo is irrelevent. He said people have made 450rwhp with a cam (TREX) and that is true. He then said a 224/224 cam and ported heads made 450rwhp -- that is correct or atleast close.

I don't know what his combo dynoes at, but with a decent shot 150+ that could be a 9 second car.

Sorry, but too much bench racing. I am sure it's possible, but it is harder to run 9s than how you explained it.

Aside from that, an LS1 can go from 270-290 stock to 450 to the wheels with cam, manifold, and stock ported heads?

Your average cam only with full bolt ons and six speed will be betwee 380-420. You may get a few freaks, but not to the tune of 450 cam only. Dude is smoking something.

I didnt see heads listed. 380ish with that big stall is what I would say. If he locks his converter for the dyno 400's are possible. NA that is. With juice a 150 shot could net him 200. I have seen that several times. Or it could net him 120. Still................Badass ride!

Hence the reason I said it "could" be a 9 second combo.

Well, you are really low balling the LS1. Some pulished numbers I can think of....GMHTP during their "lid" test dynoed a '00 Z28 at 33xrwhp with a lid. MM&FF dynoed a stock SS at over 320rwhp. Evan Smith ran 12.8x in a stock '99 Z28. They definately make some power. It's not uncommon for any '01/'02 fbody to put down 315rwhp.

Go check out LS1tech....I've seen several people with over 430rwhp with a TR224 and ported heads.

has anyone seen or heard of a ls1 with a cam only making 450 hp

his post=
you're a stupid ****. people make 400whp with cam only motors. hell, people do 450 wheel hp with cam only (trex). just stfu now.The above dyno graph is from a 1998 Camaro SS (6 speed) with Thunder Racing's 99-224/224-112 Camshaft, GTP/Thunder Racing Stage 2 Cylinder Heads. The car has a full compliment of bolt-on modifications, including Whisper Air Induction, Thunder Racing ported throttle body, Grotyohann long-tube headers w/ 3" y-pipe, Borla cat-back exhaust (no plate, ) ASP Pulley and Royal Purple Synthetic Lubricants. The car also has a Moser 12 bolt rear end with 4.10 gears. the graph shows 451hp and 406 tq

Cam only means cam only.
Maybe a bolt on or two.

No, I wasn't bashing the LS1 at all. I know they make great power. I was just curious because I thought most LS1s made like 270+ in stock form. No wonder they're nastier than they are rated! And trust me, I have seen my fair share of stock LS1s running 13.0s to believe that a better driver could go 12.90s easily.

All LS1's make about 345bhp SAE Net +-

GM "offcially" rated the Fbody lower (various reasons), but it was only marketing.

LS1 Fbody's tend to dyno similar to C5 Corvettes and will run pretty similar times. The Vette has a slight weight advantage and top speed wise has better aerodynamics.

Fbody's are limited too 158 or 162mph (model dependant) although it has been seen that a stock m6 Fbody with the limiter removed will top 172mph. A Corvette C5 should see another 10mph plus, which is red line in 5th.

But yay on a dynojet a m6 Fbody will generally see 300rwhp+ with a maximum of 330rwhp when using STD correction.

Generally 01+ cars see 5-10rwhp more, but not always.

Auto's will dyno much lower ~280rwhp range, espcially on a load bearing Dyno like a Mustang Dyno. Maybe even as low as 260rwhp, but on such a dyno the estimated engine hp is still ~345bhp SAE Net.

Ls1's are my no means the greatest engine ever, but they are pretty awesome. Compact and lightweight (440lb dressed) and they do respond very well to mods.

Recently a m6 Fbody with TSP MS4 cam (fairly wild but totally streetable) and TSP Terminator heads (not the cheapest but budget at only $1600) with a FAST 90/90 intake and usual exhaust mods made 485rwhp.
