I have used the formula several times in the past and been with +/- 5 hp of dyno numbers. Based on this, I deem dyno # as being a FAIR representation of the truth.

My current car has trapped over 118mph with traction and clutch issues.

Sir, you may be passionate, but you might want to consider spending a day watching LS1 cars on the dyno - your beliefs will be changed in short order. This website only provides a small snapshot of what is really happening in this hobby.

I'm sure you'll revise your signature after spending a day in the dyno.

ill go to the track and the scales as soon as get back from my one year tour in korea, and i ll hit the scales too, but when i do hit the track im planning on doing a lil bit of weight reduction, but ill post up as soon as get the numbers, heres a vid of my new setup getting tuned by jason at TSP!!!

I put down 389 RWHP & 351 RWTQ with LS6 Intake, Long Tubes, 3inch X-Pipe, Comp Cam 605 Intake 610 Exhaust 236-242 Duration 115 Lobe Sep, Yank PT4400 converter, Stock Heads that are ported 286 Intake 228 Exhaust.

My best time with these mods 1/8 mile was 7.47 @ 91 1.59 60ft

I added a ASP Pully & Electric Water Pump & ran 7.240 @ 94 mph 1.55 60ft

I figure I am right at 400 RWHP now with the Elec Water Pump & Pully

A ls6 crate engine got me to 400rwhp.

What exactly are you saying? Weve done dozens of moderate sized cam only cars and a bunch are right at 400 rwhp on our MUSTANG dyno with some of our setups.

A legit 400 rwhp should be 120 mph at 3600 lbs all day every day Dynojet numbers might be a little higher but weve still had 390 hp Djet dynoes cars go right near 120

Id be willing to put up a few grand if your saying a moderate cammed car cant make 400 and back it up with trap speed as well. And if you want to tear down the car to prove its cam only Ill have another few on that too I could use some free $ to play with for a minute

What up Jeff?

Goat Cheese, I'm not really bashing you or anyone else with a different opinion on this thread, I am just curious to see how accurate you are in your predictions. I have a car that weighs just about 3600lbs. with me inside. Unfortunately I can not post a pic of my timeslips but I am reading them in my hand right now:

You said if you had the trap speed and 60ft time you could calculate the h.p.

#1 60ft.- 1.646
330- 4.794
1/8- 7.483
mph- 91.03
1000- 9.825
1/4- 11.825
mph- 112.23

#2 60ft.- 1.663
330- 4.779
1/8- 7.453
mph- 91.40
1000- 9.788
1/4- 11.783
mph- 112.42

#3 60ft.- 1.619
330- 4.737
1/8- 7.425
mph- 90.82
1000- 9.779
1/4- 11.792
mph- 111.31
All times i have given you are different days at different times of the day. Please respond to this post as I am interested to see your method for finding the answer!

I think it is funny that when you question someones RWHP numbers it's like calling their mother a *****. Boy, if you were closer to me I would love to see you get 400 RWHP (500+ at the crank!) with only a cam change on a bone stock LS1! You said it not me, cam only, no other mods whatsoever. I would pay a couple thou to see that. And forget tearing the motor down, we'll print the 400 RWHP from the chassis dyno of your choice, and then we'll yank the engine and have it dynoed on a water break. You have to agree that 400 RWHP is at least 500 crank right? That must be one hell of a super secret "moderate sized" cam grind to add 150 additional h.p.! And your right 400 RWHP is gonna put down every bit of 120 mph through the traps in a 3600 lb car, not 112. Anyone running 112 in the 1/4 at around 3600 lb race weight that was told by a dyno shop they have 400 RWHP was simply dooped, and need to get thier money back.

GOaT Cheese

I can tell by your short times you have a very nicely tuned suspension package, but honestly at 111-112 mph, you are making around 425 at the crank, and probably around 325-350 at the wheels.

GOaT Cheese, I see now from your above post that you must be one of the minority that thinks 'cam only' means just that - a completely stock car with only a camshaft change. We both know that approach ignores the 'system' of airflow throughout an engine, and that without supprting mods, a simple cam change will not get those kind of gains. I also think most people posting in this thread have a fair idea of what kind of performance a well set up 400 rwhp car should deliver, at least in terms of MPH in the 1/4.

Also, to novass72's credit - I never saw him claim 400 rwhp. Your estimates do seem pretty accurate for him. His 60ft's give an obvious clue to the traction he has achieved, but the only performance mod given in his sig is the MTI lid and K&N.

GOaT Cheese

GrannySShifting said I could tear down his engine so I could see for myself that was truly a "cam only" engine. He offered it up, not me.

Since you are the expert Mr. Cheese, you can analyze my slip also. I have a few but I'll only post the one and let's see how close you get.

60' - 1.6692
1/8 - 7.5763
1/8 MPH - 91.62
1/4 - 11.85
1/4 MPH - 117.87

Best trap speed has been 121mph and I have a few slips in the 11.80's range but they all look nearly identical to the one above. I know what my car did on the dyno, do you?

5LETR

For crying out loud!!! Lets agree to disagree. For all we know Mr. Cheese is a 12yo boy trolling around attempting to ruin the dyno industry. That was not a cheap shot at you, Mr. Cheese, just making a point.

GOaT Cheese

I'm with you, tired of arguing and being attacked for questioning peoples H.P. numbers. I guess I did it to myself. And you're right nobody here knows who I am or what I've done, or where I've been. And visa versa. So I'll stop making accusatory comments and let the dyno queens have their day.

And what about my trap speed of 111.7 and running a 12.17? Thats with spinning of the line and 1/2 a tank. Car made 392/373 RWHP with ported/polished 241's and a small 224 cam along with longtubes, intake, built tranny etc.

novass72

Goat Cheese, I'll give you credit! your pretty close to my engine dyno results of 435hp, 490tq. I was just making sure you could back up your claims. I agree if you had a complete timeslip you could figure someones hp numbers with a relative margin of error for that particular run.

By the way those times were in my 72 Nova (I removed the info from my sig just for this thread)!
