BINGO! Give that man a cigar.

Not saying that's what happened here but the MD's sure make it easy. There was an L92 build last year with grossly inflated numbers that couldn't be backed up. The owner later found out the car actually made almost 80RWHP less that he was originally told.

You can do it so fast, even with someone looking over your shoulder!

My car weights 3480lbs with out me in it. I weigh 215-220lbs. about 3,700lbs with me.You people make a great point,he did build the motor and it would be interesting to see what a different dyno would say. On my last set up he would have no reason to fudge any #'s because he had nothing to do with any of the build and the car at 3,700lbs was near 10's N/A.

i was wondering the weight because my car weighs 3520 w/d A3 and runs 126.5mph

You boys have me wondering,I found a dynojet about 10mi from me and I'm calling them tomorrow. Now I did dyno in the past on an old set up at speed inc and hardcore's dyno jets and the mustang dyno was 30hp lower from the lowest dynojet #'s. so,now we'll see and I'll post both graphs side by side for you all when It's over. I hope there was no fudging on this motor. I'll try to take care of this with in one week or less. TI'LL WE MEET AGAIN.
30TH TA-two different dynojets but still verry close. I would be happy if the jet shows the same as kirks. I just don't want to think Kirk would try for higher #'s.

Dyno numbers are just that - numbers. Your car runs well and you enjoy it. That's what's really important.

On my graph it showed my car at the correct weight. This was the only run down the track I got. I have no roll cage and was only doing 60foot runs trying to get it to hook. The car spun out of the hole and I hit the rev limiter also in first gear. Maybe this was not a great run to tell,but it was all I could get because they told me no more runs. This car will go 10.8 n/a when I get it togeather.

MPH shows HP, not ET

I agree. Thats why I said it sounded like a 470 hp combo by the mph.
You can run a 10.8 on alot less hp than 500 rwhp.

mike c.... where in Michigan did you run that ET that you posted above?

Guys, Hes trapping close to 128mph IN A 3700+ CAR. Your going to need more than 470rwhp to do that in this weather. IMO the 517rwhp he made on the stang dyno will be close to what he makes on a Dynojet. I already proved with the H/C 346 I bought from him that the stang dyno he uses and a dynojet will show similar numbers. Heres a list i put together of similars 402/408 6 speed cars and their rwhp & ET & mph. All of these cars are 3600lbs+ .Of course these are all different drivers and different tracks, but I think his 517rwhp & trapping 127.xx is right where it should be at his weight.

I ran at lapeer dragway. I also made one other run,but shutdown to not break out past 11.5's....no roll cage. I ran 11.49 at 126.2 shutting down early. I called the shop and they can't dyno my car ti'll mid next week. A friend of mine was there when we dynoed the car and on the motor closed cutout it made 497hp and I told the tuner I wanted 500hp closed cutout was my goal. My bud said if he fudged the #'s he would of done something like I can tune somemore and he would of got me the extra 3hp(fudging)I wanted. 497HP threw a B&B catcack and 517hp cutout open. Im looking to return to the track this weekend to try to tune my suspension and get a better time.I also noticed k-tech's 427 camaro ran 10.85 @126mph I think it dynoed 520hp on the same dyno I did. so the 126mph must mean it is actually only making 450hp.lol THANKS FOR THE SUPPORT 30TH TA.

I ran a 10.159@ 135.86 mph with 539 rwhp on a supercharged fbody. My raceweight was 3400.
Mike c's numbers don't sound to far off for his weight and mph.

The dyno numbers were on a dynojet.

What gear are you running in the car Mike c?

I live near Lapeer Dragway. I have a 427 cubed C5 w/ an A4 and 3200 Yank converter. I had it dyno'ed 2 years ago at Wheel to Wheel (Also a Mustang dyno) and was told this dyno was not generous. My car came in at just over 450RWHP. I was bummed!! My best MPH to date is 123mph, not at Lapeer, but at Ubly, if you know the track. So my bummed feelings didn't last long. However, my cam was much smaller than you are running (.595 lift, 232 duration@.050 lift intake, 236 exhaust, same lift as intake) and you have me by nearly 5mph. And I think my car is LIGHTER than yours, to boot. I disagree with the 470hp figure. At speeds of 120+, it takes a hell of a lot more than 20hp more to get 5mph!! And IF your 470 IS spot on, then I gotta believe that with the FAST intake, you will be approaching 540, or more, on a more generous dyno. That is a hell of a cam you got. And lets be fair, you are tryin' to yank 3700lbs to near 130mph in 1320'!!! I say 2 things: #1: On your combo, the intake has gotta be a HUGE limiting factor (Governor??!!!), so I am anxious to see what it will do (NOT dyno figures!) when this "bottleneck" is removed, and #2: We don't build and race DYNO'S!!! You got a hell of a good car, and in my experience, I would be surprised if you didn't pick up at least another 10hp when the motor is COMPLETELY broken in, as I believe that it is still a little tight at only 650 miles or so. A dyno is great for tuning, but I think it is best to check the differences all your tuning and equipment changes make on the same dyno, if possible. That way, you get an "apples to apples" comparison. Good luck, and I know the feeling on spinning the rears like you are. I have 315/30/18 Michelin PS2's on my car, and my best 60' was 1.88!! In comparing my cars speeds with the stock motors speeds (1/8 mi.) I saw NO improvement, as it ran 93-94mph in both cases. But from this speed on up, the 427 just KILLS my stock speed in the last 1/8 mi. And it should. I am only pointing out that it is really hurting for traction. I have a hell of a time hooking, even at 70 mph!! When I get it back on the road, I sure would like to bum a set of slicks and see what it'll do!!!

Grinder11,Nice post...thanks. All I wanted was a car at 3,700lbs to run in the 10.7-10.8 range N/A and The car Will do that when I work on the suspen-tune. Thanks for the post.

FWIW, I dug up the Hp-weight-trap speed equation. For a 3700 lb car, the engine must make the following Hp in order to trap speed @

115mph ---> 439 Hp
120mph ---> 499 Hp
125mph ---> 564 Hp
130mph ---> 634 Hp

Hp = (veh wgt) * (trap speed/234) ** 3

vehicle wgt is in lbf.
trap speed is in mph.

Great numbers for a 402! You must be pleased with its performance.

I DID IT 10's N/A. I went to the track today to play with the suspension,but no mattae what I did a 1.49 60 was the best I could get.
Last motor I was 1.42-1.44 60's. I think a 27'' tire will be added
today I ran 1/8 mi all day but full 1/4mi on the last run.
BEST 1/8 mi
1.49 60
6.970 1/8et
105.76mph I was happy with this.
ONLY 1/4mi RUN AND I hit the rev limiter in 1st GEAR.
1.504 60
7.019 1/8et
104.83
10.865
127.70
car is 3,720lbs with me in it.
I now have a trans whin(sounds like a supercharger) and a leak so I messed up something.
I guess I'm done posting on this ti'll I'm fixed,get a fast intake and maybe loose 50lbs or so. I wanted a 10sec street car and I got it.

one thing that don't add up is your 1/8th mph. i run 1.44 6.70's@102 10.60's@126.65. 3520lbs w/d. i wonder how your running so much mph in the 1/8th?
