Yeah because I really have a whole lot to gain by lying about what it made right? Please explain how? Just thought that some of you would like to see the videos....nothing more or less. You should know by now after reading this thread I could really care less what the numbers were. I let the track speak for the power.

Your more than welcome to come to the track and see it crank off 135+ MPH trap speeds anytime you like. We will even pull it up on a scale for anyone questioning the weight. Only stipulation is...your proven wrong - you buy steak dinners.

This is a video LAST year, with stock port IRON (86lbs heavier) than the now CNC Heads that are on the car now. It ripped of over 132MPH here at nearly 100lbs heavier.

http://www.azzatochips.com/videos/chevelletestvid.mpg

You can be sure the car will hit over 140MPH this year with the weather turns cooler. I will be sure to post the videos when it happens.

Not sure how long you guys have been into racing but to get over 138MPH takes LOTS of power.

Smoke'em up agrees However I think its about 20-30hp overstating in its figures. But every car I have ever dynoed and had good weight on vs track results its within about 30hp. Usually on the high side. So I would say to go 139mph in a 3650lbs car would take 790-800hp.

You Entered:
Vehicle Weight - 3650 (lbs)
Trap Speed - 139 (mph)
Drivetrain Loss - 20 (%)


Results:
Rear Wheel HP - 665.6
Crankshaft HP - 832
Power to Weight (rwhp) - 5.5 (lower is better)
Power to Weight (crank hp) - 4.4 (lower is better)

It also takes a LOT of power to go 138mph in a nearly 4000lb car!
People also don't realize, trapping a lowely 115mph takes quite a bit of power. If you can go 1mph faster every 10', that's quick in my book!

Sorry Jesse you said you Dyno'ed it and got those numbers I want to see what a 700hp dyno sheet looks like.Between Dyno #'s and trap speeds the truth is out there.Sure we have the option to data log but older cars don't have that and the dyno is one of the best factual measurements that can be made on them.I just want to see the paper to back it up. If video was what you wanted to show it is not what is in your title.I doubt a lot of things till I see the proof.Where did you come up with those numbers if not at the dyno?So the Chevelle weighs 300lbs more than my Vette?That is what you plugged in to get the numbers you posted above.

Ski, My 70 Chevelle, 3600 ponds went 125 mph with 503. I expect to see 200 extra plus HP to give mroe than 10 mph. I know there are so many variables, But just watching the video the car seemed slow to accellerate on the dyno. No biggie, still a fast car.

Look I don't fib and when it comes to cars I am about as straight of a person as you will find. They numbers are what were on the screen after air correction using SAE correction factors for the air we were in ~3200 DA, verified by charlies Altronics DA meter.

The car is still there at their shop getting the work done to the suspension that we originally took the car down there for. The dyno as a I mentioned was just for fun, and mainly to see where the max power was for converter fine tuning, which it looks good at 5800 stall.

We will undoubtably NOW ask for the dyno sheet and I will post it for you to see. But believe me when I say, I could honestly care less how much the sheet says. If it said 1000 hp I would be saying BS too. If it said, 400 I would be saying BS. However it did fall into a reasonable range for the trap speeds we run, and the weight.

You asked about the weight of the car. Yeah its today at 3650 give or take 20 lbs. It was weighted last year on several occassions at Etown, at local scale hangout. This was with the iron heads on it, and they weighted 86 pound, and were replaced with aluminum cnc heads. Different intake on it, and WB monitoring system added. So based on what those components weighted that were added and removed, off last years weight the cars as it sits today is around 3650.

I should also add that in the video above, there is a 80# sandbag in the truck that offered some assistance in traction...so in those videos at that time it was pushing 3800lbs.

As I said, we go all over to different tracks from NY, OH, NJ, MD, PA - it wouldn't be the first time someone comes out to a track to check up on our validity of information cause they call BS. I do not take it personally, infact I think its funny when they waste their time, and see the look on their faces then they come up acting like they are going to uncover the big story and find out they were 100% wrong in calling us out. As I said, only retrobution I ask for is a steak dinner.

Can I ask how much power you think it takes to push a car to 138MPH at 3650lbs?

Don't take my word for it guys. Call the booze brothers racing yourself. www.boozebrothersracing.com

And I hope you guy realize that I am stating flywheel HP, and not rwhp.

Steve just doing some quick calcs...503 x (503x.20) = 603hp. and you went 125MPH. I am saying we are on the dyno that day, that dyno 770hp, that is about 13-15MPH quicker that you. Which is 138MPH. Not knowing what DA you ran it in, what dyno you were on, etc...I would say the numbers are real close.

But like I said, call them if you don't believe me. I don't think I would tell you to do that if I were making it all up. And if you don't believe the numbers they tell you then....well I guess we can chalk it up to another over-inflated dyno result. Would not be the first and would not be the last. Really could care less - All we care about is what it does on the track and I don't see too many ALL iron body, full interior, full weight cars going over 130mpH, so I would say its safe to say we are ahead of the game. And I don't think guys with several world championships would again reiterate to dad today they feel the car could break some records, and has EASY potential to go 9.4s with the right hook up. Again take the time to call them if you don't believe me.

Just don't call me a liar.

Not to get into the middle of a arguement or anything.. but your acutal flywheel hp is likely to be that high (or higher) with those trap speeds..

However, the dyno will probally show something quite lower than your expecting.. The reason... the car probally has a really tall gear and a really loose convertor.. that just doesn't show HP on the dyno.

I remeber one guy being really dissappointed that his car only put down 300rwhp.. What I couldn't explain to him was the 4.10's and 3500 stall was killing the RWHP numbers.. needless to say he was quite happy when he took it to the track and ran a few 11.80's @ 114 on the stock short block

Exactly why I would like to see the sheets. Calculations based on trap speed are one thing Dyno is another.If it hits 139 more power to ya.I am just curious.

Not calling anyone a liar, and my car was 503 Flywheel HP.

steve40th.

Not sure. That is why dyno numbers are so confusing and I hate to even see them or use them. The intent of me sharing was just to put the video out for others to see. THought it was cool and I get lots of emails with other guys and chevelles that have questions both here and on other forums.

What times does yours run, cause for 3600lb car to run 125MPH with only 503hp is a REAL stretch. Not saying it doesn't run 125MPH I am sure it does, but I think you have more power than you realize on tap:

You Entered:
Vehicle Weight - 3600 (lbs)
Trap Speed - 125 (mph)
Drivetrain Loss - 20 (%)


Results:
Rear Wheel HP - 477.4
Crankshaft HP - 596.8
Power to Weight (rwhp) - 7.5 (lower is better)
Power to Weight (crank hp) - 6 (lower is better)

is the car a manual? Cause that alone will yield you a good 3-5MPH better than an auto....

This conversation is exactly what I am talking about when people start comparing dyno result and expecting the same thing in real world. You have 503fwhp which would only be about 400rwhp - that is going to be VERY hard to hit 125MPH in 3600lbs with only 400rwhp. You would need near 500rwhp to do that.

I think you have a little more on tap than you realize and that is what is causing the confusion.
