NA 6.0l (370) Record???

I would guess someone has one in the 520 range with a 6 speed, 10 bolt, and 16" rims. This assumes pump gas, full belt, hydraulic roller, etc.... Vengeance has had some kickass cars lately that are head/cam 364" motors. High horse head/cam 346's are in the low 500 range. I would hope the extra 24 cubes would get about 1.7 more horse per cubic inch which would be about 40 horse at the motor.

i never said a M6 car will pull harder in 4th. I simply asked if the dyno would read lower in an auto if the pull was made in a lower gear (as it did in my M6 car). So by my logic your reading comprehension sucks. Wheather his car made this number or not does not matter. Wheather his car is a 370 or not does not matter. All that matters now is that i made a post asking what the highest recorded dyno was for a 370. I did not ask for some dick lick to tell me to think things through because he thinks he is the king of cars

It is not possible for a T-400 to downshift if it has a manual valve body unless pulled into a different gear manually but they often sound like they have shifted down because of the converter's slippage and show monster torque readings till they pass the stall speed. I've never seen split readouts like the ones pictured, most Dynojets overlay torque and horsepower on the same graph. A Mustang Dyno is different than a Dynojet so usually reads from 20-40 horsepower lower numbers. There is no use trying to cross reference them as they won't read the same, ever. No way to say who is right or wrong, they're just different. The first pull my son's car made on a Dynojet with the old 481" motor it sounded like it exploded when the operator hit it at around 3500 RPM in high. It took a little over 3 seconds to go to 7200 RPM in high gear. The torque read 638 ft.lbs. and trailed off as the RPM climed. The final reading was 561 RWHP so the torque was quite a ways off because of converter multiplication down low.
+1
My auto did the same thing, spiked up, and since HP is a measure of tq skewed the numbers up quite a bit while the tc stalled up.

These numbers are corrected, I personally have put a space heater next to the temperature sensor and closed the box in which it was contained. This obviously manipulated the numbers and there was an increase of 25 whp.
Can you please show us the unsmoothed and uncorrected graph?

no i cant unless i go back to the dyno shop and since this isnt my car im not going too. It was about 56 degrees that day but i understand what your saying about tricking the dyno.
[QUOTE]and yes the mph is low due to it being a turbo 400 car and the gearing
112mph is what a bolton car pulls in the 1/4, a 550rwhp auto should run 130+mph. this dont make since , all that power with a 3speed auto, to much gearing is this a 1/8mile car? what gear is it running. looks like a streetdriver to me with the bling bling wheels .
A 5000stall/ 8.8 rearend 4.30 gears sounds like this , this car makes 430rwhp / 387rwtq with the converter locked up . Trex cam only ,4l60E 7000rpm stockshortblock 28/10.5/15's . Still pulls 120+mph in 3rd gear

LOL T I right now am battling some kind of sickness. I am not mentally preped for the nuke in which that one statement would cause. I ate crap for 3 months when I told everyone I was going to build a 370. Now I am enjoying the fruits of that labor. I dont want to end up getting involved in this 1st hand and it leaving sour grapes in my mouth. I am also not going to get provoked into telling how it was put together also. You rode in the car. You know what it feels like. The dyno may have been skewed (it was a ricer dyno after all) but I dont think 100hp. I did expect 500 at least though. The car is barely streetable. It is a race car as it sits right now. I will be pulling this cam out soon. VERY SOON!
and thrown away. I apologize for making the thread, i never knew people took dyno racing so seriously 
Maybe some time soon when he goes to Ed wright for a full tune he will post another vid and graph and more specs. He just couldnt beleive the hate that was coming to him from fellow enthusiast and didnt want to stir the pot any more.

Obviously not right. Other than near top end, the torque and power curves are essentially the same shape. This is physically and mathematically impossible. Where the torque curve is flat and non-zero, the power curve will be a straight upward slope. I'm not saying these curves are deliberate deception. Dynamometer power is calculated from measured torque. It could be that the dyno’s computer was bonkers and needed to be rebooted.
