THat 350 needed 2 power adders to hit 444whp?

Buzzlitonian · 11-03-2010, 12:51 AM

4th Gear: 352.4 Rear Wheel HP, Torque 293.2
5th Gear: 375.7 Rear Wheel HP, Torque 300.8

I was told to get Engine HP divide by .8

4th: 440 HP
5th: 470 HP

Did three runs and the best of the 4th gear run we kept
Each time we got to 160 mph, 7500 rpm got the electric cutoff, it was starting to flatline anyway. The Fuel and Air looks good all the way through.
It was 61 degrees outside. Oil temp never got above 250F
I asked how the Dyno itself was calibrated and the Tech told me it was all done through the software. I asked how often the big wheel is greased up and he said every 6 months or by hours whichever comes first.
Running Super Unleaded, Stock pipes, no oil cooler, just skin and bones.
Hopes this helps anyone else.

That might work randomly for random engines, but it's not going to be consistent nor does it work mathematically.

HP = [Torque * RPM (at given torque value)]/5250

Test

Buzzlitonian · 11-03-2010, 02:16 AM

Yes. It looks to me you are right. This one is for Rotational Horsepower.

Lowers my Engine HP numbers by about 40 on each (if peak is 6700 - 6900 rpm).
Some could consider Horsepower is actually obtained in a quarter mile run matched with the weight of a car and how fast it is going when it hits the trap in real world conditions.

HP = weight x (velocity/234)cubed. The Dyno is Static.

Thanks for the post on that. I don't know where the Tech guy got the .8
I bought it though.

The Tech guy probably didn't have to take a lot of physics for his engineering degree

Edit: I use that equation you posted for my hp/weight based trap speed calculators...incredibly accurate, neat math trick used in it to factor in drag. I was able to confirm this when it actually calculated the top speed of the Bugatti Veyron SS within about 1mph based on the stock ones stats (since drag & frontal area would be very close).

Well done car. I like the PW Amuse, Gunmetal BBS combo.

He wAs probably assuming 20% drivetrain losses.

Q8y_drifter · 11-03-2010, 05:29 AM

That formula the tech gave you was to obtain a rough estimate for your BHP since you already have WHP.

RCZ · 11-03-2010, 09:42 AM

^ Exactly, thats a little high for a RWD system though. More like 15% normally (on dynojets). By his math I make like 570bhp hahaha, so far from the truth.

Q8y_drifter · 11-03-2010, 09:46 AM

^ you're making 456whp?

RCZ · 11-03-2010, 09:46 AM

455
