Did my first high boost test today with my BPU (no +) Supra,

calibrated the speed and set the weight....


Set the boost to about 1,30 bar (19PSI)
Up on the freeway....60mph then flooring......pulls up to about 120mph....

Then reading....... 4 2 5 HP !!!

if this is RWHP i guess I did something wrong, or is it possible to have these figures with an auto tranny at just BPU, I think the wind was helping me a bit maybe it was pretty windy today and it was at my direction...does this affect the reading much ?

I have to test it at somemore roads to be sure, maybe the road wasn't compleatly straight, maybe it was a little downhill....

Please comment this...what figures do you other read out of your Blitz Powermeter ??

I was hoping for about 380RWHP .......

Well on the highway you have cold, 100+ mph air rushing into the intercooler. Plus the engine has to push the weight of the car and overcome aerodynamic drag so it is under more load.

If the power meter is anything like the G-Tech it might be a little optimistic, but probalby not by much. I have beat V-8 cars badly on the highway with more RWHP than me, partially due to gearing and the Supra hi-rpm curve, but also partially due to the fact that the air is ramming into the intercooler. I want to get one of those SBC ids now! It's cool to see how much HP you can make in different situations.

thx,

The air should have more affect on a FMIC than stock IC I think but maybe it helps even with the stock IC,

I have made some new pulls, in the first case the weight was set a bit to high due to that it was set with full tank of gas and I had only 1/2 tank when testing, so I changed that in the powermeter and find a straight line.....same procedure over again..

reading...4 0 1 Hp...

maybe this is more correct , I still think it's a bit high if you calculate at least 16% drivetrain loss it would be crank 403/0,84=477HP crank......in my world that´s A LOT!

All on swedish pumpgas....

It was cold in the air wich helped me I think...about +4 C I think it's about 38F but not sure...
