Day at STEALTH RACING

Went to Stealth Racing to day to get a newer K-STAR fitted as the previous had a few niggles

Here are the graphs as you can see SWE33T was the engine after 1500 mile rebuild and the
OHS 91Y was today.  We where a bit confussed to why there was 10bhp differance then Vince twigged the wheels have been changed now loosing 28 BHP through transmission  instead of the 38bhp on the original run the @ wheels figures are still the same 143bhp

Bhp


Torque

So the wheels were changed and the transmission losses reduced from 38bhp to 28bhp?

And the K-Star and 1500 mile running in added no power (once the change in transmission losses, was taken into account)???

The wheels where changed and the transmission loss was reduced and the bhp at wheels was the same.  The engine was mapped with K-Star at 1500 and now it is 3500 with a newer ECU.

We need some updated pics of OHS 91Y !

So the car now produces less power with the new ECU?

eg say before it measured 110 at wheels, 40 transmission loss so must be providing 150

now: 110 at wheels, 30 transmission loss, so power is 140

Same dyno? Just the increase in mileage, and K Star replaced with new ECU? What is the new ECU?

The power at the wheel's is the same,  the newer ecu is still K-star ecu just a newer one

that's that cleared up then!
