Car Dyno'd Drivetrain Loss Q?
Whats the number you multiply your horsepower and torque by to get by the drivetrain loss.
Got my car dyno'd and tuned today, at first I was making 246.19RWHP and 283.19 RWTorque
then we turned the distributor a bit and tried putting it to its limits, got an addition 15 horses!
And my Air/Fuel ratio was PERFECT somehow and I have no idea what im doing either.
So no need for the chip.
Heres what fooling with the timing til it was perfect got for me:
260.29 RWHP
292.80 RW Torque
Anyhoo just want to know the actual numbers the engines producing.
I think they said there was a 14% Drivetrain loss, they told me what it was but I fergot the number exactly.
nhdungeonracer was up there as well today, just came to watch my car perform and to chat a bit to the techies and such.
Was kinda eggin him on to get his dyno'd as well and he finally caved.
I'll let him tell you his results though.
Very happy though, car feels much different now! Got my estimated HP # too!
Was atleast hopin for 260
and wallah!
I think they said the engine was making 300hp and the torque was around 340?
Well can anyone post the number you multiply by?
Edit: Also gotta say if you're in the area check out Performance Dyno
They were pretty cool about everything, got 3 pulls for $50.00 and like an hour's work done for like 50 bux too
The owners got a 69 Mach 1 stroked to 393, his last run was an 11 flat(with horrible traction) at 122 mph
he owns a z06 too.
Also theyre having a Mustang day next saturday (6-12-04) 40 bux for 3 pulls for all mustangs
Going to have food drinks n **** too, might go check it out.

RE: Car Dyno'd Drivetrain Loss Q?
every car is different. there is no exact way to calculate. it can be from 10-20% loss. the only real way is to get it on an engine dyno. using all synthetic fluids help reduce the loss %
