Bug/Blob with Deltadash ?
 

I am looking for acceleration figures for the WRX, Sti UK & JDM and also PPP versions.
Ideally in 3rd for the 5spd and 4th for the 6spd cars.
30-50, 50-70 and 70-90.

cheers

Andy

Andy,

Copy of 3rd gear road dyno run from last April with about 3k miles:


Dyno Test: 3rdgear080404

Maximum Wheel Power: 211.0 BHP @ 5420 RPM
Maximum Wheel Torque: 222.9 LbFt @ 4245 RPM
Power to weight ratio: 136.1 BHP per ton

Terminal velocity due to power: 163.0 mph

In Gear Acceleration:
40 - 60mph = 3.1 seconds
50 - 70mph = 3.0 seconds
60 - 80mph = 3.3 seconds

Speed per 1000 RPM:
1st: 5.4 mph
2nd: 9.6 mph
3rd: 13.7 mph
4th: 19.3 mph
5th: 25.4 mph

Maximum Speed per Gear:

Engine Rev Limit: 7100
Test gear: 3
Max Speed of gear: 98 mph

Done on a fresh full tank of Optimax

Only one of those times matches the range your'e after, but I've got quite a few 3rd & 4th gear logs that those accel ranges can be worked out from. Taken from Spring and Summer last year. Any use to you?

Thanks Nick, thats great :)

Any of the increments ie 30-50, 40-60, 50-70, 60-80, 70-90 are useful

If you select "light smoothing" you may also get the 30-50 and 70-90 figures, on the normal "heavy" setting it clips the two ends off the graph, this makes the power figure more realistic but has no effect on the in gear speeds/times.

Here's info with light smoothing -
Dyno Test: 3rdgear080404
========================

Maximum Wheel Power: 242.9 BHP @ 6035 RPM
Maximum Wheel Torque: 246.2 LbFt @ 5010 RPM
Power to weight ratio: 156.7 BHP per ton

Terminal velocity due to power: 170.8 mph

In Gear Acceleration:
30 - 50mph = 3.7 seconds
40 - 60mph = 3.0 seconds
50 - 70mph = 3.0 seconds
60 - 80mph = 3.2 seconds


33 wheel bhp at the click of a mouse - If only it was really that cheap and easy in the real world.

lol, cheers mate :)
