Would you like Dyno Sheets? Iahve the before and after sheets!!

Can anyone here host it for me

that cant have been a stock vtir...

i never said it was stock.. if you look back.. i said it had 98' spec 4>1's, full 2 1/4 exhaust, intake, pod.. and tuned with the VAFC.. i was expecting 110 at least, but i was stoked when it got 112kw before tuning, then after a bit of playing with the fuel etc.. i got 120KW atw..

that must be one generous dyno

thats where my dyno plot is.. Proof dude

No one doubts that your dyno plot says 120kw atw, what they are saying is it was a generous dyno... =)

But come on guys, the figures are not important... There are more important things to look for in a power curve - i.e. attaining the most linear curve you can...

Beyond Motorworks is known for not having a generous dyno figure.. but yeh, you can see my orignal curve was shit.. lost power at Vtec, then shooting up 20kw's within about 300rpm.. after the tune it feel so much smoother to drive, not noticably faster though.. i still think the vafc was a mint buy.. hey i only paid 250 for it..

I can't actually see the plot you posted... says I dont have access???

=/

Out of interest My D16y8 made 85Kw @ Wheels. Modifications I/H/E. That was with 91Ron ULP and in 4th Gear too.

Now It's just had a full service and I run 98Ron ULP. Goes Even Harder. :D

A guy that I know has been building race engines since the 70’s. His opinion is that “at the wheels” dyno figures are useless for comparing how good/bad an engine is as there are too many variables that affect the final figure. If you want to compare engines use engine dyno’s not roller dyno’s.

(I think that I was the stock DC2R that pulled 102kw at the wheels – I was just curious to see what I would get)
