Paul - nice result on the grif! She looks in great condition, must be good to know the engines in top fettle too
Wish i didnt need a boot for work, a grif like that would be just the ticket for summer....
Chim, ahem......Wish i didnt need a boot for work, a grif like that would be just the ticket for summer....

Academy car power sounds about right. I think I've heard of other peoples dynoing at a similar level. As for the change revs, you can try changing at 6800 if you want, but I wouldn't bother if your in 3rd. It's totally gutless above 6000 I find!
Can't say i've noticed that on mine - you'll have to take it for a spin at some point, see what you think... Excellent result on the Chim!
I also had a result at SRR in my V1 STi Scoob. Supposed to be 250ps new, made 260bhp (if a bit laggy) and was *completely* standard, not bad for a 16yr old car.
Tried a chipped ECU and no different....however since then I detected a leaky up-pipe and fitted a sports cat. So I suspect I will be running slightly higher than that now.....There only one way to know though!

Oh, and for those that wonder what sort of stuff we dyno when not doing power runs:

Couple of Points
1) Pauls Chim is the best standard 4L I've ever done, and I've done about 200 of them (thanks for the cheque Paul)
2) The 460/470 I quoted for the M6 was because it was running normal unleaded, On super the V10 almost always does 500bhp.
What a charmer! 1) Pauls Chim is the best standard 4L I've ever done, and I've done about 200 of them (thanks for the cheque Paul)

Great thread had me beaming as I read it not too often that happens.

Big fan?
There's a bit on the BBR (MX-5 turbo and tweaked BMW Mini tuners) website where they mention not to rolling road forced induction engines due to the lack of air compared to when the cars are rolling.
Rolling road forced induction engines isn't a good idea?

Probably more air than you'd get driving along

I'm wondering why mine seems to be producing so much power now?
My Chim 400 spent a few hours in the company of Mark Adams a few years back and he managed to get another 30 bhp out of her, the result...................239 bhp @ 6100 rpm.Probably a bit less now as the cam is 110,000 miles old
Is the 370z a chain-driven engine? I understand a difference in the age of a chain can move the torque curve and increase top end (indeed on my Merc the valve timing figures are quoted along with the age of timing chain as a constant). It's interesting that 4th gear gave a funny reading in the M5. Bizarre. And just goes to show you can't believe any old dyno figure .
Good idea for a feature.
