Far out!
I'm enjoying Matts tune with 7 (9?), 13, 18psi (each with custom dbw maps) via the dial.
Yours is probably 7, 18, 18 (with the stock dbw throttle maps) via the dial?
Equally useful IMHO

Sorry sport is 185kw and 630nm at 17 psi so it dropped by 1.

Hi Craig. What is your fuel consumption like now? Are you using a bit less?

[rooby]

670nm. Really. I'm suspicious of that number.

I was gutted! I only got 460!

You should have made more than 460. What type of boost are you running? The 2.5L is a torque beast.

I'm surprised the stock turbo can go to 18psi.
Most stock turbos only go to 16psi before running out of puff.

Torque is a meaningless figure on its own. It depends what rpm it was measured at.

Nice results Craig and congrats on the bub!

Matt got mine running at 19 quite happily till I popped the little hose of the BOV, now it is sikaflexed on although he de-tuned it to run a safe 17.

That figure is at the rollers....it's all about dividing it with the ratios of the diffs with which gear to get "nm" at the wheels...

Like I said you really only need the rpm figure that torque figure was measured at to get a meaningful comparison

I prefer reverse engineering the wheel hp figure to get crank torque, every gear has different wheel torque

Engine Hp = (engine ftLbs x rpm) / 5252

After looking over dyno chart again I realised that 460Nm is the before figure. Apparently the real after tune number peaked at 635Nm on 18psi in 4th gear doing 80km an hour at what looks to be around 3000rpm (going by the plot lines).

Ahh, I feel better now.

And i think the stock turbo runs out of puff at around 16 psi cause of the stock blow off valve. Michael from MSR reckons they are very prone to leaking.

Engine Hp = (engine ftLbs x rpm) / 5252

Or for torque
ftLbs = (5252 x Hp) / rpm

Nah, the turbo would simply be moving out of it's efficiency range at that flow.

Oh ok. I just thought that the BOV leaking prevented the turbo boost from becoming useful.
