The 550kws was at speed source about a year ago, what we did with this dyno tune is take so timing out so it was more safe and relible, Robin at torque sad if we could hold it better there would still be 550kws with less timing and 2.8psi boost more.Lith wrote:Very nice - thats some really solid power on that boost, has a really nice wide powerband too. When/where did it do 550kw?

no sorry, but i do know if i am cruzing at a 100kms my rev counter is around 2800rpmstrx7 wrote:Dont happen to know what the RPMs for those kph equal?
This is in my top gear as the th400 only as 3 gears were i spike to 25psi thats about 1800rpmstrx7 wrote:thats in a different gear though aye?
do you know at what RPM you hit 25psi at?
strx7 wrote:25psi at 1800rpm holy sh1t, that was with a T72 or something wasn't it?
is it a ball bearing turbo? how much headwork has the engine had done? I assume its at 8.5:1 compression
if you're doing 2800rpm at 100kph, it means you're making that 500+kw at 4760rpm ???? and peak torque would be at 2800rpm???? something not right there somewhere

Dont happen to know what RPm you're making peak power at? I'd would have though it would be around 6500-7000rpm.
you're running a 3.7:1 diff and tyres would be approximately 1.9m circumfrance???
which means if that run is in top gear peak power is a 5500rpm, if its in 2nd gear peak power would be at 8000rpm
Yes the turbo is a t72 none ball bearing, the head as had a hell of a lot of work done to it and my compression is 8:7:1 and the dyno run was in 3rd gear at 1:1strx7 wrote:25psi at 1800rpm holy sh1t, that was with a T72 or something wasn't it?

Put it this way at the drags i just drive off the line and still get 1.5 60 footsaudi man wrote:Yes the turbo is a t72 none ball bearing, the head as had a hell of a lot of work done to it and my compression is 8:7:1 and the dyno run was in 3rd gear at 1:1strx7 wrote:25psi at 1800rpm holy sh1t, that was with a T72 or something wasn't it?
