I have manage to get one of my dyno sheets on here for the first time so it can be seen and not just talked about, this dyno runs was on just bp 98 pump gas and at torque performance, after trying othere dynos that could not hold it as the boost comes on so fast and hard, as you can see on the dyno sheet we were still getting wheel spin after we tryed every thing we could to hold it.

Thats a huge effort!
You may want to edit that photo, show's your rego which can be a bad thing to put on the internets. and it's huge.

try

Very nice - thats some really solid power on that boost, has a really nice wide powerband too. When/where did it do 550kw?

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.

*sigh* - makes my 240kw seem so tiny haha

See the other thing i did notice is when i went from the r154 manule to the c4 trans i lost 30kws and this time i lost another 20kws going from the c4 trans to the big th400.

You need a 1G on the back of your 1.5JZ just to power the trans hahaha

And you can see my turbo is way to small as i dont have any lag, will be upgrading very soon :twisted:

Dont happen to know what the RPMs for those kph equal?

have you got some info anywhere as to head work, cams etc etc?

no sorry, but i do know if i am cruzing at a 100kms my rev counter is around 2800rpm

by **strx7** » Fri Apr 03, 2009 11:34 am

thats in a different gear though aye?

do you know at what RPM you hit 25psi at?

This is in my top gear as the th400 only as 3 gears were i spike to 25psi thats about 1800rpm

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

Yeah he'd be in top gear on the road at 100k but not on the dyno

by **strx7** » Fri Apr 03, 2009 12:41 pm

according to a website 2nd gear on a TH400 is 1.48:1 and 3rd is 1:1

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

well the rev limit was set at 7400rpm, so cant be 8000rpm peak power.....

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 1:1
