Can't upload the graph for some reason.
But figures were...

(on the hub dyno)





273bhp
230lbft
19psi boost
18 deg advance
Normal fuel.

That's at the wheels! It's been suggested to me losses of 10% from flywheel.
So first thoughts are its making around 300bhp. But torque is instant and doesn't tail off, no lag!

I will run it on this for a bit...then we might try some race fuel. [blackeye]
And fiddling about to see what else we can liberate. [clown]

I can see I have 200lbft by 3000 revs [thumleft]

Power builds more slowly, as the turbo kicks in.
I'll sort out the uploading tomorrow.

The hoses go with a band don't they!

I though I had well and truly broke mine the first time one went!

Probably much the same as when this happened to my old car on the dyno

I will let you know when I do, lol

Dave Rowe said to me
'don't take it out in the wet, you're gonna die' [blackeye]
He commented that it feels amazing because the torque is so instant.
I reckon it'll be a dream on track!

awesome Toni
is it gonna see JAE?

what does it rev to T,
It'll be fine in the wet just more entertaining thats all
High powered SC lumps to tend to spin the wheel up easy with the instant torque, but yours should be easier, i never had a lsd,
but they do sound awesome
even better with a turbo on it though

No it won't make JAE, got some further fettling to do and maybe another map.

Dave dialled in a 7200 rev limit. No need to rev the nuts off it with the torque we're getting lower down!

With the Quaife LSD it should be entertaining. [clown]

BTW I found out my HKS stroker kit makes my engine a '5ag(z)e'.
For those interested
http://forum.9000rpm.co.za/viewtopic.php?id=1761

11.6 compression and ability to rev to 10K...I didn't know! Might have to up the game a bit. [blackeye]

[Twisted Evil] moooooore booooooooost [Twisted Evil]
I didnīt write that the devil on my shoulder did

So 18deg ign advance at 1.3 bar, with what intake temp and what has your compression ratio ended up at with all your bits? [Mr. Green]

I would imagine comments would be similar to mine:

'shut it down I'm getting a headache!'
'God that's rich!'
'What did you say?!'
