Performance figures

Go to your local recycling centre, pay £5 and collect your ticket

In answer to your original statement, I think we are looking at an accuracy of 95 - 98%, which in my book is good enough for pubs and forums.....

Cheers,

Is not so much the figures but ultimately is how much you enjoy driving it and how good it feels to you.

Very true, Have you got any details on the turbo you are using?

It's posted on the forum in a few threads I did some digging on it, it's midway in size between a 3071R and a 3076R.

Key difference is the choice of compressor housing and wheel IIRC they use the 6 blade not the GT 7 blade. I'd have to recheck my info.

cheers Jamo. Bit pie in the sky for me until the wedding is done in august

Chill out FFS!!

I will type it again in plain english.

A Gtech is ok but will never be 100% accurate.
Therefore, take any figures with a pinch of salt.

If they were 100% accurate, why do magazines etc spend thousands on Datron or similar equipment?

I really cant put it any simpler than that?!

God you lot on here are bloody highly strung sometimes!

Nothing is 100% accurate, but what is good/accurate enough to post at a forum like this?
And people using wrong car weight has nothing to do with the accuracy of the G-tech. Same with expensive hardware I'll guess: garbage in -> garbage out

Greg, here is the fact sheet. The turbo fitted is the MD357. Hope it helps it don't mean a lot to me....

Thanks means a little but not too much.

Took the UR out again today with the Gtech finally managed to work out how to show the tables on here!

Had to turn the boost down as the surface was damp so these runs are at 1.8bar

The red one indicates wheel spin while the black one doesnt but fluffed the gear changes as can be seen by the longer flat line between speed increases.

All done on a private road..

Would it be possible to perform a hp/torque measurement with the gtech (from 2000 rpm-7000rpm) in third gear, would be interresting to see the torque profile.

Very nice numbers!

Thanks, I will have a go. Interesting looking at the graph if i raised the rev limit by circa 200rpm (i wouldn't need 3rd!!) and didn't fluff the gear change, recon i could do a 3.5ish to 60. Happy with that...

That's seriously quick Darren, shows the advantage of less weight! DO you have a torsen centre diff or is it open? Might help a little with the wheelspin?

Cheers, Its open but locked for the run if you know what i mean..
