clay99 got exactly the same if you look at his graphs, is his wrong too?
his whole torque curve is a bit earlier in the rev range which is why he got less power.

nope 300lbs/ft is too much for a standard clutch IMO.

My standard clutch was slipping badly as soon as I put the GT28R on and turned the boost up. It was fine with a standard turbo at 1.2 bar.
I'm using a Helix organic now.

I'm with matty on this one.
Torque too high.
U can't compare against my graphs, because of the lack of headwork. Headwork changes the proposition completely.

Or maybe it's just running really well? Anyone ever change their spark plugs, engine oil, gearbox oil, clutch, turbo, boost controller and god knows what else all days before going on the rollers? I hear it can give some great results! I also have less heat soak than most other coupes, due to no undertray, no aircon, location of air filter, empty space in engine bay, etc.. How come everyone is saying my torque is too high, but nobody commented on clay99's results when he got the same torque as me with the same spec as me at the same rolling road a week before? Are the rollers that they use taking wrong torque measurements? (due to 3rd gear, 4f mode, whatever) If so, fair enough, but that's a lot of coupe's all down on power from the last RR day there a few weeks ago! And how can my torque be too high but my power be right when they are linked by a constant formula? I've checked it with a calculator and the figures are correct.

Well, for a start he's running 1.4 bar. Although his car isn't holding boost that well either given he's got an AVCR.

not at peak torque he isnt. he's hardly running any more boost than me at peak torque, and his fuelling is worse.
If I ran 1.4 bar at 4000rpm I'd still have 300lb/ft.

Why don´t you use the undertray? Because it didnt have one when I got it, and they cost money

as long as you are happy with the way it drives on the rd, thats all that matters, all the rest is just numbers.
they act differently on an rr than the rd anyway, so you never get the exact right result imo

well done matt! I agree about its how it drives thats the important thing and that it fuels ok. pub figures are nice, but they aren't the be all and end all!

The look on his face when they told him what it was running was priceless though.

I hope craig doesnt mind me saying this, but i told craig after the first day, that the figures were out.
Craig's initial figures, for his setup just don't add up.
Again with these ones.
There is few GT28r graphs to really check, but generally without headwork they dont break 315-320, even with mapping.
Ben20vt's coupe was mapped at PT (cat in exhaust i know) and made 314 (iirc?) so for your car with a plug/play chip to make 322bhp is a miracle anyways. Then add in the torque figure, it just doesnt sit right.
Btw, i did say to matt that i didn't want to comment, but he insisted, so here is my opinion.

Cheers Ross, if these rollers do give out inflated readings to everyone, then I cant defend that
