Turbo is still Pat's old unit. 52 tirm GT wheel, 76.2 exducer, 0.7 AR cover, 0.82 AR ex housing.
On plain optimax the results were 501hp and 480ish ft-lb of torque.

I think it was around 450, that was at the wheels though 
It was 501 or 502 at the wheels with a 50 shot N20.
Anyway, don't be so sensitive, the 2.5 and 2.3 are still lagging behind the 2.2 and 2.0 !

Tut tut andy, I think the actual figure for your non nos run was more like 480 wasn't it, wih some hp lost due to the rollers not working well. Such is life with 'proven' figures!
Of most interest to me were the gains in race fuel, although I expected the optimax results to have been not as good as they were. In reality I think they need a degree or two taking out, the PFC logs show it was detting a few times on the rollers.
What was the flywheel figure for your Nos run Andy?

556 @ flywheel from memory with the 50 shot of N2O athough it was a very safe map, perhaps thats one reason my head gaskets are still intact ?
501 @ flywheel is without a doubt a good result on Optimax from that turbo, how much difference do you think your high lift/duration cams make ?
I can't say the race fuel results surprised me though ? 10% gain is still less than I would have expected from 118 Octane, it is generally accepted that 10% can be had using a splash of methanol and NF.
Hope you get the head gaskets sorted soon.

I think the Optimax map should have been in the order of about 480hp with the map as it should have been, had I realised how poor the electronic det cans were that the RR operator used. So I would put the gains at more like 15%, I was surprised at the SUL power level too.
As for my head gaskets I think they were compromised when I had the misfiring last week. The block surface wasn't great after the initial failed gaskets, spanking new gaskets, block and head surfaces should be okay for a little more.
I am not sure that methanol and NF gives an "generally accepted" 10% increase?
I have no real idea the difference the cams make, at the max power levels the turbo is by far the biggest restriction in the system. I will have a look at the logs of the 1.4 bar run which made 503hp, as that should probably give a better picture of the ariflow change at high RPM.

how else could I have been running 440bhp @ only 1.47 bar boost on my 2.0 with a 20G when it's allegedly NOT even a 400bhp turbo As a comparison, that would be the equivalent of 550bhp on a 2.5 assuming an equally maxed out turbo being the limiting factor.

Andy, i have it on good authority that your engine is not as great as you may like to portray... would you care to elaborate?
Maybe your head gaskets are not giving probs, but something else is

Don't forget andy that the day you set those figures the roller software was mis-configured. You were down at least 30-35bhp. That was for ALL the scoobs that were there on that day.
