As an example of what i was comparing it to i.e an evo running similar power (obviously different spec etc) , making nearer 450bhp at 4.5k.
Not to take anything away from the subaru as it must make for a bloody exciting drive

I didn't say it was un-useable did i, just asked if it was as laggy as it 'appears'.

Both nicely shaped graphs and excellent power either way.

sorry for the off-topic...
does the standard scooby intake manifold not become a restriction at any time? as all the high powered scooby's i see (600bhp+) all seem to be running it still....
or is it an aftermarket one that looks similar?
he obviously knows what he is doing

Scooby engine looks like it makes some good power. Not sure its fair to post up a graph from an engine dyno to compare it against. They always seem to look better with spool up than a chassis dyno.

Trouble is, even if it actually WAS 37 degrees that day (which clearly it wasnt really) that formula is only intended for use up to 35 degrees in the first place, its not considered accurate beyond that and im not aware of any other formula that can claim accuracy at those temps either.
It would have clocked under 700bhp though if the temperature probe was used as DD intended, so I guess thats a big motivation to misuse it when your so close to such an "important" figure, as no one wants to tell people their car is 690 instead of over 700
Or maybe it was just an honest operator error and they dont know how the rollers are meant to be used, just cause it happened to go in their favour so much isnt proof they were trying to be dishonest, they may just be incompetant.

I think one graph is a RR & the other a Dyno. Mine appears to be about 1000rpm later on my RR graph to my Dyno one so dont try to compare im sure an expert on here will explain why.

So basically the turbo will always look like its spooling later than it in fact is capable of when you look at the results from the rollers.
same way that a lot of turbo cars cant hit peak boost as soon in 2nd gear as they can in 5th gear.

So why is he claiming it was 37 degrees C on the day he dyno'd your car?
Dont misunderstand me though, im sure its an awesome car, and if its 690 or 708bhp or whatever will make fuck all real difference.
Ive seen AJ graphs with over 50 degrees for intake temps, so yours is by no means the worst either!
Martyn is someone I have no respect for though TBH having seen the fucking shockingly negligent job he did when mapping Neil Adam's westfield which he charged good money for the priveledge of trying (and failing) to learn about autronic at his expense.
Wouldnt have been so bad if at least when it came to light what he had done he offered a refund, but he didnt even do that.
Personally I think Neil should have sued him, but he just didnt want the hassle.
