i see the 442bhp yes, clear as day.
although it states that that is flywheel power, not at the wheels. (as thors r.r usualy read flywheel power) cant remember how much these things lose through transmission now...

- Mine's right f*cked...  Cheers Rob! - Yep 442 at the fly equates to more at the wheels - most places factor in an 18% transmission loss on older r/wheel cars like the S12... Haven't got a calculator, but 442.5 *1.18 should give the answer?... (Just checked - 521.56) - close enough....

That flywheel conversion makes no sence to me whatsoever lol. You cant gain power through your propshaft and diff
 With an 18% power loss through transmission drag you would run a wheel figure of 362.85bhp. That is still an awesome wheel horsepower figure and flywheel figure though. Unless the Rolling road operator has got confused and that graph is the wheel figure like on most rolling roads. Ie they worked out that figure to be the wheel figure off the flywheel. the graph states otherwise though

sh*t! - Sorry Rob/Pukka - That's a good point - I'll check, but it was Thor themselves (Peter and Lyndon) who worked out it had just made 520bhp (Same when it made 419 on the last graph - Lyndon had pointed out that the figure was from the wheels - then told me that that equated to just shy of 490bhp at the Flywheel) - It may be the "fly" heading is wrong - Forgot about that, but I'll check with the guys - It was a hub dyno though, if that makes a difference on why the heading says Flywheel? The calculation was me adding the 18% back (I see the confusion given that heading), but I'm 100% certain that although the top heading does indeed say "Flywheel", the figure was measured from the hubs, as it's where the measuring equipment was attached! - Hence they had a known figure at the wheels, then added the loss back in to get the verbally quoted Flywheel figure... Hope that helps - I'll double check with Thor tomorrow, as my rep's at stake  , but I already know the answer... Come to think of it, I reckon the true test will be to take Pukka (as he's a kosher unbiased kind of guy ) out in the ol' beast, drop the clutch, and get some proper feedback regarding how many horses he reckons she has!

Yep - My f*ckup on the way round - That should have been 442.5 at the wheels equates to 521.56 at the fly - Still yet to confirm that Thor's heading was wrong!

but it would have been funny slaughtering them underpowerd moters
, surely you can have an external wastegate fitted, mines only a t 3/4oe, but got an external wastegate, i wun't be without one now, the noise exites me ,den, that silvia when you took me out was a beast

- we'll do it again matey - I didn't order those bloody calipers though - Will do so tomorrow if I can - D'oh! (Got my replacement studs from Nissan though!  )Good news! - I checked with Thor, and Lyndon said that the heading IS incorrect for my graphs, and that the figure for the flywheel should be calculated by using a multiplier, which they don't use for most setups. Thor therefore normally leave it set to 1.0 (i.e. the same amount - What it *should* be for my Silvia is 1.18 (i.e. 18% transmission loss (it's the figure that reads 1.0 on the graph, and is called TCF - It's to do with the transmission loss calculation, to put the extra horses BACK into the equation, as Thor measure power from the wheels.) Hopefully that clears it up! - So, as I say, I deffo had at LEAST 520BHP when the graph was printed... ( Incidentally, Lyndon mentioned that he's ordered himself a Hyper-bearing turbo for his Supra, which he says starts making boost from as little as 1,000rpm! gimmee sum o' dat! )
