Too right mate - Well done Shaun mate...


Scooby Eater too, methinks?...

cheers matey's

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...

Come on lads we all know mine is by far the fastest here and the sexiest

Heh heh... I certainly bow down to your pristine paintwork! - 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....

Looks pristine mate lol but is a bit miss match nowadays with parts of kit ive put on, respray will be on the cards soon

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!

It would make sence for the heading to be wrong but give them a call anyway.. By all means take me out in it.Ive been in shauns at jae last year and it was rather hectic so you should go out in that too. The thing sounded like a motorbike on boost .... Either that or a few of us can get out on the track at Rockingham at the same time and have a friendly boot round with each other

to be honest jon, i was not happy with the performance at JAE last year, the throttle body switch was feckin everything up , so you will have to go for another in mine as well, mines off of the road from yesterday, its havin the cam timing and a better flowing I/C with bigger pipes fitted, i would like a water/methanol injection sorted, i will be looking into fitting my own system, which will be a lot cheaper.feck 17psi like last time jon, lets try 26psi
