In other words, I never believe the figures from that tuner's dyno (or take figures literally from any dyno readout.)... He even had an unopened (edit and bolt-ons) SS reputedly putting out 300rwkw!!! I don't think so!

Correct me if I'm wrong which car it is, but I think he was talking about the Black GT which was also at the AME show, it ran 307 rwkw on the same dyno as the boys from G&D ran their 502 rwkw LS1 (forced induction) but no one is doubting their claim, I actually saw the 502 rwkw run.

The 502 rwkw is almost unbelievable. I've seen blown LS1s getting around 350rwkw (with owners asking for more real estate) at the various dyno meets.

There is a formula for calculating strip time based on power produced, which factors in the car's weight. I dare say, if the car fails to achieve a time... then it aint putting out that kind of power.

Btw, Chris' record breaking Boss BA ute (12.3s unopened) is putting out somewhere in the order of 243rwkw - straight from the horse's mouth - there is a thread on the other forum titled 'how much power you got'... or something like that.

Horsepower sells engines (and that's what a lot of tuners try to do, rope you in) torque wins races and if your car aint producing the times it aint got the torque and power is a function of torque.

Sorry my mistake it was 502 rwhp. I apoligize for the wrong info

:D

Chris has upped the rwkw figure I beleive to acheive his lastest numbers, He has allways been the first to admit that he chases tourque rather than horsepower, which is one of the reasons he leads the Boss time sheets

Ah-ha... so the Boss engines are punching out 297rwhp! That's more credible! :lol:

Seriously there's astronomical figures being bandied about. Your choice if you want to believe...

I'm just a simple sort of a fellow. If that engine hasn't got mph on its side it's not quite producing the goods. The weight factor shouldn't have that much bearing on the Boss' terminal speed (I use results from a few Statos as proof) although it is a fair handicap to the LS1 Commodore V8s.

The Boss V8 produces enough grunt for most!

I know dyno figures can vary quite a bit from dyno to dyno, but I can't believe 307 rwkw because it's a boss, but on the same dyno that recorded 502 rwhp because a LS1 did it .

The LS1 boys have been playing with the edit for how many years, maybe 5 and it was just this year they cracked an 11 "unopened", ford have had the edit since the start of the year and are getting reasonbly close, so who knows what is possible.
Advertised weights for the XR8 ute are heavier than what Holden advertise for their statemans, (close though) so what mph are the "unopened" statos running, there been a few XR8's getting 108-110

just a link to the figures

sorry can't link it, just type the address just add .au

That's just it, people reckon its all about edit (in the case of the LS1s) when I don't think its that simple. People (tuners) have been very crafty about ways in which they've made that power. Things like U/D pulleys, stallys, semi-slicks, OTRCAI, 1.8RR, CR increase, etc... Not to mention running underweight by as much as 150-200kg (err, interior gutted out and the whole exhaust system jettisoned) at the strip.

This is the thing that peeves me... people claim a record but all they are doing is merely shifting the goal posts. The Ford boys are really learning from the LS1 boys in that area and it has nothing at all to do with engine development.

The dyno has its place but there are many tricky ways the dyno operator can fudge the figures. The differences can be as great as 50rwkw. Anyway, I know many people are excited about high rwkw numbers... I don't want to change their mindset, just pointing out the holes.

There's a couple of sub-12.8s Statos running 106+mph. One develops a measly 212rwkw, the other I'm not sure about?

For every 100kg of additional weight, the rule is (roughly) a penalty of 0.2secs will be added to the time at the strip. So using the Stato and XR/GT weights as a comparison is really a close affair. Don't forget, weight can also play a favourable part... getting the suspension to rock on its rear tyres at launch could nett you extra traction...

Got to agree about the suspension part, not many of the XR's that I have heard of have had done any suspension changes to make it react quicker, ie 90/10's.

their 60 foot times have not been that great due to limitations in the software to use a higher convertor, but that issue has been sorted out about a month ago
