Yeah, that would be a real bastard.

A mate of mine who races a rgv250 and has had loads of dyno charts done reckons there's dyno's and then there's dyno's. Figures depend on the settings for air pressure, moisture content etc etc that the programmer puts in. Comparison figures can only be done on the same dyno on the same day.

Maybe you need another dyno, Honk, to find that extra bhp: preferably one thats facing downhill.....

You are right Dave. All dynos differ. It appears that there is no Standard either. Which is the root cause of course.

There are other reasons too, atmospheric pressure, humidity etc, and crank HP is always calculated using a bagful of assumptions.

This is something I've had discussions about on other forums before, as given that my entire working career has involved various forms of measurement and test, I really struggle to understand how this situation can be tolerated. I recall being told by someone that should know better that doesn't matter but that's just bollox IMHO.

Mind you, I don't know, but I'm guessing that Honk's and Phuk's TRXs were measured on the same dyno.

Anyway 2BHP is feck all, it could even be the difference between petrol from one station to the next.

Can't recall which magazine it was that did a comparison between DynoJet centers. There were even differences on the same Dyno the same day, but with different operators... I'm afraid Dyno figures can never be really comparable, there are far too many factors affecting the actual output. (Just think of tyre pressure, tyre condition...) My last Dyno run showed that a freshly lubed chain gave some 3-4 BHP...

Dynos should above all be used for confirming adjustments... But of course it's nice to see high numbers, and maybe that's the truth behind some of the less serious DynoJet centers, they want to show the customers that the adjustments made by their workshop really brought something... With that said, I still believe Honk's and Phuks numbers are impressive as they are, but I'd rather say 100ish then 102,7

Oh quit picking on the poor old phuk... He's got braggin' rights over Honky right now, and he can rub it in! Three digits to two!

It's all about building up excuses so I dare to show my Dyno charts

But of course, breaking the ton is a classic!

The 'different dyno's' arguement is all very well and good except..... My figures are from the same dyno! Never mind.... I think I know where those extra ponies lie!

And who's bike has been featured in PB, and who's bike is the TRX of the month???

Phuk, I voted for Your

Yeah - both mine and Honk's were run on the same dyno by the same guy - Grant @ GP Performance (next to Foxes Diner).

Yeah - 3 bhp is feck all (and I know where he can make it back as well .. and that he will)

Phuk, I voted for Your

Thanks Hans - I voted for Honk's

I've seen how much work he has put into it - close up it is like looking at a work of art. Still, he can't win next month - maybe I can get the christmas special!

OKOK, so You won

I thought Honk had had enough of attention lately, but I love his bike as well. As You say, the details look astonishing!

It would be useful if you guys sat down and made a list of all the necessary mods to get to 100hp.
As it is, the details are all spread out over many posts.
A nice list with rough costs involved would be cool.
Any chance?

There is a Members TRX specs section - here's a link to mine

http://trx850.motomaniac.net/forum/viewtopic.php?t=491

Cost is very much dependant on how much you can do yourself (and to some extent who you know) but here's a rough guide to what you need to spend:

Full exhaust system - Ãƒâ€šÃ‚Â£350 for an akra system second hand (I have a system for sale btw!) up to over Ãƒâ€šÃ‚Â£700 new

Kent cams - Ãƒâ€šÃ‚Â£175

Gas flow, porting & skimming of head - Ãƒâ€šÃ‚Â£150

Big bore kit and boring barrels - Ãƒâ€šÃ‚Â£450

Keihin FCR41 carbs - Ãƒâ€šÃ‚Â£350 second hand (if you are lucky!) to Ãƒâ€šÃ‚Â£700 new.

Gaskets, oil, filters etc. - Ãƒâ€šÃ‚Â£100

If you pay someone to do it, you are probably looking at Ãƒâ€šÃ‚Â£500?

yep - it is a lot of money but to my mind I now have a bike which is not only a complete one off but it does everything I want it to.

Also, if you put it into context - the Ãƒâ€šÃ‚Â£2700 it costs to get a sorted TRX (Ãƒâ€šÃ‚Â£1500 tuning + Ãƒâ€šÃ‚Â£1200 on a bike) still gets you way more than a run of the mill boring R6 or ZX6 which will invariably be shagged and making less power!
