Any results yet Kev? Mr Larrett peered over the guys shoulder at mine and I think he saw 48... But I'd like to know for sure. Also, if you don't want to put up individual results, could you just let us know the highest and lowest?

Nope, Not even chasing them at the moment.
Don't even know when the Dyno guys will get them properly documented and sent to Bernie.
I'm nt sure how Bernie is set up computer wise, but I was planning on getting them off him when I meet up with him in April and hopefully have the revised figures ready for the rule book prior to the Mallory meeting.
Then we can hopefully test a few bikes at Mallory and see if anybody falls foul of the rules

If my initial calculations are right
we are probably looking at SAE maximum figures from the Parkitt Dyno of

50bhp for Class B
60bhp for Class A
With a tolerance of 0.5%

eg 49(SAE) + 7.5% = 52.65 (DIN) + 0.5% = 52.94 bhp DIN
eg 60(SAE) + 7.5% = 64.5 (DIN) + 0.5% = 64.8 bhp DIN

Edited to get the Class B figure right

...and if anyone was tested higher than that at Brands will they lose their points?

#if they were they should take a trophy!! After that race I'm surprised many made 50bhp as engines were so hot, especially without an oil cooler

bloke said to me mine was 3rd most powerful of those tested, dont know if that included A class or just B but thnk it was all bikes...not bad for an old road bike with just a jet kit & filter

Think mine made 50.02 SAE which is high 53's DIN

jeez, sounds very good especially if hot after the race, not that I know much (only what others tell me!) but hot engine can lose what, 5% or more of power?

expect mine on a warm run would be 51ish if 49 hot

[Jolley]

Sounds like there will be a lot of people losing points

No Ron they won't as the Dyno used was an unknown quantity

But any bikes that did come out high will be first on the list for testing at the next available session and subject to the SAE figures and conversion figures generated by the Brands Dyno testing.

I ammended my earlier post and as far as the Parkitt Dyno goes we will probably be looking at a Class A figure of 60bhp (SAE) and a Class B figure of 49bhp (SAE)
I say probably as there is no intention of changing the stated limits in the rules which are Dynoject corrected DIN figures of 65bhp for Class A and 53bhp for Class B. Its just a matter of making sure the correct figures are used and applied to everyone

Most Dynos read slightly different from each other to be on the safe side your better off with one that reads slightly high, others will be quite accurate and the remainder will read slightly low, these are the ones that could land you in trouble, as you could have more power than you think and when tested at the track fall foul of the rules

When the figures were incorporated into the rules they were considered a fair amount of horsepower that should be acheiveable by many and although money and a good tuner could get you more the series is not about who can afford the best tuner its about being the best racer and having a even and fair playing field

as the rules say
***Dyno Testing – when available the intention will be to Dyno test the top 3 finishers in each class and a few at random, if tested after race 1 you will not be tested again after race 2 instead the next highest finisher shall be tested.
Dyno testing is carried out at the bike owners risk and refusal to be tested will result in disqualification from the results for that meeting***

As such Dyno testing will take place on hot engines and if anybody is getting their bike setup on a Dyno it makes sense to get the jetting/fueling suited to a hot engine as its a race bike and will be expected to run hot.

It doesn't matter what it makes when its cold as thats not how they will be tested and I for one wouldn't want my bike run up on a dyno for full power runs without a bit of pre-warming

why run an oil cooler if it doesnt make much difference? I'm thinking of the difference between warm - start of race - and steaming - end of race

i dont have one fitted, but have one to go on, and if it doesnt drain the power when hot then i wont bother, if hovere after 4/5 distance I'm losing 5% or more power I will....and most seem to have then fitted
