Nick - no offence mate but the fact that you weigh around 2/3's of my body weight makes a HUGE difference!

I think you're weight helped you get out of corners and off the line better. Well that's what I reckon anyway.

No doubt about it dude.
Monty gave me some power to weight figures and it worked out the equivalent of about 4bhp over the donut munchers.

I could've done with some more weight at Donny tho!

Peak horsepower can mean diddly ****.

Power is not the be all & end all - as Geoff has proved.

Geoff won the series - well done mate

Its all down to good riding too.

Best prepped bike could be at the back, if rider not good enough.
Andy rode snot with 48 hp at Cadwell first meeting and was 6th & then 5th - A bike running far less then many behind it.

Same scenario: Andy cops a 2nd & a 5th with the Snot (now running 620 & 65hp) at Donny - Doug as a complete newbie rides the same bike at Brands, comes in 30th in each race.

Experience is what counts

I'll shut up now, and leave you to it



Alan

Well said that man!!!

At the end of the day I still managed to beat a bike with 10% more bhp at Cadwell without spending a penny.

Well done. That's one hell of an achievement. At your home track too? WOW!!

As CK said I had my bike on the same Dyno as Rattler, Pscyhlist and Senna3 all there on the same day.
My 583 knocked out exactly the same peak power as Senna3's 675, making mine just as powerful ! that is until you looked futher down the rev range where the difference grew to around 5bhp in favour of the 675, so its not all down to peak power, more to do with power under the curve, sometimes a bit of top end power will be traded for mid range grunt, quite often the case when Hi Comp pistons are used without any cylinder head work as you get a bigger bang for your fuel load but outright power is still limited by the flow rate through the head.
Be interesting to know how a 68bhp bike differs from a 62bhp bike and the 65bhp bike, may just be down to a well designed exhaust that scavanges well matched to perfect fueling, something AK spent a lot of time trying to find.

Don't tempt him!

[AK]

hmmm, dont tempt me.


I happen to have a turbo technics T2 renault 5 turbo sitting in the garage........... shall i not fit it to my road bike now, but keep for a long straight somewhere?

to supercharge would be better as you would have the constant power

skids you are totally right about the mid range, that is where on a like for like rider basis, the bike with better mid range will come out tops every time.

Skids and AK....I can't get my head round all this "mid-range" power stuff....I can't remember a single corner of a single race at a single circuit where my rev.counter went below 7000 rpm!!!!!! On the road, on an A-B "squirt" I can understand the advantage of lots of squidgy torque, but I don't see that happening in anger on the track!

So...peak power for me every time please!

Just maybe he won at other tracks too

Some people will always blame their bikes or the track, whilst never realising that it could be the rider........
