DaveK Posted November 6, 2002 Share Posted November 6, 2002 For any one with an interest Mick jones hayabusa engined car which defeated PC's k series @ curborough was eventually run up on Emeralds rollers and recorded a fantastic figure of 213bhp/127 lbft@ 6000 rpm. Not to shabby for an engine that is still running a std suzuki ecu. Further development with cam timing and ignition/fueling when a mappable ecu is fitted should release even better figures. Doug's caterham has also now been fitted with 1500cc engine although it runs some american webb cams which give a claimed 15bhp increase over micks car. preliminary testing has showed that top end power is definately stronger. Roll on curborough hopefully with some soft compound ACB10 to even up the fight. Dave Link to comment Share on other sites More sharing options...
R2D2 Posted November 7, 2002 Share Posted November 7, 2002 The power, torque and rpm figures don't seem to stack up. Is 6000rpm the engine speed? Link to comment Share on other sites More sharing options...
Trevor Phillips Posted November 7, 2002 Share Posted November 7, 2002 Excellent bhp figure. Was that at the wheels or calculated flywheel? I seem to remember when I was down at Doug's he said it was over-bored and had a number of expensive upgrades on Mick's car? Radicals claim 252bhp at the flywheeel from their 1500cc Hayabusa engines now. Racing pics and items for sale here Link to comment Share on other sites More sharing options...
oilyhands Posted November 7, 2002 Share Posted November 7, 2002 The 6000RPM figure is for the torque, the peak power RPM must be around 9000-9500 for the torque to stack up. Oily Link to comment Share on other sites More sharing options...
sjwb Posted November 7, 2002 Share Posted November 7, 2002 Mmmmmmmm, 145hp is nearer the 'raw data' mark. Steve B Link to comment Share on other sites More sharing options...

DaveK Posted November 7, 2002 Author Share Posted November 7, 2002 Chris The rpm figure is for the torque ,peak power was about 9500. This was the calculated bhp figure @ flywheel by emerald taking into account the losses on the RR. With emerald being a common RR , then people can reference against how there own engines performed .

Peter Carmichael Posted November 7, 2002 Share Posted November 7, 2002 That is the same rolling road that measured my big engine at 250bhp three visits running. Fixing the top end fuelling lifted the peak to 253 on the last visit; the other parts of the power curve lined up exactly over the repeat runs. The Emerald rolling road seems to be remarkably consistent and a good place to get fair comparison data. Obviously I can't explain how with a 40bhp advantage and sticky tyres I lost to the hedgeabuser by three hundredths of a second. No. Really. I am over it. I am. Not sensitive about that at all.

edmandsd Posted November 7, 2002 Share Posted November 7, 2002 It's a 1400cc isn't it Dave ? Still impressive with 45bhp more than standard, and at relatively low rpm (considering that 'standard' in bike terms is pretty impressive to start with from a power per litre perspective) Home of BDR700 Link to comment Share on other sites More sharing options...
Gridgway Posted November 7, 2002 Share Posted November 7, 2002 huh PC, you think you are hung up over it. How do you think your car feels?? Have you no empathy man? I have just been out counselling it. We've just got to "winning isn't everything,winning isn't everything,winning isn't everything,winning isn't everything,winning isn't everything" Have a heart for heaven's sake Graham Link to comment Share on other sites More sharing options...

Sheds Moderator Posted November 9, 2002 Share Posted November 9, 2002 Remind me gents, what's the conversion from torque @ RPM to power? I know the theory, that force x distance = work done, and power = work done per unit time, but I can't be bothered working it all out when sb. out there just knows it offhand. Yours lazily Steve.
