Scottish Elises

Got the Honda Elise mapped on Friday (see testimonials).

Here's what the bad boy is producing now at the wheels.

Standard non-JDM Vtec. Looking forward to driving it soon (thanks to Craig Moncrief Cars )

Nice one, around 200bhp at the flywheel then?

That'll be a lot of fun.

169bhp? 118lbft?

At wheels or flywheel?

Pretty sure the mainline Dyno at HQ is at the wheels hence my rough conversion to flywheel hp.

Also pretty sure it is a conservative Dyno too. So good power and torque.

Clue is here Campbell.....

Is there a general conversion (for Elises) when calculating power & torque at wheels versus flywheel?

I have a power graph for my S2 K series from F1 Automotive Bolton and, reading their site, their interia dyno calculates at the flywheel and mine is 162bhp and 141lbft.

Approx 20% to allow for transmission losses etc gives a pretty accurate figure usually.

Well stone me.

Long week.

Thanks.

Dave should obviously definitely buy one now.

That's perhaps a little high for a modern FWD (but in the middle) gearbox.. The VX220 gearbox (GM, triple shaft 5-speed) seems to indicate about 15% transmission loss is about right, although its not quite a linear relationship throughout the graph!

I like the sound of 15% better

15% is what I used to get the approx 200bhp at the fly.

Is that the final map??? Or just to get you started????

WankR made 223bhp and didn't have a dip in the midrange. Also, my vtec came in at 4Krpm
