Why do Star calculate losses so much higher than most other rolling roads?
They can give very misleading flywheel figures due to this.

I thought JBS read low losses at around 25bhp but Awesome (Dynojet) read even lower at 10-15bhp.
Jim Cotton (Awesome GTI) posted a very good explanation why losses are so low and why theres no way that you will lose as much power as you are seeing.

Well done anyway chief 200 atw is good going, my yock put out 165 atw although with totally inadequate blowers and after sitting idling red hot on a sunny day for 15mins :hide:

Times at Crail show she performs on the road too!

cheers mate ;)


Gary if you are questioning the RR results give Jim Curley a phone and ask him why his losses are so high. Even better go and try the rollers for yourself.

I wasn't asking for your opinion, just posting my results!" Dave's Ibiza Cupra R made 182BHP which is bang on for a standard car, so rollers are spot on. Maha is a real dyno, not like the Dynojet crap

10-15bhp - Dynojet RR, what great reputation that has..... :lol:

Im not questioning your results - 200whp is about right and must be great in an Ibiza.

Flywheel figures mean nothing anyway.

I think Gary simply posted an enquiry, he didn't say Star were wrong or run **** rollers. Which is what you have just said about Dynojet.

In my opinion, which does count as a lot here as I run the place, you should wind your neck in, and stop being so defensive, if you don't want people to discuss, debate or comment on your results, its simple, don't post them.
