chrislane Posted February 5, 2014 Share Posted February 5, 2014 A phrase i have used more than once over the last couple of years. But a chat with Mark at Stratstones at the weekend made me wonder just how close to the standard 120bhp mine really was. So i took it along to a local rolling road this morning. I have no idea how accurate these are, but none the less it seems to be generating more power than i thought it was. Its only taken three years of ownership to realise it! rolling road.pdf Link to comment Share on other sites More sharing options...
Dr H Posted February 5, 2014 Share Posted February 5, 2014 What's the 106 in brackets? If that's the wheel power at the rollers then I'd say it's spot on. People reckon between 10-15%, losses on the Elise so if you pick the middle at 12.5% losses that's just about 120HP. If the 106 is wheel power I'm sure how they estimate 146 form that a power loss of about 27% which is too much for the Elise Link to comment Share on other sites More sharing options...
Alex B Posted February 5, 2014 Share Posted February 5, 2014 impressive, some possible previously carried out work on the engine? Link to comment Share on other sites More sharing options...
jonnyfox Posted February 5, 2014 Share Posted February 5, 2014 ^^^^ what Leigh said. If you take it to the States they reckon about 25% :-) http://www.mk5cortinaestate.co.uk/calculator4.php Link to comment Share on other sites More sharing options...

Martin R Posted February 5, 2014 Share Posted February 5, 2014 12.5% is a reasonable figure to use. Possibly slightly conservative but near enough. The differences in rolling etc means its only a guide anyway Link to comment Share on other sites More sharing options...
Dr H Posted February 5, 2014 Share Posted February 5, 2014 Id say you should be happy with that result. Looks like you car is very healthy! RRs are a bit of a black art. I've had mine on 4 different ones and got a very different figure each time. Link to comment Share on other sites More sharing options...
Dennis Posted February 6, 2014 Share Posted February 6, 2014 A decent rr operator can make them show whatever they want (especially if they have just released you of some £'s for an air filter or similar) The important bit is is your car running ok (as stated above) Now to your question, 120 in such a light car was good 15 years ago but now hot superminis have to have 200 bhp (ok they are a bit Lordy these days) but 120 does make it a little breathless once it is going. My 1999 118 k is up to 150 and it is good to have those slightly longer legs but a little more would be better but I would not want to risk it going pop on a standard bottom end etc. Link to comment Share on other sites More sharing options...
Martin R Posted February 6, 2014 Share Posted February 6, 2014 Get some 160 EU3 pistons in it. Should be good for 180 then. Link to comment Share on other sites More sharing options...

He said, do you want a headline bhp figure to brag about to your mates or do you want a car mapped properly! I'd be happy with that result Chris, looks like all is running well Link to comment Share on other sites More sharing options...
jonnyfox Posted February 6, 2014 Share Posted February 6, 2014 ^^^ very true Miles, mine is mapped in the same way. Headline figures could have me 240+ at the fly but/and having seen 2zz's with similar mods and more power none have the peak torque I have.

Eric Posted February 6, 2014 Share Posted February 6, 2014 For everyday driving, you don't really need any more than that. But what about weekends? Aaah well, that's a different matter entirely, with horse power being inversely proportional to wallet contents but directly proportional to grin factor.
