HarshRider Posted May 3, 2005 Report Share Posted May 3, 2005 nice looking mini, just a shame the place he got it tuned obviously bought their rolling road from the same company who make the trials forum tape measure!!!! theres optomistic.... then theres dreaming.... the mg engine made 73bhp at the flywheel in PERFECT condition, many never made this figure.... the stage 1 kit will not add too much...., lets assume its MINT mg motor with a perfectly setup stage 1 kit.... its only ever going to make 80bhp.... which if were realistic is only going to be 60 at the wheels at best.... in reality, itll be closer to 50 at the wheels im afraid. still a nice car.... this is how mine finished the riviera run!!!! raced a 1275gt all the way from newquay to plymouth at silly speeds :D it overheated and had to pull side just as i was turning off, i got to my girlfriends house, and steam filled the air B) blown bottom rad hose :blink: aa truck home and 20mins to fix with bigmans help :) god i love minis! ← Mini Owner: It was tuned at a mini specialist and has a skimmed and ported head. When it was rolling roaded it had 70hp at the wheels, mg 1275cc engines where quicker than mini engines to start with, with a hotter cam too, so it definately is 70 at the wheels Quote Link to comment Share on other sites More sharing options...

When it was rolling roaded it had 70hp at the wheels, mg 1275cc engines where quicker than mini engines to start with, with a hotter cam too, so it definately is 70 at the wheels ← i still dont believe that at all. i know very well the mg engines were quicker, as ive said, mgs were 73bhp at the flywheel, austin metros were 63bhp (difference is the cam and higher compression ratio on SOME mg engines, mainly the 12hd and 12hf engines which had a 10:1 comp ratio instead of 9.5/9.75:1)), 1275gt's were 57bhp. its not as if the mg cam could ever be described as hot.... it falls somewhere around/just below a kent 266 all those figures are at the flywheel. to make 70 at the wheels your standard little 1275 motor would ahve to be pushing out almost 90bhp at the flywheel, which is the figure john cooper get when they fit a stage 3 head, 1.5:1 roller tip rockers, full exhaust system,induction kit and a new throttle body to an MPI mini.... your head would have to hav a LOT of work(in the region of £400's worth!) to have any hope in hell of making that power figure. im sorry, but it cant be 70 at the wheels. ive got an mg 1275 myself in my mini, with a £400 stage 3 head, full maniflow exhaust system, mg electronic ignition, hif44 carb with K&N filter, 2 core rad, lucas gold coil, split fire plugs.... etc etc and it made 82bhp at the flywheel on the rollers, which was 60 at the wheels. my engine is runs perfectly and 82bhp from that spec is awesome!!!! i seriously doubt your lower specced engine is going to make almost another 10 bhp.... EDIT: there is one option.... many rolling roads are inaccurate.... and many operators fiddle them to give higher readouts than they should... it makes sense. if u take your car to one garage and they tune it and tell u it has 100bhp, then the next time u gt it tuned u go somewhere else and they say it has 120bhp.... your always going to think the one who got the highest figure is the better garage!!!! so im not going to dispute the 70bhp figure u were given, but i will dispute that its true!

Prawny Baby Posted May 3, 2005 Report Share Posted May 3, 2005 and my mate says, "Ok well you obviously know more about my car than i do :blink: My mate has a SPI cooper with a stage 3 head and that has about 90hp and i keep up with that quite well..." I havant a clue what you two are going on about :) ← haha im not claiming to know more about your car than you do.... im jsut saying that for the given spec, the figues you have been told are very unlikely.... i wont deny that with that spec (very similar to mine) the car will be very nippy and awesome fun to drive! especially with the metro 3.44 final drive. im simply saying that i think your rolling road operator has fiddled the figures a touch.... at the end of the day who cares about bhp and top speed figures.... a std mini 1000 will show most cars on the road up given a tight country lane!
