Anyway, a bit about my car and the supposed problem. I bought a completely standard 97 Rover Mpi and have gradually added a Stage 3 tuning kit from Minisport, with a few parts a bit better than their standard lot, also fitted the car with a 52mm throttle body. It went back there to go on the rolling road and came back with 91bhp at the fly (the tester said he could have squeezed a bit more out of it although it would have been a bit fussy around 2k revs), overall he was very happy with the engine. What surprised me though was the loss from the engine to the wheels, which were reading out at 48.5bhp. I thought this to be quite a large loss, as the percentages I've heard thrown around for the loss being quite a bit less than this. Since then I have heard a few people say it does happen sometimes, so yeah... Now I'm not going to get into the number chasing game or anything, but I was wondering what stage of tuning I could go to to try and reduce this a little, and if it actually is worth trying to do so. I also don't want to throw a lot of money into new gearboxes etc if I'm not going to notice much difference. So if anyone has gone down the same route, I would really appreciate some feedback on what they did and ultimately their results. Thanks in advance!
