Sun, 18 January 2004 05:09 the only real reason for the extra hassle and weight of a twin charge setup is to get rid of turbo lag, and have torque at ALL revs (imho). this also means you can run a much larger turbo, and have it kick in earlier, than it otherwise would, since you are making more exhaust gas from the SC. if you are purely racing, the complexity of having the SC kick in if the turbo came off boost would be a bit tricky, and possibly make car control more difficult. i think a turbo only system would be better where sustained rpm is normal. for around town tho, when revs are often at idle, and a turbo is likely to be off boost often, an SC will definitely liven things up a lot!!. 80% torque from idle upwards, and THEN the turbo kicks in what could be better??? it also helps if you have a very wide rpm band to work with... if you are sticking less than 6000rpm, you may as well saty SC, but if you wanna wring out the revs, then SC is too inefficient. so, my ideal setup (for TC) would be SC overspun to give maybe 14-16psi up until 5000rpm, then switch out, and then turbo to kick in (well, progressively while SC is still on) and take it to 8000-9000rpm with around 20+psi.... hmmm, if i ever have a few grand and a few months to spare, might knock one up for the heck of it... my 2.5c Cya, Stewart [Report message to a moderator]
