| Post subject: | Turbo vs Supercharger |
Hey all, Im thinking what I should do to my round nose. Its going to have a bored out 1275 (probably to a 1340) with a 40mm weber, camira disks and zeemax style bodykit .... i want to get a bit more power out of it. So the question is ... sc12 supercharger (or similar) ... or ... a turbo setup? Tell me what you think Lucas |

Disregard this post ... i think im going to stick with the supercharger idea 
Although a supercharger and turbo together would be scary .... argh! Cya |

A 1340 is not really a good size for forced induction.... not enough meat in the cylinder walls Well, that is the theory.... feel free to try it though.
Maybe a crossflow head would be better? Harder to find... but maybe better |

A 1340 doesn't exist... A 1275 bored to +.060" is really a 1330, people used to race these in the UK's 1340cc limit class which is where the confusion comes from.
Probably is OK to blow or turbo, but I wouldn't go bigger bore that. Stroke it if you want more...

when i was setting up to sc my 1275, it was at standard bore size and he said make sure it stays that way, the more meat between the walls the less head gasket problems

so is it worth supercharging the 1330 or would i be better supercharging my 1100 or the 998 engine I have? |

turbosuperchargers are not new - have been about since the 1930's mainly in aircraft and mainly to supply air to these monstrous 27 litre monsters. Yes was for power but mostly for getting as much of the thin air up there into the motor otherwise plane would stall. I believe(well until recently me thinks...) a 1945 vintage bearcat pushed the 650 mph at sea level in the turbosupercharged guise. P-47Thunderbolt used 2 superchargers fed from 2 turbines for 4700shp - pretty amazing stuff Whats this got to do with minis...hmmm well would create a mad car for one but where would you put it...lol Will be good to see when done...

1500 HP, 85 PSI boost (5.7 Bar), 1.5 litres V16. This used a compound SUPERcharger and went like stink, though not for long. http://members.madasafish.com/~d_hodgki ... -e-V16.htm |

it's a rare one so it fetches a fair amount.. but it's all relative i suppose. Quote: Available from Adelaide?s Yahoo Motorsport for AUD$4600 (plus ADR-ing),
damn skim readers it's a bit much for just over 100 hp.... may aswell fit a GR "super street" special
mind you, .. it's a freakin light engine to keep the car under 800kgs
