If I were to turbocharge a naturally aspirated MG lump, how much boost do you reckon it would run? It doesn’t matter if it pops as its a trial. So far I have got 4 psi going through mine using an intercooler and was just curious as too how much it could get.
mines an NA lump… actually got it running for a while 2day, 4.5psi atm…once i get it all sorted im gonna see how long it lasts at 7psi… Poor gearbox!
apparently if u can get it to 10 psi it’ll give a good 130bhp
The thing with the normally aspirated MG engine is it runs a 10.5-1 compression ratio, this is going to limit how much boost you can run more than any other factor.
A well built Turbo motor with decent cam, head & intercooler + 10spi will put you around the 130hp mark.
