You could also use water injection if detonation cant be avoided..
But for such relatively small gains, it's hard to see how a twin turbo install would be worth the effort. Spend the money on the stroker, better heads, cam etc. You should easily see an extra 100bhp with that.
Other than perhaps the availability of cheap smallish turbos, I wouldnt even consider a twin install again. A bigger single would be much easier in every way. Well, unless I was buying an already fabricated kit. Twins are pretty much double the work.
whats the limit of 2 bolt main small block bottom ends steve ? thats my only other concern.
its all just cheap stuff im looking at, manifolds are £130, both turbos £300 for the pair, i reckon i could do the whole job for under £1000 intercooled aswell complete twin t3 turbo set up like 2 standard cossie turbos.
or a 383 stroker kit is about £1000 aswell but i think just the stroker would just add about 50 hp. im currently on the double hump heads aswell 64cc i think but pretty sure on soft valve seats so running millers with the optimax at the moment.
