I built an all alum.BBC TT 69 chevelle conv.used the Tom Nelson alien intake with 76 mm turbonetics turbos.spent 3000 on high temp coatings from the pistons to the turbos to all the down pipes.started driving the car last year and all the heat issues started coming out.car would not start after getting real hot. Steering joint got so hot the started freezing up will I was driving.fix for that was to make some boots and pack with grease. Even though I spent all that money on coatings I had to double wrap all the down pipes to fix the starting problems.it made 850 hp at8 lbs of boost.so lots of room to make a ton of HP.car drives around fine but I don't think it's no long distance car.
Just finished 69 camaro with a kenne bell supercharger ls3 .chassis dynoed it yesterday made over 700 rwhp with a loose converter at 15 lbs. Of boost.put a tighter one in this morning.this blower makes some heat but nothing like the turbo car. This car seems like you could drive it anywhere.
This is what my experience is so far with turbos and superchargers.. Greg
