Ultimate power goals, and being able to make some use of that power...
Plus I had never used a supercharger before, so wanted to try one.
IMO, using a turbocharger to make big power from a 2wd road car( the sort of power I wanted I mean ), on a manual gearbox, and normal tyres, is a complete waste of time.
If using very sticky tyres, and an auto box, then it might handle it a bit better.
But I aint old or incapable enough to warrant going auto
At a guess my old RV8 was making about 500bhp. But when boost starts picking up, power/torque does come in with a big rush, and its very hard to control this using your foot alone. 50% throttle may as well be same as 100% throttle.
My car at the minute is of course stupid on the road now too because of too much. But it would be even worse if it was turbocharged making the same power.
I was at the dyno recently, and despite a few problems, was making 850rwhp and 750rwtq on super unleaded. But peak torque wasnt until about 5000rpm.
If it was turbocharged, this would probably have been a lot sooner.
If going for turbos, and dont want to go for mad power. Get some sort of decent boost control, that might allow you to map boost vs rpm, or tps. This can smooth power delivery, and it make it very usable on the road at all times.
And DONT go for huge throttle's If anything, downsize and go small. This will give far better throttle resolution under foot, and if you keep sizing sensible, will not hurt overall power one bit.
A std single 78mm TB on a LS1, will easily make over 1000hp when boosted..
In general though, I would go turbo every time. Id still do it again on an RV8.
