Surely a S/C'd busa is much easier to drive and nearly as quick. I know the power isn't as strong, nor the torque. However, the linier power delivery would make the engine feel bigger rather than completely different. What I am trying to say is, surely with 300 plus bhp from a turbo you are getting violent power surges and also the peak power will be made quite low I would imagine detracting from the reviness of the original engine?

What do the costs compare like for the s/c conversions?

As I understand it, because of the primary reduction and the low boost required, the turbo kicks in well within the useable rev range anyway..

The costs are very similar to the turbo as I am aware, the TTS kit costs around £2500 without intercooler or induction system..

Mr Turbo full kit is around $3795

Ive been in Bazzers on the road in low boost settings (~250bhp at the wheels) and it does just feel like a very large capacity N/A engine, there's no lag, no big peaks in power, just a wall of torque and power thats relentless from about 3k to the red line. It might lose a bit of this when the boost is wound up further, but it spools up so quickly and so low that power delivery is never going to be an issue, its not like a 500bhp Cossie engine where nothing happens until 4k then a sdden dollop of torque before running out of puff by 7k.

Just that holeshot told me peak power was made at something crazy like 6 or 7k then held to the redline. Surely that would feel a little strange? Almost like a deceleration?

Peak torque i think he means

I hope so. Do we have a RR print outs or curves for a turbo busa?
