What is better a supercharger or a turbo

[wizzer]

As far as I can make out both do the same job but which is better as an upgrade for a NASP engine a supercharger or a turbo?

(Yes I have read the articles on fitting a turbo and I know it's quite hard and costly but still want to know which is the better forced induction option.)

Both , but I would say a supercharger is an easier diy proposition, all you need is some brackets, a drive source and a bit of plumbing.

With apologies to HDi fun

Supercharger - instant power at low RPM with very little or no lag. Struggle to provide big power at high RPM.

Turbocharger - Very little power at low RPM but almost unlimited power at high RPM at the cost of low RPM lag.

Combine the two for best of both worlds

Very simplified explanation.

Both sounds enticing.

Assuming the engine internals can handle it...

Strength of Internals are far more relevant to turbos as a turbo increases the max bhp and torque substantially and more importantly produces lots of heat = more stress
A supercharger doesn't do this to anywhere near the same extent . It mainly makes more power from standstill and through mid range but an engine won't get stressed by that. . Also a supercharger doesn't produce heat like a turbo .

It's hard to choose which is better really. They work differently and it's clear that the two complement each other quite successfully in many applications. It's a bit like asking if Pepsi is better than Marmite.

Anything that compresses air will increase the ambient temperature ,just touch the workshop compressor pipe to the tank.

IIRC belt drive Supercharger equipped Toyota Carollas had intercoolers.

my intercooler gets hot on the intake side at anything over 2000rpm, .

Of course anything mechanical and/or compressing air generates heat to a degree.
I meant that a turbo systems generates more heat and it is usually nearer the induction so probably matters more

Even when you pump up a car tyre, the pressurisation of air makes a large amount of heat in the pump and air line.

It's exactly how diesel engines work.

hello,
there are a good article who explain with dyno result .

That's a good read
