Unless your car is horrendously badly specced you wont ever have to wait for it to spool up, if you do, your in the wrong gear! If your in the boost threshold then even a modern 500bhp+ turbo on a 2litre has no lag to speak of.

For example, lets take Rod's car...

2.2litre 4cyl 16v YB, 7.2:1compression, using a fecking huge GT35R turbo.



200lb/ft, std cossie performance at under 3000rpm! You want lowdown power? lol...
200bhp by under 4000rpm too! Lag?

4250rpm... midrange, where even the most pussy drivers rev to...
375bhp and the torque about 470lb/ft! Why do you need a big V8 again?

Oh dear, look further...
The power steadily rises and peaks at 6800rpm at 614bhp and stays not far from the 600bhp mark upto and beyond 7500rpm,

Oh deary me again, torque keeps rising even more and peaks at 508lb/ft at 6000rpm, stays above 450lb/ft till 7250rpm, and even at 7500and beyond its still 400lb/ft...

That pisses over the performance a 2.2litre supercharged engine can give, low down AND high up.

And thats with a huge GT35R which is good for 700bhp! If you only want the power most supercharged 2litres would give you, ie about 250bhp for a goodun, then you could fit a GT28RS, have about 330bhp and NO LAG, far more low down power than a supercharger as well as a good 80bhp more!

Like i said, i love em, but not half as useful as they used to be...

They not bad as low boost things to fit to n/a cars, but if you want proper power it gets more expensive than a turbo and shows no real gains with todays modern turbos.

Twincharged engines do sound 100% sex tho, and the idea of getting a sierra, bashing in a lightly modded 302ci ford V8, and run 2x cossie T3s and a rootes charger sounds a good cheap idea, for the noise alone...
