Lil 2.1 K.B.

[slowr w/o blowr]

Whats the furthest anybody has taken these little 2.1's on a 4 valve? I've read that they will somehow outperform the older 2.2's. Does anybody have any info on them? On the K.B. site they say they have a maximum boost of 19 psi and 21 psi. 21psi being mentioned at least twice. I am not exactly sure how much they will really do though.

Has anybody pushed these little blowers that hard yet? How are they doing?

I thought 2.1 was a 2v replacement for the 1.7??

the 1.7 and 2.2 were discontinued. the 2.1 was the replacement. it flows more and has less drag than a 2.2 per k.b. website.

You can push them to the highest recommended RPM for the blower. That cold be different boost levels depending on the application.
