One day I'll do a pulley change on mine, just so I can tell people it's 400 or so BHP rather than 370 as that sounds a better figure. It's quick enough for me already really.

I knew I was going to put a smaller blower pulley on and an oversized harmonic balancer for more boost. Having a 3.5” MAF (and 3.5” intake tube) with very little air resistance inside the MAF means the blower has to work less due to less air restriction. However, I know that there are many, many other restrictions between the air filter and exhaust tips which I won’t get into.
