For the duration, the lobes have pretty high lift and open quite aggressively. That in turn means hard on the valvetrain.

Turbochargers also quieten things down.

And catalytic converters quieten things down

As said. My issue was flex leading to bending of the pins.

This was obvious, as in order to open/close the hood easily again, the pins had to be re-straightened.

Really depends.

The set you've pictured looks like a flush set to be mounted on the underside of the hood...which would probably be trickier.

But it's just a case of finding somewhere suitable...

It can only whip back so far because there is the free movement to do it, which makes it appear even more violent.

You shift at 7200 and it drops you to 4k ?

Impossible.

You'd need to be shifting near 6k to drop as low as 4k.

With my YSi I could shift at 6700rpm in 3rd into 4th and land at around 5k. This is around 110-115mph, and on the street, this just resulted in loss of traction again.

Agreed, there is little reason turbo performance will suffer at higher rpm's unless there is a major design issue.

If anything it can often help at the top end.

If it breaks traction, let off a little to try and control it.. That will be the same for turbos or YSi

Most kits ( all brands ) seem to use the cheaper pump, not the Exa. But couldnt say that for sure. Just any images Ive seen have all been the cheaper pump

The Exa is a beast of a pump.

When searching I never found a bad report about one. Lots of bad reports about pretty much every other pump out there though
