Why not give it a clean so you can see what you are working with and don't get dirt everywhere.

The whine from the SC must be pretty cool though.

what you tlaking about it is clean from what it was,

nar it dose look go,, and sound even better, every time we start it the nosie puts a simle on every ones faces so worth it

Gotta love the noise of the Ol GMs

Detroit two strokes don't rev harder than any other automotive diesel. They were factory governed at either 2100 or 1950 rpm. Some late 8V71N's were set at 2300. In fact they have better low speed torque than any of their competitors.

I've been looking for a manual 2L tdi. Problem is the only manual ones sold here were 4motion. It's rare to see one second hand and they're usually sold within days, sometimes hours of being advertised.

I drove a Seat Leon (golf with a different skin) powered by that 1.4 without the turbo or supercharger around the Czech Republic. For a 1.4 it was quite impressive, had no problems with the 135+ on the motorways there and used 7l/100km when driven at 130. I managed to make it use 8 litres for one stretch.

The Eaton superchargers don't whine like the old roots blowers. The rotors are angled, make the air displacement smother. I doubt he will even hear it on the 4.2.

wish i could open my bonnit and see one of them chillen on top of my engine on day

Nice one, looks like its meant to be there. Even if it runs out of wind in the top end you should see some gain in low/mid range torque.
