I would take the 600Bhp claim with a pinch off salt unless I saw the results on a Dyno. My Transmission/Gearbox, Axles etc. on my 5.0L have lasted 5 years with no problem with a pulley upgrade and re-map. Have the readout here somewhere, if I remember right the torque went up to 750Nm on the Dyno and Bhp somewhere between 60-70Bhp.

anyone know what a good replacement supercharge would be for the 4.2?

Does anyone know if the supercharger has to come out to replace the pulley?

hmmm, i did, but if you can get to all of the E torx bolts then nah.

because it is a nightmare to remove the bolts behind the supercharger.

thanks.

I see they have updated it to a two-piece pulley

actually which SC do you have? I was on about the 4.2 not the 5.0

I've got the 5L, it's a 2015 L494, 375kW version. --

The 4.2L has the Eaton M112 Supercharger the 5.0L has the Eaton Twin Votex TVS R1900. I don't recall Alive Tuning removing the S/C when they did the pulley on my 5.0L albeit a RRS1, they did the remap and pulley change while I waited, although to be fair I did not watch what they were doing and it was over 6 years ago now.

Gents, does anyone know where the filler plug is on the Eaton 1900 supercharger on the L494?

Can't find it at the front.

That's because it's at the rear.

Cheers Col, thanks.

I was wanting to change the oil while doing the pulley upgrade, but that's too much of a mission.

It'll have to wait until June, when the 7yr service is due, since it will be in the shop for a couple of days.

Had I know, I would have organised to have it done when they were replacing the crossover coolant pipe. --
