Supercharged D90 Registry

Just curious if we could get an idea/head count of those D90s running around with a blown motor from Rimmer or whoever did them. My truck is approaching 100k and after having a recent service things seem to be holding together fine (knock on wood). I guess just list your year, model, who did the work, what type of supercharger it is, and mileage, and maybe any associated notes or issues.

1) 1997 Portofino Red Wagon, Rimmer Engineering, Eaton M62, 93k, I never get over about 2700 rpm and my mechanic has had the valve covers off a said the inside of the engine looks great. Pulls like a freight train anywhere below 4th gear but is traditionally slow on the interstate.

I have the same exact set up but with 42K miles. Honestly, I am having some issues with the motor but the verdict is still out on what is going on.

Have you ever had to pull the pulley off to oil/grease the bearing?

I noticed the other week a slight squeak from one of my pulleys. After taking it to my mechanic he couldn't determine which was making the noise and it goes away after the truck warms up a bit. That said I have that exact concern that the supercharger snout needs to be rebuilt but he disagreed. I did change the oil in the supercharger at the time though.

Where do you drain it from and what oil do you use?

I use the supercharger oil from ford for the ford thunderbird supercharged model . 4 years ago a small container cost about $25 . I had the supercharger rebuilt last year and a new nose cone fitted . I had to send the supercharger to the Cali to http://www.magnusonproducts.com/ . I never had an issue with the supercharger but the miles had reached 70k so as a preventive measure I had the rebuilt done . For info on the oil fill go to the magnuson tech site .

How much did the rebuild cost? I have been contemplating this myself just for preventative purposes as well.

My mileage varies depending on conditions but I average b/t 11-13 mpg. I keep in mind though that the truck has a lift, 33's, rockware bumper, winch, its a wagon, safari roof rack, sliders, diff guards, etc, etc. I think sans all of this the mileage would be much better.

Magnuson states it is around $1200.00. I also get in the neighborhood of 10-12. That is with 35's though and some other odds and ends.

1997 Yellow D-90 soft top(obviously). I bought the Rimmer blower at 30K. Blew the motor at 80K. Got a 4.6 block and it's running good at 109K miles. I believe the motor blew at 80K because my idiot friend put 87 octane gas when he borrowed the truck. But regardeless, I am coming up on 100K miles on the blower so it probably needs some kind of rebuild.

I am still using the factory computer despite a 4.6 block and cam. I am sure that could be better optimized. From reading the RPI site, it seems like the real weakness with these blowers is getting sufficient gas to pistons 1 and 2 or the back of the motor. Has anyone resolved this?
