The main reason for supercharging it is that my MU has no power down low.
Especially on the beach trying to turn my 33x12.5.15's.
I've Got a Toyota SC-14 Supercharger from the older MR2s, it has a 1440cc capacity (or 85 cubic inches). The supercharger also as a self contained oil system so its nice and clean.
I've also changed my oil filter mount to the larger 4JB2 style with the filter facing out the bottom and the larger oil cooler.
I've mounted the Supercharger Where my aircon pump used to be and have purchased a longer Vee belt to drive it and have manufactured an adapter bracket to attach it to the original aircon mounting points. the supercharger came with the original intake and exhaust(to intercooler) manifolds so i have been able to use both of these though the exhaust manifold is still awaiting further modification to link it up to the throttle body (valve) before going into the intake.
I have the intercooler off a Trooper on my truck, and want to cut a hole in the bonnet to allow airflow and room for a 10" intercooler fan, does anyone know what the rules are with reguards to making bonnet scoops? and cutting holes in bonnets?
The problems i've had so far are as follows:
- broken off some exhaust bolts, though hopefully i should be able to get a stud extractor onto them.
-What to do with the oil feeds from the turbo, but i blocked off the return to the sump, and welded up the pressure line, it will just put more oil through the vacuum pump in the back of the alternator.
-Water cooling lines from the turbo were just feed straight back to return.
- routing of the intake manifolds, they are still waiting on TiG welding up.
-I'm worried about excessive heat around the oil cooler from the exhaust so i've to some heat wrap for the exhaust which will hopefully solve that problem.
-The only other thing i'm worried about at the moment is what happens when i use my gears for braking, as the supercharger will still be turning forcing all the air against the valve prior to the intercooler. I figured that this could both be a good thing helping to slow the vehicle down by loading up the supercharger or a bad thing over pressurising the intake manifold. I'm thinking maybe use of an external wastegate or BOV may solve the problem (i'm open to ideas or comments here).
-I was worried about tuning for a start but after talking to a diesel servicing centre they advised me that no tuning would be needed as with a mechanical fuel pump, it just goes of the engine RPM, how far you have your foot to the floor and available pressure, so everything just sorts itself out (hopefully).
I'm about 4 weeks away from finishing i hope (subject to weather, work etc).
Will put some pix up closer to finishing time
Hope this has been an interesting read, feel free to comment or ask questions if you want to know more or have ideas.
