Turbo & Supercharger is a total waste of power supercharger will take power from the crank and getting a turbo and SC to work together is super hard and not reliable. You want real good rods, a M47 crank and good pistons. Turbo it and shoot the spray early to eliminate turbo lag. I would even think of running Meth for the nitrous enrichment to eliminate detonation. Also you will need to remove 2 degs timing for every 100hp of spray you shoot.

I'm interested to see if you do this and how long the engine will last. Make 100% sure you run a Hobbs switch with nitrous or you will destroy the motor.

I would like to see someone build a strong motor and use a 2 stage fogger kit on it. You could make 600 hp on the second stage.


Pictures show a DASC with Fogger kit installed. Run the SC and shoot 150 hp off the line and as soon as it hooks up dump a 400 hp second stage of spray.

I have played with Nitrous for over 25 years and if used right it will be a safe power adder.

Best of luck, John Smith

The idea of twin charging is a rare thing to find. So the idea is that the supercharger works well at low rpm and the turbo works well at high rpm, so in theory you get the best of both. The way im going to run it will be compounding boost where when the turbo kicks in it makes lets say 6psi in to the supercharger and the super charger compresses it further to 20psi. Its a lot of AR math and how to control the boost but i like a challenge. Its all going to be run by a haltech ecu and the nitrous is more for cooling effect to the charged air than for its hp gain. This will be the culmination of years of research, trial and error. Hope i shead a little light on the subject, and the only production car to truly twincharge i think was a 1.4 tsi VW. Search twincharge on google and Wikipedia has a write up on it

Default more stuff

Supercharger rebuild kit and some more parts came in. Box is getting full. Aluminum parts finally got sand blasted and power washed. Pistons ordered and the new rods and crank will be off for race ballance and ceramic coatings.

Finished the supercharger rebuild and put on the smaller pulley. All new bearings and got all that pesky Teflon off the rotors.

Like the sound of this, are you going to be running your boost from the turbo through the supercharger won't that cause a restriction and can the super charger handle that? I remember a nissan micra turbo/supercharger that nissan made think they called is a March R around 1988 it was

So I'm hoping it will work like this. When I pull up to the line push in the clutch pedal and put the motor on the to step in line lock. Then the throttle can be pushed down and the rev limiter will hold it at about 1100 to 1800 rpms. As soon as the clutch is released the RPMs in line lock will be released. I may have to play with this to find out how much the RPM's are going to come up between the time the clutch is let up and when it engages. I'm hoping it will hook somewhere around 23 to 2500 rpms. So off the line I will be running on the supercharger boost of about 9 to 11 psi. The pre supercharger nitrous fogger nozzle will have a lower shot somewhere around 75 to 150 shot that will be used for mostly first and second gear. After the turbo begins to build boost that boost will then be forced into the back of the supercharger which will further compounded it. I haven't decided on all my final boost numbers but as an example if 6 pounds of boost go into the supercharger that normally builds 11 pounds of boost it can compound that 6 pounds into 25 or 30 pounds. Then the second kit of nitrous which is the direct port fogger nozzles will be for third and fourth and fifth gear. This will be a fairly big shot maybe 2:50 to 400 but it's mostly there to control intake air temperatures post supercharger so that I don't have predetination in the intake. It will also add power but it's mostly there for safety. Basically I'm going to try to have the computer apply as much boost and nitrous as the car can lay down to the road. I will be using G sensors and a data logger to record and control power. Hopefully I will have an excess of boost in almost every rpm range and gear. Since this is what I do for a living I probably won't be giving out 100% of the specs and parts I use unless I decide to sell the car years down the road. I'm using a lot of v8 drag racing tricks and putting them in my euro rice. If I'm not breaking records or parts, I'm not happy

When i first ran the nitrous i tried to line up the nozzle with the throttle shaft, my hope was to not add any more turbulence. I also bought a obd1 Dinan throttle body and bored my obd2 throttle body to fit the bigger plates. As far as i know they never made a larger obd2 throttle body. Just some of the details I'm trying to add

I'm interested to see how this works out. Please keep the board up to date with anything you are willing to share.

I will. I'll also probably shoot a couple youtube videos of first run, first drive, and first track pass exc.

Found out that the head on the engine I bought is bad, so looking for another. But I got my template for my oil pan baffle made. Now to buy some thicker sheet aluminum and cut out final parts, and weld in.

Man I think you know what you're doing. Please keep posting pics since I'm learning new stuff each post.

That baffle, what does it do? Guide oil to the pickup or something else?

Thanks, John S

Default oil baffle vs. windage tray

On the picture above the factory BMW part on the oil pan is the windage tray. That keeps the crank from slinging oil down into the oil pan in creating air bubbles in the oil. The next step is an oil baffle, which traps the oil around the pickup during hard acceleration or hard cornering. The little doors only let oil flow in around the pickup and then won't let it flow out, or slows the flow.
