Buschur Racing's electric power steering for the EVO8-9
Buschur Racing's electric power steering for the EVO8-9
Well after a many-year-delay, I have finally figured out, installed and built kits to install electric power steering on the EVO8-9. I'm glad the original idea and parts didn't pan out as it was extremely complicated, heavy and wouldn't have worked as well.
I was speaking with a friend of mine who races Porsche's and came across the pump I ended up using.
The kit comes complete with the pump, mounts, wiring is set up and labeled and the lines. It will fit with the A/C in place and the stock or Magnus cast intakes, those have both been verified. I do not know if it fits with ANY other combinations, with ABS or anything else, so please don't ask me. As I learn more I will add to the list.
The pump operates any time the key is on the way we send it. If you want to put the pump on a toggle that is easy enough to do. I have it wired this way so that in the case the engine shuts off or is just not running the power steering functions just like if the engine is running.
I have now put about 200 miles on my car with the kit and the steering to me feels like stock, I don't drive many EVO's on the road but if I didn't know it was electric I'd have no idea it was changed. I'm looking forward to auto crossing it actually.
The entire reservoir, pump, lines and belt are all eliminated so the engine bay is a ton cleaner.
Weight loss is about 4 pounds compared to the stock components and the weight is all moved behind the engine with this. You will also gain some horsepower from not driving the power steering pump anymore.
This kit works with ANY ECU and the entire unit is self contained.
*NOTE, after auto crossing with this on the Bad Bish I do not recommend it for a serious autocrosser, it doesn't react fast enough when the wheel is yanked quickly.
The picture below shows the kit installed on the Bad Bish.
New HUGE reduction in price, $800 for the complete kit minus the accessory belt.

people have been trying to do this for a long time and it's nice to see one complete
This is nice! It'll def make the engine bay cleaner!
I see on the website that you will supply the accessory belt.
Do you know what kind of belt you would use ?
Also do you have a belt you would use if there was no ac?

Uhhh, You have one less accessory to spin. That frees up power. A little more load on the alternator isn't going to make it harder to spin.
Physics-Conservation of Energy-Fundamentals of Generators, more electrical load = more mechanical load required to drive said generator of the electrical load.

The electric water pump kit we use to sell gains 37 whp by eliminating the water pump. The electric power steering is about 15 whp on average.
Actually......while your theory, is correct, when it comes to accessories on the engine and the trade off of the electric load vs. belt driven components the trade off isn't even close. Why do you think the OEM builders are taking all that crap off the engines in the first place.

another way to explain it would be yes there is more load on the alternator. but the extra work needed to make that extra 6 amps (or whatevr it draws) is no where near as much load as driving a mechanical belt and pump. so there would be nice gains. and its 4 lbs lighter overall. very nice indeed.
dave, does this pump sense load? I only see a power and ground wire.
