Rally2003's Build Thread

Let my buddy co-drive the MSP with me today and blew another PS pump. I don't think it likes spinning and pushing fluid while the motor is around 6,000RPM's. 3 pump this year that I've blown the sensor out and shot fluid out of. Appearently the PS pump is a bigger problem to me than the FS motor. Ran my best time with 3 other people in the car. Was a blast, but didn't get to run my 5th run because of the PS pump failure.

I wonder if your intercooler piping is shifting and hitting the sensor? IDK that's just crazy
 
The 1st one was from autozone. The 2nd was an OEM off of Evans P5, and the 3rd was a OEM off a 626. I don't knowif I should try a different PS cooler or go electric.

I moved the piping since that last time and it is no where near it any more. The pressure within the pmp is blowing out through the path of least resistance. In this case it is the little sensor in the front of the pump. It is only about a 1/8 or less thick.
 
Do you have stiffer motor mounts, Corey? I can't remember.

Yeah its tiny. So you redo all those couplers underneath then too? :)
 
Nope, not yet. I just made the bend before the PS pump so it was no where near it.
 
Thinking about doing a electric pump conversion from a 93 MR2. It would get rid on the secondary belt all together and would have less stress on the motor and I wouldn't have to worry about it over heating because of the shaft spin.
 
let me know how much that costs corey. i have a leaky power steering pump as well
 
Where is it leaking from? Could be a different situation.
 
Not cheaper by any means. You can get a decent pump at the jy for $30-$40 or a new new pump for around $250. A new elctric pump is anywhere from $500-$900 and that is without fittings and hoses.
 
lol
On a sad note the cf fender somehow warped when I applied a coat to the back of the fender and top edge. I don't know if the heat from the resin when it dried shocked it and the combination of the way it was sitting on the table. I don't know and a little frusterated. This cold weather isn't helping the drying process at all and I think I'm going to have to wait until spring to further the project and not was any money. It would be different if I had a house with a garage and consistant temperature to work in. None of this 70 one day and 50 the next day crap. Oh well, in a couple weeks the all the panels will be unbolted and I'll start making molds.
Still undecided to go with A) the easy way with a ps cooler w/ new pulley pump or B) an electric pump that would free up the motor a little, not have to worry about a over heating issue, and clean up the engine bay a little bit. Decisions, decisions hmmmmm... More to come over the off season.
 
Could there be a restriction in the system? Just spit ballin'. An electric pump seems like an expensive science project to me. I mean if there is an issue and then the electric pump takes a very expensive s*** on you. There has to be a problem in the system some where. You had no problems before the engine swap, right? Now you are on your 3rd, or 4th pump.
 
This will be my 4th pump going in. I really didn't have a problem until I started racing with the FMIC so it probably is the FMIC blocking the air flow for the crappy stock ps cooler pipe, either that or the ps pump just can't handle the constant spinning at high rpm's and the pressure of turning back and forth quickly. Right now I'm just looking into other options. Either way I'm spending money. Another ps pump and cooler is going to run around $300. I just don't want that not to work out and have to buy another pump and or thengo the electric pump route.
 
Less pump... More carbon fiber!!!

Haha but seriously, when working with carbon fiber you really should have a temperature controlled environment...
 
^Agreed and that is why I'm waiting until next spring. Falls in Ohio can be really nice or suck as and mother nature is on her period right now and can't decide between the two.
 
I would try a cheap aftermarket oil/ps cooler. Just be sure it is placed for max air flow or make some sort of ducting to get air to it. Another idea could just be ducting air for the existing cooler.
