HOW TO DO AN ADVANCED SEARCH.

Mon Jul 08, 2013 3:56 pm by Admin


For the benefit of 944Hybrids users there are two search functions available for you to use.
The purpose of this sticky is to explain the "Advanced Search" function because it is much more powerful and is the best choice when researching information.

When you log on to the site a list of options is shown in a line at the top of the page. One option is labelled "Search", use this option (NOT the search box lower down on the right).

After you click on the upper search option, a drop down box appears. At the bottom of this box is a radio button marked "Advanced …

On a non ABS car it screws right into the master. But with ABS I don't know. That might be it you're looking at. If so, removing it will send more pressure to the rear.

What do y'all think, happy plugs? They have 2 track seasons of use.

Having some issues with my Boxster ABS pump. The pump is continually cycling on/off. My shop seems to think it's because the pump I have is a CAN-BUS pump. I got a pump ending in "00" with the two row plug, isn't that the right one?

Do I have it wired wrong? How/what do I do to solve this?

I noticed that the engine was sitting lower than usual and the oil pan making contact with the crossmember. On further inspection, I see that the bolt and nut fixing the driver side engine mount to the crossmember has broken off.

The oil pan appears to be squished in a couple of spots and the driver side header is dented as well. The oil line has clearly made contact too.

While I'm not happy about the problem, I sure am glad to have noticed this at home. Otherwise I'd have been headed for a pretty nasty failure at the track this weekend.

I haven't broken any of the motor mount bolts, but I have destroyed two sets of the mounts themselves.

I can always tell because my steering becomes sticky and won't self center because the oil pan is sitting on the steering rack...

Mine appears to land on the mounting tabs, not the rack itself. No affect on steering, no symptoms at all actually. I'm just lucky to have noticed.

I don't know yet if the mount itself is broken.

Yep, bolt snapped. The mount itself seems fine.

Might have over-torqued these guys a bit. 57 lb-ft is recommended here for 'em.

Eric is giving me a deal on a new set. Great service! Thanks!

New mounts are in. Thanks Eric!

That's also a new starter motor as the old solenoid was going bad. I'm now going to play around with power steering. The Chevy pump is mounted and I'll try to get the original power rack in tomorrow.

POWER STEERING! Oh thank the Lord, power steering!

[You must be registered and logged in to see this image.]

I just did a few laps around my neighborhood through all of the traffic circles. It works! And what an incredible difference it makes in turning the race car around in the driveway. Next will be taking it out on the track and seeing if the pump can keep up with the rack and if the cooler can keep up with the temps.

It appears to be the same Weltmiester setup I'm installing.

Today I took the car out for the first time with the original power steering rack and the LS1 pump. The steering feel is consistent but very light, too light in my opinion. And the fluid heated up to 220 F in just a few quick laps. Dang!

Guess I'm spending the $$ for the Turn One pump.

My steering is also quite light, I am thinking of installing a Heidts PS-101.


Adjustable Power Steering Valve -Heidts
Item # PS-101

Power Steering Valve

Tune your power steering with this Adjustable Power Steering Valve. It allows you to set or "tune" the feel of your power steering with the turn of a knob.
The high pressure steering fluid goes thru the lower high pressure passage to the rack and back thru the upper low pressure line to the reservoir. As the knob is turned counter-clockwise, the needle valve is raised up which allows the high pressure fluid to bleed off into the return line, which reduces pressure to the rack and pinion to tighten the feel of the steering.

You can go from full power to almost full manual with just the turn of the knob!

Rich,

What type of cooler are you running and how is it ducted?

220 may not be that bad, just keep it below 275 [You must be registered and logged in to see this link.]

You could also try [You must be registered and logged in to see this link.] to improve feel.

I'm already using that exact "flow control" fitting. That adjustable one is an interesting idea. My cooler is a simple tube and fin deal strapped underneath of the bumper cover. I could certainly do more but if 5 laps at 7/10ths heats up the fluid at all the problem is with the pump.

Another route I'm researching is an electric pump. I have a mk2 MR2 pump and it's huge. I read that the mk3 pump is smaller with an integrated reservoir and VSS input to vary assist by speed.

My cooler is very similar to yours and with the Turn 1 pump I have no issues with the PS...

Pormgb, are you using the Turn One pump?

Lemming, are you doing that "flow control" fitting and a cooler for just the hydroboost?

Docwyte, is your steering lighter than it was with the Porsche motor and ps pump?

Thanks Guys, appreciate the thoughts.

Yep, it is. I don't have any kind of restrictor in it tho, so I may eventually look into that.

Odd thought, but have you guys considered looking into the electric power assist units like are found on the Prius and I believe some other hybrid cars?  I have read they are reasonably light, and ultimately allow for the assist level to be varied through software based on a number of inputs.

The Prius too? I've been looking at the mk3 MR2 (MR-S) compact electric pump with a VSS input to vary assist by speed. Even the new 911 is using an electric pump. Interesting idea.

No, but I get some strange sounds from my stock pump and my steering feels too light. At low RPMs, my Hydroboost also pulses so I think I need to upgrade.

I do have a Heidts PS-101, this will allow me to dial in my steering feel.

I have done allot of reading but I can't seem to find the correct setup for a 944 rack with Ford Hydroboost. Is the stock LS1 pump with out modifications sufficient with 944 rack and Hydroboost? are restrictors required?
