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 …

I'll start checking mine regularly too. I have the same RE parts with Koni coilover helpers and torsion bars still in place. My trans mount is a factory one filled with urethane. Been through some CVs too but I think my problem was the VSS wheel, not trans movement.

Anyway... hope you have it all sorted for this weekend. Good luck!

That’s pretty much what I said except for the “due to the bolt not being tight” part. It was due to a separation in the material. Defects in workmanship (lose bolts) fail sooner than later and won’t go years before failure. Either way the bolt served you well under the circumstances.

900 lb springs, IIRC, is approaching no suspension under compression so there is a lot of force on that mount. Add a little wiggle room (literally) from the worn prothane bushings in the transaxle mount and the failure becomes explainable. IMO, worn bushings in your application (racecar) led to bolt failure which led to cv failure.

I like the idea of adding a track bar/trans brace with the 944 design. I usually went with solid engine and transmission mounts in race only cars to eliminate worn bushings.

Did you ever notice that racecar spelled backwards is racecar!  Very Happy

I'm currently using the stock bolts and stock tranny mount. Thought you couldn't use those bolts unless you had heim joints on the shocks? I have the Bilstein rubber mounts...

The bolts work fine with my Ledas, but Bilsteins can be a problem. From Karls website:

NOTE: This adapter is for use with shocks which have a ½” ID spherical bearing on the end with a width no greater than .5”. If the spherical bearing bore is greater than .5” wide, as is used on some Bilstein and other shocks, a longer adapter bolt must be used. Contact Racer’s Edge before installation if you have any questions concerning this issue.

Interesting. Looks like I should call Karl and ask about it. Although it really doesn't matter since the season ended before I could get my car out there...

With the Bilstein Escort Cup you don't need the RE mounts. I'd like to get that setup to replace my Koni stuff so I can go back to the factory bolt and install my tow hooks again.

spent some time at the dyno yesterday with restrictor plates, trying to play around with power output for different racing classes.  See below.

Interesting - where are you putting the restrictor? When I tried putting it between the MAF and the TB, the TB plate hit the restrictor.

On the front of the throttle body, no issues with the throttle plate.
