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 …

Lighten clutch pedal feel?

Post  docwyte on Wed Oct 05, 2011 9:31 am

Is there anyway to lighten up the clutch pedal feel? Mine is pretty heavy, Spec stage 2 clutch and lightweight flywheel.

It's not an issue on the track, but very noticeable in street driving...

I removed the assist spring on your setup when I built it. You could put one back in and see if that makes it feel different.

everyone with a conversion should have it spare

I also have a stage 2 spec clutch that's a bit of a beast in daily driving and that I'd love to know if it has that assist spring - where is the assist spring supposed to be, is it visbile from underneath?

To think that the Spec guy was trying to sell me a stage 4 clutch! He kept telling me how it'd hold 700 ft lbs of torque and ignoring me when I told him I would be making nowhere near that...

Does the assist spring help push the clutch pedal down, or only help it pop up? Cause it has no problem popping up on its own, that's for sure!

No rush, when you get a chance to lay your hands on them I'd appreciate getting them. Thanks!

Doc,

FWIW, I have a dim recollection of having to remove the spring after the conversion because the pedal would go down fine, but would not return.

If you loosen the spring enough, the pedal will not stick to the floor... I had the same problem and I though I had air in the hydraulic bearing. It was just that damn spring. I loosened it a little and it fixed the problem.

Do you have the little return spring on? Those buggers ae under a lot of tension! I had to have that on my brake pedal and clutch pedal. Brakes lights will stay on without it on mine.

Is that the spring on the brake pedal? Ya, I kept that one. I remember how fun it was trying to get it back on.

Clutch pedal

Post  fliermike45 on Sat Oct 08, 2011 6:21 pm

Remember to adjust the clutch master cylinder pushrod if you have used a firewall stifening plate. My pedal (minus spring) had too much free play until I lengthened the push rod. It is now level with the brake pedal at rest.

Sloan's book advises to remove the spring, what are the advantages or disadvantages?

I have installed a HTOB and have not driven the car yet, but it feels fairly heavy to operate the stock LS1 clutch. My MGB V6 has an HTOB and I soon got used to the heavier clutch pedal.

My best guess is that at the time of putting the manual together, he was under the impression that the spring pulled the pedal back to rest position. Im not too sure why they are being removed.

The spring acts as a booster. With the wilwood clutch master, the increase in volume makes for a increase in pedal effort. So, the spring helps with this.

If you find that the stock spring is less than helpful, you can increase the assist by installing a larger spring. You can find these springs at mcmastercarr at varying spring rates.

Refitting spring

Post  fliermike45 on Sun Oct 09, 2011 3:29 pm

Put my clutch assist spring back today.......tip, compress it in a vice and use two or three heavy duty tie wraps around the coils to hold it compressed. Impossibe to compress in place, I have the tool rash! Easy access with the relay/fuse panel removed.

Spring picture

Post  fliermike45 on Sun Oct 09, 2011 6:43 pm

Here is the spring installation viewed from the top after moving the relay panel.

Items on the clutch pedal arm (from top of picture): Nylon bushing, shaft eye, washer, circlip. At the far end of the spring is a nylon cap with two ears that rides on indentations in the body.


I assume that one can adjust the pre-load on the spring by turning the nut.......can anyone give some feedback on adjusting the spring tension.

Clutch spring

Post  fliermike45 on Sun Oct 09, 2011 7:14 pm

Thanks for the info, the figures quoted are for stock 944 clutches, any suggested settings for a stock LS1 clutch and HTOB?

Sorry I can't experiment yet as I have no exhaust and the car is still up on axle stands.
