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 …

Mustang hydroboost valve cover clearance

Post  Caindog110 on Sat Jul 28, 2018 9:26 pm

So this is my first post, I am maybe 2/3 the way though my conversion. I am doing an ls1 with mustang hydroboost with 944 master cylinder. I have the 1/2” spacers, engine mounts, and adapter bracket from TPC. I also installed the firewall reinforcement plate for good measure. When I was installing the hydroboost adapter plate I noticed the 944 brake pedal clevis was not inline with the pedal and was binding. I slotted the holes slightly in the adapter plate moving the hydroboost closer to the engine, I’m guessing about 1/8 to 3/16 of an inch. It looks like the brake clevis is now perfectly aligned with the brake pedal but now I have eaten into the hydroboost to valve cover clearance. One of the valve cover bolts is uncomfortably close to the adapter bracket of the hydroboost. Does anyone know about how much the engine moves under load. I could probably file the master cylinder down a bit but I’m not sure what a good clearance target is. I would rather not run solid bushings if I have a choice.

They are all really close like that. Engine barely moves, and not enough to hit.
