I think you guys were doing George's install the same time I was doing mine. Tim included a very detailed full color installation manual with my kit, which I edited for the nuances of the '89GT. I looked at the manual to see the specific instructions Tim had included for the plugs, before I completed my post above. My manual specifically said to insert the plugs from the inside, and clamp them in place with a clamp Tim supplied.

I know George's install had some differences that were necessitated by the location of the oil cooler on his MY car.

Your are correct, we agree on the basics of the design intent.

Thanks all. I'm not going to get a chance to work on the car now until Saturday. The hoses are plugged and clamped, but the hole in the MAF boot is just plugged from the inside per the instructions - I will probably go ahead and use the bolt/washer method to properly secure it. I'll also fabricate a strap for the Intake/MAF boot and bolt that sucker down.

Cheers

Bolt/washer method. Damn good idea!, wish I had thought of that. It is such a good idea, that if I go back in, I will do that modification. Damn good idea, and bullet proof, especially if you use a lock nut, located on the outside of the boot.

Rob Roy

ain't this place great!

Bill Ball

Yep, that's what we did on George's. Those plugs are not going anywhere.

Q is there any way to keep the oem vap system intact and tie the hoses in the new breathing system using some oneway valves, my thinking if if i wanted to go back to stock al i have to do is plug the oem back into the valve cover

Bill Ball

Now, that's a thought... plug the other end of the hoses. Reversal would be a lot easier, since in doing the reversal you must have the boot installed before you can plug the hoses back in. This is a PITA with the intake in place.

However, this requires that the stock fittings will not pop out of the boot or leak under boost. Not sure that is true. In fact, since they are not clamped to the boot, they are not designed to take boost and will probably at least leak.

Bill or anyone for that matter can someone post a pic of the vap routing with there oil seperator installed and also if they have a aftercooler a pic on how they are suppling the liquid to it thks. i want to use my window washer res as supply but havent looked at how i need to plumb it in yet.

Murphy gets paid for his design work. Some folks here did their own design, maybe they will be willing to share their thoughts.

Don’t feel bad if you don’t get any replies for this question. I’ve posted a similar question last year and got very limited response. I’ve built my own crank venting system, however it’s not ideal…. at least not yet. Still have to figure out the correct venting points and hose routing.
Some people are very reluctant when it comes to sharing certain information. They love to take but not to give.

AFAIK no one has a low cost solution for other than street drivng, being under prolonged boost conditions is far different than street.

Murf & Todd found the obvous reason why his setup did not work at The Autobahn. Plan B is in the works. Testing will be early spring at Road America.

Assuming this works (and when Todd is involved, safe to say it will one way or the other) it will be another product offered by the Murf team.

Gee, my oil control system is still working without a external drop or reservior...in fact the 89' I originally designed it for is being upgraded again. 2 years on 10psi as a daily driver by an admitted leadfoot with some extended high speed "testing" has verified it's capability. It currently has a V1-T spinning as fast as possible with no measurable blowby. We are at 4400' elevation, takes a lot out of a supercharger.

I have not mass produced my system, it involves removing the cam covers to install. I will assemble a kit if there is enough desire. (10+ kits)

Gretch

I don't push mine that hard, (generally) although Gretch has seen 10 psi on several occasions. However the oil recovery system Murph sold me works just fine, with no oil loss, and best of all, no oil ingestion.

However, like I said, it is a design I purchased the use rights for, I do not own the intellectual property.

NP those of you that would like to post pic it would be nice, I have my own design and just wanted to compare and maybe impove upon (mine or thiers), thats no differant than us sharing info and mods on our 928's after all the 928 is the design work and intellectual property of porshe isnt it?
