Gentlemen,
I should have put this post up a year and a half ago after getting these modifications done. Guyett Performance in Fresno, California has developed one of the best air-oil separators available for the Ford GT, but they did not have an application that would work with a Heffner Twin Turbo. There is such limited space available, especially on cars like mine that have remote Penske shock absorber reservoirs mounted behind the rear strut towers. Evan Guyett painstakingly designed twin air-oil separators for this application using my car as the prototype. With all of the engineering work done I am happy to allow other members to take advantage of all of his hard work (and my $). Purchasing a copy of my system would be a lot cheaper for you than it was for me as I paid for all of the initial design work. Quite a bit of oil coats the inter-cooler over time making it less efficient. How much less efficient I don't know but these air-oil separators eliminate almost all of it. They look really trick too. The two black irregular shaped boxes mounted inside my rear strut tower braces are the air-oil separators in the photos below.
A second item that Evan Guyett has developed for me is a machined billet aluminum bracket that mounts on the air box atop the inter-cooler. The stock bracket is a flimsy L-shaped sheet-metal piece and it flexes when you push on the throttle. Plus, it's unsightly. This new billet aluminum piece does not flex at all giving more precise throttle control. But even more important, it looks great.
During the upcoming Rally in Northern California I encourage all Heffner TT owners to look at my car with the clam-shell up to check these Guyett Performance items out. If you have questions that I can't answer I'm sure that Evan Guyett would be happy to answer your questions. He is located in Fresno California and his phone number is 559-349-3570.
I have no financial stake in any of this other than having spent a lot of money to develop some cool parts that others may want to take advantage of. Cheers.
