Goopy Performance resurfaced rotor housings,THEY WORK!!!
I have been working with Jon from Goopy Performance on and off for many years. Many times we have different views, but when he comes up with something that works, well I have no choice but to post some of my results and experiences. Jon has perfected a way of resurfacing used rotor housings. I mean this is pretty impressive considering most of us throw away rotor housings that he brings back to life. I will post pics of before and after.
Back in late 2007 Jon came over to me and asked me to try some crappy rotor housings he had resurfaced. I looked at them and said "Jon this will not work" Jon said: "Ito just try them". To give you guys an idea, those housings were grooved pretty bad by the outer edges of the housing and the trailing plug area were full of vertical grooves .(a common problem) and pretty much garbage. I Put 1 engine together using his used resurfaced housings with New oem 2mm apex seals. After 200 miles of driving I gave the engine a compression test @ 195 degrees of coolant temp. The engine gave me 125-128 psi with a conventional compression tester. Since then I have put a few engines together with Jon's resurfacing. The better the housings are to start with, the better the resutls. The FIRST THING I NOTICE IS THE REALLY GOOD FLAT SURFACE after the resurface. On my last engine I did a compression test and pulled 131-132psi using his 2mm apex seals. I was stunned to say the least. I'm here applauding Jon from Goopy performance not for perfecting this resurfacing on other wise rotor housings we would have thrown in the garbage, but for his continued hard work to improve all kinds of minor and great details this engine has to offer. for info. you could pm me.. I'm a skeptic that turned into a believer. congrats Jon. pics of before. ![]() ![]() ![]() AFTER ![]() ![]() ![]() enjoy Last edited by TitaniumTT; 12-19-2010 at 07:40 AM.

They look great
![]() Are they running on the SS liner after removing those very deep marks? do you have any pictures of a housing that has run say 20,000 miles on OEM seals & high power after this process has been done. What is the cost.

Spectacular. I always wondered if this could be done, and hoped someone would figure out how someday. LOVE IT!

I can't really tell on the before pics, but was there any flaking of the
surfaces on the edges of the housings or were they just scratched and scored?

Is that a coating on there, or is that just a really clean housing?!

those particular rotor housings had no flaking to begin with, just grooves. grooves were eliminated and a flat surface was achieved.

So this process will not get rid of the corner seal wear from the three piece seals? I have a few housings that have this wear. More or less the chrome is flake right off..
