goopy rotor housings compression test !!
 

hello !!! well, I have been meaning to post some results. here they are. stock 3rd gen motor,rebuilt with goopy rotor housings. both housings sent over came from motors with broken apex seals. not re useable. after the service, here you go. nice even numbers front and rear at low cranking speed.enjoy !!

note: this isn't my first set of housings from them either. used quite a few sets with similar results.

Nice

I have hear great things about goopy's products.

He built my 20b using all of his components and he reinforced and doweled the motor. I cant wait to have it up and running.

About 120psi, very nice. I would be interested to see what they do after 10k miles though. Is that a totally fresh engine not started or does it have some mileage on it?

TitaniumTT.. I will be doing a mileage writeup on their seals once my build is up and running.

Looking forward to seeing the results

yes,I agree . however, I have used quite a few of these housings in motor builds in the last couple years.no issues. similar compression results.cant see anything that can really go wrong. just removing a little material. plenty of apex height .after all, whens the last time we saw an apex seal wear down as to not make contact with the housing ? they break before then (oem ones at least).in any event, I have been quite happy with the housing service. saved several of my core housings.

fresh engine . basically it was a previous mazda reman with unknown mileage. had a blown apex seal. everything else was in nice shape.

cant wait to see if goopy houses are up there in the numbers after some K miles and a few years :)

hmm, maybe i wont make a clock out of those old FD housings after all ;)

Rumor has it they are still holding solid compression after 5,000 miles :biggthumpup:

Looks good, how's the pricing on these compared to new OEM housings?

^ Hey, newblet... Did you bother reading that first post in the link I put up? Or did you just say "looks good" and move on? lol

(Hint: That very first post lists current price :rofl:)

Essentially they use a high speed buffer wheel to remove defects, seems like this could be done by other machine shops.
