RotaryXperiment · 01-25-2011, 04:05 PM

thanx ito.i appreciate it, goopy did a great job.

wow... nice results!

depending on how bad the inside of my engine looks... youll be getting my housings.

very impressive work ... and for a price that a loser like me can afford.

i doubt if there is any one reason for why it's taken so long. maybe it's technology. maybe it's changes in attitudes. hell, maybe it hasn't been 20 years - i mean, if Ito got a set to test 3 years ago, then there had to be a period of time where this went from an idea to a part-to-be-tested. either way, it's a long-awaited, welcome option for many of us, and hopefully a stepping stone to even better innovations for this engine that we love so much.

I would say things like this are starting to appear because
-Mazda prices are insane
-they are probable stopping production or already have and there is limited stock.

What needs to be done is recoating/refinishing. All my engines (I have at least 12 housings last time I counted. I thought I had 6 until I move a few boxes. Man 20 years makes stock piling!) have the dreaded corner seal triangle wear or have apex damage. Makes them useless with todays current offerings.

I'm going to drive down to Goopy Performance after my DGRR trip

well, i figured there wasn't a point in starting a NEW thread just to say the same thing, so ...

i met with Jonathan (Goopy) last Friday and brought him a pair of REW housings that have seen better days. i probably could have used them as they were, but i figured i'd have him resurface them so i could see it all for myself. i need them for a build right now and figured with resurfacing, they could give me a little more time before the engine has to come apart again. the rear housing was a little more beat up than the front, but he checked them out and told me he could get them done by Tuesday. i got a call (registered at around 0900) from him Tuesday morning saying they were complete and i could pick them up.

bottomline ... they came out awesome! they were worth every penny and i would recommend him to anyone in the rotary world. we talked for a bit and i can tell this guys knows his shit! not only that, but he showed me a few ideas that he came up with for all sorts of problems that come about - real, simple, and effective solutions that blew my mind with their simplicity and ingenuity. this guy oozes passion for rotaries and he's friendly (this is coming from a guy that doesn't have many friends and is not too friendly

).

anyway, long-story, short ... Goopy Performance is truly a breath of fresh air and i will gladly go back in the future whenever needs above my skill-level arise.

by the way, i'll try to post some photos of the housings before and after. i will also try to see if i can get some compression numbers when it's running, too. i plan to make a thread for this particular engine build when i get the time, so i may not post them here, but rather maybe a link.

glad it worked out for u. jon does have a passion for this engine we all have come to respect. I'll be releasing some information soon that will benefit everybody.

Work w/ Jon is nothing short of a great experience. I recommend him. Thanks agian Jon.

I just dynoed my nephews turbo II using Goopy's refinishing job. this is a series 4 engine. 8.5 to comp. on rotors. Rx7 made 400rwhp@ 15lbs of boost. goal is 22 psi of boost but the car would not hold boost. leakin boost all over. engine still pulls 14.9 inches of vacuum. this car is an underdog to say the least and still made respectable power for 15lbs. we will fix the boost leak and go back to the dyno.

Judge Ito · 04-04-2011, 06:46 PM

I just did a 12A bridgeport for a daily driven Mazda B2200 pickup. using Goopy's refinished rotor housings with apex seals. I wanted to do a compression test as close to real numbers as possible. I did not lube the side housings with oil and I did not lube the rotor housings with oil. basically a dry build and dry test. I did not want the lube oil to add to compression numbers. engine made 125psi equally on both front and rear rotor. enjoy the pics..

RotaryXperiment · 04-05-2011, 08:26 AM

great stuff ito!

Judge Ito · 04-05-2011, 02:36 PM

engine fired up with half a crank. i'll have a video up soon.. brap,brap,brap.. sounds pretty healthy this 12A..

Jwteknix · 04-05-2011, 03:17 PM

sweet ride

Judge Ito · 04-06-2011, 06:55 AM
