Joe's FP Reducer kit works!!!!

[tekkie]

jroof I dont have my kit yet but I am sure you will not have any problems, I dont know much about turbos either but I have managed to install my boost gauge, turbo timer and boost controller by myself. I am sure that someone will post detailed instructions with pics if Joe did not include them already. I cant wait to get mine

while we are on that topic did you ship mine yet Joe?

 

[yashooa]

Ewwww

Sounds incredibly promising to me as well. My only concern is the install. I know nothing about turbos and close to that about motors, aside from general functions, despite the fact that I'm mechanically inclined. So, are the directions explicit enough for me to locate all the correct hoses and cut the right ones?

"Eplicit" Joe I think he want pics of you doing the install in the buff.
Well better get that ol polaroid out and have Perfywerky come over to play the camera guy.
You have no choice it's all in the name of SPEED.

Exactly. Nothing makes mechanical work easier to follow than tastefull use of man-ass.

Sounds like it's bleeding off some of the extra boost pressure the stock FPR sees to increase the fuel pressure and therefore the amount of fuel? And this is just a mechanical way of lowering the pressure, effectively leaning out the fuel. Sort of like a MBC for the FPR so to speak. Am I close?

Anyway, really glad to hear it works well. I'd suspect it would make a difference on the dyno...anyone care to give it a go?

Just wanted to add another day of driving around & the kit still proves to be working great. Yesterday was around 70 ( still kind of cool ), but the car still feels consistent. You guys will be very happy whit the kit & dont worry about the install, Im a beginner & with the instructions youll be fine. Also use the pics
on this thread to help find the Vacuum line

I didnt want to start a new thread & take up space, so here are some pics of what Im calling the poor mans modification

Just adds some flavor to the wheels I think!!!!

black lugs? What are you doing with your old ones?

Those are the old ones, that's why I called it the "poor mans
modification"......LOL, I just painted them, while I was working
on the FPR kit.....

 

[Newf]

oh LOL

That's great man. Good work. I'm interested in picking it up now. tell me where to send the money and how much,.

You can ather use the add to cart buttons on my site (www.joepmbc.com - go to the mazdaspeed page) to pay vial PayPal or send me a check/money order to me. Email me for my address- kwiktsi@nycap.rr.com Thanks.

Tappin my foot waitin for mine. I hope I get it today, so I can put it on with my Boost Controller. I GOT DRAGS THIS WEEKEND JOE. :mad: j/k thanks again for stickin with us, and helpin with the "budget mods" Ill hit you up about the SRI and heat protection.

What was your name again? I have a stack here to go out today if it isn't already on it's way out.
Joe

 

[kwiktsi]

wow, if a couple more people give this mod the thumbs up I'm in! If the stumble can be defeated the MSP will be nearly perfect. How much stock is there on these kits? Will he ship to Canada? I'm watching this thread like a hawk!

(hand) I am not trying to market this kit as a "stumble eliminator" - that is purely an ECU mapping issue- It is designed to lean the overly rich mixture out to a realistic level and help take the edge off . It will greatly reduce or completely eliminate the stumbles you get under boost from 4500rpm's up, but it my goal wasn't to go after the actual stumble- just the cause of it- too much fuel. The little hesitations you get while out of boost while driving around- like the bucking you get if you accelerate in second and let off the gas are not going to be affected..

I don't mean to sound like a jerk- I just don't want people to get the idea that this is a purely a stumble eliminator or something- because then there will be the one person who's car will still stumble and they will start bitching to everyone that it doesn't work . It does what it is supposed to do- drop the fuel a bit to lean out a pig-rich fuel mixture to a more effecient level while still keeping enough fuel there to be safe. The stumbles not being there or not being as bad anymore are a result of the fuel being reduced ...

You got it. I was going to make a mini-MBC type valve for it, but I found a cource for ball and spring check valves with viton seals available in a range of seat/spring pressures and flow rates- so I tested it with an MBC hooked as a bleeder so I can adjust it to get it close, measured the psi of the seat pressure and ordered an assortment of check valves going up and down from there and found the one that was best suited all around for the application.

Craig Joe, Craig. LOL, Ohhh, to thread Jack here, I installed the MBC and boosted to damn 15 psi.(shocked) I figured out the issue (had ti adjusted WAAAAAYYYYY to tight, Now boosting to 9 psi, Skie to 10 in 3rd and 4th though. ) Thanks Joe. Ill dyno it next weekend.

 

[kwiktsi]

Wait a minute- Didn't I send the FPR kit with your MBC? You got the MBC, but not the kit? They were sent at the same time in two different envelopes. Let me know if you don't get it in the next day or so.

Yeah I gotcha Joe, nobody expects miracles but any improvement in this matter is worth the money you ask. I have emailed you regarding this and your MBC.

Its probably sitting in my mailbox right now. Ill install it for the drags Friday, and make an appointment for next week at the y dyno to check the gains with the mods>

Thanks again Joe.

I am also not trying to say that it doesn't help either .. Just trying to cover my butt .. I replied to your email. Let me know if you have any further questions. Later.

OK, keep me posted. Later.

will this improve fuel economy if it is leaning some of the richness we are experiencing??

 

[kwiktsi]

Turbo cars drink fuel like there's no tomorrow while under boost, but it does lean it out a bit. I don't know if it will be a noticeable reduction or not. I honestly never pay attention or care about wht I am going through for fuel because I know my driving alone isn't very fuel effecient . Hell- driving to FL, my Fiancee got 29-30 mpg and I got 24-26 ...


I do have another unit in the works that will pull some of the fuel while in closed loop also, so that will help with economy some while helping to reduce the low and mid range stumbles.
