    Default Need a new hpfp

    On Monday out of nowhere my car would hit a wall in 3rd gear, boot would cut off and it would stutter. Even in first gear it was doing that.
    When I drove Tuesday, Wednesday car was fine and had no problem hitting full boost.
    So I dropped it off at the dealership today and they called telling me the issue was the hpfp and that I need a new one. Thank god it's under warranty.
    They told me the current one most likely was defective.
    The only mods I have are a cai, bpv,and CBE.. I know anything more then thy I would have to upgrade the hpfp.
    Car only has 23,000km
    Just thought it was strange

    Given the difference in fuelling logic between first and second generation Speed models, you arguably should have already had a HPFP installed.

    Actually you may want to consider upgrading the hpfp even with those simple mods. The gen2 speed 3's it was recommended that you upgrade the hpfp before installing a CAI.

    You are lucky to get a replacement with the CAI installed.

    Upgraded HPFP is recommended but not "needed" unless you are one of the lucky few who's fuel pump goes poopy, but I do understand where everyone is coming from with fueling issues as we all know about the zoom zoom boom boom.

    You have an AP or dash hawk? (you should get something to watch your pressure cuz SFW's comment about the CAI)

    Edgeautosports has deals on the accessport and autotech internals combos if you don't have either already.

    What a great time to see if they will give you free labour on the purchase of a HPFP even though the install is pretty basic, it's cold out. I'd ask if you could bring in your own pump, dunno if it would fly but probably couldn't hurt. I'm surprised they are giving you warranty as well

    Yeah that would be a great idea, everyone is pretty easy going at the dealership.
    Too bad I gotta wait till spring for any more goodies on the car, I guess house repairs are more important lol
    I'm surprised they covered it under warranty, I told the service advisor my mods and if they were the reason and he said not at all.. Lol

    Too bad your dealership is out in Nova Scotia, as they seem to be really understanding about mods and just in general.

    yea my buddies speed about a year after the cai and bov was installed was ok. but once the exhaust was installed the fuel pump was cutting out and giving troubles so he had to get the upgrade.

    Check with Alphamotorsports on TM3 or EdgeAutosport on MSF/their own site.

    Full replacement or internals they should be able to help you.

    You can get internals from:

    http://www.ctsturbo.com/cart/product...it-463-24.html
    http://www.edgeautosport.com/autotec...p-upgrade-kit/

    I bought mine from CTS as they're located in Canada.

    Default Need a new hpfp

    Thanks for the links, I thought a hpfp was $600 +.. Those prices on the links are reasonable!
    Well for now ill get them to replace with a OEM pump and if I run into any issues before spring ill know where to buy.
    It's kinda ridiculous how the hpfp needs to be upgraded to do anything.. You think they woulda changed that on the 2nd gen hahha I'm sure that has been ranted about a number of times!

    Just to clarify, the links I posted are for hpfp internals... not a complete full replacement pump (those cost $600+). Which one you choose is an open debate and entirely up to you to decide

    from what i know is it has a different tune vs the first gen which you can almost put any mod in and have it be ok. im sure someone knows the specifics but i would think it runs pretty close to its max as it is where the first gen may not. but who knows.

    Speeds are not the only performance-oriented cars with fuel pump issues. E92 335s apparently have similar issues once you start making more power than stock.

    My buddy just picked one up and was debating between getting a JB4 or a HPFP...luckily I steered him in the direction of the fuel pump.

    I've already got the plan worked out for when I pick up my Genpu

    RMM > BPV > AP > HPFP > SRI+TIH > DP. Probably the safest possible mod path (except for starting with AP + HPFP, of course).

    In the Gen2 the if the fuel pressure drops below 1600psi then the injector pulse width increases causing the car to over fuel and robs power and thus saves the engine, where the gen1 it would lean out hence the Zoom Zoom Ka Boom.

    Now the variances with manufacturing of the HPFP has actual some Gen2's with just as much as an intake installed cause fuel pressure to drop below 1600psi at WOT and cause power loss. You will never blow an engine in a Gen2 just hit a wall with the HPFP.

    I had a MazdaSpeed CAI installed on my Gen2 and on my logs I would hit 1693psi initially but as speed and rpm increased it would stabilize out at 1740-1750psi at WOT pulls in my logs. Every car is unique and you must be able to monitor fuel pressure but with a catback exhaust your fueling demands might be more than just an intake. Log and post with new HPFP.

    They have a recal on the HPFP's also on the injectors

    As for everyone wondering why he got warranty on the pump, dealer has to prove the pump failed because of mods. Pump is mechanical for the most part and therefor cannot be affected by Anything else.

    As for replacement pumps, spend the money and get the CP-E one. Up front you have to fork over about 1000$. Once you send your old pump back they return 400$ to you. To bring I over the border it's about 80$ in taxes. Just make sure you choose USPS
