Think the Speed may have blown something downlow

[GongShow]

I completely agree, and it seems that the dp is the deal breaker.

I would still like to see the other unknowns.

No more FP worries here, Just order MazdaSPEED3 HPFpump from CPE. Should be in tomorrow,installed by Saturday right before the tunning session.

How's the install on a fuel pump? Can an idiot do it?

[demonspeed]

Yes. And in under 45 minutes, from what I understand.

what about the fuel pump on a stock motor with only a bsd done?

you need to see what its doing honestly, me personally i drop to well under 800 at the moment it was fine up until recently.

Damn, Shon, beat me to the response...

It was pulled for liability reasons. Like any "upgrade" a manufacturer runs the risk of blame. I have had my MS CAI for 43k miles and NEVER had a cell or a problem. I do have the air straightener. IMO, the MS CAI is the best design out there. Besides, SRI's pull in warmer air.

Cobb makes a CAI? hmmm.

Have no idea what this means...The MS CAI is an integrated design that fits perfect and designed for this car.

VERY EASY I hear. Solves fuel pressure issues instantly. If any of you have gotten that high rpm stutter or cut, it's fuel and the cpe pump will fix any issues up to 400 whp.

For anyone with logging ability, check fuel pressure. If at anytime at high rpms, the fuel pressure drops off significantly, you are pushing the fuel delivery limits of the stock CDFP. Log on the coldest days. Fuel flow past 20 gph will result in a cut.

I have a MSCAI as well. But, I wouldn't say it's the BEST design out there. Let's face it, the location of the MAF is a bit to be desired. The addition of the air straightener would solidify the point. However, I am pleased with the gains, sound, and overall appeal of the product.

SRIs have plenty of cold air creeping in that it's a bit of a moot point. Also, with that snail generating so much heat, it's not as critical to scavenge cold air as it would be with an NA motor.

But, I'm glad someone else out there doesn't feel the need to tee off on the MSCAI.

HPF Pump #0085 delivers a smoother power band. I haven't had the car on the dyno yet, still breaking in 900miles of the required 1000 miles. But the data logs don't tell lies its plan to see that the flow/pressure is able to handle engine loads better....

[eddelgado]

FBPEM1 am I right in understanding that you had verified that your pump was operating properly and that it has now changed and is not keeping up the pressure as it was?

Is this due to more fuel demands because you have made changes to the engine or has the pump performance dropped without any other engine modifications?

If you made changes then that is a smaller issue because you may be requiring more fuel. If a pump that was working properly is now not keeping up with the same demand from it then that is a much bigger issue.

It could also be the case of ambient conditions aka "fickle mazda syndrome". In short, the weather changes, or you cycle the key, and the pump takes a dump. Well documented, happened on my car, and the only solution is new pump internals or a complete pump, both of which Protege Garage can provide at an unbeatable price.

Wassup61 that is not reassuring. From what I have read people are basically redesigning the pistons to provide more fuel - the basic pump is the same. Do we know that the problem that has occurred with these "fickle" pumps was due to a problem with the pump's piston? If we do not know that then you can have it happen again at any time even with a rebuilt pump - ie new piston design.

The pump failures are simply based on the demands on the fueling system. Nothing within the pump physically fails, there is just more demand placed on it than it can support. The upgraded piston raises the capability of the pump, and there has yet to be a case where the upgraded pump can't support the level of air entering during the combustion cycle (big turbo guys with maxed MAF sensor voltages don't hit a fueling based cut).

Good information. Has there been reports of people with bone stock cars with failed fuel pumps?

[wassup61]

Yes there have been. 07s and 08s seem to be more affected than 08.5s and 09s.

Pretty sure the TSB says manufactured before Nov 07, forget the VIN though. Check your date on the sticker on the driver side door panel.

[Fa5t]

Oh, so this was a known problem fixed by Mazda?

The failing pumps yes. But after you add enough mods/power even the proper stock internals may not be able to flow efficiently under higher demands.

[Fa5t]

Yeah I plan on staying stock for a bit, but I was planning on when I do mod to have a HPFP or internals done as one of the early mods. And I mean when, stupid newly installed lift is making it hard not to tare into this car.
