More bench testing today, the pump performed as expected. I will be posting pics later this week.

If anyone is having an issue with their pump please contact myself or Mazsport a.s.a.p. We have an extremely high success rate with this pump, if there is an issue I would like to know about it.


Thanks, Scott

what do you mean "as expected"?

did you test it in a car? ran it in boost etc etc?

Scott, I still want to know the specs on the pump since you're claiming that it's performing up to spec.

It appears that you're saying that there is nothing wrong with the pump and that the pump is functional even though it doesn't work in the vehicle. I suppose I can try to offload on someone else on the forum who's willing to take the risk and try it out, if that is where you're heading with this.

^ the new owner keeps telling me that it failed

and Scott keeps telling me that it's working fine

idk what to believe

Since this is going no where fast. I wanted to illustrate how serious this issue is.

Within one month of having the fuel pump installed, Scott tuned my RX-8.

After the first 2-3 pulls, the car starting going LEAN. He had to stop the tuning session because of it. Tuning ran $250/hr.

so lesson learned: don't buy this "upgrade"

Here's the kicker. When Scott told me it was a clogged filter, I was confused since my OEM pump had no issue for YEARS.

I had asked him if the tank needed to be cleaned out if it was dirty enough to clog the filter within a month time frame. He said we might need to do that if it clogged again. At the time, I had never seen how the pump was situated. Little did I know that when you install the fuel pump, you see the inside of the tank very easily. So if it was that dirty, he would have noticed something. I premixed with the same oils after getting the new pump as I used with the OEM. So as I said before, if premix clogs the mazsport pump, then the mazsport pump cannot handle 1 month of premix that the OEM pump handled for 2 years. I don't believe this is the cause of the pump malfunction however.

why were you paying $250 an hour to tune your car?! was this Pre-AP?

this why you went NA? sick of all this bullshit?

what do YOU believe is the cause? overheating?

The situation with the pump and the dyno charts listed above was when i first went turbo. The int-x was the best fuel management we had at the time. I wanted an upgraded fuel pump to prevent exactly the situation I ended up having - a malfunctioning fuel pump that can't deliver the required fuel!

I'm actually NA right now because I literally spent over $7,000 diagnosing and then repairing my car. This is a completely different situation that occurred after Scott street tuned my car (because his coils made the vehicle run lean). I had massive detonation on the drive home from his shop not even 30 minutes from leaving his shop. I tried speaking to Scott about resolving this issue between us, but he decided to not talk to me. This is why we're going to court on the 25th this month. I had wanted to avoid this route, but he has NO desire to make anything right.

I have considered selling my RX-8 because of my experiences with Mazsport. I haven't even gotten started mentioning the issues I've had yet.

mysql

My lawyer advised that I not to say anything about the case online, but I'm tired of not saying anything and what I'm saying here is nothing that I don't plan to say in court next week anyway.

I don't have anything to hide.


I also think Scott has been delaying the diagnosis of the fuel pump till he sees what happens in court.

If he isn't going to do anything and just ramble on about how the pump is perfect, mail it back to me instead of playing games.

Update!

I have been testing and testing and testing Jason's pump here guys, that's all there is to it. What Jason and I have to discuss next week is not effecting my testing procedure whatsoever, frankly I am insulted by the insinuation it does.

Our success rate is EXTREMELY HIGH with this fuel pump! Do things fail? Yes. If a man made it, it may fail. A Rolex, the Space shuttle, a clutch pedal, whatever.

I want to make sure that the results I report are absolutely correct. We are not the shop that would just connect the the pump to power and report there is nothing wrong here. Again, this is a VERY successful product, if one fails I want to know why. I will start a new thread with photo's of and the results very soon, at this time Jason's pump is providing consistent pressure during sustained hours of testing.

I appreciate your patience as we continue our testing, Scott

lol.

Not that I don't find all of this endlessly entertaining, but maybe we should keep the topic of this thread focused on the questionable fuel pump? Just a thought.

Scott, it might behoove you to supply the actual testing procedure being used to test the pump in question, along with what results of those tests you would consider acceptable/normal for a properly functioning pump. If you accept that swapping from this pump back to the OE resolved all problems Jason was experiencing without any other modifications, then there almost certainly is something wrong with it. If the testing procedure you're using now is similar to the production testing done on the unit, and you still see nothing wrong... well, I'll let you draw your own conclusion there.

mysql

I've asked for the pump specs twice now.

MazsportScott

Rest assured Gentleman, all this will be documented very soon.

I am sorry that I find Mazsport Products to be top of the line. Maybe there is a probelm with your Fuel Pump and Scott has been doing tests after test to found the problem. Mysql Claims that many other Mazsport fuel pump owners are having the same problems. Why hasn't Mazsport heard of this until now? If i owned the Mazsport Fuel pump and was having any problems i would have called Mazsport. No one forced you to buy Mazsport Products. I wouldn't say i am a fan boy considering i am not a boy just a fan of Mazsport. Mysql you state you have been to 3 different shops, why not bring the car to Mazsport? What is your reason for bringing Scott to court, the fuel pump or your blown engine....?

/\ as much as i enjoy disagreeing with you - you do put put a strong case here ....

mysql

I appreciate it Brettus.

If I had my way, the mazsport pump would have worked and I wouldn't have had to spend several hundred dollars more to replace it. I tried to buy the best upgrades possible for my car. Look at my picture thread. This is not a cheaply hobbled together vehicle.

I have no desire to have any issues. I don't know why some people are bashing me like I deserved this.

I eagerly await invasion08's response to my last post.

Sometimes it really takes a lot of time to find the true cause.

like my car, it refuse to start, but it happened so random that its not even funny ~ and it embarrassed me like crazy,

especially the time @ gas station ... right after I left the dealership, 1 minute drive, stop for gas, engine off, no more, wont come back on ! they have to tow my car back to dealership, and when they try to put my car down. the car work ! finally they found a row of pins misalign in the PCM connector (!!) no one expect that to happen, I never even touch the PCM.

I am not picking sides, Scott is a good man and he knows his stuff. I also believe mysql knows his stuff. Blah, Nertual.

mysql

^ Exactly. It can take a lot of time. But if the issue isn't happening at the current time, it is much more difficult to pin point.

It was $267.50 for the one hour of dyno tuning (See the chart https://www.rx8club.com/showpost.php...&postcount=273 ). And we only had 2 runs before the vehicle started to go lean because of this pump. There was no refund or second dyno run.

After that dyno session, he charged me $100 to replace the fuel pump filter. As we already know that didn't fix the problem. For what he charged me for the filter, I can almost buy a complete OEM fuel pump! He then charged me to "street tune" the car after he replaced the filter, to see if the car acted up after the replacement.

There's no discounts on this stuff.

I don't mind paying for work if it's good work and if it resolves issues. What I'm getting at is that I'm paying for hardware that is supposed to be tested and functional, and when it doesn't, I'm also paying for him to figure out why his hardware doesn't work.
