motor goes BOOM **UPDATED PICS 4/12/13**

[Huehuecoyotl]

I am unclear, why cant DW redesign the tolerances so it can be done with 1 o ring? Its great you know how to make it work, and your results are proven. Not doubting that. However, No engineer ever designs like that.there isnt one other part on any car or plumbing system I work on(Have a 17,000 gallon koi pond) that calls for double up on o rings...

I see the dynos, and I see that the solution works, I just want it better, not that its broken, but thats how I am, and why I work as a systems analyst type when I am not wearing the forum hat too. I want more power but am okay waiting till I NEED to replace my pump, not sure I am there yet, but I can see how its in my future. I've spoken with the owner of Deatchwerks, really cool guy-is he aware of a potential update to theur design to 'better fit' our cars? or is the plan to stay with the double o ring setup? You sure about tracking it in triple digit weather and all?

Do I wish that the pumps fit better and didn't require cutting things and drilling holes and using zip ties and didn't require adding another O ring and came with instructions? Of course I do, but I am definitely confident enough in it to track it in triple digit weather and all. You should be checking your gauges on each straight away, and your AFR will tell you if something is wrong with the pump. My best guess as to what caused Frs300's car to blow up is something being wrong with the fuel system install, although I haven't heard if he had the dealer flash the car or if he flashed the Full Blown basemap himself.

Did anyone actually verify the map on the ECU? If he was running the larger injectors w/ an OEM base map he would be running pretty damned rich once the ecu drops out of closed loop and tossing quite a bit of black smoke.

Thats great feedback, and thank you

I just cant say that despite your reassurance, and in light of the potential that leanness, and that could be a pump issue in a slim chance, that this makes me COMFY

Comfort is different than a dyno, or saying it has worked for years. I get proven, I do really.
I just cant take that risk with my motor, or my life at the speeds I go. Two neoprene o-rings and nylon zip tie in my fuel supply setup? really? track it like that? Let me think on this a bit more...

If there is any doubt in the back of my mind, or in my heart, it comes out on the track, there is no hiding it for me. So if I dont feel 100% on something, I simple dont come on line and endorse it. I dont sell this stuff, I buy it with hard earned money, and I'm not ready to test the Fuel pump at its current tech state, so thats why its not on my car. I am trying to avoid the boom and I too am playing with fire.

I cant acquit the part, its still a possible suspect in my boom investigation.

The thing I would be more worried about would be that it would not be pulling any timing for the added boost and would not be increasing fueling for the added air going across the MAF sensor.

That would be a difference between me and you. I have gone out to races with brake pads that I hope last or tires that I hope don't cord in the first half of the race. Sometimes I win, and sometimes I lose. I buy brake pads and tires with my hard earned money, and I want to get the most I can out of each of them, and it bites you sometimes. Nothing is ever going to be 100%.

By the way, I just got done drooling at that e30 you got in your sigline, as an e36 owner, man that thing is suhweeet

Thanks man. It was a 3 year process of starting with an $800 325is with a blown transmission and going through the NASA HPDE program to racing it 6 - 7 weekends a year. It was well worth the time and money invested.

Everything that's aftermarket for this car is a complete science experiment.

Off topic: why did you vent the steering fluid reservoir on your e30?

True to some extent, this is why we test prove, redesign, and back to test

I am fine taking risks, but highly calculated risks only, this is why we do regression analysis, diabolical testing and double check each test result, each log, and be as careful as we can to plan for stuff to fail.

This thread pretty much made me reconsider my gauge choices, and think I need to order the AEM failsafe and that prime motoring dash single pod.

Haha. I like to resuse my OEM reservoirs. I ditched the power steering and plugged the rack so that reservoir and breather are for the transmission. Some E30 transmissions like to puke out quarts of transmission fluid from the breather cap when doing high g cornering, so we clamp a hose on and run it up into the engine compartment. I am also resuing the washer fluid reservoir as my coolant overflow bottle.

I have the AEM failsafe and prime motoring dash single pod and it came out really nice.

if you simply swap injectors & pump and leave the ecu map the same your injector cycles on closed loop will cycle for the same length of time as the stock injectors. So if you went from 240cc to 480cc you would ideally get 2x as much fuel at the same MAF reading as previous.

There isn't any confusion as to whether or not he had the basemap loaded. He was on the Fullblown basemap.
