I'll put my car on a dyno sometime soon, and see what my fuel delivery looks like up top. Can wiring be upgraded from outside the tank and out? Or would it have to be all the way down and into the fuel tank to the pump?

Electrically it's a matter of degrees.
If you beef up 80% of the length of the wire it will be an 80% improvement (in rough principle, not having defined what's "beef up".) For instance, 6 feet of wire at 0.1Ω/ft is 0.6Ω. If you double up 5 feet of that, it's 5' at 0.05Ω/ft + 1' at 0.1Ω/ft = 0.35 Ω total. If you run 5 amps through the first example you lose 3 V. If you run 5 amps through the second example you only lose 1.75 V. If you doubled up the entire 6' run you would only lose 1.5 V.

I have a hard time believing that an upgraded pump would flow less than stock pump at the same power level. I'm only pushing 7psi or so

tom ... i think what is being said is basically the stock wiring isn't powering the bigger higher flow aero S pump... so its not giving correct flow... however if yours is ok.... then....

My initial pump started going bad after 3-4 months, but you've probably put yours through a lot more wear and tear. Checking my air fuel ratios is probably my next step. Maybe a code reader can tell me about how the pump is performing too. What about E46 M3s that use this in their HPF turbo setups, I didn't see them upgrading wiring in their install video. Is our car that different?

I think we're good with the stock fuel pump. Thanks a lot for your constant feedback, i just cancelled my order of aeromotive fuel pump just because of this thread and your feedback. |

ESS VT2-525 upgrade kit being ordered tomorrow
project 2.87" coated pulley was a fail. Too much belt slip. Car trapped 112mph in the quarter mile, compared to stock 7psi pulley hitting 116. I'm not only dragging this car, I have an autox session on Sunday. New goal is 430rwhp+ and 122mph trap speeds, with high 11s on street tires. Water/meth injection isn't installed because I can't find a proper adapter to make the stock windshield washer fluid reservoir work as a tank. Eventually. ETA for the parts and install is gonna be 4-5 weeks

ok so I should be OK since we're getting upgraded injectors. Thanks, that saves me some re-wiring labor.
Does the S54 crankshaft pulley have the same specs as an E46 M3? I'm pretty sure

ESS designed this kit with 9 psi on 525 and stock everything with euro headers, this means in their setup 9 psi are not being inhaled in the head. If your head is flowing a little better this number will drop. If you install a US header for example with everything else stock and 525 kit you will read 9.5-10-10.5 boost. Another factor that affects the boost reading is engine load, the more the engine is loaded, the more boost you will see on your gauge since the engine is not capable of swallowing that much boost. in your case, since you have a mechanical advantage 4.10 gears, the engine load will be slightly less in 5th gear and will therefore swallow more boost. 7.5 psi on 8000 RPM is not a bad number for this kit trust me. If you have time, remove all your pulleys and have a machine shop make exact copies of them except with adding 2 ribs on CAD. It shouldn't be very hard. I was contemplating drawing these in software and 3D printing them with titanium in some shop, won't cost a lot. |
