BOOST-IT FUEL SYSTEMS

[NM]

I run an aeromotive 1:1 @ 55 psi. It should be loaded pretty hard when its wide open pulling all the weight it will pull, it is loaded for shorter periods though. I am still interested in this system as it would also offer better atomization and cooler charge temps with the injector farther up the runner, I still like the timing control on my rapid bike though. Has anyone tried running just the timing from the rapid bike yet? I guess you could just zero out all of the rapid bike fuel map?

Well you are running alot of fuel pressure, so that will help. Essentially you are making a 450 cc injector a 505 cc injector because of the extra pressure. All fuel injectors are rated at 43.5 PSI. More pressure is not the ideal way of getting more fuel but it does work and people have been doing it for years.

So far all the Rapid Bike guys have just taken it off completely. It is just so much extra wiring and more to go wrong. My system is just power, ground, tach signal, and vac line, so very simple.

Hi Neil , does this system fire all four injectors at the same time ( i think MCX runs this way ) or does it fires one injector at a time on cylinder intake .
Thanks

They are batch fired like MCX and like the stock system is. My injector harness has a common power wire but seperate signal wires to each injector unlike the MCX harness which is wired in series. The seperate signal wires allow for the injectors to be more precise with the opening and closing time vs a single wire that has to handle all of the Ohm's through one wire. Hope that helps!

all of the Ohm's through one wire.

I think you mean all the current (amps) through one wire.

Nope, meant ohms. Amperage is the amount of current in a circuit, and these injectors use very few amps, in fact my whole system uses about 6 amps at the most.
Ohm's are a measurement of resistance, and these injectors are all rated at between 12-14 ohm's. When you run them all through one wire and hit them all at once, then that one wire carries all of the resistance(ohm's), vs my harness which has seperate wires to each injector.

I understand what you're saying....injectors are not wired in series. Best way for sure.

MCX injectors are! Ive never seen it before either.
Here ya go. I'm not suggesting the MC harness does not work, because obviously it does, I'm just saying mine will not have the effects of high ohm's through one wire.

Pic of BOOST-IT harness. This harness does fit in a MCX intercooler btw.

Powderlites BOOST-IT kit.

Here are some more pics of a Powderlites install if anyone is interested.

The MCX Harness has the injectors wired in parallel (electrically speaking), not series. I like your harness better but their way works fine.Their circuit is merely 3 resistive loads in parallel. Their wire gauge sizing is definitely adequate for the circuit current draw. The "effect of high ohms through one wire" is something I don't agree with. FWIW I am an aircraft electrician by trade with 30 years experience. The F18s that fly over your head on occasion probably still bear my fingerprints. Anyways , keep up the good work.

I have to say, that is pretty cool. I would absolutey love to pick your brain someday. MCX has pioneered the turbo sled world and I have nothing negative to say about them. I am having alot of fun helping the guys that have struggled with getting proper tuning on there turbo sleds. I myself have gone through a few years of day to day driveability issues and poor fuel economy, but finally found the answer because of MCX. I just found a way to adjust it on the hill. Thanks for the feedback Roest, every bit of info does nothing but help.

Just imagine what the MCX 180 kit guys could do with this system. Continue to run the stock injectors with the MCX box and blend in this new fuel system. Sure, you would need head shim. Could most likely skip the intercooler and inject Meth if the inlet temps were to high. But this would be the making for one insane "upgrade kit" lol

Great system.....

I cant quite tell from the pictures. Do you need to open the pelican case to adjust the dials, or do the dials protrude through the case?

Also, i see you removed the factory sensor from the powderlites intercooler on the left hand side. What is the reason for this? Where is the sensor installed now?

Thanks.

You just have to flip the lid up to make any adjustments.

Good eye on the intake air temp sensor. There is a reason for this. It's the same reason MCX does not put it in the intercooler. I will explain it to you when you order your kit.

Neil... Are you not in Mexico right now? Holy crap buddy If you got the same enthusiasm next year same time your customer service will be hard to beat! lol

 

[canucklehead]

In Mexico and guys actually got what they ordered??? Maybe he will run into Halverson down there and give him some business advice... when you take peoples money you're supposed to ship them product.

 

[richyrich]

Maybe you could let us all in on this , i have a Alpine kit and the factory intake air temp. senser is installed in the upper part of the intercooler.!
Thanks

No issues with Neil, hes a good guy who willing to talk with anybody and help all. Halverson's a DOUCHE and has ripped a boat load of people for a ton of money.

Yup, I sure am. Have to keep the family happy too.

I have been answering PM's and emails though, so it's pretty much business as usual, and I will start shipping again when I get home.

 

[gus bohne]

Yes he has been answering emails,, BUT he didn't tell me he was in mexico !!!!

Slacker @!

Canuck, can't wait to see the new ride,, good luck man..

Im almost there. Just got to ask some more questions. Figured that it would be best to ask them here in case others have the same question.

So the Nytro you did the testing on, did it have a head shim? What about changes to cam timing? My biggest concern is that these modifications on my engine have changed the engines fueling requirements to the point where they are different enough that the factory ecu tune is not adequate. Maybe its so small of a difference for vacuum that it doesn't matter?

Thanks again.
