So I am sending my motor out right away to start my build. Getting it fully built and going with a full Bridgeport. We are looking to finish at around the 5-550hp mark with the turbo I am running. I do plan to run a Water Meth system of course. My question is, what is going to be a sufficient fuel set up and ignition system for that high of HP? This question is more for the guys that are already running around the 500hp mark. I do have the twin power right now but I cant see it being a big enough spark with the water meth system (I could be wrong). Any and all help would be great as I need to start purchasing the systems to get the car ready for the motor. Thanks again in advance!

 

Look into the ign-1a coils. Those are pretty much the end all in ignition and they're very affordable. As for fueling, the popular set up is injector dynamics injectors in various sizes and FFE fuel rails. There is a company that sells a dual pump hangar as well [cj motorsports maybe?].

For a fuel system, you'll want the FFE rails, as well is injectors with an EV-14 body. That would be either just the off the shelf bosch EV-14, or a modified one such as ID or FIC. As for size, you should talk to your tuner about primaries but typically what people go for now are either 725cc or 1000cc primaries, and 2000cc secondaries. 725 would be more than enough for the primary but lots of people will overkill with the 1000s incase they decide to go bigger later. Doesn't hurt, as long as your tuner can work with them.

I would say the twin power and GOOD condition stock coils are okay for that level. any higher and you might consider a coil upgrade. Are you trying to make 500whp or 500bhp?

Also, what turbo and ems are you using?


Oh right, I forgot about the pump part. I wouldn't use just in tank pumps because then the issue of fuel starvation comes into play. What I plan on doing is using the stock pump (well, RP pump actually) in tank, feeding a surge tank with 2 submerged bosch 044s. The tank and pump assembly is made by Integrated Engineering. You should be able to find it with a quick google search. It looks like a nice piece and it will be more than enough.

 

Wicked thanx guys. Yeah I want to try my best to stay in tank as I have a big fiberglass stereo install in the hatch. As for the turbo there is no point even posting it as there is zero info on it. you technically cannot even buy it as a regular customer. Lets just say my buddy is running his supra at 896 WHP and still not at all pushing the turbo. I will be running a smaller exhaust trim then him of course. all the info is great tho! ill start looking into everything. As for the ID injectors I already had planned on running them. Intended to run ID1000 and ID2000 unless I get that new lower manifold that is direct injector per runner.

 

The Twin Power may get you there. Its been proven they supply around the same power as the AEM coils, but with a simpler setup. Since you have a Twin Power, you can try to go with it. I recommend a new leading coil. You can get one from Ray Crowe for around $150. With this, you want to run a quality plug. I run NGK race plugs in a 10.5 heat range on all 4. Banzai Racing sells them (R6725-105). Magnacore wires are also important.

As far as a pump goes, I am running an Aeromotive Stealth 340lph. It has had no issues at 454whp, and has been proven to 520. With your goals dual pumps are likely in the cards. Dual intanks or an outside will work. Do some research, there are many good examples.

I would also highly recommend a 4" exhaust. It will help.

With a setup shooting for 5-550, you are starting to press past the capabilities of a Power FC and its limit to the stock ignition. Looking into a Haltech or Microtech is something you should consider. The PFC is a great computer, but it was designed 15+ years ago. What were computers like then, compared to now?

 

Yeah I know the Power FC will be rough. I have been looking into the haltech and just waiting to see if I can come across a cheaper one somewhere. Thanks for all the info guys. Hopefully this whole build works out...have had the car for 4 years. Its time to go big

The powerFC can only go down to 1.8MS on-time, which with large primary injectors does not idle well. 725CC primaries at 6300 FT we can only tune down to 11.2ish AFR at idle warm. Its super rich cold with all the multipliers the powerFC puts in.


If you run a powerFC I recommend sticking to 650CC at most (which I run) and have no problems with idling at altitude. Just MO.

 

^ Negative lag fixes that lol

EV-14 1000cc primary injectors have been successfully ran with minimal issues.

 

What lag settings would you put in for these injectors?

need to get it up and running as best as i can
