Upgrade Questions
 

Ok, I got some questions to ask the pros here. I just made my appointment to get my truck on the dyno in about 3 weeks. Before I go, there are a few things I would like to do right away. Tell me if I am wrong on any of these or if you have any other ideas. I already have a built motor (forged rods, pistions, and crankshaft). I would like to take the shifting up to 5500-5700 RPM's. I do plan on getting a more conservative tune for normal driving along with a performance tune for when I go to the track/want to screw around a bit.

I just bought new Autolite HT0 plugs.
I have a 2.80 upper pulley.

boost a pump setup (kind of a must)
4lb or 6lb underdrive pulley?
Ported plenum

Only other thing I was thinking about was possibly a camshaft, but that would more than likely cost as much as all the other stuff listed above.

Ditch the boost a pump. Buy a fuel pump which is capable of your fueling needs. My 2 cents.

Well what kind of fuel pump would you guys recommend?? I have looked around...but not too much. Is there one that would drop in that would use the existing
wiring?

+4 pulley is safer but with your built bottom end the +6 should be great with the proper tune.

I have had bad luck with the HT0's gapped anywhere from 28-35. For whatever reason they just go bad and the engine misfires. Change the plugs and it's all good again. They are the only game in town though. I have a stock fuel pump on mine.

I have NGK's in my late year 2008 FX4 with a Procharger and I never do a thing to it except drive it. It is MUCH more reliable than my 2004 with the Roushcharger and HT0 plugs. They both boost about 9-10 but the 2004 is tough to keep tuned and running properly. Coils, plugs, MAF, TB etc...It is high maintenance.

Ok, so here are a few more questions. What brand fuel pump should I get that is a direct replacement? Also where would you guys suggest I get my plenum ported? I would like to find a place that could sell me a used one that is already ported and then I can send my non ported one back. I don't care if there is a deposit on it or not, I just want to be able to do it in a day and not have to wait a week since this is kind of my daily driver right now.

Will this pulley work? Otherwise I am not %100 percent sure where else to look. http://www.ebay.com/itm/99-04-SVT-Lightning-Harley-Davidson-F-150-Supercharger-Crank-Pulley-Kit-6lb-/390581256558?pt=Motors_Car_Truck_Parts_Accessories&hash=item5af075016e&vxp=mtr
Also, would this be a good fuel pump http://www.ebay.com/itm/191129076573?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT

And I am guessing I will need a new belt with the different lower pulley? Does anyone recommend a certain size and brand belt?

once you've installed a hi flow fuel pump let me know if it helps you not getting lean, because as of now I can't find a way to provide my engine with more fuel

about your pulleys, I have a 4lb lower and a 2.8 upper, dyno analog gauge is reading 11PSI, my digital boost gauge is reading 13-14PSI, I've been ignoring my gauge for now, I'm making 420/520 and my roush blower (1.85L is ported), exhaust is restricting, I'll go true dual soon

I'll be getting cams, and I might switch back to my 3.0 upper to loose some boost

how do I find that out? dyno spreadsheets? I have the files but not sure how to read them

Crash, I am assuming that when you are talking about a "sock" for the fuel pump, you are talking about the pre filter or is there something I am missing?

would it not make sense for you to just sell your Roush (1.85L) blower and get a bigger blower? like at least a whipple 2.3L if not then get a crusher 4.0L or something as your engine is built?

because your (our) supercharger is so small, it just keeps heating up and you are loosing efficiency, I called Roush and they told me that after 9-10 PSI the blower isn't as efficient if you increase boost because the volume of air is so small, thoughts?

so far the only official answer I got from JDM regarding the fuel pump issue is to go with a twin pump system @ $1500

I think in an ideal world for those trucks it should be as this (correct me if I'm wrong)
built engine
2.3L or 4.0L or the blower that sticks out the hood
blower cams
twin fuel pump
built trans
built diff
traction bars
lots of boost

I am going to be putting in this new fuel pump this weekend. I am a bit nervous because I cant seem to find any "how to" videos anywhere online. I guess we will just see what happens. Worst case scenario, at least the pump I am taking out still works if I need to put it back in. I will update you guys once I get it in and running. Hopefully this will solve any lean issues when I get my other mods done.

Look forward to seeing how this works.
