Alright so as the title says, I'm going to do a supercharger build piece by piece. Street driven, daily driver, I'm looking for about 375_400 whp, and wtq. My first question would be injectors, do they have a direct plug in 42# injector for my car or would I have to be an adapter, etc and should I use a Vortex v1, v2, or v3?... thanks in advance and I'm sure to have plenty of questions to come, IM looking for parts as well and haven't had too much luck with classifieds. Accepting Andy advice and help

I have a v2 with 3.33 pulley, snow stage 2 meth injection, anderson powerpipe, 42 ford racing injectors (direct plug and play) and through an auto I put 425 to the wheels. Hope that helps a little.

For the head unit I'm not concerned about the sound, just the reliability, I've heard that 400 is closing to the limit for the internals?

I also can't seem to find the 42#'s I see 47# and 39# >. < and I'd love to be able to post my want to buy list but I'm not getting the option for some reason

I remember hearing the green tops 42# injectors from ford got discontinued..I may be wrong. 39s are from the cobra I believe. Personally I'd avoid adapters just cost more money. I bent a rod with 360rwhp. The safe safe part is all in the tune. But if you have a hiccup in a fuel component like I did, there is no safe on factory stuff. Just a heads up. On that note how many miles are on the car? I only ask because I found my fpdm to be lacking cost me a lot of money, if you get a boosta pump it won't matter, if you don't you'll want to make sure the fpdm is outputting what it needs to, as well as the charging system.

Just clicked over 91xxx not to long ago actually, so it's getting up there a little bit, it's my daily driver though, so while I'm getting parts together the miles will be going up

just something to be aware about. I had 118k on my car or there abouts. It worked great for na, but when i put the sc on it stressed the fpdm, and it wasnt able to output enough voltage to get the pump pressure up. put that on top of a bad alternator that heated up and lost voltage up top and i wasnt able to support 360rwhp with a ford gt pump. Im only telling you this because it took a lot of time and some good tools and friends to track, and most people dont do the work themselves like i did, so it can cost a lot, on top of the dyno time i had to repay to get done...twice...led to me getting a return style fuel system. In hindsight its fairly easy to check for, but not without full throttle runs and a volt meter, and a long road with a high speed...or you do it on the dyno, but obviously that cost money. On a side note i have a brand new ford fpdm sitting in my garage that had about 500 test miles on it before i scrapped the return less system. If you ever end up needing it, 75 bucks id let it go. Also if you want any info on what your looking for with that stuff let me know.

Boost a pump or the fpdm is the question which would be a better buy , is there a possibility that the fpdm would be over stressed and go bad sooner with the s/c on it and by sooner I mean noticeably

Bman2000

thats a good question. i cant answer that very well unfortunately. The reason i avoided buying a boost a pump was because my tuner doesnt like to use the if he can catch people before they buy them. The bottom line is if you need a boost a pump, you are running a pump that is too small for the power, or in my case have issues with other parts of the system. Its a bandaid basically. The fpdm overdrives the pump by allowing more electrical current than the fpdm can provide. So even though people have been using fpdms without too many issues that i know of i find it more likely that you will shorten the life of the pump by having a boost a pump than you will by having the correct size pump and working fpdm and charging system. But thats just my opinion.
