^^ This is a good idea
and @Davedacarpainter 4.9x's in the 1/8th is 7.7x's in the 1/4And it will still make a beer run after any event if need be! :beer emoji:
OUCH!! Luckily that was testing and not an actual eventWell nearly any event:
Update to this post that i posted 2 minutes ago...So i just got off the phone with a guy that used to build motors for Carol Shelby and he helped me answer a lot of my questions and i thought id share. Although i found the answers to a lot of my questions i do have some new ones. He told me that there is a good chance that my 14lb injectors will support the power and added boost of the 10psi pulley due to the low rpm the engine turns. The way that he told me to calculate whether they will work or not is to find out how many gallons per hour the fuel pump is. This is where my first new question arises.
Does anyone know what the gallon per hour rate of the piggyback pump included with the vortech kit is? I remember seeing this somewhere but cant seem to find it again.
He told me that you need about a half pound of gas for every horsepower. Based on the previous statement that the 8-12lbs is around 350hp the figure is 175lbs of fuel pressure. I'm wondering if the combined fuel pumps can support that. He had given me a way to test it but since i remember hearing the figure before i thought id see if someone would know it before i go make a mess with gas. Ill give Vortech a call and see if they know the figure. Hopefully i can save myself from having to buy the new injectors.

I called Vortech and they told me that their piggyback pump is 155 liters per hour. Converting this to gallons this comes out to around 41gallons. With one gallon of gas weighing about 6 pounds this comes out to the pump having 246lbs of fuel pressure? Can someone tell me if this is right. I believe that the math that i did should produce the correct result but honestly just don't have enough knowledge on the topic.
The problem is those boxes add more retard..........Might not be the best choice for you if clarity is what you're looking for.I wish I had a retard module, maybe I wouldn'd be so confused
The issue with turning the fuel pressure up is this.... it will put strain on the pump. None of us use an fmu anymore, we use injectors sized for the application at 43.5 psi and utilize a rising rate fuel pressure regulator....The chart is a little confusing due to the fact that the kit advertises more horsepower than the chart says my injectors can handle and the kit doesn't require new injectors. With the added fuel pressure on the rail due to the fmu included with the kit, it seems like they might be okay. The guy that I spoke with on the phone whose built a million motors was telling me that it usually isn't your injectors flow rate that can't keep up it's usually the pulse rate. He said that they had a 750hp motor running on 24lb injectors due to the fact it only turned 7000 rpm. With my little v6 only revving to 5grand I'm sure the injectors shouldn't have a problem keeping up the pulse rate.

That's just where the older v6s red line. If I'm remembering correct the rev limiter is set at 5200. Seems like being down two cylinders from the v8 it should rev a lot higher but it doesn't.Why would your V6 only turn 5000 rpm? Is something wrong with it?
I think at this point I'm just going to go with a bigger fuel pump in the tank, bigger injectors and eliminate the piggyback and fmu. Sounds like that's the safest bet.
