Ok so I need some help again…
I have a hci built engine, and a vortech pushing about 12# boost, I have upgraded the fuel tank to a 03 cobra with two svt focus fuel pumps. I needed the upgrade because I ran out of fuel at 5K rpm during the original tune (running 42# injectors, lightning mass air, and 1 svt focus pump in original fuel tank) now I have the upgraded pumps and tank I need injectors, mass air, and a connection from mass air to supercharger (power pipe?) but what combination? I have been told conflicting stories and I want to get your opinion.
I have an SCT chip.

One scenario – 90mm SCT mass air, 60# injectors, and an Anderson power pipe.
Any suggestions or differenced of opinion?

Also what type of injectors do I need high or low impedance?

Thanks

I Have the pro-m 92mm?? maf and s deka 60lb inj, with the stock 03 cobra tank and pumps and have more then enough fuel, so unless your putting out more the 550-575 rwhp, that set up should be good.

good question, I am in the middle of my build up, I was gonna run the focus pump also but damn I may have to run 2 also? I have the 90mm with 42's 12psi Vortec,ported pi heads cobra shortblock,so we will be playing with the boost. [Big Grin] also, let me know so I can have my shiat here when we install everything. I dont want to wait for something I could have on hand.

I am now having a upgraded fuel line and rails put in. The 42# injectors are going back in too. I will need to go forward on the sct mass air, and power pipe.
I do not have an intercooler, i was considering water/methanol injection becasue of the additional expense 1500 bucks for an aftercooler is a bit steep.

any suggestions???

the reason I asked is because we you put the battery in the trunk it causes a lot of troubles like you have
