The pipe is 2 and a half".

I got the sct tuner and the tune from Hemifever.

He is selling a complete sts/sct kit with intercooler and meth.

Check it out, he may still have it.

 

"Kenihemi" the mustang SVT blue injectors are 24lb injectors. I did not know they would even fit. If that is the case "bluealphadragon" you can to to a site called BUYFORDRACING.com and get those injectors for $220 or the 42lb injectors for $330. I would call around local shops to find a place that will do custom tunes. That is the best way to go. Just my $.02

 

The blue cobra injectors he is referring to are th 39# injectors. 39# at 39 psi. They flow 55# at 58 psi or 47# at the 2003 Ram fuel pressure.

 

I hate to say it but when your modding in this form your gonna break ****. So if you don't want to mess up your truck leave it stock.

It doesn't matter how well you follow instructions and do what your suppose to do stuff still breaks.

I hate to be that way but guys on all the forums always talk about fixing their ride up or making it faster but don't want anything to break.

My motto is if you can't afford to fix it then leave it alone.

Can you afford a new engine if you blow yours up? Maybe you'll get luck an they will warranty it but what if they don't.

Also if you don't know much about tuning then you best have it dyno tuned on the hottest day of the year with whatever grade of gas you use while the engine is sitting in traffic hot. If you go with SCT then you could get a 100+ octane program also for those cool nights at the track.

 

Color coding is only good for OEM Ford injectors. There is no industry standard color scheme.

FORD'S:
Orange=19lb
Light Blue=24lb
Red=30lb
Silver or Dark Blue=36lb
Green= 42lb

I've been supercharging cars for several years now and will say 6-7 psi on the hemi 5.7 should be no problem at all as long as the tune (timing and Air/Fuel ratio) is done correctly.

What is the compression ratio of the 5.7 Hemi?

 

Blacktop,

What fuel pressure produces the 24lbs?

My truck makes 59lbs of fuel pressure.

 

thank you everyone for your input, i have desided to go with krc performance's set up cause of the tuning they will tech support any problems or questions i have.

i have another truck so if this one sends a piston flying i'll repair it and drive my other truck in the mean time

i just do alot of research before i do or mod something like my nitrous kit i went with zex cause of there control box and i sprayed the hell out of it 125 shot and no problems it got my 04 QC 4x4 to do 13.605 at 98.98mph 60 foot was 1.92 i dynoed it later and was only putting 348hp/375tq to the tires on the 125 shot

so no im not worried about blowing it up its a hemi its indestructable!!!!!!!!!!!!

 

Here, check this page out. You're referring to what is called the "blue tops". We're referring to what is called the "Blue Giants". The 39# is at a much lower fuel pressure than the hemi pressure. And actually, the SRT4 injectors are preferred but these "blue giants" do work.

Any info on the SRT4 injector flow rate @ psi ?

Do the SRT4 injectors vary by year?

 

The 2003 srt4 "pink" injector is 50# at 58 psi. And it actually pulse flows more than the 39# cobra injector. The 2003 Stage 1 injector is roughly 55 to 58# and that Stage 1 injector is stock on the 2004 SRT4's. The 2003 pink injector is a good one to run for the avg application.
