Re: 3.7l performance love

Hey Jeff, what did you gain from the 26lb. Injectors? Did you add them to aide with all the exhaust and intake mods?

Re: 3.7l performance love

The injectors were installed to supply a little more fuel over stock because of the intake and exhaust mods, espesially the exhaust. but the truck feels like it pulls a little harder from about 3000rpm up till about 5100rpmm before the power falls off at 5600rms. plus the injectors being only slightly larger then stock (21 LBS) i didnt really take a hit to fuel mileage unless i went wot.

Re: 3.7l performance love

That's what I figured. Thanks man.

What do you plan on doing next? Lightweight crank pulley? Port the stock intake manifold?

Re: 3.7l performance love

actually i do plan on an ATI 25% UD with the damper and i have been thinking about working the manifold, but i really want to go dual exhaust and heres how i want to do it;

im gonna start from the headers back and purchase a magnaflow y-pipe, but im gonna cut the flange off were it gose "2 to 1" and keep the "2", from there im putting on a pair of stainless works turbo-s tube mufflers and i will be keeping it dumped out the side like it is now. but at the moment tho, my primary concern is getting new tires to put on my srt reps

Re: 3.7l performance love

Just a suggestion but have you ever thought of running the two pipes into a dual in/out magnaflow? Might save on room and money sticking one muffler under there instead of two.

I had a kind of like what your planning on a 98 ram 5.9 where I ran 2.5" from the headers into a Dual I/O Flowmaster and out to 3" Duals angled out the back. Sounded like a mean sumbi+ch.

Re: 3.7l performance love

i agree on the money part, but the mufflers are small enough to work
