Jeep Strokers

http://cgi.ebay.ca/SB-Fuel-Injectors-24 ... m153.l1262

will these fit in a 2001 wrangler 4.0?

TIA

The injectors pictured will fit pre 99 jeeps, not your 2001, due to the newer style harness you have. You'll have to find ev6 style connector injectors iirc.

Not only that they will be flowing too much fuel for a 4.0l or a 4.7L

Those are actually the exact injectors I have in my 97 stroker. Runs fine, although I have never tuned it. I dont think they are using too much fuel as I still get 16-17 mpg, same as before the stroker.

You did see that at 50 psi (one PSI more than what your system is pushing) they are putting out 27lb? That is a little much for a 4.7L. In your case at 49psi theyw ould putting out 26.6lb. I had a set of ford Cobra injectors that flowed similar to those. With out the Apexi interfering it was putting out greater than 10:1 at WOT, i.e. rich. And my wideband only goes as high as 10:1, so it may have been richer. I am swapping them out for a lower flowing injector.

If you use this equation and expect 250HP:

Injector flow rate (lb/hr) = [Expected HP x 0.5 (BSFC)] / [no. of cylinders x 0.8 (injector duty cycle)]
( 250 x 0.5=125) / (6 x .8=4.8) = 26.04


Actual injector flow rate = Rated injector flow rate at 50psi x square root of (FP/50PSI)
27 x .98 = 26.46

Thats pretty close, and should work fine right?

Those equations don't really work. I've tried several of them and they all say like 26lbs. However, I have ran rich with 26lbs and for a stroker it seems every one is using 24lbs.
