4.9 stroker done....now computer gremlins

[bradcarrier]

Hey guys, ordered up a Fast Stand alone fuel injection system for the jeep and a clifford intake. Fast system already got here, waiting on the clifford intake should be here by this weekend. After reading the instructons I have a couple of questions. Will I be able to use my current distributer? If so, will the computer still set the timing or will I need to ditch the setup since the factory computer will not have and info since I will be using the fast system and computer. If I do ditch the distributer will a HEI drop in? Thanks


Here is a pic of me hittin a double at the last race

Have not setup a stand alone on a Jeep. Did you get it going or installed yet?
When you mentioned stock head was it stock valves/ports? Our builds appear similar save for mine having lower compression for the turbo plans.

FAST system works great, idles great, keeping it around 800-850, system takes a little while to learn. On the fly adjustability. Nice kit.....

Nice.
What distributor did you end up using?
So how does it run, rev, power range? open shorter intake- what is your opinion?

After some great support from Keith at NewComer Racing I went with the clifford intake, he ported it a little for me, also recommended the FAST system. Its nice, set my rev limiter about 6K, definately makes some good power. I ended up buying HEI drop in dist from ebay $60 shipped, 12 degrees base timing, about 32 or so total. Had to wire up mopar external regulator for alternator. Way better than my OBD1 setup. Idle is perfect, sounds mean. Keith builds a hell of a motor. Now I'm still held back power wise by the exhaust, stock header, prob end up with a 3" collector system if I can make it fit.

One great reason for the FAST system is ability to set target A/F for idle, cruise, and WOT. Took mine close to 300 miles to get it dialed in exactly right trying different combos

disreguard vac advance, ended up, plugging it off

Just curious but would the banks header I am using on the 99 WJ (california emissions package) flow better than a single outlet header? Mine has Dual outlets on it for the dual cats, hence it would be possible to run Dual pipes from it down to a single 3 or 4" Y and out the back. It is more of an equal length shorty design than a full length header though... so not certain if it has any advantages other than larger collector potential?

[bradcarrier]

Ive heard duals are better, Keith @ Newcomer would prob know, most of his dyno runs have been with a big header with large primaries and a 3" Collector

After this season gonna get him to port my head(its stock other than bigger valves), then gonna get a header, not sure which way I will go, driveshaft and oil pan clearance is an issue right now
