Jeff S- I'm still running the fuel system with a 255 high pressure pump no external, 42psi injecters, pump gas with a bottle of octane boost
3922 plugs with out the box 6037 box stock edelbrock heads,
the A/F was up and down from 12.1-11.8,before the 3in exhaust the a/f reading was 12.3:1, the 3in exhaust must of richin it. My intake manafoldis a TFS-R untouched, with 1 5/8 longtube bbk headers and a TFS stage 2 cam, I have no FMU or chip. thats pretty my set up, oh its a 331 with 8.7:1 compression, I have plans for a fuel later on when I replace the heads.
thanks

Your two cars (Jeff and Tony) are very similar. You both have lx's, high HP 331 combinations, and Steeda wings.
Both of you ![[patriot]](graemlins/patriot.gif)

forced331,
I'm curious what your peak torque was with the R-series intake? Also at what rpm where your peak HP and torque?

The guy at the dyno let off @ 6k rpm, horsepower was still climbing acording to the graph. 6 months ago I dynoed it I went up to 6400 and my peak was at 6250 who knows with the 3inch. i will try it again and go to 6500 when I get a better fuel system.

Yes, this work would cost just about that! That is why the system will most likely never be produced. The kit and work are not available. Sorry.

It takes a lot of time to fit up and weld short pieces of bent tubing.
