dyno chart 3.jpg
Dyno sheet, 3/21/03398 viewsSo, here is the final HP tally. See attached dyno sheets. Per Dave at JBA:

"Max RWHP: 412 at 5300 RPM - calculated at flywheel 518 HP
Max RWTQ: 444 at XX00RPM - calculated at flywheel (TBD)
Timing - unknown

Notes:
Dyno run stopped at peak HP (5300 RPM/101 MPH); car bounces too much
Good power - what kind of cam? good choice
Slightly retard timing and richen fuel mixture at max load per request"

It runs much better, and cleaner. Spins 'em up in 3rd gear very easy now - have to be very careful when romping on the gas above 3K RPM! The idle seems too low - about 600 RPM - but they say I should leave it there. I am pretty happy with it (even if I am a little short of my 550 HP target). I can always install a 12 lb. blower pulley later!

MAF, air cleaner, pop-off valve.133 viewsBIG K&N air filter on Pro-M 77mm MAF.
bias cable.jpg
CNC brake bias adjuster cable routing147 viewsThe cable is tie-wrapped to the 3/4" pedal box tubes in a few places to minimize 'whip'. Lube up the adjuster rod (balance beam) before you install the adjuster or you may have a binding problem (I used some white lithium spray lube). I also punched an oblong hole in the footbox cover and have a 1" diameter thin wall grommet that I'll use to protect the cable from chafing and seal the footbox.

Dash connectors149 viewsDash connectors - Two 10-pin Jones connectors for high amp connnections (B+ power in and out, fan power, main ground, starter, lights, etc.) and two 15-pin Molex connectors for gauge and similiar low current wiring. Only 4 spare pins left (out of 50 total pins!)

main engine ground stud.jpg
Main engine grounding stud146 viewsThis is a 3/4" long 3/8" coarse thread bolt welded to the upper left corner of the trans tunnel (Mk II frame). I can access this by pulling the top cover off the tranny tunnel (I made mine removable). The ground strap goes to the left side head; then another strap runs over to the right side head (it's important to ground both sides when using AL heads).

batt box 2.jpg
Battery box - sides137 viewsI made my box with three pieces of 16 gauge 6061-T6 aluminum - two 8.5"x8.5" (plus 3/4" tabs on 3 sides) end pieces and one 12.25" long x 25.5" wide side and floor piece, bent in a U-shape and riveted together. Plenty heavy and secure for the job. You'll also need one piece 37" long and two pieces 8.75" long each of square 3/4" thin wall mild steel tubing to replace the pieces you'll need to cut out of the frame to clear the box. I also put in 1/4" drain holes in each corner of the box.

You'll also need to make a new top cover and find a way to retain it - like Forrest, I used some Dzus fasteners on the front edge and just tucked the rear edge under the overlapping rear trunk piece. If you are VERY careful when you cut the rectangular access hole from the trunk floor, you might be able to re-use the cutoff piece (but doubtful).

Other than welding in the new trunk floor tubing, cutting out the trunk floor was the toughest part, and that can be done easily (if carefully) using a Dremel or air tool with a cutoff wheel.
