Breaking Ground: EFI Intake for Two-Valve Modulars

Despite running into some minor first-production-run bumps, we decidedchanging a 4.6 intake manifold is actually easier than swapping an EFI5.0 intake. That's great news for the future of modular hot rodding.Here Johnny and Sam drop the Reichard intake into place.

After lining up all the intake bolts, Johnny torqued them in aninside-out pattern to 22 lb-ft. Don't put too much muscle into these oryou'll ruin the threads in the cylinder head.

With the intake secured and all the connections made, the last step wasto install our Accufab throttle body. Reichard set up the intake to putthe throttle body in the same location as a '99 Cobra. This means thestock linkage will work, and you just have to rework your Mustang'sinlet tract.

To make our supercharged combination work, we ordered '99 Cobra ductworkfrom ATI-ProCharger for our P-1SC. The alignment was just right, but wedid have to relocate the bung for the breather. This meant Johnny had tobreak out the welder and move the bung from our original tubing to the'99 Cobra pieces. No big deal--as long as you can weld.

Here's the finished product. It sure upgrades the looks of our Two-Valveand gives it that racy cachet. But, you probably want to know about thepower. Well, even though we knew our combination wasn't ideal for thishigh-end intake, we did run it on Coastal's Mustang dyno. The resultstold us our stock heads, cams, and exhaust manifolds were restrictingour performance potential. The intake lost bottom-end torque and power,and it was practically a break-even at the peaks. To do this intakejustice, however, we really needed a modified engine and more rpm. We'llbe curing that in the near future, as we plan to install this intake onour Livernois 5.0 stroker and run it with Steeda's new off-road TechTransfer calibration. We'll also be testing the round-throttle-bodyversion on a naturally aspirated combination, so stay tuned for more onthis pioneering intake manifold.
