Ford Mustang Intake Comparison - Spin The Throttle
Probe EFI Spyder
We had high hopes for the Probe Industries EFI Spyder intake manifold, which consists of a single-plane carburetor intake drilled and bunged for fuel injectors and fitted with an elbow designed to accept up to a 90mm throttle body. For $749 Probe sells you the aforementioned intake and elbow, as well as the necessary fuel rails and hardware to adapt the intake to your Mustang. As you might expect from a single-plane carbureted manifold, high-rpm power at the cost of torque was its specialty. At 7,250 rpm the EFI Spyder delivered 473.0 hp, and down at 5,750 it supplied 384.2 lb-ft of torque. Reichard Racing's Billet Upper
The latest player in EFI Ford intakes is Reichard Racing's Billet Upper intake, designed for use atop the Trick Flow lower. As you'd expect from the name, the Reichard intake is carved from a piece of billet aluminum, hence the whopping $769.95 price tag from Holcomb Motorsports. Reichard promises 400 cfm per runner from this intake, and it certainly shined in our testing, where it cranked out 474.2 hp at 7,250 rpm and 386.9 lb-ft of torque at 6,000 rpm.

As with most tests, everything isn't just black and white. In looking over the numbers, it turns out we really have two intake tests: Victor 5.0 versus Trick Flow R-Series, and EFI Spyder versus Reichard Billet Upper versus Vortech Mondo Box (the Trick Flow box is just for show at this point). It's also worth noting this is how they ran on our combination, so your mileage may vary. But if you have a similar combo, or are thinking of building one, take note. Of the two short-runner intakes, the R-series makes better torque down low and the Victor 5.0 makes a lot more power up top. Of course, the Victor 5.0 is another $94.00, so if you want a little more power, you gotta pay for it. On the high end, it gets tougher. All three intakes made power in the 470hp range, but the Reichard and Vortech intakes made a bit more torque across the powerband. Though both the $769.95 Reichard and the $468.00 Vortech also require a $250.00 Trick Flow lower to seal the deal, the Vortech is still the bargain of the three at $721.00 total, while the Spyder is in the middle at $749.99, and the Reichard is at the top of the Visa bill with a $1,019.95 total price. It seems that to really make power you have to pay to play, and we didn't even factor in the required phenolic spacers for throttle linkage and valve cover clearance with several of these intakes. Even with the prices required to do it, it's exciting to know the technology is available for a whole new level of naturally aspirated EFI performance, and it's not just from one source.
