The latest rumblings in the Ford universe
Second WindWe had the opportunity to check out the prototype of VMP Superchargers’ second-generation Twin Vortices Series supercharger (www.vmp-tvs.com) in early March, and this unit should take the performance of this supercharger breed to a new level.
As you know, inlet restrictions are the bane of positive-displacement blower performance. The more you can free up airflow on the breathing side of the supercharger, the more efficient and powerful the results will be. Working in concert with Roush Performance, VMP (www.vmptuning.com) has completely redesigned the inlet side of the tried and true 2.3-liter TVS supercharger.
The 3D-printed prototype that we laid our paws on had its integral inlet elbow removed to illustrate just how much larger the Gen II opening is versus a traditional 2.3 TVS. At first glance it seems almost twice as large, but the official specs haven’t been released just yet. What we do know is that more than the size of the inlet has been enhanced. VMP has taken 7 years of TVS experience and put it to work optimizing the inlet-to-outlet flow of the unit by turning air into the rotors sooner and removing and bumps are obstructions in the air path.
We can’t wait to see what a GT500 can do with this enhanced TVS.
5.0 FeedbackFox Army
I had an ’87 Fox, and I loved that car. I sold it when I purchased a ’67 Mustang and a ’67 Bronco, both of which I still have. If I had to do it all over, I would keep the ’87 and work out the problems it had, but I chalk it up to being young.
Anyway, I love the magazine and I the content you present. Personally, I like the ’80-’93 Mustangs and the Terminator era best, with the SN-95 to New Edge coming in third. I would never own a Mustang newer than a Terminator, save for maybe a Shelby, but I am not all that into Shelby Mustangs, past or present. While I love Carroll Shelby the racer, the cars and their followers are not really my thing.
I do not care for the modular engine at all, including the Coyote. I would dump the new engines in favor of a carbed small-block bolted to a tubular K-member in a moment. I would swap in an LS before I messed with one of the modular messes—and this is coming from a guy who never bought a Chevy. All that said, I don’t hate those things either.
To me the people that poke fun at Fox-era cars do so because the current V-6 has more horsepower than the Fox did from the factory. What they do not realize is that it was pretty easy to take that 220hp 302 and turn it into a 350-400hp 302. Furthermore, you could do this yourself. The EFI was easy to tune and these cars were fun to drive. Living through that era was like the old days of muscle cars.
Also, you should take into account that the horsepower numbers are all up, but the e.t.’s are not. My ’87 ran 12.3 to 12.7 in the quarter with street tires naturally aspirated. With a 150hp shot of nitrous, I dropped down into the 11s.
It’s because the old 302s had more torque in the lower rpm than the new engines, which some people have no idea about. Yeah, a lot of cars have 350 hp—but at 6,500 rpm, where nobody drives!
The reason I subscribe to your Mustang is, while I have my own ideas, I really enjoy reading about all the cars and engines and performance parts. You guys have a great magazine, and I think you do a balanced job of covering all the Mustangs iterations, as well as performance parts for them. Keep up the good work!
Whoa, whoa, whoa, Dan. Let’s not get carried away! Don’t curse by suggesting an LS in a Mustang. That’s just blasphemy. You are well within your rights to prefer pushrod engines to modular engines. That’s totally cool. Brand X transplants are not cool.
Anyway, we like almost every Mustang from ’79 to the modern era. Sure, we have our favorites, but they all have their positive aspects. We don’t see the need to hate one and love another.
That said, we know the pushrod engines are torquey, but it’s hard to argue with the horsepower-to-driveability ratio available with modern engines. Thanks to the TiVCT in the latest Coyotes, they can make torque and rev to the moon.
