Adding a nitrous spray bar to an intercooler is a proven way to lower the intake air temps and consequently give a more dense charge to the combustion chamber for more horsepower. We’ve been seeing more and more intercooler spray bars popping up on both performance and show-n-go cars.
The Honda Prelude may not be as popular as the Civic or the Integra, but it does have a rather large tuner following. One of the reasons that the Prelude isn’t as modified as often as other Hondas is that the model’s initial purchase price is considerably more than a Civic Si or Integra GS-R, since the Prelude was better appointed with options and a more powerful engine.
Ford engines are hot, and everyone—even non-Ford guys—are talking about it. The small-block Ford is an awesome package that is made even more awesome by Ford Racing and aftermarket parts. It has continually gained popularity as a high-performance buildup, as a Ford In A Ford engine transplant and as a replacement performance engine for vehicles that were optioned as such but were less equipped when new. With all of this activity surrounding the small-block Ford engine, it is safe to say that it is quickly becoming the small block of choice.
By now, we all certainly know that nitrous oxide is a performance enthusiast’s best friend. Nothing can wake up a sleepy motor like a quick shot of nitrous.
Performance enthusiasts are a funny bunch. They all seem to agree that “as much as possible” is the correct answer when asked, “How much power do you want?” But they certainly
disagree about the best way to get there.
While it is true that a turbo system does not have the instant response of a supercharger, the new Turbonetics T3/T4 Hybrid turbochargers are closing that time gap. Turbonetics has formed a complete lineup of products that take a T3 turbine section (in standard, Stage 2 or Stage 3 trim), that is then coupled with a T4 compressor section (T04B trim or T04E trim). The result is the T3/T4 Hybrid, which combines the low inertia and fast boost response of the lightweight T3 turbine wheel with the high airflow characteristics of the T4 compressor. These characteristics combine to make the T3/T4 Hybrid the turbo of choice for high-performance import applications.
Producing horsepower requires two major ingredients, namely, air and fuel. Of course, the two must be supplied in the correct proportions and at the proper time; but improving power is a simple matter of adding airflow. Naturally, additional fuel will be required once the airflow is improved, but the first item on the horsepower priority list should always be more airflow.
When you go looking to make huge power from your 5.0-liter Ford, the limiting factor will always be the weakest link in the chain. In the case of our supercharged 331 stroker buildup, the weakest link turned out to be the production block. Like most enthusiasts, we had no budget for a DART racing block or even a Ford Racing Sportsman block, but we decided to tempt fate nonetheless and go for a big power number on the dyno. Considering that the stock fuel-injected 5.0-liter was rated at a measly 225 hp, even a 300hp buildup would offer a welcome change in performance.
While the small-block Chevy is the popular engine choice for many enthusiasts, many are now relying on a Blue Oval heart for their performance bodies. With its link to Ford, the original body manufacturer for many of the classic cars we see today, the small-block Windsor-style Ford engine offers several advantages. When compared to Chevy, the lack of firewall clearance for a number of Chevy engine swaps is due to the rear distributor position of the engine. The front-mount distributor position is the more logical place to drive the distributor and the oil pump. Not to mention, it’s much more convenient.
We first wrote about this 565-cubic-inch Dart “Big M” engine, equipped with Dart Big Chief II Pro Stock-type aluminum heads, back in our October ’04 issue. The engine builder was Quarter Mile Performance in Chatsworth, California, and at the time, we called it “possibly the world’s most powerful four-barrel big-block.” It produced 1037 horsepower at 7200 rpm and 806 lb-ft of torque at 5500 rpm–plenty stout by anyone’s standards.
