Building Ford Race Engines for the Daytona 500

Roush Yates FR9 EngineHere's a fun video I had the opportunity to produce for my friends at Roush Yates Engines a few months back.

They wanted something to celebrate the beginning of the 2015 NASCAR Sprint Cup racing season, so we came up with this concept about building a Ford FR9 race engine that will go into one of the cars. Of course, after an entire off-season spent on research and development, most of the guts of the engine were still top secret--so a few steps had to be left out. Still, it's always fun to hear a Cup engine on the dyno.

And by the way, Penske driver Joey Logano won the Daytona 500 with one of Roush Yates Engines' Ford motors. Not saying this video was a lucky rabbit's foot, but if any Cup teams want to hire out the Horsepower Monster for a video next year just in case, we won't complain!

One of a Kind V12 Ford

Jan Baker had an idea. A longtime racing fan, he always felt like Ford should have built a V12 engine to compete with the likes of Ferrari at LeMans back in the '60s. Of course, Ford never built a V12 for racing, so Baker took matters into his own hands and built one himself. Baker…

Easy Rev Limiter Tuning with a PerTronix Flamethrower

Pertronix DistributorOne of the pleasant surprises when working on The Horsepower Monster's 427 Stroker Engine project (if you haven't seen it, check it out here) was the built-in rev limiter on the PerTronix Flame-Thrower distributor we used.

The PertTronix unit is a really nice piece because it puts out a nice strong spark, the mechanical advance system is easily tuned for both maximum and rate of advance, and is really well made. But that's the obvious stuff. What we also came to appreciate during the built is the ingenious rev limiter the engineers at PerTronix have baked right into the Ignitor III module for the distributor. Adjusting the rev limiter is pretty easy and requires no extra equipment.

But seeing is believing, so we thought we show you the process here.

How to Measure the Chamber Volume of Your Cylinder Heads

How to CCBeing able to check volumes is critical for anyone building engines. You can calculate your engine's compression ratio based on what you think the combustion chamber volume in your cylinder heads might be, and what the catalog says the volume of the valve pockets in your pistons should be--but you are really just hoping unless you can verify it.

Checking volume is as simple as pouring liquid from a marked buret into the space your are measuring and then seeing how much remains in the buret. Of course, there's a little more to it than that, and we'll show you all the tricks in the video.

Checking combusation chamber volume is by far the most common use for a CC'in kit, but once you've got the particulars down it can also be quite useful to check intake and exhaust port volumes, cylinder volume at piston TDC, intake manifolds, heck, anything you can think of.

And by the way, the CC'ing kit I used in the video came from Powerhouse Products. The same is true for the cylinder head stand. The cylinder heads are aluminum Dragonslayers for a Chevy small block from Brodix that will be showing up again soon on our 427 cubic inch small block project engine. Check it out when you get a chance.

Secrets to Dialing in a Mopar Valvetrain

Like most Mopar engines, this 340 LA-series small block utilizes a shaft-mounted rocker system that provides superior stability but requires a few extra precautions during installation to make sure the geometry is correct.   There is no doubt that the stud-mounted rocker systems that are commonplace in small block Fords and Chevys are simpler and…

Fixing an Exhaust Leak in Our Project Camaro

Say hello to the Horsepower Monster's new project Camaro. First Gen Camaros have been highly prized for decades, and now the early '70s big grill cars are catching on with the Pro Touring set. We figure we'll be ahead of the curve with this '78. Plus, we're cheap.

An Up-Close Look at Holley’s New Throttle Body for NASCAR Sprint Cup Engines

After racing Holley carburetors for decades, NASCAR recently made the switch to fuel injection beginning with the 2012 season. But even with all the changes to the engines, Holley still plays a pivotal role in making these engines perform and survive the rigors of 500 miles of all-out racing. The famous carburetor manufacturer was tagged to build the throttle bodies used with the new fuel injected engines.

What many people don't realize (yet) is Holley uses much of the same design and technology in its street throttle body as the NASCAR racing unit. And the quality of both, honestly, is incredible.

I recently had the opportunity to work with Holley to produce this video showing not only how the new throttle body is being used, but also to pull the curtain back a bit on the new fuel injected Cup engines. A big thanks goes out to the engine builders at Roush Yates Engines and ECR who were willing to give us a behind-the-scenes look at what's involved and how Holley makes it happen.
