What number shrunk as these power gains were made?
One number that shrunk as these power gains were made was the deck height. Today’s Pro Stock engine block is nearly unrecognizable compared to the iconic OG motors of the ‘70s, so here’s a quick history lesson in what has become NHRA’s most complicated division in terms of internal combustion engineering.
Why are intake manifold runners shorter?
Longer runners are simply a restriction at higher RPM. Again, the goal was to get shorter runners without increasing the size of the plenum —which is sized according to the airflow demands of the engine’s displacement in naturally aspirated carburetor applications. Too small a plenum will starve an engine, and too large a plenum may interfere with the velocity of the charge into the cylinder.
What would have happened if the intake manifold had not shrunk over the years?
The intake manifold would have grown as “wide as a house” if the deck heights had not shrunk over the years.
Who drove the DRCE engine in 2012?
Aside from the 2012-13 championship runs from the highly talented Hemi drivers of Allen Johnson and Jeg Coughlin Jr., the DRCE engine has dominated the Pro Stock ranks since Glidden’s glory days. Pro Stock fans, of course, may bring up the questionable victories by one Mopar team in the ‘90s, but Pro Stock has been pretty much a GM playground over the years. This past year the 4th-generation DRCE4 cylinder block was released to racers, and the allowable deck height reflects the continued shrinking of that engine spec.
Why do they raise the intake port?
Cylinder-head specialists were driving this trend. They started raising the roof of the intake port to achieve a more direct pathway for the air-fuel mixture.
When was the V&H drag engine made?
Designed in 2001, the original V&H two-valve drag engine had very short pushrods. New rules made going back to what they’d had history. Hines started work December 23, 2012, and was able to fire the new two-valve-per-cylinder, long-pushrod engine on February 23 of last year, leaving him less than four weeks to build it into a potentially winning motorcycle before the first national March 14–17 in Gainesville, Florida.
How much pressure does a spintron valve train need?
This current big twin revs to 10,000 rpm, and to do that with two valves requires 500 pounds of seat pressure, rising at full lift to between 1,200 and 1,400 pounds. Part of development was running a complete valve train on a Spintron, using non-contact position sensors to analyze valve motion.

Further adjustments are made to machine weight as deemed necessary. Power is in the vicinity of 375 hp, and the 2013 V&H bike made a best run of 6.82 seconds at 197 mph.
Does the Suzuki Pro Stockers have a two valve engine?
Up to that point, Suzuki Pro Stockers had two-valve-per-cylinder engines based on the GS1000. NHRA accepted this argument, so Vance & Hines asked to be able to use modern technology as seen on Harley-Davidson 's V-Rod. V&H even asked to be considered to design and build the four-valve Suzuki, since the company is a longtime builder of many of the Suzuki engines and parts in the series. To Byron Hines, such a project would likely have to cost $500,000 to $750,000. Suzuki's choice eventually fell on the Don Schumacher dragracing organization.
What engine is used in NHRA Pro Stock?
Very few people would argue with the statement that the ultimate step in the evolution of the big-block Chevy V8 is the GM Performance Parts engine found in today's NHRA Pro Stock race cars. Unlike some other forms of "stock car" racing, Pro Stockers must use contemporary body styles that closely follow the contours and shapes of actual production line cars. However, that's pretty much the end of the "stock" aspect of the class, as these are undoubtedly some of the most sophisticated racing machines ever to traverse the quarter mile, running deep into the six-second zone at speeds over 210 MPH. Under the stock-appearing sheet metal is a pure-bred tube-chassised racing vehicle with every conceivable modification honed to perfection by some of the brightest minds in drag racing.
What ignition system is allowed in Pro Stock?
As for the ignition system, NHRA rules specify which one to use, and the MSD #7530T Digital 7 Programmable Ignition Control is the only system allowed in Pro Stock. I asked if different advance curves were used in different cylinders, and Johnson echoed his answer about different cam timing: if everything is right, all should be the same. Individual cylinder curves are just a band-aide for bigger problems such as uneven air/fuel distribution, and you're better off to address those problems. Asked about different advance curves in each gear, he did confirm that, as expected. As the engine load changes, the engine's ideal spark advance requirements change, and that is one of the virtues of the MSD #7530T.
How fast is Warren Johnson?
Winner of six Pro Stock World Championships, "The Professor" was also the first to exceed 180 MPH, 190 MPH, and 200 MPH in an NHRA-legal Pro Stocker . He was named as one of NHRA's Top 50 Best Drivers, and is a member of the International Motorsports Hall of Fame.
What compression ratio is used on a Sportsman?
When asked about the compression ratio, WJ quickly answered "15:1 ", which at first I thought was his attempt to see if I would accept this seemingly bogus answer. After all, on a Sportsman level single four-barrel engine, 15:1 compression is just right, and the "big boys" take it up a few points from there. Then Warren started referring to valve timing, and made a quick remark that you have to leave room for what makes the power- I'm thinking fuel and air here. Suddenly the lights go on, and I realize that static compression is one thing, but it is the dynamic compression ratio that actually makes horsepower, and dynamic compression is a function of valve timing and volumetric efficiency combined with static compression. So 15:1 may seem a bit anemic for an ultimate level engine, until you factor in the obviously well researched valve overlap design (typical LSAs on a Pro Stock engine are rumored to be in the 117°+ range), and the super efficient dual four-barrel carb induction system, capable of dumping in so much fuel that more compression might simply not leave adequate room to prevent hydraulicing. He didn't even mention the detrimental effects of excessive piston dome height on flame travel in the combustion chamber; that would seem to be obvious.
Why do you need a shorter rod?
A longer rod simply puts the wrist pin bore higher on the piston, which lets you build a shorter, lighter piston. By the same token, a shorter rod is lighter than a long rod, so you need to shorten the deck height to keep everything compact.
Can you rev an engine during a burnout?
which got the response "sometimes, especially if the driver gets overly enthusiastic on the burnout". For those of you who haven't been there, it's extremely easy to over-rev an engine during the burnout, since the tires are spinning so freely that the engine is essentially operating under a no-load condition.
Is a DRCE 3 a big block?
When I approached WJ for this interview, he was quick to point out the obvious fact that the DRCE 3 Pro Stock engine is technically not a big-block Chevy, and he's right. Not a single stock big-block Chevy part fits these engines, yet the fact remains that they started out as a direct replacement for the Rat motors that were being used by Pro Stock racers in the 1980s. At that time, Chevy, Pontiac and Oldsmobile divisions were all vying for a piece of the Pro Stock market and all three were developing cylinder heads to fit the big-block Chevy since the "corporate engine" policy allowed any GM vehicle to use any GM family engine. Why they all developed heads for the Rat motor is not hard to figure out- it was then and still is a much better engine design than either the Pontiac or Olds big-blocks, and this family rivalry gave us the Pontiac Pro Stock head, the Chevrolet Symmetrical Port head, and the Olds DRCE head, all designed to fit the big-block Chevy block. WJ was campaigning for Olds at the time, and his input and engineering expertise was eagerly accepted by the Olds engineers. Since Warren was never one to leave well enough alone, he led the development of not only a DRCE head, but also took advantage of the opportunity to develop a unique block that addressed several areas of weakness in the original big-block Chevy design, and every aspect of the cylinder block was refined to improve the performance and reliability of the GM big-block powerplant. The current NHRA rule book specifies the use of DRCE block #24502572 or DRCE 3 block #25534402, and DRCE cylinder head #22530959, DRCE 2 head #24502585, or DRCE 3 head #25534404 for all GM vehicles.
