Roger Manson’s Rapid Fire is so BangShift approved we can hardly stand it. This car started life as a sand dragger, was bought by Roger who then put it on the drag strip, got it to go 8.70s and is now pretty much obsessed with getting it to run 200 at Bonneville…all with a supercharged “half a 389” Pontiac four cylinder engine. The awesome is oozing out of this thing and we were thankful that Roger consented to allowing us to shoot photos and quiz him about the car. He hasn’t gotten to 200 yet, but he’s damned close and the fact that he is doing it by staying true to who he is makes it even better. Throwing a blown big block Chevy in the car isn’t going to happen. Roger has gone through 50 of these Pontiac four bangers since the mid-1980s and he’s one of the most knowledgeable guys in the world on the engine family and one of the few who has figured out how to spin them 8,000 RPM, make 600hp, and get them to survive….at least for a little while. More on that later.
Roger Manson’s racing career started back in the 1970s. He got into the world of four cylinder Pontiac engines because at the time he was doing some obstacle course, hill climb stuff that was divided into 4/6/8 cylinder classes. He decided to go four cylinder racing and settled on a Poncho because at 194ci, they were among the biggest displacement four bangers one could get a hold of and as it turns out, no one wanted them so he could get engines for cheap. He did all kinds of different stuff over the years but the Pontiac engines were always part of the program. In 1985, Manson bought the vehicle you see on the screen before you. That is to say he bought a version of the vehicle you see before you. The chassis was not as developed, the roll cage was different, and it was a dedicated sand drag race machine. The body is a hand made piece that isn’t one lick Jeep, although it certainly looks like one (even with the aero nose on it). There is some Jeep DNA still present in the car though. “This thing has 100″ of Jeep chassis in it because when the car was original built for the sand drags, it had to have 100″ of factory frame in it. Those pieces are still in there, even though we have updated everything a few times over the years,” Roger said.
For five years, it was the sand and only the sand for Manson until he decided to convert the car for the asphalt quarter mile in 1990. With a solid suspension, Manson along with his wife and his buddies managed to run this thing deep into the 8s. In fact, his best drag strip pass to date is a 8.72 at 152mph. Again, kids. That is with the power being provided by a blown, 50-year old four cylinder Pontiac engine! At the drags he runs about a 4.11 gear in the quick change rear end but at the salt a 2.26 ratio is what he uses for maximum top end charge. What is that max top end charge? So far Rapid Fire has gone 195.2 mph on the salt. Roger’s goal is 200. He runs in time only. He is there, like so many others at Bonneville to prove a point only to himself and the others that believe in him. “I have always thought about this car as more about doing than winning,” Roger said. “Winning is great and all but you just have to go do it.” Those are sage words from a guy who is humble and economical with his language. How do we know he is humble? When we asked him about updating the roll cage for the car when it became a quarter mile drag race qualified hot rod he told us that he bought a tubing bender, made up his tubes tacked them in place and had a pro finish it. When he needed a custom sheet metal intake made for the motor, he made a cardboard template that was to complete he could have run the engine off of it…if it wasn’t cardboard and shipped it to Hogan’s. He has to polish the car almost weekly because the aluminum the body is made of it so soft it gets dull quickly. Roger Manson is awesome and his car is a reflection of the guy behind it.
WE’RE GOING TO CONTINUE AND TELL YOU THE REST OF THE STORY THROUGH PHOTOS AND CAPTIONS BELOW. KEEP READING AND CHECK OUT OUT PHOTOS OF RAPID FIRE ON THE BONNEVILLE SALT FLATS!
How could you not see this thing on the salt and think, “I GOTTA talk to the guy that races this!” Visually arresting, the car proved to be cooler than even we could have imagined.
What’s interesting about the car in these photos is that it has a torsion bar suspension up front and a four link out back with coil overs. This was a departure from the solid suspension the car had for years and Roger didn’t like it. He is going back to solid suspension for next year.
The first tell-tale that something interesting was happening in the engine department was when we spotted the zoomie header on one side and nothing on the other.
Our curiosity piqued with the tiny blower and seemingly odd layout. We knew this wasn’t a dedicated LSR car because it was running class only. Learning that it kicked ass at the sand drags, runs 8s in the quarter mile, and is nearly at 200mph on the great white dyno blew us away.
While the front end may resemble a Jeep somewhat, the only Jeep parts on this thing are two chunks of CJ6 frame rails. Those were there when the car was built for the sand drags as class rules demanded their presence. Now they are just along for the ride.
The quick change rear and coil overs looked cool hanging out there in the breeze at the rear of the car. As mentioned, Roger is going back to solid mounting the axle in the car for 2014. He said the ride was rough with the solid mounted axle but he felt more in control than with the four link back there.
Certainly more important on the strip than on the salt, these healthy disc brakes doa good job of hauling the car down from the 150s on the asphalt and the 190s on the salt.
We dig the digits on the rear end housing reminding everyone what ratio should be in there depending on the scenario. You wouldn’t think this would be the case but Rapid Fire is one of the only cars we saw on the salt that also competes on the drag strip. The two disciplines are different despite the fact that they both take place in a straight line.
Roger told us that the CAE quick change is an old piece, but it is trusty and is thoroughly braced up for strength.
This little logo had a lot of people wondering what was under the shiny body. When the car is all buttoned up you cannot see the motor, just the nice blower hanging out in the breeze.
See, we told you.
So the engine is certainly one of the focal points of this car and rightfully so. It is the only 4-71 blown, Hilborn alcohol injected, solid roller cammed, aluminum headed, 600hp four cylinder Pontiac engine we have ever seen. Guys like Mickey Thompson and Smokey Yunick messed with these mills back in the day but they are certainly not considered a mainstream racing engine. Roger said that he never wanted to have a belly button motor…and he doesn’t! We LOVE this engine. From the factory it made about 120hp and made it at 3,800 RPM. Roger has his making 600+ and spinning to 8,000 RPM!
The Hilborn injector on top of the blower really lets you know that this combo means business.
This single zoomie produces a sound unlike any other zoomie at Bonneville. We’re not sure how many other guys were running Pontiac fours on the salt but we know we didn’t see any!
The salt sticks to virtually everything. Roger reports that the aluminum is so soft on the car that instead of rubbing all the salt off, they basically douse the car in WD40 and let it all melt away as to prevent scratching the heck out of it.
The radiator, like the rest of the cat is neatly packaged in the body.
Roger is Canadian, living way out in the western part of the country and racing at places like Mission Raceway, Woodburn, Oregon, and Seattle. This breather isn’t Canadian though!
The Rapid fire name came about because Roger was using the name Rapid Transit moniker until it became overplayed and he decided to switch it up a bit. At 8,000 RPM that Poncho four is rapidly firing, we agree with that!
While a blunt Jeep like nose would be cool to see, we totally understand and agree with the addition of the more aero nose cone on the car. The car is not a streamliner by any means, but anything that helps cheat the air is a good move on the salt, assuming it does not lessen the driver’s ability to control the car.
Look at how clean the front suspension is. Roger’s motto is, “My race starts in the garage.” That means that prepping your stuff as best you can and making sure it is right before you head to the track is the best course of action. The amazingly well cared for state of that car showed us that Manson’s statement was not lip service. It is amazing to think that he has raced this car in various forms of motor sports since 1985.
The three coolest stickers you will find on any race car. After 2014, it will be four.
The driver’s area is spartan. It contains a tach and a couple of gauges, a basic seat and the belts/restraints that keep Manson in the car in case of emergency. Like its owner, the car isn’t overly flashy or complicated. It was built to be simple and very fast.
Here’s the heart of the machine. Roger has used up 50 of these Pontiac four cylinders of the year racing. He knows them like the back of his hand. He has found their absolute limits in virtually every direction you can think of. He prefers pre-1963 blocks because they are a heavier, beefier casting. He runs stock Armasteel cranks in the engines, aluminum rods, a solid roller cam, and in these photos an o-ringed Edelbrock head. He has made all of his major performance marks with a factory Ram Air II head on the engine which he says is better for maintaining head gasket seal than the aluminum. Moving up, there is a custom built Hogan’s sheetmetal intake and the 4-71 blower. All of this makes up one bad ass, 600hp four cylinder Pontiac shaker!
Maintenance on the engine is easily accomplished with the body panels removed. Even here, with the side panel on, access is still good.
It is always kind of weird to see a blower hanging off a mill without four more intake runners under it. Weird in the cool kind of way in this case.
Roger’s 2013 Speedweek was cut short when this happened. Long story short the engine had suffered a high speed lean backfire on the run before this happened, which Roger believes caused some trauma to the connecting rod. On the next pass at the two mile mark…BOOM. The rod broke, blasted this picture window in the block and then the piston and crank counterweight ran into each other like elevendy hundred times, destroying ’em both. Not to worry. Roger has 5-6 early blocks prepped and ready to go. 200mph will be his!
A convenient way to check oil level, but not really what anyone wants to see. This was the 50th Pontiac four cylinder that has died with its boots on in Roger’s care. As he said, “The good thing is that I picked an engine no one wants so I can still get them cheap.” The engine is unique in that he runs a very long (almost as long as a Hemi) connecting rod in it. Those rods are aluminum pieces from Venolia and his pistons are custom made Ross units. The cam is a big (.730 lift!) solid roller that was custom ground for him by Don Howard. He runs a rev kit to pick up some RPM but also to hold onto the lifters in the event of an engine failure. Good solid lifters are not cheap so we get that totally.
Aluminum and cast iron pixie dust! Coming soon to a salt flats near you!
The whole setup is very neat and tidy. Roger pays a lot of attention to detail and the more you look at the car the more you realize how clean and well laid out it is.
This flipping rules.
Note the aluminum head here. Roger runs 25 psi of boost on the drag strip and can only get about 16 out of the blower on the salt due to altitude and other factors. He is spinning the blower 16% over.
While the Edelbrock aluminum head is a good performer, Roger said that his old stand by which is a Pontiac Ram Air II iron head will be heading back on the engine because it is more beefy and holds head gasket seal better under boost than the aluminum piece.
The Hogan’s intake has us drooling. The welding on it is art.
It is cool when the only stuff you really have to worry about driving with a belt is a fuel pump and a blower. That’s living right.
That swiss cheese looking plate it there to help support the weight of the blower so that the intake manifold is not carrying it all.
A legit, old school hot rodder, Roger is a member of the Injectors car club. We’re thinking that he’s got the fastest piece in the club.
Roger told us that he was attracted to Bonneville because he sees it as the ultimate acid test. “You can get away with a lot on the drag strip,” he laughed. “When you are leaning on things for the amount of time you do on the salt, you find out what your weak links are.”
Roger doesn’t know if he is stubborn or dedicated. We’re going with dedicated because he’s way too cool to be stubborn. He lists guys like Mickey Thompson as his inspiration for this car and sticking to his four banger guns and that says alot about him too. The man respects history. A couple of shots at 200 with this combo have fallen short. There are guys who have been trying to 200 in their cars for decades before doing it. Roger knows he’s not even at a point to complain yet! (Plus, he is not the complaining type). We’re super glad that Roger dragged the car into a clear area for us to shoot on the salt. He, his wife Marlene and the crew guys were all fantastic. We look forward to seeing this car again and celebrating its cresting of the two century mark on the salt. There’s daring to be different and daring to kick ass your own way. Roger Manson is going both of those at once with Rapid Fire.
This thing puts an ear to ear smile on my face that’ll take all day [ or one of McTaggert’s barf fest photos 😉 ] to wipe off .
Funny thing is … almost anything from the ‘ Salt ‘ puts a smile on my face these days seeing as how the ‘ Salt ‘ has become the last major bastion of automotive SPORT … everything else having degraded into scripted ‘ spectacle ‘
Now … if this guy’d just clean up his aero a bit [ ok … a whole lot ] all bets are he’d exceed his grandest expectations by a country mile [ or salt encrusted mile if you prefer ]
A local guy. Roger raced that Jeep lots, i’ve probably seen a hundred dragstrip passes and dozens of sand runs the few times i was at those.
I saw Roger and Marlene this weekend at the Monroe, WA. swap meet. He is doing a test and tune at Mission this friday. I hope to get video footage and get it to you.
I see he put a nose cone on the front for aero. The first time I saw it there it has a flat panel with a nifty jeep front end decaled to it.
Another great article by the BangShift guys. These kind of builds and stories keep the dream alive for the hand full of Pontiac faithful still out there. Best of luck reaching 200 MPH. You are so close, I would never bet against you. Fantastic car.
Man this thing sounds wicked when I heard it at Mission , I can only imagine how cool it would sound live at Bonneville
Love the article on the Pontiac 4 cyl 194 .. Not sure why I have the parallel interest maybe do to age and lack of commen sense, I as Brian have a front engine dragster, and allot of the same ideas including making the manifold the holds the 471 blower I would dearly love to have contact information as theses monsters are very unique. I have been at this for about a year, at the age of 76 I’m not sure why but would appreciate your guidance ?.

Yall need to come out to Gravelrama this august, and you will see some unique and very fast machines in the sand, a lot of which raced againt roger back in the day, and Rogers original Rapid Transit in its current trim.

Sorry for poor video quality. Go-pro was a no go, so had to use old mini-8? Still sounds good. Roger ran 9.36 at 146.5 on first pass and 9.06 at 146.9 second time out. Speedweek is less than 80 days.
