Medlin Blower

[Nater99]

Notice this thing for the first time when they rolled the car out of the truck at Reading on saturday morning. Anyone know what the deal is with it?

It's a 2 hole "hat". Supposed to work much better than a 3 or 4 holer with regards to maximum air flow. Still under evaluation as none of the other Force cars are using it at this time.

he has been running that injector since the western swing. it was all over nhra today a month ago:rolleyes:

[fuelfan]

NHRA mandates the size of the opening (SQ inches) not the number of openings so anything goes as long as it doesn't exceed the square inches.

[enraeh]

It's also narrower and supposedly easier to see around, plus it is divided into right side/left side so it's easier to adjust the right bank/left bank cylinders and heads for rich or lean mixture.

Every so often someone comes up with a new design that looks odd at first, but is eventually adopted by everyone. Just like the carbon fiber 3 port injector scoop. At one point year before last only KB and Lucas TF, I think,were running those. Now every TF team except for JR Todd and some lower funded teams have them.
Todd by the way has a simialar design to Medlin's, so mabey they are now out in front of all the other TF teams.

That's what is great about this motorsport-constant technical experimenting for an advantage- that keeps it from going stagnant.

I only catch the show every now and then

It really is quite a bit narrower. Looking at it without the body on the car, It looked as though the two sides went down into motor without much change in size, especially when you consider what the standard 3 hole set up looks like. I would think that could improve airflow quite a bit.

The four hole that tony P runs is lower and easier to see around. Ashley force runs that on her car just so she can see. Basically, once everyone went to the set back blower set up to equalize pressure they went to the 3 hole, but the dragster teams went to a taller model to direct the air better to the cylinder, get over the roll cage and away from the turbulance from the driver shroud. I remember when the shroud was required in fuel after the Russell accident, people were talking about the amount of turbulence that was in the shrouded area and some were talking about actually using that air that is forced in the roll cage area to their advantage, butnobody really persued it. They are basically taking the air and reducing turbulance as it enters the blower so the blower is more efficient. I really liked that scoop they used in A fuel and it was a good idea, but that butterfly is more like a 3/8" rectangle that opens right at the blower inlet so the direction it opens acutally causes more of a vacuum affect at the end opposite the blower direction of travel.

I think what happens with all these different styles is eventually the crew chiefs figure once the butterflies are completely open, that blower is gonna suck air, regardless of the shape of the hat. Us lesser racers that run injection need to adjust the butterfly plates constantly to equal the airflow at idle. So I guess the less plates, the easier it is to adjust for idle, but the straight shot of air to the blower is what everyone is looking for. I am all for a better view for the drivers and am glad that medlen has taken over the testing duties for the team instead of John doing it himself last year.

Wonder if KB with copy this method next year in his fc, I'm sure Ray Allen knows all the details.

Only if he knows who did the carbon fiber work so they dont have to pay for r&d. Alot of people copied Bernstein over the years, remember the little aircraft or go kart front tires? It just seems KB is taking the side that its his turn to take other ideas.

You know, how did KB get a charger body? Shoe has them, but the other dodge teams are still running the stratus. How did he get right to the front of the line?

Taking this a step back in time...I remember back in the 80's when Amato came out with an aerodynamic rear wing stuck way up in the clean air and proceeded to dominate for a couple races until the other TF teams figured it out.

Fast forward to today(last year at Finals) I noticed a plastic or rubber lip fastened the trailing edge of the front wing on Brandon's car. I asked him what it was for and he was reluctant to explain it(I don't blame him). I think the purpose was to creat a tiny bit more downforce on the front end but, more importantly, to disrupt air over the cowling into the cockpit. This would cause low pressure area leading over and into the rollcage just like an airplane wing and create a high-speed high-pressure stream of air just above the roll cage leading straight into the injector opening.

My point in all this is.................can't remember.

[anotheridiot]

Dont forget there is still the Garlits mono airplane wing that nhra wont approve either. That beast will never get destroyed by a blown tire, but nhra wont approve it. I dont personally like the way it looks, but safety has always been first with Garlits ever since his accident.

But back to the hat, it doesnt seem to be enough to start dominating competition, but if its smaller and safer to see around and isnt taking any power away then all they might as well use it.

You can bet there is more to the injector than looking around it. Most drivers look over them if they can but what is on the inside and how it mates to the blower is what I would like to see. What mods to the blower go along with it?

[enraeh]

Saw a telltale flash of fire from that scoop earlier on ESPN. Also heard Mike Dunn refer to the injector scoop on JR Todd's car "not reacting fast enough" to recover from tire shake on the hit...hey guys I seriously thought this was JR's to win.

That was Larry Dixon saying there isnt the same pedal travel in the plate on JR's car. I wish I could find that article to link to about that JR style injector. The loud pedal has more travel with the more common scoop so it is a little easier to pedal and get to recover where you saw JR try to pedal, but the instant response just kept blowing off the tires. I remember it being described as a .375 aluminum rectangular plate.

The scoop is all about catching air. If there was something with the body shape in the hood that somehow directed air into the scoop or maybe something they saw in the air tunnel, I can see it making a difference. Basically I think the 4 holer that uses up more hood area is gonna catch more air than medlens model. But realistically, that blower is gonna suck air regardless once any butterfly is open. Its almost like TJ changing blowers the round he lost, more air will hurt the tune up more times than not.

I also liked when Larry said he would work for less than Mike Dunn if he doesnt get a ride next year.
