TOP FUEL SECRET ( REVEALED!)

in a previous video i had asked all my subscribers and people that watch my videos what they thought this apparatus was now there were some pretty good answers on this but there was also some really far-fetched ones and some that were pretty damn funny this is the test fixture uh designed by austin coyle from john force racing what this fixture was for was the development of intake manifold and its distribution so today the secrets out of the bag now i've got permission from austin coyle and i had some design work with him on this particular fixture now the base you see there is what they dynoed the blowers themselves on and the air actually went through the blower into that box and exited out the back now this just set on top of it and we used the air going from the blower through this fixture and then just adapted this pipe out the end now what i'm going to show you here is the ports on this now the ports were replicated to be just like the intake ports on the cylinder head and then down inside it what we had was an orifice that represented um how much blower boost that we were actually running in the manifold believe me it took several times for us to come up with the right diameter of orifice to represent that each one of these orifices is operated by a solenoid it's an air solenoid with a big actuator that either allows the air to actually go in through the port or not this was the console that operated the blower dyno but also if you look here this represents each cylinder now there are three intake valves open at any particular firing of a cylinder so as you go through the firing order you're turning on three then the next three then the next three and you're doing this several times to figure out which port is actually better than the other and we do that by measuring a pressure sensor at each one of those orifices this here is the air inlet which had four different flow meters on it to measure the air coming into the blower or what the blower was actually using basically it tells you the efficiency of the blower itself now this is what it looks like here's the manifold mounted on there then the blower would set on top of the manifold which represented what it was right on the race car now the whole object to this was is to make each one of these cylinders get the same amount of air and this is what we came up with this is my actual design we called it the whale of course you look at it it kind of looks like a whale some of them called it a shark but i see no shark effect whatsoever on this but the original ones i had to make out of four different pieces of chromoly eventually force ended up copying it and c and c in it out of one piece of chromoly now there were several designs and those little fins sticking out the side the height of those really made a big difference so we'd run it and coral will say hey let's go and make this a little taller a little lower and let's see what it does but this is what we came up with these heights um it goes down inside the manifold and basically it's diverting air i knew uh when developing this anytime you take a plenum area out it hurts the manifold so i wanted to make it as thin and strong as possible now in their design of this manifold you can see how much bigger they made number five and number six ports there to try and get that air there but it really didn't do a big amount of difference until we put the whale in it when developing the whale there was actually a contest between me and one other guy at the shop i'm not going to say who it was but he had a pretty cool idea it had some like runners that looked like uh i don't know like a water slide kinda and he was trying to divert the air that way but it did take up plenum area which kind of hurt it you know this whole development of this manifold and all this innovation comes from austin coyle that guy is the leading innovator of all of this action you know coyle started out as just a line mechanic but in 66 he had this super stock plymouth and he drove and he was kind of marginal but the dealership taught him if you made a mistake you get to do it again for free so coil was very methodical and he was a perfectionist you know coil's first fuel pump flow bench was powered by a two cycle uh motorcycle engine and transmission i mean they only had 110 at their voltage at their original shop and you know it took a 220 electric motor to do it so this is what he come up with that just kind of tells you the the thought process of this guy the car that they campaigned him and two of his good friends was a shy town hustler you know in 1970 that thing set 37 track records and they were more into match racing because they were guaranteed money to show up at a racetrack where you showed up to an nha event you know you only got the big money if you won eventually they got some money and they won 1982 and 83 nha championships with frank holly driving austin coyle is one of the best innovators and guess what he's also very humble john force ended up hiring at the end of 1984 and in 1992 they brought on bernie federally now he is the yang of the yi and yang and he was also the filter between austin coyle and john force in 1990 was the first championship that uh forced one with coil and then the second championship in 1991 so they were back to back now in 1992 cruz won the championship and they were second to him but then the next 10 championship these two men won together i was very blessed to be able to work underneath coil you know he's made me the crew chief that i am today his innovations are still used today and no one has done more than he has for fuel racing he is the most winning crew chief of all time in nhra racing even more championships than this guy john force thanks for watching sure appreciate it
