Carburetor vs E.F.I. - Dyno Room Showdown

I want to show you guys a trick I got with the oil pump before you grenade your engine [Music] as usual things are blowing up at Nick's garage he's got his mechanics all working hard and there are tons of jobs in this candy store of a shop every intake has a story everything points to an engine that I've got here like I said we have a busy season where you got started on it we've got a few inches going I'm doing one after another and everything going so far so good today one of Nick's customers Big Al has smuggled in a little present for the Box [Music] it's a 70 ta just like Nick's real one [Music] over the years nick has collected a few trophies a lot of good friends and plenty of memories but this is no time to reminisce there's work to be done here we go 750 exactly perfect we're all the money setup 750 and we're ready to grow we're using a 94 8 sold through a venture Canada here in Canada which is a 94 game which is old-school gas station and then our clients point from the but you can do so well building all the edges an octave by 4 so do more testing with the same fuel and see how it goes the subject of today's test is this beautifully rebuilt 440 that's going into Louise W 104 by 4 truck Louis wants to run his engine with EFI for easy starts and fuel economy but nick has had a lot of luck with carburetors over the years so he wants to do a test on his dyno and see what the numbers say another day at the shop here we get this one running with their fuel injection make a compression here with the carbons that we had on before we have a few restrictions on wanting to put on the engine and then try it up your impulse power torque so really get it worked up and start doing a few tests and it's here we go there we go we're gonna read it front inside okay we're gonna do an initial cold start on the fuel injection don't forget this is something that stood on its own and dry so under you drive it the board's gonna hurt so now we're gonna do a Miss will start and see how it goes and here now we're gonna start it and stop touching the gas pedal here we go [Music] [Music] [Music] Nik keeps an eye on the gauges and lets the EFI system do its thing it's constantly monitoring all kinds of parameters and making adjustments on the fly for a while you can almost hear it thinking [Music] [Music] [Applause] [Music] [Music] we are set up like 50 rpm and that's what I want to see after it's warmed up here we go again watch Oh God eventually the 440 levels out and the EFI seems to be running smooth Nick decides to go for a test body tension and it's you what horsepower we're gonna get out of this here we go [Music] we have the cargo is always you got a one for 39 for to be in the car Peter so let's see what we got on the ejection or 29.6 with their I went to make over 30 that's it here we go for 2009 with a flight deck the same engine we been completed with Deanna Carmen so there we have it so when it comes to full throttle carpet is the way to go don't expect Nick to be pulling the carburetors out of his brothers race cars anytime soon but for his customers with cruisers there's still plenty of room for EFI people drive the cars in the weekends only sometimes when you park a car for a week with a car beater and you want to go start it a week or two weeks later you want to take it for our crews or for a drive even have to crank crank crank to foot the full bolts to get the carburetor started on a fuel injection what you do is turn the key within a few seconds by it starts another successful build it's time to get this big block off the dyno and make room for some of the many other engines in the shop [Music] now you're probably wondering what Nick was talking about earlier he's got a little tip with the oil pump that just might save your engine in many cases on but many aftermarket oil pumps on the big-block mopars you can see here this is the suction side of the strainer that sucks the oil into the pump here's the pump that's made aftermarket you see this opening it's a lot larger than the opening side of the pup here so in other words we're restricting oil volume on the pump look we'll put this like this and take a good look right in there deep inside it is the hole to the body of the whole pump is smaller than the opening on the block and we do this it's on the upper side which is right here see that we're gonna open it to about this much to match the opening here so I'm gonna have the full flow of oil working with the pump so we're gonna take a grinder and we're a much as much as best we can watch this [Music] now we're gonna match it as best we can or just about perfect watch this let's line it up again there you go let's look inside and look at this voila so here's another neat trick for mix garage taking the main oil pump body no matter who makes the oil pump any manufacture you should always take apart the pump motor on this box they're pretty like I just did just a guide and line up the hole to see if the body of the oil pump is big enough to the block in many cases the hole on your pump is a lot smaller than the hole on the block now you have all the volume with you all you need through this pump and it's a free tip for neck [Music]
