[@buildingracingvideos4714]

A lot of people will call it dated, but when set up right draw through carbs work really well and fuel distribution isn't an issue. You do need quite a bit more CFM's with draw through over blow through. I will admit I only have experience with this on VW's so v8' could have issues with it I don't know about.

[@pizzandoughnutspage7817]

I really do believe that blow-thru carburetors have there place, no matter how much people are afraid to change a jet or power valve or read a spark plug. EFI has basically only been around since the mid-eighties and is not that much different than carbs. There are simple parameters to follow as well certain values given for each sensor, someone commented that if your not going to tune an efi system then you should run a carb? A un-tuned blow-thru carb will be just as bad, either system will melt a piston or a turbine housing just as fast. One system is not greater than the other, it depends on you and what effort you put into it.

[@jimcrawford4360]

Great video again. A couple questions that I may have missed. 1. What octane fuel did you use 2. What timing/ or can you show the timing map 3. What Air/fuel ratio did you try to maintain. Thanks for the great videos 4. Why did stop at 6k?

[@88silvergt]

I love what you do. On builds like this it would be awesome to see the temps and a/f of all 8 cylinders individually to see how well the intake and the carb do for distribution. Would also be cool to see the temps to see how much the carb is helping cool the charge air. Then add a Intercooler to check all the same items and see just how much is left on the table with a particular fuel if you stay non-Intercooled. Keep up the great work and was great to meet you at LS Fest!

[@lowrangeinnovascotia2930]

Distribution is different because the primary pipes on the headers are all the same as opposed to tuned to each cyl. To a lesser extent, the intake runners are different but not necessarily correct for each cyl. In other words, by changing dis or length of the primary tube, you could tune the cyl to be all the same.

[@soocrispy89]

I'm running a draw through turbo set up on a 70's sbc 305 with slight head work and a heavy cam run on propane. 10psi boost and the motor loves it. No dyno yet but I'd say it pushed the motor well over 375hp from around 160.

I almost went this way with my 5.0 coyote but there are no good single plane intakes out there for the Coyote. Holley makes what is basically an inexpensive sheet metal EFI intake with a carb flange mounted on top but it's thin, pron to cracking under boost, and far from ideal with carb. The closest I've found is a carbed cast aluminum manifold for a 5.4 which requires modification for use with the 5.0 but it can work. So, instead, I'm just going to go with the 2018 Mustang intake manifold and a Holley HP EFI system.

Love the great variety Richard , thanks . Here’s my two cents . I have a twin Borg Warner 555 BBC with too small air to air intercooler on 335AFR heads ,ported victor junior as that’s what fits under my flat truck hood , big hydraulic roller cam and a CSU 850 blow through carb with twin needle and seat bowls . This makes 1340 to the wheels at 6500 still climbing at twenty pounds boost , has excellent street manners no hiccups and runs nines in 5000 pound truck not optimized for track as I have put street manners , ride comfort and quiet cruising first . Nothing is low budget including this carb but I have been going on short and long drives plus trips to the track for five years now barely tweaking it and changing plugs once a year just because. Kevin at CSU gives excellent after sales service and advice , however this truck has been brutal on transmissions and differentials . A previous 540 was 1000 engine hp using a ProCharger, no intercooler on a Quick fuel 750 BT but it was at the end of fuel delivery with same excellent driving manners so I love a good blow through carb .

[@DodgyBrothersEngineering]

I prefer injection, but I won't ever say that carburation doesn't have it's place. Seems to be pros and cons for each. For the last few months I have watched umpteen videos trying to learn as much as I can about manifolds. I want to CNC machine my own 2JZ manifold with a built in water to air intercooler. Long runners, short runners, big plenum, small plenum, lots of considerations. What I have semi decided on is two different length runners that are fairly long, but trying to make the runners as straight as possible. Also recently I have been thinking about trying to locate the injector much further back up the runner away from the head (possibly on the turn). So it can get some of the benefit the carburetor guys get with latent heat transfer. Probably will mull it over for a few more months yet.

[@Cowboy.underwater]

Mech engineer here: If you know your desired powerband you can figure out your ideal runner length by using the distance from the back face of your valve to the beginning of your runner divided by the speed of sound and then matched up with your valve timing events. You will probably need to catch the wave on the 4th trip trough the runners (divide the original calculated length by 4) to get something that's not too long. There are formulas and stuff on the internet if you care to look.

[@DodgyBrothersEngineering]

@@Cowboy.underwater thanks, yes I saw a formula involving 84,000. Some of it will come down to available space without hitting the inner guards, hood clearance, available intercooler cores, and not inhibiting the tappet cover so much that I can't get to the plugs. I'm currently in the middle of making CNC upgrades on my X axis, so until I have that sorted I am just going to continue to ponder. I did see something similar based on a factory manifold, but it blocks the plugs by the looks of things. kzbin.info/www/bejne/mKHMeIBoaJKFbsk

Regardless of carb or efi distribution is never going to be perfect you have to get really picky with your tuning if you want every cylinder to fire extremely efficient.

@@hereinmissoula11 I think Richard's test of 'every cam is a turbo cam' covers this question. If the overlap allows more fuel air to escape into the exhaust where it burns, then it will increase response. Some of the video's show some combinations end up with too much exhaust pressure in a ratio to intake if the turbo is too small in relation to how much air the engine will flow. Boost just moves the curve up no matter the cam lsa. Just my opinion.

I'm just poking around trying to make a decision on how to get where I want to be. I'm building a daily CJ7 (CJ7 hybrid frame for TJ suspension and drivetrain, My TJ frame literally fell apart while driving home). What I'm aiming for is swapping a v8 in while keeping it a stick shift (I have an advanced adapters AX15 trans). The tricky part is I also want to go completely mechanical. Meaning I don't want an ecu. So I'm looking to go carbed with mechanical fuel injection. I also used to own a turbo car years back so I'd like to see if I can run forced induction, preferably a turbo. I haven't decided on the engine and the easier option (because it's what everybody does) is usually not the direction I want to go. I want to build what I want. Hopefully this works out and I can find a setup that will work well together.

[@remybrouwer8700]

I have not read the 201 messages they already send and maybe this has been brought up already, but I will comment about cylinder distribution with that open plenum manifold with the carburetor you used in this test, I'm not expert ( absolutely far from it ) but I only can think is, that as the carburetor butterflies open they do so pointing to the middle of the manifold in Vee shape "V", since your closes runners to that "V" shape are your middle runners, logic points out that by traveling distance and resistance the middle cylinders will be possible filled more, ( I really don't know which cylinders were leaner/hotter or richer/colder since I was not present, the first think that I would do is install a 4 hole spacer like the guts from Engine Masters did but I will go with a 1,5" thick spacer as a minimum, I believe a 1" thick is not enough to correct enough the flow downwards, this will make the outer runners to help fill more the cylinders, but what I want to propose for you Richard to test is, to install higher rocker arm ratios on those cylinders that are leaner and see if that evens more the filling charge for all cylinders, so if you run 1.5 or 1.6 rocker ratio, try 1.7 in those leaner cylinders and see what happen, if you could do so on a Ford 302 or your least favored 289 that will be awesome, the trued it doesn't matter which engine you do the test on so far they are equal distanced/separation inlet ports, I hope you really are into it to this test if you find it valid, I think I know what the results will be but like I said I'm not expert, just a engine aficionado.

[@63turbo]

It was a interesting test but the boost curve seemed fairly bumpy for both cams... might be some "funny business" going on between the carb, intake manifold and exhaust, meaning cylinder to cylinder air flow differences. Carbs are massive blockage to flow, and it gets worse as the boost increases. Airflow imbalances also get worse particularly at part throttle when boosted... the throttle plates begin favoring certain cylinders because of the angle, and starving the others, and this causes weird pulsations in the exhaust leading to the bumpyness in the boost curve. I've seen flow bench tests were they tested all cylinders simultaneously with a throttle and manifold attached and at certain throttle positions there could be a 50% difference in airflow to individual cylinders. Also, I read an account of a guy that bothered to check how much airflow his carb was costing him... when his manifold pressure (after the carb) read 20psi, the manifold pressure before the carb was 28!! might be cool to try this same engine with EFI and four pairs of throttle bodies attached to a common plenum to see how big a deal manifolding and throttle plate angle can mess with airflow balance.

[@jeremypeavley1622]

With respect to the runner length has anyone thought about Doing a custom intake where you match volume of long runners to the shorter runners maybe by decreasing size of the runner to closely match the volume of the shorter runner. Thus in turn more or less tuning the intake to balance flow to match each cylinder

[@richardholdener1727]

it's not volume that produces the reflected wave tuning-it's length (distance traveled for the wave)

[@jeremypeavley1622]

That is true and your long runners will always have a longer wave due to distance
