QUICKEST WAYS TO TURBOCHARGE YOUR CAR - 1. Switch to 91 octane or higher top-tier premium fuel, 2. Switch to iridium spark plugs - preferably Bosch, 3. Attach a "turbo" logo to the rear of your vehicle.

[@anthonyromeo193]

Awesome video. I’ve been trying to figure out how to control timing with a distributor. Planning on building a blow thru setup on a 85 gt with a edelbrock carb and victor Jr intake

[@NightWrencher]

For an 85 gt the easiest way would be to lock it out. The second way would be to lock it out and then use a TCS-1 to control it electronically if yours using a 6AL. The third way would be lock out the distributor and use a CD-1 to control it electronically if you dont have an existing ignition box. Lastly, you can unhook the vacuum advance and recurve your distributor so that it only advances 5 degrees through the mechanical advance.

[@anthonyromeo193]

Appreciate the info. There’s not a lot of helpful info I’ve found online yet. I still have stock ignition aside from msd distributor but plan on buying a 6al box so I can have a rev limiter and 2step. I like the idea of just locking timing out but I also want the car to be semi streetable cause it’ll definitely get driven to work

[@anthonyromeo193]

I don’t plan on running it on very high boost. Probably no more than 10 psi. It’ll be a very mild build just want a fun strip/street car

[@NightWrencher]

That will work. You'll be able to run a decent amount of timing under boost but you gotta be careful. Add 1 degree until it stops getting fast and then drop it by at least 2 just to play it safe.

[@kennyrmurray]

Definitely if you could show how to convert it. I have a good idea but I’d like to hear it from somebody that has successfully done it. I converted my Quick Fuel from gas to E85 and tuned it nicely. I really don’t wanna buy another carb also when I get my turbo setup

I want to say,I've been searching for a couple days now for the information that you explained in just a few minutes. Great job. I have a question. Can I use a two barrel carb? It's a reproduction, looks like an old Carter. Made by Thundermingo. It's kinda a cheap one but I have it on my truck and it works well. I needed the info about the Timing, using the lock distributor. Once again good video.

[@NightWrencher]

A 2 barrel will work fine if the fuel bowl can be pressurized through the bowl vent under boost such as the Holley 2300.

[@menoaz]

Do you set your float bowl level at bottom or middle of the sight hole?

[@NightWrencher]

Depends on what I'm doing with the car, but usually at the middle. If its a glass sight plug and just until it barely pours out if its a brass plug.

[@Bbbbad724]

What do you do about the needle and seat and the vents? Do you have 2 needle and seats per bowl?

[@NightWrencher]

Dual needle is for fuel flow. I havn't ran into a situation where 1 needle and seat is not large enough. Maybe when you get close to 1000bhp it starts to becomes an issue but for most street cars, its not an issue

[@Bbbbad724]

@@NightWrencher Gotcha, I am thinking about 800-900 hp with two VS7875s at 10-12 lbs on a 397-416. I don’t want to break the block. The SOHC 427s can do 1500 happily, but this is a 3 rib D4TE block with good iron and I have 2 PSE Aluminum crossbolt main caps for 2 and 4 drilled for priority oiling, so it would be 1.2,4,5 priority feed. I think 800-900 rwhp is plenty.

[@NightWrencher]

That should be more than enough turbo for that. There are slightly smaller turbos that will get you there faster but you're looking at around $1500 for the pair vs $600 for the pair of ebay 78/75s

[@Bbbbad724]

@@NightWrencher I ve considered a pair of GT3582s with the stock plank manifolds reversed, will that maintain a rising boost curve at 825 or so?

[@NightWrencher]

@@Bbbbad724 Theres too many factory, primarily exhaust back pressure. Most gt35 testing has been done on 5.3 and 6.0 engines which are much smaller than your engine so yours will end up producing more exhaust. Considering that there are 2 of them though, I'm sure it would be fine.

[@paullatham3411]

Highly interested. Would love to see what you’re doing with your power valve. If you’re running a power valve with e85, what are you doing with the pvcr’s. Thanks.

The PV circuit is a huge part of it. Its not just replace the PV with a different one, theres quite a few things you need to do to get it dialed in.

Sounds like I’ve got a decent amount of what’s required so there’s incentive for me to get started

@@stephen_crumley As long as the regulator can be boost refferenced, I'd say you're on the right track!

[@TheNumber146]

I'm planning on getting a '41 Oldsmobile, then doing an engine swap with a GM Vortec 4200 Inline 6, which is circa 2006-2009. Wonder if this can work on that engine, so I can keep the car purely mechanical?

[@NightWrencher]

I do not think this would be easily replicated on a 4200 because there is no carbureted intake manifold available for this engine and I am also unsure of what ignition module would be available for it since you would be eliminating the ECU.

[@Bbbbad724]

I have an aluminum fuel cell with a sump with two output -08 fittings. My pump is a Blue Holley. I would assume that I need two pumps so I can feed a like to each end of the carb, and the top of the cell has a return and a roll over valve. Do I need to add another return and regulator? Thank you! I want to used the FE iron exhaust manifolds to a pair of GT3582s at 9-10 lbs. Engine is at 9.5:1 CR. Thanks!

[@NightWrencher]

A Holley blue maxes out at 14psi of fuel. With 6psi of base pressure, the max boost that you'll be able to run is 8psi or .6 atmosphere aka 60% more power before the engine will begin to starve of fuel. doesn't matter if you're using 1 or 4 or 10 pumps. If the pumps can not support the max PSI, the engine will starve, regardless of fuel flow. With that being said, a single holley blue will get you to about 800whp. You can feed a second one into the same boost referenced regulator, like the Holley 12-865. That regulator has enough ports so that you don't have to run 2 regulators. 2 holley blue pumps are 220gph which is great if you're not trying to push more than 8lbs.

[@Bbbbad724]

@@NightWrencher Thank you, . I am not going over 800-900 hp anyway. The Galaxie can’t hook up more than that, but it is built for that. Two 16 psi Pumps should be fine as 8-9 to be safe 800 at the wheels is a handful . I appreciate it!

[@jeramiebentley4054]

I'm trying to figure out an 84 yota 22r. Not sure what mods the factory ASIN carb would need if even possible.

[@NightWrencher]

The carb would have to be able to be pressurized. For an engine like that, look into draw through turbos or try to swap in a Holley 2 barrel or a smaller holley 4 barrel

[@Bbbbad724]

How about 2 4V DPs or 2 500 Holley 2 Vs on a 2x4 FE that has the front 4 facing to the front and the rear 4 cylinders angled to the rear? It seems like fuel distribution would be better with two carbs? Thoughts?

[@NightWrencher]

I've played with that idea in my mind but 1) its not really necessary since a single carb can feed way more power underboost. 2) It wont work because both carbs needs to see not only the same air pressure but also the same air FLOW through the carb. If one carb is being hit by the air flow better than the other carb, that carb will tend to run richer and create more problems. Same situation if you were running 2 carbs with a twin turbo, if one turbo spins faster into its carb than the other, you'll have a similar issue. When even clocking the carb hat in a single carb set up a certain way can affect air direction or air flow, imagine what'll happen by splitting it up. I've seen it done, but never in a real performance application, only show cars. So far the best solution is either a single plane intake or a 1 inch spacer under the carb. The distribution is close enough that it wont hurt anything but I would still check your plugs

[@Bbbbad724]

[@FenrirTechniq]

@nightwrencher do you have a video or diagram of creating a "boost box" for the carb? Not new to turbocharging I just cannot find clear instructions on how to create this. Is it literally just jetting up and putting the carb in a sealed box? This is for a small engine motorcycle

[@NightWrencher]

Yes, thats basically it. The hard part is getting it to seal because the fuel lines have to go through the box somehow. Its not a very efficent system but it does work

[@FenrirTechniq]

Appreciate that input, I don't see why you couldn't hook a signal line up to one of the bowl vents to allow venturi/vacuum and still pressurize the bowl when in boost. Haven't found any info confirming that approach though.

[@NightWrencher]

@CygnusHomes thats not possible because if the boosters see boost pressure, it will try to find the path of least resistance and then try to back flow back into the fuel bowls. Thats exactly why fuel pressure has to increase 1lb per psi of boost. But if you didnt also pressurize the bowls, the fuel and air would just shoot out of the vent instead

[@juanp2138]

How much fuel pressure would I need for 10 pounds of boost

16psi minimum at full boost. 6 psi at idle.

[@jrsgarage3244]

What why not just use a draw through design what's the disadvantage of draw through carburetor ❓🚩 does draw through make less power ❓

[@NightWrencher]

I should make a video on this but basically. A draw through set up acts like a big engine and needs a lot of carburetor to get it going. Air temps are higher too. On a blow through, the air is pressurized before going into the carb which means you can make more power with smaller carbs. It also drives better on the street and air temps are colder.

[@timsimons8946]

Surprised so many people don’t understand a little more about how fuel line size works, I’ll be honest I don’t know hardly shiz about turbo carb specs.

[@NightWrencher]

Its only exclusive to carbed applications. The more powerful the fuel pump, the bigger the return line has to be in order to bypass enough fuel to keep the fuel pressure down. Not the case for EFI

[@NightWrencher]

I'll tell you what I tell everyone, if you're not running at LEAST 10psi, its not worth it to go turbo. If you have a good working NA motor with headers and freeflowing exhaust, you're going to lose power by simply installing the turbo. On my Charger at 5psi with an optimized tune, the engine only gained 30 horsepower to the rear wheels over my optimized NA setup. 30 horsepower for $2000 is not a good trade.
