you have some sick whips
Your Great! I want to to Boost my Foxbody Small block Carb V8... But, I'm a noobie. So much Info in Your Videos. Thanks!!
Did you end up doing it?
Dear Budget Boosting.
I just want to clarify - The biggest factor on compressed air heat up is the act of compression itself: from ideal gas law pV=nRT => T=pV/nR, nR is constant (number of moles times gas constant) so T~pV, as we are not changing the volume any rise in pressure must bring a rise in temperature (and in real life it's more complicated than this). Convection might play a role but a very small one. ;-)
akkudakkupl Nice write up. This particular engine is quite difficult to keep intake temperatures cool since the intake is right above the exhaust every trick I can do to keep inlet temperatures down helps. I also wrapped the exhaust and turbine section with heat insulation wrap to help but convection does overrule after the engine has operated 30 minutes or more. The large intercooler helps some but I will come up with more ideas in the future to separate the temperatures better from the intake above exhaust manifold system. I will be getting a custom twin turbo header to run twin T04e turbochargers on this car and this design leaves more room between intake and exhaust manifolds so it will make more room for heat shielding techniques to combat the heat rise that evaporates a lot of my fuel mixture when engine has been running for 30 min or more. Thanks for watching and inputs and comments are always welcome.
Don’t need the intercooler with a blow thru . But you put one on and sometimes the mixture ends up hotter
What about positioning or clocking the intake side on the turbo? I heard it has to be in a certain spot or else you won’t get proper oil circulation
Awesome vid! great info, now I have a better understanding on blow through turbo charging, my concern is on my 2.3 n/a ford engine, I was wondering if you need to attach the turbo to the intake manifold where the carb is or you can place it on where the exhaust manifold is, like in the efi svo engines..???
Arturo Venegas I would do it just like the SVO, they were quite fast in late 84 when Ford put them out. That is a perfect example to follow. Let me know how it goes.
Nice and clear.
Badtz Maru Thank you, they are improving as we make more of them.
Does you pcv system need anything special if you're using a oil catch can inline?
Hi Matt, absolutely love your channel. Cant believe i stumbled across it after spending ages thinking about what to do with my Datsun 280c. now i have decided to turbo it! and finding your channel which shows exactly how to boost an l28 carb is amazing. i am very grateful for all this valuable information. I am now starting to collect the required equipment to start this job, I'm having trouble locating an l28 turbo manifold. we didn't get turbo l28s delivered to Australia that i know of so finding one locally is proving very difficult. do you have any ideas where else i could look?
Matty Greig The R30 Skylines from around 1981 to 1984 had L20ET inline six engines which were imported to Australia, the exhaust manifolds do bolt right up. The majority of external engine parts are interchangeable between L20, L24, L26 and L28 engines. The 80's Nissan Laural and Leopards were also imported by some there and they had L20ET or L28ET engines in them. Since cars over 25 years old are easy to import, you can find them. Many wrecking yards in Japan and the U.S. have 280zx turbo cars from 1980 to 1983 and their stock exhaust manifolds will mount practically any T3 turbocharger, the only limit is the distance between intake and exhaust manifolds. Yahoo auctions Japan and Ebay are great sources to get L28ET turbo exhaust manifolds. Sometimes you can get lucky and score old HKS or Trust turbo headers for L28 engines. Let me know how your search goes.
I have a 93 5.7 Chevy with old tbi do I use a carb hat?
Can you find out how to turbocharged a totary engine with weber carb
hey Matt cool as always.nice video explaining more in details the blown thru setup good info.I will be doing a draw thru setup in the future and on this video you spoke about a fuel pressure regulator. do you think I will need a pressure regulator on a draw thru system?
f rod A boost sensing fuel pressure regulator will be beneficial due to raising fuel pressure with turbo boost pressure to help enough fuel is available to reduce lean conditions.
Budget Boosting my datsun have a mechanical fuel pump do I need to upgrade to a electric fuel pump
f rod If your fuel pump keeps up with the fuel demand of the carburetor, electric pump is not necessary. Having an electric pump by the tank and still retaining the mechanical pump as a back up would be best. Electric pump ever goes out, still have the mechanical one to get you back home.
Im trying to do draw through turbo on my L28. After all this is setup. Do I still need the air meter? Huge fan thanks for the videos
If you have a carburetor, that handles the fuel air mixture so no MAF is needed.
Thanks bub
Hello Budget Boosting, Thanks for great information. i have an old Volvo Engine its 72' B20 engine that belongs to 144 series.. anyway im planning to turbocharge it through the blow through system, my only concern its the engine's health. what do i have to do to keep my engine healthy and running its my daily driver and im not planning to rebuild the engine. my goals is to put a small turbo charger on it not alot of boost its only the sound that im dreaming of. thanks alot
LuckyBuket NoC your plan sounds great, run good quality oil for high mileage engines, change oil at regular intervals, run low boost and it should run pretty good. Good run in engines work great for turbocharging.
How do you measure RPM from ecu ?
Thanks so I'm not boosting I just want it for cold air only if I was boosting I would need a blow trough carb other wise I can just use a single plenum universal cold air intake on my 600 quick fuel carb rite?
Sounds good. Blow through is just for turbocharging or centrifugal supercharging.
nice!
Hey sir. What brand is that carby?
you are the best human ever been a while i been looking for someone to turbo a L series engine. I have a nissan L20 straight 6 and its non turbo where can i find the oil feed line to tap in too if there is none? would realy love to hear the car though, you rock...coming all the way from Trinidad&Tobago..
Nicholas Silva On ebay search for turbo oil feed and return kit, they usually run around $40.00. Sometimes TO4e turbochargers with vband flanges come with oil feed and return line kits. Can find a lot of good parts on ebay by comparing the many sellers. Competition between the sellers and we win. Find auctions with free shipping. Hopefully you can find good deals for shipping to your location. Keep boosting, Matt
Tnx friend
Nicholas Silva Anytime, Happy boosting.
Can I run my points distributor or do I need an electronic ignition system? This is one subject that doesn’t seem to be covered very much on CZcams .
I would recommend a unit light made by Mallory ignition, which is very good for the Nissans
Hi. The carb that is set up for boost has the choke milled off. Does that make your engine hard to start in cold weather?
for some reason turbo starts easier
So I have a quick fuel carb 600Will my specter single Plenum work on the carb I just got to get better cold air so i want to install a cold air intake universal will that work
The difference will be how your carb handles boost. Specific blow through carbs have provisions to raise fuel flow with boost. With a large carb hat, your carb should work fine though.
If I have 3 single barrel carbs on my 200 inline 6, could i blow through all 3 of them? Or will I have to make a 4 barrel adapt to my engine?
You could try it by finding a way to pressurize float bowls while going up on boost and having solid floats instead of the light aluminum ones. If it works good, if not, there is always the blow through carburetors. C&S specialties makes custom ones and can find new in the box ones at Summit. A 4 barrel manifold is much easier than synchronizing 3 carbs with boost.
Love the videos, but what about ignition timing?
+redneck1994 Yes ignition timing is very important.
i know this video is old but anyone know what intake manifold they use? I wanna order a 650cfm BTC but i wanna make sure i sue the correct intake thatll fit before i place my order. Thanks guys.
One of the best intake manifolds is made by Arizona Z car.com
Just compressing air heats it also!
Otherwise great videos!
akkudakkupl Comments are always welcome, after all knowledge is power and more of it is always a plus.
Also, I would love to see a car using those huge blowers that inflate bouncy castles.
Peter Kapica Yes, boost is great but high volumes of boosted air even better. I have always liked large volume blowers.
Lets see how the headgasket loves the bouncy castle blower
Peter Kapica Yes, ARP bolts, cometic head gaskets, just right fuel and boost mixture and then..... Good Fortune.
Can i get carburetor
do u have to intercool a blow thru turbo setup
You don't have to, but it increases performance and reduces the chance of detonation at higher boost levels so it's always recommended whenever possible.
Thanks for your help bud...really appreciate your help...if u would I have one more question I hope u could answer...do u think a SBC 350 would be capable of 1000hp+ on pump gas with a twin setup 60mm+...I'd hate to get into the race gas and alcohol...
+NickRC1, use extra piping to move the turbo further away from the manifold, boost difference won't be that different if you don't use a intercooler, inter coolers are basically useless in blow through turbos, the pressure difference by the time it's slammed down the carb the air is already cool enough. number two is always fit a blow off valve if running anything higher than 10 psi or you will kill your engine.
I would recommend using mechanical fuel injected carb if you know how to correctly tune and know turbo pressure, gives an edge to the induction
yes the sbc could meet your goals with pump gas. Check out Nelson Racing engines, he has small block Chevy twin turbo engines putting out that kind of power on pump and some way higher with 100+ octane fuels. They have great engine dyno videos to watch that prove it can be done. NRE does charge big money for their engines so DIY would be cost effective.
Hey Matt,
You don't have to sell me on turbos ! I am one of those unlucky souls that has a 1982 Chevy Silverado with a 6.2 and it doesn't have a turbo so as you know it has to shift down to go over a speed bump ! A year ago I had someone turn it up and he put a one tone manifold on it because it was a California truck. The manifold opened up the air inlet from an inch and a half to almost 3 inches. Man I want a turbo but, money is an issue . Fortunately turbos have come down in price which helps but finding an exhust manifold that works with my airconditioning is hard so I have been told. I love the truck and liked it better after they turned it up but I went from 23-26 mpg down to 15-18 mpg. Is there any way to win the battle with this ? I would love to know !

+cody cheney Intake and exhaust modifications to help it breathe easier would be a great help for your truck. The factory exhaust system has very heavy restrictive mufflers and catalytic converters that really congest the inner performance and economy. Summit racing sells great free flow cats if you have to run them, and thrush welded mufflers are light and very free flow to replace the heavy boat anchor stock mufflers. Summit also has some bargain intake air cleaner kits that really free up intake. I remember when I built my first turbo kit, I slowly acquired the parts and then when I had everything I needed, I started the build. One step at a time since costs of some things are quite expensive.
Hey thanks ! I have been trying to get things one at a time but manifolds are really hard to find at a reasonable price. EBay has some decent priced turbo but I don't know what size to get because my truck doesn't have a brain to set things. Oh well an inch at a time to get horsepower is worth it
I have the 700 r4 trans built ready for the horsepower and it works well. It's finding the turbo andanifold to set the turbo on is the hard part. I can't wait for some monster burnouts ! Have a good day and if you k ow a better place to find an exhaust manifold that would be greatly appreciated !

Hello i am going to be starting a turbo ford 460 s10 build could you give me some pointers as to fueling and engine management. Tips and tricks to supporting mods as well but we will be replacing cam, valves, springs, pistons, our goal currently for compression is that we want to run around 10.0:1.
im doing a extremely budgeted boost build on my chevy 350 and I have a carter AFB 750 cfm that on some websites they say it is blow through ready and some say its not so do you know any1 that has a afb that can tell me what to look for to tell if it is or not...I don't have the money to buy a new carb or most the parts to turbo my car right now but I have half the parts already like the turbo and oil cooler and oil lines and I might be able to get some used intercooler stuff but I do need some help....my goal is 5psi boost max and a cruising boost of about 1.25 psi to boost (no pun intended) fuel economy... low boost due to compression of the motor and not having the money to buy new heads
anthony perras One thing I have heard successfully done with non blow through equipped carburators is use a large airbox where the boosted air comes from the intercooler to allow the boosted air to collect in large volume for the carburetor to better ingest it. Carters are great carburetors and very reliable.
I am limited on supplies so I will look into the air box idea and thanks this carter carb was on my dads 70 chevelle on the motor he built and it ran 11.40's on the quarter mile with 10" wide street tires...pissed some big block chevy guys off when a small block chevy on street tires beats them....N/A cars im good with so this blow thro turbo thing is kind of new to me
anthony perras Outstanding, its great to see budget beat big money and big cubic inch competitors.
well I have been doing some research and I can buy a 383 making 450hp(about) and add a MSD EFI kit for 2.5k and a twin turbo kit for 1.5k to bump it into the 800hp to 900hp range and it would only cost about $8000 if I bought a crate motor $6500 if I buy a good used motor. so I'm going to run the 350 till I have the money to start the 383 build
in the end I still wont spend as much on it as I would if I bought a 572 and I would have more power...I'm going to start the search for a cheap 383 and see what happens. Thanks for the complement.
anthony perras Sounds like a fun project. Would like to see some pictures and videos of it.
Dude wy dont turn on the engine!?
Hey Matt, awesome video, you pretty much cover everything. One thing I was gonna ask is if you run some kind of ignition module or Chevy HEI distributor conversion. I know that ignition timing is pretty important to prevent pre detonation and whatnot and I just wanted to know what you use on a 280zx. I’ve been looking and it’s seems as though a lot of the ignition modules are for the 240z single pickup distributor. Thanks in advance
Try leafblowers, their cheaper
Peter Kapica Yes, I have seen that done, it works if done right and there is no lag because the leaf blowers are driven by their own engine so no lag.
yes thats good.but what if im in a retarded country and we dont have blowthrough carb .how can i transform my stock carb to put turbo.can you please make a video just for that? thanks
I have draw through turbocharging videos, they show a factory Buick Regal sport coupe turbo that used this method of turbocharging.
1st view.
TREY CARVALHO Good, thank you, feel free to view more and tell your friends.
I thought this was gonna be converting a carb to blow through. I know everything else about how it works. Good video just not for me. I know I can buy a $1000 carb but that is not budget boosting in my opinion
If you're going to explain explain the right way Have your cameraman show how you set it up Thank you For nothing
