Have any of you guys put a turbo on an old carb engine? Are there any kits out there to add fuel injection easily or i hear something about a blow by carb? any thoughts? thanks
You can run a Blow-Through system, which forces the compressed air from the turbo through the carburetor and into the engine. Or a Draw-Through, which pulls air & fuel from the carb, through the turbo, and then forces it into the engine. There are kits out there, and plenty of components to make either setup work...depending on your application that is.
pros and cons to both setups. do lots of web surfin and there are a few good books you can check out. here is a web sit you can read on. (warning) vw related http://shoptalkforums.net/viewforum.php?f=3&sid=8e78daa194804a516112e1bae68df6e3
http://www.google.com/search?q=blow...s:IE-SearchBox&ie=UTF-8&oe=UTF-8&sourceid=ie7 google search on blow thru carb mods. if youre good with carbs you could do it yourself, carb hats are readily available. What engine are you considering doing? The turbo Thunderbirds 1980's had a decent set up that will support lower cube engines, spools up quick but wont support high RPM's. Same with turbo buick.
Please do yourself a huge favor and spend some time reading this forum: http://www.theturboforums.com/smf/index.php?board=13.0 One of the best resources of blow through/draw through carb-turbo message boards on the net.
I got ahold of a turbo off an 80s trans AM, i thing the motor is a 301? and i would like to put it on a hudson straight 6 262 engine.
I don't know if it helps, or matters, but I know that turbo is a pull-through.(I used to have one, and it is a 301)
I second the turboforums for info. Also if you go draw thru, make sure its a draw thru turbo. The TA is a draw thru turbo, which would be fine if you go that route. But it wont work right if you go blow thru.
Ok thanks guys i will do some more reading, I didnt know that was a pull through turbo appreciate the heads up.
turbos are pretty simple devices but implementing them requires a bunch of planning. Compressed air is hotter. Getting it from a turbo under hood makes it even hotter. most people run an intercooler to drop the temps before they go into the motor. This requires more piping and a air to air intercooler setup. Good luck
^^ that really is the place to go. read everything... then start asking questions. i've built/run draw through, blow through and injected/intercooled turbo motors. the difference between draw through and blow through turbos (for the most part) is the seals... draw through have graphite (IIRC) seals to deal with the fuel. other than that, not much of a difference. as a warning: this stuff is addictive. my hot rod is staying naturally aspirated... but my fun daily is a 2 liter pushrod 4cyl out of the 60s that's turbod/injected/intercooled and a damn hoot. kinda hard to be "traditional" to *some* extent... but i do know my grandpa had a turbo that he was running (sorta unsuccessfully) on a flathead after WWII. good luck and have fun!
After owning a Turbo Buick, fuel injection is the only way to go. Most people that own these cars have what they call a scan master to be able to tell if its running rich or lean, which is vey important on turbo cars. Not knowing how its running, you can blow one up pretty quick. If you really want a turbo, read up on the ls motors with turbo's. Impressive numbers on hp. Car Craft and Hot Rod have done articles recently.
Dan Have you talked to Rudy Bennett in Tx? He has a turbo on his 262. He is not on Hudson forum much, but he is easy to get in touch with. PM me if you need his contact info. He is a great guy and would walk you thru an install, or get you headed in right dirrection. Don
There were books published in the '60's by a guy in Florida on turbocharging Studebakers. Studebaker Driver's Club forum may have ready response. The book detailed low-buck turbo solutions, boost-referenced fuel pumps, etc. search "blow thru" with Stude group.
The sites that have a *lot* of info on, are: http://autos.groups.yahoo.com/group/Carburetedblowers/ http://autos.groups.yahoo.com/group/drawthrusuper-turbochargers/ http://www.gatorsuperchargers.net/ Not traditional, but lots of tech info. Different approach, but it works. & it's DIY. & no EFI. Other sites, but I can't remember them all right now. HTH. Marcus...
I have done several turbo motors. My last two are my old camaro had a 350 with a draw through system, and the 404ci sbc for my 55 is a twin turbo blowtrough setup, with EFI. A blow through carb setup is easy to setup, and EFI is not needed. It does make tuning easier, but is definately not needed. If you are going to build a draw through turbo setup, you will need a a turbo designed for draw through - they will have a carbon seal on the shaft to seal it. A non draw through turbo in a a draw through application will fail pretty quick. The turbo on a 301 is a AiResearch TB03 if I remember right. Its pretty small.
