    Default Need some info on Carbs + Turbos

    Looking for a good resource on this. I've looked before but I cant get any info on making this set up work. I have a hard time understanding how a carb can keep up with the peak and hold needs of a turbo. Any help is greatly appreciated.

    Depends on how the whole intake is set up. Draw-throughs like SU-type carbs can work and could probably provide enough fuel if properly set right, though it'd likely run very rich at idle. Would definitely require new jets. Webbers and Solex/Mikuni's would probably have less issues with being rich at idle, but the same issues with requiring new bits and baubles to work right for it, definitely cost intensive.

    The other problem with this setup is that if you use an intercooler...you're looking at maybe 3+ feet of tubing and intercooler after the turbo until you're inside the engine, the whole time the air is carrying gas with it. I've seen it before on S30 Z's but I honestly could not tell you how well it worked for them, never saw the car running, seems oddball to me, and I'm iffy on it.

    The other way is to set up a blow-through turbo system, where the system works a bit more like conventional FI, where the Carb is right before the Manifold and the gas gets added as the air is on it's way in to the engine. It has it's own set of issues too, mostly with making sure fuel gets added properly. What kind of car are we talking about, and why isn't fuel injection a possibility? Megasquirt makes a kit that'll fit anything.


    Here's a guy talking about a Turbo 510. Probably has more answers for you than I did. He doesn't use an Intercooler, by the way.

    Was just curious about how it worked. I found some other tid bits here and there. Thanks for the info though. I'll be picking up a 77 ford f100 from my grandpa over the summer. I want to make it into a street truck but the 351M is riddled with early emission controls. One of which being 8:1 compression stock. Was just exploring my options. It's pretty much a Cleveland so I have plenty routes to take. Just the 151hp is terrible lol.

    I know bro just like to tell you that you got a lot of posibilities, plus hell in a V8 you dont need more than 15PSI to achive a lot more than 300 hp.

    I think edelbrock has a blower kit made for carb'd set-ups.

    have you looked into a small sized blower vs turbo? i mean a turbo is cool and all but i think a sc is more suited for what you wanna do.

    You're right but a small blower but it just doesnt have that DIY feel that I want. In all honesty there is a very tiny chance that I will turbo this thing but it would score big points in the cool department lol. This generation of Fords are seldom seen as street trucks so it has that attraction for me. I was planning on the junkyard route/set up. Using things like shorty headers with adapter plates and a t4 on each bank from a Cummins in a junkyard. My friend eraser4g63 would help me with fab for charge pipes. I've found the dogbox for the top of the carb already it was just the fuel and spark I was worried about. Seems like I won't be able to make it very streetable without some work. I mean I could over compensate with fuel but it would run rich as hell at idle and low rpm. Also I'm still not sure how I would implement a knock sensor to control spark.

    turbos r really comin in strong with the v-8 crowd. get a blow through set up. that guy seems to really know what hes doin. they also sell blow through carbs. if you go twin just set up each side independently with wastegates too and run 7 psi per side. with a total of 14psi at entry and then run the 2 together right b4 the hard hat entry that has to be sealed on the carb and get your timming and fuel dead on. or get a big single setup and run the 2 exhausts together b4 the turbo.if you went to a fi set up you could tune with a lap top on the spot and lots of $$$$. but blow through with the right jetting in the carb is the cheaper route! take a look on youtube and type 2500hp dyno in the search bar and see what you think!

    blower vs turbo. i build turbo kits , and ive had them all. turbo supercharger, nitrious and all motor.. and its also about how much your going to drive it and everything else. yes a blower is easy to install makes great power and sounds cool.. but most blower have alot of problems producing lot of intake heat.. your typical weiand 142,177 'little huffer blowers', make lots of power and is VERY streetable. but than can go past 8psi. belt slipping, and intake tempertures of 280*granted you still can make alot of power at 6 psi with the right setup. i have a buddy who went 9s in a 4200 pound chevelle with this blower at only 6psi, with a little ol 383 stroker. 9.40 @130

    turbo is easy to drive on the street once its dialed in good. good on gas because its not alwasy in boost like blower, were you still can cruise and not be sucking down your gas, but when the time comes you can nail it and let the fun begin. and when the turbo spools the bullshit ends.lol

    pro charger very good power adder, good for daily driving but also youll spend a are and a leg to get one. and still have alittle belt slipping problems but very good on the street and strip.
    when it comes down to it. its all about what you want how much your going to drive it on the street, and how much you got to spend.. yes you can get you a nice weiand 177 blower for like 1700. and still fit under the hood. and have the cool whinning sound. a turbo is all in quility. you can peice one together and buy cheap turbos and make you a budget build but its a 50/50 chance. unless you have money to spend on your turbo.

    pro charger your going to spend around 2500- and up. me go turbo or weiand blower but thats just my 2 cents...happy hunting.
