Hello! I plan on putting a 350 in my car soon, but I want it to go really fast. I want to supercharge, or turbocharge it, thing is its a carbureted engine(car was swapped to carb. so no electronics needed for fuel injection). Should I add a super or turbo? I don't want to waste much gas, but I want to get that awesome horsepower. I need ideas!

Thanks.

 

How much horsepower are you shooting for, and how high are you planning to spin the engine?

 

Honestly, i just always wanted a charged 350, and now i have the money to do it, i don't know a ton about them, i just need suggestions, im having a mechanic do the work.

 

If your going to run cast parts, go with a supercharger. Not that a turbo won't last with cast parts, but you don't need the added headache of the heat being generated from the turbo creating higher air temps, not to mention the wastegate and oil line plumbing which can be a pita. A D1SC Procharger is the way to go, just get your hands on the right boost referenced carb, fuel pump and pay careful attention to your cam specs...

 

If you asked me Use Both. Superchargers don't work well at High RPMs and Turbos Don't Work Well at Low RPMs (Turbo Lag) so why not use Both?

 

Compression of air naturally adds heat. Turbo just is hot to begin with so some heat transfer to air charge but they all have heat.

Dont want to waste gas but want to make hp to go fast. Those dont really go together. Lol

How fast is fast? Heads cam build will be cheaper and 500 hp capable

 

Superchargers work fine at high RPM, you just need to select the right size supercharger for the application. A P1SC will run out of steam way before a D1SC will, and an D1SC will run out of steam way before an F1R will. The idea is to taylor the supercharger to the engine being used, eg; cubic inch displacement, cylinder head flow, and cam specs. Turbo's don't lag when you size them correctly...

 

Not a turbo guy.Orr won't a inter-cooler kill of the air charge heat??.

 

To a point. Depends on how big and how good a cooler you use as well as type... Air to air water to air, etc. its just that a turbo is already at 300-400 deg surface temps from being exposed to heat radiation from turbo exhaust housing. That does have some effect on the incoming air that gets compressed. Small amount of additional heat transfer heating of air charge but air is in and out very fast so hard to say how much a hot compressor housing affects air.

Intercooler is always a good idea. Low boost, can use an fmu to get fuel but 2 bar map conversion is proper way to fuel it. Most blower kits come with fmu's

 

Ok,suffering from a brainfart, whats a fmu

 

Fuel Management Unit. Runs boost pressure thru it and it increases fuel pressure a certain ratio, like 6 to 1 or whatever to increase fuel sprayed thru the injectors. Its band aid tuning at its finest say you run 5 psi, you will see 30 psi of fuel pressure increase if its 6 to 1 ratio. This is hard on the fuel pump and fuel system in general. Most injectors seem to be ok with up to 80 psi or so running through them but I have seen vids of higher pressures causing erratic spray patterns and such. Not what you want for ideal fuel control.

For lower boost pressures and lower HP levels, they do work ok. I just dont like them as much as a 2-3 bar Map sensor tune or even MAF based setups that can read that much air.

 

If your not looking to burn alot of gas, should prolly stay away from anything blow thru.
Blow thru = carburated super/turbo engines.
Alot of good basic info and tech related to blow thru at

I'm kind of stuck :\ where do i find the right turbo kits at? i'm not too sure about the ones i find?

 

You wont find any. No one makes a bolt in kit anymore. You have to fab yourself or pay a shop to do it

 

I'd get a procharger. Less plumbing

 

Turbos are cheaper if you do it yourself. Blower kits these days with intercoolers are pricey. Looks like 5-7 grand for some?

 

You would think that someone would have come up with a off the shelf header/manifold setup for twins that fit our car's by now. A Lot of us could proceed from there.

 

Well stainless works has headers that face forward but you'd have to do alot of work from there and they are pricey at 900 or so

 

I'd fabricate some headers. Like Christanz28 said surprised
There's like no company out there that already has em made.other
The stainless steel works

 

Bbs designs used to and said they were gonna make more but idk if there was enough interest in that product.

Makes me wonder how realistic the market is, as you see alot of people looking for turbo advice and and wanting headers, yet never see a finished build thread.

 

Hell I was thinking once I get some welding school finished,
I wana fab up a couple for the hell of it.

 

They are very easy to make. I made three sets using 409 steel, one for myself, and another two for local G-Body owners. I just finished a twin turbo set using cast iron exhaust manifolds w/T3 flanges, very simple to do.

 

Maybe you can.make.me some!

 

Buy yourself a flux core welder from Harbor Freight for a hundred bucks, spend an hour or two practicing with it on some spare exhaust tubing, then start putting together a plan as to how you want yours to route. It is too easy not to do it yourself, believe me...

 

Is that what you used? A harbor freight welder?
I've amways wanted one.to.make the set up but was always
Thinking no way could a harbor freight flux core welder do.what I want

 

I am using a Miller Mig Welder now, but I had a Harbor Freight Flux Core welder already, and it worked just fine. I welded a cast iron exhaust manifold with the Harbor Freight unit to prove a point to a buddy awhile back, took a sledge hammer to it when it was finished, and it held together just fine. We even had it on an outside vice, bolted a used turbo onto it, then heated up the welds with a propane torch and got that fawker hot, didn't budge. Trust me, it'll take care of what you want, it's just a little messy from the spatter...

 

Awesome! Now I can do all my own exhaust work!
Ima go buy me one now.

 

Using a lincoln flux core setup you can buy at home depot or lowes for like 450$, did all my exhaust work, turbo manifold work, subframe connectors and various other general welding tasks
