A normal carb can be converted to blow though, no you don't need one but you do have to have a modified fuel system delivery tailored to Forced induction. Such as EFI with a ECU modified for Forced induction. You can also place a carb in a pressurized box.
Depends on the set-up you want to run. If you put the carb between the turbo and the engine then yes it needs to be a blow through. When the carb is pressurized it changes the way it works.
or you can have the turbo after the intake/carb and do a draw through setup...no mods to the carb as turbo just sucks air from carb(carb isnt pressurized) but imho blowthroygh...or efi is better route
there is blow thru and draw thru turbo systems. blow thru is the turbo blows fuel into the intake, draw thru means the turbo has to pull the fuel and air into the intake. intake of a turbo has a carb on top is draw thru, blow thru is the carb is before the intake of turbo, that means the turbo sucks the air in and then mixes with fuel.
A blow through or pressure box is the only safe way to turbocharge a carbed engine(IMHO). The old draw through systems aren't good for intercooling due to fuel drop out in the IC and the potential for leaks in the system allowing the pressurized fuel mixture to reach the underhood area. Sounds like the makings of a bomb to me. Ford tried the draw through design on the Indy Mustangs too from 1980, but it was short lived. That design also requires a unique compressor design to prevent fuel in the oil return on decel.
what about rear mount turbo? im new to all this turbo stuff but would like to learn about is so that i can maybe do that in the near future! so what is everything you need for the turbo setup ? intercooler, nre exhaust minifold if you do regular, what else and how much hp can a 32 handle? its an 88 mustang converted to carb
Joe Dirt raises a valid question. We need to know what you're looking for to answer your questions properly. I believe I have seen a blow through setup on someones pictures here on the site. ( I may be wrong ) If you're talking about the tailpipe mounted turbo, I personnally think that is a total waste of time and money, and a plumbing nightmare. To answer your question, the stock 302 block(assuming that is what you are talking about) is ok to about 500hp but that is on the ragged edge. Any detonation or pre-ignition will quickly destroy it. We used to supercharge (centrifugal mostly) quite a few Mustangs and most of the 5.0l cars averaged 400-450hp with minor fuel system and exhaust upgrades. Personnally, for what you would spend on a turbo or supercharger setup, I would do a stroker N/A 347ci crate engine.
Ive ran a few blow through's over the years and my car is currently blowing through a holley. Guess the O/P wanted to ignore my question.
sorry didn't mean to ignore your Q, but i would like to drive it on the street and some track. and how much hp will a 347 stroker kit add?
A blow through setup isnt the best for a daily driver they are touchy and the tune changes with weather and fuel blends.i do drive my car quite a bit You will need a good fuel system A stock roller 302 block will split at around 500 h/p (you can make this on a turbo alone) And a good stout n/a 347 can make the same power or more with the right suporting cast.
ok we what do you think the next thing i should do to my car to increase hp i have intake manifold 4bb holey ,exhaust and ya thats it lol
