carb enclosure

[Anonymous]

i have a 300-6 with a t-61 turbo,compressor wheel 61mm,compressor housing a/r.70,turbine wheel p-trim, turbine housing-a/r.63 max flow 900+cfm and using a stock head and carb enclosure but don't know what carb to use, should i use a 2v or a 4v. turbonetics say's to use a 600cfm, will the head flow with the 600cfm any help would be great,,,,, thank's

My 200 is using the holley 350cfm 2v, and doing rather well. It really all depends on what your intentions are with the motor. I could not get the holley 500cfm 2v to work on this motor, even with the same boost modifications. Others have had the same results in different forums around (turbomustangs, innovatatemotorsports). You could probably even get by with using the holley 390/450cfm mech 4v. Does 10s has had limited/poor success w/ the holley600cfm on his 250.

Like we have all seen here before, you can go with too big of a carb NA, but not boosted. Wish we could give you a definite answer, but the way we found out was by trial and error. Every motor is different.

A 450 or 600 Holley would work fine for your application.

Kirk,
Our 600DP will probably work fine with our new camshaft in our Falcon. Our troubles all seem to point to a camshaft that was way to "big" for a turbo.
Have fun!

thank's for all your reply's some say to use the 2-v and some say the 600 but with the carb enclosure everone say's that i will not have a hard time with it , i used it with a 600 on my 300-6 and a mcculoch vs57 s/c and it was great but with a turbo no one know's as for the 390cfm can't use any carb with vacuum secondary with a carb enclosure i don't how it will work with the turbo, the only problem i had was that i did not have to tune it that much ,had to open(drill) the jet's a lil bit and that was it but that was with the supercharger. thank's for your reply any help would be great,,,,,thank's

Ya a mech. secondary is the way to go. The 450 only comes that way. A 600 can have either.

Instead of enlarging the jets to enrichen the mixture for boost, use the power valve.
Drill out the PVCRs (two holes behind the PV) and get a PV that'll open right at throttle tip in. So if you're running around 12inches of vacuum during cruise, use a 10.5 or maybe a 8.5 PV.

1st thank's for all your reply's some will not do that much if they see u r a newbe, anyway i just dunn all the piping from the exhaust to the turbo and the bracket's to help hold it up. i seen a few broke just under the flange with no bracket's i think they will help out. i am waiting on my two copper flange gasket's to come in and then the intake/exhaust/turbo/manifold(all 1 unit) will be installed and then the carb, i just don't no what carb to get but i think now i will go with the 450cfm i'm not a hard core racer i just want something for the street, 6-8-10lbs of boost hell i run 4lbs in my nisson 4banger and keep up with some v8"s, also i have the enclosure that had worked great with my old supercharger(vs57) and a big fmic, what i want to know is will a fmu work with a carb, i have one on my nisson efi a 4:1 but never seen them use with a carb before.( but then again they work off of vacuum) and the power valve should i try that before anything or wait to see if what happen's 1st and a fuel pump should i keep the old fuel pump and T in the electric one in or just go with a all new electric one with a return line to the tank what do you recommend and what kind, i hope i did not sound dumm i don't know that much about turbo's and i did not know anything about supercharger's but i put and old unit from a vw that i found in a junk yard on my nisson and it still going after 2year's i just hope that this turbo work's out like my nisson i had no problem's with it at all, but then again that's where all the fun is . and again thank's for all your reply's you are the one's that make the forum's work,,,,thank's,,,, keith

Kieth,

I want to help you - and I can, but please... work on your presentation. Reading what you have written with random punctuation and no line breaks gives me a headache.

Yes, a FMU will work IF you use the carb enclosure as you describe. You should also run a purely electric fuel system if you want to make the installation as trouble-free as possible.

Take a little time while typing and try to make it more readable and I am certain you will get more results.

Paragraphs are your friend.

I myself spend too much of my free time on different forums and if I see a big long post with no breaks I will tend to skip over it unless its something of great interest.
