Gonna take a stock 250 4.10 gears 3 speed
Change to a Clifford intake Holley 600 dp Spa t4 exhaust manifold Turbonetics based 60 series derivative Small inter cooler Water meth inject Drop in hei distrib Wide band a/f guage Boost based fuel pump and rear mounted fuel cell 700 r4 automatic
Most of the big pieces are on the way or will be soon any help insight or comments are appreciated.

Great conversation with tlowe tonight......... This build inspired by the snowman Yeah, snownmans builds are inspiring. Just my opinions, turbos like a tall gear, numerically lower numbers.(rear axle) 410's & a 3.06 first gear, turbo is not going to boost much @ all in first gear & by the time you see boost, it will be in 2nd gear. I like the Offy intake for a 250 street engine, unless you are going w/a higher stall torque converter. Better low end response day to day driving. The Clifford intake runners are huge & there goes your port velocity, which means, it will be sluggish down low. I have used both intakes w/a multitude of carbs, 350 cfm, small & large dual jet carbs 2 bbls 400 cfm to the large thermalquads, bog city 4 bbls, Overall day to day driving, the offy intake is hard to beat, meaning, off idle, cruise, part throttle, wide open throttle, you know daily driving type of situations,, Now , unless you install 3 sidedraft Clifford intake & Webber's that would be the ultimate as far as carbs are concerned, but complicated when blowing through like I did with this Blower. You have a truck, you have the room for a large intercooler. Intercoolers & pipeing are cheap on Ebay, no reason not to get a larger intercooler. A larger one is just going to cool the intake charge more, not so much w/a small one. Once you get it up & running, tune it , tune it, tune it, then you can increase the boost. Boost is addictive, you have to control the urges to boost it high. I would recommend @ least a MSD BTM box. I use the J&S safegaurd., it can detect detonation & pull timing. http://www.jandssafeguard.com/NewUniversal/UniversalVersion.htmlThese are just my opinions, take it or leave it. Good luck w/your build. MBHD

Yes my Dailey driver makes 55 psi........and the motor was built for a 100psi but it's a diesel Msd and a ca emissions gm dist 4.10s I can add the stall, the convertor is not bought........but with 275 55r20s the effective rear ratio is much less than 4.10. Got a whopping $232 in the Clifford and the holley .......gonna have to work. Intercoooler on the way. Spa exhaust manifold on the way Thanks for your help. Ill post a picture when I remember how to host one. [img]http:// [/img]

Nice truck! Pretty tall tires, about 31" or so?
The Clifford will work, not a biggie.

After a bit of reading the flexp Ate to starter housing engagement seems to be common ........gonna have to clearance the housing a bit. Of course we dit have about 10 similar versions on the parts counter at once......lol

Good way to do it. Get all the parts and assemble it to mock up. It would be nice is you could mock up the down pipe to, but sometimes it needs to be in the chassis.

Exhaust the possibilities A nice 3" mandrel bent downpipe would be nice w/3" all the rest of the way.
Turbos do not need back pressure, (don't let anyone make you think they do need back pressure) so a straight through muffler design would be good.

I think a diamond eye for a dodge is the approximate shape ........and a flow master 40 series exhaust..........I would rather hear the whistle and not the roar.. Ordered a msd btm and a devils on water injection .

Ok I have a question of timing.............electronic distributer no vacuumed advance.....set the timing to .....x? Maximum then retard with msd as boost rises?.....I wonder what the initial amount of overall timing I should try.

I believe Flowmaster mufflers are bad for a turbocharged engine. Gives problems with getting boost. http://www.theturboforums.com/threads/339072-Why-Flowmaster-and-Turbo-dont-mixUnless you are not concerned & don't mind leaving HP on the table, that choice is up to you. I run a straight through design on my truck & is quiet when cruising around & idle, but when you step on it, it can be loud for some, but not as loud as a straight pipe exhaust w/no muffler. Running no muffler = That means ticket time from the PO, PO, 5o, cops, if that is a concern? IMO, it is too loud & is raspy w/no muffler. Not too loud but sounds like a loud pick-up truck. https://www.youtube.com/watch?v=cTS0smggZnEhttps://www.youtube.com/watch?v=lQneJEltTxkFor the price, Devils own systems work OK. I use Alky control system, rated to use 100% methanol. Timing, you are not concerned about mileage? Why not use the vacuum advance? Every engine is a bit different, but best to dyno tune to see where max power is. 32-36 degrees range. *Note no boost* You can run in the 40+ degrees while cruising, but you would need your vacuum can hooked up. When you get engine knock, you can see on a dyno when the power drops off, you would then add more retard on your MSD box. Again, hard to say where to set your max timing to initially. But, depending on how much boost, what octane gas you intend to use, your manifold air temps, & other factors. What boost level do you think you are going to? What octane gas? You are going to install your intercooler right away? Start off @ low boost settings,2-4 PSI, work your way up. I would say start off with 12 degrees total timing & work your way up, but,,,, need to answer my other Q's first, before I can think of more appropriate settings to start off with. MBHD

Limit to 10 psi 92 pump gas Intercooler yes
Is not vacuum a mute point under boost ?.......or does the can handle that
What brand flow thru........I have compounded twins on my diesel and 5 inch straight pipe and it's relatively quiet...... Second turbo really Takes a bite out of the sound

Is not vacuum a mute point under boost ?.......or does the can handle that. Yep, w/boost, you will not get the vacuum advance working, are you always going to be in boost? When not in boost & just cruising around, your vacuum canister will advance your timing, giving you better mileage, when getting into boost, it will go back to your base timing, & your MSD will takeover the timing retard. It (the vacuum canister)can handle 10 PSI. When decelerating, you can get 24 " of vacuum, the diaphragm can handle 24" . So in theory, it should handle 24 psi of boost pressure.
What brand flow thru........I have compounded twins on my diesel and 5 inch straight pipe and it's relatively quiet...... Second turbo really Takes a bite out of the sound Take your pick on what brand. I recently purchased a QTP muffler. It looks like a quality muffler IMO. http://www.ebay.com/itm/Quick-Time-Perfo...d36deed&vxp=mtr
I have not tried it but on my Camaro,, but,, I am not too worried about being quiet.
In general, a straight through type muffler, metal packing is better(over fiberglass type), & fit as long a muffler as you possibly can to be quieter.
On my truck, I have a Gibson type long round straight through design w/louvers design. going from memory, it's approx 30-34" long.
The ones w/louvers inside will be the quieter ones over the perforated hole ones.

Timing
Here is what I like to do.
SET timing around 10 degrees While idling 20-25(where vacuum can helps) Cruising 40-48(also with vacuum can) Under load (naturally asp) 34-36 Under boost (subtract 1 degree per PSI)This good for lower amounts of boost , like 5-8 lbs. It depends a bunch on your fuel , cam and compression.
I have no muffler on the 65 ELCO with turbo 292. I like the sound it makes. Not excitingly loud. Used 3" pipe all the way. The down pipe was configured from old Ford powerstroke downpipes to get nice mandrel bends. Throw aways at the exhaust shops from guy's converting to larger downpipes.
