looking for a streetable "quick spooling" 500hp
 

like the tilte says my truck is a street truck, doesnt hook to a sled or pull much, aside from what i have in my sig. and 16.5 degrees of timing and a airdog, what fueling mods and charger would i need to make a quick spooling 500hp street truck? i have begun to look for a phat shaft 62 as i believe that may be the charger for my goal. I would like to stay away from spray def. and maybe twins, id rather a good soild single but i would like your guys ops:tu:

71 wheel is a pig and the housings crack. go :tu:62/68/14 IMO.

I'd have to agree...I broke 500 hp on my 24v, but it wasn't a quick spooling setup, since I was running a 64/71/14....

please explain the turbo index to me as its still a fuzzy area 62 is the what? and the rest of the numbers are? as far as i have gathered 62 seems to be what i should be looking for in a single

the common #s used are the small end of the wheels and the exhaust housing size.
SO...
62 compressor wheel /68 exhaust wheel /14 housing

my buddy built a truck and put an industrial silver 62 on it with a 12cm exhaust housing on it, It would light really quick, he was running right around 500 hp and 600 on spray, I can tell ya his egts where through the roof on a dyno or pulling a trailer but it ripped on the street he just had to watch it really close. To get a 500 hp truck to spool quick and have managable egts your best bet would be to do a good towing twin set up that uses your stock hx35 that way your spooling stays pretty close to stock but you also have that bigger turbo to move the air you need for 500 hp

Alright if I were to use my hx35 in combo with another charger what would be a good charger the hx could spool quick? Is the phat shaft 62 still good in a twin set up or could I run a slightly bigger turbo

you probably could use a 62 or any S300 platform turbo would be good you would have to do some research and talk to some guys to find out what set up will work best in what your looking for:tu:

a s300 is pretty much a hx40. id try a hx 50 and hx35

before anyone gets confused, the hx35 or s300 (in this case 62) would be the small turbo in the compounds. A BHT3B or S400 type turbo would be the big one. a set with a pair of turbos too closely matched will not yield good results. the big turbo usually flows 2-3x as much as the little one. an hx35 flows about 575cfm, a S362 flows about 900cfm, a BHT3B flows about 1200cfm, an S475 flows about 1500cfm

an s362 flows 900 cfm? sounds a little on the high side

I'm not sure 500 hp with minimal lag is possible with a single turbo unless you spray it. I might be wrong, but that's about where I am, and there's definitely some lag. I haven't seen anyone else with that much power and a single turbo present any magic bullet that gives really quick spooling.

The HE351cw makes 450hp and spools FAST. I imagine a 62/68/12 would be dang close.

ive heard of a s362 before can that be found on equipment? i can readliy find turbos off of equipment if any would be a good match. what should i look for?

also where can i find a ht3b or who makes it

s362 is common on JD and Cat engines. the trick is finding the RIGHT one. most will be a non-gated large T4 housing as these engines run at a pretty steady pace, unlike our trucks. New housings cost a few hundred. the engines will prolly be about 8-10 liters. a 12-16 liter will have the BHT3B/HT60 or Detroit60 or TV75 or HX60 or S400 you'd be looking for. don your calipers and look for a 74-80mm inducer and as close to a 26cm or 1.28 A/R as you can. Try to stay away from "odd-ball" turbos like T50 or 4LHR as they will be hard to get connecting parts (flanges/clamps/boots) and dont work as well in general. :tu:
