which turbo? s465 or a s366?

It is the turbine section on the s465 that helps it flow. Put that .88 on the s366 and it would probably be pretty comparable would be my guess.

I too had a silver bullet before my s465, i don't have any dyno numbers to back it up but my seat o pants meter tells me the s465 pulls way harder than the bullet did.

I never tried my SB... I sold it before I had the motor done. Wish I would have waited to try it out first, though I am happy with the way my truck runs with the 465.

the SB spooled quicker, but the s465 pulled way harder after it lit
 
man i dont know which one to go with. i appreciate all the opinions guys. now i just have to decide. i think the s366 would be sweet, then i could swap housings if i want more airflow. im just wondering how much the s366 can support. im saying if i do a ppump conversion and add more fuel, will the s366 be enough?
 
If you have a manual and never tow get a s465. I run a ED s366/73/.91 on my 02 6spd 4.10s and is a great dd and i tow some with it also and i have a stock cam. If i didnt tow i would be running a s465 with out a doubt.
 
i dont really tow much. if i do it a lawn mover or a tractor on a 16ft bumper trailer.
 
stock head, had my stock cam reground. but cant really tell u how much they did to it.
 
ok, with my mildy ported 12v head and a big stick cam my s465 lights at 1800 rpm. If you can live with the lag I would go for the s465
 
There's alot of stuff out there if it were me and ED had anything to do with any part of the charger I'd call Chris and talk to him about it and get the facts about it. I'm sure he'll be glad to help. I understand there's alot of different box/shelf charger options and some are very undesireable some are not.

If the larger s400 charger does not move as much air as the s366 does why have the slower spool associated with the s400 parts (larger shafts what have you)? Now if you plan on trying to make 800hp and want to do it with a single and plan to have work done to the charger in the future the s465 may be the way to go even if it doesn't work as well as what you would have with the the 366 charger.

Good luck
 
how is the 366 going to be for sled pulling? will it supply enough air for a ppump and 6x18s? and if not a ppump, how bout a vp with a smarty and 6x18's?
 
it would be nice to have a gated housing and a non gated housing, but then again its a little more $$.

i can guarantee an $800 s400 does not flow as mush as the 366

Do you have flow sheets of the different turbine housings?
We all know on paper the compressor wheels of the 366 will out flow the 465.

That box stock s465 will out perform the s366/74/14 on the top end.
 
man oh man this thread is just really confusing the hell out of me...what s366 are we talking....what s465?? there are several different variations of the two. I'd also like to know what flows more, spools better, hp capabilties of the two
 
haha..im getting a little confused also. the s465 is the 64x95 comp wheel, 74x83 turbine and .9 t4 a/r housing. and the s366 is basically the same a the SB. the on that i am looking at any ways. it has two housing one is a .88 nongated t4 from ED and the other is a t3 gated housing from ED.

The setup includes the .88 housing with a ED T3/T4 adapter that can be used with a ED external gate.
Also comes with a ED machined 14cm housing with a ED wastegate spring style actuator, housing has the spacer on the back to allow for more puck travel, and the puck area has been machined as well.

Currently the highest-flowing S300 unit available, with maximum compressor flow over 80 lb/min. Will service 800+HP.
* Wheel Dimensions:
Compressor: 66.1mm inducer, 91.4mm exducer, with exclusive Extended Tip Technology.
Turbine: 79.8mm inducer, 73.4mm exducer, with machined back-cut (clip) of turbine blade trailing edge, for improved turbine flow. Cast in Inconel 713, for high-temperature operation.
* Housing A/R:
Compressor: .55, with 4.0" hose-type inlet, and 3.0" hose-type discharge
Turbine: .88, with 'open' volute, featuring a 'T04-style' turbine inlet flange (3.25" x 2.75") and quick-release v-band discharge flange. Cast in ductile iron.
* This is the turbo that's simply dominating the 'T04'-frame classes, direct-fit compatibility for many popular turbochargers on the market. These units are brand-new, with no core, and are made in the U.S.A.

ALL OF THIS INFO IS FROM OVER ON THE CLASSIFIED PAGE ON THE S366.

That's the exact description that's on this website which lists a brand new S366 for $900. I don't know how much a turbine housing and ED adapter cost but to me its not worth it for a used turbo.


Also on that website is an S464 that flows a whopping 64lb/min :kick: Search If thats right, that non-ETT s464 flows way less than the ETT s364 and s366s.

I would talk to someone like ED who actually knows what these two chargers will flow and try to get some advise from them.

And if you're on the phone with them you might ask them about a K31 hybrid or an s471 as a single capable of 800hp

The 14cm housing was machined by ED. The .88 t4 is the housing that cam on the charger, that housing comes with the ED t3/t4 adapter.
