Im on a tight spot at the moment so I was wondering how cheeky would it be to run the 38mm tial with the new s366? Im gonna be running around low boost to run my engine in. What do you guys think asking for trouble or can i get away with it for now?

thanks

That's a good question. I'm wondering the same thing, but i'm running the S256 instead of the S366.

Would def not reccomend it. First of all, what manifold will you be running? Is this s366 going to have a divided or undivided housing? I'm assuming since your only talking about one wastegate that it is an undivided housing. Anyways if thats the case I would not even try to run a 38mm especially on low boost. You'll need a 44mm or 60mm to have full boost control over that turbo (especially on low boost levels). That turbo is good for 650-800whp

Im runing a ramhorn manifold. The turbo is T3 flanges undivided .83AR s366. Ran the same setup with a GT30r with no creeping issues and solid boost. I know its only a GT30 and the s366 is diff ballgame but I really want to run the car badly

800whp from the s366???

Schister66

I dont think its good for 800whp. The S372 is good for that kind of power, but the S366 is still a big turbo that will make upwards of 650whp.

T3 flanged comes in .70A/R .76A/R and .85A/R, not .83A/R. That's only in T4.

If you're running a lot of boost, that's fine, since you don't want to bleed much pressure off of it anyway. If it is for a street car, however, no.. You need something a bit larger, say a 41m or 44mm wastegate.

800whp, no. Not from a T3 S366. You can get into the high 660whp-680whp, but you gotta go over 32psi to do that.

i must be thinking of a s366 with the ETT. I talked to turbodano and he said the t3 362ett flows about 68lbs/min and is good for 680whp and that hes pushed it to 720whp. So i just assumed the 366 being the ett (which is guess it isnt) being able to flow 80lbs/min and make around 800whp maxing it out.

This IS ett bullseye turbo. It is a .85AR my mistake. Oh man what if I was to run 20psi on this turbo with the 38mm on street?

SpoolnG2

If I were you i'd do it right and atleast get a 44mm

DC-2uned

Yeah I would run atleast a 44mm at those power levels for the better anti-boost creep and overall response.

Shodan, what kind of whp is the s366xl capable of?

karmadhi

One thing that striked me is that there seems to be alot of shaft play with turbo. I thought it might be due to the bigger bearings used and the fact that its not ball bearing?

Maybe not 800 but over 700 as i have done it so far. right at the 148mph mark on my trap speeds in the 1/4 spinning all 4 gears. the 366 is a beast. especially for a t3

SpoolnG2

Exactly how much over 700 are you making, and at what psi? Thats awesome man...

hahaha about 4hp more. and that was right at 30psi. i have a very well built efficient motor with an AIR/endyne carbon intake manifold, a very nice set of skunk2 cams, and some well thought out headwork. its just a very efficient motor

To get these numbers, you're going to hit a wall from your setup because in order to get those 720whp numbers, you're over 32+psi. Unless your management can support that pressure reading (not the engine, that's different), then fine. But it could be a limiting factor.

Turbodano is right about its potential, but I guess I've always been a bit more conservative and realistic, and not worry about a dyno number. Every engine and tuning "style" is different. I'd rather be conservative, with repeatable results on a normal basis, than just wrong.

Every turbo has "shaft" play that is a journal bearing. These larger turbos use Large shafts with Large exhaust wheels, so the balance must be dead on at over 160Krpms. Don't worry about it. Welcome to the world of the big boys.

we have been working with Dan for a while now and tested several different bullseye turbos......and for what its worth, every turbo that we have tested has made as much if not more power than Dan has said it would......and i have to admit, there has been times where i had a little bit of doubt.....but sure enough, he was right.


if you build the set up properly, there is no reason not to boost it hard. these turbo's really shine once you start cranking up the pressure.


and for the guy that asked about the 366xl we made 730 before the trans broke on the dyno at about 30-32lbs. it would be an upper 700 horsepower turbo with the boost up. we made 810 with the s368, spinning the tires

DC-2uned

Thanks Turbo-charged for letting me know about the 366xl, seems bw is making an application for each whp goal between 500-900whp down to 30-40hp range (s256, 258, 362, 366, 366xl, 368, 370 and 372). Keep it up to the guys over at bullseye power and the borg warner company.

I agree, i tink for what i have right now is as good as it gets at those boost levels, but i do plan on maxxin out the 366 to see what she will do. just need to make sure i have a backup clutch as this competition clutch stage 5 isnt gonna hold much longer

Yes maxed out the S366 will make 800whp. I would not rely on it to make that on every application though. On the DSM's we have put down 750 so far and judging from the trap speeds on the Sponge he is close to 740-750ish.

I do have to admit our MD dyno is a little hard on the numbers, but i would rather have it that way, i am gonna take the car over to a buddies dynojet and see what she does there in a week.


man we are way off topic for the original poster, hahah

damn you

Was looking at the s366 comp cover vs garret, its much thinner.
I think im gonna use the 38mm and give it a shot see how it behaves as my bank says NO to a 44mm

go for it dude, give it a shot, we never learned anything new by NOT tryin things out ya know. just give some feedback on it when youre done so others will know.

on my manifold the wg is taken off the collector, like a Y join. I had it on the GT30r runing low boost never ever spiked, this leads me to believe I might get away for now, hope so. Will let you guys know.

karmadhi

been running the s366 on the 38mm tial, ramhorn manifold self made, holding 10psi all the way through the rev range no problem.

pics please...just curious how the placement of the gate is. Thanks for the update, thats awesome.
