getting full spool on BW S366 at 4000rpm

Recommended Posts

I purchased a borg warner S366 turbo, I went with it since price was great and they seem to have a good rep for making good power and taking abuse well.

 

My goal is to get some nice low/mid-end power, about 550-600bhp MAX (will be stock fuel system other than injectors/pump).

 

I have a 3" exhaust (no resonator) and ARC 2 row intercooler.

And for the single setup I was thinking of a 3" downpipe and possibly a cast manifold, although I'd prefer a tubular manifold I think.

 

would this keep everything flowing nice without much lag and full spool by 4000rpm?

 

I believe it is a 66mm turbo, so trying to see what I can get out of it.

I drove a GT35R supra with 460whp and it was amazing, then I drove a 550whp supra with some T78 which didn't fully spool till like almost 5500 :/ .. felt sluggish.

 

It is a street car but I'm trying to keep it track oriented.

 

 

any input would be great, cheers!

The Cast Manifold is actually the best bet for your requirements - they promote fast spool. They are also more reliable so best of all world. If I was aiming for 500-600 I'd use one.

 

I have no direct experience of the 366 so will just say that the GT35R can be pushed hard enough to produce 550 at the fly without going extreme. And that would make for a very responsive setup.

 

A 2Row IC should be enough for all but the most extreme driving as long as it's in good condition.

Should have got the S362! insane little turbo

 

It is still brand new, and have someone wanting to buy it off me for more than I paid (I got it on a discount through someone)

so I have the flexibility of getting rid of it and getting something smaller

 

although the S362 seems to be twice as much cost?

I got my AirWerks S366 for over twice as cheap! converting over to pounds it was just £380

 

I understand there are better options out there, I'm just seeing what I could do with this turbo.

How would a cast mani hold up to some anti lag action? :) just so when I get someone riding my ass I can melt their bumper off.

 

 

I just want full spool by about 4000rpm (just like my current BPU TTC setup). Would the cast mani get me close to that? or is the S366 just too big

Cast manifolds generally can take more abuse than tubular manifolds, the choices are limited for a cast unit, the best available for the MKIV is Arnouts but they are rare ;)

 

The S366 should spool better on a cast but I would still look at a S362, if that is not an option then you could improve spool further by reducing the exhaust housing a/r, what housing do you have on it at the moment and is it twin or single scroll?

Not sure why your prices are so low?? i paid just over £1000 for the S362, and im sure the S366 was around that mark too. bullseye power borg warner. Not heard of airwerks? unless its the same but different brand

S362 with the billet wheel would be the ticket !! or boost lab equivelant.

 

I'm now using a S366 with the boost lab billet wheel. Not sure on spool or power yet....but I'm sure its gonna be good. The 366 with the stock wheel hit full boost at about 4k on a VVTi motor and the whifbitz twin wastegate manifold if i remember right and that was running 567bhp.

If you are aiming for 600bhp tops go for the Borg Warner 60mm, same price as the 66mm, they are cheap as chips these days and very good turbos.

 

If you a bit more I can do the 63mm billet Borg Warner turbo, these are about £1000 approx. this will go to about 700bhp and super fast spool up.

 

Thanks

Paul

Thanks for the replies,

 

What I have now is, to be exact: BorgWarner Airwerks S366 .91 A/R Twin Scroll (66mm wheel) . It costed me $600 US dollars.

 

Well, it looks like I'm going to to just sell it off.

 

What would be the spool difference between S362 and S360? because I'm interested in either one of these two.

Now the question is with what kind of manifold?

 

Would S360 on a tubular mani be a nice setup? or cast?

BW have larger large turbine sizing even for a small compressor like 60mm setup, so I'd still expect it to do fairly well up top.

Our tubular manifold will be on par if not better that a cast manifold for spool up. Twin wastegate and twin scroll increases spool up, tested back to back with an HKS manifold ours gained 800rpm!

 

I would go with the 60mm, it's more than up to the job.

 

I can supply a complete kit minus the turbo of needed.
