New Borg Warner S300sxe Turbos

Not necessarily, just because a charger can flow 100 lbs/min at blah blah blah pressure ratio, doesn't mean the engine can actually ingest that flow rate.



I've always wondered what mass flow rate these engines can actually consume at each fixed rpm/temp/pressure ratio. For example: stock engine 5.9 CR 3000 rpm, 150* IAT, 4.0 pressure ratio sea level what's the mass flow? Because if you keep the density fixed (pressure&temp) and rpm fixed, the engine can only ingest a finite amount of air. To get more air in you'd have to raise density (more pressure/less temperature) or change volumetric efficiency via rpm change or porting/valve train etc.


Eric was asking just about the turbo, but you do bring up a very valid point

~60-65 lbs/ min
 
Would the exhaust housing off of an older s300 variation turbo work on one of these?
 
I have a question...can you just use the cartridge and use the old compressor housings?. I have 3 66mm 73mm turbos in a triple setup and I don't think the new compressor housings would fit even if I had them milled for 2nd gen. And the secondary has a pipe welded to it for the primaries so I would have to get a new transition pipe made. I would like to update to the new s300sxe turbos.

the compressor housing is part of the design you want and are much bigger then the housing in your set-up , would make nice in the set-up and move bunch more air .

According to the Borg engineer I spoke with at Sema, most of the flow gain on the new SXE turbos came from the revised compressor housing. Obviously the new 69mm inducer helps that charger but just compare the old 66 vs the new 66, they have the same compressor wheel dimensions just the new ones are fancy FMW vs. cast yet the flow difference is amazing; 87.5 lbs per minute is a 16 to 17% gain!
 
Well I know what I'm getting next. Should make driving to work more fun.
 
I think it came form a Wade bashing thread.



But it's the easy "answer"...just go with it! LOL

Apparently you must've missed the content of the original question, otherwise your keyboard saddle and pink as$less chaps wouldve been hanging still. Lol

So since you know all, please do share your 369sxe experience........

Your kidding me right?

You put turbo on, take it out in the rain and act like it's the greatest thing since sliced bread.
Don't be mad bro, most thought the same thing about the batmo wheel when it came out.

Go do a burnout in the gravel and come back and tell us how bad it is.
 
how much longer to build boost from a stop than a 64/71/14? With an auto
 
My 63/71/13 spooled slower than my 63/68/ 83. The 69 was boostless until 1900rpm. unless really trying to spool it then it was full control of boost over 2250 rpm.

5x14s 7mm d.v. benched 215 pump. Pdi manifold. 20° minor p&p head. But the truck is a 5 speed.
 
My truck cruises around 1900 at 60. My converter is too tight - 17-1800 rpm is where it sit when I'm in 4hi with the brakes on. It's nearing end of its life anyways. Figured I'd get a 64 or one of these new 369s and finish of the old single disk and get a looser triple from dpc. Maybe 2000-2200 stall

I have 026s , 5x.016s 180 pump at 19*. Trying to sell the 351

Inside joke.

Why not a new 63/68 sxe. It is a ton of fun to street drive. Responsive torque curve. I can have full control of boost at 1800 rpm in 4th gear 1:1.
