Turbo Technics S280

Only if you like your turbo falling off and don’t have $150

Yeah because having to spend 150$ just to keep the turbo on your car makes sense. Ur gonna defend that turdbo no matter what.

The MRX is in a tough spot - less top-end than the GTX 2860 Gen 2 (and possibly the same or slower spool) and slower spool than the hybrids with just a wee bit more top-end. I'll bet that the area under the torque curve is greater with a hybrid or the 2860 Gen 2 than the MRX, just at different peak torque points. The MRX made more sense before the Gen 2. @MRX330 - you know that you're gonna go with a 2860G2 on a tubular manifold in a year or so after all the fast has run out of your MRX.

Lots of guessing and opinions floating around about the MRX. On E 50 with aux the MRX has more than enough power. The powerband is not laggy down low and it pulls to redline. The lack of facts and general misunderstanding of how my setup performs is understandable since I am the only one running it. Regardless I’ll put it up performance wise against anything

No one's running that because there are far superior options for both spool and power. As soon as the more recent hybrids came out everyone that wanted better spool switched to them. As soon as the gen 2s came out everyone switched to that for more power with the same spool. With the newer options coming out there's really no reason for anyone to run one.

The stock nuts that go from the adapter to the housing backing them selves out which can cause alot of issues. Mountune is well aware of the problem yet still doesn't include the locking fasteners in the kit. They make you pay another 150$.

I've had this kit on for years without anything getting loose or backing out. It has performed flawlessly and hauls ass. I love my turd.

It's a toss up honestly you would have to drive both and see. A little more spool vs more power at the cost of a little spool.

yeah, but in terms not not having that high of a WHP goal and keeping it close to stock drive-ability it would be a winner

No one is running the MRX? You talk out of your rear end quite often. Btw do you have any firsthand experience driving a FiST with an MRX? With the 3” inlet anti surge compressor housing and 11 blade billet compressor wheel it’s basically a GTX 2554r.
If you’re going to take a shit on it at least have something to back it up

I wasn't being literal dufus, I meant they aren't nearly as popular as popular as hybrids or gtx turbo

BTW is there any actual results for the S280 yet?

I don't but I can look at dyno charts and compare it to the plenty of other turbo 4 bangers with bigger turbos. They just aren't that great for driving anywhere other then the highway or track. By gtx I mean 2860s or higher, I know what an mrx is.

You’re looking at charts and Im driving it. You know what the MRX is by reading about it. I’m driving it. I could say the Cyborg is the biggest piece of crap but I won’t because I have never experienced it. I know there’s a lot of Mountune haters but walk the walk before you talk the talk

 

[wetwea33]

The cyborg is pretty crappy for a hybrid lol i bought it new for pretty much nothing and it's preformed decently. Peak torque is a little latter then most of the hybrids. I had a supercharged gto project when I bought it which is now gone so I'm getting rid of the cyborg. If anyone wants a hybrid with a Ts wastegate for 500$ with 5k miles hmu [emoji23]. Made 296whp vdyno on e30 @ 27psi. Now on e50 and aux it peaks at 29 and holds 28.5.

if you are only doing pump gas go whoosh hybrid.

Can you tell me your reasoning? Ron at Whoosh said "The hybrid needs more boost and more octane to reach 300whp where the S280 can make the same power with a few less PSI and a little less octane." which for me sounds like the answer. I'm not going to any aux fuel and 93 octane is as good as I'm going to go. That's my parameters. 93 octane, stock fueling. Maybe down the road I'd go bigger injectors if they become available, but it would still be 93 octane. I won't mind if the entire power band moves up in the rpm range, but I don't want to loose the low down torque completely.

The torque down low is exactly why I would just go with the Whoosh Hybrid, If you are not planning on that much more down the line. You'll probably appreciated more, even though you are going to be killing tires a lot more often. At least where I live it's very humid and hot. All turbos make exactly the same power on 93oct pump gas (which is actually pretty bad). The difference maker is other fuels and add-ons like Meth

Look into the MRX. The 91 and 93 tunes I have are non aux and the car is fast. An E 30 tune would be even better.

Yes if you would like to make peak torque 2k rpm later then the stock turbo, look at the mrx. Dyno sheet right from their website.

Not sure if it makes a difference, but I live 2000 ft above sea level and most my driving is between that and 5500 ft. All else being equal which turbo would work best at altitude on 93 octane....the Whoosh hybrid or the S280? Or does it matter?

Who wants peak torque right off the bat? Roll racing in 2nd gear much lol? You’re looking at numbers and have no idea what real world useable power is or feels like. Your opinions are based on what? I wouldn’t trade my setup for anything other than a proper twin scroll with a similar powerband just for the sake of more efficient exhaust flow. Why you keep chiming in with opinions based on opinion is baffling.

I have the whoosh hybrid tuned on 91 (nothing higher is available in CO) ill be going on a dyno (dyno jet ) in a week to see what shes making then get her retuned for 91 if improvements can be made and also getting an E30 tune aswell ill post them when i have them but regardless of numbers im in love with this turbo .... also im at 6000ft elevation

That elevation is a power killer. I’d get a G25-550 and jam as much air into the intake manifold as possible. Good luck 👍

Turbos were created for airplanes ✈️ for low oxygen atmospheres. You’re going to need a bigger boat (turbo)
