Yes it should generate less heat then a hybrid. Alot of people with hybrids tend to run crappy intercoolers that claim to be good for the whp but in reality they dont compensate for the fact that the amount of horsepower is being pushed through a stock frame. Yeah journal bearings are inferior to ball bearings but people here act like its the end of the world. This isnt a Precision 7675, the difference between a journal bearing and ball bearing on a turbo this size in terms of spool and reliability is going to be marginal.
Intercoolers help turbos run cooler?

Journal bearings last as long and spool up as fast as a
ball bearing cartridge?

No one ever said that. All that was stated was the difference on tiny turbos like this is gonna be marginal. Heat management is gonna be far more important. And yes the mrx for the money in terms of spool and performance is a turd imo.

I originally said what you are saying now....Then talked to a bunch of people bout Hybrids and BT's....I'm happy decided to go with what would allow me to grow! You will want more trust me.....who doesn't?[drinking]
I had a gtx3076 ms3. It was a great highway car where it was easy to be in the midrange ready to spool and I humiliated many V8's, but around town it just sucked. Looking back I would have gone with a gtx3071, or the equivalent of the the fiesta's hybrid turbo (BNR). It turned into a bit of a one trick pony, great at straight line speed from a roll mediocre everywhere else.

You do end up shifting more often with a too big a turbo.

If I have lots of city driving and twisty roads I would want to keep the low down torque. If I'm on the highway a lot cruising at 60-80mph I would lean towards more midrange and top end. We have lots of long straights here in DFW. The hybrids seem like a good trade off for most people.

I quoted you. So you think the difference between journal bearings and ball bearing cartridges is marginal? I’m running the MRX with 4 port with no in tank fuel pump upgrade. Spool and performance are fantastic.
I’m making 296 on a Mustang dyno btw

marginal meaning the ball bearing is still superior but its not gonna make a massive difference on this platform. Where do you hit full boost because I would guess its a fair bit further down the curve then any hybrid. Not to mention the locking nut issues with the mrx kit. There is a reason hybrids and gtx2860r are much more popular. The mrx has the spool of a 2860 and the power of a hybrid. The hybrids are also just going to be more fun on the street.

What’s the locking nut issue?
The MRX doesn’t spoil faster than the GTX 2860?
What hybrid is making 300 hp on a Mustang dyno?

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 paid $150 and there are zero problems. So what’s the problem?

So can someone explain to me what the gains and losses are between the S280 and the Whoosh Hybrid? Trying to decide between these two right now. These are both within my budget, and I'm not considering any others, but I want to make an informed decision. I'm also limited to 93 octane. Looking for better performance on a daily driver, driven mostly between 1500 ft and 5500 ft above sea level. Comments and observations appreciated!
if you are only doing pump gas go whoosh hybrid.

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.

I just dont want to lose the punchy-ness of the car, if i wanted a big turbo straight line car, I'd have bought a Focus ST. One of the things I like about my freinds VT330R car is that it feels stock, with more oomph. My other friends have an MRX kit and a GT2860R, both of those cars feel like doodoo til 4500rpm, boost happens, and then shift.
they need to change tuners, my car is pulling hard from about 3500rpms, not hybrid hard mind you full boost hits at 4100whp, which means you are around that 3500 making a good 18-20 which feels really good

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.
