26GT got boost - not ESS/Whipple/Procharger *Roush 2650 Phase2 810hp*

[ZXMustang]

Some of you know, Im a tuner. And I have owned 5 now of these S650s. Building tunes and testing for the last year. I've owned, tested and tuned all the major kits except the Roush kit. So with my new 26 GT I have, I decided to try it out.

One thing to note, the roush has a bad rep from the previous gen blowers being the old Eaton Roots style. They heat soak and are generally inferior to all other PD style blowers from the last few years.

Well this newest version is based off the Magnusson 2650 rotor pack/cooling brick design. Its a TVS blower, not roots. Its far more effecient than what you would have gotten before. The case design, the cooling bricks size and placement. Its right on par with the Whipple 3.0.

The 2650 TVS blower Roush now uses is very similar to the LT4 Magnuson 2650 that everyone loves on that platform. Its known for better than stock tq down low like a PD blower, but pulls harder up top like a centrifugal blower.

And having one now on Roush's tune, I can tell you this is still the case. It has a bit more punch than the G3 ESS blower my last 2025 had, but it pulls harder than the whipple 3.0 I also had...lol. These are all seat of the pants feelings, but I seem to have found a sweet spot.

The point of getting this was to create custom tunes for it to sell like I have for all the other kits, but also have something I can enjoy as well. I dont feel the need to sell this car as quickly once I have all my tuning complete.

But for what I feel the roush tune is pretty darn good. Shifts nice, drives nice and pulls hard to basically the stock shift points. I will be putting in all my quality of life changes and also leaning it out/turning it up a bit spark wise. There are always lots that can be done over these OEM calibrations.

Here is what she looks like. Completely stock with just the kit installed.

A few follow up points. The roush team was awesome answering the phone and walking me through their software to get it flashed.

The front bumper didnt even need to come off to do this install.

With the stock airboxes and airfilters, I can hear NO WHINE from the supercharger. That sucks. Roush said I would need to take off the lids and put on some high flow filters to be able to hear it.

Roush is letting me submit the warranty paperwork and they will cover the 3/36 powertrain for the duration of the cars factory warranty since I had a real shop with certified mechanic install it. Doesnt need to be ford to do it.

@ZXMustang : Much better!

The Roushe setups are nice with the Red colour and keeping the dual TB's. Question:
1. What size TB's are included? Are they the GT500 size 92mm?
2. You can add the CF CAI tubes; those would be a nice touch.
3. I did see a YouTube video where someone compared the cooling to the Whipple. The Whipple is larger, but the Rouche has a different setup. I would wonder which would saty cooler over all.

I think also there may be some more customizability tuning? I know with the Whipple you have to use that file because of the single TB setup from Whipple. I always wondered if the other tuning is similar to that of the other companies, or would that not be the case because they keep the dual TB setup.

Looking forward to see what get done here. Congrats on the vehicle.

So, in your case, I will say:
Let the mods.....CONTINUE!

TBs are the stock ones. No change there. Yes roush sells intakes and tubes for this. Im not sure if other brands will fit, but I might try JLTs.

The 2650 has massive cooling bricks and does a nice job keeping things under control.

Yes I could tune it from scratch and I probably will. But I also want to see how roush does it. They have drivability nailed right now and in my experience less is more. And tuning many boosted set ups, I see a lot of mistakes from other tuners trying to reinvent the wheel with the calibration. You dont necessarily need to touch everything. A lot of the Ford calibration is built on the 1+1=2 logic. And when you start to change that equation via tq tables and table scales, you really can tune yourself into a corner. I see it all the time.

You can almost get away with a very stock calibration with only subtle changes to parts like spark and fueling at WOT, considering when you're not in boost you are basically driving an NA stock car.

Anyway Im going to read it out and see what they did and either improve on it like we do with the whipple cals or just write one from scratch.

Did you keep the stock exhaust/cats?

Yes but not for long. I will order some headers here shortly. Before I grenade the stock cats like I did with the ESS car.

The Roush tune can be read by HP Tuners?

I read mine out today. I havent opened it, I had to run out the door. But I did a full read on it when I got home.

This was the last variable I had if I was to install the Roush SC. Looking forward to seeing your future posts about the Roush SC.

I must say I do like the way this kit mounts up and how it looks compared to Whipple. Does it fit pretty well in there? Is the GSS kit similar in difficulty to install compared to this ? It looks like the stock airbox mounts are different or something? I would like to look into this kit but Im wanting to keep the suspension brace, plus the weight of it when compared to the GSS is it much heavier or not so much? Very nice BTW. Cheers

I didnt personally install it but my guy said there was a lot of trims/tweaks he had to do per the instructions. Smoothing something here and snipping off a tab there. But he also did not need to take off the front bumper either to install any of the front intercooler, pump or piping. So it evened out compared to say a whipple kit that would be less cutting/trimming and more just snap on, bolt on. But once dont, I think this kit looks better by far. The blower lid is sleek and it fits well under the hood. Not sure about the cross brace, but I think I heard it still fits but I dont know that for sure.
