Roush just released there Max Cooling Package for 18-21 Mustangs with the Roush 2650 Supercharger. It’s the same cooling package that comes standard on the 2020-21 Roush Stage 3’s.

Roush also released both Phase 1 & 2 kits for 2021’s.

Seems to me that the cooling kit would be a tough sell at that price. Wouldn't guys in hot climates be better off with a KC?

They would for supercharger temps but that won't help the engine coolant. For drag racers/ highway pull guys they wont get near engine overtemp conditions so a killer chiller might be a better option for cool down time, but if you are a autox guy/road course etc, Having additional engine cooling capacity could help keep oil temps down as well since its tied into that little pancake cooler on the oil filter housing. Depends on what you use it for I guess.

Definitely a bit pricey. I think this is more suited for track guys.

I had a chance to hit the track this weekend first run was in sport mode ran 10.95 @ 126 with 1.64 60ft. Then ran in dragstrip mode spun a little too much coming off the light ran 11.0 @128 1.77 60ft. This new calibration is much better than when I had the 123 bug.

Wow that's a great time for spinning and all. Now that i've sold mine I want a ride in yours.

Not worth that price!

I really don't want to sift back through hundreds of pages. My buddy asked me if Roush lowered the redline RPM for the manual shift cars in certain gears and why? What is the max RPM in each gear with the Phase 2 supercharger in the 2018+ cars? I know mine is well short of 7500 rpm in 3rd gear before I have to shift.

I believe mine is 7500. Sorry, Mine is an auto. Not sure if this is applicable.

Thanks, but I think the limitation is only on the manual shift cars.

I don't recall reading where manuals had lower redline. Are you saying that you hit the rev limiter in 3rd at a speed lower than 7500?

I think the Roush does make power at lower RPM than many other kits and does not need to rev as high but I was not aware of a change in the redline or rev limiter on manuals.

 

[m3incorp]

Yes, it will not pull through 6500 rpm in 3rd gear. I thought I had seen some YouTube dynos where the manuals would be restricted to a lower RPM redline also in certain gears.

When I got my car initially it had a 7000 limit..... VMP mentioned that they raised the limit when they tuned it...

That 7000 limit was an earlier Roush cal, wasn't it?
