Question for guys who actually have the the Roush Kit

After porting

One of their other pictures from the link above shows a gain of 74whp and 74wtq on a car with the 3.0 (stock) pulley....
So again....are we all crazy for not immediately shipping over our units for porting?

This is what Kong shows after porting btw. And they are cheaper.

I would expect the curved profile from Jokerz to perform best.

It sounds like you are talking out of your butt.
Are you an engineer? Do you have qualifications that would back up your assessment here? Also, what isn't curved about the Kong porting? Kong clearly took away more material and left behind a more polished surface....is that not desirable?

Seems to me the Roush is not that great of an SC. I've only read a few pages here, and this is what It seems like to me.

I'm an engineer with a physics degree.

It's a great kit. Just old tech. The latest and greatest PDs relocated their intercooling to the top which is far better for supporting big power builds.

That's basically what I'm trying to say. We're flogging a dead horse. Many of us have an affinity to our S550s and Roush. From what I've seen Whipple is a superior product . I wouldn't install either in my Mach 1.

run both models through CONVERGE and see

This is certainly not what you basically said. This entire thread is for people that own the supercharger and are looking for assistance with their builds, installs, etc... or are trying to help others in their quest for knowledge and understanding of the supercharged car and the associated products. This is most certainly not a "dead horse" as the supercharger is still on my car...and everyone's car that owns one....this isn't a discussion about "what blower should I get?" Or "which blower is better?".

And in the middle of our discussion about porting the supercharger you say this:

"Seems to me the Roush is not that great of an SC. I've only read a few pages here, and this is what It seems like to me."

You just come on here and talk shit for no reason. Cool, you think it's not that great and acknowledge that YOU DIDN'T READ ANYTHING ON HERE of the almost 900 pages and have nothing good to contribute.

Then you say this:

"From what I've seen Whipple is a superior product . I wouldn't install either in my Mach 1"

AND YOU DON'T EVEN OWN ONE. So don't post! Think this in your head and move on! Be a considerate adult. If you have questions about superchargers go make you own thread. Do you think you were helpful by telling us that Whipple is superior in 2025? Do you think I am just going to pull my Roush 2650 off of my car and put a Whipple on because I had no idea and money is no object? I can't imagine anybody being this dumb and the only other option is your comments have malicious intent. Either way I don't ever want to see your posts on this forum.

The porting issue and question that just came up is valid, to me at least. If the gains really are that significant then I also wonder why they aren’t more popular.

…From what I've seen Whipple is a superior product . I wouldn't install either in my Mach 1.

I own one of each. Each has pros and cons and I’d say each does something better than everyone else. The Roush calibration is the “best” I’ve found and the closest to oem level that you can get in the aftermarket. The belt drive also has significant advantages, such as lower crank stress, a fluid damper, and retention of cooling in the case of a belt failure. Yes they left some power on the table in the tb, inlet geometry, and intercooler. However, when @Autopart101 made well over 900 with a ported blower and modest pulley upgrade, it really made it a contender in my mind. FWIW the intercooler is much less of a factor when running e85.

By the way I think both jokerz and kong missed an opportunity by not drilling an air passage right above the bypass valve.

I don't want a Whipple or a Roush. Put an S650 Whipped against a similarly set up S550, go for pinks, and the S650 will has another car to play with.

I have the following mods associated with the Roush P2 for 3rd Gen Coyote:

Boundary OPG & CS
Fore Lvl 2 e85 fuel system
Stainless W. LTH
Borla Switchfire
Griptech 2.8 Pulley
FI Interchiller Stage 2

My car made 803 rwhp and 760 torque. I have run my car in 90+ weather and have NEVER pulled any timing at anytime whatsoever since installing all these mods...even after back to back pulls at WOT...

I would run my car against any other s550 with any blower...

The Roush 2650 for 3rd Gen Coyote is the "black sheep" of the s550 world for sure. The most hated blower maybe in all of Mustang history.

Nevertheless, if you mod these car correctly, they make great power and are a good blower overall.

$3,000 interchiller is a hell of a "fix"
