Default This is talked to death, I know, but Eforce or Roush?

I just want to get people's opinions on the two. I've done a lot of research and asked Brenspeed quite a few questions (I emailed VMP also but never heard back). I have decided to go with a TVS style blower. I looked into the other styles such as a Kenne Bell, but pound for pound the TVS is better under 16lbs of boost. After that the KB starts to become more efficient than the 2.3L TVS but I won't get to those levels anytime soon.

So here are all the features I like about the two models. I just need to figure out which ones are more important to me.

Eforce stage 1 from Brenspeed

-Easier to install than the Roush (according to Brenspeed)
-110 sqin intercooler
-bypass valve for better gas mileage (this is my DD)
-slightly more lower end torque because of longer runners

Roush 560r package from Brenspeed

-gt500 TB
-52lb hr injectors (eforce comes with 41 which would need to be upgraded later -if I wanted more power)
-better intercooler pump
-lower IATs than the eforce (according to Brenspeed)
-cheaper than eforce


Eventually, years down the road, when this isn't a DD I'd like to upgrade to something like the b326 and run a ton of power. Both are capable of the power I'd like. The big plus with the Roush is there is less to upgrade down the line. With the eforce I get the bypass valve which might be nice for me since this is my DD.

Thoughts, comments?

Depends on what you want a Super charger to do for "you". If you wanting to run big power down the line I would tell you to look into a Centi or Turbo since you get way more power bang for your buck with those systems plus, they let you hook up first before dumping all the power to the ground like a root system does. Again it comes down to, "what do you want it for?"

We're running the Roush TVS with great success on UPR's 2010 GT (9.90 in the quarter mile, full weight street car) but I'm a big fan of the VMP TVS. We'll probably start carrying them soon.

I vote Roush. Not only because I have one but they put them on production car every day and they last long enough to cover the 3 year 36000 warranty. It is a proven design that I have heard very few complaints about.

I believe the designer for the Edelbrock came from and designed saleen's Supercharger. The saleen supercharger I used to have had on my 2007 had issues burning though belts and belts slipping. A belt only lasted 4 to 6 weeks.

I have had the roush on my 2012 for 1.5 years without any issues.

Best of luck.

I may have to look into that. I haven't heard of any problems with the eforce but maybe I didn't look hard enough. I've heard of belts slipping and shredding with the whiple supercharger sometimes. Has anyone else heard of problems with the eforce?

Back to something you posted in the first thread: you want to stay under 16 psi, for now.
If you're smart, you'll plan ahead for when you might (or will) want more power. If you have a blower than can deliver more power later, you wont have to upgrade to a different setup.

E-Force without any question. You forgot one thing, the E-Force also looks factory and cleaner then most SC out there.

That's easy E-force, as it is not just another cookie cutter Eaton with someone else's name stamped on it.

Does anyone have a link for the Roush install instructions for the 2005-2009 mustang? I found the eforce install instructions. I'd just like to see how they differ.

Don't most of the newer roots/tvs/ts blowers have a bypass in them now?
Oh and Whipple

I thing the new roots twin-screw super-chargers do have by-pass valves. I think when you chose your brand you need to look at past and present issues. I'm not sure but i think the centrifugal superchargers do not. When choosing which style and brand you need to look at a proven record of performance with out failure and the type of driving you plan on doing. If you use it for a daily driver and performance when you need it a twin screw style works well. Less wear on the parts when driving normal. It is just a matter of choosing which one has the least issues over time.

This factor has come to my mind and my thought process is that Roush has been putting their TVS blowers on mustangs for quite a long time. They have a proven record for performance and reliability. The eforce, while it uses the Eaton TVS rotating assembly as well but is a relatively new design compared to the Roush. Edelbrock does have a great reputation for performance and reliability though.

If you turn an E-force assembly upside down you will see essentially what looks like a Roush TVS underneath. The only real difference is the intake manifold part. I chose an E-force years ago because I realized you don't normally drive around in boost - and really 90% (or more) of the time you are actually N/A. The long runners on the E-force preserve your low end torque when not in boost by keeping charge velocity up.

My E-force has been on for nearly 70k miles, and not one bit of trouble so far. But if I was going to do a Roush, I would go to Brenspeed for it. The tunes are amazing. Only other TVS I would consider might be a VMP.
