Looks good to me!

 

Of course, this is just their tuner kit, devoid of such things as tuning. Apparently, according to Jim III, the Roush kit will mirror the FRPP / Whipple in terms of pricing once Roush's complete kits are released.

 

The tuner kit is less, so should the warrantied kit.

Roush will probably do a Hammer style kit with a beefed up shortblock, big power numbers from it I'm sure.

And JDM is the king of making safe supercharged power on stock motors, they did better than anyone with the 2300 TVS Roushcharger on the 3 valve 4.6.

 

Yeah, $500 less. Is the testing and tuning that Ford engineers did for their kit worth the extra cash compared to the Roush kit? I guess time will tell. I guess only time will tell exactly what Roush will charge for their complete package, too.

I'd love to see a beefed-up "Hammer"-style kit for the 5.0's!

 

There's no way you could fit a STB over any of these superchargers is there?

 

$500 less than FRPP tuner kit, $1200 less than the FRPP tuned warrantied kit, Roush won't price itself out of the market so I would look for a base tuned Roush kit at $6999 or so.

 

Look at that pic I posted of the Roush kit, there is an indentation in the air tube for the brace.

 

You're probably right in assuming the complete, warrantied Roush kit will retail for around $7,000, just under FRPP / Whipple's complete, warrantied kit ($7,199). Again, is a couple of hundred dollars' difference worth paying for calibration written by Ford engineers, the very guys who designed, built and tuned the factory Coyote?

 

there is!

 

It appears as though the FRPP kit has an indentation, too. In fact, it appears both the FRPP and Roush kits utilize the exact same air box and intake tube.

 

The proof will be in the performance.

And Roush is also privvy to all that Ford factory knowledge too.

 

I would think the performance will be similar for both kits, assuming the boost levels are the same.

And, while Roush does a lot of engineering, data collection, validation, etc for Ford, they do their own, in-house tuning (at least, according to the Speed Channel special chronicling the 2010 Roush 427R's development). I'm sure there's quite a bit of data-transfer between the two companies, but I have to figure that no one knows this engine better than Ford. With 11:1 CR, and all of the other high-tech wizardry, I feel the key to engine longevity will depend primarily on how well the tune is written -- how well it utilizes the sophisticated knock sensor system, how well it can adapt to changing stress, etc.

 

Sweet, I'm glad they included that feature. Its cool that you can keep the STB when you have giant supercharger under the hood.

This. No one knows a system better than the engineers that designed it to begin with

 

And this. It is well documented that roush does extensive testing of their products, particularly with their power adders, which as mentioned are developed in conjunction with fords engineer team. This is why the previous edition of the supercharger was warranties for 36 months. I'm with you all that the ford engineers know the engine the best, but the roush folks are no slouch.

 

You're right, but a 3/36 warranty on an Eaton M90-boosted 3V 4.6L is a completely different animal when compared to an R2300 TVS-blown TiVCT 5.0L V8 (I have a feeling Roush's warranty on the full TVS kit will mimic Ford's 1 year / 12,000 mile warranty) . That said, I wonder what the supercharger of choice will be if/when Roush releases a supercharged 427R based on the new 5.0L? Will they continue to use the Eaton M90-based "Roushcharger" with a very conservative tune or will the TVS supplant its "Heaton" brother? I guess we'll find out in the coming months.
