I had the Roush 625 hp upgrade installed on my 2011 automatic. Dyno'd on a Mustang dyno in 3rd gear , on a day with a heat index of 104 and dyno'd 439 at 5000 rpms. I wanted the Roush tune cleaned up; better throttle response, no more discolored tail pipes and more safe power.
I spoke with...
#1 Using an example of 625 crank hp on an automatic. I know there is a 20% reduction ; so 625 crank theoretically becomes 500 rwhp. Does a 3:31 gear ratio reduce that rwhp or does it have any affect at all ?
#2 I've been told a Mustang dynojet reads lower than a dynojet; if so how much lower...
Corsa xtreme ABs- $500.00 ($825.00 new)
Corsa X pipe - $150.00 ( $275.00 new)

I bought my 2011 GT automatic with the plan being to eventually adding the Roush TVS, rims /tires and suspension set up giving me the mechanicalls of a Roush stage 3. I have the Premium GT pkg with *accessory 5 pkg. I added 3:73 gears courtesy of TERREBONNE Ford. I spoke with Joe Mitts at Roush...
5.0 auto with Procal tune , drop in K&N, 3:73s, Corsa xtreme AB and X pipe.... would Cobra rear lower control arms be a good mod? Planning to add a Roush TVS this spring.
Just for the hell of it I called FRP and inquired about the Ford SC on an auto.The reply was " they offered it up to 2010 and there was not enough demand to warrent the programing". I guess they don't read these forums or they are not listening to us the customers or do not realize how many...
I have 3:73 gears( auto) with 245 P zeros on 19.5" rims. Does the height of my tire increase or reduce the 3:73 ratio effectiveness; IE: with the height do I have more or less than 3:73 final ratio?will I get more from 18"s or 20"s or does it really make a difference?
Thanks

I'm running stock 19"s with P-zero 245 /45/19. What are my options for a wider rear tire - retaining the stock rims and not bulging out the fendor well ?
My 3:73s are installed and I have a big silly grin on my face. Thanks to Terrebonne Ford - John Jacousso / Lance and Russell. I kept it simple.... Corsa x-treme axleback & x pipe ( Fast Eddie @ Southern Hotrod) - Ford procal tuner & drop in KN and Ford 3:73s . The Ford parts were dealer...

Thanks to Terrebonne Ford -Houma , LA.- John Jaccouso and Russsel L installed the K&N filter and tuner.
The K&N was a simple drop in and we capped off the sound tube with a cap from JTL intake. It was nice to hear the true sound of the Corsa xtreme and X pipe.
The tune process took about...
