Whats the HP ??

[Mike Papas]

Has any of you dyno your 05 or 06 Roush mustang to see whats the rwhp with out and with S/C ???? and after you install S/C what else can you do to add more H/P ?

On a Mustang Dyno - 252 rwhp, 265 rwtq before. Currently with Vortech SC 378 rwhp and 389 rwtq with a safe tune, doing final tune later this week. Mine is an Auto trans, so if you have a stick you'll probably do a little better.

You can change pullies, port heads, change cams add long tube headers etc. But you really can't push the engine much beyond 450 bhp or she won't last. Unless of course you change the lower internals to handle it.

I'm running 3.73 gears and JBA shorty headers in mine as well and it is a blast to drive and get on it. Decent gas mileage, 22 highway and 12 - 14 around town, but worse if I drive it hard around town.

With bolt ons and no S/C, 294/310 RWHP/FT. That's running 20's and 4.10 gears, so if you got stock 18's and gears, probably a little better.. That's a C&L intake, JBA LT's w/catless H pipe, off road roush exhaust and underdrive pullies.

I ran mine on the dyno 2 weeks ago and mine ran 271RWHP and 297RWTQ. I have a stage 1 and this is completely stock. I have not done anything to it yet. I am waiting to get the supercharger put on. The guy that does my dyno said that he has seen 440-450 RWHP after the supercharger with tune. Wooo Hooo!!!!

how was the change from 3:55 gears to 3:73 gears? I've been reading some about gears. What's the tach read at 80 mph? more torque? what are your comments?

290/311 with intake/tune/hpipe. $800 in mods and worth every penny.

[LVROUSH]

356 RWHP and 334RWTQ with Roushcharger, conservative ROUSH tune and boost. No other mods.

Witht he roush they specifically say that headers , cai etc actually hindered performance. I think any would that would help performance roush would have had in the kit. When you see the minor changes to the standard air box they do it make you realize the reserch that went into it.

Besides with hp with the s/c the cars ahead, you catch up to real quick

Saw this guy run on the Roush mobile dyno with an '06 with Roush charger and he put down 369 rwhp.

Makes me feel even better about my numbers- I have a roushcharger and a basically offorad exhaust. Just dynoed 378rwhp on a brand new dynojet. Im pulleying down as soon as it is available, and after changing internals, going with larger fuel rails, injectors, methanol injection, and a custom tune. Wish Roush offered a tuner!

I am putting 452 RWHP (aprox 520-530 flywheel) with my procharger. I am at the edge of what the stock motor can handle. New motor on the way, stroking her to 302.
