What does it take to really get your 305HP

Alright guys, lets stur the pot a little..... Anyone who will be honest with themselves will admit that out 305HP is really more like 270 (on a good day) at the wheels. So, the question here is simple, what needs to be done to get all that 305 at the rear wheels?

The 305hp that Ford rates it at is at the crank, not the wheels. Factor in drivetrain loss and 270hp at the wheels is right on the money for what Ford rates it at. Now if you're looking to break into the 300s at the wheels, a CAI, a full exhaust swap, a good tune, and maybe a throttle body may get you there. But what's HP without a bit more torque to go with it haha. Throw in some 3.73 or 4.10 gears too and you'll be grinning from ear to ear.

My car was 268 stock, after installing BBK long tube headers, xpipe, Roush cat back exhaust, Airaid CAI, Throttle body spacer, 3.73 gears, and a hybrid tune from Bamma. My car is sitting at 308-312 my best dyno run was 316 and that's with my engine being nice and cold!

Nice that's over 40hp In increase. How much did everything run you? I'm guessing around 2k...

headers+xpipe= $400 retail is 996
Roush catback exhaust= $600
3.73 gears kit with tuner= $500 retail is 599
Airaid CAI=$256
Throttle body spacer=$65 retail is 99

So around 2000 with gears install give or take 50 bucks

Saw a 2011 on youtube with a CAI, tune, long tube headers, X pipe and axleback and his rear wheel was 315hp.

There is alot you can do to get up there to the hp and tq numbers that is at the crank. The first way and easiest way is to install a cold air intake Exhaust and a tune that will get u pretty close to those numbers. Also a buddy of mine changed out his stock drive shaft with a lighter carbon fiber drive shaft and claims that he got more hp on a dyno. Then there are superchargers, turbos ad manifolds you can install to gain more hp.

Yea the aluminum DS will increase rwhp because of less rotational mass and wi free up more power

And the gear you chose take away HP (but add torque as it takes HP to spin the steeper gear) so that number would even be higher if you had the stock 2.73 rear in there.

Nice gains.

I would say that your gain there was the tune. You have to remember that the tune will allow you to maximize engine efficiency with your aftermarket parts like a CAI. So a bolt on CAI may give you 12hp off the bat but program your computer to use the most of that increased airflow and your 12hp gain is now 15hp. This works the same with forced induction as a small change will give you a larger gain.

+1.. I agree. Bolts on plus tune equals quick gains. And in our new engines is easier to squeeze more out. But simply changing your gears will give you that boost w/o actually having 305 to the wheels

A steeper gear will always use more HP to turn it. It will however increase the torque. Just the opposite with a taller gear as it will gain HP but lose torque. (If you were looking for more top end speed) So in your case torque will go up a bit but HP goes down. My guess is that it had to do with the atmospheric conditions like heat, air density etc. on the 2nd dyno run... might have been cooler out or better airflow when you did the second dyno run. Or perhaps you had it run on a different dyno? Every machine is different because of calibration. Also, Different days give different results on the same machine, same car etc.

I would always choose a little more gear than HP for a street car anyway. Much more fun and you can feel the gear down low which outweighs the comprimise of a few HP loss IMO.

comparing how my 3.7 feels to a stock 4.5 3v the 3.7 feels like its about 30hp under the 4.6 until it hits about 4k or so~ then it feels about the same.

Well I had a tune before the gears also, so instead of a loss of HP with the gears like they stated I gained a bit but idk it could be that days weather conditions or something cuz u never get the same HP twice on Dynos

Yes I do! Stock I was doing 16flat! Now with all my mods and on race days I install my 93race tune and I'm doing 14.1 I'm sure if I get my slicks I can do 13.7 and I'm also getting a torque converter soon so that should help!
