Ok gang. I know that steeda, brenspeed, American Muscle and the like are reporting absolutely impressive results with their products. I'm sure they are all honest people, but they are selling a product. There have been some great reviews using the highly subjective butt dyno, but few posts with hard numbers.

So I thought I'd create a thread for those of you who have attained the substantial goal of 400 ponies (if you're over 390 chime in as well) at the rear tires. Give us your secrets, because many of us covet your achievements.

If you're running a manufacturers package, give us a sense of your results with it. Also if you're running one of these with less than spectacular results, you might want to chime in as well. Don't bash, but inform honestly.

SUGGESTED INPUT:

Baseline HP

Mods

Dyno results

Rate Drive-ability

Problems encountered (limp home, check engine light...)

 

^ I'm with him....let's see how you all got there...also, some idea of what you $pent to get to get to the 400hp Club...

 

well i plan on supercharging so.....lol once i get the car and the supercharger ill let you know

 

Ill start. I have no stock dyno numbers but I ran 13.0@110mph stock at the track. I have added,

Steeda CAI
Brenspeed 93 tune
Roush Mufflers

Dyno numbers 399HP and 380TQ SAE

Driveability and throttle response are AWESOME!!!
I have no track numbers yet. Coming soon.

I spent less than $1,000 so far on mods.

 

Is this a 4.6 thread or 5.0 thread?

 

showcar, very nice!!! That's valuable information.

JonW, I was thinking 5.0 as that is the new hot ticket.

 

That's VERY encouraging, since I was thinking along those very lines anyway. Thanks for sharing! Anyone else?

 

save your money. This guy's at 400 rwhp stock https://themustangsource.com/f726/factory-freak-488303/

 

Here are some HARD numbers for you...

Video of my current car's mods
http://www.youtube.com/watch?v=-FwYCngQwYM

Stock vs tune ONLY - ~400-450


Same Tune as before, added Stainless Works Full Exhaust - Not cheap, but she sounds evil. You could probably delete your cats for 10whp, but I cant stand the sound/smell of a catless car



JLT Intake - $350



Stock vs Current



Bear in mind, dynos are just a tool, not a trophy. Every dyno reads different. The trakc is where power is proven

 

Know a guy on the forum with an auto ( Jack's 07) who got 400rwhp. He has a Steeda intake, VMP dyno tune, or x pipe. Pretty impressive for an auto with those few mods.

 

 

This is great but you spent a whole lot more than $1,000.

 

I everytime I see that kenne bell

 

You just cant put a price on the kinda fun !! lol then there is that SOUND !!!
"I never could figure out if it was the whine of the SC or the whine of the loser behind you" !! LOL i love that line (or maybe i made that up either its all good)

 

Thanks! If you only knew how much I spent or didnt spend.... =)

 

I think its both!

 

i love the whine this video is like **** lol

Amen brotha!!!

 

Thanks my friend! Dude you ever go to Irwindale on Thursday nights?

 

I'm pretty impressed with the ease/lack of expense that is involved in getting 400 ponies to the rear.

Look at the new BOSS... 440 hp. 455 at the crank x .88 (representing 12% loss) equals right at 400. But on the boss they have worked the heads and created a new intake as well as tuning and other things for 440..... WTF???
