Alright, so with TurboTrix coming here on the 11th, I was just curious what HP/Torque numbers people think I might put down on the Mustang Dyno at FIS. It's an '04 RS with the following mods...

Injen Intake with upper i/c piping
Hallman MBC set to 20 psi
Iridium spark plugs
Nology Hotwires
Megan Downpipe
Megan High-flow cat
Helix cat-back
Walbro Fues Pump
MR Diverter Valve
Getting TT to do a custom flash/tune at 93 octane

I'll post the numbers on the 11th, but I'd like some opinions...I know every EVO is different and they all put down different numbers. Let's just see who get's the closest!

 

298

 

between 275-290 whp... btw you need a fuel pump

 

ok, just ordered the Walbro 255 fuel pump...added to list

 

Maybe 284 if you are lucky. You need more parts!

 

stock cat high flow cat or test pipe?


blackevovii has same setup basicly - the upper ic and he has test pipe on TT's dyno put down i beleve 314 to the wheeles


so ya should be around that ball park

 

maybe a perrin cat delete pipe? this will complete the exhaust mods and you'll get a few more hp.... your biggest jump besides turbo will be cams + gears... so i wouldn't expect anything over 330 whp with every bolt on you can buy.... this is realistically...

 

stock cat for now. The reason i don't have THAT much done for performance is because I started out with the interior of the car. Added power windows/locks with door panels, center consol with armrest, visors with mirrors, gauge pod, dvd screen, JL speaks-amp-sub, and wing. now that i'm about done with the RS conversion...i'm ready to make it faster.

 

With the stock cat I think you'll be at 290 AWHP. Lose the cat and hit 310.

 

nice.. with stock cat probably puttn round 290 - 300 maby little less that should be at the wheeles i dont rember how the diff dynos run but that was on the dyno that TT has in their shop

 

Don't I HAVE to keep the cat or get a high-flow? If i get the test-pipe and get pulled over...i'm screwed!

 

TONS of people don't run the cat. However, it is very noble of you to take the high road and save the environment at the sacrifice of 20 HP.

Personally, I would rather remove my cat and then lobby Congress for sanctions on chemical plants, etc.

 

dont think so how tuff are emmissions around where you live? and just keep the stock cat for when / if you need to go thru a test.

 

If you get caught anywhere in the country its like 2500 bucks. Its a FEDERAL law.

 

Does not having a cat make your car stink when you floor it?
