Newbie here so I apologize in advance...

Evo IX SE with:

-Custom tune on dyno
-3in exhaust (not sure if going w/ cat or not)
-air filter kit (cone)
-Manual boost controller

Also, should I have a certain # of miles on the car for break in b4 performing these mods? I have 300miles currently.

It's my new daily driver, so starting off small and trying to keep the car relatively quiet (cat really quiet things down or not so much?) . Just wondering if this is enough to make the old men in Porsche's spill their Starbucks all over them or not?

thx.

 

really depends on what you use.
what PSI you plan on with what Octane gas?


probably around 310-330 i would geuss i dunno maybe more with that tune being good. Rough geuss

 

thx for the feedback Kaonashi....that enough to take on the locals?

 

lol if the locals are ricers, and the domestic guys who have corn cobs in their .... well yeah

Stay away from the big guns lol

Please do not launch your car without reading about the proper way to

 

around 300 ponies

 

around 300 whp on butt dyno.......

 

Ideally drive 1000 miles before modding.
Go for a catless exhaust, it'll get you a touch more hp, and same price. plus, it sounds a lot better.
power? 330-350 with a good tune

try doing what i did - I have effectively those same mods (plus some little stuff that doesn't add much power) and tune for race gas. it works out good for me, cause its not a dd and i have a race gas pump by my house. you gain a TON of power by doing that, it's a blast.

*and by good tune i mean pretty aggressive, haha

 

93 octane. I realize one of the EVO's advantage is abilty to launch, butt I like my clutch, we'll see how many 5k RPM launches I'll do haha.

Catless exhaust may sound better when u want to hear it but on a 4 hr. highway trip with the GF I want it to be as quiet as possible. I heard the cat restricts power (obviously) but doesn't really quiet things down much on a full 3in exhaust...true or not?

 

Aftermarket high flow cat will quiet things down somewhat. The stock cat is like a brick wall, get rid of it immediately. Try to purchase a quiet exhaust as well, if that's what you need. Search the word "quiet" and you'll find endless info on your choices..

Buy (or put together) a turbo-back setup before you go get tuned, most 2.75 or 3" downpipes out there are pretty cheap and nearly identical. Go with a test pipe or HFC, through to your catback exhaust, and you'll get the most out of your tune.

Edit: but break it in first!

 

Screw the clutch worry about your TC alot more expensive than a new clutch

 

Thats exactly what I've done to my IX, and I made 336whp/337wtq on a dynojet at 24psi.

Here's the link: https://www.evolutionm.net/forums/sh...d.php?t=280547

BTW, if you can deal with the noise/odor, get the test pipe. You'll probably get around 10hp from it, but more importantly the Turbo spools much quicker.

 

awesome 06rs, thx for the link. U went with test pipe...hypothetically, would u be comfy driving into a quant, quiet neighborhood at 6am to drop your kid off at day care or do u think u'd wake the entire street with the noise from your exhaust? Also, would u be comfy with a new GF in the passenger seat (who isn't so into performance cars) driving from philly to NYC or would she stab need earplugs?
(trying to get a feel for how loud a cat-less exhaust is. thx.)

Also, do you find yourself being able to smoke the average M3/S4/lower level Porsche during your daily commute?

 

The noise a test pipe will produce really depends on the exhaust system. I have a Buschur TBE with a Magnaflow muffler. My exhaust isn't too loud. It gets loud when you get on it, but just cruising around at low RPM's isn't obnoxiously loud. I f I had the Buschur Bullett muffler, that would be a different story. Use the search function on this site, and you'll find a number a threads dealing with loud/quiet exhausts. Some people use resonators, and resonated test-pipes to lessen the noise.

You'll be fine

I don't street race, but I don't think any of the cars above would stand a chance. (at least until 100mph)

 

with just a TBE(w/test pipe),MBC@22-23psi, and custom tune I made 342whp and 328wtq on a dynojet....I've since then added acouple things and maybe have around 350whp now havent dynoed since the tune.
