best way to get 400whp??

[wrxtuner82]

Is there any way to get to 400whp with just bolt ons? Not changing the trans, engine, internals. I'm just curious. Anyone know what you could really max out on with bolt ons? 2008+ wrx's.

[wrxtuner82]

I know someone is going to jump all over me screaming about this question because they had too much caffeine this morning. Relax, it's just a question.

[DHGurs]

Not really. Of course it depends on Dyno, CF, etc. Have a look at this (http://www.3gwrx.com/forum/index.php/topic,15232.0.html)guy, making 401hp with a built short block. He even races it and it's a very well balanced car. It's by far my favorite 3g WRX.

[yaya]

I would say it's relatively easy to do with meth or E85.

[AExiOn]

I would say running meth would boost your numbers, along with a very expensive huge turbo

Will your wrx trans like it.. probably not :p

I don't really wanna race my car though, I like the sound of it and knowing how much power is there, but I really lost interest in racing it around when I realized the price of tires, brakes, clutches and transmission parts

Sell WRX

Buy Viper

Profit.

I said the same thing about rally :lol:

I dont know how stronger the 08+ wrx trannys are. But I would say 400 would be pushing it on lets say on a 02wrx. But that is one thing you should keep in mind if your looking for that much hp

[wrxtuner82]

I'm lost on where the profit is???

[AExiOn]

you would have a viper??? :rofl:

And all the time saved from fixing everything that grenaded whenever he decides to tap into the 400hp in reserve.

[jwebsta32]

Why do you want power your not gonna use.400 whp DD SUBARU would be annoying to drive on street all the time. Not worth it imo, but give me 10 grand and I will give you a 400 whp SUBARU

[Joe]

This! plus they are 500 hp, so you get 100 extra.

Truth!

Why do you want power your not gonna use.400 whp DD SUBARU would be annoying to drive on street all the time. Not worth it imo, but give me 10 grand and I will give you a 400 whp SUBARU

Double truth!

In all honesty, if you just want a nice daily with some sack, go stg 2. then the car will be quick, driveable, and less prone to break. and the extra money can be put into your suspension, handling, interior, exterior, etc. thats just my 2 cents though.

[Berge56]

give me 10 grand and I will give you a 400 whp SUBARU

I'll do it for $9050 out the door. :)

You can't! Your transmission wouldn't hold it. Plus have you ever driven a car with that much power? It is not needed unless you plan on racing. It is your money(or credit cards).

[hiprsha666]

I wouldn't risk it on that tranny unless you plan a 6speed down the line. You might be able to get away with the tranny if you never launch or anything. But the internals are no good for that much power from what I understand.

[wrxtuner82]

I don't know why I want that much power on a daily driver.....I guess just to know I have it

How about this:

You go stg 2

You pay the 3500 i need to get my car to where it should be motor and suspension-wise.

whenever you feel the need for big numbers, we can ductape my car to yours, and BAM!! 500 WHP.


I think this is the best decision.

Sounds like you need to think about this a little more... Or, buy a car that already has 400hp.

[98Wagoon]

There's not much left of your transmission as it is... But.. Giant turbine, injectors, e85/naws, interfooler, tune. Make one or two passes at 400awhp, then buy a new car because the internals and transmission are behind you somewhere :shrug:



Ask gaddis the right way to build it, he knows..

[Joe]

Or try to not focus on the number you want, but more the results you want. handling, when power comes in, how far it carries. Then aim for those goals and be fine with the results. Shooting for numbers is a silly way to mod. they are just figures, doesn't mean your car is better or faster, just that is can spin a dyno with a certain force.

I think you should start with 300whp and see how that feels.

What's the fastest car you've ever driven?

Keep in mind:

-You will still be breaking stuff non-stop (spun bearings, piston ringlands, axles, tranny (you already know how delicate those are :D))
-You will get 8-14 mpg
-It will end up parked in the garage for long stints of time while you get other things fixed
-Just tell people your crank HP number if you want to impress people with #s, aka I have 450 BHPs
-What if an airboy/dynojet reads at 400 then a Mustang reads it at 360?
-DDing my car I've NEVER wished I had any more power than I have, it's hard enough to restrain my self with just 300ish whp.

[Subyspeed]

Honestly I say do whatever the hell you want but I would suggest thinking about all the speeding tickets you will get with 400whp. Once you have it you will obviously use it and since you don't want to race your car than that means speeding around town and that will eventually lead to speeding tickets. Just my :2cents:

kburnell can tell you how true that is. :lol:

I only have a little over 300 whp and it has gotten me into enough trouble as it is. It only takes a few seconds with that much hp to get 20 + above the speed limit so why go for 400

290-300WHP/330-350TQ on a Mustang with 2800-3000 spool for the street is a BEAUTIFUL THING :)

330-350WHP/350-370TQ on a Mustang with 2800-3000 spool for the street is WORK OF ART :D

400WHP/400TQ on a Mustang (no choice on higher spool) for the street is a CAGED LION ready to attack it's owner at any given moment if not careful :spin:

would be helpful... however Brian is running an sti. So his engine, trans, brakes, and internals are all in waay better shape to begin with. plus im pretty sure ive never seen him get above 2500 rpm. :lol:


wrxtuner is starting with a 2008 WRX. so a big turbo and injectors is great, but he will pop his motor and trans a whole lot easier.

Trans is missing 1st gear already..

[BG @ BrenTuning]

You will be on the verge of the:

Stock motor
Stock Transmission
Stock cooling system
Stock drivetrain in general

If you have deep pockets and love your WRX, by all means.

For cheap/fast/reliable as all 3 - start with a different platform :)

He didnt the past weekend because of the new fuel pump...but trust me when he does get on it haha boy is it a sight to see!!

But for a reliable 400whp in my view is not possible on a Subaru. It may last some people 10-30k but the overall group of people that use the power it doesnt last on the OEM engine. It's not the bearings but the pistons as everyone knows.

I would just buy a forged shortblock(run stock heads w/ cams

Run an ATP 30r

Supporting mods

this would be the closest cheapest reliable true 400whp subaru I can think of. As for the transmission that all the way it is treated but will most likly fail at some point during a pull.

We have an ATP30R car 2004 STi on OEM SB over 120k now....Making 395-415whp depending on dyno. It was tuned conservatively but it's his daily driver (100 mile round trip) I will be curious to see how long it lasts.

For a good daily driver I would say less then 400whp, more like 350whp is a good "forever" power level on mostly factory equipment.

will he? where will whats left of his trans go? and he cant stay out of boost, even sitting at a light.. so when he's driving around and not paying attention and runs out of meth on a back road and his sooopar advanced timing lunches his engine, then what?


fix the tranny. go stage 2. then decide.

[Seraphinwolf]

Now we all truly know the real answer is H6+6mt+boost but that's just retarded right? Right!

Anywho on the whole options thing he can just do stage 2 and then maybe add Meth and if he gets an Accessport or anoter way to jump between maps he can have his safe easy maps and then one that IS 400whp if he really wants but the list is still pretty much the list of what he'll need.

go for a torque line.. hp is screaming air and light fuel, and it is annoying.. but that is racing of course.

a much older mentality to look at is early trans am v8 cars (they square the power and torque), and a famous comparison is the gt2 and gt3. they reverse each other on the same engine..
one has giant torque, and drivability, the other has dropped torque and big air/rpms. (top end rider).

I by my own nature want the torque monster as a racer (not often, except maybe nascar), and subaru has gearing to go either direction you want.

4.44= racing
3.9 has a chance for the mature torque curve.


boxers vary huge in either realm, even more than v8s.

this is a good pursuit.

I joke of my own humbly... I am working for 90hp, and 150 foot pounds, while hypermiling....very truckish being that small. It is the type of car that does not change a gear on a hill...just when racing minds think it might. It is funny.
two worlds same machinery.

For a stock motor/tranny I'd say 300whp would be the max for long term.

These motors/trannys weren't built to handle that much power, we're talking about a wrx here and not a sti. And since you've got the 2.5, the hp won't kill your tranny... The tq will :lol:

just get it to a happy medium and enjoy it :)

Remember Justin his is 08' so it's like the 05-09' Legacy's and MUCH stronger than the older one's.

Yeah but they can break even under stock power...

Fixed. :unamused: Pretty sure I told everyone not to call me that.

I'm doing things in steps because it's something Randy told me to do. Make it stop, make it turn, make it go. So I'm doing it in that order. I finished the brakes. Now I'm on to buying suspension parts almost done with that and then before leave I'll be able to buy a couple performance parts.

Sorry. :hide: remember we were both used to that for so long...
