^^^the newer cars will make 250 whp with just an intake, he'll be near 300 on a dynojet, so a little less than that on a mustang

May I just please have a quick explanation why? Last meet I saw plastic bpv's and intake manifolds with tiny intercoolers under their hoods. I mean, I'm just a hater in a hawkeye, but c'mon. With all the work it took me to achieve my numbers, it just doesn't seem to make sense

Intake, turbo back exhaust and tune will probably be around 270-280WHP on a Mustang.

It is because the 09+ WRX's have the VF52, which is an STI-size turbo.

Aaaaaaah, no more td04's. Makes sense. So they run the same VF the STI's do now. Interesting.

VF52 has a different flange on the compressor housing, but it is essentially the same size as the VF48 that the STI uses.

A mustang dyno reads lower than a dynojet, correct?

So couldn't dynojet hp just be translated to crank hp?

For example... if you're making 340 whp on a mustang, that would be translated to around 400 crank hp, and I'm sure if you took it on a dynojet it would read around the same.

Any input?

340 whp is more than 400 chp.

Though, I have no idea why you'd want to convert any number to chp because it's just a marketing gimmick.

A Dynojet is measuring power via the wheels, so it is wheel horsepower. It is not directly connected to the crank, so it is not crank horsepower. You can call numbers whatever you want, but the way in which they are measured is what really matters.

FYI, a stock STI will usually do about 240WHP on a Dynojet (not the rated 300 crank HP).

I agree with this too. Who cares about crank HP? It is all marketing.

FYI, assuming 20% drivetrain loss:

340WHP / 0.8 = 425CHP

2005 4eat (I know, I know..) WRX with 84,xxx miles on it. Stock with the only exception being a SPT CBE.

Planned mods are the stage 2 necessities: Invidia DP (most likely catted), Cobb AP, and Cobb SRI.

My goal would be a reliable 300-350 whp as this is my DD. If those goals are too high, tone them down a bit for reliability. Can`t afford to sacrifice reliability for HP at the moment, and I`m not into financing a motor build atm either. Thats future plans all their own

Not sure where exactly this would be dyno`d, but most likely somewhere in NEPA/NJ. Not too familiar with dyno`s in the area so maybe someone with more knowledge could help me out there.

Not against a FMIC in the least, but if I could get by without needing to do it I`d rather stay TM for the time being.

I`ll be running 91 octane from Shell.

Thanks for the input in advance

You will not see anywhere near 350 on a stock motor. On 91 octane you need to be aiming ~270 whp peak. If reliability is an issue, don't surpass stage 2 (~210-220 whp).

Without doing a complete build, is there anything I could do internally to help make ~270 whp more reliable?

Do yourself a favor and put your next $1000 - $1,500 dollars and get some valving and a higher stall TC in that 4EAT. It will waken that car right up. Done right I think a 4EAT could be a fun ride for those who don't like to shift in traffic. 4EATs are quite torquey.

This video has been here before, but I always like to see it again

The downside is that it does affect the streetability of the car.

As for the valving, he's talking about manual valve bodies.

TC is a torque converter that will stall at a higher rpm. Meaning if you put your gas to the floor right now, it will stall around 2400rpms. When you let up on your brake it kinda just goes... plaugh... and falls on its face.

A new TC will stall higher, ( I think common ones for the 4EAT are 3500rpms but dont quote me). This will get your Rs up and you will begin building boost before you are even in motion.

The valving is a little harder for me to explain simply. . . bottom line is your trans will shift quicker, resulting in a jolt in the car between gears, rather than just popping into the next gear like it does now.

You do that and 1st and 2nd just became a lot more fun. Shoot - you can run a 1/4 without even going into 4th in that car untill you are trapping higher than 118 or so mph.

Having said all that, I don't miss my 4EAT at all, and I love my 6 speed

Gotcha. That was a pretty easy article to read, even for a newbie like myself. Thanks.

So basically to sum it all up..Max out at stage 2 with corresponding mods, plus a higher stall TC and possibly a trans cooler. Anything beyond that would necessitate a complete motor build?

Not necessitate, just increase the chance that something bad will happen and increase wear. If you're not in a position to fix it, don't go that far.

Fair enough. Thanks for all the input, it`s much appreciated!

As for the Valving and higher stall TC, what brands should I look into when purchasing?

well, the 80,000 miles is what could throw me off, but the glass ceiling I have set for the 2002-2007 wrx's is roughly 325-350 whp - more than that means the trans is susceptible to destruction from simply brute power. Stock internals are also peaked, because, as noted, that's over 400 hp the motor's churning out

1. HP at the WHEELS (whp)/ Achieve 350-400 whp.

2. What type of dyno are you going to be shooting for this number on? Mustang Dyno

3. If possible, tell us what shop it is. Someone may know how high or low that particular dyno reads. Andrewtech/TurboXS

4. Where do you live? If not a well known city, what is the elevation? Baltimore, MD area

5. What kind of gas will you be using? (octane level) 93 octane

6. Are you opposed to a FMIC? not really

My Suspension is:
sti sway bars and aluminum front a-arms
STI rear trailing links and lateral links
STI Brembo big brake kit
Tein flex coilovers with EDFC
whiteline steering bushings
white line anti-lift kit
carbing front strut bar
andd kartboy end links front and rear

Currently running all supporting mods for Cobb Stage 2,

Stock Motor, Trans, and Turbo
Planning to get a PPG (1/2 straight 3/4 helical) transmission in a year or so.
Turbo I was thinking an 18G or a Garrett?
For Motor I have no clue.

Car is a DD, let me know if I should lower my goals or adjust what I planning for turbo/transmission. As for engine, I sort of want to keep my EJ205, but a complete noob on what internals to get to reliably/safely support 350-400

Thanks in advance for any help

^Pistons, rods, TD05H-20G, and supporting mods will gt you there. TurboXS does not use a Mustang though.

Any suggestion for pistons and rods?
and benefit/differences beteen the TD05-20G and the TD06-18G?
what kind of dyno does TurboXS have? I haven't actually been there yet. Who has a Mustang Dyno?

What other supporting mods? fuel injectors, fuel pump, and what else? can i stick with a TMIC or be better to switch to a FMIC at that point. I dont plan on going any higher than 400.
