I am sure this question has been asked many times but I haven't found a real definitive answer yet. I was wondering around a ballpark figure my car is pushing for hp and tq

2003 wrx jdm ej205
Vf39 turbo 18psi
Sti pink injectors
Perrin fmic
Walbro 255 fuel pump
Megan uel exhaust manifold
Tbe
Stage 2 clutch with short shifter
Cobb stage 2 ots map
Thanks for any input

 

300. Super guess

already told you, guess you doubt me. youll probably be in the 250-275 whp range.

 

^^^this

of course the cheapest way to find out is to borrow a tactrix cable and use Virtual Dyno and do a few pulls to average out a hp/tq benchmark. it won't be definitive but at least you will have an idea. i use it to track the difference in what my baseline was to what gains I made after adding parts/tune.

look up my thread on Open Source for all your questions in regards to logging and using Virtual Dyno

 

The OTS map is sufficient but will not pull peak performance, a protune is better. AMS is around the corner to visit, you may want to contact Shaggy.

 

Take a look at your question. Then think about it.

You want an approximately exact answer?
An absolutely accurate rough guess?
Or how about an almost dead-on suggestion?

You CAN NOT get a definitive answer. If you don't understand why, then you need to ask a different question.

 

do you have the AP? if so you have a map that works more efficently with your mods rather than the stg.2 tune. flash it....then you go online and look at cobbs website for an exact number you get from their OTS map. and there you go.
but as stated above, to reach the full potential of mods and car, a custom tune will definately be your friend, youd be amazed

 

what octane are you running? why do you have a fmic with a vf39?

 

^^^Cuz its mad-tyte bro!

But seriously...I expect about 270 whp with that setup...maybe more maybe less given the tune.

 

i like these numbers people are pulling out of their butts ... lets be honest numbers don't mean anything from a dyno as all dynos are different and altitude, temp etc will make all the difference. as long as the car runs well throughout the entire powerband you should be happy, but u need a protune if u want to see full potential... none of this OTS garbage. i'd be surprised if you could safely get 270 awhp out of that setup. best of luck

 

i like the garbage this guy is spewing out of his mouth because he thinks he knows something. considering we are on an island the altitude isn't going to change much and we only have one dyno here so basically the numbers will be pretty similar as someone who has similar mods. a lot of people have done similar setups so why would they be pulling numbers out of nowhere if the variables are similar? to the OP realistically you're gonna be somewhere between 230-250 with the mods and that OTS map. get it tuned and you might see 250-270 but it seems like you are just curious and don't wanna spend $ for dyno time. either way if you really wanna know put it on the dyno, otherwise it's just speculation

 

I'd say 250whp tops with a slow spool since fmic and especially on a higher end mileage motor ej205(guessing since it is an 03)

 

Why don't you just go to Cobbs website. They have the dyno graph for that map posted there.

.... And then shift it right a few hundred RPM for the FMIC.

 

thanks for all the input guys, i have a fmic cause i came across a deal on the perrin for more than half the price of a brand new one so i jumped on it. As far as not wanting to spend the money on a tune i plan on getting a pro tune soon. It is a ej205 the jam motor with only 58000 miles. any other "positive" input would be helpful.

oh and btw i really don't see much turbo lag i still hit 18 psi in 3rd gear around 4 grand maybe less, i haven't paid that close attention to that number
