Thank you for this. So my numbers are definitely low for my mods. Considering it was 5 years ago, the 8 was very near to being new. So that right there probably nets me minus 10-15 at the wheels wouldn't you say?

Thank you for your input.

this...

coming from an R1,you need a bigger turbo if you are looking for a fast car.the EVO is not really what i would call a fast car in stock or even close to stock form.

you were hoping for 295 and you got 267.that isn't much of a difference.25whp in a 3500lb car is not much.i'm betting that if you get the 295whp you won't feel a difference anyway.get a 9 turbo or even something bigger and you will be happy.

It could be a weak wastegate actuator.

You are missing the biggest variable in this whole analysis. What were the baseline numbers on your Evo? If you don't have baseline for you car then what does a stock Evo 8 typically put out on this particular dyno? Forget the low numbers....what is the difference of before and after. Once this is done then you can look back and see what step to take next as far as mods or maintenance.

I have seen a Evo 9 with an intake, mini battery 3-port and fuel pump (everything else stock) make 265 whp. Sounds low right? Well I found out that a stock Evo 9 puts our between 205-215 whp. Thats a minimum of 50whp difference.

On another note, I haven't seen too many stellar results with S1 cams or the Threadstone IC.

Your advice is a bit contradictory.. Here's how: the claim that the difference between 267 & 295 WHP will not be really felt - the cure to the OP's low numbers is a 9 turbo. In the massive amount of dyno runs covered in multiple threads on various setups it has been shown that simply swapping out an 8 turbo for a 9 turbo only nets a gain of 20-25 WHP at the same boost level. Is it felt? Yes. Is it worth it? For the money, yes, but ultimate goals need to be considered if the 9 turbo would be the proper turbo for the desired power level.

OP. Stock Evo 8's dyno'd in the neighborhood of about 18-19% power loss from BHP to WHP. So that would put your current power level to 320+ BHP. I wouldn't be too disappointed given your basic bolt-on mods.. that's a 50+ HP bump from stock.

i made 356 389 tq on a mustang dyno at like 27 psi i had all boltons no cams stock block and head

i have a 9 though

no my advice is not contradictory and no it will probably not be felt.

i told him to "get a 9 or BIGGER turbo" and i never said to run the 9 turbo at the same boost.that would be ignorant if you were trying to make more power.obviously if you want more power run more boost.and yes the 9 turbo is capable of more boost and more power than the 8 turbo.it's a bigger,better turbo and everyone here knows it will make more power than the 8 turbo,except maybe you.come on man.

go nit-pick somewhere else.i'm trying to help the guy out.

25whp is not much and i know i couldn't feel it,maybe you could.

I'm digging the optimism, I plan to swap turbo's and keep you posted.

Though I don't mind paying for a quality tune, just curious how much in total a tune is from there?

That's really what I'm hoping. Only time will tell, after I swap turbo's I will obviously swap WGA too. I'm really hoping my numbers sky rocket due to it being a WGA malfunction

Unfortunately I bought it used and didn't run a baseline before cam install. Hindsight being 20/20 I should have gotten a base. Rule of thumb is stock evo's run like 235 whp I believe on this mustang dyno.

Also, the tune was BEFORE the fmic so that couldn't be the issue.. Everyone who I talked to about the S1's loves the power right out of the box while leaving the stock valve-train.



This put a smile on my face.


Yeah I went to my tuner because I read he was good on this forum. I'm not sure it was his fault, someone PM'd me and said they got 295 at the wheels from similar mods from the same tuner/same dyno.

I really appreciate all of the responses guys.

After considering everything, my plan is to do a compression check followed by a meticulous boost leak test, injectors/turbo swap/e 85 tune.

My fear is that I am throwing a band-aid on a larger problem and that no matter what I do, I will always be 10 % under-powered.

Only time will tell. Always open to more opinions.

hey man, just in case that is in reference to me. Just wanted to make sure it was out there, my tuner at the time was Bryan, who no longer tunes the masses.

ahh ok thank you for the clarification

UPDATE FOR THOSE WHO CARE

Ok so here's what I did since my OP.

- Compression Test 125/125/130/140 (near %10 difference but nothing to be worried about I think)
- ABSOLUTELY NO BOOST LEAKS

- Swapped out stock turbo for a fp hta 71(white)
- Megan 02 housing
- Turbosmart 22 psi WGA
- Treadstone 3.5" Intercooler
- fftec EBCS
- Switched Tuner (sean @ fftec)

I saw a 50 whp gain (mustang dyno) from the above (still on CA pump 91).

So now I sit at 315/305 on a mustang dyno. Still (I feel) about 30-40 whp under where I should be at.



HERE'S WHAT I THINK MY PROBLEM IS, TELL ME IF I'M FAR OFF:

Problem For The First Time Around (OP):
- I believe what was wrong the first time around was a S&*TTY TUNER. He had absolutely no idea what he was talking about and his tuned sucked *****.



Current Problems:

- Injen LICP connects like crap to my intercooler. Almost impossible to explain, but basically the elbow coupler reducer and LICP bends to create a small scoop internally. The Injen LICP sucks to begin with I am figuring out, and this internal scoop that is restricting flow isn't helping any.
(8-10whp loss)

- ****ty California 91 gas? I am going in to get tuned for E85 on Friday, I will post results when I have them.

- Possibly losing power due to semi low compression in cylinders 1 and 2? (125/125/130/140)
(10-20 whp loss)

- Still on stock exhaust manifold.
(10 whp loss)


So all said, if I switch these parts I think I will be right around where I should be.


Please let me know if you agree or disagree with my diagnosis and more importantly WHY. Thanks.

you took your Evo to a Subaru shop, that's your problem... head over to FFTEC
