Stock Dyno Run by RRE

[Ladogaboy]

First, I'd like to thank Mike for giving me a run on his Dynopack. He even let me get my hands a little dirty.

Stock, I ran 223 hp and 250 tq. Mike mentioned that my car is running a little lean for stock, and he noticed a bit of knock. I'm hoping it's not too big of a deal, but I might want to reflash sooner rather than later.

And if you wondering how much HP the A/C uses... the first two runs (red and green lines) were with the A/C on :-P

The run file says Subaru because we were comparing his pulls to a WRX and that was the last file opened as comparison.

I think the runs with the A/C on were a better estimate of the actual power I am seeing. Living in SoCal, I'm probably not going to be turning it off very often. ;)

I'll have to send you the video of the dyno pull.

...or I can upload to youtube - your choice just let me know.

You could probably just upload it. Candid camera! :p

My Dyno run was done on a Mustang Dyno and my numbers were 191HP 217Trq
on the second pull. My Average was 141HP 174Trq and this was with a magnaflow axelback with resonator delete, Hks ssqvIII blow off valve and 91octane... maybe the 3rd pull would of set the numbers straight since the 1st pull was 43Hp 110Trq and the second was 191HP 217Trq

Could the presence of the VTA BOV be the cause of you less HP and Tq numbers? The RA is a recirculating system stock right?

I ordered a dual port BOV for my 2010 rallyart sportback and it was full metal came with adjustment springs.
I tried both pair of springs but I started to feel that the boost was not picking up as quick as before.
The problem is boost leak from the BOV put the stock back on and the boost was back 0-60 times picked back up perfect.
So what I would say is upgrade to the EVO X stock BOV and you will be good.
This will be the best course to keep your power and you worry free.

With that kind of disparity, I would have liked to see a third pull as well. Each dyno seems to read differently (unless they are from the same manufacturer with the same settings). The main thing to use these readings for is to create a base map, and compare gains once you have made your modifications.

I think it might be because im running none recirculating on the bov, i've heard the recirculating STATUS IS BETTER FOR MITSUBISHIs. So if i went from atmospheric to recirculating it might help... But i love the sound of the bov.. And if i circulate it removes the sound completely :( so sad!

[Jdmboi]

thats cool good numbers.......did he give you free dyno runs I want one lol.....jk.....

[2010 Rallihead Sportback]

should i set the BOV back recirculating? does this cause any boost or performance problems

[hackerrei]

I would say set it back because i was reading some thing about how RA and EVO ECU is setup to re use the boost that is left in the tube after the bypass re directs the air back and it is setup to use that presher agen when boost is used so there is always boost there if you let it out the ECU still thinks it's there and try's to use it to keep the boost up through the shift range.
You let the air out it
