Latest Dyno results... 360/302 - ClubWRX Forum - Subaru Impreza WRX and STi Community and Forums

**MidKnight** · 12-07-2004, 12:50 AM

So I went to the Dyno on friday and here's what I got on my xs450/avo400... 360whp, 302 ft-lbs @ 23psi on 93 octane

I had a few problems holding me back from making more power.
1) I had a huge leak at the flange to my external wastegate from my uppipe (probably due to blowing out the gasket on my way to the dyno

) This is without a doubt why my turbo is spooling so slowly right now (~700 rpms later than what I was getting before) After doing some reading apparently the gaskets that are supplied with the Tial wastegate are garbage (so i noticed). Tial themselves says to use the gaskets from the turbonetics unit, so i ordered those already.

2) I need colder plugs. Junior was pretty adamant about the fact that with 1 step colder plugs I could run more timing and pick up some big power up top aside from the power I would get from fixing the leak I have. The ej207 loves a lot of timing and I can't run it with the plugs I have. I ordered a set of NGK Iridiums in the 8 heat range. Should have those in soon.

Over all, I'm pretty happy as far as how things have progressed thus far. Having over 300whp at 8k rpms is rediculously fun. I can't wait to get my issues worked out and my ra gearset in!!

WOW..congratulations!!! looks good.....you and 13secwrx keep going bigger and bigger...but it looks like he might sell his

so how big of a difference will the fixed leak make as far as hp goes??

Yea, it's sad to see Will selling his baby!!

As far as power form the leak, it's reall hard to tell. It's very audible. I had walked in there aiming for 375whp and afterwards Junior was more than confident that I would easily get that when all was fixed up. We will see...

AwdTurboWrx · 12-07-2004, 01:26 AM

wow 375whp ..nice!!! ..and better spool up once leak is fixed nice...are you planning on upgrading tranny?

nice #s are the RA's really going to hold that power though. esecpcially since youll be making even more then this soon.

Timdog1650 · 12-07-2004, 01:16 PM

Were you getting detonation or any kind of misfiring up top with this tune? Seems like you should have been running more boost than just 23lbs on that turbo. Bummer about the plugs though, it must drive you crazy to be ALMOST there when once again a few little things hold you back.
The 8k powerband is awesome though, isn't it?! I could spend all day and night above 6krpm and never feel a drop off....it's amazing!

PS your AFR's look super safe! How are your injectors doing, any idea what kind of duty cycle they're at?

I've gotten my stock gears to hold at 341whp for quite a while, so I'm pretty sure I can manage to get the ra's to hold. People usually say the ra's are good for about 350whp so I'm not too far past that.

I was getting some knock up high in the powerband, which is most likely a result of my plugs. That's on eof the reason I need colder plugs. I wanted to advance timing at least another degree before I started adding more boost. Once I get the issues sorted. I'll throw more at her.
It does suck being almost there, but even in this state the car absolutely rips! I get great pull from 5k to 8k (I need about 500 more rpms down low to really be happy), and the external wastegate holds boost very solid and boy does it sound mean!

Timdog1650 · 12-07-2004, 02:43 PM

You think this new gasket will give you 500rpm more to play with? I figure it should be good for a bit more boost down low....*ordered new plugs just now*

Fixing a leak like that can definitely give me back 500 rpms and some more torque down there. Like I said, we'll see!

Werd. Very nice, is the ej207 built or did those come with forged internals?
