Man now I REALLY need my BCS & Fuel Pump. Need 3 more ft-lbs on my car to get ahead of Eric! :lol:

Awesome curve, can't wait to see how it does when he gets a new bpv :up:
Just curious, why the low redline on his?

It's really hard to road dyno the spec b, the log likes to break up in the high rpms and actually start to go backwards in the log :lol:. So we cut the log off there. Car goes to 7000 rpms.

The best part of eric's car is the torque in the midrange. We were able to hold it super flat due to fmic/bcs.

Ah yes, nothing like the rpm's going backwards in logs ruining what would be an awesome chart (*facepalm*) :lol:

As for the midrange, ya that looks like it's holding the torque friggin FLAT.

[shtbxr22]

Huge thanks to bren!!! :up: i love my car. :wub: and he also fixed my idle fluctuation, and it's smooth again. also, bren the 31 mpg was with your old tune. I'll see if i want to torture myself to try to outdo it. :lol:

[civic si hb]

HP curve is impressive, what is is like for the last 1000rpm??

TQ curve is just stupid!!! Making amazing TQ and just holding it like a champ!! Very Impressive Eric and Bren :)

Congrats

*** would a metal crushed wrx blowoff work of the spec B as a option?? (don;t know if they will fit or not)

[shtbxr22]

it pulls great all the way to 7k rpm. i'm gonna try to source a forge or turboxs full recirc bpv. I can use 08+ wrx bpv, but not 07 and earlier.

Ahhhhh....

I was just reading on here I think on page 2 about a wrx (09 or 10) also with a plastic BPV. I wasn't sure what the last year subaru used metal ones. I know the 06 and 07's do but not sure about the 08's???

[SicRedGt]

On stock injectors? Impressive.

[shtbxr22]

yeah, and i think he said they were only reaching around 90% too. :lol:

[Hero]

nice dude!

[98Wagoon]

:wub:


now I want a ride even more! :lol:

[shtbxr22]

let's do it!

[Berge56]

Nice numbers mang! TQ looks awesome.

[dubbz]

Very nice. BTW, the Mazdaspeed's and CX-7's use the same Forge BOV as the 08+ WRX. I got mine used on ebay. So maybe scour the Mazda forums for one.

[shtbxr22]

good to know, thanks!

[SicRedGt]

yeah, and i think he said they were only reaching around 90% too. :lol:


Thats it, selling the AP and going to see Bren.:D I'm at 98% IDC :eek:.

[civic si hb]

Yeah I need to do the injector mod real bad (for my 06 wrx) my duty cycle is slightly over 100%.... If I would of known this I would of done it before I went to get my protune done. I'm assuming once I raise my injector flow rate that I'll have to go back and get retuned again???

[BG @ BrenTuning]

100% doesnt equal 100%.

AFR target has a big effect on IDC.

[shtbxr22]

injector mod?

[shtbxr22]

right. chris' STI was around 130%, no? with that failing pump...

looks good! you got me beat on HP but Im a touch above that on torque in my VF52 spec.b I have a Perrin TMIC though. im only tuned to 19 or 20 psi too

That would be comparing two different things.

We will be having a dyno day 2 weekends from today for the Save the troops if both you and shtbxr want to do some same day pulls.

[shtbxr22]

we should try that. maybe i can source a non leaking bpv by then. :lol:

[shtbxr22]

wut?! :unamused:


somebody bought my buddies girls car that had a weak fuel pump.

indeed. I dont know what my schedule looks like quite yet but i might be interested. I have only run on the EFI Logics Dyno which tends to score lower than most...

Is he having a problem with the stock recirc valve? I am running mine no problems at the moment

Yes, it tends to hold sometimes, and not on others. Some have given up at lower boost like Kaizen's car.

hmm interesting. I havent noticed any issues with mine thus far but i wanted to do a GFB hybrid BOV at some point. Right now I just dropped 800 bucks on my pit bike, 300 on my boat and am about to drop 1500 on my supermoto for parts and labor so I will have to hold off on the GFB :unamused:b

[shtbxr22]

do not get the gfb hybrid. that's what i had on my car before, and it popped between 90% of the shifts. also, it had alot less spring pressure holding the valve closed than the OEM one. i recommend against it.

:orly: where arent these units holding from? if they arent sealed properly where they meet the intercooler thats not the BOV's fault thats the installers fault...

[Bu11dogg2]

all those mods and you still have a stock BOV?

[BG @ BrenTuning]

:orly: where arent these units holding from? if they arent sealed properly where they meet the intercooler thats not the BOV's fault thats the installers fault...

Sealed fine with oem gasket, replaced with stock bov and immediately got 25psi at the same boost level as the previous leaking 17.

You won't notice issues unless you start logging it. Hard to tell by seat of the pants feel.

[BG @ BrenTuning]

all those mods and you still have a stock BOV?

That's what I said when I opened the hood. :spin:

[CTATV]

all those mods and you still have a stock BOV?

yeah ive always heard it held a lot of boost. Jack and Chris at EFI said it was fine. im at 19.5 psi

[shtbxr22]

:orly: where arent these units holding from? if they arent sealed properly where they meet the intercooler thats not the BOV's fault thats the installers fault...


the spring pressure on the OE one is far stronger than the GFB I had.

[CTATV]

yeah I have the OE one

[shtbxr22]

oh, did i mention i'm a retard? 7 t-bolt clamps were loose. sorry to waste your time. they are tight now, so we go at it again....

[Seraphinwolf]

Hmmm... So wonder how I'll manage to hold all the pressure that builds from 86pds/min peak? :iam:

More on topic. So what are you holding at for pressure?

[shtbxr22]

i don't have a boost guage, so i don't know off hand. it must be maintaining better because seat of the pants feels way more consistent. i'll log it.....

[RCKSTR]

all those mods and you still don't have a boost gauge? snag one of those spt ones :spin:

[CTATV]

can always just plug in an access port and see the boost readings

[shtbxr22]

all those mods and you still don't have a boost gauge? snag one of those spt ones :spin:

I'm kinda picky with that. my mind does not process bar, it reads psi, and understands psi. I want one that will look good as far as fit and finish with the pod mounting, and it must read vacuum, and up to 30 psi. i have yet to find one like so.

That's an expensive boost gauge since he's allready Bren tuned.

fresh off the street...

Sorry for the shutdown at 6200 - i/c hose seemed to pop off. Great numbers, the car runs really well. Good job Eric. Most important part is the curve it holds 300whp almost to 6200 rpms, very impressive.

We swapped between a Forge BOV and stock one on the dyno and recorded the differences. For those who think it's not a necessary mod let the graph do the talking on the low end - forge would need to be tuned a bit for up top.

http://img.photobucket.com/albums/v412/brenwrx/SPECBstockbovvsforge.jpg?t=1284948955

[shtbxr22]

Oh yes, she feels fantastic. and The BPV will get the boot very soon. boost came on almost 300 RPM earlier with the aftermarket piece. thanks again bren, always a pleasure. :D

[Subyspeed]

Nice numbers !

[squeethebee]

That is only a problem with the newer style BPV's, right?

[BG @ BrenTuning]

ed

Correct, just the plastic ones.

[shtbxr22]

well there are still 2 different kinds of BPV. metal (STI), and plastic (wrx/lgt/xt). mine is plastic and sucks. i cant hammer the top to add pressure. but over 20 lbs i think is acceptable for a piece of **** plastic one. i'm not entirely sure of the pressure capabilities of the hammered metal ones. however i do know the GFB hybrid holds less than my **** plastic one. :lol:

[squeethebee]

Good to know!

My hammered one is holding 22.5 psi and loving it. I'm not sure if it is any different than GD BPVs though.

[squeethebee]

It seems that if it is metal (mine is) that we are set.

ed

[shtbxr22]

Update, got rid of that ****ty plastic BPV. Installed a full recirc TurboXS, and it feels so much better. holds more boost longer, and comes on sooner. also, more consistent and don't have to worry "how much power will it feel like this time" :lol:

[Subyspeed]

Good choice on BOV :up:

[CTATV]

Congrats. I did a forge BPV then something got messed up (not because of the bov and now I'm having bad knock correction and can't drive my car and my tuner is out of town till tuesday :(

yeah me too!

Dont know how the tune could have gotten messed up I had been running it for 13k miles on the car without issue... Im going to try some octane boost on the slim chance that its bad gas

[shtbxr22]

A little cold weather run without my clutch slipping finally:

It did. Turned out to be coincidence that I was playing with the BPV springs. I blew out the gasket between the turbo and the intercooler. Also had blown out all three gaskets in my Greddy catback :lol:




so what are the final numbers to the ground we are looking at here?


Very curious because I am running a very similar setup except I dont have pistons and I have TMIC

I'd have to get on an actual dyno to let you know. :shrug:

[BG @ BrenTuning]

It made 309whp / 353wtq on the Dynapack4000 with a fading clutch and plastic bpv only holding 13.5 psi to redline. Now it appears in his above log it is holding 15.5psi. So we should in theory see an increase in power before you upgrade to the new goods :).

Also, try a $10 vagcom cable for logging - the 2.0 openport on a canbus gives you those wavy logs because the rpms go backwards sometimes. I use 1.3u's to log those cars for most accurate results. PS LOVE YOUR BOOST graph - flat plateau.

Also the older version of virtual uses the .95 mustang and the developer said it was far too low - try the newest version which he has documented to be extremely accurate. :)

[shtbxr22]

16.11 psi at 6400 rpm according to the log. TurboXS BPV FTW!! :up: I'll see about the new VD software, and vagcom cable. it only took me 6 pulls with the stupid tactrix to get something useable. :unamused:

[BG @ BrenTuning]

lets re-run dyno it on winter fuel on the clutch / bpv - dynapack saturday? :)

[Bu11dogg2]

Nice work!!

What does the butt dyno say?

[Berge56]

lets re-run dyno it on winter fuel on the clutch / bpv - dynapack saturday? :)

nay!

just go FP red and blow it up! :rofl:

Whats lame is that it took so long for the aftermarket to make that style turbo. Its only been out sense 05

Nice numbers! That thing is a beast! Sounds mean! :D

Whats lame is that it took so long for the aftermarket to make that style turbo. Its only been out sense 05

Yeah, we get no love. :mad: luckily I have an FMIC that I can run both style turbos.

[arcadia25]

just go FP red and blow it up! :rofl:

if you rebuild it for me im down! :lol:

[shtbxr22]

will do!

[Simple Skillz]

I wanna hear how this car sounds now. Did you record a video during the tune??

[mdennett99]

Yeah, we get no love. :mad: luckily I have an FMIC that I can run both style turbos.

I have a FMIC waiting to go on, I just need to find a better turbo to run. Damn 5EAT

[arcadia25]

will do!

Ill hold you to that pal. Next time its tuned ill just push 25+psi, that should take care of it

Great numbers Eric. I am jelly bro.

[shtbxr22]

reason to get some new wheels if they explode. :lol: danka!

[BG @ BrenTuning]

Hows it feel Eric? You should do a write up of your thoughts both positive and negative versus the VF52.

[Simple Skillz]

The negative thing about his car is that there is nothing negative to say about it, I believe :D

[shtbxr22]

the only negative thing which I have gotten over is the lag. The power is silly compared to the 52, and maybe a 500 rpm difference between the power peaks, however having a steady rush to redline is so much better than falling of steeply after 5500. the thing feels like it could pull to 8k, but i'm not interested in that. also believe it or not, I got 30-40 miles more to a tank of gas. :shrug:

[hiprsha666]

I need to get rid of this vf52 myself.

[arcadia25]

because your car doesn't have enough power? :lol:

[hiprsha666]

Yes, precisely.

[arcadia25]

ah....indeed

[SCGT]

Eric took me for a, uh, quick ride in the HTA. Wow. She moves. Nice job Bren, and beautiful car Eric. I love your car.

[DHGurs]

Eric's car is definitely a beast.
Had a nice cruise with him and some of the guys last Saturday.
Love that HTA-68 power. It screams on the highway.
