Another piece to the puzzle. I spent a few hours swapping in a MAP o2 elim downpipe last night while spaz was doing his brakes. We got sidetracked a few times due to stuck brake pad pins but we were mostly done by my anna-imposed 11pm curfew (gotta get up early for work and the pups go crazy every time I come in for keys, wash hands, etc etc), we had to go till about midnight to finish everything up but she was pretty understanding due to the fact that she was swooning over how beautiful this piece is:

(my little beagle jill in the background)










Tennis ball rolls all the way through this thing no prob (I was curious about the flex section):




Next to the stock 'o2' housing and downpipe:


This thing is big, getting it in place was not hard but unfortunately I did scratch the ceramic coating just a bit on some of the heat shields on the firewall Without the flash it's tough to see, but there it is, gah! When you look down at this thing from the top it is kinda impressive how BIG it is. Fitment was absolutely perfect.





Fired it up for a leak test and around the block quick before bed, the first real test drive was on the way into work this morning. I drove Anna (like most days) and kept it pretty mild until I dropped her off. Most noticable improvement is part throttle in the 2500-4500rpm range, the car feels fantastic! The BBX felt a teensy bit doggy on the stock o2/downpipe but I have done nearly zero tuning to really try and get it more responsive because I knew this downpipe was on the way sooner rather than later

I threw on the logger and did some more aggressive driving and 3rd gear WOT pulls after I dropped the lady off and WOW seat of the pants feels great! Butt dyno immediately said 15whp up top, so after playing around a bit I went to one of my usual straight, flat spots and did some dedicated VDR pulls.

Always remember to take these with a grain of salt, it's not a true dyno but as best of a back-to-back as I could do!


The low-end makes no sense to me, its obvious that some tuning is needed from my tweaked stock turbo tune so I'll be addressing that in the future, but holly *****! +25whp@7000rpm! I am extremely happy with this thing and would recommend it to anyone. The fit/finish/quality is just top notch.

Next week the car will be at DB Performance for a power tune

 

Wow. Nice piece. Glad everything is coming together.

 

the low end is because your spooling up slightly latter because of the bigger 02 housing

 

Idk, timing is all goofed up down there too, this is still only a rough tune, no change from before. I'll mess with it, it's only like 12-13* at 7k rpm, she's got a lot more in her!

Hrm, Aquamist or tubular header next? Decisions decisions.

 

Aquamist

 

Gah tephra you're a bad influence!

 

I vote header then E85 Man up scheides in the words of Jim.

 

dont forget noize that Blacktrack ran his stock block at over 500 whp for over 10k HARD Track only miles before it let go.

 

One motor doesn't make for much of a statistic. I was in murlo26's car when it popped at a similar power level. Which is more relevant?

Are you suggesting that a street car should last 20k miles? 50k? It's still not long enough, imo. Torque anywhere in the 400's (Dynojet) is playing with fire on a stock bottom end.

 

Neither really matter, on this setup if I'm lucky I'll hit 375whp/330wtq pump gas and no alky no e85 for a while so I'm not too concerned. Just looking for a decent powered fun DD, uber reliable. Should be able to drag, autoX, or big track it now w/o too much concern, but the primary goal will be to just put miles on it and drive the thing. Downtime sucks.

If I do more mods and start making 420+whp I might start thinking about drop-ins but I kinda doubt it. I made damn good power on my last car and I'm not afraid to push this one a little its all good fun.

 

I'm with you on this one! I rode in a IX that's aprox. as powerful as my IX was and although it felt fast/fun, I don't miss the constant issues one bit.

 

Got the new setup tuned today! As usual, Shane couldn't push timing much as beaterX is kinda a ***** and/or we just don't have very awesome pump gas around here. Shane said that the car *loved* timing in that it would make decent gains for every degree added but it wasn't always liking it. We ended up running only about 13° up top, really a lot less than I expected, but the car feels fantastic now.

It rolled in at 321whp @27psi tapering to 25-25.5 and left with 346 @ 28 tapering to 26 and a crap-load more midrange than it came in with. More on that in a sec.

Dyno Dynamics numbers, 1.0CF:


Shootout/Dynojet numbers:


28psi peak, tapering to 26. Here's where a BCS might help a bit up top, but my FMIC is overtaxed as it is, so meh. Both Bryan@GST Motorsports and Chad@CBRD said that every psi over 25 yields great great gains on this turbo and that 28 is a great target for pump gas.


Nice and rich to help prevent knock


Here's the best! When I first bolted this thing on, it was at or below the torque of my stock turbo. NOW with the tuning love from DB Performance, I went from 282wtq on the stock turbo to 311wtq with the BBX! Granted, I also have the MAP o2 elim downpipe on the car now as well but it really doesn't matter, the new setup lost some spool but I'm up torque and power bigtime!

+68whp/+29wtq


Lost about 800rpm of spool, but this turbo is rated at 58lbs/min. Seeing 25psi by 3900rpm is pretty damn good imho.


I'm extremely happy with the new setup! So smooth, decent power, and should be very reliable. Time to go to the track and see if I can get this bish into the 12's! I've got 2000 miles on the ACT 6-puck and 1000 miles on the BBX already; I'm ready to just keep driving this thing and keep having fun!

 

you should run leaner...

evox's really don't like less than 11.4:1 - and will knock MORE with richer fuel.

I would be tempted to see if you can run 11.5:1 from 5600+ to see if you can add some more timing...

 

Had it there to begin with and it wasn't helping things. I'll try it in the future but for todays tuning session where we had it made the most power the most reliably. Maybe its particular wideband calibration, maybe just my car, idk but it is what it is. Once I get a better FMIC I think it'll be worth trying.

 

You must live in a safe neighborhood. Glad that was still on your back step when you got home.
