Re: GheyrodX - bigger, fatter, gheyer!
I think he's somewhat crazy too but I ain't hatin. End of the day if he hates the BCS and/or accessport he can sell it and be right back where he started.

Re: GheyrodX - bigger, fatter, gheyer!
MAP FMIC finally installed!
http://www.dsmstyle.com/photopost/da...1106001128.jpg Fitment of this thing was perfect. Since it was made for a 2008 and I have a 2010 (different intercooler brackets) I had to drill a single hole and use a self-tapping screw to secure it to the chassis which was ultra easy. It's mounted rock solid, is even, and almost exactly centered. Thanks to Tom and Armando for stopping over to lend a hand :) |
Re: GheyrodX - bigger, fatter, gheyer!
Yup it looks great and fit just as well. Always happy to lend a hand when I can. :D

Re: GheyrodX - bigger, fatter, gheyer!
^Yup. I saw this in person and it looks absolutely perfect. I wanted to steal it from Kracka, lol!

Re: GheyrodX - bigger, fatter, gheyer!
Lets see, where to start...today was a pretty damn epic day. I honestly don't think I've been this excited about car stuff in a LONG time.
Quick back story: Ever since I got GheyrodX tuned back in July I haven't been real happy with it. It drove really well, perfectly smooth, etc., but it was really down on power (especially torque) compared to where it "should" be. What really made that apparent and when I realized I needed to do something is at the NTEC dyno-day last month; my car was getting owned by even basic stock intake/stock catback X's. AFR's were spot on, it took a little timing but not much, and I was just sick of dicking with it. Last weekend we got the MAP FMIC installed, but today was the big day. First I started it off by installing a Grimspeed 3-port BCS then limped it to Cobb Tuning staying out of boost the best I could. Today's plan: 1. Completely retune the car with an Accessport 2. Install MAP o2 eliminator downpipe 3. Retune again for hard back-to-back data on the downpipe 1. Prior tune (stock FMIC w/MBC) vs. Cobb tune (MAP FMIC w/3-port): http://accessecu.com/dyno/graph.php?...rgb2=204000000 http://accessecu.com/dyno/graph.php?...rgb2=204000000 2. Downpipe install (please note the care they took, covered everything possible to prevent scratching or damage): http://farm5.static.flickr.com/4108/...d2bcea65_z.jpg http://farm5.static.flickr.com/4124/...5418df35_z.jpg http://farm5.static.flickr.com/4104/...190baca1_z.jpg 3. Stock o2 housing & downpipe vs. MAP o2 eliminator downpipe: http://accessecu.com/dyno/graph.php?...rgb2=204000000 http://accessecu.com/dyno/graph.php?...rgb2=204000000 SOLID GAINS!!! To those who say they're worthless on stock turbo/pump gas setups...eat it :) Final runs dyno video: http://www.youtube.com/watch?v=gHcADsKHoyo&hd=1&hd=1 |
Re: GheyrodX - bigger, fatter, gheyer!
Woot! I'm shocked the 3-port and AP made such a difference. The o2 downpipe is definitely worth it on any setup, super nice to see a before/after on the stock turbo. The piece is so nice it'd be hard for it *not* to make power over the stock question-mark o2 housing!
Wonder where this thing would be at DB now, its gotta be over 300whp and 320wtq. Fantastic numbers for simple bolt-on parts! Finally teh gheyrodX will be able to hold its own on the streets of dall-ass? :D Congrats! |
Re: GheyrodX - bigger, fatter, gheyer!
Such an epic post and you failed to mentioned that your good buddy Rmondoh took awesome pictures for you but most importantly, you didn't comment on the tune/ride on your ride back home!! EPIC FAIL! :p
Pictures of the day can be seen here :) http://www.flickr.com/photos/rmondoh...7625377859768/ Now for some random comments on things throughout the day: 1. This is for Scheides' comment above regarding the 3port and AP. Kracka thinks that the reason why the gains are so drastically different is because the 10's ECU just DOES NOT like MBCs. He told me that he fiddled with boost, timing, etc and he just couldn't make it any better. 2. Took a picture of Kracka taking a picture of the AP. I'm sure some of you guys got a text saying "WTF is this thing?" followed by a picture. Well, now you know the source of that text. :) http://farm5.static.flickr.com/4021/...b7d71936_b.jpg 3. As for MAP's o2/dp, there needs to be a slight tweak on it. The o2 bung needs to be moved to the original location. The place where it is now is not very good. Here's some pictures. http://farm5.static.flickr.com/4152/...8f7b213b_b.jpg (You can barely see the bung behind the bolt here) http://farm5.static.flickr.com/4107/...43450bb1_b.jpg http://farm5.static.flickr.com/4110/...90274cd1_b.jpg http://farm5.static.flickr.com/4131/...f9195907_b.jpg 4. Now I fell asleep watching TV ~10pm and just woke up and found that this thread was posted (along with a text from Kracka). Having read and looked at the graphs and having the adrenaline high wear off so that I'm thinking more clearly now, I'm not sure if the o2/dp is worth it. Don't get me wrong, I love that it made gains and I was just as excited as Kracka to see the results, but we need ONE more test to see what the real difference is. Hear me out... Discussing (well listening on my part) with Chris@Cobb about the o2/dp, Cobb says that the restriction is not the o2 housing but the downpipe portion itself. That is the reason why Cobb only makes the downpipe section and not the entire o2/dp. Looking at the gains between stock o2/dp vs MAP's o2/dp, I wonder how much is actually provided by the o2 eliminator and divorced design. The gains are small enough to where going from the stock downpipe diameter of 2.5" (or whatever it is) to a full 3" MAY BE the difference that provided the gains and not necessarily the o2 elim part. MAP's o2/dp does have a wider diameter downpipe as well and the whole thing really is a 3" pipe from turbo outlet to testpipe flange. However maybe the o2 housing bellmouth flows just as well given how it was designed. Just something to consider. Maybe Cobb DID do their research correctly. :) Thoughts on this? Perhaps Chris@Cobb might be willing to do another super awesome deal to someone willing to lend their car for some testing. Hmm... |

Drive home impressions: WOW! The car is a whole new beast now, can't believe I've left this much on the table since July! The car runs awesome smooth, but it really kicks you in the pants now when the turbo gets going. It's reminding me more of the original Gheyrod :) 1. That's my theory at least. Cobb seems to agree. Calvin did a great job with the boost control via the Grimspeed though. My favorite part is at peak torque though, nearly identical boost and AFR, but +59 wtq!!! That is such an incredible gain it's insane! 3. Agreed. It is rubbing on the chassis at idle; very stupid placement that I will be talking with MAP about. There is no reason not to locate it with stock orientation at 12 o'clock. Other than that though, what an awesome piece! Perfect fitment and clearance everywhere else. Solid gains across the entire curve, torque and horsepower! I was quite surprised at how much tweaking the tune needed to compensate for the o2/downpipe. 4. I too am curious about this. My guess is we could talk Chris @ Cobb (Plano locations manager) into doing this test on your car. Their downpipe and a few quick tweaks to your tune and we'd have solid answers vs. stock and vs. my o2 elim dp. I'm all for any type of hard dyno data possible and would be very interested to see the results; might as well be on your car :D |
Re: GheyrodX - bigger, fatter, gheyer!
WOOT!
Congratulations Chris, very impressive, those are some solid numbers! I bet this car feels completely different now. Enjoy this thing! COBB FTW! Just to share, the AMS o2/dp addition on my car, required a a bunch of retuning as well to keep the boost control in check. |

Re: GheyrodX - bigger, fatter, gheyer!
I think there is something to be said about position of the wastegate flapper and the power difference. I need to find the overlay, but gheyrodX and beaterX had nearly identical setups save for the wgacrank mod and beaterX blew gheyrodX out of the water in torque/midrange and just a wee bit up top. I'm guessing something with how a MBC actually delivers air to the wga vs how a BCS does is what causes some of these gains: the MBC may cause a bit more open/closing of the wga and thus hurting flow. Doing the wgacrank mod with a MBC must help keep the wga in a more optimal position.
I'll find that overlay if I can, or do you have it hughes? As far as the downpipe/o2 elim goes I think I have two big beefs with the stock setup: 1) weight. The stock o2 housing specifically must weigh 30 pounds itself. Just redonk! 2) It is a tight 'questionmark' type bend that I think on a stock turbo is mostly fine save for the outlet. IIRC the stock o2 housing necks down right at its outlet. On an aftermarket, stock-frame turbo I think there is no question that the stock o2 housing (even with a 3" downpipe) would not be adequate, especially if you were running alky/e85 trying to push the setup. I saw huge gains just on pump gas with the BBX. Overall I am just pumped you have the car to a whole new level. Good thing you're in a place you can enjoy it, there's almost a foot of snow on the ground up here! |

stock o2 housing & downpipe: 14.8 lbs. MAP o2 elim dp: 8.2 lbs. Thanks Scheides! I too am so freakin' pumped with the car now it's insane! Driving it really is a whole new machine. |
Re: GheyrodX - bigger, fatter, gheyer!

Logically, I would agree with Scheides on going with a bigger turbo would mean you have to go with a new o2/dp. However, for a stock frame turbo...I'm not so sure. Despite the test, I still want to believe that an o2/dp would work better even on a stock frame turbo as opposed to just the downpipe. I just looked at AMS' website and they claim a 15whp gain over stock with their o2/dp. Chris picked up 9 whp so 15 may be possible with a bit more aggressive tune. I think the gain with any o2/dp or just downpipe will fall in the 8-12 whp range (just my personal guess :)). I'll have to get a hold of Chris @ Cobb to see if we can work out some type of deal. I'm definitely interested in what their downpipe may yield by retaining the stock o2 housing. |
Re: GheyrodX - bigger, fatter, gheyer!
Congrats Kracka...happy to see you are getting the car up to snuff (well your likings :))

Re: GheyrodX - bigger, fatter, gheyer!
I did a 1st - 4th gear pull leaving the airport tonight and I seriously just about pulled over to have sex with the car...it rips! Stock turbo/pump gas FTW!
BTW, they're installing E85 pumps at a station that's on my way to work. Not hinting at anything, just sayin' ;) If my stock fuel injectors/pump could support E85 on my current setup it could be fun having alt. maps. Cobb's standard setup for E85 X's are DW850's and an in-tank Bosch pump. I also popped a CEL (P0140 - rear o2 sensor) on the drive home and within 5 minutes Kevin/Calvin had a new ROM in my inbox...not too shabby considering it's Sunday and the Cowboys game is on. |

Re: GheyrodX - bigger, fatter, gheyer!
Figured I'd post some favorites from my picture set for everyone even though a couple were posted already!
Hello shiny ceramic coated MAP o2 elim downpipe! http://farm5.static.flickr.com/4148/...aba63a49_b.jpg http://farm5.static.flickr.com/4133/...554ac2ff_b.jpg This is Chris taking a picture of some weird alien device in his car. http://farm5.static.flickr.com/4021/...b7d71936_b.jpg If only that GT-R would have been white... http://farm5.static.flickr.com/4124/...5418df35_b.jpg Who can forget the antics of Tom http://farm5.static.flickr.com/4092/...8d1e9da6_b.jpg And of course the post would not be complete without me showing off my car next to Chris @ Cobb's car :) http://farm5.static.flickr.com/4133/...47b62142_b.jpg |
Re: GheyrodX - bigger, fatter, gheyer!
I'm picking up catback #3 for the car today...
|
Re: GheyrodX - bigger, fatter, gheyer!
Let's hope that fixes your rattle issue! :)
|
Re: GheyrodX - bigger, fatter, gheyer!
Cobb catback installed! Fits much better; a lot more clearance plus less bends and non-baffled/chambered muffler.
|
Re: GheyrodX - bigger, fatter, gheyer!
Cobb is to Kracka as Buscher is to Scheides. :D
