a.lim Posted February 12, 2008 Share Posted February 12, 2008 hows the performance compared to the k&n? Link to comment Share on other sites More sharing options...
BoxerGT2.5 Posted February 12, 2008 Share Posted February 12, 2008 That looked fun. Stock tranny still running strong? I think the AVO is a great product at a great price, and is quieter than the K & N. Tranny is fine. OBAMA......One Big Ass Mistake America!

Infamous1 Posted February 13, 2008 Share Posted February 13, 2008 hows the performance compared to the k&n? I have been tuning my Typhoon and I will say it is very consistant and hardly ever resonates. The main reason most go for the AVO is because it slightly bigger diameter allowing it to easily accommodate larger turbos. I have no experience with tuning an AVO however a local did express his dislikes about the design. I personally would go for the K&N solely because it is CARB legal in CA.

They should be by now, I know the 05-06 definately are. Just be careful the CHP popped me for an emissions violation last Summer, had to go see the Smog ref up at Chaffey College and all. If your not tuning the intake it really is only a concern for your tuner. Link to comment Share on other sites More sharing options...
05pearl Posted February 26, 2008 Share Posted February 26, 2008 You need to understand why. Flowing 240 or so g/s (VF40) the stock airbox is not much of a restriction. Flowing 300 or so g/s (medium sized turbo) the stock airbox is a significant restriction. Flowing 400 or so g/s (large rotated mount).............well, I doubt you would flow that much on the stock airbox. It doesn't really add power, it is a restriction, just a lot more a restriction with a bigger turbo. Does this mean that the stock airbox will not flow more than around 240g/s (even with a larger than stock turbo)? The reason I asked is because when I logged; the max MAF I saw was about 246g/s (at 5200', 12.3 atm pressure) with my 20G. I assume if your numbers above are accurate, the stock airbox is really limiting my turbo? Link to comment Share on other sites More sharing options...

I assume if your numbers above are accurate, the stock airbox is really limiting my turbo? The stock airbox will flow above that, for sure. It starts to become a sizable restriction above that amount (give or take a bit). For a 20g you are leaving a lot on the table with the OEM airbox.

05pearl Posted March 8, 2008 Share Posted March 8, 2008 ^^^ Still waiting for a time to tune for the AVO intake. Not changing anything else except the intake, when I install and tune for the new AVO intake, will it result in a broader area under the torque curve vs. the stock air box or will it simply raise the peak value of the curve?

edmundu Posted March 8, 2008 Author Share Posted March 8, 2008 It'll help all over..... IT allows the turbo too more easily suck in air, resulting in better response & power. Link to comment Share on other sites More sharing options...
Legacy_GT_Pilot Posted March 10, 2008 Share Posted March 10, 2008 How did your tuning go? I'm about halfway through tuning my AVO and so far I'm impressed. My MAF values are significantly higher than stock through the closed loop portion of the range. If this improvement holds up top, I will no longer be pegging my MAF and will have some headroom to spare. Dave I will be tuning the AVO this weekend... ________ Dennie Link to comment Share on other sites More sharing options...
SSpeed Posted March 25, 2008 Share Posted March 25, 2008 I have had 3 different exhausts, and the current one uses modified stock cans, and I feel I am not leaving more than 3-4whp on the table. If even that much.... How did you modify the stock cans? I was looking to do the same thing, but the tiny stock 1.5" piping goes most of the way through the muffler....

edmundu Posted March 25, 2008 Author Share Posted March 25, 2008 ^^^ I cut open the inlet chamber side, peeled it back, and then drilled 8-10 3/8" holes into the pipe. Then sealed them back up with a patch panel and muffler cement. This mod allows the exhaust to remain docile under part throttle, but under WOT, the backpressure builds to where the exhaust just goes out the drilled holes and out the muffler outlet, mostly bypassing the 2nd rear chamber.

I figured it was something like that... how well do you think it works? Would you go through the trouble again? Having the 2.5" AVO Y's go in to the stock 1.5" muffler inlets just has me thinking... Two 1.5" pipes have the area of a single 2" pipe... I like the quietness of the stock cans, I just can't get over that reduction... Link to comment Share on other sites More sharing options...

Guest Posted September 25, 2008 Share Posted September 25, 2008 Bumping this thread as the info is relevant. With edmundu we installed the AVO intake on my car Sunday evening... Should be piece of cake, right? Wrong. The screws for MAF sensor AVO supplies with the intake are absolutely wrong for the application. Provided hex head screws (with oddball 7mm heads) cannot work because the heads sink into the holes on the MAF sensor flanges. You cannot get socket or wrench on them. Actually on one side the screw would not go in at all as it hits MAF housing. FAIL. Luckily edmundu had some washers and grommets and we rigged up a temporary ghetto fix that worked (otherwise it would prevent us from the scheduled road tuning). Picture below shows the included hex head screw and a a Philips replacement screw I got later. What was need was M4 x 12mm screw with 0.7mm thread pitch. On a positive side, edmundu noted that AVO upped quality of the band clamps plus they have normal 8mm screws and not 7mm. Btw, his version used the stock tap screws to secure MAF. The threaded screws are an improvement, just too bad correct screws were not included. Moral of the story - never assume an aftermarket part will fit and do not plan to install it on Sunday evening without checking fitment first Link to comment Share on other sites More sharing options...
apexjapan Posted September 27, 2008 Share Posted September 27, 2008 My apologies for that! We did get a batch in that had the wrong bolts, and I was replacing them all in the kits at that time. I must have missed one though, and sent it out with the older bolts. I'm getting another shipment in from Tuesday, I'll check them all twice!

Guest Posted September 27, 2008 Share Posted September 27, 2008 Yeah, I figured I am the "customer fatale" already! On a positive side, AVO tmic saved my install since Perrin timc absolutely had no chance of fitting. Link to comment Share on other sites More sharing options...
Bbc84 Posted October 2, 2008 Share Posted October 2, 2008 do you think the car will be safe to drive 30-40miles to a shop w/ AVO intake installed and Cobb Stg 2 map w/ supporting mods?
