apexjapan Posted September 29, 2010 Share Posted September 29, 2010 The lag's electronic, not in the intake. A throttle controller gets rid of it immediately. Improving the torque box/air intake will help performance, but if you added it to a car with the stock mapping, the pedal response lag will still be there (because Subaru put it there electronically).

Regards, Paul Hansen www.avoturboworld.com My 3.0R has SI-Drive so the electronic lag is adjustable. The biggest difference is the engine torque responded relatively quicker and stronger. My 3.0R engine has weak low end torque before, and so so low end torque after........ Link to comment Share on other sites More sharing options...
Sir_vq Posted April 9, 2012 Share Posted April 9, 2012 Kakimoto Racing makes a chamber for all N/A Subaru engines (2.0/2.5/3.0R) with a retail price of between $400-500 USD new. picture taken from the Kakimoto Racing website: http://www.kakimotoracing.co.jp/22-00_intake%28web%29/images/chamber_00.jpg Box from Japan http://img46.imageshack.us/img46/1952/pict0002oz.jpg http://img46.imageshack.us/img46/4919/56415777.jpg http://img46.imageshack.us/img46/4932/56372640.jpg The LHD version has that A/C line (red circle) This line does not appear on RHD version, so the air chamber needs to be raised about 1 inch to avoid it. http://img145.imageshack.us/img145/5923/97596087.jpg http://img205.imageshack.us/img205/462/img4406m.jpg http://img524.imageshack.us/img524/4051/img4410.jpg JDM air chamber with tuned pipe for smoother air flow http://img41.imageshack.us/img41/9319/intakebox.jpg LHD versions had their tuned pipe removed (can still see the bracket holding the pipe inside) Due to the A/C line. http://img693.imageshack.us/img693/5636/img4413x.jpg Factory LHD air chamber (dented to avoid LHD AC line) http://img515.imageshack.us/img515/8661/img4414.jpg Dent on the back to avoid A/C line Impression: Pro: Much better initial throttle response, finally the flat six roar instead of that electric wheelchair whine. Bad: Not a perfect fit for LHD model due to A/C line, a little too much resonance in the roar (trying to fix that right now...stay tuned) Gets pretty hot under the hood. what's the diameter of that thing? in kinda reminds me of my 'jun' whale intake from Honda days Link to comment Share on other sites More sharing options...
Leviman Posted April 9, 2012 Share Posted April 9, 2012 Looks like a nice piece of rice to me. And as for the throttle response comments, the 'lag' is not in the throttle, it's in the fact that we have a 2.5 litre four cylinder pushing around a 3300 pound car. I've logged my car and to WOT there is about 20ms delay between the pedal and the throttle plate. That is almost nothing. Link to comment Share on other sites More sharing options...
PNG410 Posted August 1, 2013 Share Posted August 1, 2013 So has anyone one got some new info on the intake chamber from kakimoto? some real facts cause from what they are telling me from http://www.japanparts.com is not worth me risking the pruchase, any dyno sheets with the exact gains?

pachilla Posted August 1, 2013 Author Share Posted August 1, 2013 Kakimoto has a dyno sheet available on their website...no peak power gains, just faster torque response (torque arrives slightly earlier), but you do feel it...... Link to comment Share on other sites More sharing options...
PNG410 Posted August 2, 2013 Share Posted August 2, 2013 yea people are saying it gets heaps hot and stuff too.. i want to buy it but i dunno im still undecided.. Link to comment Share on other sites More sharing options...

This box does quicken throttle response somewhat regardless of the SI-Drive mode setting. Link to comment Share on other sites More sharing options...
saffarco Posted August 4, 2013 Share Posted August 4, 2013 I used this on my h6 for 1 year almost. I tuned her via XRT, I noticed that when I floor it on the 3rd gear, A/F becomes lean then starts to be ok. That's just from memory, I think that explains the initial response. I would say: NOT worth the price Link to comment Share on other sites More sharing options...
