I recently purchased a cherry Nebula Grey 2015 CT200H with only 13k miles on it. I love it, but was not impressed with the acceleration, or lack thereof. I was bound and determined to improve on it without resorting to a CAI. My reasoning is they make too much noise. Why not work with the OEM air box and air horn assembly. I have been doing it a little at a time, kinda like the scientific method. Tonight I was coming back from a Birthday dinner, and was able to get out on the highway after hours. What was bothering me, and everyone else who I read on this and elsewhere is the lazy acceleration. That ended tonight. I almost can not believe it. Im not going into exactly what Ive done just yet. And there is more to do, Im just posting this in hopes there are others that might be interested in upping the performance and fun of driving this fantastic little car. Here's the best part, its actually as quiet or quieter than stock!
Let me give you a little backround on me, Im a cylinder head specialist for the the last 40+ years, so I know a thing or two about improving flow in motorcycle heads for racing purposes. This was just a little project to see if it could be done, and Im here to tell you that its most impressive, and I still have the stock air filter in yet. Im sure as you read this your saying to yourself it sounds too good to be true. Around town its definitely better, but where it really shines is on the highway. I will be releasing info on what to do, and im sure anyone interested in doing it themselves can probably guess some or most of what there is to do. Its the last piece I got really lucky on, and I have to get that manufactured to spec. Once everything is in place, highway driving and spirited driving will be making you smile, it did me, that's why I'm posting this. This is my first ever post here, and I hope Im not crossing any line with the moderators, but I was so impressed, I just had to tell someone who might care.

Modified the airbox to get more flow into it, ie took out sharp edges. Took out the charcoal mesh filter above the replaceable air filter, and the last trick, the one that makes it all come together, Im saving that info...I will be offering the last piece for sale once I have them in stock. But trust me, it will be so worth it...the more I drive with this thing in place, the more it makes me smile.

How difficult would it be to install/modify? Necessary to take it to a shop with minimal car modifying experience? How much faster does it accelerate? How much does it impact mpg?

Sorry for the blast of questions - I'm interested!

I wish our cars had a way to run on Otto cycle when we wanted them to
I know the Tacoma can run on both cycles. We should be getting a LOT more power out of a 1.8

I do not have dyno numbers, but I will be using an accelerometer to test real world performance. Right now I have the prototype installed, and it works really well. Im in the middle of developing the production part for the improvement. I hope to have the pieces done next month. Once I have more info, I will post it. Its early yet, but I know this works. Is it turbo like, not on a bet, but it is much better. Please bear with...this is a real thing.

really curious about this...are you playing with MAF scaling, new exhaust flow, intake manifold ???...the ECU on these is too smart for its own good, excited and hopeful to see if you've found a way to trick it into making more powah baby.

I bet it's one of those little electric fans on the intake. those have been proven to be garbage, but... we aren't limited to a dinky 12v fan like most cars. so maybe if it was one of these it could possibly show some real numbers?
