Installed the TB, at first it's hard to tell the difference. At approximately 20 miles after the part was installed, I felt it was easier to shift smoothly. Placebo effect? Could be, but it only has gotten better since. It is not a huge difference, but somewhat noticeable.

I feel that I can let go off the throttle in gear and if I step on the gas again it will start picking up quicker than it used to.

My thoughts are that once you let go off the throttle body, the air velocity going through the TB slows down, but since the TB is now larger, it is essentially easier and quicker to speed up the air (more volume from where to suck from). I would relate this to trying to drink water through a straw off 2 differently-sized perfectly-sealed containers.

Car feels a bit faster (barely) but what I really like is that if I suddenly decide I want to pass a car and step on the throttle, the car will respond a little bit faster (even in higher gears).

We have a learning ECU that should account for the extra amount of air.

I wouldn't say it makes a whole lot of difference but the results seem to justify the price.

~$195 from SoS for AP1

Approximate mileage right now = 120mi.

Of course, Chris, Brian, Josh, and Jeff, the guys at SoS are always awesome and helpful.

 

thanks Manuel! Let us know your long-term thoughts on it

 

do you need an ecu to use this to the fullest? Can i just install it and feel differences?

 

I don't fully understand this mod. Spoon has one that's tapered too. If the port on the mani is not the same size, it wouldn't make much of a diff.

now all u need is 3 more

 

Boof the port size of a stock intake manifold is 66mm (i believe could be wrong). The stock port size of the throttle body is 62.5mm. When we have ours bored they are bored with the factory taper and factory elipse(sp) meaning the throttle body is not a perfect circle it has somewhat of an oval shape to it and we keep that the same. We open ours up to 66mm which matches the factory intake manifold perfect.

If you have anything larger than that YES you need to port match the manifold to get any benefit out of it.

 

Thanks for clearing that up.

Can I bring mine in? I had no idea this was that mismatched to the port. I must take care of that

Why is the DBW $50 more?

 

because you touch yourself at night!
because it is newer, so they can charge more... duh?

 

thought i would bring this back up.... i just picked up mine today. its installed but i dont have my intake attached yet cuz i had to go to work. its really nice and pretty! whats the update on yours manuel? still like it?

thanks sos
