*****Fast Intentions "Twin Turbo Kit" is here*****

TerribleONE

We pulled the filters off completely on the dyno to see if we picked up or lost any power, however there was no difference. I am sure we can do some runs with the bumper on if there is a speculation that this is inflating results. Also the car did go 11.8 @ 124 (with the bumper on). That trap speed is a very good indication that the car is still making the stated power levels.

This whole filter talk about being restricted where they sit is a bit rediculous. I mean its not like you force air into the intakes. They create a vacuume. They dont really need that much space. Just as long as they are not sucking in hot air really is the only concern and where they are positioned they will not do that.

Look at the BP kit. He has just one filter on there in a crammed location. These two filters will be just fine.

Great input! If this was a NA application it would be much more crucial. What is more important is how straight of a shot it is from the filter to the turbo. Large bends combined with large distances can greatly restrict. In the case of our kit it is as close to a straight shot is it is going to get.

Thanks, Tony

I wasn't saying anything about the Filters being on or off, but about the front Bumper being off. On a strip is one thing because the car is moving, not on a dyno where its sitting in one spot. Yes, I see blower fans, but those are focused for radiator/intercooler cooling.

Right they do, not questioning that. But what happens when the vacuum is greater than the volume of air that's able to fill the space since there's not a direct opening? That's the only thought.

Of course, not commenting about the flow of the pipes Tony, just curious about the placement of filters in terms of available airflow.

With the front mount intercooler I don't think you have many other options as far as placement. However I do see where you are going with it. We will be back on the dyne soon enough.

Agreed, that does limit your placement as long as you wanna keep it out of the engine bay...

Just something that crossed my mind, not trying to slander your build or Tony's epic product.

Didn't take it that way at all You have one nice 370 yourself.

Nowhere near your power potential though...


One day. It's down to FI or BP if he ever makes a 7AT kit for my boost.

No. This point is invalid. Look at my ridgeline or any other oem panel filter airbox with a decent amount of power. The box is completely sealed off except for a 1" by 8" slot intake duct. The twin cone filter area has multiple times this amount of available free air space. This should be looked at as a zero cost of concern.

Missed a few pages, not sure if anyone asked this but is this with a hi-flow cat? Says "full" 2.5 so i wasn't sure if there was a downpipe or both?

We have not tried this setup with a HFC. We ran the car on stock cats, as well as a full 2.5" setup (downpipes, exhaust)

Perhaps I don't understand your concern then. But a better example is something like the stillen cai. It's box and positioning pretty much choke it out also but I dyno ran it with the hood open to free up any air and with it closed where its in a pretty tight cage. No difference.

The vacuum effect is weird. That's why when you are shop vacuuming something even extremely light you still have to almost touch it to get it to suck up.

I'm not trying to say you had a silly question. I'm just saying that to put it to rest as a question regarding the kits engineering.

Another dyno video for you guys

Sounds so sick,silky, smooth and rough all @ the same time.

Not sure about what's with the "in-depth" intake issue here. All The TT's that are designed this way seem to have the filters sticking out on the sides of the intercooler. If lets say, you tried to design some piping to get more air to the filters. I think the next worry would be hydrolock? Not to mention their would most likely be a much unneeded new curve in the pipe.
If airflow is that much of a concern? What has to be changed is not the intake designation... But the front fascia. The Stillen and Fujimura Body kits would quell airflow concerns.

Good shyt FI.
