Intakes for the Twins...Opinions please...
 
Here's the most recent setup on the R1. Give your opinions on the intakes ladies and getns. :icon_tup: :icon_tdow :Wconfused

It looks like you are missing a nut on your passenger side strut brace.

Mahjik 07-26-08 01:25 PM

The intake is fine, but you'll never to cover the upper hole in your IC ducting.

Would you suggest a breather??? What is the disadvantage to plugging that hole???

Ugh, I hit edit post rather than reply. :(

Sorry, that shouldn't be "never". That should been "better". You should cover that hole to force as much air as your can through your IC.

RLaoFD 07-26-08 02:05 PM

:lol:

and +1 on covering that duct, the more air into the stock, inefficient intercooler, the better.

Natey 07-26-08 02:38 PM

Did you buy your intake pipes off of eBay, and the lower one didn't fit? Sounds familiar if so.

Nice FD, BTW. It looks clean in that 5th pic. :) Now wipe off the upper mani!

staticguitar313 07-26-08 02:41 PM

My opinion is that your username wins, and so does your intake for a budget endeavor :)

TpCpLaYa 07-26-08 02:49 PM

i think its also a good idea to get some small cheap piece of sheet metal to put under the intakes to help shield a little bit of all the HOTT radiator heat that is right beneath the filters

It's a turbocharged car. Cooling the air before it goes to the turbo(s) is pointless.

Dream Theater 07-26-08 03:07 PM

hahaha thanks. Ironically, the intake parts are from Autozone and the K&N's are from Advance Auto...Long story but I was tired of looking at the stock airbox and I wanted to change it up a bit. Will definitely fab a peice of metal to go under those filters. Any others suggestions guys thanks!

-D-

And yes I'll wipe it down. lol

Good point here, going through the turbos, the air will be damn hot anyway.

BUT: the cooler the densier, so your logic is not 100% right.

More density means more O2 means more power.

This is the stupidest thing I've read on here in the last few months.

A turbocharger doesn't heat the charge to some particular and unchanging temperature regardless of what it is being fed.

heidihi 07-26-08 06:42 PM

colder the air going into the turbo should still be going out cooler than if it were warmer going in.. granted it will be heated more going out regardless but it wont be so dramatic..

Dudemaaanownsanrx7 07-26-08 07:42 PM

the incoming air is more important with the stock, or any undersized intercooler. Which he is running. A large intercooler probably wont make a huge difference as it will cool it within a few Celsius of ambiant air.

LoL...that's the first thing I noticed too!

7dust 07-26-08 09:03 PM

Tell us how how the intake performs?

Whats the Butt-Dyno say?

Is it louder or did it change the driving characteristics?

True, driving for me is literally a difference of night(cold) and day(hot).

where do you get that idea? why do you think the M2 box is so popular? why does pettit make a heat shield for the intakes? I mean i kinda see what your saying.. but if the air is already cooler your intake air temps are already lower before it gets to the IC therefor making the intake air temps lower when they get to the ports. At any point that you could have cooler air the better. They wouldn't sell boxes for the intakes or heat shields if they didn't help.

+1

He means to cover that rectangular hole in the top of the IC ducting. You are losing a lot of air out that hole as well as the one that goes to the battery. The two pictures show what I did with duct tape. Ugly, but effective.

I f I can, I'd say that an air intake a little bit more insulated from the heat of the engine would be better. I installed the ARC intake coupled to an GRedy SMIC and I think it's the best combination for stock turbines...

Zokus 07-27-08 03:10 AM

AntiSUV - Putting a piece of metal between the intake and the rad is not going to make a noticeable change in either power, or IAT. Between being compressed , and absorbing the residual heat from the exhaust side, it is going to stay a consistent temperature. It's not magic, it's thermodynamics.

Oliv - Again, 1 or 2 degree temp drop is not going to affect the density enough to matter.

FD3Smaniac - A proper heat shield, ducted with fresh air, does make a difference. That is why they're popular.


Anyways, I should have worded it better. Adding anything but a proper box/heatshield with ducted fresh air to those intakes is pointless and a waste of time.

I was never told to cover that up, and Mazda would not put it there if there was no purpose for it.

Again, I might be wrong. :)

Oliv 07-27-08 04:48 AM

I like this discussion even though this is one of the most discussed subject of rookies. But always nice to share opinions.

I have a PFS ducted SMIC with a HKS RS intake

The PFS duct has a hole on the side to connect to the PFS airbox (with a big KN cone inside).

Now I'm in between 2 choices:

- keep the HKS and run a 70mm hose to the mushroms (I really love the look of this intake). With this I'll bring fresh air to the intake but less to the IC
- instal the PFS airbox that I have, which is closed and shielded. But with this solution it aslo means less air to the IC as a part of it goes to the airbox.

I also have a vented headlight (Attain), but I really have doubts about the efficience here...

Dream Theater, sorry to invade your thread, but I guess this can be of interest also for you ;)
