Z, now we are talking. Thats what I am going to do with my current set up with the big plenum. Thanks for pic.

that beninca airbox looks sweet!!
how much does it cost?
hi kev, how are you doing?

I think it costs AUS$350 with hose and clamp, but may not include the 4" aluminum adapter. You need to confirm with him. If you're buying from europe, I think it's worth it. It will be less than $250 euro.

I thought about modifying my own airbox, but a lot of the shops here charge US$100/hr. So if it takes 2 hours to modify the stock airbox, then that's $200. Then you have to budget for "mistakes" done by the shop who looks at our cars and say "hey is that an Alpher Romero or somethin'? What is that, an eye-talien car? ".

**** that!

Why not buy from someone who has sold so many of these boxes which are known to fit? Makes more sense.

thank you Z!!
i emailed him!

Hi RZ, hows the car coming on ? Z, I am going with this similiar intake of race car on the 3.2. This intake must work as my 3.0l is one of the strongest 3.0l 24v on this dyno and all its got is the gta 2 spec intake with the gotech. Ok so the power only peaks up above 6000rpm(which is normal). I got some interesting data from the dyno room as mentioned on my cars where power occurs with the particular specs. Must say my 3.7 is not nearly as strong as yours but then im an amateur. Its got huge midrange.
If you dont have individual throttles there is huge power to be found in the plennum and intake as I found . Hence watching the other thread closely. I am gonna bigger than this one.

Kev & RZ,

The lower airbox should be opened up too, I will post some pics of what I did. I like the stock paper element for longevity of the engine (better filtration performance). I think the flow may offset the slightly more restrictive nature of paper filters.

My 3.0 24V will have about 11:1 compression, and custom cams. I was told that the cams total duration in of itself is not the only thing to pay attention too. The ramp rate is also important. Some cams have such an early opening (mostly on large duration cams) on the intake side that they bleed off some compression. I will get some nice cams with good lobe centers, fast ramp without being too nasty on the tappets as well as good duration.

I'm testing out a set of these type of cams next week on my 12V. IF (VERY BIG IF) I can get 200 whp from the 12V, I can only imagine what the 24V can put out with 11:1 compression, 10mm custom cams, adjustable pulleys for dyno turning, short 42 mm ID runners and 1.625" ID headers!!! I think for the 24V the limitation for the cams and revs are the hydraulic lifters.

nice steup kevin!!

and Z 200 whp from a 12v??you must perform miracles!!

my engine is already since june 2008 in the car, but we needed some parts from south afrika to come...

they didn't show up yet!
we sourced the parts from performatek and now i am waiting for my mechanic to continue his work.
i hope this month???

200whp from a 2.5 is for pussies just check out this thread on that 'other' BB for all the info you need for your super tuning enlightenment*

* - in case it is not immediately apparent, that statement is dripping with sarcasm.

200 whp from a 3.0 12V is realistic.

Look at Mike's 12V, >175 bhp with 9.5:1 pistons, s-cams and Jetronic.

OK, enough talk about this, let's get back to Kev's car. This is his thread.

When I get the cams, I will dyno my car and start a new thread.

Kev,

Here are some photos of my lower and upper airbox:

For the lower airbox I made a HUGE cutout. At a later stage I will form some sheet metal to make it look nicer. I'm getting air from the sheet metal which I cut off from, right beside the radiator mount.

hi Z,
my airbox was cut the same way.
i ordered the lid from beninca.
i hope this mod will bring me a 100 HP

Hi Marc

Does Beninca have his pricing anywhere for the air box / lid?

Or did you just phone him?

John

Best is to just call him I think.

350 aus $ plus shipping 120 aus$ =$$$$$

Whoah, If i convert that to our banana currency I could buy another GTV here.
Z whats the intake size. have you a few more pics ? Check out these runners 48mm. They are going to be moulded in plastic. Dont ask price as they are not available and who knows which set up they will benefit until testing starts.
