3.2 mods

[Guest]

Hi,
Has any one had the following modifications done to their 3.2?

1. Induction kit
2. Straight through exhaust, without silencers.

If so what were the benefits?

Thanks

2. Straight through exhaust, without silencers.

I assume that this will be for racing only ?
They tell me that the normal exhaust (which I had replaced, of course) is quite good for the road - back pressure et all.

I have a sort of induction kit on mine (K&N etc.), but this was because the normal one would not still fit.

Not helping much, am I ?

I read this months 911 and Porsche world, which contained some cars with these mods.
It is not for racing.
Have you just put a K&N filter in?, I heard it only creates a nice sound.

Hi there, here is the K&N filter, great sound no gain though!

 

[Guest]

The reason that mine has a K&N is because it is connected directly to the input of the supercharger - there is no room for anything else !
The installation is just like the one in the current 911 and Porsche world (fitted by the same person), apart from the air-con (which meant a different drive belt).

Hi,
I' m a bit confused with the K&N.
Some K&N' s are just replacements for the square air filter in the box.
However the one in the picture above appears to be the filter and box in one.

Can you advise which is best, and the prices for both pls?

This cone-shaped K&N filter replaces both the box, and the filter. The box is only there to support/protect the filter - K&N filters are self supporting, so no box.

In terms of which one is better, lets hope someone with a normal 3.2 can answer that.

Hi,
In the picture above, what is that little filter thing on the right?
Also how much does this K&N cone cost?

thanks

In the picture above, what is that little filter thing on the right?

I hadn' t noticed that before - I assume it is a breather filter. The oil tank vent (to vent excess oil fumes) would be into the intake somewhere, upstream of the throttle body; the oil tank is on the right, below the filter.

Mind you, I could be entirely wrong (as if !)

Mine hasn' t got one.

 

[Guest]

John you' re right it is the breather. It is attached to the stud left behind when the box was removed! thought it looked better there[]

Gosh, right for once !

Now, I think I ought to go and see how they have solved the same problem with mine - you' d think I would have noticed after all this time.

 

[Guest]

I have spoken to K&N and they have advised that they do not do an induction kit for the 3.2.
Where did the above come from?, it must have been specifically made.
They only supply a filter element, which replaces the standard filter and leaves the box intact.

Hmmm......

Couldn' t resist looking at the home page of this Sikh site, having recently visited the new temple in Southall (great place, very friendly, we even got a guided tour).

I am an atheist, and ' er indoors is Buddhist, but we like visting different religion' s ' temples' .

I know this is off-subject, but I am in inquisitive soul (OK, nosy !). So, back to porkers.

 

[Guest]

the filter and breather came from simon at essential styling. The breather has K&N on it but I guess the cone could be anyones[&:] sounds great though[] just like a good women- all s*** and no b***[][8D]

 

[Guest]

John,
Nice to know you liked the temple, it' s one of my locals, and at approx 18 milllion to build even Prince Charles came for a peak!

As for the filter, I might get an element, once my car has been repaired from the accident!

Cheers

At risk of contradicting John (oh what the hell, I' ll do it anyway) I think the airbox is there to do more that protect the filter..

I' m being slightly picky, but any structure between the air inlet and the combustion chamber is " seen" by the engine as part of the induction system, and this includes that biscuit tin we call the " airbox"

Theory has it that some engines like to breath from still air - relying on the space of an airbox (pre- or post air filter) as part of a resonant chamber to change the frequency of the port pulsations to help with induction.

This is most certainly the case with road cars where in order to drive, you need a wide engine range and smooth torque delivery. (Varioram is a good example, but so is variable inlet on any Vauxhall 2.5 V6)

A small inlet dimension, and no plennum / airbox promotes good breathing at high speed only at wide open throttle and high engine revs.

So...in summary Airbox' s might have a function after all, and sometimes it' s not all bad. I learnt all of this as part of working and was involved with 4 very very well known car manufacturers performing hundreds of hours of dyno testing to optimise the size / shape / nature of the inlet. I was there to do other stuff on the sites (sell would you believe it) but I just couldn' t resist the acccess to engineering at this level.

But...when you' re racing, have forced induction (super / turbo-supercharge) then all bets are off - the rules are very different.

At risk of contradicting John

What the hell, do it anyway !
You are quite correct about the inlet side, and I can only speak from the forced induction side.

I will go away now.

Hi folks, Good discussion.

The picture of the car fitted with the twin cones is one of my kits. I havent power tested one of these and there is a chain of thought that says bottom end torque benefits from an airbox but the induction kits sound great and seem to increase performance at the top end. I made the kit for my car initially as it looks nice and sounds nice and I felt as though i could accelerate faster at the top end and after all low end torque is not something i care much about although I cant feel any difference at low revs anyway, i guess if you want to pull a caravan its worth thinking about torque.

the picture shows one of our stainless steel cones, I can supply the same kit with a K&N oiled cotton cone filter if you prefer. The stainless is rated for engines to 500BHP and is the most common version used on Supra twin turbos and escort cosworths, whereas the equivalent K&N is rated up to 340BHP. so both are fine for our cars.

You can see these and come for a chat on my stand at Eynsham hall if you want to check it out for yourself.

hi neill, just looking at some old posts and come across pic of your engine, have you ever cleaned it or was it this clean when you got the car. if you do clean it yourself any chance you can post back and tell me what you use on the alloy.
cheers steve
