Enclosed induction - any point?

17th April 2004, 23:58

This is probably a stupid question, but here goes anyway...

I've heard good things about the Green forced air induction kit, and am thinking about buying one. However, I don't have enough money at the moment to upgrade the exhaust system on my (standard) VTS. I know with the kit it'll probably sound a bit louder (not TOO loud I hope - I'm trying to keep the car reasonably subtle), but I'm more interested in getting a little more power.

So my question is: will I notice any difference at all with the enclosed induction kit without other performance mods? I know it's likely to be very small, but can I expect to feel a change in the car?

you will have an increase of approx 5bhp. You wont feel any difference in the car. It will just sound different. Dont waste any money on an induction kit that isnt enclosed as you wont get as good performance.

its still worth while really as you seem to have the scope for upgrading the exhaust eventually.

you may feel the car pulling better or smoother

if its a mk2 vts you have then the green enclosed kit is a really shit fit. i had to cut bits off of mine to get it flush with the slam panel and also extend the bolt holes because they never lined up properly!! then after bout 10 days of the kit being on the car one side had snapped. really shit for a £160 filter.

nice note tho and it does seem more responsive

on my mk2 vts, my first mod was the green enclosed. was not a problem to fit at all. just had to grind a bit off the pas bracket. nice(muffled) noise and slight power increase. revved alot easier

Still haven't bought one! Too skint! Will get round to it eventually though.

I have a '97 VTS. I've heard that the Greens have bad build quality but that the newer ones are better?

I just bought one for my Mk 2 VTR and the fit was spot on. No cutting of the scoop was required at all. I did cut the plastic pipe from the filter down a bit as I think the kit is universal on the new ones. I'm a little concerned about the quality of the plastic in the long run though, it seems very brittle. Performance-wise though I've definitely gained a few ponies from full exhaust and the Green.

in answer to the question in the title here....Yes!

It's all about the temp of the air going into the inlet.

For example: On my vtr powered ax i have a haltech ecu, this allows me to use the software from a laptop and veiw the engine peramiters in real time.

Now, i have a non-enclosed pipercross filter that sucks it's air from inside the engine bay.

Tonight, the ambiant(outside) air temp was aprox 23'C, yet on my way home the temrature at the throttle housing was at times, sitting in trafic, rising as high as 58'C.
Once in clean air, the temp would drop as low as 41'C.

The difference in engine performance between 58'C and 41'C is amasingly different, I'm talking maby 10bhp or more!

So there you have it, science in action, sad as, i know, but living proof that cold dense air WILL give you more bhp than warm thin air.
