Side intake Pipes (SIP's) Talk to me!
Should I bother? I have a FMIC and stage 3 turbo in my garage ready to go on. You can pick up a SIP and filter for £50-60. I'm aiming for no more than 300BHP as my clutch is standard and new. Should I fit a SIP? I'm also wary of it sucking in water, with it being lower than standard. Flea if you're seeing this, I value your opinion greatly.

You can use a 90 degree bend if you are worried about water. I have used a SIP for several years and had no problems with water.
I like the sound from the dump valve and with a SIP and cone filter the sound is even better.

Straight induction pipe = do it, even if its just for the noise

Noise is much more amazing/loud and for my coupe the throttle respond improved

how many rivers do you drive through?the water would have to be pretty deep.water vapour/spray wont be a problem

APEXi make it even better.....:)

Do it, just dont drive fast through big puddles.

That.

I just posted a couple of weeks ago when I drove through a big puddle and sucked up a load of water through the air filter.

Nearly crapped my pants, but the water luckily never made it into the engine. It did take me a few hours to strip everything down(including FMIC) to drain all the water.

Does anyone know where to get the apexi filter from and the size??

Ebay. You will need the adaptor plate with it. I think they are around £90 now

Generally I don't advise using a SIP these days as the gains are not significant. I have tuned cars before and after, and there is no difference. That said, if you do use one (and there are other reasons to), then make sure the MAF is positioned as far from the turbo as possible preferably after a 45/90 degree bend.

I think you mean you don't advise a SIP, Flea?

Can you give us an example?
Have you tested the SIP on a 400 HP car and seen no benefits?

He advised me against a sip, so I've not bothered. They look good though

And sound awesome.

And cause idling problems. Don't bother is my advice.

I have used it for a year now, and not a problem at all.
Turbo...reducer hose....SIP...Coupler hose....MAF...90* bend hose...Apexi air filter cone

That is my configuration

I've had mine fitted for several years, it's one of barbz's originals with RamAir filter, no bends anywhere so fitler right down on the floor, and not even a hint of any idling problem, but on mine the air flows in the opposite direction to yours Kenge

RamAir filter - short hose - MAF (upside down) - short hose - SIP - reducer hose - GT28R turbo

Just go for it (a lot cheaper nowadays!)

What about the spool up. Is it quicker?

I think a slowly tapered SIP like the ProAlloy is preferred. It seems a short reducer hose destroys spool-up, so it did on mine (3" down to GT28R) anyway, by 500rpm or so.

i have not long bought a sip but i have not had the time to fit it has anybody got some pis of the best way mounting the pipe

Hi. When I had my SIP installed I RR before and after and although I had slightly faster spool up (very slightly) my inlet temps went up. Just another factor to think about.

Cheers

I'm not going to bother with a SIP. Thanks for all your input guys.

Hi ive got one of these sips fitted when i bought the car.
Thing is that i orded a green cotton cone filter and it is
Massive it cam with a alloy pipe so i had to extend the sip.
With abit of samco off the maf then the alloy pipe so now the cotton is sitting upwards if this makes sence to any of You have i taken any power away from the coupe its 250bhp at the moment cheers chris.
If need be ill get a photo up.
