As title really,which would you choose.

I have both the Roger Clarke kit and the APS inner wing cold air kit. The car is in for a map tweek at the end of January and thinking of changing from the APS which is currently on the car to the RCM. This is purely on the basis I don't like the fact the filter is low down enough to suck water from a big puddle and gets clogged with ****e easily. Also a ballache to remove the bumper every time the filter needs cleaned.

I know the idea is that the air it gets is colder but my local specialist did some testing on this and the maximum temp difference between the inner wing and behind the abs pump where I would position the Roger Clark was 6 degrees so not massively concerned about that. Also I run sti foglamp blanks so not that sure how much air gets in there for the APS to be of benefit.

If anyone has experience of both that would be ideal but all options on either are appreciated.

Cheers Ross.

 

I have had both on my car, and I now run an RCM cone and HKS filter above/behind the ABS pump.
If you're not using the OEM snorkel you will get a cold air feed through the gap where that used to sit so it's not as bad as it might seem, and a lot less risky than a puddle sucker

 

Your mapper may be able to suggest something dependant on your other mods

Mine will be running a custom kit and CAF

 

I've just fitted a RCM on my spec c

 

Martin j just scaled my RCM and mapped it no problem when you are on the move it will be have plenty of cold air put your hand out the window at 30 mph feel the air pressure might suffer alititle on a hot day in traffic but RCM or the new perran for good results I love the sound of mine . But if I was to buy new I would buy the perran as Martin j rates it big time

 

Well unless the mapper is insistent otherwise I'm going with the RCM as when I took the bumper off today the filter on the APS has perished badly around the mounting neck to the point of almost having holes in. I would consider buying a replacement filter but it was also rusty and really mucky as well which kind of confirms my thoughts.

Maf might have to be rescaled slightly as the current kit is larger bore than the rcm so will probably just end up swapping them round on the day.

 

i need a little help with this guys,my current blobeye is fitted with a perrin fmic and a inner wing induction kit (presume either perrin or aps)

it doesnt fit that great next to the intercooler pipework in the wing and as a result its pushing the plastic guard out which is now scrubbing on my drivers wheel when turning,also the filter looks really really dirty

on my previous blobeye i had a rcm and was happy with it and i would like another but will it fit as i have a fmic,any ideas if i can make it fit

heres my bay



heres my previous bay

 

I had an RCM induction kit on my old Spec C with a cold air feed routed from a fog cover duct. It might have been overkill on a 330bhp car but it did make a noticeable difference. Made a great noise too. ��

 

I'm quite happy with mine to be honest.

 

Here you go Shrek, it's not very clear perhaps but it's my RCM trumpet with a Perrin FMIC fitted to a MY05 car.
It is a bit tight but it will fit.

 

brilliant cheers mate,do you get a good cold air flow there? ie have you any running issues?

 

I've never had issues with high inlet temps with this setup, there is air flow through the inner wing apertures and as said above between the bonnet and grille where the snorkel use to be.
To get it to fit I bought a 76mm 45 degree elbow and ally connector, and cut about 40mm off the end of the trumpet connection. The blue wrap around the charge pipe near the header tank is there to stop the air filter wearing into the pipe.

 

happy days-cheers matey

are you running mafless?

 

No MAF

 

This was my plan except I will need to trim a little more off as my master cylinder stopper gets in the way a little. Thankfully I'm still running the sti top mount so at least there's no pipe work in the way!

Cheers for the feedback by the way,all much appreciated.

 

I'm still running a maf, is there still room for it

 

If you need to run a MAF maybe you could turn the housing to one side (I don't know if they have to be vertical?)

 

When I was running 450+bhp with a MAF, RCM trumpet and filter in the engine bay, and a cold air feed from the fog light cover, I had problems with reverse air flow over the MAF when coming to a halt, resulting in regular stalling.

Going MAF-less solved this, although that's not to say it couldn't have been sorted by some other (mapping) means.

 

Just found a picture:

 

I have heard of this before but not sure how common it is? Anyone else had this happen?

 

I really like the sound too, but was told by some people/mappers, it would make a difference at 330bhp, some even said it could harm performance.

What difference did you feel?

 

hey mate

do you get any induction sucking noise with having a front mount?

with my perrin fmic and inner wing kit i get no noise whereas my last impreza with top mount/rcm induction kit sounded great inside the car

 

Yes you can hear induction sounds, but it's not something I fuss over. I know some people like induction noise but for me it's just something that goes with the territory if you see what I mean. If it was silent it wouldn't be an issue.
If you're ever in the Wellingborough/Rushden area and want a look just send me a PM.

 

Ok matey cheers, are you on midland scoobies? If not get signed up

 

Ok I'll have a look
