Today had pipercross induction kit for cooper s fitted and dynoed here are the results.

141 89.4 2277.5
161 92.2 2058.6

run 2 induction kit 20 degree celcius

both runs were in 4th gear.
unfortunatly the bonnet was up on both runs as it was the only way to tie it down on the dyno.
It appears the car is definately starving for air as the increase up high is very clear ,I feel the improvement may be reduced with the bonnet down. This may explain why some people are claiming up to 12hp.
BTW these figures are at the wheels, 6kw=8.5kw at flyweel =12hp go figure? btw there was no airflow directly aimed at the bonnet but instead under the car to cool drive line/exhaust.

Now the winges,
1/ fitting on end of filter not tight on
hose seems 2-3mm small (does tighten
with hose clamp)
2/ filter needs support at end closest to
firewall tends to move around on the hose
trying to support all the weight.
3/ heatshield at front is rubbing on bonnet
insulation and will have to be modified.

Supposidly theese are to be used by jcw i wouldnt think they would accept thees faults even though the are minor and fixable.

Looking at the above chart im thinking of cutting a hole in the plastic divider behind the filter my only concern is whether i may create a vacum and suck all the air out .Any coments would be appreciated before i do the mod!!

SORRY THIS SO LONG.

Scott, did you take out the rubber piece between the planum and the "divider" so that more air could get in? Keith seems to be convinced that this will help.

Adam told me you got yours on Monday. Mine will arrive in my officeby morning. Really looking forward to fitting it. Can you actually feel the difference in throttle response?

BTW, there will be a drive to Marysville on Sunday. You coming? I am not sure who is going and if you were one of them, but there will be 6-7 MINI's apparently.

I wish I could come, its non stop rain here at the moment. Fitted my Pipercross kit. Definitely improved throttle response and more noise.

Let's see, flight from Heathrow to Melbourne takes less than 24hours...you can still make it!!! What are you waiting for???

[coops41]

Way, yes i can feel an improvement in throttle response in the mid range, driving home from mechanic seemed to get better the closer i got to home mech said computer would learn new air flow and the improvements may be greater than dynoed. I havent yet removed the plug that keith mentioned may do that to day back to back.

On a different note was looking and dreaming last night and I think with some minor modification ie cutting the intercooler plastic cover where the intercooler actually finishes you may be able to redirect some air from the bonnet scoop to the air filter.Will price cover first to see how much so i can return to std.

Sunday marysville? wasnt aware, would love to go but meant to be going to broadford for world champ round of super motard will be going back way via kangaroo ground kinglake etc should be fun!!

You know what the best way to find out is? Do some good, old-fashoned testing...on *your* car. I'll just wait for the results

Oh I like that idea very much. I will even help you guys out, on YOUR cars that is.

Just got mine delivered this afternoon. Can't wait to get home to fit it.

BTW, Adam wanted you to speak to you. He needs to fix something up with you, something to do with the invoice. He asked me to tell you to call him.

I installed my PiperX CAI the moment I got home last night (started the installation in suit and everything!!!). Very easy job, would only take 15 minutes. I took a lot longer, as I dropped a screw into the engine bay, and could not find it. I eventually did and that was the biggest drama in the whole install.

I also have the same complaints about the kit as Coops41 regarding the cone filter actually moving around as the hole is slightly too large. What I am doing in the interim is just to slot my business card in the hole to tighten it up a little. Have to think of a better way. Coops41, let me know if you do something about it.

Now for the drive impression. Oh before I forget, I took the plug out like suggested by Keith. I see what he has been talking about now. With that piece of rubber removed, airflow would be so much less retricted. In hind sight I should have driven with it on first and then take it off to see what the difference is. Coops41, let us know how you go with removing it. Anyway, I was immediately impressed with the crisper throttle response and torque in mid range. It was a cool night, so it helped the situation. But I have no doubt that it was a good purchase. After driving hard for half and hour, I open the bonnet to feel the air. The engine bay was very very warm, but when I put my hand in the airbox, it was cool. The metal on the filter were cold as well. It's quite amazing!

All in all, I think it's a good purchase. Go get one if you haven't got one yet.

Pipercross have noted the comments and will be looking in to them imidiatly,

Having fitted one myself I cannot remenber the filter being loose, but we will check and re-manufacture if needed.

My thoughts:-
Pipercross could very easily change the design, if they included a flat bracket on the metal cone end (the bit that fits through the heat shield hole) that butted up against the heatshield when attaching the air hose. One hole in the modded braket and another in the heat shield and voila, one little bolt and the filter is firmly attached to the heat shield.

I should maybe patent that, pipercross, you could pay me millions for my idea!!

Funny that had same idea and passed it on to our distrubuter in oz, for the moment have rapped some tape around the end of the cone to make it tighter.Also ground 3mm off sheild at front to stop hitting under bonnet, is yours hitting?

[eltel]

Gee guys, some pictures would be nice, so that the rest of us can understand what the hell you're talking about.

How does this affect your insurance?

I'll have a look at both installs on Sunday and mark them out of 10.

Eltel, i have a picture on my gallery or see here:-

I didn't have to make any mods, i didn't check to see if the heat shield fouled the undersode of the bonnet, my guess is it didn't but will have a look.
I have removed the kit as i am in the process of getting the Hartge engine upgrade:-

As for my insurance i never quite got round to telling my insurers, it was only in for a week and i have since sold it.

Does that clear everything up??

The previous pic maybe does not show, try this one. You can clearly see the front of the heat shield. The filter has a cylindrical outlet that goes through the shield and attaches to the black hose. A simple bracket onto the cylindrical part that would match up to the heat shield with a hole in it would then only require a bolt to make it a "tight" fit with no movement.
My filter cone just lay in behind the shield.

ok, im really curious, I'm assuming the induction kit you all installed was the open air cone filter design? no?

anyways, i was looking at this viper induction kit that was just brought over to the states by pipercross, it has the claimed 12 hp gain and it looks snazzy and all but it has a price tag of 320 us dollars...ouch.

would the money be worth it when i could get an open cone filter design for say 120? anyone have any idea? or anyone install the viper induction kit and have any comments?

[FLiPSiDE]

installed it in a snap, 10-15 minutes tops just need an 8mm socket and the little security bit set (but later noticed this coulda been taken off with a socket too)

its a hot day here in sydney so i drove all the way out 2 pick it up with aircon on, and its a slug off the line as we know, but with the new air filter it does seem a little more powerful off the line with aircon on, definitely revs out alot quicker, will test more and get pics later 2nite when it cools down

edit - driving to work this morning in the cool air, all i can say is MY GOD, i didnt expect such a noticable improvement, the car just picks up so well, and winds out so much quicker... i was a huge doubter, just put it on cause it looked cool and figured if it made a little difference i'd be happy enuff.. but damn

thanks to the guys at Fabre Australia, so friendly and helpful, i love it

i did mean to ask about pods for my twin SU's on the old mini.. i think i might get them too now
