Latest on DIY Induction Kit (pics)

[rt172]

Latest additions to my DIY induction kit. Extra 60mm duct from under the car to the airfilter compartment and an aluminium shield to keep the cold and warm air apart.

0-60 is now over 0.1 seconds quicker than with the standard airbox. Will be testing out the 0-100mph later on tonight with the AP22.

Thanks to Paul16v for the little heat shield.

If it works, then I salute you, well done!

 

[Cup-pa]

Looks like itll do the job very well, in good weather.

One issue. not picking or anything, but if you went through a flood / deep puddle, would the cold air pipes pick up enough water to get through the filter. susequently f**king the engine. Would it not be better to put the pipes higher up, say through the grill, bit of drilling etc - but safer??

It shouldnt be a problem, it isnt a sealed kit so it wont suck up like a Viper can, this is all about pushing cold air to the filter....

Good job Rhys, you gonna demo this at the next York dragway day??

 

[Paul16V]

Glad it works ok mate! Looked pretty professional actually when it was all in place hehe

 

[rt172]

Exactly Roamer, not sealed so unless I hit very deep water at 70mph i should be okay. It seems to get cool air in very well. The airfilter is quite cool after thrashing the car, although the aluminium gets quite warm. Done more AP22 runs tonight and the results are really favourable. Im not thinking its got way more bhp or anything, its times just suggest its making it run a bit quicker. I usually test at night (about 12c over the last month or two), and in 18-25c heat today its beaten its evening times.

Definitely taking it to York next weekend to see how it goes.

How cool does the inlet system get mate? (The bit with Renault in the top) with the viper on that was stoney cold after a good thrash gotta aim for that

 

[rt172]

Dunno, will check it out. Really made it COLD?!

If you can fill in the frame assembly that is to the left hand of the battery you will segregate the hot air from the engine. You will probably not need the heat shield over the K&N then. The lesser models have a solid panel instead of the frame assembly (as on my 1.6). I can give you a picture of this panel if you want. If you put rubber beading along the top of the frame it will seal against the inside of the bonnet. Thats what I did with mine which seems to work well (2 degC difference max from ambient at filter). I feed mine from a 75mm duct and PiperX Ramair kit on the lower grill.

FlyingScotsman - yes please. Can you send pics to mailto:rhys172@blueyonder.co..uk">rhys172@blueyonder.co..uk please? Where did you get that hose from? How much and what guage?

 

[Flying Scotsman]

Ill try and do the picture tomoz. The silver hose is a Green Filter 75mm hose from Halfords (~£11). The PiperX Ramair kit (~£30) was from Demon Tweaks. I fabricated a steel inline coupling to join the two tubes together behind the NS headlamp. I used one of the "bellends" from the PiperX kit and sprayed it matt black and sunk it into the lower grill. Notice the tube forms a lower U after the inlet. I put a small drain hole at the lowest point to allow water to drain out during downpours/washing ( I have fired a hose at the inlet whilst the engine is running and the filter never got wet .... beauty of a non sealed induction system).

Rhys, tried to email you but got bounced. Anyway heres a picture of the MK2 1600 battery plate.

If you can use this or do something similar using sheet alloy, you can profile it with the inside of the bonnet, maybe also put a profiled panel at 90 degs between the ECU and battery seggregating the corner from the rest of the engine. I used the soft rubber bead as found on the top of the slam panel (shown to the right of the picture) to seal the top of my air box to the bonnet (BTW, used a long welding rod to get the profile of the bonnet inside then laid it front to back over thr engine bay to guage height).

 

[rt172]

Oops, I put too manys dots in the address.

Definitely some food for thought there. Would be good to seal off the rest of the compartment. The cars been running quite nicely today despite the 31c temperature. It usually feels a touch sluggish in hot weather. Id like to try taking temperatures in various places in the engine bay to see whats hot and whats not. Is that a temp sensor in your airbox? Whats it like compared to ambient temp?

And thanks for showing us your "bellend"

 

[Flying Scotsman]

Rhys, well spotted. I had a temporary RS Components temperature guage with the sensor positioned as seen in the picture. I did tests a while back when the ambient was in the mid twenties. I put the sensor next to the wing mirror sensor and found the difference between the RS and the dash internal temp guage. When running I was seeing an average of 2 degC higher than ambient at the K&N (corrected). That was a mix of slow/30mph and higher speed motorway driving. When stopped and idling the difference went up another couple of degrees after a few minutes as expected. Things are definately much more responsive from when I had the K&N unshielded. Hoping to get a Unichip shortly to dial the mapping for this and my Magnex in correctly.

 

[Road_Shagger]

can i so anything like this on my 1.2 16v?

 

[rt172]

Of course, its the same principle, just a smaller engine. Just give it a try.
