Technical making my self an induction kit - a pete special

[gaz.d]

i have finally got round to making myself an induction kit for the sei

i have got a few questions

1. Does it matter how long the hosing is to get to the 'bob' (thing on top of engine), just aslong as its got minimal bends in, or is shorter better?

2. I want the cone to go in the passanger side hole in the bumper (check pic), are there any problems with it being there, i am scared of sucking in water, as im guessing this is bad

cheers

Gaz, you know me, know nothing about cars but my pennies worth:

1. Does it matter how long the hosing is to get to the 'bob' (thing on top of engine), just aslong as its got minimal bends in, or is shorter better

Friction is caused by the pipe wall, the longer the pipe the more it has an affect, the shorter it is, the higher the airflow for the same force. - That's in engineering terms, whether it makes any difference whatsoever in this case I don't know!

2. I want the cone to go in the passanger side hole in the bumper (check pic), are there any problems with it being there, i am scared of sucking in water, as im guessing this is bad

The mk2 espace had it's intake (AFAIK) just there, it meant that fording anything more than a puddle put the engine at risk! We nearly bought a 2.0 petrol version which had had a brand new engine put in following water going into the engine like that.

My dad had a mk2 espace wen they first came out, couple years down the line we were out shopping and there was heavy rain and the roads were flooded, thinking that cause the car is high enuf we could drive through the massive river like puddle, were all the smaller cars had broke down.

Everything was going fine till bout half way through the puddle and a car went through the other side so fast it made a massive wave that covered the bonnet, bye bye engine, the engine just stoped and wouldnt start, cost thousends to fix and was never the same to had to sell it.

Gaz wat i would do is make the end of the hose point downwards a little so if anything did actually get in there it can fall/pour out instead of only going one way, up to ya filter.

cheers i have part finished it now, am waiting on the induction cone, so i know for sure where to posistion it

paul - im guessing you mean yes on my first question , if that the case oh crap, a re-think is required

damn you water , its hopefully gonna be just sitting right at the top of the meshed bit, but still enough for water ....hmmmm

 

[gaz.d]

ah before i forget, i have another question, nothing to do with induction though

its most probably a really stupid question but its got me so confused, that its bugging the hell out of me

had car up on jack, took car out of gear, started engine and the wheel that was up in the air was spinning .......errm how and why didnt my car fly of jack and into house if its spinning, surely same would happen to wheel that was on ground, i didnt notice if the speed of the wheel increased with an increase in revs

i really need to know as its gonna bug me forever :bang:

:yeahthat:

it used to happen on my ped, and no one could explain to me why.... They just said something about 'tick over' and that its not enough power to move the it. Notice that you could stop it spinning with your hand?

 

[gaz.d]

i didnt really fancy sticking my hand into a moving wheel , i didnt wanna do any damage to the car

lol, the car wheel might be turning with a little more power than my ped did now i am thinking about it.

I have got my cold air feed in that part of the bumper btw, but it has a hole in the first bend now because of stuff flicking up into it. (probably stones). My pipe is only made out of thin metal though.

 

[The Negotiator]

Yes Gaz, shorter the better and the fewer sudden bends the better. Also the fewer large to small/small to large connections the better. (NB: all theoretically)

Gaz, I tihnk (remember me and car knowledge) you're "problem" is to do with the differential? I am probably wrong completely though.

 

[gaz.d]

theres 3 connections to get it to the bottom corner, go from 45mm - 38mm, i got the wrong hose connectors

maybe i should of just brought the gsr kit

 

[The Negotiator]

Is it a gradual change or a sudden change? TBH, either way I wouldn't worry hugely lol

You SHOULDN'T have bought anything else, it's much more fun this way.

 

[gaz.d]

its a sudden change on each one, i not really made it for performance, i want a big noise

 

[surfin_fella]

The wheel spinning thing happens on mine too. nothing to worry about, just keep your head outta the way!lol

About your induction hosing, i'd have it a little higher than the bottom of the bumper and don't have it directly on your filter. leave a bit of a gap and point it away from the cone. The vaccum on the engine willsuck in the passing air but if any water was to go up the feed is given space to come out the other side. I don't think that makes any sense. Just imagine me sat here making images with my hands!lol

it makes some sense, im still trying to picture it

im not to sure about pointing it away from the cone, as the cone will be sitting down there attached to the hosing that goes direct to engine

I've got the bob or plenum chamber to do the same thing Gaz and my first port of cal was going to be asking mckrich or mase the spec of the hosing they bought from SFS so I could get the right one and also what kind of filter did they use?

Hopefull they'll see this and post something.

[gaz.d]

i used sfs hosing, i would of really wanted the thickness of the pipe to be bigger, but it seems sturdy enough sitting in the engine bay

i wish i looked around for hosing though as i got intruded by tweeks for it :bang:

Liam,
it was a 76-51mm reducing 90 Deg Elbow with 150mm legs (the maximum length they do) it cost me 23.50 all in but I think they missed off the VAT by mistake so you may jhave to pay a bit more. SFS are on 01582 488040.

Hope this helps.

Michael

mckrich, is there any chance you could post a pic up, i am slightly confused about yours

i also have ecu sorted now one of your chips, is there any chance you could send me some info over PM, as i cleaned out all my old messages

thanks

This isn't in any way useful but the spinning wheel in neutral thing is down to friction between various gears/shafts in the gearbox, if you grab the wheel it should stop (I'm not responsible if you try it and lose a few fingers though!) although the other side will carry on cos of the diff.

 

[polecat]

Gaz all you have to do with the cold air feed is to keep the end a few inches away from the filter so that if any crap is sucked in it doesn't end up flooding the filter and getting into the engine.

The end in the car does not have to point directly at the filter to work well.
