Induction Kit

[Ravi]

Hello People, Im just round the corner from d-tweeks, my credit card is burning ahole in my skyrocket, is it worth but and indiction kit for my e30 sport? if so are the 17.99 ones on ebay any good or should i just get one from tweeks?? k&p Piperx????

cheers bmw guru's

well, most people on hear don't rate them that highly. on highly tuned engines then they are more useful but on a stock engine then they aren't all that brilliant. plus you'll have to make a heat shield and make an air intake feed from the front of the car to deliver cold air to it instead of hot air from the engine bay. hot air means that the air is less dense and therefor there is less getting into the cylinder making the car LESS powerful. the colder the air the better basically. i would stick with the standard airbox to tell you the truth and if you wish, change the paper element for a K&N one or something like that rather than the standard one.


hope this helps.

Hear hear!

Most induction kits seem to be a load of pap, also, the standard air filter's in no way a restriction on most (if not all) cars.

If you really want one go for the BMC item in the gourp buys section.

No one seem to lose any power form thsoe and there are reports of better throttle repsonse and better top end feeling.

cheers for the response people but its too late, i bought a k&n last night before any of you replied, you are all bloody right, made a little difference to fourth & fifth but not much else is noticable. it cost 89 rips and i tell you what the instructions were shit!!!! i ended up having to cut down the bolts on the afm to accomodate the filter, the instructions tell you to remove these bolts, but how is this possible when the have been bonded to the afm??? k&n are absolutly shite!!!!!

A bit late now, sorry. When I got my standalone computer fitted and the AFM removed (it uses MAP now) I was also going to get an induction kit (or get the mechanic to make something up). So when he had it on the dyno tuning it he took off the air box completely for a dyno run and it made less power. I know that is without a heat shield but it was also only for 1 dyno run so the heat build up wouldn't have been too bad (although it was a hot day so?). Anyway it was enough for the mechanic to say that I didn't need an induction kit and I should keep with the airbox.

aston what are you trying to do to me? ive just blasted 89 spondoulies on this piece of shit!!!!! that it, where r the reazors, im putting coldplay on and topping my self!!!

i cant even take the filter back as it has been fitted

absolutly gutted, people be aware, filters for bm's are shite!!!! (unless its something other than a k&n. he he)

Don't despair about this Ravi, there are a couple of options to consider:

(1) assuming you have induction kit fitted properly, you could make up a heat shield for around the cone. It will take a bit of work, but I'm sure you will get some tips from other e30zoners on how to do this.

(2) contact the company you bought it from, tell them the kit is sh*t and demand your money back from them. Assuming they agree, send back the kit and get a refund which you can buy a K&N panel filter from. However, if you have cut some bolts it might take a bit of work to undo the conversion.

We have all bought stuff with high hopes that werent realised, thats why the e30zone is a great place for sharing experiences (good or bad).

[astondg]

Yeah sorry, that information was really for other people who might read this in the future. ALSO my car is a 323i so maybe it is different with yours. To start with I have a smaller throttle body that is probably restricting air flow. You said you can notice a difference in higher gears so that is good. With a heat shield it might be even better.

I just spent AUD$2300 on that computer (fitted and tuned) and have noticed very little to no difference and my lap times haven't changed so I know how it feels when something like that happens.

thats a lot of cash, next thing im doing is a full custom exhaust and super chip, then its straight on the magix road that goes nowhere to see how much she is kicking out, its been stood for 4 years so at the mo its about 140bhp??? when its tuned im hoping for about 175 (if im lucky.lol)

[M5pilot]

Custom exhausts are an unknown quantity. Just get something like a Scorpion which sounds good and is built very well.

Ive known Custom Exhausts to lose you power.

As for Superchip......NO!

E30zone chip is based on something much more tasty and is shit loads cheaper too.

You've already been hit with the K&N which is a waste of time. Why dont you just go the full hog and do things properly.

Take your car and get a MAF conversion done. That include a full custom remap, a unichip and it will make the engine as it is perform to its best potential. In the process get a 6 branch fitted and a big bore throttle body.

The MAF conversion can be done for around Ԛ£700-Ԛ£800 and you WILL feel the difference!

Jst an additional note, exhausts dont do much for power at all. Stick with your system if its a good one and spend the money on something else.

[Ravi]

This may be a daft question, but do you drive a m5? if so which model? the bloke who had the car befor me fitted an ansa exhaust, it is mild steel and is the shitest thing ive ever seen, sounds crap, raspy and the tailpipes stick out at a 45degree angle. shite!!!! as for the chip, please give us some details about the maf conversion, what figures have you seen from this, cheers for the advice

Bloody hell!

Does the MAF thing really cost Ԛ£800!?

For that money, you could buy a fully mapable engine management system and lose the air flow sensor altogether!

Especially if you don't plan you go forced induction, you could get the new baby Emerald ECU which is about Ԛ£400+VAT I think

EDIT> Oh yeah, as a general rule there's not much power to be had from changing and exhaust system. It's the manifold which can alter the characteristics of the engine.

Well I have the 6 branch and exhuast and I just got that new computer which included removal of the AFM so it now uses MAP (at least as good as MAF) and I have noticed no difference to performance (I did notice a slight change to the powerband) and so far my lap times back me up on that. So even something like that doesn't seem worth it to me.
