4.5 induction hose on engine

[pmessling]

What options do i have about replacing the induction hoses that cross the top of the engine. The ones on the car which i'm picking up on Monday are very faded purple and would like to replace it to either its former glory or a nice blue to match the paint, have seen the nice looking carbon ones and carbon air boxes which i may consider in the future?

(looking forward to monday)

They don't stay new looking for long, even new ones will soon look faded and worn. Provided they are still working and haven't collapsed I would just live with them and save your money for something else - you will be spending money on it
Options for replacement hoses are a short induction kit, with which you will need an engine remap, that will be £1000+. Or replace with standard ones which are still about £450 http://www.clever-trevor.net/tvr-part-category/3-e...

I bought a 2nd hand set that were virtually new (less than 1K on them). I have had them on for a few months. I clean them when I have the hood up and so far they have remained as purple as something purple.

You can fit the Whirlwind Short induction kit without a remap although ideally a remap would optimise performance and driveability, these can also be bought with a fueling chip to compensate if Jools is still selling these through Raceproved?

I'd go with Jooll's kit everytime if only for the smoothing of delivery and the 'çool' chip option but don't ACT do a short induction ket as well ?

Yes they do.

By Joolz kit do you mean Joolz whirlwind, remap and cooling option? I assume so.

I dont think he does generic chips anymore (issues with cars being poorly before adding a generic chip and then customers not getting what they hoped for - due to poor tpots, cats, throttle bodies etc etc)

I wouldnt want short induction without a remap - messing about with air flow without fuelling compensations (I think) doesnt seem a good idea IMHO

The difference on an average std car is marginal by installing a short induction kit. But as you've mentioned not all Cerbs are running the same so there may well be variance (std maps also vary! as well as potential technical issues) on some which will lead to less than happy running. For me this is down to an owner taking responsibility for this eventuality occurring as idealy a remap to suit the hoses is advised. It doesn't therefore surprise me that Joolz may not offer the chip anymore. But I suppose if you did visit Raceproved to have the hoses fitted then Joolz could offer a std fueling chip that wouldn't massively increase performance but suits the short induction, or he could offer bespoke for performance gains and improved driveability?

Is it possible to do a DIY short induction kit?

i.e purchase pre-formed hoses off, say, ebay?

Must admit, not really looked that the air box arrangement other than removing the OS one to sort the breather leak

In theory yes you could, but in practice they would be a nightmare to make fit as you will only be able to purchase straight hoses plus it will be difficult for you to get the correct bend angle, the hoses are also off set.

No it isn't. Thst's why they are so expensive. They have to be specially formed on a mould. They are tapered, offset and have a bend in them. There really is no point in fitting a short induction kit without a re-map.

But I do have one of Julians chips in my possession

May not be perfect for my car, but perhaps one day I might fit along with propper induction

A remap is adviseable, but if you have a chip then dependant upon which one it is then it may be ok. Worse case, if you fit the hoses and it runs worse than before then you just swap the hoses or chip back.

When I was developing the Whirlwind Hoses I fitted a prototype set to my car that were made from generic hoses. I didn't adjust the map to start with and the car felt fine. When it was checked for fuelling etc then yes it needed adjusting to opitimise air flow and fueling, this also increase power/torque etc, but it wasn't at a point where it was running too lean/rich. Obviously this will differ from car to car, it's all about being sensible.

Ooohh, I like them!

was thinking about polished stainless 90 degree short tubes with silicon hose joiners, would that work?

Again, in theory yes but you would either have to shape the two silcone hose joiners or you would have to shape the stainless steel tubes to accomodate the angle and then off set.......not worth it. The other negative is that stainless steel would stay very hot which is not good for airflow.

If you do a search on here there are some carbon fibre std replacements, but these are very expensive.

Stcik with silicone and go for Whirlwind Induction kit or the ACT kit.

Or save your money and spend on the more important things eg suspension, brakes and driver training. Once you go short induction then your starting to chase horses. There are additional benefits like driveability and binning old hoses but ultimately you're gonna get more power before you have got to grips with your standard 380 ish.
