Intercooler Upgrade or a Fan?

[alexturner]

Hey guys,

I'm looking to get more power from my 200tdi as it's lagging on the highway. Initially i considered swapping the tcase for a D1 box, but I'm starting to decide against that. Is it worth sending my intercooler to ASE and have it upgraded for $550?

Would fitting a decent electric fan to the intercooler make much of a difference? Also planning on the boost tweak.

Hey Alex,

Don’t waste your time looking for an intercooler in Aus.

Stay up late tonight and give Ali-Sport a ring in the UK. I got my brand new full-size intercooler delivered to the door for about $500.00

Agree 100%. Allisport have apparently achieved sub 9sec 0-100kmp/h in a Puma with their performance upgrades.

Not cheap in UK terms, but compared to Australian prices...

Drover,

You have done SO much to that lucky SVX of yours, haha. I might look into it, before I spend the cash, i'll pick up an electric fan from the wrecker and mount it behind the intercooler and do the injection pump tweak. It just needs a little more power :P

just had a look at the Allisport website,

Cop a look at this......

Now im thinking of going to the wreckers and picking up a big intercooler from a Supra or something and retro fitting it... more surface area and a cheaper option methinks.

Or this one.

I have toyed with the idea of buying a complete TD5 front, radiator, panel, condensor and intercooler and fitting it to my TDi.

:rocket:

I can get a supra intercooler for less than $100 :P

Jeff - Want to sell me your aircon? :P

dont go playing with things like supra intercoolers. Intercoolers are designed for the engine and turbo, they need to complement each other as a system.

Fitting a fan will do nothing for your intercooler, ie you are traveling at 100km on the road and that will be pushing more air past the intercooler than any fan that you could fit. A better designed intercooler with higher flow rate and surface area is the answer, that with a fuel and boost tweak will have you smiling :D.

At the moment then $800 for an Allisport full size is well out of my pocket. I'm thinking of doing something along these lines:

How To Increase The Performance Of Your 200/300tdi - LR4x4 - The Land Rover Forum (http://forums.lr4x4.com/index.php'showtopic=31)

What do you think?

[Bush65]

IMHO don't upgrade the stock intercooler - not enough bang for your $$$ unless you do serious injection pump and turbo upgrades. The existing intercooler is sufficient for reasonable increase in boost pressure from you stock turbo with a tweaked injector pump.

Adjusting the injection pump (not changing the intercooler will yield the power increase. Adjusting the actuator rod on the turbo will increase the boost pressure, which is needed to control black smoke and exhaust gas temperature.

Stock 200Tdi boost pressure is a little lower than for a stock 300Tdi, which probably accounts for the higher power/torque of the 300Tdi. Increasing boost up to something less than 18psi is OK.

Higher boost pressure than that is obtainable with the stock turbo, but then the compressor efficiency is getting poor to horrible, so creating lots of heat in the charge air and the need for much better intercooling, without proportional power gain.

Edit, one of the members here has produced a good guide for tweaking the pump - same principle but written much clearer than the thread that you linked to.

[Loubrey]

No further advice as I know far too little about 200Tdi's! I have however another link to Devon4x4 in the UK who will send you one by DHL airfreight at what looks like a lot less than your previous quote.

AlliSport are doing the up grade intercoolers for 200tdi's for 343GBH's or about $515AUD's.

Freight is $80 with a courier / 5 day delivery or cheaper with "snail mail".

$800 ????? Not sure where you got that from Alex.

[roverrescue]

It would a wise man who only listened to John (bush65 ).
When it comes to working with turbo dieso just listen to a pro like john. He wont sel you something you dont need.

How are the simple things like injectors, pump timing, induction restrictions?

I second what john has said.. that guy in the uk and his mods he would have been better with out that intercooler, triple the size is way to big for that turbo. just turn the fuel up a little and more booooooost:twisted:

[dromader driver]

i have wondered what temp drop could be obtained by a water spray over the intercooler set to come on automatically when the manifold inlet temp reached a certain level. latent heat of vapourisation and all that stuff. Some distilled water should fix the corrosion problem. :cool:

The kids are talking about iced water bath intercoolers for their 4 cylinder jap stuff.


Anyone tried it?

[cal415]

Drover, where are you getting the prices on the intercoolers? there ebay store lists a puma one for 470 pounds, im guessing that plus shipping works out alot more then 500??

[isuzurover]

x3 - do what John (Bush65) said.

That 343GBP is for the 200TDI,

470GBP for a PUMA is about what I paid. It will cost about $800 to your door. That is $400 - $500 cheaper than anywhere in Aus.

[alexturner]

Thanks for the advice guys - I'll start tuning the pump when I return home. Does anyone have a link to the pump tweaking guide?

Thanks mate,

Before you do anything or change anything check how tight your throttle cable is, for some reason Tdi's seem to loosen themselves and nearly every Tdi i have seen(even some which have just had "performance work" done) has had a loose cable. Tighten it till you take up the slack to the arm and you will notice a big difference in power and responsiveness, also give your stock intercooler a good clean, you may be happy with how your stock engine goes without having modify if you are only after a little bit more. I ask everyone who leaves the shop to honk there horn if they notice a good difference as soon as they take off and so far have 100% sucess rate with throttle cables, simple but overlooked.
