If you want your TDI to be quick...

[Ian]

Well, I know it's not Fiat related, but I know a few of us have VAG TDI's and there are some thinking about converting

I'll take the 1.9 TDI for example (made from 01 to 05) which comes in 2 main variants - the 130BHP and the 150BHP

I, personally have the 130BHP; for insurance purposes.

Standard items will push upto approximately the following;

Turbocharger = 210BHP
Injectors = 190BHP
Clutch = 210BHP

A standard remap can give you upto around 180BHP without any other modifications - but this is when, if you require serious power, serious money needs to be spent.

A new turbo will cost around £1000, good for 350BHP
New PD racing injectors are £950 which are good for 350BHP and up.
An uprated SACHS clutch, fitted will cost £781. Good for 400BHP

And of course, don't forget the live remap, £600?
I've explored all "feasable" possibilites of a REALLY quick TDI, and, really, there's pretty much only one. NOS.

The TDI's are inherently stronger than their petrol counterparts (as we all know anyway), and diesel-NOS systems are just about becoming readily available, as such. You can cram a 100BHP shot of NOS onto a diesel, with an 11lb tank running 900PSI in the bottle (with a bottle warmer), and an uprated clutch, and see 300BHP without a progressive controller.

The theory is that, diesels run very rich, and therefore have excessive fuel to burn (hence why you see lots of black smoke when you boot it )

So, for around £2,000 you can have a 300BHP diesel - assuming you have a decat pipe too.

Just food for thought.

You can also assume that after battering the f*ck out of the crank, bearings, rods and pistons let alone the poor gearbox and driveshafts that it will be fooked in 1/4 of the usual time, if not less! There is no such thing as 'free' power. It will just wear out faster.

Nice idea tho'.

Anonymous.

There is someone running 350BHP without NOS in a 1.9TDI with standard internals, and has done for well into the 20k+ region of miles.

Please state your name and your location.

Thank you - Come Again.

 

[Ian]

WITH NOS, sorry. Dyno'd at 249.1 + 100BHP shot of NOS.

 

[Darren]

yeah but remember on a N/A car 100Bhp of nos does not actually give you 100bhp dont know about diesles though ?? hmm

 

[Joske]

I remember celtic tuning saying something similar. That you'll need an uprated turbo, a full exhaust, decat, air filter and a remap and you'll be running 250BHP+. Thats for either 130BHP or 150BHP VW.

Ian, if you want NOS visit http://www.earls.co.uk or give our sales team a call on 01803 869850. I'm sure we can sort you something out a bit cheaper.
Plus our parters Docking Engineering will be able to sort you out with an uprated intercooler if you so desire!

 

[g5een]

was looking into these diesels. 2k i found new turbo, ecu etc. 230bhp + crazy torque. dunno bout 300+tho

 

[Ian]

Indeed - I will need a new Intercooler - For sure.

Reason I say that beacuse the 130BHP version is in the wheel-arch and the 150BHP version is front mounted. I keep blowing my Turbo Pipe too at the EGR valve - I can't find a suitable replacement for the OEM one.

Does that company manufacture custom stainless steel pipes too? Or something along that derivative.. cheers.

 

[beeson100]

What size is the pipe Ian? We do braided stainless steel hoses that go up to pretty large but it's probably not what you're looking for. Most of the stuff they work with at Docking is ally. Have you got a picture of what you need?

Who won Le Man last year again??

 

[RR]

Le Mans, you mean?

No idea - do tell. Was it a diesel powered car?

 

[beeson100]

That's the ticket..with an s. Yeah it was I believe. Remember the diesel land speed record set by JCB too? We supplied the radiators and hoses for that Diesel power does seem to be on it's way...I prefer the sound an smell of a decent petrol engine though!

Beeson,

Here is a pic of a 150PD Anniversary with what I want.

I've circled the problem area (mine is currently a silicon hose that runs down to the nearest wheelarch on that picture. This particular picture has n FMIC.

I really do need a set-up like the above, but I'm not sure where to go, or what Intercooler to go for? Or what pipes to even go for?

Thanks !

They could knock that up for you no problem. You're from Liverpool though aren't you..Silverstone is a bit far for you to travel down I guess! I'll have a word with one of the guys tomorrow and see what he says.

Hi Ian,

Diesel NOS systems are certainly becoming more popular. And being a turbo'd system already you will see larger gains than the predicted gains for the jet size.

You could see 100bhp-150bhp extra power when using 75bhp jets. This is common on turbo'd cars, and can vary based on the turbo size.

I run 75bhp through a progressive controller in my 1.8 bravo. Which is a great deal more than I have heard people suggesting. I keep hearing this figure of 33% of normal bhp is a limit for NOS. I would say that applies in a fixed hit (on or off) scenario. But with a controller you can increase jetting ratio over time so the power builds up as your car reaches higher in to the rev range. This is guaranteed to reduce clutch and engine wear, along with allowing a higher max power application.

If you have any questions you could drop me a mail...

I have been running my kit for over 2 years now and speak regularly with a group of nitrous users on various different cars and setups.

The bora looks great with the mods you have done so far. Hope this nitrous venture goes well.

Also you shouldn't need to spend more than £1000 on a single point injection kit with progressive controller and bottle heater.

Cheers,

Dan

NOS recommend a 30% bhp increase for most applications, but obviously this can vary depending on the vehicle and other performance upgrades.

Fortunately for diesels, ecu remapping increases the gains from adding nitrous where as it is not recommened for a remapped or chipped petrol engine. The new intercooler will help matters too!

I've just checked on our price list and the parts mentioned above will cost you round about £750 from us so not too bad at all. We can also offer some other alternatives such as our new Pressure on Demand kit which comes with a bottle heater and remote bottle opener which is mighty handy! You could also add an intercooler spray bar kit too which aids with the cooling should you wish to up the boost on your turbo a bit. Plenty for you to think about nitrous wise anyway.

Forgot to mention Ian, Docking Eng make custom cooling systems so no worries about having to choose one yourself!

y'know, i was thinking about the 105 TDI passat i'm getting next, and while disppointed that its a 105, and therefore doesn't remap above 150, the idea of taking it above 200 using NOS did enter my mind. That way, when you are showing off a bit, you can switch on the NOS, and have 225bhp and stupid torque, whereas for daily driving, you can have 150bhp and still have tons of torque.
Ideally you'd start with one of the 2.0 lumps and not the 1.9 though. afaik some of those can already map up to 220ish, then nitrous and accessories (intercooler, BMC etc) can take you to over 300.

RR just likes revs. but some of us have figured out how to drive on the torque figure instead of using vtec at 8k revs etc. impessive, yeah, but i prefer having the fuel economy.
anyway, we're talking about powerful daily drivers here, not trackday wonders. though, if my passat was running 300bhp i'm sure it'd rule the trackdays as well as the chav-days in RL. of course, i'd be the muppet starting all the races with the corsa chavs, haha.
