View Full Version : .205 Injectors
has anybody upgraded their standard .195 cylinder injectors to a .205 or even .216 set of injectors. having recently just upsoluted i have been recommended to upgrade the injectors for an extra 20 - 25bhp increasing the acceleration ratio. if anybody has done it i am interested in where you got your new injectors from and part numbers. I know that you have 3 identical injectors and the fourth has a sensor on the nozzle, but could do with a website or other link for more info if poss.
cheers all

see www.tdiclub.com - Its american though and their cars differ as they are all 90BHP as opposed to 90 / 110BHP in Europe.
I thought 110's had .205 injectors.
Also, I think www.dieselgeek.com has some info and www.centralvwaudi.com may also have some.
Are you saying I can get a further 20 - 25 bhp on top of the increase UPsolute gave..... i.e, I'd be pushing out 174 - 179bhp???
neil, the situation is the 90bhp tdi's come standard with 0.184 injectors, and can be upgraded to either 0.195's or 0.205's, now i am unsure whether or not the leons come with 0.195 or 0.205's anyway, so in your case the increase wouldn't be worth the outlay, cos they cost approx £450. but if you want a contact number where you can buy a s/h vnt 17 turbo and intercooler for £350 give me a shout cos that will probably give you 20 or so bhp increase. but with that cost come installation which may be a couple of hundred quid unless you do it yourself, but for another 20bhp it is well worth it!! i was considering the turbo and the injectors but i haven't got that kind of cash laying around at the moment, but it would have given a total power/torque of approx 165bhp/320lbs/ft!!
enough to tow an 18 wheeler!!!
big smile on face!! but i'll just make do with the injectors me thinks!!
bye

Mmmmm, 320lb/ft, mine was giving out 253lb/ft when i first had the chip, and it was shuddering like anything. The 5 speed gearbox is only rated to 210lb/ft as it is. they had to reduce the low end torque slightly yo over come the shudder.
I see from TDIclub that dieselgeek does a VR6 clutch and a lightened flywheel. (www.dieselgeek.com) but if the 5sp Gearbox is only rated for 210 lb/ft then this will become the weak point !!
Where did you get the info on what the gearbox was rated at ?
:)
if your clutch judders, just upgrade to a sachs powerclutch which will take approx 300-350ft/lbs, your standard clutch should take 250ft/lbs, although you might get a little slippage in colder weather, but nothing to be worried about. if your flywheel shatters, upgrade your clutch, average price £200-£250 installed.
;)
what causes the shudder ?
DM Flywheel, clutch, etc ?

the flywheel can't handle the stress, therefore slippage occurs, once slippage has occured it glazes the flywheel causing it to further slip, therefore the more slips happen the worse it gets until you get well p1ssed with it and just upgrade. or, where the flywheel comes in 2 half moon pieces, the strain from the increase in torque puts an increased amount of pressure on the clutch at peak rpm (usually 2000 - 2500rpm)can cause the flywheel to vibrate considerably, which will eventually 4uck it up. so you upgrade to a clutch that can take the increased pounding. look at this link on tdiclub and the guy shows how you can upsolute and upgrade the injectors with no cause for concern. he is even considering adding a tuning box and running tests on that as weel, the nutter!!

This differs slightly from my understanding.
I've searched for a thread where langers gave a good explanation, and a link to tdiclub, but I can't find it :confused:
Upping power on a TDI110 has the following problems:-
1.Gearbox is rated to 210lbs.ft ~ there will be a big safety margin in here, so not too much to worry about.
2.Clutch can slip under the torque loading.
3.Judder around 1600rpm can occur on "increased power" cars due to the dual-mass flywheel.
Flywheel is in 2-parts - outer (drive to gearbox)and inner (drive from engine) are joined via springs in the same way as a clutch drive plate. The aim of this is to reduce vibrations ~ which it does nicely. Downside is that springs are obviously chosen with spspecific operating conditions in mind ~ it appears that increasing torque (by whatever method) by a significant amount around 1600rpm either causes fflywheel to go into harmonic oscillation, or (more likely since you've not changed the natural harmonic frequency) that power strokes from the engine are just too much for the springs and you eeffectively "bottom out" their travel.

210lb/ft is specified by VW. Also, to back this, look at the specs on certain cars.
The PD models with 5 speed boxes have 210lb/ft on 115 & 130 models, the 6 speed versions have 229lb/ft torque, with the 150 version having 236lb/ft.

rhiger, could u tell me more about this s/h vnt17 turbo and intercooler , would it fit a 90 bhp leon ?? if so wot sorta power gains would that bring along with .205 injectors then chipped???? cheers
fitting a vnt17 is possible, but getting the electronics for vnt control right is one big hassle. I still think it's easier to get the 90hp turbo turned into a hybrid. You will then need a good map to make use of the added boost your now able to have.
have a look on www.centralvwaudi.com
but if you want a contact number where you can buy a s/h vnt 17 turbo and intercooler for £350 give me a shout cos that will probably give you 20 or so bhp increase.
:cheers:
My understanding is that the vnt17 may handle more boost than the vnt15... but it won't increase hp by itself. If you chip and go with even higher sized injectors, issues could create turbo-splatter. ;)
it will give you an increase, but not in the same way as a petrol. If you run more boost for a given amount of fuel, you'll run lean and the motor much hotter.
Diesels don't suffer as much from heat soak either.

i upgraded to 0.216 injectors purchased from centralvw when i had my ibiza 110tdi sport. I had it remapped by upsolute but it would shudder at low revs and the clutch started to slip, ended up selling them. not worth the hassle.

How much were the injectors?

think they were about £450 brand new from central vw

yes, I'm looking for a new (to me) clutch and G60 flywheel before I can do any more. they're not terribly expensive here if you can find one...less than the labour to install anyway. I would think you could fiddle around in VAG-COM to fix the shudder though. Maybe not, people more knowledgeable would know I suppose. Take a look at the TDI-FAQ doc on tdiclub.com.
