I'm reluctant to do any tunes. Once you change the way the car operates by
increasing performance or heat, then you lose the 10,000 mile extended oil
drains. I only use Amsoil and you can easily go 10,000+ miles on an oil
change. Amsoil won't cover the warranty if I do tuning and then something
happens. Everything stock causes Amsoil to warranty all parts and labor if
their oil were to cause any issues. It also reduces or eliminates oil
consumption from turbo usage.
I understand your concern about the oil change intervals. The thing is if
you drive it like you stole it then perhaps you are right about doubling
your oil changes. If you just use the tune to better you freeway on ramps
and merging or just to overtake a vehicle when passing then your oil change
intervals should not be affected.
It is unburned fuel. The turbo isn't pulling in enough air vs. the amount
of fuel coming in. It could definitely be tweaked to smoke less or not at
all. The 2012 TDI has a much different setup and you probably wouldn't see
any smoke. You just have to discuss your options with the tuning company.
Not the warranty on the car, the warranty on the oil. I will have to do
double the oil changes. It costs me about $70 per oil change. In 100,000
miles that's $700 for oil changes. After tuning it will cost $1400 every
100,000.
Why all of the pollution? I would never buy a diesel with all of that black
smoke. My 2012 TDI doesn't make any smoke at all and I want to keep it that
way. So if I put the Rocketchip that will make me pollute?
@twowheels87 It probably isn't much faster! It's an ALH engine. I've never
done a 1/4 mile with it. I have a VNT-17 turbo with a 2.5 inch straight
pipe. The clutch is from a VR6 engine and I upgraded the axles to Raxles.
The injectors are Bosch .216s. I'd say it's reasonably modified- not crazy!
It's been a blast to the power out of a car that still gets 45 miles to the
gallon driving like this once in a while.
Its very difficult to tell. But it doesn't seem That much faster than my
stage 1 '06 Jetta TDI.... do you know your 1/4 mile time? What turbo do you
have? What other modifications do you have? Is it the BRM engine? Sweet run
btw...
@dankcorey2424 Thanks! Yeah, smoke went away when I got a new mass air
flow!!! I didn't realize it was what was robbing all my top end power. Try
running with it unplugged... then you get some smoke! :D
Some stomp and go fun in my 99 A4 Jetta TDI. Injectors are Sprint 520s from kermatdi.com, and the chiptune is RocketChip Stage III. The car has 212000 miles ...
My friend has two TDI's. One MKIV and one MKV. I've driven the MKIV and it
really pulls hard. Spins the wheels on summer tires even in second. The
Unitronic chip gives more HP than the Rocketchip but it's up to you which
one you'd like to get!!!
That thing is pretty damn fast even with all of those miles on it. I'm
planning on getting a rocketchip stage two or three and bigger injectors in
the near future for my 2004 tdi. How much did your setup cost?
Isn't unitronic based in canada? I would probably consider it but i don't
want to send my ecu away or drive really far. Jeff from rocketchip lives in
the same state i do so i think i'll drive up to his place.
very nice but a highway pull on those cars is what really lets these tdi's
shine ;) pretty much the same setup as my golf tdi STOCK CLUTCH
ERRRRRR!!!!!!! but a very very nice car for the tuning needed.
Does this have a solid flywheel? If it does, is it lumpier when changing?
Thinking of getting a solid flywheel if/ when mine goes. Also, whats the
bhp on this after the modifications?
A solid flywheel, at least from what I've heard, is a pretty good idea. I
put the VR6 clutch/G60 flywheel setup in mine and it still feels stock but
can hold that extra torque.
Very cool video, does your TDI smoke a significant amount, or at all after
doing those mods? Also, did your gas mileage go down a significant amount?
thanks in advance!
It has a solid flywheel now, it didn't when that video was made. The only
big difference I notice is that it is a little less smooth when taking off
from a stop.
@Sanscho90 Stimmt nur bedingt, ein Diesel kann genau so hoch drehen wie
heutige sogenannte Hochdrehzahlkonzepte. 8000 RPM sind drinn. Das Limit bei
Dieselmotoren ist die Einspritzpumpe. Wenn die genug fördern kann, dann
hält man mit einem 1.9TDI locker mit einem Porsche Boxter S mit. Mehr als
6000 RPM lohnen sich aber nicht, weil sich die Kolbenringe sehr schnell
verabschieden. Natürlich ist der Motor ab 5000 RPM nicht mehr effizient.
HAHAHA most ignorant post ever. Maybe you should be the one doing some
research. A tuned TDI with a mild turbo and injectors is over 300ft/lbs of
torque any day of the week. They have 155ft/lbs stock. With just a chip or
injectors it's closer to 200ft/lbs. Put the 2 together and you're at around
260-270ft/lbs. VR6's or 1.8T's will never have as much torque per HP as a
TDI.
the thing is that a 1.9 tdi doesn't need a intake. with all the money you'd
spend a a intake, you can just change your injector nozzles for .205(for
example) for 50 150bucks and install them yourself one afternoon. basically
is what im trying to say is that a nozzled and chipped tdi is good for
250wtq, at not even 2000rpm. the week side to those is the clutch if
anything
Actually, you are the dumbass. When a diesel hits RPMs like this the power
output is higher than what a petrol engine of similar caliper would put
out. For example, the HP/torque output @ 5300rpms would actually be higher
than a similar petrol engine at 5300 rpms. or even 6000 rpms for that
matter.
dunno, seems wayyyy to high for a diesel, unless you modified your head, i
mean look at the r10 tdi, they only rev them to 35-3700 at most!, theres
absolutely no point in revving a diesel that high, you'll just burn your
valves. WHERES THE OVERLAP!!! lol maybe i still have some learning to do.
much people are my opinion if i read your cmt`s... a diesel engine works
from ~ 1500 - ~ 300 rpm, not over 5000... my opinion is that you should
wake up with a spade in your face every day... thats the same what you do
with your engine. look at my first comment and the green thumbs up...
Clearly this isn't a stock car. Lets not pretend we know what has been done
to it. The Sidewinder S10 revs to something astronomical, like 6k RPM, and
that's a Duramax. If you look up "450bhp golf", there's a mk2 golf TDI,
with the ALH engine in it, revving to 7.5k RPM.
@louisp12 TDI's were developed for the AutoBahn. They were intended to be
driven hard, with spirit! I FLOG the every living hell out of mine at least
twice a week. Redline or a smidge above in every gear!!! Yah gotta keep
that intake soot free:)
@problemkindtdi no,fuel type doesnt mean it should work on a certain rpm
range.build with a big turbo to provide air in the high rpms and it will go
up there.there are even diesel 6cyl mercs having 6600rpm rev limit,because
they are build so.
um....yes you can. i think you need to do some reading on TDIclub....not
just on Vortex. Read what members dyno with tuning. These cars are quite
undertuned from the factory...leaving lots of "play" for the
aftermarket...;)
Many of us with heavily modded TDIs routinely rev to 5-6K as the stock
valvetrain is good for it before the springs begin to bind. Getting the
fueling at that rpm depends on tune and state of injection pump as well
fast diesel.. but i alwasy wonder why ppl do this to their tdi. why not buy
a 1.8t and put the same amount of money into it and have 250HP and 300 TQ
rather than 140 HP and 200TQ
