I am happy to draw a line under our earlier conversation but I have some questions on your car if you don't mind

I know you said you are running a stage 2 file but do you actually have a HPFP installed ?

reason I ask is IIRC the old revo stage 2 file requested 130 bar and I thought the limit of the standard pump was 120

may be completely wrong here but I just seem to remember that

I can answer that as Bill is offline, APR HPFP, fitted by Awesome GTI.



Thanks

Be interesting to see if the old code is giving more fuel that a stage 2 without a fuel pump (if i am right about the OE figures)

I was under the impression your car was running the standard fuel pump bill. That's why I thought the readings for yours were a touch generous lol. I still can't get my head round the fact your car is making more power than the + guys. It just seems backwards if you know what I mean.

Remember it's only making more 'peak power'
Its one point on the graph, most likely helped along by the fact that its a low mileage, well looked after example, with sensible modifications, rather than turned up to 11

It has always been a strong performer, and I went to plenty of RR days with it, on varying dyno's for several years before it was sold on to Bill. I know Bill has done very little with it, other than adding wmi and making it run better by sorting out the intake gas leaks, than I ever could with my limited end user knowledge.

Not often it wasn't in the top group of TFSI's, that were of a similar ilk, uprated pump, intercooler, down-pipe/exhaust, intake and clutch/flywheel.

Not had a hard life at all, serviced regularly with no expense spared and looked after and cleaned with an element of OCD. :blink:

I've seen at other Dyno's, not just on that car but all my cars before it, if they get hot they tend to make more torque and less peak. But if they don't run hot they make less torque and more peak.

But what folks rarely see past is the 'peak figures' its all about the full curve, how it drives, where the usable power is. [B)]

less torque on mine (ignore the spike) so it sustains its torque longer as it does not drive its cyl temps as high so it clings on to its ign advance holds the torque longer, hence makes more power..

As I have said earlier, drive them harder with boost for higher torque mid range, it will always tend to fall away with revs as temps (cyl temps) rise.

apr hpfp on mine, apr fmic, apr downpipe & cat, miltek catback, revo/B5 intake, devils own wmi on vag screenwash (neat), CTS discharge pipe, added preload to actuator.

In the tuner debate that is apr vs revo (all sigh here) there is the push for them both to compete for the "faster" car. APR are running higher mid range boost and will have more "shove" and torque in mid range.. BUT at the expence of this higher torque falling away sooner.

Question is on the road performance where you want the "shove in the back" feeling, the APR will kick harder than the revo ones, as they are driving more boost to produce the higher torque. Side effect is heat

6 of one, half dozen of the other. Different approaches from the respective tuners

As an observer of on the road and track tractable power however, mine spins up and smokes its tyres in dry in 3rd with the lower torque I have, so god knows how the higher torque leons find traction. "smokin...." :)

have a look at the logs done and see the aits logged from cars with wmi and without... and the corresponding power/torque differences..

Heat folks.. Its the enemy

eg my car... with more boosts... more heat, no more torque.. car rejected it..

Ah meth i forgot about that

do you have a lot of your fuel requested and actual ?

This is just for sh1ts and giggles... Comparison of 20v stroker on k04-023 hybrid next to high boosting Cheungys TFSi K04-064

Hold that boost baby, let her rip!
haha

Red = TFSi
Blue = 2ltr 20v
20v-16v-strokers-k04s.jpg


TFSi with same spec K16 clipped turbined, 7+7 BBT would be an interesting hybrid to compare. If it can do this on a stroked 20v what could a TFSi do...

I am on the fence currently on what the TFSi manifold/hotside will flow, vs egts vs backpressures... Compared to upsized large bore k04-02x ecu/manifold combinations.

I do wonder about tfsi rods tho at this level.. makes me nervous.. :hide:

give me a reason why I would want to reply to this..

I'll catgorise it as my opinion.... but keep it to myself ;)
