Black magic Mk5 GTI track car

yeah they seem to be capable of around 550hp

Ok guys, finally got to install the TT-RS LPFP with some minor modification of the floating mechanism. As many have had problems with it showing the right amount of gas in the tank, here's what I did. The 2 pumps have the floating mechanisms in a totally different position and the TT-RS one touches the tank wall when it's in the middle position. Therefore, I had to "shorten" the metal wire holding the plastic floater so that it would come closer to the pump and further away from the wall, without changing the min and max positions too much also. Not changing them at all was impossible but i kept the minimum exactly the same as before (that one is the most important cause it shows you when tou run out of gas) and the max position became 1-1.5cm lower which probably means I will still see a full tank when 5-7liters from the full tank are gone

1) the 2 pumps aligned in the same position you install them on the tank...as you can see the floater are in a totally different position

2) Original floating mechanism

3) Modified floating mechanism brings the floater closer to the pump and further away from the wall ... keep in mind this is the situation for my AXX GTI, other tanks may be slightly different !

4) Max position change between the old pumps. Originally the TTRS one was 0.5cm higher than mine, after the mod it was 1-1.5cm lower than mine

5) Heard some complaining about some electrical wiring connectors mismatch...for me all was plug and play here

Great job as allways Fuscobal, mine is a bit temperamental but the refuel shows at 45 liter instead of 50 which is fine by me :)
Still i might do this when you give some feedback on how this works for you 

[fuscobal]

Sure thing Danish. At 1/4 it shows exactly the same as before (that's what I had in the tank when I swapped the pumps). Will see what happens when I fill up !

[fuscobal]

Got the chance to floor it several times and all is ok, car is definately pulling stronger. Also, walked the car till the gas needle was close to 0 to make sure it indicates correctly and the car doesn't run out of gas earlier that shown on the dash ! However, I've measured 100-160kmh with vag-com and pulled 6.3s instead of 6.8-7s before changing the pump. Several years ago when the car was ok but 200kg heavier, I was doing 6.5-6.6s. I keep reading guys taht pull 5.8s or even less and can't figure why as all my logs look fine. This week I will go from my 2.75" 200cell cat Milltek to a custom decat true 3" exhaust and update the software (my Revo is perhaps the first version for stage 3 and is 5 years old...they ight have improved some stuff in all these years :) )

The new 3" decat custom exhaust :

It's 6kg lighter than my old Milltek (24.5kg vs 18.5kg), although it has 2 mufflers and larger diameter. The pipe has a 1.5mm thickness in both cases ! At idle and under 3000rpms it's very similar in noise to Milltek, then it gets much louder gradually !

PS : Made a software update and now the car pulls like crazy but couldn't measure anything since it was raining all these days !

That looks like a fin job on that exhaust and 6 kg is an impressive weight reduction!

Very nice! 

[fuscobal]

Yes indeed. Also, the exhaust piping is myuch "straighter" and is a true 3" which only uses straight pipe and elbows welded together. Milltek uses bent piping and in 3-4 places I've measured a reduction from 2.75" to 2.65". Knowing the smallest section gives the flow the increase in sectional area from 2.65" to 3" (outside diameter) is about 28% (calculated on the inside) !

  New exhaust looks nice & the weight saving is quite a lot - I know you love to shed weight

finaly some proper exhaust with no corners cut.

Very nice to see your car in it's natural environment  !
A few thoughts:
1. It seems that the car is puling like crazy! That WOT is clearly doing it's job.
2. There seems to be a lot of understeer. It is the car / the tires / the weather or something else?
3. You could buy some A pillar interior lining!
4. Lovely steering wheel. 
5. The camera should focus on the windshield. It is focusing on the center dash... I think you are lucky the videos are not very bad because if it would have been sunny you would not have seen anything outside the car.

Looking forward for some other videos!

Great video - great to see you blowing everything off the circuit!

Thanks guys. Rex, WOT box is much faster but must be very careful cause if your timing is not perfect you could get to 10.000rpms or slip the clutch at 180kmh as I did once. Those noises you hear at 3:46 are actually flames on my exhaust as spectators reported :) The car understeers pretty bad but pretty much all FWDs do that on this track because the corners are very tight on exit...you will see when you get here next year. On the other hand, I kept the ESP on which also brought more understeer !
