I've done 10.787 on the 1/8 mile 12 years ago on a much heavier B4 Passat, smaller injectors and dead stock turbo...

Nash_TDI · Apr 24, 2015

I ran 9.76 last year in my mk4.

dogdots · Apr 24, 2015

I ran a 5.95 1/8th years ago - on my GSXR with nitrous

I always wanted to make a few passes on my hot rod Jetta TDI but our track closed in KC before I got around to it

Put o2 wide band sensor and check if you are too lean or not.
If the chip are done correctly, the air/fuel ratio keep same at 25psi and 30psi.
Street, between 16:1 to 18:1 air/fuel is pretty good for power with low smoke.
Drag, between 14:1 to 15:1... is possible to have small power gain with 13:1-13.5:1 but with lot of smoke.
Over 18:1, no smoke but less power, if you have smoke, the trouble in injection system.
Under 15:1, to much smoke for daily with Bosch VE pump, is possible to run 15:1 with not too much smoke on common rail injection because better atomisation and injection control.

Original intercooler is not the best choice for high pressure setup like you.

Will do I'll buy one that logs. I could use help on finding a rpm signal tho

rpm signal? for the AFR gauge? you don't need that...nor one that logs...

i was thinking of using it to capture information for a tune. im used to going to the dyno for a tune when something is changed. not sure how the chip tuning can be 99% correct, surely there is a margin of error seeing as all setups are not equal. any how a $160 wideband with bung bought.

Stock intake manifold? Curious how much of a difference the PD130 makes, if you happen to try it. I cut my spare in half so I cannot check...

you know the intake has never been off the engine and has had a egr operating for the last 200k miles.. so much to investigate!

i see that the pd130 is a slight gain. and the pd150 is a better mod. seeing as mine is infact plugged up ill look for a pd130 or pd150 thats already clean and swap it out.

Stealth TDI · Apr 26, 2015

Darn! I had high hopes for the GT-2052! Here are my best times with a K03/K04 hybrid, PP502 injectors, an RC tune, a CAI that I eventually removed, and (I think) a straight pipe:

Car #1801

AThreeTDI ran that day, too. His car was identical to mine except for having a stock air filter, Malone tune and (definitely) a straight pipe:

I'm curious to see if the GT-2052 can pull a higher trap speed in the full 1/4-mile. Any chance of you getting the car on the 1/4 mile?

Scott

1986.5supra_kid · Apr 26, 2015

the closest 1/4 mile is quite a far drive. the 8th is where i am every thursday. and yeah i would like to try better tires and launch harder. also stock trans and i feather it for minimal wheel spin in first. who knows maybe its a tired motor.. has tons of blow by,unless oil all threw the intercooler is normal.

malone tune did feel stronger on the gt15. limp mod engaged with the gt2052 on the malone tune but still felt strong.

SkyRyder55 · Apr 26, 2015

from what i understand pd130 and pd150intake are the same. different side for intake port direction.
A plugged up stock intake will make a big difference.
Oil in intercooler is normal(ish).

GTiTDi · Apr 27, 2015

Scott, don't be bummed by his results, stock head w manifold that has never been off. pathetic if you are looking for power. Needs to be ported these things are anemic stock! Not to mention he's running stock boost plumbing and intercooler. Tuned for a GT15 still.
Also don't forget, there are a lot of variations like driving ability, setup, and tires.

I wouldn't call these credible results

Digital Corpus · Apr 27, 2015

To note, my dynos are with the stock intercooler setup

those results are with mike @ tdtunings chipset for my setup. that being
1998 AHU
MBC
FMIC
GT2052
pp764
straight pipe
arp studs

setup being very stock suspension besides new control arm bushings,ball joints, 1 year old kyb g2 struts, brakes were checked for proper operation(no dragging pads)

Tires were not the greatests choice. but i never spun on the strip besides to clean the tire outside the burnout box. aired down to 20psi for a larger contact patch and aired the back up to 50 for less. all excess weight was removed(spare,jack,floor mats,rear seats thats it)

Nash_TDI · Apr 29, 2015

My run.

Stealth TDI · May 1, 2015

I focused mostly on your trap speeds. ET is an indicator of driver skill and initial hook-up. The trap speed between runs is usually very close unless the driver REALLY messed up in the first 60-ft... REALLY messed up.

I don't put a lot of stock in the "trap speed equals XXX horsepower" models for our cars. But comparing the trap speeds of similar cars is a great way to compare relative horsepower. My consistent 71-mph traps indicate that I'm making similar or marginally-more power than your 2052 car.

AThreeTDI's 74.9-mph trap indicates that he's making more power than me. My ride-along in his car showed me had he significantly more power than me. Even with me as a passenger, he still turned-in a faster ET and trap speed! I was hoping the 2052 would replicate that.

1986.5supra_kid · May 1, 2015

well i bought the pd130 intake and i plan to clean the intake ports of the head when it is installed. the plenum probably has some build up seeing as no one has touched it.

DJGonzo · May 4, 2015

You need more boost and more fuel.

Unless that's all that sucker can do? 17/22's can do more boos than that for sure

not sure if its something with the setup or possibly the tune but We shall see what the pd130 intake does and some cleaning of carbon on the intake ports of the head.

I see there are may methods of cleaning lol

SkyRyder55 · May 4, 2015

just be sure that the intake port you are cleaning has the valve closed. Then rotate engine as you go to other intake ports to make sure the valve is also closed.
Seems like a simple concept, but you know how people are...

1986.5supra_kid · May 4, 2015

i think one mentioned using hacksaw blades?

papasmurf · May 26, 2015

I used a 3/8th size cable. I used about a foot, cut off 1-1/2 inch of the sheathing and frayed the end. The other end went into an electric drill. Worked great but not ideal.

1986.5supra_kid · Sep 3, 2015

Ran again. 9.8 @ 70mph iirc

Edit: 71.2mph lol
I can only get 20 psi on this setup tho. Wastegate is secured to sTay closed. Buy I can't even over boost. Also added inline e pump

There, fixed it for ya.

Nice try. Mark Malone wrote that particular "Aligator" tune.
