APR DTR6054 Direct Turbocharger Replacement System

[El_bigote_AJ]

okay... those have got to be the worst logs I've ever seen in regard to DATA the horrible bit/refresh rate of the system you are using to log mixed with the lack of parameters its useless aside from knowing its actual psi stays in line with its requests. During the actual pull you can only see 3 snapshots of data really @2700,4400,6600rpm's

at face value 27psi tapered to 23psi when they shut down (early) - the numbers look good.

the numbers from that XL on the same dyno - clearly had some issue though... cause an xl even only 27psi would make at min. matching number and if it was with a DP - no question higher peak tq esp. since peak would not have been really fuel limited with an hpfp.

I didn’t even want to post them they’re so bad. At least they prove i didnt have a boost leak. I rushed setting up the logging in vcds, but I have no idea why the data is so choppy it looks like it didn’t even rev all the way because that data was cut off

VCDS is an amazing tool, but a poor logger generally. The rates can be slow even with a few parameters. Most likely the cause.

I still nominate @Patrykd07 as thread MVP for showing up with actual data.

 

[GTIfan99]

Doesn’t e85 rob low end power for top end power? I understand it’s small amount, but with concerns of the turbo lag?

No

For those of you that actually have this kit installed what are the highest boost pressure spikes your seeing.

Apologies since I'm trying to catch up and I'm confusing the different setups in here, but isn't that Golf R running the fueling stuff as well? Wasn't the base GTI without fueling supposed to be hitting 400? Shouldn't the R with fueling be hitting higher (I guess it actually could be taking into account all dynos being different)? Not doubting anything or trying to be combative, I'm genuinely lost in the weeds after 194 pages at this point haha.

Golf R is AWD, more drivetrain loss.

weeds? You've entered the forest now, son.

Seriously thankful I've kept up, we're on post 2906. 2803 of which make comment to pole dancers, tourettes, spaceballs, ghostbusters... did I miss anything?

Someone please start a GoFundMe for whomever condenses this into spark notes

haldex loss is pretty minimal, it disengages once you're moving, especially if it's not tuned. maybe 20-25hp loss. but the R fuel system is definitely beefier.

This specific case the Results are with the car on fwd/dyno mode.

That said doesn't the Haldex clutch pack disengage the propshaft at the rear axle, i.e. there's still some windage loss from spinning the propshaft even in FWD mode? Probably small but I imagine that adds some parasitic drag
