MK7 "Random / "Stupid" Questions Thread"

Not sure on that heim joint bolt - but Those are the incorrect specs for the 2 bolts that thread into the trans housing

You are going to snap the bolt or tear the threads if you do that since it’s not a strong steel material you are bolting to its 37ftb +90 degrees for those bolts if they are stretch. If they are not you really shouldn’t go much past 40

I believe the two bolts that thread into the trans housing are 50nm + 90degrees. At least what Racingline provided.

Edit: not sure if we are talking about the same bolts.

Does anyone know the torque spec of the bolt/nut circled in red? I need to use the OEM transmission bracket and VWR supplied bolt.

Sadly that bolt doesn't have a supplied torque as it's part of the pendulum support itself. It comes as a whole from VW.

I appreciate all your help. Puts me in a little bit of a pickle. Wonder if I should try the 65ft/lb.

I usually go with gütentight for most bolts.

Unitronic's similar product. Torque spec for Unitronic's arm mounted to the OEM piece is 75ft/lbs or 100nm.

Making permanent residence in this thread until I'm comfortable with my fueling set up.

If I understand correctly, the PR fuel line kit can either run directly to the fuel rail of an MPI set up or to the HPFP if not running MPI. So if I'm not running MPI this kit will just connect to the existing rubber line (highlighted in red) correct?

Is there no existing upgrade for this rubber line besides making it myself? Is it worth it?

 

[Diggs24]

The line has a threaded fitting so it can only go on the end of a PR MPI rail.

 

[Ezekiel81923]

They sell a barb adapter so that you can run it into the stock rubber line, just not sure where or if that rubber line can also be replaced.

 

[Diggs24]

You'd have to replace the barbed fitting cap on the HPFP to something else which will be no easy task. Not sure what you are trying to do.

Im confused, you have a link to this PR fuel line kit?

"If you do not have an aftermarket MPI, then you will need to purchase an additional fitting that is -6 Male Flare to 5/16" hose barb and utilize the rubber portion of your OEM line to finish the connection."

Then you could change out the HPFP cap.

And then I guess I'd have to make lines. It's a lot, I get it. Probably not worth it if you're not pushing max power. Was just curious if the fuel lines really only make sense if going MPI

I can just run the PR lines into the stock rubber hose like they suggest and the stock rubber hose remains secured to the stock HPFP cap. Seems to me like upgrading 3/4 of the line and keeping the existing rubber hose to the HPFP still creates a restriction of flow.

 

[Diggs24]

What kind of hogass turbo you running you need new lines for? And if you are running a huge hogass turbo you aren't without MPI so you won't be going directly to the HPFP anyways. No need for lines.

Hypothetical tune and performance consistency question. Say I have a solid tune for 91. However, I notice it pulls timing and feels less responsive in the summer due to higher intake air temperature. Would using 93 octane fuel without changing the tune mitigate this somewhat?

no

Lower intake temps is the resolution to year around consistency - ie: put the car on drugs
