I have very tight packaging and was wondering how close to fuel lines you guys have gotten with wrapped downpipes and been ok?

Black -10 & -8 AN lines, non PTFE.

I wouldnt want ptfe or rubber fuel lines within 2-3" of any hot pipes.

And if you did have that distance, I'd want a heat shield physically separating them too.

Could you do that section in hardline or add shielding additional to the wrap ?

A lot of heat will simply be radiant heat after shutdown when there is no airflow, and IMO nit'd take a lot of wrap toprevent that heat vs time.

That is the area of concern and where I have to run the downpipe.

I'd try and relocate the regulator honestly
With a heat shield there's a good chance it would never be a problem, but I still wouldn't risk burning it down

I'd be moving the regulator too. That looks like it will be really tight.

Silly question, but I guess you cant rotate the turbo V-band and mount the turbos lower ?

Looks like that would give a lot more room for a downpipe ?

My return is close to my 4" down pipe-I wrapped the pipe in that DEI stuff, and used the slip over stuff on all my fuel lines anywhere near heat-seems to keep them ok
I never liked mtg. a reg right on the engine, keeps it way to hot
Dual injs, you got some serious stuff, lol
That is tight

How does the ATI damper feel about being near the turbos/downpipes?

In e46 M3s when racing, or anything with extended high revs, they have to direct cold air at the crank damper to keep it alive. The damper heats up and the rubber breaks down and makes for a parts yard sale. Granted that's a rubber based one, not a fluid.

Can't rotate them out as they hit the grille, can't go down due to SRC clip design, Regulator has airspace and we have had no trouble with it there before. Balancers have always held up well for us even with turbos closer.

I will wrap all hot side and sheath all fuel lines in exposed areas.

wrap the headers in the DEI Titanium heat wrap,and then put that orange heat sleeve over the fuel lines. The sleeves looks fugly but rated at a stupid high temp. Its for sale on eBay NASCAR parts used all the time for the sleeve.
