Hi guys
I got an 86 5000 Quattro Turbo (10v) today.the car runs good and pulls clean all the way to 6000 rpm.I was just looking for some ideas to free up some more horses(that wont cost more than thecar)I am going to do plugs, wires, rotor and cap and change all the filters as a start.

Any ideas (yes I did search before posting)

What is the use of the hose that goes across the valve cover and down next to rad area?
Thanks

Its an air hose that runs to an electric blower motor which runs with the after-run system. Cools down the injectors/fuel lines to prevent vapor lock. Don't think mine has worked in years lol. Runs off of an air temp sensor on the heat shield near the wastegate. If it doesn't work I wouldn't be too concerned really unless someone knows differently?

It's a good idea to have the injector after run fan in working condition as it'll make your injectors last longer. Not a huge deal if you don't.

With the 10vt there isn't much you can do except find a chipped ECU. I mean you could solder in the diode or resistor (can't remember which one it was) as the cheap way to bypass fuel cut but obviously fuel cut is there for a reason, so you don't lean out too much and have pinging.

Just get a chipped MAC11. If you just remove fuel cut you'll probably blow the engine in record time since the A/F ratio will be out of wack past stock boost levels.

100% chip the ecu first.

Save the resistor mod for later on when you find a way to supplement more fuel. Strap the intercooler at this point, too.

Edit: I can't find any links that have instructions for the resistor and zener mod. It was years ago when I did this and and I don't remember which pins the resistor gets soldered to. You still might be able to find something on audiworld.

Intake and exhaust. Also boost gauge and controller looking to get rid of boost cut. Also jus got better controller one I have is cheap as f$*#
Hallman makes a boost controller that decent and not to pricy. Also i've heard mixed things regarding the diode/resistor mod. Make sure the engine is in good runninf order though, no boost leaks and such.
