Here is my ongoing project for my 2002 VW Jetta 24valve VRT..

Motor from a 2004 GTI-24valve VR6 w/ 6speed manual trans
Stock 2.8L bottom end
Head Gasket Spacer 9:1 compression
R32 24 valve Head with P/P, 5 angle head job, titanium retainers, stock valves/springs
Garrett GT3582R w/ .68AR
Custom AWIC system
Custom C2 Software
415cc Injectors w/R32 Fuel Rail...-6an inlet/outlet
80mm Hemi Throttle Body

Boost will probably be limited by injectors for now...
Daily boost will be 13-15psi
Track/Dyno boost will be max. 20psi
Horsepower will be somewhere over 400whp

single meth nozzle will be used right before throttle body
old Snow performance pump being used
Labonte MAP based progressive controler
using OEM washer bottle

suggestions on nozzle size?? I want something that will work for my daily excercises of 13psi, as well as something that will still be adequate for Dyno/Track days of 20psi...

D05 Nozzle should cover you to 20psi

shouldn't it be called a vr60?

[Snowman81]

Why would it be called VR60? I guess the 2.8l bottom end plus the 3.2 head? My head goes to the machine shop today...Mostly stock valve train from the R32 plus a set of Titanium retainers, a slight port and polish, and a 5 angle head job. The big build should start by the end of this weekend...hopefully pics will be posted in a week or two...
I ordered the DO5 nozzle from you guys, as well as the new check valve and the nozzle holder. This will be plumbed into the system right before the throttle body. I figured the DO5 would be about right, but wanted to ask the pros...thanks for the help.

In Japan they call me Oyaji, which means an old man, based on the bad jokes I tell. It would be a play on VR6T, the T being turbo, but the 0 in 60 would be the same sound as the T in this case

[Snowman81]

I still dont understand the 0 to 60 being the same sound as the T...I figured you were adding up displacements from the two engines....Do you have any knowledge of VW's VR6 engine? It is quite a remarkable piece of engineering. These blocks can reach around 500 wheel horsepower with stock internals and just a headspacer and beefier head studs.
The name VR6 comes from a combination of V engine (German: V-Motor) and the German word "Reihenmotor" (straight engine). The combination of the two can be roughly translated as "inline V6 engine".
The configuration can also be described as a "Staggered Six", in keeping with the geometry of the Lancia Fulvia staggered-four developed in the late 1950s. Staggered engines are an amenable further development with both uneven cylinder numbers and with staggered-bank V configurations.
The VR6 was specifically designed for transverse installation in front wheel drive vehicles. By using the narrow 15° VR6 engine, it was possible to install a six-cylinder engine within the existing Volkswagen four-cylinder model engine bays.

This engine is a beast even in stock form...and I can't wait to hear my 24valve scream with a GT3582R on it.

6 = six
60 = sixty
sixty is read six-t therefore, by sound, 60 and 6T are the same

Oh I see....sounding out my project...VR6-T or VR60...sorry bout that. I guess I am not all that awake right now.
I am currently researching what kind of fluid to use in the Air to Water intercooler....A friend told me I could run 100% methanol in my AWIC tank and lines to cool the boost most effectively. But I am a little scared of running a 5 gallon tank in the trunk, a large radiator up front, long, hard lines inlet and outlet, and very large intercooler under the hood all filled with flammible liquid...so maybe a 50/50 mix of meth and distilled water....
My meth injection will be using the OEM washer bottle and will probably be closer to a 60/40 or 70/30 mix of mostly methanol...this is for cooling extra boost mostly...probably set to come on around 9 or 10psi and go to 100% by 14lbs. Good for track/dyno days mostly, as my intercooler system should be more than sufficient for regular days of 12-13 pounds of boost.

I think good old coolant/water would be the best bet. I don't know if the methanol would be okay with all of the metal in the system.

[Snowman81]

if methanol is used with aluminum heads, i dont think the aluminum hard line in my system would be bad. My pump is a Mezierre pump that is meth compatible, and the radiator and intercooler can also handle it. I only have one piece of rubber tubing running from intercooler to radiator-everything else is aluminum hard line. The rubber hose is meant for all liquids.
