I would suggest that you do run a return scavenger pump with as low as those turbos are mounted. The oil would literally have to drain uphill to even go back into the pan itself. That doesn't make for good drainage out of the CHRA.

yea i may eventually move mine to that location, the APS kit takes the oil from the factory sender location, and then uses the scavenge pump to dump it in the oil fill spot. My oil pressure drops to 18-20 at idle when the car is warmed up and I only see about 40 at start up & wot.

did you have any problems with the pasenger side air filter pipe fitting. the instructions show it running in the same spot as the drivers side. right between the motor mount and oil pan. it wont fit there due to the tranny lines.

i think i can get it to run up behind the motor mount but was curious what you did on your car.

i want it to keep it as nice to drive as i can. maybe someday get into the 10's.

for now mid 12's or faster with no other mods than bolting the turbos on and tuning it, maybe some tires on the stock wheels.

i also have a TT G8, im at 7psi, and the restof my mods are in my sig. Here are my times from when i went to NED friday night for the street night, on my 18" all season.

fyi-this was my first time at the track, so you should have no problem being mid to low 12's

12.687 @ 118.3 first run ever
12.270 @ 118.3
12.503 @ 112.3
16.342 @ 87.8 last run with lots of wheel hop so i let off and i still almost beat a mustang lol

i am not getting this done quick enough. drag week will be here in no time.

all i got done since last week are the "down pipes". then i started looking at tieing in the wg's and they look real tight. if i could put them in backwards it would be easy on both sides but to put them int he right direction is tight.

car will be running stock 2.25" exhaust, stock cam, stock injectors and low boost. it should be quite a big quicker than mid 12's once i work thru some of that stuff. i figure injectors and cam should allow me to turn it up over 500rwhp but that is not going to happen right away.

The build looks great. I have a few questions, where did get the flange to bolt up to the stock exhaust, and have you decided on what oil return pump you will use?

Stampede.
