Nice numbers! Looks like its still climbing pretty well, any thoughts of revving to 8 k? And did you do it interior swap?

Woah, VERY nice build! So sexy under the hood, looks very precisely arranged.

TWO DW400 pumps, holy crap! Are you using speed controllers or relays to run them sequentially or with speed control?

Ha, that's awesome. I've a long time customer down under that has built the same generation Liberty. Last I checked, I think it was running high 9's.

Such sleeper cars.

I rev it to 9500rpm at the track, no point on the dyno besides tuning.

Yes I did the full STi Interior Swap

I have a haltech elite 1500 and a DW400 but may wire in a voltage booster that only activates under "high" boost, my intended average power levels won't be close to what yours does. Going to do a single in tank for now with 8AN teflon feed and see what she can do. Again, very nice build. I like your attention to detail and the oil filter looks like serious business.

Build looks sweet, Steve!

Feel free to PM me if you don't want to muck up the thread, but i'd be interested in hearing how you have your breathers routed with the big catch can box over there only having what looks to be one line running to it.

Also curious as you can only see two large hoses going to it.

I tried to use a downpipe mounted exhaust venturi and run mine similar with the vents going in and the venturi line drawing from the can or aos, but mine didn't work correctly. I ran one using a 12AN size check valve and large hose to the venturi on the downpipe, but it wouldn't draw vacuum at all, even at high power output. It's possible the cracking pressure of the check valve was too high and the venturi wouldn't overcome it.

There are 3 total hoses connected to the catch can from the engine PCV. LH and RH Valve cover then large rear engine block breather vent, the can is baffled and vented. Also has a drainback on the bottom.
