If I can get 1.6s 60' time, I'm expecting 11.5-11.7.
yea totally doable. With a stock 9 turbo e85 and 400hp Kou was able to pull off an 11.2 quarter. That’s with slicks all around of course. Learn how to use your Ebrake to preload the drivetrain.
Quick update: I ordered Megan tranny, engine, and rear motor mounts (I already have front motor mount). And I ordered Megan coilovers. This hopping has to end!
Just a quick update. Driving with a Gus modded oem DV is rough. It's all or nothing power and is frustrating to drive partial throttle. The worst is getting to speed where DV opens a bit early and car falls on its face.
Anyway, I switched in a Synapse DV. And wow! Car feels like stock smoothness driving partial throttle!!
So for you guys trying to mod your oem DV to hold more boost by drilling into the bottom diaphragm vent, don't do it!
And if you think Synapse DV doesn't work, it held 30 psi between 4,000 and 5,000 RPMs, where my crushed oem DV would spike and drop back to 28psi. And going to work this chilly morning, I engaged clutch in 1st gear at 1500-2000 RPM, and gassed it. Tires started squealing 3500-4000 RPM screaming to redline. Wowzers, that was FUN!!! This 71HTA is absolutely AMAZING down low and mid way!

Speed Density and a Tial VTA was the best modification I ever did. Drive-ability at partial throttle is N/A like.
My phone couldn't open your link but here are a few photos. I'm just using one port and haven't tried out the other yet. I know one is more sensitive than the other and both makes it most sensitive, but I will try all 3 combos later.

To be honest, I was iffy about this DV because the valve is open at idle. But after testing it, it dors work better because it idles so much better when you first get off throttle and engaging 1st gear from a stop is better too. I feel there is more instant torque to make engaging clutch easier. I'm not sure what people complain about on these units, but I'm digging it so far.
What was the turn around like with Arlington and your cylinder head?
I have mine off again because of a leaking guide or valve and I'm losing faith in my local machine shop up here in the bay. I have a spare 4B11 head I am thinking of sending off to a shop.

How was your overall experience with Arlington?
Hi Bryan,
As you know, I'm a perfectionist and before I went with Arlington, I phone interviewed multiple shops and they were the only one that satisfactorily answered my methodical questions. They are not the fastest shop that will turn your head around in a week because they don't and won't cut corners. They are the go-to shop of most racers here in SoCal and I trust them like they are my brother working on my engine. Their motto is "why do anything if you don't do it right from the start?"
Give them a call and interview them for yourself.
As for my experience with them, it has always been top notch and I will have them build my motor. I'm only waiting for signs that my engine is worn out, but it is looking like 5-10 years out, so I'm looking to build a second evo instead.
