Hell I know what that's like. I was raised in North Dakota and it felt like winter would never leave. In Denver we get maybe 10 winter storms a year and the snow is only on the ground for 3 or 4 days then melts each time. So I can still drive the Z around in winter at least.

Cant wait to see this. I wonder at what psi this will choke out the maf at.

Sasha, Could you make the pipes with the longer standoff if requested? I wouldn't mind a strip setting at 17lbs or so.

oooo gimmie gimmie. lol. Ill have results next week. It will take some time to retune the car.

Sasha,

Do you have a few sets of these made up? I would like to get one soon. My motor is going to the machine shop today.

Ordering more pipes today so I can fabricate a few sets. I think it would be best if these become standard in the kit.

I totally agree. Man, I came into the game 6 months too early..lol.. There have been some amazing revisions to this kit, which was phenomenal when it was at Rev.0.

Got the 3" in and tuned. The only real benchmark I have was a 80-140km/hr speed run with the racelogic VBOX sport what is very accurate and used by car and driver to benchmark their cars. We started out with a 80-140 speed of 3.92 seconds. After the tuning we were down to around 3.60 seconds. The car is much faster now that I can safely run up top. I ran the timing into knock and backed off about 2 degrees to be on the safe side.

The downside to you guys looking for built block setups and want to run over 13PSI of boost I think different MAFs are still going to be required as now I am sitting ~4.75 volts IIRC. I think anything over 14PSI will peg the MAFs.

For what its worth my K value changed about 15% from what it was with the 2.75" boost tubes. So its fair to say that there was about a 15% increase in flow around the MAFs with the larger boost tubes.

Dumb question #1. How did I push 11lbs of boost through just one of these on my 06 single intake 350?
Dumb question #2. Can we somehow use the 350 mafs?

Answer to question number 1: Its not boost your measuring its airflow. So that could be why.

#2 - You can use the GT MAFs that uprev sells if you need the extra room.

No dumb questions at all.

Thanks for posting the feedback Mitch. This is about what I calculated as far as flow increase.

This sure makes you wonder how some others get away with 2.5" charge pipes.

Anytime Sasha, shes much quicker and safer now.

Lower boost? and a ton of timing? That or everyone is pulling into their MAFs and no one really pays much attention to it and just changes their fuel comp tables to suit? I mean it works but man it doesn't leave much room for error. Maybe thats a contributing factor to many of these popped engines? Who knows its all speculation.
