Took it for a test drive and HOLLY!!!! Had to do tuning mainly to te fuel table. Did she like the Race pipes? You can hear it.
I thought I had my GoPro recording!!!! I got back from the test drive to find out I didn't recorded it!!! i Was so mad!!

Since I'm running DIS, I threw a Firebird intake on my motor and it was easy to bore it to 59-60mm. I made an adapter to use my L98 twin 48mm throttle body on it. I opened up the ports on the inside edge to allow greater volume going into the middle intake. The middle intake is shaved down at the top and in doing so, the inside edge of the ports becomes larger/open there as well. The gaskets need to be cut/opened on that edge as well.
My 3.4 using DOHC pistons and Trueleo headers and a 2.5" exhaust outruns my 4.9 to about 75mph. Once you kick into 4th gear, the greater torque of the 4.9 will come into play and the tides turn. Still, for what I do - the race is over by then. You can see this here at the 18:55 mark of the video below where I am driving the 4.9 w/Allante intake 5 speed and a buddy of mine is driving my 3.4 6-speed. Tires are Toyo R888's on 3.4 and R888R's on 4.9. 315/35/17's. Another thing is it's much easier to launch the 3.4 than the 4.9... Anyway, the point of this is yes - there is plenty of reason to still want to create performance parts for the old v6/60.
Please take note that my buddy lost to the turbo AWD Dodge Stealth (w/3000GT nose). In this next video at the 15:11 mark, I beat that same car. The difference is I have an alternator switch and I disabled it every time I pulled onto the track. My buddy didn't for that whole race even though I suggested he should. He didn't believe it would make a difference. Back in 2012 or 2013, I dyno'd a +7rwhp and +11 ft*lbs gain after tuning for 12v with a bad alternator. I'm running the 7730 and there's a table that adjusts injector pulse width to battery voltage. So my a/f ratio basically remains the same except the alternator is just a pulley. As you can see, it makes quite a difference. From what I understand newer/modern vehicles modulate the alternator based on battery level. This is a performance/fuel economy feature.

I learned not to be a hater. The owner is a great guy and very humble. I believe he's only putting down about ~500. The 2011 WRX I raced afterwards that won the event dyno'd 287rwhp on a local Mustang dyno known as 'the heartbreaker' because it reads 15% below a dynojet. So that puts him in the 320-330 rwhp range. Again, really nice kid. All us regular run the 100 treadwear rated tires. Some us Nitto NT01's. You have to realize - nobody is "stock" there. The twin turbo v8 AMG is the closest thing to stock but even he upgraded his tires at the very least...
I was playing with tire pressures that day, that's why I spun out in turn 4 against the WRX...plus I was pushing it hard all the way thru because I know how good he is...
In fact if you watch the Labor Day video, the driver of the white EVO is who was driving my 3.4 in the Nutcracker video. His EVO dynos in the 800 hp range but he detunes it to 600 for this track. He does a lot of 1/4 mile events... If you listen to the announcer, his name is Kenny Kline...
here's a 9.3 run he did in 2016...
