Then I imagine that you must have constructed the piping in such a way as to keep the pulses separated.
Ill be using two small, 35mm, watercooled tial wastegates to keep the pulses segregated on my new set-up. I hope that it sounds as good as your when its done. Thanks for tolerating my Q and A.
@originaldriver The two banks Y together right at the turbine housing inlet. There is a small pocket shared by both sides at that point. That is also where the single wastegate is mounted. Check out my other vids. There is at least one that gives a good view of the exhaust system.
@DonW21G I have a 60 degree 3400 v6 that I swapped into my 95 camaro, (now getting swapped for a built 3500 v6) that used a similar set-up and produced a sort of high pitched exhaust note like that. Still, it wasn't anywhere near that high a frequency. You must be using a split-pin crank as well. It sounds exotic!!
@originaldriver You're correct. I am using an even fire crankshaft. It is a split pin crankshaft. Balanced cylinder power, increased VE and even exhaust tone were important reasons for coming up with the exhaust system that I did. Thanks for the compliment. I like the sound too.
@DonW21G Yes, everyone knows about anti-lag I wouldn't waste your time with that. Go ahead and email me we'll talk about it. This will require to to buy another wastegate.
A most recent tuning discovery has made the need to raise the torque converter stall completely unnecessary. Check out my most recent video posted 7/31/10.

Sounds like your converter is still too tight and its very lazy off the line, we went through a stage like this some time ago.
With our 240z and a 182ci straight 6, we were able to hit the transbrake and get from just off idle to 6500-7000rpm with 30psi boost in just over 1 second, it then leaves hard and strong, have a listen to some of my video's.
Your 60ft will drop considerably when you get it to leave fully on song, best of luck :-)

Good grief!! How high is that thing revving?!
originaldriver 1 month ago in playlist Cool Turbo Buick Vids, V6 only-no hybrids!
@originaldriver The exhaust pipes make it sound like its revving higher. Redline is 7800 rpm. Shift points around 7400 rpm.

@DonW21G Then Im going to assume that you are using even length headers and a divided turbine housing, yes?

@originaldriver That's correct.

@DonW21G Tell me, are you using two wastegates or a single?
originaldriver 1 month ago
@originaldriver A single 60mm HKS wastegate and one Godzilla BOV.

Love what you do Don. Thinking outside the box when it comes to these old Turbo Bricks...

@DonW21G I know of a way you can spool that turbo with more boost off the line, with no nitrous.

@Nettikturbo Will it allow me to build 17 psi boost in 2 seconds without popping and banging?

Thanks for the insight. I'm still playing with the launch tune. If I run out of tricks, then I may throw in the towel and loosen the TC.

Thanks, kingots. I'd still like to get close to another tenth off the 60', but she's very close. Got some plans for that.
I'm very happy with the way she's running now.
