Simplified Sequential OR Full Non-seq...?

Now repeat after me... whether. Do you even have a high school diploma?
I still have my boubts as to the actual noise increase after removing the door.
Like I said. when I did mine (BTW Who did your the first time Jim, You or no?) I ported teh engine so It was louder anyway. There was no way to distinguish how much noise was caused by the removal of the door.
Mypoint is that the poor mans version of non sequential is NOT noticeably louder that the sequential. I also state that I doubt that removing the door alltogether increases the noise level to a considerable amount. However I agree that I cannot say this in certainty without once again completing the full version on someones (Jon you interested?) car and taking note of the changes.
"True non sequential" is a nice little cathc phrase you came up with but the fact is that the poormans version opperates the twins in tandem which is non sequetial.
Wether I removed all the parts or wired teh door back the **** is still non sequentail. REALLY, HOW **** CAN YOU GET? "It's not true non-sequential" LOL Give me a ******* break!.
If you go back and re-read this thread, you'll notice that both Kevin and I said after removing the gates. This has long been considered to be true non-sequential. What part of that didn't you understand, and what rock have you been under for the last several years? This isn't something I just came up with.
Do you understand that they call wiring the gates "poor man's non-sequential" precisely because it is NOT true non-sequential? How much more dense can you get? Sorry, how much more dents can you get?
If I ever get around to converting someone elses car to the completed full non sequential again and I do notice an excessive incress in noise levels then I will be back for my humble pie. Until that day comes.

Well having just done non-seq as discussed in the above mentioned stupid argument, I must say I like it.
I've had sequential twins for the duration I've had the car and the change was exciting and makes it a new car in a sense because it's something new. It was a small concern of mine originally not having the quick spool of seq turbos but it's really not as bad as a lotta people seem to think it is. I have an open exhaust and I spool pretty quickly IMO. The main trick was just staying in a rpm suited for boost when I thought I might need it.
The fact that there's no transition is great and the fact that I can get better gas mileage when I want by staying out of boost is just another perk in my mind.
So if you have any other questions that you want an opinion on in regards to how my car / turbo's act with non-seq let me know.

OH BTW there is a rather large difference between wiring a gate open and cutting it out. In its open position the gate still poses a rather large obstruction to flow. Pull off the manifold and put the gate in the "open position" and see for yourself compared to the pictures Jim posted above of a cut out gate.

When I converted my open exhaust car from sequential to poormans nonsequential it got SUBSTANTIALLY louder. SO much so that I was then forced to go buy a presilencer to weld into the MP, I couldnt stand the added noise. I imagine FULL nonsequential would be even worse as far as noise.
perhaps the noise isnt so noticeable on a car with one or more cats or restrictive mufflers.

I have a quick question. Why would you go through the trouble of porting and rebuilding the motor just to run the stock turbo setup? What kind of horsepower are looking at by porting and using the twins?

Then what are you basing your statement that there is no noticeable increase in noise on?
So now you're starting to change your story because you realize you might be wrong...
Maybe I should buy you a spell-checker instead.

Enough for high tens in the quarter at 125MPH. That's of course with true non-sequential, also with trimmed exhaust wheels and porting of the manifolds and turbos, not the motor.

I had no problems controlling exactly 15psi of boost with "true non-sequential" ported engine and unported wastegate. You wanna argue that too?

Here's a picture of the first, taken at Jim Dagley's house in August of 1997.

I dont think he said boost creep was a figment of anyones imagination, I think he just said there are ways to avoid it. I have almost the same setup Dave had when he was non-seq, same ecu and the same boost controller and I hold constant all the way up the rpm range.
And who "invented" this that or the other thing is pointless and all just something that's your assumption. Unless you have a patent on the damn thing its pretty hard for you to know if someone hadn't done it elsewhere prior to you. So let's at least stop that bitch fest and get back to our other worthless arguements.

I guess non-sequential boost creep must be a figment of everyone's imagination as well. You're right, we're all just making it up, just to **** you off.
I did not say that boost creep isn't for real. I simply said that I never had any boost creep on my car with full NS, straight exhaust and a street port. All done without porting the wastegate, imagine that.
I am glad to see that you take credit for doing so little as saying " hey I larger hole would help" Way to pat yourself on the back there genius. You even went through the trouble to find a pic to post. classic!!Hey Jim, it sunny by my house right now, You wanna post a pic of your house to prove that the sun isn't out

Actually Jon, I had the full version on my car. I also never experienced any boost creep and get this. I didn't even port the wastegate!! HOLY ****, The sky is falling!!!

Well no **** you won't have boost creep at 15psi! What made you spit out that outrageous comment?
Most people get creep when they try to maintain stock boost. I never had any creep when I set my boost to 12psi with a ported engine and all bolt ons. But 12 is the lowest I could go as it would creep back to 12 again any way.
