Cant control boost

[nathanl70]

Yes,
This one is a Chinese Knockoff as well.

Got it to come down finally. Had to use both the top port as well as the bottom port. Will make around 10 lbs like that wide open. So I can use my boost controller on my top port to shut off the vacuum going to it to get a little more boost out of it. Thanks for all the replies an help!

Don't know how using the top port would aid in getting boost down.
To push the wastegate wide open, put full boost to the bottom port. The top port open. That would give the lowest achievable boost.

Those pipes require port work to both pipe and turbo to get control. Even more so with a oversize blow dryer.

My down pipe is the gn1 performance pipe. I looked in the ports for restrictions and saw none, and no hard corners also. I used the top port by putting vacuum to it. It must be just enough vacuum to keep the boost down enough to not need alky.

Please explain how you are achieving vacuum on top of the gate under boost.

If it was the same one I had, unbranded, cheap Chinese Tial knockoff, came with the DP. Sure does look the same.

Guy, Remember your original combination was with a smaller turbo & warmed over stock engine. You now have a much bigger turbo & a stroker motor hence more exhaust flow & a major change in the combination. Second problem is any external waste gate can seize from corrosion even the most expensive. Even though that GN-1 downpipe was going on two years old Archie bent over backwards to help make it right. He is aware of some problems & working on a redesign so I wish you would check with me before you post things like this. There is a lot of R&D that goes on with the vendors that supply these parts that we are fortunate to have. The T/H style D/Pipes which have also evolved aren't always available either. Sometimes you have to work with what currently was as in your case. The point is when you bash vendors it serves no purpose except to discourage progress to solve these problems. Before any of these aftermarket D/P were available I use to build my own. It took eight hours of labor to cobble something together that would work . Thats why I appreciate the fact that I can now buy something that sometimes not perfect i can at least work with to get the car out the door. Your car is now fixed & the combination brought up to date so it works. So I'm giving you a shut up stupid & don't drink & post !

I'm new here and not trying to start anything or piss anyone off, but I for one want to know where the strengths/shortcomings are on any product whether they are a vendor here or not.

How is a vendor going to make improvements or redesigns without ALL feedback of said product. I'm all for freedom of speech as long as it isn't malicious and can be backed up by facts, and in this case on this persons combination, which might be similar to someone elses and they can learn what works or what they might be doing wrong or not even know what might be wrong until someone else who has been there can chime in with their experiance.

I'm all for not bashing someone unless the problem/customer is ignored.

It is very important to all involved [vendor and potential customer alike] to get as much feedback on any product, good and bad on as many combinations as possible, to see what can be improved/expected on said combination.

We all have opinions and those should be taken with a grain of salt, but facts are what I'm looking for and vendor protecting doesn't do me any good if I end up buying a product that doesn't perform like expected or needs me to further modify it without my knowing that before said purchase.

With the many different combos that these cars are running and how they are driven, honest real world feedback from real people using said product is still the best advertisement that any company can hope for.

Capitalism = Build it right and survive, if you don't you die and that is how it should be.

I'm not sure how it works with the top port putting vacuum to it but it does help it out a whole lot. But I also know that for vacuum brake conversion you buy the new top part where the vacuum lines go and pull vacuum from there to make them work. So if the vacuum brakes work from the top while under boost or driving around town I don't see why it wouldn't do the same to help pull the waste gate open. I used the vacuum port that goes to the canister on drivers side as it seems to have more vacuum then the port for egr, I tried both and that one seems to open the waste gate better. Does this make any sense bison? I know in theory it shouldn't make vacuum under boost but then why does vacuum brakes work with changing the top ports?

 

[TurboBuRick]

The bake booster has a check valve that will close under boost allowing retention of the negative charge.

 

[Hotrodbuick]

Never thought about the check valve (my car still has the stock brake setup) well that makes sense about the brakes then. Well I'm stumped on how the vacuum line helped open my waste gate.

This makes sense but wouldnt be repeatable if there were some leaks in the circuit or the vacuum reserve was less at a given time than another like if you were pulling from the brake vacuum reserve an applied the brakes and put the engine under pressure without waiting for the vacuum to recover. Some wastegates are orificed also. If you need vacuum on top and boost on the bottom to open the gate then the spring tension is too much.

Lou,

First, I wasn't bashing, as I said in my first post. I am accutely aware the effort and hours you and Archie expended to get my car right, but as you discovered after many hours of agonizing over the original downpipe combo, it just wasn't gonna work out.

Second, I posted up the solution you came up with as a suggestion for ROBZOMBIE to try if he couldn't get the current setup to work.

Thirdly, You have been, and continue to be one of the most genuine, staight foward no BS business owners I have ever met and I respect and admire you for it. I also am proud to consider you a friend. You've been nothing if not honest, kind and fair to me. You're a tough nosed mentor and I appreciate those qualities.

As to the "So I'm giving you a shut up stupid & don't drink & post !" If you look at the times of my posts, they were made during WORK HOURS, times when:

A. When I'm at work and jump over to TB.com for a little diversion , I don't have alot of time to tell a story, so most times it becomes the Readers Digest version, as was the case here.

B. I made an effort not to point out any particular vendor and didn't "bash" anyone in my post. I merely gave ROBZOMBIE an alternative to try if he saw fit.

C. I don't drink at work, so that bullshite was thoroughly uncalled for. We will talk about that in person.


This particular situation has been the one of the very few instances where you and I have disagreed on how the approach to a solution should be taken. I had one thought process that has been developed by my experiences as both a customer and a service/product supplier in some highly stressful atmospheres, and you had yours. Yours being approach it gently instead of with a full head of steam. In the end it worked out well for all and, as you know, I am extremely happy with the outcome.

There are many opinions, points of view and approaches out there as to the sharing of information on this board.

In this instance I respectfully request that we both agree to disagree and then just leave it alone from here on out, never to be mentioned on the board again.

I agree the spring tension is way too much, but I looked up an saw gn1 doesn't sell other springs and I have no idea what waste gate is on there. It's hard to take both hands and collapse the spring so I know it has some tension on it. I was thinking of cutting off half a coil at a time with just the boost reference line hooked up until it came down, but not sure that would work.

 

[turbolou]

If a manufacturer is selling junk & not backing it up go for it. Guy Cunningham is a cherished customer . I made a decision to try a GN-1 down pipe when I initially sold him a Regal with a stock engine. He contracted me & at that time wanted a hi 11's street car. At the time the only D/P available for months was a from GN-1. it worked well for almost two years on a four hundred H/P application. Guy now has a mid ten second car with a stroker motor. So everything has changed & some bugs had to be worked out. Now since its my rodeo not GN-1 or anyone else's I bear the responsibility to make that happen. Cunninghams problem has been resolved at no charge complements of GN-1 perf. because that vendor after almost two years came to my shop worked with me & went beyond what one would expect. He is now busy on redesigning his pipe to meet the needs of the higher out put cars which are constantly evolving. I'm also stuck out here on the West Coast & don't have the luxury of more abundant east coast support & have to work with what is available. So for Cunningham to come on here & make a statement like that hurts my ability to help him or others cause he has now probably without thinking alternated one of my suppliers for me. Who you MF on here today may be one you have to turn to later. I have had to eat my words a few times myself.

Shut up stupid citations are my trademark & cannot be used against me. As with any other disagreements we may have my opinion is always right but will extend the courtesy of listening before I ream you

 

[williamsGN]

You get what you paid for applies here, Chinese knock off wastegates have no place on a TB, unless you like repairing your car.

I have a 61BB from Cottons. Jack ported out the wastegate hole before delivering it. I have his 3" DP with a Deltagate and manual controller. I can turn the boost down to 10 - 11 psi.

As stated above, you're right.

 

[Hotrodbuick]

I have a old turbonetics delta gate I was thinking of putting on it. I know the spring in there is weaker which will be good for what I need. Tial gates are so nice but $$$$$. I don't plan on racing the car all the time, just a daily driver I want to run good so for now just keep my foot out of it and boost low until I can figure out the waste gate. The pipe is pretty nice and fits in my car really good, no complaints there just waste gate spring in it. Anyone have same downpipe and tried cutting off a coil or anything since you can't buy different springs.

 

[williamsGN]

Are you lowering it for looks or is this DP related ?

 

[Hotrodbuick]

Lowering what? Don't understand what you're asking....

 

[williamsGN]

LOL.. thought you were talking about cutting coil springs for clearance or something haha

Put the deltagate on with a manual controller and you will be set.
