Gator_86_951

I was thinking of getting the lindsey dual port for my car. It is an 86 and for $80 dollars I get something that won't have any fitment issues.

I have a quick question, it seems like some of you are saying that if I upgrade to a tial wastegate that I will have to get some sort of a boost controller? I dont need to get a boost controller do I if i already have a set of chips that are controlling the boost, and cant you control the boost by adjusting the wastegate right or not?

Dual Port Wastegates need either a MBC or an EBC:



If you do decide to get a Tial, you need to install it backwards compared to the stock mounting position.

Um, $80? List is $399.

I meant $80 more then the $315 from myswiss.

I just bought a new Tial off a rennlister today for a good price. I can't wait to get it in.

Trackin, You're a bit misinformed but not way off. The chips have zero function when it comes to controlling boost. What they do is allow you to run more boost by removing the overboost protection in the factory chip. The boost is controlled by your LBE, Cycling valve and the spring in your wastegate. If you upgrade to a Tial, you can get away with no boost controller and just run the boost levels dictated by the spring in the WG. You could also use the LBE in single port mode. The best option without spending a lot of cash would be to go to any welding supply store and pick up a pressure regulator (MBC) for $20 and have full control of your boost levels as well as be able to run the WG in dual port mode.

By far the Tial is the best bang for the buck. While the Lindsey unit is a nice peice, it is more expensive and doesn't perform any better then a tial. Another consideration is you lose your core or pay though the *** for it. A stock 951 WG will sell on ebay for just shy of 100 bucks, Lindsey will give you a $90 credit towards parts for one, or you can hang on to it to reinstall it if you ever sell the car. At the end of the day, that's about $500 for their WG.

Take the Guru W for example. Essentially it is a cracker jack solution to a poor design and at the end of the day and still a single port WG with slower response then a DP. A few steps better then shimming but hardly a Tial or Lindsey DP. You pay $190 for the WG, and have to give up the stock one which could be worth up to $100. For another $30 you can have a solid dual port Tial. It's pretty hard to match the competitive price of the 38mm Tial.

I have the 46 on my car and installed a 38 on the car I built for my dad. Both units have been outstanding to this point.

Sorry Jeremy but running a dual port with a single solenoid will not gain anything over a single port wg combined with a boost enhancer except for the ability to control boost against rpm or gear or other fancy stuff that the electronics can do.
The setup with pressure on the oppsing side as in Hosrom's figure #3 will really only do the same as a boost enhancer. There is no pressure that's trying to close the wg since the pressure never can be greater on the top side port than on the lower port with this setup. With a dual solenoid EBC setup one solenoid can close of air pressure to the bottom port while the other is open for pressure to the top port and thus creates a pressure differential that holds the wg closed. When it's time to open the solenoids switch position. With this setup you can create pressure only on the side where it's needed.

If someone hasn't bypassed the cycling valve, then the KLR chip will control boost. Some aftermarket chips (for instance APE) change the signal to the cycling valve, others (for instance Guru) just modify the overpressure protection and let you use an MBC to control boost.

I still think that the best bang for the buck is to save up for a K27/6.

Someone please post a link to website with dual solenoid ebc's.

I have a DP WG but I also have the accuboost. Can I run a line back from the top of the DP WG to tie it back into the line between the banjo and accuboost? Would that have more response compared to just venting the top port?

hosrom_951

With all respect people, i think we should stick to types and comparing them as the thread stated.

Heck some people here are running the Delegate wastegate as well. I would like to see their views here on that particular wastegate.

Hosrom-
I believe his question was answered.

Gator, I got a Tial on my 86... no special flanges, just used the Tial stock ones and welded in some pipe. Cost $275 all up...

Tomas,

I would love to walk through this with you but I don't have much time today so we'll have to table this one for a bit. I am not wrong in this case and by your response I don't think you've ever tried a single solenoid EBC or really looked into it but it does not work as you stated and does provide closing force on the opposite of the valve on a DPWG.

As far as the chips go, APE uses a modified banjo bolt to control boost, not the cycling valve, Weltmeister uses a drilled cycling valve/shims, and they both have the over boost protection removed. They don't use the cycling valve to control boost. Danno posted a pretty in depth explanation on why this never cold be achieved a few years ago.
