It is not a wastegate, or turbo issue. It is a manifold issue. The wg runners are in the direction of flow, but there is a divider that runs up to the WG valve seat, blocking considerable surface area. The divider must be thick or it will blow out. This divider seperates the pulses completely before the valve opens which helps with boost response. That manifold was never intended for low boost, per the original owner's intentions.
Best solution would be to put in a 1.1 bar spring, and run it at 17psi. If that is not an option, next easiest solution would be a more restricitive exhaust system.
If one wants to run low boost you generally need our new manifold design.

other wise your looking buying another wastegate and another manifold.
or at the very least cutting the wastegate runners off and trying to fit 2 MVRs on there.

Boost creep solved
I too had an ill conceived single WG manifold design with a Tial 44mm WG. It crept to 17PSI at 5700 RPM, 370RWHP. I considered a larger, 50mm, WG but my flow analysis showed there was no way to save the single design.
I cut and capped the single WG tube and added dual WGs. Routed the WG exhaust back into the DP "Remora" style. Problem solved.

i'm thinking this is a perfectly good manifold for someone who wants to run higher boost, as it's very high quality and well made (as is everything elliot makes, apparently), so i could sell it to someone who wants to make more power.
i'd hate to hack it up.
but i need to run low boost for track days. my FD is supposed to be a weekend/track car, so i need to keep the boost/heat down, especially with this small turbine housing.

Modifying your current manifold is not a hack. A good welder can do it, and you wouldnt even notice the job (or reconstruction); plus will probably save money and headaches once everything is said and done.

I know its easy for me to recommend solutions, since I am not the one facing the problem. The way I see it, you will spend TONS of money on a new manifold, plus another wastegate, and the turbo location is not guaranteed, meaning that you might have to redo the downpipe and the intercooler piping.

Elliot, ALL your manifolds i came across suffer from the same problem.. maybe you should look into understanding how the wastegate should be routed on a manifold before building another one ?

No I haven't seen his new ones neither want to go through the bs I went through last time. Money and a lot of time lost for no reason
Let me ask u this though.. do u have shares in turblown "engineering"?

i just purchased one of elliot's new dual wg manifolds and two wastegates from a different source, so i will see what happens. they look very nice and high quality. i may still be in the same situation with the downpipe, as elliot couldnt guarantee the block and turbo flanges were in the same location, but i will cross that road when the manifold shows up.

Jabocartmill. The problem is people.arent.doing research outside of this forum. There are dozens of other, more capable ,fabricators out there with cheaper prices. If you search here all you learn is turblown and Aspec. Its a bias.situation. I found me an ex full race.employee,by luck, to make mine.

^How is it biased if you're free to post a review here on your Super Spiffy Manifold? People can make up their own minds.... the more choices the better I say, with both ladies and manifolds.
P.S. For the record I've installed a Full Race manifold in the past and was very impressed

So how many customers got un-useable manifolds until he was able to perfect his product is the point. He might make a nice one now, but many people got less than steller parts after being promised the moon. It seems to be the issue the op is facing, he got something based off his reputation and has a manifold he can't use. I experiened similar issues with one of the companies mentioned here.
I still think he should re-route the waste gate so it will work with a single or go duals. As others mentioned its do able. Maybe turblown would help him out, or he can hide behind the "its designed for higher boost thing".

i almost pulled the trigger on a full-race manifold. i have heard nothing buy good about them running on piston engines (i'm assuming the dual wastegate FD piece is the same high performing)
this new Turblown manifold should have the turbo positioned very close to where it is on my current manifold, so minimal downpipe changes will need to be made, if any.

There better be some pictures when you get your new manifold on and buttoned up, hopefully the manufacturer has everything ironed out.

Too much work now that my problem is solved. It all came down to WG runner location.

I think the manifold manufacturers you listed should supply the flow analysis data to help support their claims. Otherwise, they are leaving it up to us to be knowledgeable enough to debunk their marketing BS.
Besides, it isn't that hard nowadays to make a flow analysis and show how efficient a design is.
Without supporting engineering data, buyer beware.

The OP wants a low boosting quick turbo running a 0.84 AR and then buys the wrong type of manifold and you think its the manufactures issue ?
Theirs different manifolds for different requirements. Their isn't a 1 manifold that does all. grow up kids.
#47
that turbos wayyyy to big for the amount of power you want to make, and unless you're revving it super high you're powerbands going to be pretty small. but hey i guess if you're happy, when the time comes to upgrade you already have enough turbo for 600+
#49
F**K THE SYSTEM!!
Umm when you learn about.other manifold fabricators aside from turblown,aspec,rx7store, hks&greddy then you can call me an idiot. As of now... your the idiot for not knowing more. And yes.. there are manifolds that do it all.dumb ***... low and high boost... what ever spring you put.on the.wastegae should be near the.boost of the manifold.. if not there a design flaw. Idiot...

You're incorrect. That is not a 600 whp turbo on a rotary engine, and it's just about perfectly sized for his goals. He can maybe step down one size on the compressor, I'm talking one or two mm. That's it.
