The boost taper issue. Running high boost on the stock turbo or the 20g's and having boost taper is normal and it is NOT fixable. Yes, you can improve on it but it is not going to be eliminated. The boost tapers as the turbo cannot supply enough air to fill the engine and keep the boost up.

Yes, we can do a ti/al wheel, it is $200 more. The new 20G-9 when bought comes with a new actuator on it.

I wonder what would be a better gain overall.. ported manifold / o2 housing or a tial wheel?
You said the E9 20g with tial wheels are already in stock right? I'm not so sure I can wait til after christmas for this thing lol
I got the fever and the only prescription is more cowbell.. or a 20g

I'm sure he means a stock evo9 actuator. They sell a re-springed stock actuator for $175 (extra).

I moved the timing and AFR's all over the place and even with the improved boost level the power at 7,000 rpm stayed the same as the last graph I posted.
Hi David, I'm just trying to figure out the math here on the difference in roll weight.........
(3333.75/3400)*100=98%........
Your roll weight is 2% less than PD's OR PD's roll weight is 2% more than Davids.
How did you get 10%....

Our roll weight is set where it was when it was manufactured at 3333.75. Yours being 3400 is about 10% more roll weigh than I use, this will produce higher numbers, as you know. So to answer your question, that is how your dyno reads higher.
Thanks all,

The EVO9 turbo comes with a new actuator on it, not high boost.
The ti/al wheel is $200 more and spools faster, no down side to it. I have no ti/al wheels, we used normal turbine wheels in the 10 turbos we had to build. They will all ship by Wednesday.

Here is the deal and it sucks. The entire deal
We have 7 or 8 turbos that will be ready to ship out by this Wednesday. The problem is this. The turbos came in a lot earlier than we thought they would. In order to install the 20G-9 on an EVO8 you need:
Lower i/c pipe
Oil and water lines
That is what is in our installation kit for $140 (BTW, that price is going up as I never figured in the lower i/c pipe cost correctly. I am honoring it for these first 10 turbos).
Anyway, I called last week to order all the water and oil lines I needed. Well Mitsubishi doesn't have but a few. I have those coming and will be able to send out a few complete kits. The rest of you (we'll fill the orders in the order we took them).
This is the deal. I want to ship out all of these turbos that I had built. Problem is some of them are going to have to leave without install kits. We will ship and bill you for the turbos and then ship/bill for the install kits when they come.
I am sure some of you don't want the turbo without the install kit as it will be a shelf decoration. Anyone that doesn't want to take the turbo now will be put to the back of the list again as I will ship the turbos to anyone willing to take them NOW.
We will be trying to call anyone with a turbo on order to let you know about this. If you read this and don't mind give us a ring and let us know if you will or will not be willing to take the turbo while it is available without the install kit.
I have oil/water lines on order with Mitsubishi and have a request in for air freight to get them. No idea when they will be in.
