That is the point

 

What size turbos will you be testing. I always thought that a built 2.3 and a Full Race 30R TS turbo would make an awesome daily driver and a great time attack/auto cross type vehicle. If the turbo you are testing is going to be larger, then most people would be taking it to the dragstrip and would want it tested on a 2.0. I voted for the 2.3 because of the daily driver/auto cross aspect.

Good luck,

Saw the turbo sizes posted at the same time I was typing. The 50 trim could go for auto cross and the 35 would be drag strip. You could go either way. Sorry, not much help from me, but most people do have 2.0's. (But i'd still love to see a 2.3 test)

 

2.0 for the vast majority of Evo owners. Most 2.3 guys already have upgraded turbos. Still waiting for the perfect turbo for my measly 2.0. I'm just glad a couple shops within 50 miles of me are toiling away making what I'm sure will be great new kits.

 

98% of the people on here have a 2.0. A 2.3 is a given on how many rpm sooner it will spool.

 

Please test 2.0L with GSC S1's or S2's. . .thanks!

Not as many people have built 2.3's, why are people even voting for them?!! lol, is everyone leaning out that much now!!

 

OT

Also, ever thought about exploring/testing a Twin-scroll Borg-Warner S256? I've always been curious to see what this mystery setup would do in the hands of a good tuner. Thoughts?

 

They are one of the profiles that will be tested.

 

At the present time we are sticking with the Garret Platform. In the future if time and the budget allows we may test it. It is a T3 based divided housing?

 

do the 2.0L.

 

Who cares about what bottom end?

I'd like to see you do the test with a open manifold and open housing and try a few A/R's on the turbine side... then run a very similar divided manifold and divided housing trying several different A/R's.

 

If you were in the market to build your engine, what configuration would YOU choose?
After answering, or thinking about the pros and cons to each then you will understand why I asked about the bottom end first.

As far as twin scroll A/R's and such....It is easier said then done. There are very FEW A/R housings that CAN and will be used for our test and final production. Getting your hands on certain housings is very difficult and could prove to be very costly. So after calculating what turbocharger and engine combination is most popular, we will decide to use a specific type of housing and centersection. An open volute vs. divided test is DEFINATELY going to happen. That will help US and the members here understand and prove what works and what doesn't. Not to say that others products aren't conclusive, but to give another perspective and analytical point of view. I mentioned this in a thread with AMS a while back.
Open volute housings are easy to swap and test, but it has been done before. The general majority will run a standard of .63 and a silent minority will run the .82 T3 housing. We already know the benefits of each as it isn't a secret to anyone.
Twin scroll/ Divided Turbine A/R's are very hard to come by unless we were to cast various sizes and do back to back testing. Unfortunately for a small company, that would require a huge budget, that at the present time, IMHO, isn't prudent or advantageous for any company or individual.

 

Make sure to include exhaust manifold pressure logging and different cam timing adjustments. These data will be highly informative to you.

 

u should test jun 272 cams and revolver cams. if u cant get a set of revolvers let me know cause ill be swtiching over from revolver cams to jun anyway

 

+1 Also, cams, headwork will also play role in this, as well as A/R size.

I agree with Scorke, I really would want to see both, but I want to see the 2.3, as this would provide the absolute best spool/tq possible.

You may want to consider, a second poll with what A/R & cams to run or provide as options, so you'll now what the general public is looking for in a kit & what other options to offer that potentially still be cost effective & in demand by the EVOM crowd.

Lastly the header will play a large role in the testing, so are you only going to provide one option?

Thanks-Big Boost

 

Hey DTM how much for just the twin-scroll manifold?

I have a TS GT3076R from ATP with a .78 twin-scroll T3 Housing...


thanks
