That would seem pointless because the extra power comes from the larger housing.

 

But it would spool O so Fast!!!

 

The turbo that i have been wanting people to try is the 2871R. its a hair bigger than our stock and many VW owners use it with there GTI's. It will have the ultimate low end, spool power for sure. I just wish if anyone had installed it???

 

Ted b., I am looking for torque right now! That's why I opted for the 264's & not the 272's you went for.

I have read good things about the 2871 too.

 

If I have a another EVO I would install the 2871 to see what happens but I wont change my 3071 at all especially after what it did for me last night against greened STI .


but I would love to see the 2871R in action.....

 

I'm assuming these gains are due to the larger 10.5cm^2 turbine housing.

From the comments above, it doesn't seem like there is a huge gain in power from the lighter titanium components. But is there a very noticeable difference in spool up and transient boost response?

 

no doubt the TME turbo in my opinion is the best turbo for the track (not QM track) the response is amazing and I am sure that the lighter shaft is going to help spool up no questions and give the driver a great midrange punch. The tracks here in the US are small tracks 2~3 miles not like Germany and Italy where u have a 10 miles track with 4 miles stretch.

 

For me, that is the million dollar question... Well, $550 question anyway...

 

Here's what's going to happen. Thursday I'm taking my car to the dyno to get a STOCK baseline. I'm going to remove my XEDE and put the factory air filter back in.

Then, in one of these upcoming weekends I'm going to install everything, send my ECU to Vishnu to be Xflashed, and then do a new dyno. I'll post the preliminary numbers as well as the post tune numbers.

This should be a great way to see how all this stuff works together without adding up hp claims one piece at a time.

No doubt, due to reduced back pressure, better cylinder scavenging.

The only power advantage of going with ti turbine wheel over the heavy wheel, with a similar turbine housing is from the additional boost you didnt have before @ a lower engine speed. Once both turbos are @ boost, they'll make the same power while everything else being similar.

I apologize for getting off topic earlier.

 

More power at lower rpm is good!

Transient boost response is how fast boost kicks back in after shifts or after you get off the gas and then back on it, like in an auto-x. How does the Ti turbo compare to the stocker in this area?

 

Also, remember it's the area under the torque curve that really matters for acceleration. Anytime you can boost earlier and develop torque earlier in the RPM range without sacrificing top end torque, you are increasing the area under the torque curve. So, a titanium wheel should effectively generate more area under the curve than a stock Evo wheel assuming it doesn't give anything up on the top end of the RPM's.

 

This has already been done by several of us with the 10.5t turbo, and we've posted the before/after dyno charts.

 

Gee Ted, thanks so much. I didn't know that so many people have already installed the exact same mods on a bone stock car then did this, who'd a thunk it?

I'd love to see your dyno sheets, in case you never read the title of this thread that's pretty much (among other things) what I was looking for. All of these several people who've already done it haven't really chimed in with numbers to date, but I will.

I know that sometimes a person's real meaning gets lost in translation on a forum, but that comment sounded to me like you were belittling my efforts to share with the group. I could be wrong, sorry for the tone of this reply if I am.

If I am reading this correctly, you are going to do a baseline, then install everything and redyno. Yes or no?
