Anyone know about BR's new TD-04? Supposed to be 9mm bigger than a 19T wheel? WOOT!

[UTRacerX9]

Hmm... I remember all the old stories about the GT368 turbos being "too large" for the turbine they used, and were unbalanced. If these turbos are truly that big... well then I guess the old thinking of pairing a large compressor wheel with a tiny td04 turbine needs to change. Or possibly GTPro was simply slapping together a crappy turbo and that is why they never lasted.

What was the compressor wheel average on that setup? Wasnt that still smaller than a 19T compressor wheel? There's 5 people in my local chapter running 368's and none of them have problems aside from a couple needing more tuning. Was there a problem with them at one time or something?

[UTRacerX9]

A lot of people grenaded their cars because of 368's, they fell out of favor pretty quickly, but in the old days, there simply weren't that many turbo choices available to us. Both the turbine and compressor specs are bigger than the 19T specs, according to Stealth316. The common theory was that the compressor wheel was simply too big to be matching with the turbine that they chose, and as such, quickly became unbalanced. This may be true, as the "T" wheels are lighter than the old turbo wheels of the past, so going with a bigger wheel now may be possible with new turbo tech. At any rate, there was a long list of people who had 368's that needed to be rebuilt and eventually gave up on them.

Just talked to Mike over at Blouch and he won't release any specific spec information on the the wheel. He did mention current turbo tech and touched on how the upgrade is possible. As you mentioned UT, Mike stated it ties back to adequate pairing with the turbine wheels. You can run a bigger compressor wheel then what was once percieved if you lighten up the turbine wheel. In this case the compressor wheel must be paired with an HL wheel, and only an HL wheel or something lighter.

We also discussed critical pieces of the setup and prevention of stall and surge. I mentioned to him I had surge problems awhile back and resolved them by utilizing a combined "Y" junction for my turbo intakes. I revertwd back to the stock bubble with hard pipes having and fed them from the same source and dramatically reduced surge. The second thing I mentioned to him was changing the routing and diameter of my intercooler pipes into the intercooler core. I changed the piping to equalize the pressure differentials between the two. That was critical.

The wheel does exist, and the upgrade can be made thru Blouche. Mike will not release any information on them other than "the compressor wheel is bigger than a 16g, it's billet, and it has been tested and proven to flow between 35-37 lbs per minute.

From what I could find from the CODSM turbo tech archive the flowtest results on an MHI 16g place it between 26-28 lbs per minute and the EVOIII flowtest results are in the range of 38-40lbs per minute. Now you really can't compare the two because on one hand we have a TD-04 housing and in the other we have a TD-05 housing, they are different frames. In terms of airflow volume it puts this right smak dab in the middle of the two.

The cost for the upgrade is $900 plus an additional cost associated with a rebuild should any bearing wear or seal damage be present. Grand total with your own cores he mentioned would be rougly $2500.

Signed, stamped, delivered, 100% TD-04 bolt on setup. Takes 7-10 business days to turn around a set.

Hope this answers some questions out there folks.

Thanks for the info.

Now I just wonder how this compares to the Dr-700

[J. Fast]

I've never ran a DR setup or seen any actual lb. per min. results on the 700 series turbochargers. I can say I've ran a Blouch setup and had tremendous sucess with it. Same goes with Forced Performace. Either of these retailer produce excellent turbo's and should have a similar performance expectations with the emergence of new turbo tech.

The DR TiAl turbine is obviously a step above an HL. No one to my knowldege other than DR will ever produce something like that for such a small frame turbocharger.

The spool time I'm less concerned about as I can manipulate boost onset with some trick tuning using a standalone, give it a little more pep with some manifold port work, and ofcourse do some headwork.

[markoverclock]

the billet wheels on turbochargers.com flow 32-35Lbs min. for the 3000gt, they also have a td05h-18g and 20g.
Both of those compressor wheels have the evo 3 cores on the compressor wheel for a lighter wheel , quicker spool, and more flow than the traditional mhi.
I was told they will be on their website shortly as its in stock just needed to update the website.

So you mean these

[J. Fast]

Is that link for a distributer or a builder? Are these your builds overclock? I have never heard of this vendor till about a month or so ago when someone posted a link. Anyone used them before? Are they reputable? No offense if this is your company marc... just never heard of it or seen any reviews before.
