I actually just asked him about the tme wheel, and he said it barely makes a difference, and that hes had the turbines shear off the shaft, so he doesn't like to use them

 

I've been running a TME turbine wheel in a evo9 turbo, here is my take on it...

During a WOT pull on 91 oct it will spool about 150 RPM sooner, injecting meth will accelerate this a bit quicker. Part throttle boost response is very quick & boost recovery between shifts is equally impressive, even when not using NLTS. When injecting meth I have been able to get this turbo to surge & recently installed the FAP compressor housing which is making for one hot little turbo, quicker spooling without any surge & more top end....I'm really digging this turbo right now

There are downsides as previously brought up, Robert has reported cases of head separation at high boost levels....I've been spiking 30psi for 7,000 miles so far on this turbo. Now realize this is not a daily driver, so when I pull it out of the garage it gets pulled out to be driven & is boosted to the moon the entire time....that's 7k of hard driving. Recently I had the turbo apart & inspected everything & all is well. This in no way means that it won't blow up, I realize that I'm flirting with disaster because of the boost levels that I run & am willing to accept the consequences.

Of course, then there is the price, $450 for the turbine wheel or buy a used 6.5 TME turbo & pull the shaft/wheel...I did the latter because it was relatively the same price as the shaft/wheel & gave me spare parts to rebuild the internals. With the added cost of the FAP housing I'm into it about $600. Is it worth it...I think it was. I know I could have had an HTA green for a few hundred more but I wanted to see what the evo9 turbo could do at our elevation.

Just my $.02

 

Thanks for the info on these TiAl turbines , its filled in a few gaps in my knowledge . Perhaps they were considered a consumable in the Grp A rally days .

I suppose the time a turbine wheel/shaft gets worked harder when a larger diameter and capacity compressor is clamped on the other end of it .

I wasn't sure weather FP was profiling their port shrouded compressor housing for the std 16G wheel and it occurs to me that it could be a way to improve performance everywhere without reliability issues .

Most wouldn't go looking for them but I believe Mitsy homologated a version of the Evo 6 TME turbocharger with a 15 , I think "T" , compressor wheel and you'd think it would get cracking early for a bush bearing turbo and especially with a port shrouded comp housing on it .

That 15T compressor is designed around a 34mm or 36mm resctrictor. It has a 65mm exducer instead of the typical 68mm exducer as well, it's going to make less HP then the standard 16G wheel. I'm sure it would spool faster though.

That FP ported shroud has me interested after Gearheads results... It falls right in line with what Aaron and a few others reported. If I can't break 400 on E85, it will be on my list for next winter.

 

I suspected that was the case with 15T compressors , I don't know off hand what the inducer diameter of the 16G wheel is but it must be larger than that 32-34mm .

I find the turbo restrictor engines very interesting mainly because of the phenomenal torque the factory rally teams got from them - particularly in Group A trim .
I'm not sure if anyone since has done much with these 15T TME6 turbos but they are probably a step in the right direction in unrestricted form if you want a small block Chev and don't mind it not revving so high .
The 65mm OD T wheel may be one of the reasons why the 4-8 type compressor housings stayed as they were and only enlarged on the 9 MiVec engines .

I don't suppose anyone has compressor maps for the 15T and 16G Evo turbos because it'd be interesting to know what mass flow they generated so we could get an idea what potential they have .
My guess is that they should have been good enough for the 206 Kw that the Evolution 6 had standard and with a bit more boost and the usual derestriction ie inlet and exhaust upgrades it couldn't help but be a Whippet out of the blocks .

The light TiAl turbine should get an easier time with the slightly smaller compressor and the comp may even eliminate the need for a port shrouded compressor housing .

The thing I'm getting at overall here is the chance to make stroker style torque at lowish engine revs without spending stroker type dollars . If you can get a reasonable serve of the stroker type performance with at best a freshened up 2L engine and a factory turbocharger its gotta be great bang for buck .

I think for some the wow factor in a sporty road car is watching soaring tachos and boost gauges but I'd reckon that a super punchy brutally torquey Evo would be too much of a handful to give you the luxury to look away from the road if you flat sticked it in the first two gears .

I don't know about in the States but here in Oz the authorities have just about every electronic biting aid available to nab us for speeding . I think a car thats a slingshot off the line and a rocket ship to about 60-70 mph or 100-110 Km/h here is the way to have some fun and not end up in the slammer .
If the penalty is changing up at 6500 or ramping the boost down and a few more revs then so be it .
I think at the end of the day its how adequate the thing hauls rather than numbers it generates .

Food for thought , cheers A .

 

This is straight off the EVO 8 16g I have sitting on my desk. All dimensions in mm.

Compressor
Major: 68.0
Minor: 48.3
Blade Height: ~21 (difficult to measure)
Hub Diameter: 14.6

Turbine
Major: 55.9
Minor: 49.1
Blade Height: 19.8
Hub Diameter: 16.9


TD05HR-16G6 Compressor flow map, ~44 lb/min max flow
I imagine the EVO IX cover (TD05HRA-16G6C) is worth 1-2 lb/min above this.


You sure it is a 15T compressor and not a 15GK2 though? The actual TME 6.5 is a TD05HR-15GK2 according to this thread:
https://www.evolutionm.net/forums/en...low-rates.html
I think the inducer on that turbo is 49.3mm? No idea if it flows more or less then the 16G6...

 

What boost level was this at?

 

27 peak falling to 21 is what the chart shows?

 

uh, reading the graph it looks like about 26psi?

 

Ah now I see...I was on my phone looking at this so it was unclear. Thanks!

 

Anyone run this thing! Ready to buy

 

Just ordered one. Should be here next week and then ready to rock shortly there after. Should be fun. I will post results once I get to that point.

 

if ur lookin for a noticeable upgrade from stock u would go for the fp green cuz it has noticeable gains. i dont see a reason either for this turbo

 

did you need to get anything else other than just the upgrade, i.e oil lines etc.?

 

no we did not, i wouldnt imagine that we would need them considering the stock ones work fine on the hta green. it should be in tuesday!
