I have searched, but i have read many conflicting comments. So..........

Has anyone with a 10.5 inconel turbine wheeled turbo upgraded to a tme ti-al turbine wheel?

If so, could you please note your impressions, feel free to elaborate.

I am struggling right now with the decision to just install my 10.5 housing or 2 buy a tme to go along with it.

Is the extra cash really worth the response you get from the ti-al turbine wheel?

someone sell me on the tme or steer me away!

what benefits am i overlooking of using the tme? is it just response, more linear power delivery as full boost is achieved, etc?

btw, i understand tme's come with 10.5's, i just wanted to clarify my comparison.

 

A $250 10.5 housing will do more for you per dollar than a full TME. The TME will not make more power - it will just give better spoolup. Also, the TMEs have the old dual-flapper wastegate design, whereas a new 10.5 should have the improved single-flapper design.

 

as b/r, works, and other's said. there is NO difference in the dual flapper to single flapper 10.5 hotside. no gains or loses in eather. there the same thing.

 

Thanks warralton, i am on the same page as you for thinking only boost response, however, i have never a tme powered car, so i am hoping there are people out there who can offer their experience of switching between the inconel wheel & the t-al wheel, while keeping smilar turbine housings.

I have driven many 10.5 powered cars after cam installs, but never 1 with a tme.

The only gain imo, which is unproven in effect, is the single flapper valve surface area is less than the dual flapper, so in theory, with the same w/g actuator preload for both, the single flapper system's backpressure opening threshold should be increased, thus helping you run/maintain a higher boost pessure before the w/g opens. My guess is minimal, not huge.

I have come to the above conclusion with the help of coor's vision

 

I haven't seen those comments, Evodan. Please point me to them. The WG design is improved, but that doesn't mean you have to see peak WHP/WTQ gains for it to provide more area under the curve.

 

i called b/r and spoke with dave and jar and they bouth said the same thing. there is no difference. i had pm's from dave saying this as well. no difference. if you pm me your email il send you some pic's of each one. works also said the same thing. the only difference between them is one is single one is dual. lol like mitsu is trying to save on caust or something. this is what i was told buy the same people you have spoken to.

 

n/m i deleted the email.

 

So is it possible to make 400whp with the 10.5? With Alky and high boost? Just trying to get my ego dyno pull. I just want to have 350whp for DD.

 

Yes.

 

My experience with the tme has been rather interesting. The boost response is VERY fast. It reminds me of how some Saabs are, just much faster on the top end. I get into full boost at in 2nd or 3rd at about 2800ish RPM (25 psi). The even crazier part is that I live at 7600ft altitude and the STOCK 9.8 did not spool until 3500rpm!

I am sorry I dont have dyno #'s but I assure you it is really torquey, and holds 20+ psi at redline even in first. I have done a roll on with another '03 evo (9.8 hotside) with more mods than myself (just not the turbo) tubular manifold, IC piping, above and beyond my mods. From a roll on from 10mph in 2nd. I was into boost at least 1 full second sooner and I pulled a solid carlength instantly. So yes the turbo comes on line very quickly.

Now for the bad news, the turbo comes on really quickly. Going from 0 to 25 psi in under .5 sec makes for a rather jerky ride. All the torque makes my passengers look like they are at a Slayer show. It is impossible to drive smoothly on the highway if there is an incline, the car is either at 0 boost or 20+ psi even at 10% throttle. If you are into auto-X I dont think there is a better turbo available, it does call for some compromises on the street however.

 

Now that is funny!

How much re-tuning did you have to do with this turbo? Were you able to just plug and play, as so to speak? Where did you purchase it from?

 

Exactly! I accidentally spit some food out when I read that :).

 

Thanks for your input tinytim

 

TME has 10 to 15 extra WHP than the 10.5... dyno proven

 

Where is that dyno proven, Az3ar? I've never seen this nor seen it claimed. Considering it ALSO is a 10.5, that wouldn't make sense. The compressor is the same size, but has lighter internals. Show us the dyno comparisons...
