I purchased this as a "Q-trim". It should be large shaft with a left handed thread, 11 plades, etc.

However as you can see it is 10 blade, the outer edge is not "clipped" like a Q-trim, and the thread is noraml right handed.

Can anyone tell me anythign about this wheel?

From the seller after the sale:
"It is Garrett p/n #410982-0001 turbine wheel assembly and they are called a 75 trim from Garrett used in model #'s TW4103 and TW4105."

I need to know if I should use this wheel with my Turbonetics Super-H compressor (just slightly smaller than the 60-1). I'm looking for 400whp with the fastest spool possible. And if this is a decent wheel to use what a/r compressor is recommended and what should it be cut out for???

It would be easy to get these answers if I could contact Garrett directly but unfortunately they only show a list of supplier's, most of which were of no help to me, many where even quite rude!

Thanks for any help you guys can provide.

Tell them to measure minor and major diameters on the wheel.
That would confirm if it's a true Q-trim or not.

that's the weird thing I think the measurements are correct for a q-trim
maybe garrett q-trims and turbonetics q-trims are slightly different? But this has to have different flow characteristics than the turbonetics piece, it has fewer blades and a different angle on the blades

def not right, lol. It's not even a bigshaft!

Not a standard "Q-Trim" wheel. the standard comes "big shaft" and does come with 11 blades. All standard Q-trim wheels be it from Turbonetics, Innovative turbo systems etc are Garrett wheels and will all be the same wheel. Innovative does offer their own versions of turbine wheels as well, but they call them GT. Such as a GT N,GTO,GTP,GTQ, and GTR trims. These are proprietary Innovative wheels and have a 10 blade count and flow and spool quicker then standard Garret varients N,O,P,Q (Garrett does not offer a R trim). They also are available in Inconnel and the more exotic Mar-M materials and are big shaft in p trim and larger sizes.

Your wheel is a design from a turbo that was built with a specific purpose. Its from a turbo charger meant for a specific OEM engine. 410982-0001 Wheel-Turbine-Assembly is from the TC4402/TW41 turbocharger. Whats its meant for?? I have no idea. I assume a low production run for a specific desiel engine for someone.

Your going to have to get a turbine housing specially machine in order for that wheel to work assuming that it has the proper shaft diamter to even work with standard bearings. Or, get the turbine housing that came on that particular turbo (No, I have no idea on the foot print {probly either a T4 or T6} and have no idea on the A/R value either).I'd toss it, give it back etc. Its a paper weight.

If you plan on running the super h compressor wheel and your looking for "the fastest spool possible" and 400hp. Your going the wrong route. You'll need a P trim wheel or GTP trim to maximise spool and power. A Q trim is too large for the compressor your running. it will spool slow even though it will yield a nice exhaust to intake presure ratio. The p would be much more suited in size for quicker spool and may still net you 400hp (most likely need to be at high pressure ratios due to the smallish comp {17 psi +} and you'll be out of the comp's effiency range).

well I've since switched routes with my turbo project. I found a nice deal on a BB turbo with P-trim, and 60-1 Hi-Fi on the cold side. What's nice is that my nice anodized Super-H backing plate works with the Hi-Fi . Sound good for nice spool and 400HP? What size tang housing is recommended? I'd like to go with divided. KD street-ported engine.

Now I'm in the process of getting the seller of the mystery wheel to refund my money. Just so everyone knows his company is the one that redirects visitors of www.turbonetics.com to their website. The ebay name is turbos_r_us. They purposely mislead people. CAUTION!

The 60-1 sounds good for what your looking for. For a quick spool, a .84 tang divided housing will work well.

Just curious, who made the turbo? It is NOT ofered from Garrett with ball bearings. It would have to be from Turbonetics who offers a single thrust ball bearing, or from Innovative Turbo Systems who offeres a dual ceramic bearing system. Both turbo companies come with an anodized backing plate already if ball bearing. If its a Innovative BB turbo it will be purple. If its Turbonetics it should be gold, blue or red (im not sure which comes on the bb turbo). I know red is for a carbon seal standard shaft, blue dynamic standard shaft, and gold a dynamic big shaft (innovative uses big shafts on all their bb turbos) but not sure which backing plate Turbonetics uses on BB turbos, but I think its the gold.

So if this "BB" turbo your getting has a cast backing plate, it most likly is NOT a ball bearing turbo. Double check with the seller and find out who put the turbo together.

hmmm, that's interesting. You may have just saved me a trip to DC to pick it up. It's made by turbonetics, so it should have a gold backing plate just like the T04B (non BB) that I currently have.

nothing is working out with my conversion to single.

Well, if the price is still right, a 60-1 with a .6 A/R HiFi compressor and a P-trim .84 divided turbine matched with a divided manifold will still net you around 400 rwhp (probly less, more like 375~390) and have a decently quick spool dependant on other factors (porting, manifold design etc). the BB really offeres a 500 engine rpm quicker spool give or take 300 rpm dependant on other factors.

I've had people tell me .84 is too small for even the q-trim, I figured this would make it far too small for a P-trim. I had planned on a 1.00 divided with the P.

Look around, theres many making big numbers on a .81. Anything smaller I'd say it'll choke. But your specing "fastest spool possible" and a .84 is NOT too small. Theres pleanty running this turbine housing making 400 rwhp and more. 1.00 divided will work fine as well, but your giving up spool.

And turbine wheels should be spec to the comp wheel your running and intended purpose. Running a Q trim on anything smaller then a T61 (not to be confused as a 60-1) is just plan bad turbo building.

this is what everyone (including Turbonetics) is saying. This makes me wonder about the guy who I bought this from and whomever built it for him. Well anyway, thanks for your help. Hopefully with the help of all you guys I'll have a nice single turbo 7 to run someday!
