So, why doesn't FP offer this setup but configure it with the IX comp housing? That would be a standard 71HTA but with the Ti-Al turbine wheel.

 

If there were any left, yes.

Nobody else is worried after seeing FPs video? A bit of spool at that risk? No way, Jose.

 

Keep in mind the shaft speed will be lower on the fp 71hta compressor wheel at 24psi versus an OEM Mitsubishi turbo sporting a 16g version. I agree with a previous guy above that you should be fine at 25psi +/- 2psi or so. If my kamak 9 blade sts turbine lets go this was the next on my list. I love quick spooling turbos that can make 450 (crank). No lag, instant boost.

 

My RS(non-USDM model)came with the faster spooling, higher shaft speed even than the TME 10.5, JDM RS VIII MHI Ti-Al 9.8 turbo from the factory.

That turbo, lived at 27-28# peak while preloaded to 23#, for 25K miles on Mobil 1 0W-40 .

Eventually, I sold that turbo and it was still running strong the last time that I checked. So, no need to get your panties all bunched up IMO...FP not withstanding.

Maybe FP is just making that product liability disclaimer to cover their backside. Maybe their units aren't as reliable as the original MHI Ti-Al turbos. Who knows?

 

From what I can see in the vid, it's an issue with the material, not so much manufacturing.
Usually a vendor won't advertise failures, weaknesses, and add disclaimers all over the place for something they sell LOL.
On one hand, it seems even they don't trust it. On the other, why would they sell it, if they didn't?
at first, I assumed it was a disclaimer as well. Just in case. though I wondered why the turbo would need one. Kind of like the "for off-road use only " kinda thing. but then I see they went to the trouble of making a video.

I personally have no experience with these turbos. But if those that has owned them say they are good, then I take your word for it.

 

Part of it could be the heavier compressor wheel puts more load on the shaft and turbine..

 

It's lighter. Just more fragile/brittle.

 

The billet, and larger, FP HTA wheel is not lighter than the oem wheel..

 

Eh. I'd try cryo-treating the wheel and not be too worried about it. There is also an HTA71 turbo with a Ti/Al hotside on FP's site. Kinda tempting lol

 

Cryo treating doesn't keep the wheel from flying apart due to centrifugal force pulling it apart..

 

Maybe not, but it should make it stronger, i.e. more reliable. How much more reliable? Who knows. At least it's not a magnesium comp wheel. Those things blew up like crazy lol.

 

oh, i gotcha. i thought it was. so it's more brittle AND heavier? yeah. no thanks LOL

that would be nuts. i could only imagine. magnesium wheels used to scare the hell out of me LOL

 

They're talking about the turbine coming apart, not the compressor. The FP compressor wheel are stout pieces. A lot of the really high numbers you see from FP turbos is guys pushing them to the edge and the turbo stays together. An FP red spiking 38-40psi and holding 30+ out the top is a good example of that...lol

 

I would be willing to bet the billet HTA71 wheel is not more brittle than a cast OEM compressor wheel.

Actually, I was talking about the JDM Evo 9 GSR magnesium compressor wheels coming apart...

 

FP = the ti/al turbine, Erik = the compressor, yes. so far i'm following along okay. i think LOL


i dunno. i've only read up on the ti/al turbine wheel.
