I've seen it all now.
 

SSAC Substandard T70 on H22 with S2S2 cams, TT rods and Mahle drop ins; 332 wtq @ 5200 and 375 whp @ 6700 on 16 psi with a stock ITR fuel pump, stock pressure, 10 gauge wiring.


She started leaning at 6500, boost fell to 10 psi immediately at 7000, both put a damper on revving her out to 8500. Come to find out the compressor nut had fallen off and the inducer fins looked like a serrated steak knife; I could have stuck a finger past them and touched the inside of the compressor scroll exit. Wacky thing is, the car still spooled and created pretty good power although it was flat as a strap 5500+ right up until the damaged compressor wheel ran out of flow and boost dropped off.

edit: Dynojet 248C numbers, FTW!

Re: I've seen it all now.
 

Every one of those SSAC T70's are junk.

Re: I've seen it all now.
 

carnage pics?

Re: I've seen it all now.
 

Yeah, this is the third one that's gone on this particular car. I've seen one go 8K... all the others die within 250 miles. :l

Re: I've seen it all now.
 

A local shop to me had a garrett that had the nut come off also. Garrett is bitching about replacing it. lol.

Re: I've seen it all now.
 

Thank god I got the T4 60-1 instead of the T70 I was checking out. :P So is there anything preventative maintanence that can be done before spooling one of these up?

Re: I've seen it all now.
 

I suggest you preventatively round file the T70's, it'll save you a lot of time and effort in the future.

Nobody noticed this is on a stock fuel pump, all that surprises you guys is that an SSAC turbo failled? :S

Re: I've seen it all now.
 

i have the T70 on my mustang and its doesnt have a problem and its been there for a couple thousand miles.

might make a difference on how fast the turbo is spinning (eg making 16psi vs 8psi)

Re: I've seen it all now.
 

So I'm flowing 375 whp worth of turbo rpm, and you aren't, is the reason why it came apart? You mean to tell me Mustangs run 9 second 1/4 miles off sub-375 whp??







































Haha.

Actually, the compressor nut is a classic problem with these piles of ----. The first turbo died at 25 miles from just that, this one shredded the compressor fins because the nut kept bouncing around in the airfilter and trying to suck itself through. Harry at MR2GURU said he's seen three of them lose a nut, too. Wes' lasted 8K miles running 14 psi low boost and 22 psi high boost, maybe the 5 year old kid that tightens the comp nuts on the T70 was sick the day Wes' turbo came along the assembly line and a burly 8 year old kid cranked on it, huh?

Fuckya CDM powah.

Re: I've seen it all now.
 

sounds good on paper

Re: I've seen it all now.
 

No, it doesn't sound good on paper. It was a smartass remark and isn't how a compressor map is laid out. :-*

Re: I've seen it all now.
 

Hey, instead of that guy buying 3 ---- turbos (and hopefully not a 4th) why didn't he just buy one decent one? Can you just weld the bolts on before using? Ghetto as ---- but so are the turbos.

Re: I've seen it all now.
 

First was cheap, second was warrantied, third (when SSAC would not reply) was supposedly (I'm third party to this, dunno the details) a reman with good stuff inside of it but turns out it was a replacement CHRA.

The guy who owns the car works at Borg Warner, I have no clue why there isn't an S200 on the car.

Re: I've seen it all now.
 

Glad Steve's car is finally running (or not now i guess). Damn good numbers for the stock pump.

You guys dyno at WNC? "Three guys and a drum" LOL! ::)

Yeah I think I need to ride in that EG, kinda scared of steve's drivin though, after watchin that 0-to-PegDaSpeedo run on jasons dvd... :S

Harry's Microtech cable and software was tracked @ LAX yesterday, so hopefully we can slap it on this weekend and at least get a base tune on it.

Re: I've seen it all now.
 

LOL, no, the comp wheel is trashed and his car got my AAA home - "tune with me and tow for free" is my advertising slogan, you know. Car is as skittish under power as a 14 year old schoolgirl on PCP, at 130 you'd be scared on a vacant stretch of interstate.

Re: I've seen it all now.
 

Doesnt Wes have one of those super t70's laying around?
Slap that sum bitch on steve's car and go hunting this weekend, the ECX boys are planning a cruize sat night at sonic's, go show em what a fast car is. Zeky boi is probably gonna be their too, HINT HINT!!!

Re: I've seen it all now.
 

I think they plan on just that, it'd be funny because the car is alright at sub-70 mph speeds and Goforth can outdrive Zeke in it. ----, my daughter could outdrive Zeke in my beater.

Re: I've seen it all now.
 

Hell instead of threadlocker. Rub some JB on the threads and just wipe off any leftover so it wouldn't toss of the balance. Ehh?

Re: I've seen it all now.
 

I'm betting 15 in/lbs with a torque wrench fixes the problem. Turbo will trash itself in 5-10K due to balance issues... Wes' is supposedly balanced, but the shaft was warped and had to be fiddled until it was true so who knows how well it will hold up.

I don't recommend anybody gets a T70, ever. Wes' and Johnny's are the only two success stories out of seven T70's I've personally touched, and I know of another 5-7 from other people I know and trust not to exaggerate/lie/make noise, like Hitchhikkr's roomate & co.

Re: I've seen it all now.
 

So if I just take this thing to a diesel shop where they rebuild turbos just ask them to balance it and I should be good or just expect it to die soon after boosting?

Re: I've seen it all now.
 

It's SSAC, it'll fly all to ----. T70 is not a big shaft turbo, they aren't exactly robust.

Re: I've seen it all now.
 

Have you seen an ant eat it's own head ???





THEN YOU HAVEN"T SEEN EVERY THING

Re: I've seen it all now.
 

i want a 14 year old girl on pcp :(

Re: I've seen it all now.
 

ive seen a supra or 2 on eGay with those god awful T70 Master Power pos snails on it...

Re: I've seen it all now.
 

What is wrong with Master Power??

Re: I've seen it all now.
 

Nothing, he's just cornfuzed. :P

Re: I've seen it all now.
 

So was I. Masterpower is a reputable turbo manufacturer. Maybe you should think before you type a response?
