Topgunz - air to air upgrade

Pull it and send it for professional repair. Sorry man...

EVOHUNTER · 06-09-2016, 09:09 AM

I wondering how it will boost. if I could get through my tune on the 24th, with out it blowing up lol.. then I should be good to go.

Ill send it out after the tune and have it rebuilt.

Funny thing is last year, right before I put her away, I got a knock out of her, im pretty sure it was this hitting my impeller.

It boosted fine 3 weeks ago, tuned great beside my haltech sensor **** out.

im kinda stumped here..

I have a friggen impeller sitting beside me, SI trim impeller that I never got around to getting installed. problem is I cant find a single machineshop/ shop that will touch it with a ten foot pole. vortech was 4 weeks, I might just split this baby today, see if I can do this myself.

If this doesn't go good, ill buy a new head unit.. have this one rebuilt, sell it or maybe keep it?

How long would it take to get a complete replacement? I'd go the new unit just so I could meet the tune date, then send this one for rebuild and either sell it with all the rebuild paperwork or keep it as a backup.

I wouldn't run it. What happens if a chunk of that comes loose when you're tuning and the motor gets a lungful of metal shavings?

Not worth the risk IMO.

TBatt · 06-09-2016, 09:50 AM

Do NOT spin the SC up with that broken impeller. If it comes apart you will have much more problems.

Seriously, the impeller balance is critical and if reaches max operating rpm it could come apart. I would remove the drive belt NOW!

As Ghostvette said, if the tune date is this critical you would be better off with a new SC which you should be able to get very quick.

Good luck and sorry that this happened.

Also, did you find the part that broke and the missing piece of the impeller blade? you don't want those parts ingested by the engine!.

yeah I found the piece,

good news is.... the impeller is already changed. Super easy to do.

took my 15 minutes, the SCI trim was already marked for me so I lined up the marks and she went right in.

Now with the SCI trim my fuel wont hold up, but ill get sebz to set my limiter so I wont go lean and ill upgrade fuel this winter

TopgunZ · 06-09-2016, 02:27 PM

Isn't sci a step down? You will run rich not lean.

I screwed that up lol, theres an SI in there now.

How easy was it to swap out the impeller? I want to swap, but not willing to give up the car for another 3 weeks to send to Vortech...

Takes about 15 mins, remove volute, 5-6 allen key bolts,

tap off the volute with a rubber mallet, remove the screw on the impeller.

its slides right off.

Mine did not slide right off, we bent the hell out of it trying to get it off.

I was surprised to came off so easy!

I ended up reading a lot up on these V3's, a lot of the mustang guys are running this guys impeller. They are claiming there psi doubled down low, but lost a half to a full psi up top. which I don't care, I would love seeing more boost down lower.

He also offers 150 rebate if a before and after dyno sheet is provided.

Anyways I ordered it last night, 425 usd, 78$ for overnight shipping.

I ended up taking to him about this stuff for a hour, he does some great work, he even bores out your volutes, all kinds of stuff. this guy knows his way around Vortech, if we want more boost, this is the guy.

He said with the T trim volute, , machine scoll impeller (the impeller come right the edge of the intake volute) bearings, boring, 15 psi at 7000 rpm 56000 rpm.
1223$ for everything, not bad considering the 928 impeller is 528$

Let me know how that goes. I'm going to run the SCI for now, but I'll def swap it out myself if that's all there is to it.

TopgunZ · 06-10-2016, 11:12 AM

Interesting but i have some concerns.

They dont make a V3 in a T trim.

15psi on what motor, the 3.7l? You could get 20psi out of this unit if you put it on a 2.0L and you couldnt get 10 out of it on a 6.2L. Its all a matter of how much displacement and backpressure there is to equal what the engine CANT ingest.
