Vortech goes BOOM! - rebuild, replace or upgrade?
Hi All,
As per title, see attached.
Lasted around 8 years with the car being on and off the road. This year only I have been spinning it to 57,800 RPM
It's a Vortech Sci trim with an SI impeller.
Wanted to get your thoughts on either the following next steps:
- Upgrade the head unit to a Ti Trim (I have a forged motor)
- Rebuild this head unit using 928 Motorsports premium rebuild kit or ask Vortech to do it.
Any one had any experience on either?
Let me know your thoughts. If I keep this blower, i need it to spin comfortably at 60K ish.
More power would be nice too!

How did you eat up the front of your Impeller like that?
Get a V2 Ti-Trim, but you will need proper Fuel Supply, Either a CJM Stage 2 with a Walbro 485 or a CJM Stage 3 with a Twin Pump. Don't try to cheap out on your fuel system, do it Right.....

Who installed the Si Impeller for your unit? Looks almost the same as the impeller I got from Superchargerrebuilds.com before having 928MS fix it. The impeller they replaced my original SCi impeller with was cast aluminum and was very heavy, poorly balanced and definitely lower quality then the patented 928 Impeller. It was definitely a lesson learned.
And I agree, Follow Oldman's advice.

"I originally had a V2 that was upgraded with a Si impeller. that one had bad bearings so they gave me a brand new V3 which supposedly had my original Si impeller swapped over.
The V3 was brand new and never rebuilt. It was just an impeller swap from the old V2 unit."

Guys - for all those that have the TI trim:
If I wanted to run 'low boost' initially using my 340 pump, what would be the best pulley size to start with? I heard from a dealer that pulleys for 6 rib go up to 4".
Any advice appreciated. Thanks

I was spinning a V2 Si unit around 58k but I tanked my impeller. (This was with a 928 impellar and Super Rebuild)
Honestly I'm shocked it crapped itself so I have mixed feelings on 928.
Rather getting the unit rebuilt a second time, I went ahead and got the Ti unit. (I'm also fully built with 264 cams, 2.87 pulley, and 11:1 compression)
I'm running the CJM Stage 3 FRS with the Twin Pumps. (Because screw the annoyance of modifying the basket and hoping it fits flush... wasted money on Dynosty to modify mine for it to not fit correctly)
Here's my old Si trim and the damage it went through.

i dont have the dimensions for the Ti Volute, but this is my 3.12 pulley with my YSi, as you can see the pulley has like 2mm of clearance from the blower, and the space i have left in between that is where the belt it, and it rubs enough ever soo slightly to taje mayerial off overtime. Anticipate using my pic as a base, meaning the biggest pulley you can use would most likely be a 3.12. You can try using spacers on the 4 bolts behind the blower that secures it to the mounting bracket, however you wont be lined up as well with the cog pulleys in the back along with the cog belt.

Vortech head office are saying that the cause of failure could have been my BOV not opening. I am thinking of replacing it to be sure on the new blower - can anyone recommend one?

Tial Q 50mm with -2 supercharger spring is what i run. You can shop around for a better price.
https://www.jegs.com/i/TiAL-Sport/768/002579/10002/-1
Synapse is also a good brand, and you cant go wrong with Vortech's inhouse Maxflow Bypass valve. Ultimately you will need to run a bov that can flow out alot of air since you are going up in blower size.

Depending on the boost, there's also the Vortech Maxflow Mondo BPV. Honestly it's cheaper to go the Tial Q route in case for some reason you switch to a turbo setup. (Then just spend a couple bucks for a different bov spring)

Wizard, what dimensions you need?
Agreed, honestly I love the sound and quality of the Tial Q 50mm (It's F***ing loud) and the fact they have their own dedicated supercharger spring (The -2 Blue mentioned, the color should be green iirc)

Im happy with the Tial 50mm, makes the car sound like a harrier jet just cruising or creeping thru a parking lot. I always get weird curious looks 😂.

Non-RevUp, or RevUp?
Makes a Huge Difference
Yea, OP needs a visual on how the Ti Volute dimension size is in comparison with the serpentine pulley on the mounting bracket. I know for me with the YSi, the lowest i can go is with the 3.12 above.

Wizird, the 3.12 will Absolutly fit with the Ti-Trim....... with a Non-Revup.
The Warranty from Vortech Sucks........They will also give and allowance toward a bigger blower, but it's very small, less than $1000, and then you pay retail for the New Blower. There are much better deals out the than going direct thru Vortech.

I actually meant the manufacturers warranty. I'm assuming that there's at least a 1 year warranty of defects with the blower by Vortech, regardless of who you buy it from new? (presuming it's an authorised dealer) Is that correct?

Hi Guys
For the BOV;
I heard that the Tial QR is a lot quieter then the Q as it's recirculating.
Do you guys have any thoughts on running this with the Ti Trim? And also which supercharger spring?
