As I've found out, we're pushing the V3 way beyond it's efficiency. That's why I'll be upgrading to the V7.

Yeah lol I was reading that too, which could be part of why it was spilling oil for me. Not sure why others didn't have that issue but I do!

If my blower is repairable I will just find a way with my buddy to come up with an oil return system that way any spills / spouts / leaks coming from the top of the blower will be returned into the blower lol.

Or I can just do what others did and slap a shipping plug to replace the vented plug. Lol.

Or... just upgrade the blower but not knowing how to fit a bigger blower and what items I'll need to properly connect it to the current A2A kit.

Some sc's have the oil issue and some don't. Don't ask me why. That's why I had to go to the 3.00 sc pulley instead of the 2.85. I still get a little oil coming out even with the 3.00. Some guys have put the shipping plug in with no problems. I was thinking about installing a pressure gauge in the vent hole to see what kind of pressure build up there actually is. If it's really low then I'd just plug it and not worry about blowing seals.

The V7 bolts right up to the stillen mount. I believe you'll need a larger bpv but otherwise the a2a kit can be used.

Makes me think if i should have just used the shipping plug hahaha. Awh well. Ill find out when we open it on thurs / fri.

That will heavily determine which boost route ill go haha

It seems the set up for both the 2200x and the V7-YSi are extremely similar except the 2200x has a higher CFM while the V7-YSi has an advantage of only +1000 RPM max speed.

CFM is more important anyways.

The Discharge OD: 3.0" same
The Inlet OD: 4.0" same
The Inducer Diameter: 3.7" same

Discharge ID: ??? on the 2200x while the V7-YSi is 2.64

Also, it says I can't order the V7-YSi in California lol so I'd have to outsource it and have that person send it to me or something.

Not sure about the 2200x though if that would be able to be sold directly to me or not.

And max power is 1200+ HP for V7 YSi
While max power for 2200x is 1300+ HP

Also has option to come with oil feed & drain line kit while the V7 YSi does not as far as I can tell

None of that matters if the Paxton doesn't bolt directly to the existing bracket.

That's good, give's you another option.

[cupcakez]

Yeah I might go V7YSI If it ends up being easier that route but we would need a different Air filter correct? What all would we need to change to make it fit? Just a bigger BPV and i would assume a bigger intercooler, and bigger couplers only correct?

I'm running the turbo guard, I'd probably do the same with the V7. Or, fabricate a custom intake pipe with a filter.

K thanks. Ill figure it out.
If i find out the 2200x rly doesnt fit ill opt for V7YSi
If it does ill get 2200x

If blower is beyone reparable then ima go GTR TT system lol

So which is it, tt or paxton or V7?

Here, I ran some theories.
Here are my options.

GTR Twin Turbo Setup (Irreparable Blower)
[ ] +$2150 (Sell current a2a kit)
[ ] Trade a2a kit + bad blower + $100 for the full TT Setup
[ ] Pay $1400 to to install TT Setup
(Random estimate of ~40 hours labor)
[ ] Need to pay to take apart a2a kit and then pay for shipping of all parts
[ ] Install needs to be done either at friends house or if my house, then within 2 weeks max, preferrably 1 week of straight grinding, and make sure no oil spill mess and we are clean the entire time / organized, otherwise mom will kill me.

Total:
- $1500 OOP costs + Shipping of all parts?
- Low OOP cost
- Low risk build
- High power output
- Can be upgraded to hold 850whp
- Need to tune to limit TQ to 430ft lbs.
- Purchase High Quality Downpipes
(change address to PO Box in 95249)


V7-YSi / Novi 2200x (Repairable Blower)
[ ] ~$600 bearings replacement + labor
[ ] Sell blower ~$2500
[ ] Net gain: ~$1900
[ ] $1900 toward new blower, save up $2000 more for Paxton Novi 2200x
[ ] Potentially save ~$2200 by end of November to buy blower if work OT the entire month
[ ] Slap on Turbo Guard for air filter
[ ] Find bigger intercooler, piping, couplers, clamp sizes, new SC belt, pulley sizes & maybe make same Y pipe but bigger pipes to match blower size diff between v3 and v7?
[ ] Need to find buyer for blower
Total:
- $2200 high OOP costs
- Low Risk build
- High Powered Output
- Easily achieve 700whp with limiting TQ to 430 ft lbs. with tune
- Use same current a2a setup with bigger couplers and piping?


928 Fully Upgraded v3 Blower (Repair&Keep)
[ ] IF SHAFT NOT BENT.... ($600 - $1600)
Buy new bearing and impeller, have it rebuilt
[ ] Put shipping plug on both ends to prevent oil from spouting out
[ ] Risk of blowing out seals due to X amount of pressure being made in contained blower
[ ] Risk destroying blower again, wasting $1600 that coulda been spent toward a new blower
[ ] Come up with a custom oil return line fitting so spilled oil goes right back into the blower
[ ] Come up with a way to measure inside pressure made from blower when spinning super fast?
Total:
- Wide Range OOP costs pends what broke
- Medium Risk build
- Pushing limits of V3 blower power output
- Use same current a2a setup, no change


Ill need to wait til I get back from work this week to open the blower and see what is wrong with it.
That will be the determining factor of the direction I go as far as:
TT or SC route (Paxton or YSi)

Are you guys just guessing you need a bigger front mount and bypass valve? Is there anything to back this up?

The bosch valve that stillen provides for use up to 10psi of boost has a total area of entry/exit of 5.07cm squared. The Tial QRJ has an entry/exit of 11.4cm.

Intake temps have not been an issue for the guys running up to 700whp. I guess if your goals are much higher than that, you could look into it.

You guys think I can safely keep the same 720hp intercooler from the a2a kit I have if I upgrade to a V7 YSi / Novi 2200x?

Or I will need to change the size to a bigger intercooler rated one? And I am pretty sure I can keep the same custom Y intake pipe that came with the kit as well if I go up to a bigger blower correct?

Id just need to change the coupler sizes and possibly put a turbo guard on the new blower assuming I am unable to find a fitting air filter.

What do you guys think?

I think I will stay the SC route regardless of my current blower status , if its repairable ill repair it and sell it to someone who wants the 928 upgrade but doesnt want to wait all the time to send it in and have it rebuilt then sent back.

I been thinking about it and I dont think I want to swap to TT only because I love me an SC lol even though they can be stubborn!!!
