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

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

I'll be changing mine out for the V7 Ysi, the V3 just does not run efficiently at the rpm we're spinning it at.

[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!!!

[cupcakez]

I did some research.

I can safely keep the same IC that came with the kit 720hp.

I can keep the same Y intake charge pipe that came with the kit.

I can keep same couplers on the Y intake pipe side of the IC.

I will need to get my own custom fittings for the oil drain line kit to make it work with the Novi 2200x, same as when setting up turbos just this is with an oil fed SC.

I will need to increase coupler sizes and clamps on the SC side of the IC.

And the Novi 2200x also does directly fit onto the same bracket as the one that came with the stillen SC kit.

Im going to save up and buy a 2200x blower.

Im not closing this thread, since im staying SC and still want to achieve my 700whp goal!!

Yay!

I never mentioned changing out the intercooler, I plan on using the one that came with your kit. I did mention changing out the bpv but the was based on what Vortech has in their description section regarding the V7 Ysi:

Large blower" performance in a smaller package that fits most existing Vortech bracketry. The V-7 Series combines the advanced technology and race-proven performance and fits most of our existing mounting bracketry. The V-7 is designed for vehicles with highly modified engines and extreme CFM/boost demands. All units feature our exclusive D-port volute for improved efficiency and require the use of a Vortech Racing Bypass Valve or larger to meet discharge flow demands. The heavy duty (H/D) configuration includes high speed, ceramic hybrid ball bearings, ideal for race applications, and is compatible with cog pulley/Gilmer style drive setups.

If the QRJ will meet the discharge flow demands of the V7 then I'd rather not spend the extra $300.00 for the Vortech Racing bpv.

I'm not looking to make more hp, your kit is netting me 656 right now, I'm happy as hell with that. You should be pretty damn proud of yourself for developing a kit that is capable of that kind of power.

The reason I want to switch to the V7 is I'm pushing the V3 beyond it's efficiency. It just doesn't run efficient at 62000rpm. I can go to the V7 and add the 3.47/2.85 pulley combo back in. That will spin it faster, bring in the torque at a lower rpm and with my wastegate and ebc, I can dump excess boost to keep it at a safe level. And I don't have to worry about oil blowing all over my engine compartment. It just seems to make sense for my goals.

...or should i keep it simple and rebuild my blower

If its rebuildable id like to rebuild it since the upgraded blower cost a lot lol

If not then maybe i just stick with novi 2200x

Ill have a more definitive solid answer by friday...lol

Just talking and throwing random options and ideas for now til i find out whats inside the blower lol

[cupcakez]

I called ECS and they confirmed for me that the 2200x is a direct fitment onto our vortech brackets from the stillen kit as it has the same bolt pattern.

Each paxton head unit has a vortech head unit counterpart. The 1200 is similar as our V3s
The 2200 is similar to the V7s, etc

The 2200x has a billet casing and billet impeller whereas the V7 YSi B is a cast casing with billet impeller.

If you ask me, I think the billet casing and impeller sounds more enticing.

So I am definitely going to get a 2200x and it will take 2 - 3 months to save up for it but it will be well worth it I think!
