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.

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.

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!

[cupcakez]

...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!

The standard 8 rib belt wouldn’t work with the 3.47” jackshaft and 3” supercharger pulley? Thought that was kind of standard setup.

I didn't have to change my belt when I went with that combo. Did you get your bpv silencer?

When I tried this combination... we found fitment issues for it and needed spacers or something IIRC.

So we only used the 3.0" pulley and didn't use the 3.47 or maybe it was the other way around, can't remember.

If you change the jackshaft pulley on the sc side then you have to add a spacer to the sc pulley and idler pulley. The stock jackshaft pulley that Stillen used isn't a Vortech pulley and has a different offset.

^ That was the issue. xD Yup. Haha.

@Redondo.

If I wanted to use a 3.0" and 3.47" pulley combination, which pulley spacer kit would I need from the photo attached from 928motorsports?

And these kits would work for like a 2.85" as well or nah?

I ordered the kit which came with the spacer that had to be cut because I didn't know what what the offset difference was. I'm not sure what the thickness of my spacer ended up being, I never asked my installer.

Yes, they work with the 2.85 also, they are based on shaft diameter, not pulley size.

Gotcha.

I'll order the spacer then because I know I'll be needing it in the future for whatever blower I end up getting.

It's good to know that the kit is based on the shaft diameter and not the pulley size.

Since we both have the same brackets, then I should be in the same boat as you.

Thanks!

Yep, definitely in the same boat. 😁

Since I blew up my belt.

I purchased this belt:
K080220

as a replacement.

This belt will be good enough to fit 3.0" jackshaft SC, 3.47" pulleys?

What belt part number do you have to fit your current 3.0 and 3.47 setup? assuming i had spacers too

[cupcakez]

/keeping my blower going to repair it and use it then put two shipping plugs on it instead of one to keep the oil from spilling.

i have a sound clip straight from 928motorsports representative saying that vortech recommends this.
