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.
