When doing a Jokerz Race Port or Kong X Port blower will you lose low end torque? I want to do a basic bolt on setup.

Mods I am planning to do:
- Ported Blower
- 103mm TB
- Headers
- 5" Intake
- Lower/Upper Pulley

As long as you over spin the blower by at least 7-8%, you wont have any low end torque loss with the X port.

no real need for any intake bigger than the the size of the t/b .

OP's list includes a 103mm throttle body. You will absolutely see gains using a 5 inch intake over ANY smaller intake with an X port blower and pulley.

what I meant was using a 5" with a 103 theres a bottleneck at the t/b. using a 4" will net the same gains

no it doesn't. Obviously we've tested it. But so have others mti, amp, rpm, HHP, etc. 5'' is worth it every time over a 4'' on a full bolt on setup.

100% disagree. The 5 inch gains over a 4 inch or any other non 5 inch EVERY time when you're talking about a max effort blower setup. The harder you spin the stock LT4 blower and port it, the bigger the gains are. This even applies to the aftermarket blowers. The key is spinning them faster than stock speed.

I've tuned many Z06's with your 5 inch intake and it absolutely makes a difference. Great product.

this isnt even close to a max effort build thats the reason for my post

The OP is asking about a ported blower, a 103mm TB and an upper and lower pulley. That is getting to max effort territory. For his setup, the 5 inch is the only way to go. If you're talking about a stock blower with stock pulley, then a 5 inch intake isn't worth it IMO. I think you're comment may just have been out of place for the topic of this thread, but I understand what you are trying to say.

What kind of power would this setup make on 93?

I am curious as well. It seems it might not be worth it unless you do meth. I do not want to do meth again as I had it on my built 6th gen.

without fueling upgrades of some type I think 650-700, depending on the dyno, is the limit

Is 93 going to be enough fueling? Not for upper and lower pulley but all that was listed and just a 15% lower? Where would you be at power wise?
