Current mods:
60-1 (hi-fi) cover .63 ar exhaust
Pfab log manifold
Id1000
Aem ems v2

Currently making roughly 400hp

Shooting for 600hp with room to grow (injectors will be the limiting factor at this point)
This coming week I plan on ordering the ELT manifold from pfab
Also ordering the gtx3582r
Setting up the flex fuel in the aem ems.

My big question is to either go split t4 or to go tial vband
There is not very much information out on this topic

The vband inlet seems like my best choice
I'm getting tired of bolts backing out even with stage 8s I'm having problems
Also by going split t4 I would have to purchase another waste gate.
Vband just looks cool and frees up a lot of space

This is a street car 90% of the time, so I'm not looking for a dyno queen. I want a nice power range throughout the rpm range.

Is there any information out there about t3/t4 vs vband

Should I go with a .82ar or a 1.03ar vband
Or does the split t4 have the best qualities
Or should I go t3

All opinions and comments welcome

Thanks in advance

 

If you do the Tial v-band, go with the 0.82 a/r. The v-band setup will be much lighter than the twin scroll and should make a bit more peak power, but won't spool as fast. I agree that the ability to have 100% vband is really nice. I have also had quote a few problems with bolts backing out in the past.

Pang's divided T4 setup is awesome. If you do that, get a 1.06 a.r. I have this manifold with a Borg Warner S300SX FMW and Full Race's double thread pitch studs. So far, nothing has backed out, but that doesn't mean that it won't. Keep in mind this takes up a lot more space under the hood.

I don't think you can go wrong either way.

Thanks for your input. Really leaning toward the vband

always go divid twin scroll if you can. It will make just as much power up top with a much faster spoolup and better low and midrange power

 

If you're worried about things backing out, get nord lock washers. I actually think Full Race includes these in their kits.
