Geoff from full-race says the 6758 will be getting the V band inlet option in feb-march? Just got a email from Jon Guerra (Full-Race sales) saying there are no plans for this option.

My turbo stuff should be selling the weekend, Im trying to plan my EFR setup. I really wanted the V-band inlet for a simple clean install. But if its not going to be an option than its not worth waiting for.

Any one know anything more on this ?

My power goals are 93 pump gas 375-400 whp, Race gas tuned to what ever the limit is.
trying to decide on the 6758 or 7163, I guess if no v-band option will be available for the 6758 and i have to use a standard flange, maybe i should just do the 7163 twin scroll for same spool up with higher power levels, or less boost for the same power levels?

We're already had a car on a log manifold hit 400 on 93 with a 6758, thanks to soviet.

And if Geoff is saying feb-march I would expect them to actually ship in july or august.

not exactly a "log" but yeah

close enough.

It's not a log manifold at all. Not even close.

Its not a "flowy log". Not I need to check the build thread, I think theres a good picture of it when its back from crack repair.

its like an ETD shorty flipped down. definitely flows better than your typical fm log

Yeah, found the pictures, it actually has a collector. So not a log.

Yeah I think my motor with new cams and skunk2 ultra intake with a artech axial low mount will shoot past 400 with ease. So I honestly don't have a set power goal. What ever my limit is I guess. What are Carrillo super A's good for ? 500whp?

:facepalm: Just stop posting.

Sav , how do you think a twin scroll 7163 will compare to the single scroll 6758 ? How will the 7163 compare to a GT3071R as far as spool and response ?

I would expect the 7163 to spool better. It will definitely respond better. No idea how a TS 7163 would compare to a single-scroll 6758. My interest is in the large-A/R T25 IWG 7163, as it will bolt up to our manifold and should still make 500whp with good spool.

So being a total noob(maybe even knob) here, what rpm would one be looking at for full boost on a bp4w and utilizing a true twinscroll manifold for this 7163?

^ 3233 rpm

Its going to depend you your displacement and airflow capabilities of your cylinder head. I think i will be finding out at some point as i have a pocket full of cash and I'm just waiting for some emails from ARtech and Treadstone performance. More than likely i think I'm going to be going with a full twin scroll 7163 setup

I figured it would be a tough question to get an answer for. I would be happy if full spool before 5k. Yah, im saving my pennies now.

Talked to Jon at full-race today. Both turbos that I want are expected in March. So I'm on the waiting list for

7163 twin scroll internal gate
6758 V band inlet internal gate

I'll probably go with what ever one is available 1st as I will be happy with either. Maybe I will bias one over the other when more testing is available.

GTR?

Yes. Full Race posted the pic.

They regularly post pics of EFR's being installed on anything and everything.
