Do forced induction applications care about single or dual plane?

I am running an RPM AIR gap intake right now on my N/A, but I have an edelbrock Vic. Jr. intake too. In the near furture I will be making a twin turbo setup for my car. Do forced induction applications care about single or dual plane?

 

it is generally better to run with single plane intake, on forced induction.
dual plane can cause uneven air distribution, or staggered jetting will be needed to make work correct. i would use a vic. jr.,over anything else
im using a super victor for my blo thru lsx, would nothing less on lsx from now on, way better than vic. jr.
see sig

 

what is the main difference from a Vic Jr. to a super victor?

My car makes almost 400 to the wheels right now as it is N/A, but I will be getting a new camaro when they go on sale, so I figure this one can go nuts with some turbos. I wanna shoot for the 700 HP ballpark with a couple turbos. The Vic. Jr seems pretty straight shot of an intake. Oh yeah, this is pretty much 100% street driven. Might do FI, not sure. Figured with the Vic. Jr. I could have injector bungs added and do an aftermarket FI setup. But anyways, I am rambling now. This is all about 2 years away since my motor now has less than 5000 miles on it and is forged/ set up for N20.

Thanks for any tip. I am slowly working though all the info on here about turbos.

 

no need for twins, a single mpt76 will support 800bhp or about 600rwhp
thru a auto trans. lots of ppl making over 800 hp with turbos and carbs.
i would go with efi vic and 90 degree elbow and 90mm ls tb if going efi.
easier to fabricate a crossover and a t4 single turbo manifold using stock manifolds and or shorties. t4 flange sufficient for up to 800bhp with 3" dp

 

single turbo is MUCH easier to do on these cars. Check out my twin turbo build thread i just made. It can shed some light on how to make manifolds for it.

 

I have a 4" cat back right now with dual 3" to single 4".

What I really wanna look into first is weather or not to do single or dual. Like you said there are singles out there that make enough. I know that. But I worry about the lag of the car. I would rather have less power and fast spool, then huge power that I never see.

Remember, this is going to be a street only car that never really sees anything above 5500 RPM. Cuz as the car is right now, after a few seconds I am already breaking the law pretty bad as it is. I would just like to make the acceleration even faster later on.

Know what I mean?

I thought daul small turbos would be a better bet

 

Its only if you size the turbo right. You can use a smaller turbine side (smaller a/r) to help spool a single. With a very healthy 383 a single T76 with the common .96 a/r will spool pretty quickly as long as the manifold isnt too restrictive.

twins can spool very quick too but if you size them too big they will have lag as well

 

right right...

I know twins could lag too if too big, but I think that since I will run two, I can have nice little ones. This way avoiding the lag as much as possible by running smaller turbos.

Since the flow at lower RPMs is where I will be using the car, I want the turbos to spool imedialty.

The way I drive I pretty much shift around 2500-3500 around town. Ripping on the highway on ramp or something around 4500. Then at the track I will rev it way up to max power, but that is so rare. Thats why I want these things to be the fastest spooling turbos around. So that I get to actually use them all the time. Not just when hammering down.

 

your 385 ci will have no problem a mpt70 or t76, u will see full psi before
4k rpm, if auto. and use diverter valve instead of blowoff valve. diverter valve really helps with manual cars. but even better with auto. since the throttle nevr snaps shut under acceleration on an auto. spool is pretty much instant.
gear your car with 3.23 and that 385, that turbo will scream. way before 5500rpm.

 

Thanks for the input.

My car has 4.11s in it now, with a T-56 and the 385. I will look into the diverter valve you talked about. I need to learn a lot more. But at least I have a bassis. I will never own or build an auto car, just too much fun ripping threw gears. Maybe since it is a stick it will be better to run twins...??? No idea. Like I said, I want these things to be spinning real soon.

Well I think with the little advice I have, I can at least begin to know what the hell is going on.

By the way OVERALL, is a big single setup generally going to cost less than 2 small duals?

I know there is a lot of factors, but just throwing a stupid question out there, lol

In the end, I guess I will not sell the Vic. Jr.

 

that will more than likely be the cheapest route. But depends on which turbos/turbo you get and what manifolds you make/use.
