SINGLE PLANE MANIFOLD- WORTH USING!!!!!
has anybody tried using a single plane manifold like the weiand x-celerator
manifold and adapter plate for tbi and notice any power increases throughout the entire rpm without sacrificing any bottom end.
i was considering to use one on my stroker 383 because my existing manifold has been planed and is not fitting correctly on the heads. this is in a truck has all the aftermarket goodys. i can get this manifold cheap and don’t want to loose my pulling power. the engine presently has the performer intake c/w holley adapter and 2” 454tb. i had to double up on the intake gaskets to fit the manifold.
is it true the tbi on a single plane doesnt require the vaccum like a carb engine?
383 stroker, 64cc 23deg trickflow heads c/w edlebrock performer intake and adapter, cam is an extreme 4x4 comp. Cam. 12-235-2 grind ( .447/.462 lift, duration 210 218 lift @50, 111 lobe separation) . unit has hypr. Flattop floating pistons, eagle cast crank, 5.7eagle rods. 10.2:1 comp. Headers c/w 2.5” flowmaster exhaust. 16147060 pcm, $85def

It's true that TBI isn't dependant on vacuum as much as carb. TBI can make adjustments with a custom eprom if there is THAT much of a lack of vacuum. It might be hard to see it but TBI is just like TPI except TBI is a wetflow. I would go with single plane if you don't plan on ever going with a carb setup. The flexibility of EFI is great! Just be careful of cam lobe seperation and you're good to go.
I personally went with an RPM intake but I think it would have been smarter if I had gone with a single plane.
There are a few guys that use single plane and TBI (Pablo, maybe more) and they like it. Don't go with a victor jr. just get the torker 2 and be happy!

The x-style intakes are outdated technology and dont work well. There are much better single planes out there but for that motor if low end torque needs to be maximised I'd go with a dual plane or a long runner multi-point setup... TPI makes for a great truck intake.
