Jrsc twincharging manifold modification... need some educated opinions
Working on setuping up the twincharged setup to be bypassed at high rpms, as well as increasing the plenum volume and adding a secondary set of injectors for meth. Here is what i have come up with but not sure on placing the injectors before the a2w cores is a bad idea. Plenum I have is a Hayward secondary plenum that adds 1.7L and has a 90mm entrance. Other option I thought of is lengthen the runners a couple inches and add injectors there.

Or another option is to add 2 large injectors farther back into the charge pipe

Imo youd better look some spray patterns and go from there about meth injection.And liquids even in so light form like spray dont like turns.(ask the guys back inthe day using 5th injector) Id use 2 injectors inside the plenum facing the runners.

I plan to use 4, 1 for each runner. Just wondering how bad the laminova cores will effect the direction.

Just spitballing here, so sorry for my (uneducated) thought, but I almost wonder if you could mount them on the bottom or under the runners?
No idea if you'd actually have room there or if you'd have clearance issues, but it wouldn't affect the spray pattern or anything of that nature.

Is there a way for you to bypass the supercharger?
*edit*
My apologies, didn't see that was already stated in the original post. What turbocharger are you running on this setup?

Re: Jrsc twincharging manifold modification... need some educated opinions
We have a ton of m62 from mercedeses here in europe and i REALLY wanna add one on my td05 b16 BUT im keep finding that if the SC is after the throtle body
the SC fights for vaccum resulting in a bad MPG drop.
On the other hand if the sc is before the throttle body you need some strange valve wizardry to work well and a good amount of trial and error.
In my mind you can make the SC feed the turbo using a big blow off or a vaccum actuator placed after the SC before the turbo.
In the low-mid rpm that turbo is sleeping, you will have possitive pressure before the turbo because SC is creating boost and the turbo is still before the rpm it starts to produce boost.
Once the turbo is spooled/needs more air than the SC can provide vaccum will be created and the blow off/vaccum valve will open letting the turbo suck air
though it.
This way you will also be free from SC belt slipping/custom pulley/big *** belt needed because the SC will need more power to compress the copressed air.
Thats my thoughts
Im really waiting to see your project finished.
