I’m pretty happy with my Hellcat. I’ve owned old Mopar V8 muscle, 80’s turbos, along with some european and brand X cars.
None compare to the Hellcat.

Ok, steering this thread back on track a bit. Finished up the model for the throttle arm modifications I have to do for the 76mm TB I bought for my BMF intake. Might machine it up this week if I get some time. Still need to figure out the end and bends to get to where I want the throttle to sit in the engine bay. But that's pretty easy.
That's a big boy TB. I've been modifying a Jeep 60mm for my lengel.
I think I came up with a way to eliminate the elbow on the intake
I have a Lengal plenum and want to add a larger aftermarket throttle body
instead of the TB mounting that the plenium came with I want to cut it off and add a sphere like shadow did to both ends of the BMF he was putting together but I only want to add the sphere at the TB end
then simply weld the base mounting for the TB at any angle I want , no precision angled or cut elbow needed just weld it on at approximately a 45* angle as I want to mount an intercooler over the trans & battery tray area so I don't need a 90* off the intake as the intake tract isn't going to run right past the end of the head anymore but rather over towards the old battery location
How much is the dome? You can get an aluminum 90 in 2.5 or 3" for under $20. You can get 45's but they are a couple bucks more.
IF I remember correctly I think the price is in the same range
I was about to ask shadow about it as I thought I'd found a boomba 70mm neon TB locally on the cheep but I haven't heard back from the seller yet so that fire died some
The 5” hemispheres were quite affordable from a manufacturer called “fat daddio’s” at Amazon.
Shadow and I both had this idea. I believe we discussed it in the BMF R&D thread waaaay back when.
I still haven’t even started my engine, but work continues! Not as quickly as I would like, but continuing nonetheless. 👍🏻

This cake pan? I'd be worried about thickness. It's only 16 gauge.

Pressurized the intake to line pressure of 125psi; no issues 🤷🏼-♂️

Would it be strong enough to mount a throttle body to it though?
Gonna have to turn the air somewhere. The problem I see with moving the mounting point on the Hemispherical is that you run into the possibility of starving one side of the intake vs the other for air. Maybe I'm wrong but if 2 molecules enter at the same point but one has to travel further to get to the same spot you know how it goes.
Example pics on BMF size Hemi with 3" opening. . No I'm not gonna take the time to get Solidworks to do a flow analysis.
well, you have a long and short distance example just looking at the inner/outer radius of the elbow
plus the limited elbow inside diameter right at the end of the plenum beside the runner to cylinder #4
the sphere would allow plenum "volume" to begin right at the throttle body - over past #4 maybe giving #4 a better chance to catch a breath
also the angled inlet would in part direct flow at the rear inner side of the sphere
this in turn might also help #4 as part of the air mass should stall as it hits the rear inner surface
though my reason for the thought was mainly about "packaging" the parts combo I'm considering in my limited L body engine compartment
I found another accel two stage foam panel style air filters to fit a 2.2
these filters have almost zero restriction when you blow through them and in an L body you can even feel a slight difference in throttle responce on a stock motor
planing a flat charger hood with a small mopar "pro stock" style scoop
I can build a simple air box under the hood to feed a log motor style air box from the top , mounted in the stock log motor filter position
a simple tube can connect from the back bottom corner to the turbo inlet
the compressor outlet can pass under the filter as it does on a TII
I can fit a much larger a2w intercooler in the area in front of the master cylinder & strut tower than beside the head like many seen here already - IF I relocate the battery
if the sphere is welded to the plenum and I mock up the build I can find the perfect mounting angle for the TB base easily without guessing or presuming about fit
and if I had the hole in the TB base plate cut to match the radius of the sphere I can save the thickness of the plate from the overall assembly length
as for the manifold support bracket like the TII ones - I think I remember reading that had more to do with making the knock sensor accurate than supporting the neck ( & rear weight) of the intake
I made a heat shield.
Won’t this shield trap the heat around the intake runners?
It’ll help keep the fuel rail cooler, but at the cost of heating the air in the runners, no?
Don’t get me wrong, I like it, and I intend to build a shield between the intake runners and my header myself.
Good to see others attempting things like this. 👍🏻
