JB weld instead of welding might have saved it from warping.

Warped it on the side that matters least. That's the intake area, low pressure. Seal really needs to happen around the outside, not a lot of grinding done there.

What in God's name 😂😂 that's ridiculous. Add a salad bowl and nitrous plate next

It's probably easier to build an adapter for the stock throttle body location.

These tests are just what I needed

You spinning it the wrong way with the ratchet making anti boost...

Yea it was a stupid idea!

Gota love this crazy stuff. I wonder if you could have found a peace of aluminum pipe and thread it in instead. But with fuel in the blower I am not so sure the distortion is that much of a problem.

I had no idea you were going to modify it to like a b&m mini blower or that the rotor pack would work that way .... I wish you were closer I could have run a boring head through the case to make it right after the welding .... Looking forward to the video on rear Mount carb which is how I figured you would do it ..... Crazy what you are getting out of this little supercharger

Dude your my hero!! I’ve dreamed of doing this a hundred times but never had the guts...thanks for proof of concept! Don’t know if I’ll ever get to try but thought of grabbing a $100 283 sbc.. I bet you could make 400+ for under $500. You. Should do a 1hp per dollar challenge... also I wonder if aluminum mig spot welding would put less heat into the case and help with the warpage... YOU DA MAN!!!😎👍😁

I never in a million years thought this would work

That overhead carb view during the run was awesome! Especially since you can hear what the carb is doing as well :o) Well done, Super Richie!

These test are awesome, I love how you basically are trying to find all the junkyard gold

This man has literally the funnest job on earth!

Awesome video! I currently have a Twin M90 setup on a Small block chevy i fabbed up a few years back. I took my blower housings to the band saw and cut them off right at the back of the bypass holes. I then welded the bypasses shut and fabbed up flanges on the rear of the blowers to connect an upper intake to. I fabricated my lower intake on top of an old performer intake, basically welded a box on top of the 4150 flange, then funneled it up to fit the base of both M90's. I did all of the lower intake welding first so i could bolt the blowers down to the base before welding on the rear of the housings. I also did my welding with the blowers assembled. I feel you might have not had nearly as much warpage if the front cover was in place at the time of welding. Or even make a dummy cover out of 1/4 inch steel to hold the large opening in place while putting the heat to it. I am running a serpentine pulley on the crank off of a TBI, chevy truck (not sure what diameter that pulley is) with stock pully's on the blowers and it makes about 11-12 PSI at 6800 to 7K. I was running a 750 Mechanical secondary double pumper with 78's in the front and 86's in the back, but with a power valve block off... Unfortunately my lack of knowledge on setting up the carb ended in me running face of the sun lean and i melted a really nice set of blower pistons out of it... Really should have boost referenced the power valve properly.... Right now it's back together with a stock bottom end, and if my math is correct, at least from the Blower Shops equation, I actually need to bump up to a 1050 to feed what the twins are making....... It's so cool to see this stuff tested on a dyno while making all of these wild changes, Keep it up!!

I have been watching you for year's and just love your work. Rock on bro. 😊

So we definitely know Richard drinks or partakes in the wacky tabacy to think of this 😂

I had my silencer ports welded closed and suffered a very very small amount of warping also. The M90 sounds easy 2x as good now.

Great test! Thanks for spending the time to put that together for us to enjoy.

I always wondered how that would work out, waaay outside of left field on that one and over the highway! Right were my thinking goes! So damn cool to actually see this!
