many moons ago (1990) a blue and silver two tone mustang gt 5.0 convertible
caught my eye my then girly freind at the time had just had a head on hwy speed collision with a pettybone's solid wheel tire combo in her z31(1985 300zx)

it was 4:00am and she never saw it comming about totaled the rice grinder
it was then I'd decided she need something american

in front of the then wilson ford on the front row was this fine looking

blue/silver GT 5.0 5speed we took it for a spin and when we got back to the lot
we both focused on a Red Thunderbird SC

window sticker stated that it had a getrag transmission! took that toad for a spin and was wow'd by the screaming chicken's 210 horsepower it had a nifty boost/vac gauge and big goodyear tires..............................

ps we'll get to the blower question in a little bit (not a lot but a little bit)

 

Cool story b....


Actually curious to hear the rest LOL.

In for other post

 

speaking of chicken I'm putting the finishing touches on a Box el pollo loco

OK back to the blower girls, the top of the blower was plumbed to an air/air intercooler
I don't remember what the intake air meetering device consisted of seems the throttle body was as I know it rear inlet yada yada my question has to do with the top inlet and the air to air intercooler anyone familiar with this set up or own one of these V6 pigs

I kinda want one with a Chevy motor and a magnadoodle ................ red of course
note top inlet/intercooler palcement

 

Is anyone else concerned that bowtie guy was snooping around the ford dealer??

 

yea but I was so much younger then, I'm older then that now

ps I was 31 in 1990

back on topic s/c inlet with air to air intercooler somebody school me is that a 3way clusterfuck











later I aquired what would become my favorite car
a Black 1990 silverado sport it was a 454ss less the red interior, well that, and the 454

I miss that truck I miss it a lot

 

It looks to me like the plumbing on the passenger side brings air to the blower inlet through a MAF and a throttle, the compressed air comes out of the top of the blower and goes to the front-mounted intercooler, and the cooled air comes from the front in the third pipe (which must be mostly underneath the blower discharge pipe) into the engine, all of the way behind and underneath the blower. And it looks like a bypass from the blower inlet to the third pipe.

It looks to be much like my side mount, except upside down and not on the side.

I have never seen it before, so this is all opinion.

 

ok so the innie is really an outtie, and that really is a 3way clusterfuck/bypass
Good eye

 

Its a simple setup just like any other roots, just it uses a classic ATA FMIC instead of a sandwiched ATW heat exchanger. To do this, they flipped the blower and ran tubing instead of sealing the outlet port to the manifold directly. Clever take on the old idea, and it worked wonders. They ran more boost with lower IATs than an other roots blower for the time period

The funny business near the TB and blower inlet is for the bypass valve, so when you're cruising at low throttle, the blower is completely bypassed and the engine runs NA for fuel economy. Traditional setups use a butterfly valve connecting the inlet to the pressurized manifold

The M90's work pretty good on smaller LSx engines too, just dont expect huge numbers. Picked up 60hp on a totally stock 5.3 with the stock pulley


Need more of them for larger displacement engines like this 350 SBC


Once you grasp the remote roots concept, any roots can be mounted elsewhere. Here is MUCH more potent overspun M122 on a 6.0


Pros are incredibly good IATs even when spun to the moon. The pictured M122 peaks at 19,500rpms and the IAT is 10-15* over ambient. Since the head unit is remote, it can be mounted anywhere in the engine bay, so tight chassis can keep the low hoodline

Cons are an increase in complexity and they're incredibly loud compared to a traditional setup

 

Seems like same idea I had but didn't think the m90 could push enough volume of air apparently it can for low boost
