let's talk custom roots blower swaps

then both of them would be hard to adapt. one would go up into the hood, the other would go into the firewall.

the mp112 has an inlet similar to what we have so it could be easily adapted.
 
TVS blower are pretty loud Bio, especially when you get up to the 1900 and 2300. Flake has some vids of his regal. I'll see if I can find one.
 
The new ZZP rods allow for a internal balance. The crank itself is balanced the stock rods are just really heavy.

The biggest thing you are all missing about blowers is pressure ratio tolerance... To make any sort of power you are going to have to see pressure ratios over 1.5... anything over .8 is pushing a roots blower way out of its effective range.

Intercooling a M90 is going to be a better situation than upgrading to a non intercooled huge blower for most people, unless you are talking about doing some E85 / tricky RPM stuff... even then it is uncharted waters on both the e85 and RPM side of the boat that may or may not show gains.

A compressor blower is going to be the best option for a 3800, you just have to intercool the tits off it, which is basically impossible in our application as we have a crummy lim design and no "real" option for a cowl hood that would make room for a 5 inch + thick intercooler. I have designed 1 whipple setup (not installed into a car yet) for a fiero, and I am thinking that the 5x7x5 inch core I have for it is enough... but I am not really holding out much hope for it. I would consider that intercooler effective for a E85 car but this whipple setup will be for a 93 octane car.

The main benifit to a compressor blower is the fact that the efficency is measurable over a .8 pressure ratio... considering the goal is a 1.5 pressure ratio a whipple will still hold onto at least a 65% efficency rating (unfortunatly this is before blower drive losses), which is right up there in terms of a medocre turbo setup in terms of efficency. While a turbo will still make more power per blower (and well a turbo is probalby 1/5 the cost without issue), the whipple DOES technically have a fighting chance of making almost 600whp (shooting for 575whp with the current build) on a set of stock heads and c16 fuel and a 1.75 pressure ratio.
 


austin, that TVS is quiet. its like a stock m90 whine. LAME.

OOHHHH right, vinnie had the MP112 build. my bad.

either way i am just looking for something with a little more 'flare' to put in the engine bay. i DO NOT want to intercool the car though, that is 100% for sure. ill have to figure out a way around it (namely the heads, boost bleedin' cam, and meth). what kinda blower can i slap on the car and still make a bunch of power without lighting the inside of the engine on fire is what im after.
 
Since you're made of money...built in intercooler...
