Exactly what I do not want... I want the low end power capabilities of the roots style. The M90 is just about as large as I can go.honestly, a shorter bodied supercharger would be too small for the displacement of your engine. A centri charger would be your best bet my friend.
I agree with the perpetual project.... I have had so many ideas for what I wanted to do to my car for awhile now and I am trying to settle on one idea and move forward. Basically I want something unique which this project would certainly classify as and I have always wanted that eaton supercharger whine...Definitely open minded towards all projects but why a roots-style that was used on a push-rod L67 from the 90's versus doing the Coyote swap or Procharger? My guess is to keep the price underneath the cost of a Procharger? I think hidden R&D costs might creep up on you there. Packaging and hood clearance might be a concern (for those who don't want an even taller hood). Turbo is another good option where you can emulate v8 torque but I can see why you don't want to go turbo as progress for that is still in the early stages for reliable DD. If money isn't an issue I would just use a Coyote with the F150 plenum (which looked like your original plan) if reliable torque is what you're looking for. Though if you are set on it and want to do something different do it up. Either way definitely find a goal and stick to it or you'll have a perpetual project (been there done that).:headbonk:
They do sound good, there's no denying that. I agree with you on the state of turbo-progress for the time being. Definitely too involved considering the similarities of the 3.5 and 3.7. While there are a couple of quick boosted 3.7s, I haven't been impressed with the performance in some of the videos I've seen them in considering the money and time spent. Supercharging seems to be the balance king for these engines so far. Well if you can make a kit that has ease of install like that video good on-ya. There is also the M62 which is the baby version of the M90 used on the Nissan VG33ER.I agree with the perpetual project....

The coyote swap was the direction I was going towards but after pricing out everything required (its the little parts that add up) it would have been about as expensive as the procharger system and I would have ended up with basically a stock coyote. The procharger system is great but I have just never liked centrifugal superchargers (how they sound, how the deliver boost, etc...)
Turbo options are still early in development and are very involved installs. Oil return lines is what killed that idea since I would have to pull the engine (or pretty damn close) in order to remove the oil pan to drill return line holes. A scavenge pump is not worth it either as a decent one that is not crazy loud is almost $400 and there would be no guarantee that it will continue to work for a long time.
The eaton superchargers are a tried and true method of boost and the GM M90 is by far the most abundant and cheap. I would prefer something like a roush M90 but those are very rare and will have to have extensive modifications in order to decrease its height. Twin screws would also be an option if they were not so expensive for not as much benefit as people might think. There is a benefit to using them yes but I do not think that benefit merits a 10 fold price increase.
If I can sort out the lower intake manifold I believe I will be moving forward with the project. Either way I am still getting the hood as I have always loved that hood! It is not much higher if at all then the stock hood if you take into account the ridges on the stock hood. What it does do is remove the internal bracing and raise the center up to the OEM ridge height which should create the space where I need it without raising the entire hood surface.
Really now, almost the same price as a prochager. I would have thought it would have been more expensive. I was thinking that my budget for prochager is about 8k-10k. If that is more or less enough I might just do that stock motor et al...The coyote swap was the direction I was going towards but after pricing out everything required (its the little parts that add up) it would have been about as expensive as the procharger system and I would have ended up with basically a stock coyote.

If you went with an F150 coyote and did the isntall yourself the price would be around the $4.5-5k mark. That is also not including any suspension mods and brakes that would likely be not required but useful. Another reason why I decided against this is that I actually test drove a GT and wasn't all that impressed.... It felt heavy on the nose and not that much more powerful than the 6 in everyday driving. Now when you stomp on it you certainly feel a difference but I want that low end power.Really now, almost the same price as a prochager. I would have thought it would have been more expensive.

BTW yes Whipple whine is better than prochager whine. But both sound good to me.
The procharger kit to me is just not worth it at almost $6k. At that price point I will just purchase a coyote and have more of an upgrade path.Your better off with a direct fit procharger kit. I made 360 rwtq and 454 rwhp. Thats more then you will get from an m90 and it will run 100 degrees cooler and be very reliable.
BTW this was the inspiration for the project!
I had this exact setup on my first V6 mustang. My 2005 Sliver Bomber! greatest car I ever owned. back then Polar Express was selling those kits in the 2500 range....then American Muscle came along and jacked the prices by over 1500. I don't care what people are saying about the M90. that thing was a blast to drive. if you could create a doable kit for cars I will be all on board to emulate. Even an even 100hp would be worth the go.
I bought my whole kit used for $2900The procharger kit to me is just not worth it at almost $6k. At that price point I will just purchase a coyote and have more of an upgrade path.
