Which blower is best?

I know how that works.

Whipple, for sure! Only SC I’d go if I didn’t have twins.

Whipple for sure. All supporting mods with 11 psi puts down 747 rwhp.

I would say a 2650 PD blower is best. The 2.9 whipple will make good power but would be way down on torque compared to a PD blower.

The Whipple is a positive displacement blower. It has mountains of torque. Along with every other PD blower. Whipple is a torque beast

[tartagliazl1]

The Whipple is a screw charger requiring a male and female rotor to achieve the claimed internal compression. Due to this design the rotors must have a different number of lobes on each rotor - Whipple's design uses 5 lobes (on the female) and 3 lobes (on the male) Since the female rotor is the driven rotor, the male rotor must spin 5/3 times faster. The max RPM for the 2.9L is rated at 18000 RPM which means the male rotor is turning 30000RPM which is a pretty high bearing speeds for this unit.

The Eaton TVS 2300 is a high-helix roots supercharger meaning it utilizes a set of matched rotors (same # of lobes on each) and due to it’s design, it is not capable of internal compression (which minimizes pumping losses during cruise). It’s Eaton OEM rated speed is at the highest speed allowed for infinite bearing life (yes that means the bearing is expected to last forever) and a max temperature rise across the SC of ~130 degrees C (max outlet temp of 150C) which occurs at 18000 and 2.4 pressure ratio (21psi boost).
Not surprisingly the Whipple 2.9 uses the same bearings, so as you might guess there is quite a bit more flow in the Eaton TVS if we were to set its max speed to the same level as the 2.9L screw. Since both rotors spin the exact same speed in the TVS let’s increase that allowed bearing speed limit to 24000RPM. Now our 150C (302F) outlet temp still applies so we probably can’t run 21 PSI of boost continuously, but 18psi will probably be just fine for a V8 application.

At 18000 RPM a Whipple 2.9L blower is capable of moving 1720 CFM as per the Whipple website.
At 18000 RPM a TVS 2300 blower is capable of moving 1461 CFM.
At 22000 RPM a TVS 2300 blower is capable of moving 1770 CFM.
At 24000 RPM a TVS 2300 blower is capable of moving 1900 CFM.
So to match the 18000 RPM max output of a Whipple 2.9 you need to spin the TVS to about 21,500 – beyond that speed it will outflow the Whipple 2.9L.

Unless you go with the updated rotor package (2650) in the magnum series. That outflows the 2.9 and at cooler Temps. However whipple also has a 3.1 i beleive and magnuson just announced 3.4 version at sema.

I have a 2650 on order. The cooling and efficiency was enough for my plans (it can max at 12-1300 hp which I'll never get near).

[The_bald_eagle_machine]

Well... I did it. Unfortunately with the Whipple it just wasn't as much money as I wanted to spend. As soon as I considered buying the whipple, then injectors, then fuel pump, and whatever misc... I just couldn't do it.

I did however, order the Torqstorm blower with a 3.1 pulley, 850cc FIC injectors, and a ZL1 fuel pump. I will also be ordering an intercooler kit from Mr.Bling motorsports once I am able to gather some more funds. I am gonna go with his kit because that is what Torqstorm recommended and the kit is specifically designed for the torqstorm blower. I think that this setup will make all the power that I want personally. I can't afford to be slaying tires, and burning up clutches making BIG power. This is a Legit Street car after all.

Follow-up question... I am wondering if my TSP High flow cats can handle the boost? I will have to reach out to them and find out.

[cc-rider]

Congrats. Any boost is good boost and you’ll enjoy the hell out of that blower.

A warning on high flow cats…don’t do it. Go search my posts and read up on how my high flow cats let go, plugged in my x-pipe, and blew my engine.

*gulp* the problem with that is that I already have high flow cats on my car currently from TSP. The kit did include a set of offroad pipes as well. Maybe I will swap in the offroad pipes before i do the supercharger install if thats the case. I did send an email to TSP inquiring about the durability of the cats, I think they are also going to tell me to remove them.

Congrats, as with anything there is no 1 right solution, it's what works for you!

That is definitely I great start but just be prepared to not reach your desired goals. I didn't reach those numbers. That's why I'm waiting to get back in the shop...it's still a huge upgrade compared to what it was though.
Are you planning to do the install yourself? I didn't see labor and tune in there.
