more air= more power, its like some turbos put out out 8 psi which si equivalent 14b at 16 psi
in general just liek a headm better airflow, more air allowed through, thus creating mroe power, i think the biggest thing to worry about is space but it should fit
i think no one will ever know until its dyno tested with results
but yah

You would have to upgrade the HE to compensate for the heat when not under load, but most people that are building for power are already doing that.

something to keep in mind is that your not under boost most of the time with a eaton, and as a result the charger takes only 1/3 of 1 horsepower to turn with the whipple it really makes no difference wether your in boost or off boost its compressing ALL the time i wonder what kinda heat that generates hmm
i guess its down to what kind of efficiency your looking for and price 650 bucks for a brand new m90 is certainly tempting

LMFAO it take more hp from the engine to spin that M90! If you want a better swap look for the kenne bell 1.3 <discontinued> or 1.5 <discontinued> on ebay. Even easier, do a centi swap! Or find 20,000 rpm bearing and put it on the m62 and pulley it down. But find a way to cool AIT2!

The Whipple 1.6L is borderline too large for our application. It may also suffer from a little lag, but not as significant as the M90.
Whipple doesn't offer a smaller s/c and will not. I have spoke with them a few times about it.
Trust me I'm looking for an alternate solution to the blower swap.

this thread just made me more confused than ever, m90,whipple, turbo ..... so in the end where do we stand? exactly where we were before lol, which is confused on what can be done to this car and actually make it function properly. does anyone really know what would work or are we all guessing?

M90, don't waste the time, takes 50hp to run at the top end when it maxes out. Delta temps are not really lower and the cfm flow just isn't there.
The Kenne Bell 1.3 will work and would be a good idea. Hard to find though and believe me on that. There might be a few whipples out there that would work as well. It is all a matter of how extreme do you want to go.
Centrifugal superchargers are also an option. Roush makes pedals for drive by cable cars where we could get a LS1 or LT1 TB (3.5" vs our 3.0"), larger intake and then we would need a larger MAF sensor from an LS1.

i need to start looking into that smaller whipple then or the kenne bell (spelling) What kind of centrifugal blower can we use any one or what

Kenne Bell will not sell the 1.33L outside of their $$,000 kit.
Getting a higer speed bearing for the M62 would not help in the inefficiencies of the roots at high boost, not to mention it would create some unbelievably hot charge air temps.
The M90 at 8psi would perform worse than an M62 at 8 psi because it would have to spin slower allowing boost to bleed more, and it would require more power to turn the larger rotors.

I still see M90 swap as more pointless than porting the M62. It will just rob you of more power...
See post #34 of why it is pointless and also what I put on another thread:

Also, if you are thinking of a M90 swap, I'd suggest not to but thats just my opinion. The cfm isn't much different than the M62 when both are maxed out and the delta temps on the graphs on www.magnusonproducts.com doesn't show that it will have cooler air.
All in all, it would be a waste of time IMO. Try it if you want but just letting you know in case that's what you're thinking. Oh and BTW, the M90 shows it takes 50hp from the crank to turn the M90 when maxing out so you'll actually lose hp because the M62 only takes about 30 when maxing out.

heres 6 facts to keep in mind (i pulled this out of my ass)
1. A larger displacement supercharger obviously offers more HP potential.
2. It runs cooler because it spins slower.
3. Bearing speed friction and oil temperature are reduced.
4. Cooler air charge temperature.
5. Lower parasitic loss (less engine HP to spin).
6. Larger pulleys have more surface area for less belt slippage and wear.

Why don't you guys just actually upgrade your valvetrain system instead of putting the smallest pullies in the world? I bet you guys would gain more power from a nice flow benched ported cylinder head, upgraded valvetrain (springs, retainers etc), blower camshafts from Comp Cams w/a stock sized pulley than going to a 2.6" pulley on a stock valvetrain system.
That's my take on it atleast.
