comptech supercharger performance
i know it's not out yet but what sort of performance gains can we expect? the only way i see justifying a supercharger purchase for me is if it will make the tsx just as fast if not faster than the slightly more expensive 6 cylinder vehicles, ex, g35 coupe, sedan, tl-s, new tl, altima se-r etc. camparing manual to manual or auto to auto. and that's also hopefully at the boost level comptech has decided to release it at 5-9psi? any feedback would be appreciated thx.

Wow so critical... First of all a supercharger is NOT that heavy. Second with the supercharger, i/h/e, better tires/wheels, and hondata we could EASILY be faster than the TL/Maxima and then some. Plus with the aftercooler thats even more horsepower gains...

G35C
3435 lbs / 280 hp = 12.26 lbs per hp
S/C TSX
3230 lbs / 270 hp = 11.96 lbs per hp
With nearly equal power, it'll be close but I think the edge would go to the TSX. From a stop it would be harder but from a roll I'm sure the TSX would be faster.

.. with hondata alone the tsx is putting out not even close to the power a SC'd tsx would put out.. and factor in aftercooler kit and possibly a k-pro tuned SC.. the tsx would definitely give those cars a run for their money.. and yes.. he's right you can't judge how fast a car accelerates by peak HP, as proven by the hondata reflash..plus the 270 hp is not really a sure thing and usually honda/acura underrates their HP..

Power to weight ratio is still a pretty good estimate of performance. When you're racing you're going to be within 15-20% of peak power all the time anyways.
Besides, predicting the performance of something that doesn't exist yet isn't exactly a scientific endeavor.
that thing is fast.

Anyway, few people (or no people) here bought their TSX for its balls-out power, most of us bought it for the handling. Having the handling of a TSX with the power of a TL would be much, much better than what many of those other cars listed above have to offer on the whole.

One of the only major flaws I see with the TSX in the lack of power, if you put in an s/c, then I think you have pretty close to a perfect car IMHO.

Roots Type Supercharging
The Roots Type Supercharger is the first style supercharger that was ever used and can be dated back to the 1880s when the Roots brothers designed it as an air conveyor for mine shafts. Roots blowers act like air pumps (not compressors), and In general, Roots blowers have a two or three lobe rotor design, depending on the size of the case. Roots blowers will give you positive pressure to your motor from just a crack of the throttle, and will give all that they have to offer at full throttle no matter what the rpm of the motor. Roots Type Superchargers may look awesome hanging out of the hood and are great for those looking for drastic power increases at lower RPMs. Roots blowers are also extremely reliable and require very little maintenance, which is why Ford, GM, Mercedes, Jaguar, and Austin Martin have all featured Roots blowers as original equipment on select high performance vehicles.
Recommended Usage:
Street Use - Towing - Extreme Drag Racing - Show Vehicles
Positive Points:
1) Boost throughout the entire RPM range, right off of idle
2) Highest Potential for Gain (A must-have for all-out drag racing)
3) Excellent Reliability
4) Great Appearance & Stature (Most common supercharger type for show vehicles)
Negative Points:
1) Sometimes Violent Throttle Response
2) Lower boost ratings at higher RPMs
3) Higher Than Normal Discharge Temperatures
4) Lengthy installation times

The Whipple is a screw-type pump, which is a positive-displacement design that shares many of the virtues of the Roots, to include a similar boost trend.
