And as for the new civic si against an sc tC, there is to much of a difference in torque I think to make the lightness pay-off while from a slow start. If they're around 40 mph or so, then it should be a close one!

If you have say a 15% drivetrain loss, you would figure your crank hp like this
192whp divide by .85 = 225.8hp at the crank
By multiplying your just adding 15% to the whp number and not actually taking 15% from the unknown (crank hp)

Verdict: s/c tC > new civic si
And for all of those that care, this thing pulls like hell on the top end!

Estimating that the supercharger and the other stuff it comes with weighs about 50 pounds or so (might be less might be more-anybody know?) the tC would weigh in at 2957 pounds, while the Civic Si will weigh in at around 2701 (the 2 liter engine likely won't weigh much more than the 1.8L version of the engine-even if it's more it's not even going to be close to how much a supercharger kit weighs).
At any rate, each horsepower in a supercharged tC would be carrying 13.75 pounds of weight, while the Civic Si would carry 13.71 pounds of weight (assuming it weighs the same as the EX-it might be end up weighing more OR less depending on the equipment and the engine weight). Either way they're neck to neck horsepower wise.
I'm too tired (it's 5AM after all) to run the numbers on the torque but I suspect the tC would have a pretty good advantage even after accounting for it's extra weight.
But the Civic would have the advantage of being a lighter-and thus more nimble-car.
Plus you could always just boost the Si and the whole argument begins again.
I love the tC but as a former Si owner myself I love the Si too ;) so don't be hating lol.
Heres he specs on the 06' Civic Si
2006 Honda Civic Si
Estimated Base Price: $19,995
Engine Size and Type: 2.0-liter inline four with variable valve timing
Engine Horsepower: 197 at 7,800 rpm
Engine Torque: 139 lb.-ft. at 6,200 rpm
Transmission: Six-speed manual with LSD
Curb weight, lbs.: 2,877
Estimated EPA Fuel Economy (city/highway): 22/31 mpg
Length: 174.8 inches
Width: 68.9 inches
Wheelbase: 104.3 inches
Height: 53.5 inches
Leg room (front/rear): 42.6/30.3 inches
Head room (front/rear): 37.8/34.7 inches
Max. Seating Capacity: Five
Max. Cargo Volume: 11.5 cubic feet
2,957-2,877= 80lbs
The tC will only weighs about 80 lbs more than the new Si with the S/C. The TC is a much more powerful and has more potential than the civic si. The only advantage is the LSD and 6 Speed. Overtime, im pretty sure TRD will develop an LSD for the tC since the tC is a direct competitor to the civic si. But right now, The new tC will dominate the new Si. No contest. The S/C tC has more HP, more Torque and is only 80lbs heavier. The 80lbs lighter the Si is, it's not gonna make up for 44lbs of torque the tC has. Therefore Scion tC> Civic Si.

basic math was one of those things that you forget as you do more stuff....I forgot to divide long hand and felt like a dumbass

rumor is that if you want to finance the s/c, you can only finance it if oyu finance from someone besides Toyota. just have the dealer add the s/c in the price and the other banks will finance. i am currently financed through toyota but when i finance i will be looking for another bank so that i can refinance with the s/c

Being the 2nd to have it installed, take it from me. It was finally nice and sunny today. Dry roads. Took the s/c tC for a ride. It sure pulls in the upper rpms. Not so much on the low end. But it feels good. Throttle response seems to have improved. I'm still breaking her in, so we'll see as she gets more miles under her belt

it's more than a 40hp gain..it's 192 at the wheels, not at the flywheel. and I don't see why some of you keep saying take off the parasitic loss from the supercharger to figure out the flywheel gain..that's like saying take off the parasitic loss from the accessories and crank pulley..it's an engine component, you don't really discount it like that. the way it compresses air/forces it into the engine is by the engine spinning the pulley. if it weren't spinning the pulley, you wouldn't be making the power.
