#228 of 317 TC Supercharger by alliej Jul 25, 2006 (2:39 pm)
Can anyone give me an idea about the mileage difference after installing the factory supercharger? Replies to this message: Mr_Shiftright (Jul 25, 2006 3:57 pm) aatherton (Jul 27, 2006 9:21 am)

Replying to: alliej (Jul 25, 2006 2:39 pm) I'd guess 10% less...it depends how much you put your foot in it. At high altitude, the mileage may not change at all.

Replying to: alliej (Jul 25, 2006 2:39 pm) The purpose of the supercharger is to force more air into the engine so a corresponding amount of additional fuel can be used, for the purpose of making more power.   If it is possible to avoid using the supercharger, there is no change in mpg. Occasional or light use of the supercharger will cause a 10% reduction in mpg. Frequent or hard use of the supercharger will drop the mpg well below 20.
#231 of 317 Rattlying noise by curious54 Jul 29, 2006 (11:26 am)
Have a 2006 Tc 5-speed manual with CAI and Header. Yesterday I was in traffic and it was stop and go. I put it in 1st gear and went about 20 feet and let go of the gas and suddenly heard a rattle. Tried it in 2nd gear and it rattled but not that loud. The thing is that when it starts to rattle and i push the clutch the rattle goes away. Anyone know what might this be.

Replying to: curious54 (Jul 29, 2006 11:26 am) The motor rocks back and forth on its rubber mounts when accelerating and decelerating. The motion is most severe in 1st gear because it has the most torque, and lessens with each higher gear.    It is likely that there is not enough clearance around either the header or the CAI that you installed, and the movement of the motor is causing one to contact the the body.   If the motor rocks forward on deceleration, the CAI could be contacting the battery or grille etc. If the motor moves rearward on deceleration, then the header could be contacting the firewall ect. The first case is more likely. When you push in the clutch, you disconnect the engine from the transmission, so there is no torque to rock the engine over, which is why the rattle stops.
#233 of 317 Modifying 06' Tc Driver's Seat (Farther back) by mss Aug 10, 2006 (11:17 am)
Does anyone out there know if it's possible to change the mounting of the front driver's seat back about one inch without too much of a hassle? Love the entire car but if I could get an extra inch on leg room, I'd be a happy camper.   Thanks!

Replying to: mss (Aug 10, 2006 11:17 am) I've been checking seat mounts on the xA and xB and it doesn't look very easy. I presume the Tc has a similar system.   The problem is re-positioning the brackets that connect to the welded supports in the floor. Once you shift the track back, nothing lines up with the floor anymore, and the track and the mounts are one piece thingies.   I think this would require removing carpets, welding supports into the floor (after all, it is your LIFE we are talking about here) and re-fabricating the seat brackets.   Certainly do-able but it doesn't look easy, at least not on the xA and xB. I had the same idea as you but I am now discouraged unless I come up with a brilliant idea.

Replying to: mss (Aug 10, 2006 11:17 am) On the xB, a popular mod for tall people is to raise the front of the seat 1/2 inch. Maybe it works for the tC.   This is done with 8 fender washers on each bolt, and a bolt that is 1/2 inch longer. Remove one of the front bolts from the passenger seat. Take it to a hardware store that has a wall of bolt and nut drawers. Find a nut that fits the bolt, for reference (it will be metric fine thread). Use that nut to find two new bolts that are 1/2 inch longer. Find 8 fender washers with 1/4 inch hole for each bolt. Go back to the car, replace the borrowed bolt. Remove the front bolts on the driver seat. Loosen the rear bolts on the drivers seat. Center up 8 fender washers under the outside of the drivers seat, and insert the long bolt down through them and get it started in the threads. Do the same for the inside bolt. It may take wiggling of the seat to get the bolt aligned to start the threads. Tighten everything up.   Apparently just raisng the front of the seat 1/2 inch adds that distance to the floor and pedals, and helps alot in long distance driving. I am 6'-2" and just did it to my xB. I have not taken a trip, but just around town it feels better.

Replying to: iluvmysephia1 (Aug 10, 2006 8:11 pm) I dunno...sounds like an okay idea to me. There's plenty of headroom in an xB, and it has a tilt wheel to give you knee room if you lift the seat an inch...so this might work. Raising the seat is a piece of cake compared to trying to move it back anymore. You could always just sit on a 1" piece of foam and see how it all works before you do anything.
