Toyota isn't listening to my requests

How hard to rewire the battery into the trunk?

Good info here, but tough to tell what's going on with the torque/hp graph photo. The numbers just don't seem to jive with one another that well.

Does it say the front seats have memory of last location...

So when u fold the front seats down it know where to go back to cause good I hope so.

From the "see-through" drawing, the driver's center of mass appears to be approximately halfway between the axles, so the weight will be added about equally to the two axles. So it's not like, say, and NC Miata that is a percent or two front-heavy empty but 50/50 with a medium-sized driver.

Adding passengers to the back row will certainly put more weight on there rear axle.

If you take a look at the other cars listed under the 460mm..(18.11)

LFA 445mm (17.5)
GTR 495mm (19.48)
360 447mm (17.59
STI 534mm (21.02)

Im pretty sure thats Center of height, which is loosely translated to CoG

CdA lists at 0.27 which is same as the 09 GT-R (.27)

There's no numerals for RPM on the graph, however torque and power peak appear to be much further than 400 RPM apart, more like 1400 RPM apart. Also, I'm not a fan of that torque curve; it's too much like an n/a 2ZZ or F20; it won't feel natural, linear, or flexible like the Miata engine.

i expected a much flatter torque curve. is this D-4S related perhaps? in the literature there is talk of the engine using a mix of DI and PI in low and mid rpm, and DI only in high rpm...

super easy,

get a kit from summit racing to make life easier

RRnold · 11-02-2011, 01:45 PM

More info!!! Keep it coming Hachi! :happy0180:

Talk about high compression!

So that is how they expect us to haul a set of 4 wheels, your gear and a full size jack. Gotta do what you gotta do and make it happen!

This car is definitely a home run inside and outside!

Never tried it before but love the idea of it. Moving weight is better.

Also noticed that transmission could be dirtictly linked to the gear seeing how Dar back it is looks perfectly inline

WingsofWar · 11-02-2011, 01:47 PM
