I installed a wood stove in my first floor living room. The temp in this room easily gets in the mid-80's with even the smallest slow burn fire, while the rest of the house hovers around 75 on the first floor and 70 on the second.
Finally to the question..
I am installing a duct in the...
IMO much of the steering feel is system compliance. Focusing on rack bushings, tire sidewalls and response, control arm bushings, body/frame stiffness and weight distribution, not just boost and ratio will round out the package. Minimizing compliance goes a long way to helping steering, but must...
Steering system friction is important on the "driver side" of the system more than the "hydraulic side". The difference is the driver side is unboosted and the hydraulic side is boosted. Friction has a large affect on steering feel and returnability on the driver side. You can measure the...
Depending on the initial angle of the lower control arm for the rear, the roll center will rise or fall in roll. This can give a different roll feel to the entire vehicle. A falling rc can give an awkward feeling to the driver.
Interesting post, and quite a mouthfull!
"Inclining the roll axis also has effects on TLLTD. If it is inclined so that it goes up as it moves rearward, there will be a larger TLLTD to the rear suspension from the RCH contributions. This could probably be easily mitigated by tuning the Anti...
This is a topic for the engine forum, there is a wealth of discussion about manifolds there.
my $0.02:
1) Equal length runners are good for balanced cylinders. However, it does not gaurantee it. Flow balance and equal length runners must be developed.
2.) Half order pulses can be generated...
Work with your tire supplier to help you tune this condition. Does this sportier version get a new tire?
Can you change body mounting points? If you raise the rear roll center, it will speed the response of the rear and decrease the roll bar rate required. This could decrease the toe change.
It sounds like you are slowly but surely tracking down this problem. I would agree that any kinks or changes in a toe curve are a bad thing and you should minimize that first. I think that will help you out. Do you know the toe pattern w/o roll bar? Does it smooth the toe curve?
Don't limit...
In my mind, the major factor would be c.g location. The front engine placement typically results in front weight bias. This is a more stable condition b/c the heaviest loaded tires give up first. If they are in the front, you get understeer, if it's in the back you get oversteer.
When you have...
Plastic intakes are good for a 2-3% gain over an identical aluminum intake for two reasons. 1) They don't transfer as much heat to the intake charge. 2) The surface finish is much better than cast Al.
One way to improve the heat problem with al intakes is the thermal isolator gaskets available...
I think a diagram should prove there is no difference at the tires. The inputs dont change(cg*cornering acceleration) and the outputs dont change(tire reactions)It may change the motion of the chassis from pure roll to combination roll and bump. Because of the asymmetric roll axis.
I dont...
I think of horizontal roll center movement like an imaginary number. It's significance is questionable and is mainly used to calculate the vertical position. The vertical movement is the real concern and the one that shows up in all the loading equations. Once you get into roll/dive (turn-in?)...
If the speed of the rotating mass is proportional to vehicle speed, there would be constant acc & dec of the rotating mass which also puts a torque on the vehicle and requires significant power.
A turbo is an energy converter, it uses the heat and pressure from the exhaust to spin the the intake compressor wheel. Turbos are placed as close to the ports as possible to take advantage of the high temperature of the ex gas before it cools. The boost produced creates a lot more torque than...
Valves are used in the exhaust of motorcycles to change the phase of the exhaust pulses. (Im thinking CBR 900RR, you may be talking about 2 strokes) The valve switches between 1&4, 2&3 collection to 2&4, 1&3 combination to get the best exhaust pressure pulse combination for the rpm range. These...
Most likely the loss of low end torque is due to the reduction of velocity, not reduction of backpressure. This is a consequence of the larger headers.
