Possibly in the wrong section but I will let it start here

Lets say you are going to modify your xB or xA

And you are allowed to do anything to the engine or drivetrain
But there is a huge stipulation.....your not allowed to make any power what so ever....just make it more reliable and run better.....but for an exception you are allowed to do modifications to put more power to the wheels.....but nothing that adds power to the actual engine (intakes, headers, exhaust turbos, superchargers)

Now this is only to engine and drivetrain only....not going into suspension or wheels


Discuss and ponder

 

replace every load bearing metal bit with aluminum berrylium, and every body panel with carbon fiber. This should drop the weight of the car by like 800 pounds or maybe more.

then coilovers, Id tear out the rear suspension and get some custom double wishbones for the rear.

aluminum berryilium is of course so costly that its not even allowed in F1 anymore.

 

wtf are you trying to say. i have no **** clue wth you just said.

 

i would put in a flux capacitor

 

I said not including suspension...and I only said drivetrain nothing about the body.....read better next time

 

 

How can you not make any power, but add more power to the wheels?!?!

Hows that for "if a tree falls in a forest and no one is there, will someone hear it"

Only way to add power without add touch the motor is make your car less heavy.

 

ok
aluminum berrylium for every single bit of the engine =)

 

After reading this thread--I think I lost a few brain cells.

 

What he is asking is "How can I get LESS power loss from the crankshaft to the wheels?"

Say my car gets 108bhp at the crank and 95whp at the wheels...is there anythying I can do to get more than 95whp at the wheels while still maintaining only 108bhp at the crank?

 

ohhhhhhh.. so, that's what he's trying to say.
dinkjs, write better next time.

 

You can put more power to the wheels without adding actual horsepower.....lightened flywheel and a better clutch....neither add horsepower


And I was only using the Scion's as an example

 

yeah that would help lots of power there.... or maybe that AOL turbo thing the guys from Orange County Choppers are always pitching on Tv that could be some real power gains there...... :D

 

There were key words in there "reliable" and "run better"

Here is my list to give a wonderful example

Upgraded Radiator and fans...lower the ambient tempature of the engine
Upgraded Spark plugs and wires for better spark
Upgraded head studs like ARP
Lighetned flywheel and clutch


These are just a few examples....again I used the Scions as an example

 

The ARP head studs will not make it more reliable, they only help if you stress the engine more than stock.

A lightend flywheel may or may not make it "run better" depending on YOUR definition of "run better". Even if it fits your definition the cost vs benefit is not good.....

BTW, the ignition is coil on plug so you can't upgrade wires....

Upgraded radiator/fans=more weight=less performance.....

Useable HP gains are in the drive train and light weight rotating/reciprocating masses like crank/rods/pistons/flywheel/ring&pinion gears/axles/hubs/brake disks/wheels/tires. Again-cost vs benefit=not good.... common on max effort race engines/drive trains but not on street cars. Few people want to go to SMALLER disk brakes anyway.

Or is this a trick question????
ken

 

I got u all beat on this one, remove the transmission gears and add gears with less teeth, so when I am at 75MPH my RPMs are NOT at 4000. Remember that I am a muffler shop and my Parent company is a transmission shop. Many gears there and many ideas already in the works.

No HP gain and the life of the motor is saved. Question answered- NEXT!!

 

me too

 

weeerd i think we would have been beter off if we smoked a fat bowl deeeng!

 

i don't know if i am reading the topic right but what about adding- redline waterwetter to the coolant, wrapping the header with that heat resistant tape, wrapping the intake with the same heat resistant sleave, all this will not make (MORE power) but will keep the engine and exaust cooler to run and PERFORM better,

Is this what you want to talk about ? or am I way off the mark? like i said i really counldn't understand what EXACTLY you guys were pondering!!

 

Yea you got it right on the nail good job man
