- Mugen stickers (the surface of these stickers is actually smoother than paint, thus reducing resistance in as many places as you can possibly find to put these on... the main goal, hypothetically, is to have a car made out of one big Mugen sticker)

- Aluminum gas tank doors (steel doors often are heavy, causing the car to pull to the left, or right, thus resulting in overcompensation of steering, causing weaving, which slows you down and also reduces gas mileage... for those of you can't infer the implications of this let me spell it out for you: You will have less money for the next deck you add to your spoiler, thus reducing downforce to keep the rear end down on a front wheel drive car.... it's a vicious, but proven, cycle)

- Hyperwhite bulbs (xenon charged bulbs are lighter b/c the xenon gas is lighter than the air inside of halogen bulbs... since there are 4 bulbs typically used for headlights in the front of the car, replacing all 4 with hyperwhite bulbs will drastically reduce weight, thus allowing you to lift the front end much easier on launches)


...I could go on, but I don't want to bore you all with these minor race-winning tips that you redneck fools will never realize

how aboout plexy glass instead of the real stuff. much lighter and safer in a crash!

then there is carbon or GRP body panles, again much lighter.

i have seen race teams drill steel doors (they had to use them) to help reduce weight!

i also read about a BMW M3 that saved about 60kg from the engine bay alone!!!!! plus you can normaly junk about 100kg front the interior!

ArticZ28, why even have head lights?!?!?!?!?!?! get rid of them and duct the cold air to the intake! lighter thanlights and will give you a bit more power!

then there is using a flat undertry to smooth the air flow under the car (can give BIG gains!!!). oh and raising the rear of the bonnet by an inch or so will reduce the air going under the car helping with downforce (well its negative on production cars!) and relaving some of the presure after the rad!

wings are bad!!!!! they are often crude and nit very efficent! thjats why F1 enginers try and use under body airo as much as poss!

Wheels area also a good area! big is not always better. mag alloy is also lighter than alloy wheels.

and the weight reduction list goes on!!!

Chris.

PS sorry for going off topic!

I put Millitec on all my motors,it reduces friction,how do i know??Because mpg has increased on every motor i have put it on.

Headers Pipe diameter is critical as the Collector size for geting the max flow at the cams peak HP/TQ.Matching the boltons to the rpm

Airodynamics,like covering underneath the rear bumper for less wind resistance(it´s like a paraschute)

Rolling resistace on the tires,but lower rolling resistance is harder rubber witch means less traction

How does it get around uneven firing?

Most people **** when they see how much money a well done block costs. I've had motors where the head porting labor and the block work and crank labor are the same amount.
What has been confusing to me is all the LS1 long blocks that are offered for not much more than the cost of the parts. How do they cover all of the measuring and machining?

Got me.... that's why I don't want to get into the price is right short block game. Costs more to do that in the end than just build motors the right way.

OldSStroker could really get into the header thing more... he's been on a kick lately.

its not funny because i dont think they do it for the reasons race teams do! i think they do it more for looks than to improve handling!

but before you all laugh at the wings Subaru and Mitsubishi use think about the thought thats gone into them! Subaru designed the rear wing on one of their cars to provide down force (well reduce lift, down force and road driving is a dangerous mix) when the are was at an angle of 30degrees i think!!!!! it was for the Group N rally guys, but shows you how much thought is put into the import cars!!!

there is also lots of air resistance around lights and bonet lines! this is why you see racers running carpet tape all over their cars! also some teams over the radiator inlet for the same reason!

thanks Chris.

by adding/taking away restrictions to have the gases move at a similar velocity through the primaries... i think, i could be way off i would think it would serve a purpose similar to an h/x pipe

I just like the tail wings .Minus the fact of how incredidly gay the car looks with it m if they got any bigger and a little bit more hp**cough** They could probaby take off . Which brings me to my next point ; why try to and downforce to the rear end of a front wheel drive car

I was not talking about wings,wings are there for a reason to increace the downforce to keep load on the tires but BODY KITS increase the front of the car that increases wind resistance and one some kits the panel that goes on the rear bumper is like a parachute

Much of the weight is on the front of the car so the load on the rear tires decreases as the speed increaces the car lifts because the air that goes underneath the car is heavyer than the air thar goes over the car and when Breaking the rear is much lighter and can cause the rear to sving out of turnes because the traction is much less on the rear tires because the load is mostly on the front tires.The downforce is needed at high speeds 80mph++

Look at the fiering order of the V8 witch has 2 banks compared to a 4cyll with only one bank

The firing order in v8 is 1-8-4-3-6-5-7-2 5 and 7 are on the same bank

Personally I always thought Hondas would perform best if launched off the deck of an aircraft carrier.
Maybe we've just been ignorant of the practical use for park-bench sized wings on the back of compacts. If the incidences of motoring accidents in Japan show a significant trend of the involved autos taking flight at some point, then perhaps the wings were added with improved safety in mind. A skilled driver may be able to glide safely to an empty field.
Makes you wonder what will be the next trend... perhaps rear mounted parachutes on mini-vans?

if you wnted to launch a honda like that youd need a comparable front wing to even it out... were talking about making a honda fly, wtf is wrong with us...

Zero Friction the Driveline to help get the HP to the ground....
In the Transmission, the U joints, the Rear end, the bearings at the wheels etc...

Reduce the unsprung weight to help when launching, turning, and stopping!
Light weight brake rotors and calipers.
Light weight upper control arms, lower control arms, panhard bars etc...

Balance the weight in the car

Port matching the Manifold to the heads and the throttlebody to the manifold for optimized intake flow.

Port match the exhaust ports on the heads to the headers and make sure the gasket doesn't restrict exhaust flow.

Optimized header design (Tri Y's or more recently Flowtech's Afterburners) even out the exhaust gas flow to optimize power.

Zero friction on the cylinder walls has shown to increase power by a minute amount (also allows for a tighter clearance between the piston and the cylinder wall).

Direct Port Injection, now showing up on 4 bangers from Mazda (Mazda Speed 5) and soon on the Solstice GXP. When used with a Fogger output this will help with atomization of the fuel into the air (biger bang and less to burn off = more power and lower emisions).

Porshe and Borg Warners new Turbo is a good idea for increase power... Single Turbo with Variable angle blades on the impeller. Using High heat resistent materials allows this to be used on Gas powered Vehicles (has been inuse on Diesels for a couple of years). It will be on the 06 or 07 911 turbo.


Maybe match up a heat reflective zerofriction on the intake and exhaust runners in the cylinder heads along with heat reflective zerofriction on the pistons and cylinder walls (direct the heat flow through the exhaust). Then Coated headers and Ceramic Brick Cat's along with a Coated cat back exhaust... just make sure the exhaust tips are pointed away from the body as you wouldn't want to warp plastic and metal.

A certain amount of heat needs to remain in the motor to get the metals to expand to operational temps as well as getting the lubricants to there optimum viscosity. So pulling to much heat out of the motor could have a detriminental affect.

Optimized exhaust flow could allow pistons in the combustion cycle within the engine to make more power as the pistons that are in the exhaust cycle give off less backpressure.

Optimized Fuel air mixture... Optimized Fuel Source (if there is one).

/\/\/\/\/\/\/\/\/\/\ spot on mate. some really ggod stuff!

as for body kits, thye are not deigned to make downforce only look "good", but that depends upon who you are!

the ideas are there! a lower front end pushs the air over the car, reducing the air underneath, thus reducing lift!

Chris.
