POWER TIPS:
Big Power - Focus where it matters
By Don Terrill (c)
When trying to make more power, it's very easy to waste
a bunch of time on things that don't matter. The
following lists will help to focus your time and money
- Do these first and then consider other areas. Rules
may limit some of your options, but these are the
biggies.
The Engine:
1. Power-Adders - Considered by many as the easy way
out, but you can't deny the results of nitrous oxide,
blowers and turbo chargers. In fact, HP per Dollar,
nothing beats nitrous. I know many racers will have too
much pride to consider power adders, but there's still
no doubt their position for this list.
2. Engine size - Unless there was some really good
reason, why would anyone build a 289 Ford, 327 Chevy or
396 Chevy? With the current price of aftermarket
stroker crankshafts, there's no excuse for not building
big.
3. Intake & Exhaust - Like the cliche' goes, an engine
is just an air pump. So, anything we can do to increase
the amount of air entering and leaving the cylinder is
going to increase power. Follow the air path - hood,
air cleaner, carb, intake, heads, headers, mufflers and
tailpipes.
4. Compression - The need for better fuel and added
load on engine components make this no free lunch, but
there's no doubt the power potential of increased
static compression.
5. Valve Events - The right camshaft and rocker ratios
will maximize the amount of air that is compressed
before combustion. Valve timing is half the equation in
calculating dynamic compression (static compression and
valve timing).
Now that you've got the power, don't waste it.
The Car:
1. Weight - Nothing lightens the load quicker than
actually lightening the load. If rules permit, or there
are no rules, why not choose the lightest car possible?
You can also trim weight from your current car - start
at the front of the vehicle and work your way back.
2. Hook - It doesn't matter if you're stock car racing
or drag racing, all the horsepower in the world is
worthless if you can't hook it.
3. Gear ratios - Every engine has an optimal rpm range
- torque converters, transmissions and rear gear ratios
can all be adjusted to keep an engine in that range.
So, if you're starting from scratch, why not build the
biggest engine, put it in the lightest car and then
bolt on your power-adder of choice?
