1. How do I
increase my horse power w/o rebuilding the motor or breaking the bank
(add-ons)?
Effectively speaking, bolt-ons or add-ons will increase the horsepower
of your import motor but has certain limitations. Remember real
horsepower requires moving more air and fuel at a given RPM
| Here
is a list in order of their ability to get these ponies: |
| |
Nitrous
Oxide: |
A 50 shot of Nitrous Oxide is max for stock motors. Exceeding this amount may work for a
while, but you can end up blowing up the motor. |
| |
Headers: |
A good set of
headers should not put you in the poor house. Stick to common
name brands, ceramic will last longer and are a good investment. |
| |
Exhaust
System: |
A good exhaust system
enhances the air flow from those headers you just put on, and
they sound good too! |
| |
Air Intakes: |
We have
tested a number of different air intakes and with all the claims
the figures are just not there. Get something that looks good
and has a brand name. |
| |
Pulleys: |
A good set of
Pulleys not only look good. last longer and have better gripping
pf the belts, but they can increase HP from 8 - 20, depending on
the application. |
| |
Flywheels: |
The bottom
line here is that the lighter the rotating assembly the faster
the motor will rev up. A light Flywheel not only makes more power
but the specs on Aftermarket Flywheels are far better than OEM. |
2. How do I
get that neck-snapping ride I've always wanted?
Now here is a list for you guys that want that neck-snapping ride.
This list is made from the least expensive to those of you that own Fort
Knox!
| |
Copper
Head Gasket: |
That's right,
by reducing the thickness of your Copper Head Gasket to increase compression, it's an easy
gain. |
| |
Camshafts: |
The topic of camshafts can go on forever but the bottom line is, if properly
chosen, cams can enhance total performance. |
At this point things get kind of tricky. Anything from here on
out requires the proper matching of components with some professional
help.
| |
Block
Boring: |
This is
ABSOLUTELY the most power gain you can get. First you have more
cubic inches (there is no replacement for displacement), and
secondly, more HP is gained by increased bore than stroke. Also,
on the imports this unshrouds the valves that allows more
airflow to the cylinders.
More fuel + More air = More power |
3. If I add lots of Nitrous,
Supercharger or Boost, can I put stock components back in the new bored
holes?
This is a good time to keep in mind what you are trying to
achieve. If you are intending to add lots of nitrous, supercharger
or boost, you can't put stock components back in those new bored
holes.
First consider Forged Pistons (if you expect more than 50 HP
over stock).
Second, Stock rods are fine for a stock motor, but if more than
30 over stock, consider replacing them with aftermarket.
Third, If you're adding or have tons of NX or boost, or if you
expect to make over 50 HP over stock then Forged Pistons and new
Connecting Rods are a must (if your making 100HP over stock, it will
require Billet Connecting Rods)!
Lastly, just a note on cranks. Imports have some very good
cranks, some even forged. Unless you are into all out racing and
want to spend $1500-$2000 for a billet crank, stick with the one you
have.
4. Besides boring, what will have the greatest effect on my air
flow?
Next to boring, Heads have the greatest effect on Airflow. Lost of
shops are now offering porting, import matching, reshaping chambers and
polishing combustion chambers. Some of the work can be a little pricey
but even with minimal work its worth the investment, and a necessity for
the big head hunters!
AND REMEMBER, Be realistic!!! With a few basic rules and some
of that hard earned money power gains can be achieved by making the
right parts work together. The best way to achieve your goals is to get
professional advice (you can't talk to a book!). With today's computer
age, use your smarts. The big web site guys didn't get that big,
unless they were doing something right.
