TEMPLATE SYSTEM FREQUENTLY ASKED QUESTIONS |
QUESTION:
Will porting my cylinders with the SportPort Template System
make my sled less dependable?
ANSWER:
No. Dependability is the number one priority that goes into ALL
SportPort Templates. Race Logic will NEVER sacrifice dependability
for horsepower no matter what gains can be achieved.
QUESTION:
How much performance gain can I expect from using the porting
templates?
ANSWER:
This depends on many factors. Engine displacement, number
of cylinders, modifications made to the engine, engine dependability
concerns, etc., all play an important role in determining how much
performance increase will be seen.
While it is difficult to categorize all engines and porting templates
to individual horsepower amounts, we see typical increases of 10-25+hp,
depending on the model.
QUESTION:
Where do I need to set my jetting after porting with the template
system?
ANSWER:
This also depends on many factors. Altitude, temperature, engine
modifications, etc., all play crucial roles in determining final
jetting.
Porting done correctly, as is the case with the SportPort Templates,
maximizes engine efficiency. This in itself should not affect jetting
requirements. As a rule of thumb though, all modifications should
be followed up by increasing jetting two sizes from current setting.
Then you can begin to drop back down while carefully monitoring
piston wash and plug color. Our experience indicates you will typically
arrive at or near your original configuration.
QUESTION:
What changes will be needed in my Constant Velocity Transmission
(CVT)?
ANSWER:
Depending on how well your clutching is setup to begin with, you
will typically need to increase primary clutch weight. Porting increases
horsepower, which will allow you to load the engine harder, faster.
To realize the full potential of the horsepower increase, you will
need to make some clutching changes. Trial and error, and field
testing are the only ways to properly configure your setup.
QUESTION:
Will my powerband change?
ANSWER:
In most cases, no. As said before, porting maximizes engine efficiency.
Good cylinder porting should not adjust your powerband unless it
is absolutely necessary. Our porting system maintains your original
powerband while increasing horsepower throughout it.
QUESTION:
Will my fuel requirements change after I port?
ANSWER:
No. Although, you should already be using quality, premium gas anyhow.
Our porting system does not change your fuel requirements unless
your engine has had compression altering modifications (i.e. high
compression heads).
QUESTION:
I like the idea of porting my cylinders, but you do not currently
offer a template for my particular model. What do I do?
ANSWER:
We are always developing templates for the new models. Even though
your model may not be listed, we may have one that recently was
completed and has not made it on our site listing yet.
Since manufacturers add new models each and every year, we are always
trying to find ways to stay ahead. That is why we offer the following;
If there is a model where we show a large enough request for template
development, if you send us your cylinders, heads, and pistons,
we will send them back to you with a free template system. This
offer only applies to models that WE feel there is adequate request
for.
If you have a model not listed, submit it for template consideration
by clicking
here. Our future template decisions will be based on the amount
of submissions we receive.
