Turbo_calc:
WIN32 Binary
A small piece of software
done after reading "
Turbo Chargers" by
Hugh MacInnes.The
software depends on the
FLTK ToolKit
(small and easy to build and use).This software is released under the
GNU GPL, tested on Linux and Win32 (mingw).
| Description: Given size of the motor, rpm, air
temperature, pressure ratio, efficiency of the turbo and intercooler
and pressure drop the software compute CFM, temperature, density
...etc... |
Current car project:
Zezette's
Car Specs:
- oversized hybrid space frame and back-bone chassis (steel RHS and
tubes)
- transversal motor rear wheel drive (1.6 16V Nissan - about 100
BHP)
- dual wishbones (front)
- fully adjustable geometry :
- castor and slip angle.
- quasi-constant wheel-base under load.
- adjustable rocker factor.
- variable height.
- possibility to go to progressive suspension acting on the
geometry (like ProLink, MonoCross, FullFloater...etc...).
- possibility to modify to 4 directive wheels (such as car races
on ice) or like Lotus Elise.

Sleeping for one year....
- strengthening (second stage) the main beam
(planning done)
- strengthening (second stage) passenger and
driver part (in progress)
- front suspension (planning done)
- steering, arm, wheel hubs (planning done,
parts to buy)
- rear part with motor ...etc... (done)
- rear chassis (planning)

My Low Cost Tuning for SV:
It just take little money to change a dangerous bike, with a safer and quicker
one.
Before getting some BHP, have a look to tires, fork, brakes, shocks...
Fork, Brakes:
- Modification of the fork, too soft and has no valve. Replaced
oil with 20 W SAE and White
Power progressive springs (I did not put the shims, too hard). Cost
15€ (fork oil) Cost 120 € (WP springs).
- Change front brake pads with EBC Metal. It is really easy
to do stoppies while you do not want to do this ;-). Cost
50€
- Change front brake fluid each year and regular airbleeding. Cost
15€
- Modification of the height of oil of the fork, added 50ml of
SAE 20W in each fork leg (above recommended height described in the
manual of WP springs), I fully relax the progressive spring (about 30mm
of SAG bike only, with me add about 20mm of SAG). Result softer on the
first 20 mm and after lot of margin when really pushing on the front
brake, better cornering. May be a little bit too hard, but this is too
soon to have a definitive answer, not done enough miles. Cost 15€
After let's take some BHP
Engine:
- Removed
ignition retard see links before. It is difficult to feel the
difference but seems to be better on 2nd and 3rd gear,
safer for the
rev limiter. Cost 0€.
- Added 2 degrees of advance on the ignition through modification
of the pick up position. An huge improvement in low and mid-range RPM.
With this modification the old SV
accelerate just like a 650 K5 SV with a Devil exhaust. (I should add 2
more degrees) Cost 0€
- Modification of the snorkel of the air filter, remove about 30mm
at the
near end of the inner pipe (One time i remove the snorkel, loud sound,
no more torque at low revs... unefficient in my case). Helps to have a
broader and higher "chord" from 7000 until 9000
rpm and at the same time, less clogging of the air filter. Cost 0€.
- Modification of the tank support through 2 shims of 5mm, helps to
air breath the little motor. With the previous modification (and next
one), you will fill the change. Cost
0€
- Modification of crankcase breather pipes on the air box,
because
my SV was eating so much oil because I love to push. The trick is
to
adjust at least the 2 pipes connected to the airbox (drill at least to
the diameter of the internal pipes, which is not done by Suzuki....),
and you can also add two more
pipes (my case). The little motor push like a bull until the rev
limiter. Slightly less need to add oil. Cost
3€ (aluminium tube of 10mm in a home depot)
- Change spark plugs with colder ones (NGK Something 9). Cost 20€
- Modification for the "depression hat" of the carbs, drilling
bigger
hole (1,5mm if i remember). Result better throttle
response. Cost 0€
