Hybrid Fuel Economy
Your article on hybrids had this statement:
"However, manufacturers - including pioneers Toyota and Honda – are now
frequently fitting much more powerful hybrid drivelines to otherwise
conventional cars. These cars achieve performance similar, or in some cases even
better, than ICE-powered equivalent cars but have relatively poor absolute fuel
economy and emissions figures."
This would have made a lot more sense if specific
models were used such as the failed Honda Accord hybrid. But instead, I
instantly thought of the Toyota Camry and could not understand:
"relatively poor absolute fuel economy and emissions figures" mean? In North
America, the EPA ratings for the Camry shows:
MPG / emissions (10 is best)
25 / 6 - Camry
2.4L, automatic or manual
34 / 8 - Camry hybrid
A 36% mileage improvement, 9/25, and a 33%
improvement in emissions, 2/6, is pretty impressive in my book and far, far from
"poor absolute fuel economy and emissions." What sort of improvement is
necessary? What other technology comes close with the equivalent range and
If the paragraph in that article read something
along the lines of "hybrids are not a panacea" for all models, I would agree
especially if the hybrid architecture does not fit well with the vehicle weight
and expected usage. But instead, the wording suggests something that doesn't
seem quite accurate.
"Absolute" does not mean comparative! You are
making comparisons of cars with and without hybrid drivelines. We were saying
that today quite a few hybrids have lousy fuel consumption in ABSOLUTE
terms. For example, any of the SUV hybrids, LS460H, et al. A further point - no
hybrid has yet beaten the fuel consumption of one of the first hybrids -
the Honda Insight. Eight years later that's a bit of a worry isn't
After reading your 2001 article on a 1985
Toyota Hiace (Super Custom)
the editor described how he didn't know what the red "Tbelt" lamp meant. That
stands for timing belt and it flashes on once the vehicle approaches 100,000
kilometers to let you know that the timing belt needs replacement. Also the
musical chimes that turn on after 105 km an hour is a design in 80's era
Japanese cars to remind drivers that they were exceeding the 100 km speed
limit. They have since been fazed out and no vehicle that I know today has this
Boost Control Valve
After reading your article on Brilliant Boost,
I have been trying to find the Festo flow control valve. Do you happen to
have a direct link for purchase in the US or a website suggestion? I
would really like to try one of the instead of what I have been
using. Thanks so much in advance.
Any variable flow valve of the correct size can
I have owned and
since sold an 04 350Z with stock internals that dynoed several high 300hp
at the wheel runs and the highest 406rrhp. The work was done by
Marks Workshop York Western Australia. The work consisted of Vortech
intercooled supercharger, pulley upgrade (approx 11psi), aftermarket
exhaust, water injection. Sold the car at around 45000 kms and engine still
loving life. Could light up first second and third from a standing start (didn’t
have the balls to try fourth). I spent about $90G all up including $7000 worth
of AP racing brakes, lowering etc. Thought it might interest readers who wanted
to save 10G on twin turbos as opposed to a Vortech.
I have tried my local marine shop for the DIY
suction camera mount, but they have never seen or heard of one. Any chance of
the brand name and model, so I can chase this up further?
You might need to find an alternative source
for a large, strong suction cap. Perhaps a store selling rubber goods?
Great article on intercooler (Intelligent
Intercooler Water Spray - Part 1 and 2), nicely written, easily understood. Now
I have a 6 cyl diesel I am contemplating ta urbo for, however the turbo will be
on from 1500 -3000 RM and hence when I am on the highway (100kph +
1800-2000 RPM) it will be on all the time. Wax may not be the answer as turbo is
on all the time. I have limited room to install a intercooler infront or behind
my rad due to a crossmember and 2 horns. What do you suggest?
Regarding The APEXi Power FC Engine Management ECU article
on Apx'i PowerFC, you should check out www.fc-datalogit.co.nz an
aftermarket PC tuning package with datalogging inputs. Brilliant user-friendly
system which allows you to view whole maps and access more advanced features of
the unit not available in the hand-controller.
I just had a question
about a rev limiter/launch control kit, I was wondering if the jay car frequency
switch would be able to used like a bee r rev limiter. At a certain rpm
(frequency) the relay closes the signal to the coil then when the rpm(frequency)
drops it opens the circuit.....also with a switch hooked up to the brake so can
be stalled up and when brake is released just goes back to normal revs....car is
a auto rb30e+t r31 skyline with 3k stall.....
That sounds feasible.
