any of the commercially available (and even the Megasquirt) electronic fuel injection ECU's can attain the same level of HP numbers if all the hard parts are the same (throttle bodies/injectors)

that was exactly my point. his dyno sheet is from a T1 motor with god knows what throttle bodies and plenums and runners and injectors and heads and exhaust and anything else ...

how is that supposed to make me feel good about spending $2k for his setup? (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif)

i just don't get it. how can you use someone elses dyno-sheet as proof that your injection system is worth $2000 bucks?

am i the only one here that has a problem with that ????

i believe that an efficient engine is a clean engine, but nobody has been talking about making aircooled engines meet 2010 emissions standards.


One of the goals of this efficient engine is to start our way toward clean running aircooled engines... It won't be long until guys like me won't have a job at all unless we are on the ball with efficiency and making the engine more efficient to pass smog checks... I am determined to spear head this one and be ready for the day to come and watch the other guys squirm!

Very easily... But when you have no other choice something beats nothing all to hell... (IMG:http://www.914world.com/bbs2/html/emoticons/boldblue.gif)

... The gearing is being set up specifically to keep this baby at peak torque on the highway ...

not trying to high jack just a crazy question, that i know is wrong.... my fifth gear torque peak is at 4500 rmps with about 165 fp, which happens to be 115 or so mph. does this mean my best fuel usage will be at 115 mph... if so cool i might try to that on a cop if i ever get caught at that speed

and jake i am not arguing with you just using your post for the words

The peak torque is the point where any engine has the best BSFC if it is tuned correctly.. This means that if we get our peak torque at 3K RPM I should set up the gearbox to live the desired cruise speed in each upper gear at that point.... This takes the most advantage of the gearing.

You can try it with a cop and see- might work.. (IMG:http://www.914world.com/bbs2/html/emoticons/blink.gif)
