    What is it about those exotic engines?

    in Non Tech Board

    Posted

    Alrighty.. let me chime in..

     

     

    Formula One cars and Ferrari's sound sooo amazing simply because of the tremdously small pistons and small stroke...

     

    The Ferrari F40 for example is a 2.9L V8 with a 82mm bore and a 69.50mm stroke... this rev's up to 10,000 RPM... and produces some 478 hp

     

    Formula One engines and (quote from formula one.com) "the 'power battle' of the last few years saw outputs creep back towards the 1000 bhp barrier, some teams producing more than 300 bhp / litre in 2005, the final year of 3 litre V10 engines. From 2006, the regulations require the use of 2.4 litre V8 engines, with power outputs likely to fall around 20 percent.

     

    Revving to over 19,000 RPM a modern Formula One engine will consume a phenomenal 650 litres of air every second, with race fuel consumption typically around the 75 l/100 km (4 mpg) mark. Revving at such massive speeds equates to an accelerative force on the pistons of nearly 9000 times gravity. Unsurprisingly, engine failure remains one of the most common causes of retirement in races."

     

     

    The old turbo formula one engines were a 1.5L V10 .. thats right 1.5 L!!

     

    For 2006, the engines must be 90° V8 of 2.4 litres maximum capacity with a 98 mm maximum circular bore, which imply a 39.7 mm minimum stroke. They have two inlet and two exhaust circular valves per cylinder, are normally-aspirated and must have a 95 kg minimum weight.

     

     

    Thats right .. a 39.7mm stroke.. OMG

    copper intercooler piping?

    ummm..

     

    copper is a soft metal.. soo i dunno about that

    "Generally speaking, aluminum seems to be the material of choice for all automotive heat exchange, but there are other materials that offer distinct advantages and disadvantages. Silver, for example has a lower coefficient of heat than aluminum, and will support more heat exchange in an otherwise identical situation. The price increase is surprisingly small as well. For air to water cores, copper offers even better heat properties at a fraction of the cost of both aluminum and silver. Unfortunately, due to copper's corrosive properties, it generally isn't appropriate for street use in an air to air situation."

     

    Soo.. I guess Copper has very bad corrosive properties.. which is a no no

    What the hell.. cracking exhuast manifolds??!

    Umm.. so I went to the Colorado State Patrol track event yesterday.. and after ohhh several several laps.. keeping an eye ont he coolant and oil temperatures.. all of a sudden I hear a CHOO CHOO CHOO CHOOO like a damn train.....

     

     

    The exhuast runner on cylinder 5 cracked and blew a little hole!!

     

    what the.. have you guys seen this before??

    Just interested .. Hydrolic or Electric paddle shifters

    in Drivetrain

    Posted

    I was curious if any of you guys knew about the paddle shifters similar to the new Ferrari's, Lambo's, World Rally Championship cars, Formula One cars, etc

     

    then if I could apply this to a Z .. now this is just an idea.. I know this would cost like $3,000 + but its an interesting concept..

     

     

    Now does this consist of a sequential transmission and hydraulic valves mounted on the transmission to the paddle shifter?

     

    Or are paddles typically purely electric, and then fire up a hydraulic actuator?

    or is it purely electric?

     

     

    Anyway.. i figured for a pure race bred Z (someday i might consider building one many years out) could this type of system be imposed?

     

     

    http://en.wikipedia.org/wiki/Semi-automatic_transmission i found some info on this site.. actually alot after i posted this thread.. but i was hoping guys with experience could chime in

    you guys have given me SUPERB advice...

     

     

    ughmm.. but one problem.. I had the boost controller on *cough* BACKWARDS *cough* ..

     

    I know stupid stupid move.. but its so easy to mix up..

     

    Im going to pick up some more vacuum lines in a few minutes .. the battery stopped holding charge :(

    awsome man! yeh someone is always home around here.. especially since my brother is out of school.. LoL..

     

    Sorry about the PM's .. I had about 250 .. so I erased a whole bunch of em..

     

    my appologies about that ..

     

     

    Thanks again! The PM is open for messages now =)

    Drilling a vent hole in the MBC

    I totally removed the MBC from the system and am running 5psi and it stays at 5psi.. no spikes..

     

    then the mbc is on.. loose or tight ant 20psi again

    I have searched all over and no one has given me a good answer..

     

    I know the MBC needs to be hookd up properly.. but even the Joe MBC has no instructions to check..

     

     

    Does the bottom fitting one go to the wastegate or vacuum/boost source? LoL thanks guys

     

     

     

    Im willing to bet.. the MBC is on backwards
