    Arneson Surface Drives

    Thanks Mike. You brought up some important points that I never thought of.

    The future of the engine as we know it

    Great thread guys. I haven't read the whole thing..but here's my $0.02. Has anyone talked about valving technology? What I'm thinking is that a variable electronically controlled valving scheme could drastically change how the IC engine operates and how we "humans" can use the power. From...

    Top Fuel Dragster

    Reduced frontal area is an important factor in the equation for speed. The smaller hole that you punch in the air, the less wake you will make in that air. Making a wake means stirring up the air, creating eddy currents and low pressure areas that induce drag, slowing the vehicle down. It is...

    Top Fuel Dragster

    Sorry guys but I have to clarify Metalguy's last comment. Frontal Area is equivalent to streamlining. I think we are thinking the same thing. The more air you push @ 330mph, the more power it takes. Since the dragster's have less air to push, they go a tad bit faster. The funny cars have...

    Top Fuel Dragster

    Great topic..you guys are really riled up..thats cool. On the topic of the nitrous..I was under the impression that the true reason nitrous helps develop more power was the cooling effect generates a higher O2 concentration in the charge, not the preceived chemical boost. All it does it help...

    Diesel Power

    as mentioned by icrman, the HP will be the same or less, depending on friction/windage losses. The more important quesiton is how can you make up the loss in RPM with different prop? Given you are using the same drive, you should be able to prop up quite a bit. You might sacrifice low speed...

    Arneson Surface Drives

    Thanks guys for your postings. There is another company...www.q-spd.com out of New Zealand that makes a similar setup. What is really bothering me though, is that if the surface drives have lower drag, less moving parts, better efficiency, and comparable performance of a stern drive, then...

    Arneson Surface Drives

    Greetings all...I would like to discuss the concept of surface drives and why Arneson is the "defacto" standard in the industry. The concept is not really that hard to grasp, pipe the power straight to the prop, keep the prop half-in/half-out, and be able to steer. I got a quote for a pair of...

    Electro-Mechanical Valving

    aspearin1, Thanks for the response. Your right, I have no idea of the wear conditions of this type of solenoid. Not being an EE, I don't know if this type of solenoid is even possible. My guess is that it would have to be electromagnetic in nature... But theoretically speaking, the solenoid...

    Electro-Mechanical Valving

    Well, I guess I'm not worried about the electrical side of things. This is how I picture it. There's an electrical actuator atop the head, that can instantly open/close the valve, with tremendous force. The forcing function, would have to be tailored to allow a "soft" closing, therefore not...

    64-bit questions

    FYI.. Hello Andrew, We do not yet have a version of SolidWorks that is compiled for 64 bit OSs that is ready for commercial release. The Operating Systems are also a bit rough around the edges at this point as well, truth be told. SolidWorks posts announcements like this on out website...

    Flame speed

    25362, No person, other than a PHD in Chemical Engineering, can completely comprehend the physics involved in combustion. Thanks for the link. It was very interesting, although not very understanding for those of us with lesser intelligence. Again, thanks for the post.

    Electro-Mechanical Valving

    Team, As a student of classical IC engine theory, the CAM has always been of interest to me. Has there been any threads considering the use of Electro-Mechanical Valving? The last I knew, there were a few R&D efforts underway in this area. If you can get by the amount of energy it...

    64-bit questions

    Chris, You mentioned the slowness of opening models. I am wondering how large these assemblies are? If those assemblies are large, 10Meg or greater, then your disk selection might be critical. If your into SCSI, then go with 15K disks, and a RAID 0 config. If your into SATA, then you could...

    64-bit questions

    Jeff, I will agree with you on the bus architecture. I still think that the EPIC instruction set is superior to the AMD. If Intel could be get more apps to compile under EPIC, then we might see some rather interesting results, especially in Floating point. I am used to dealing with CFD...

    64-bit questions

    I don't think Arlin is correct, saying that AMD has the only commercially available 64-bit proc...Sorry, Itanium2 has been out for quite awhile now. And you can get XP in 64 bit form right now. As for SW being 64-bit compiled? I don't know. From a performance standpoint, there is no...
