All,
Long time no visit. I am working on a flat 6 cylinder (Porsche) adding a second set of injectors. Due to location a "fuel rail" is impractical and this prompts my question: Are short fuel lines (-6) from a central supply block a big problem? I do understand the fuel in this line is...
Hello all,
I hope someone here has detailed info and flow rates for a wide variety of fuel injectors. A link to a web site with this info would be just fine. I am trying to make some good decisions on a purchase and this info is all but impossible to find, so far.
Thanks,
PFM
Hello all,
Please help the rookie with a question, I have several ASMI Nozzles I know they were used on a high end air flow bench, I have some doccuments on them but no CFM numbers. The info is as follows, Effective Area .484823, Actual Pressure Ratio 1.049138, RH? 38.24, Mass Flow 0.071831...
Hello all,
I am trying to find a correlation between Horsepower per cubic inch and Volumetric Efficiency. I read that some prostock engines are making better than 2.5 HP per cubic inch at 9000 plus RPM. Is there a path back to VE from this as a start?
It's the math problem again :-(

All,
I have seen in print an article discussing valve float due to rapid engine acceleration at an RPM below that at which valve float occurred under a slower acceleration rate. I have seen evidence of this in engines on track that used low gearing and hard acceleration. I believe I have seen...
Hello All,
I need some help on one of those what is more important in the production of horsepower, compression or airflow? At what point does a reduction in air flow, due to piston valve relief, overcome gains in compression due to piston shape?
OK the picture is this, the piston is a near...
Hello All,
Can any of the oh so helpful persons offer any help on the proper prep for a used Nacasil Cylinder? Diamond hone? Soft hone? No hone you must use new. I think I have heard them all and none ring true.
Thanks in advance.
