Originally posted by graphicgr8s RML I was just jesting about the oil change, Thought that was quite obvious. Fact is I built my first 500+hp engine at 14. And designed the cam.
Hmmm,At the age of 14 you built a 500 HP engine and designed the camshaft...
Can't help myself for wanting to know more of the details here..would you care to share and elaborate?Who ground the cam for you(I may know them)?Type of engine and cylinder head configuration(combustion chamber shape and volume and valve sizes and valve train components would be helpful).Cylinderhead info like port volume and shape,flow numbers(measured at specific valve lift increments on a flow bench would be helpful). Plus the cam configuration and type,hydraulic,solid lifter,solid roller,hydraulic roller or even mushroom tappet style.Don't forget other important info like lift,duration,separation angle,overlap and lobe center lines all needed and more to design a camshaft.What ratio of rockers and styles used?.Did you stagger your rockers(an accepted way to change a camshafts profile some)?It would also be helpful to know bore and stroke,rod length and assembled squish and static compression ratio of your engine.Also was this a naturally aspirated or forced air induction?Some info on your induction set up would be nice to know.Nitrous?an easy way to 500 HP for many...
At what RPM was the 500 HP achieved?Max RPM's you saw with this motor..
And just what was the intended purpose of said engine,street or race or both?
Having designed several myself and being an engine builder your statement cries out to me.I started at an early age also but had to wait till I was 30 to build my first 5000 HP motor(not a typo mistake...five thousand horsepower) from 500 cubic inches....
Although 500 HP today is almost so easy to do for experts and some novices considering the components available today off the shelf but most home brew motors fall way short.....
So considering all the variables in producing an engine that "really"produces 500 ponies what was it that made you want to decide at the age 14 to design your own when most camshaft manufacturers have such an extensive line-up available to meet 99% of the engine builders out there?Is there anything that you would know at the age of 14 that would trump a experienced camshaft maker/designer?
OH,almost forgot,did you measure the output of this engine?Dyno or track?Or was this just a "guesstimate"?
Not wanting to discredit your engine building ability here but making a statement that you deigned a camshaft for a 500 HP engine at the age 14 makes me want to call BS(not that it is impossible but just not probable) on this claim unless you can explain the specifics on the said claim...most camshaft grinders I know would discourage any major changes to accepted designs unless specific parameters are discussed and met as they have already seen most engine configurations.....
Also how long did it last?..........
