If I decided to have some loser in some place like Colorado Springs, Colorado build me a motor and dyno it there at 6300 feet elevation and the dyno had a correction factor over 1.26-1.30 could you trust the numbers to even be relevant??? I seem to remember reading or hearing that as far as sae standards go although the numbers are theoretically corrected for such a difference in elevation that they are considered not valid at all if corrected more than a certain percentage from standard deviation. This "engine builder" is also getting some REALLY nice hp numbers from stock bbc peanut port heads with "special" porting, I'm thinking of maybe throwing away my CNC ported AFR 315's and going to some full race peanut ports, would I still make 1100hp or would I lose 1 or 2% of my power, just curious, Smitty

Its amazing how fuzzy math works!

Math says : tiny ineffecient OEM ports + big valves = small pee-pee + big mouth

===================

SAE says +/- 7% correction. AS WV mentioned the math gets real fuzzy after that and thus be discarded.

hey vodoprick how does it feel to have your azz handed to you again

So lets say I claim to be a Colorado springs engine builder and I use the crappiest heads made, port them to death and make 420 hp my corrected hp will be some outrageous number, like 420hp X 1.30, I am now building 546 hp "race" engines??? I could challenge some of the best marine engine builders and performance cam guru's to a dyno show down??? I bet I could lay the dyno's intake air temp sensor on the hot manifold and probably prop my numbers up even higher!!!! I could drop my 420 hp bbc in a 70 Chevelle, go out and run 12.50's and call myself the new king of BBC's??

wow,all the money i spent on dart cnc cyl heads has been a waste,i can make more hp&torque with peanut port truck heads that are done at 4400 rpm,how did this guy get this smart,and figure out how to get big hp out of junk?

Because he listened to 2 idiots named steelchump and cslob(bought airflow cd's and now knows everything about engine dynamics.plus a bonus cd on dyno tech.).

the book Big Blocks For Dummies

Colorado Springs Elevation 5,975–7,200 ft

1 mile = 5280 ft

Colorado Springs features a semi-arid climate as the city only receives approximately 16.2 inches (41 cm) of annual precipitation, which includes rain and snow. Colorado Springs is just east of the Southern Rocky Mountains, which protects the city from extreme weather.

There is an old saying that I use on loser's (that just can't get a grip on reality) like VODOPOO:

Figures don't lie----------only liar's figure.

Shaun, I was waiting for someone to connect the dots between VODOPOO and CSTRAUB. Been sometime since OSO sent him packing.
