Here is the latest project we just finished. A rebuild on a pair of 502's with a few upgrades with some great numbers and reliability.
Thanks Mike

how about a pic of the uncorrected sheet w/ the correction parameters... CAT, baro, etc... also... don't see any egts in the headers.... not interested in exhaust temps ?

what madel superflow is that and are you running their software or third party depac stuff ?

Not going to be very reliable with those air fuel readings

Bang!

shiny

Are those valve covers going to fit with headers?

Good evening gentlemen,

I see here that some of you are doubting the latest in engine building technology and the instruments which allow us to test our designs. I am happy to see that you are paying attention to the latest project completed at Roccard Marine.

Just to put you all at ease I’d like to remind you that the industry standard is corrected power; no professional engine builder uses uncorrected data. Here at Roccard, WE do not build our engines out of magazines. We build power using the latest available technology along with using our own proprietary designs and techniques.

Let me ask you folks with doubts, does the camshaft figure in anywhere in terms of how much compression ratio an engine will tolerate on pump gas? Making power is all about volumetric efficiency and cam timing, along with many variables, which smart engine builders employ. We just made approximately 640 hp with 502 cubes and that is 1.27 hp per cube, which is not outstanding power; it is average power. This is 2006 not 1986. By the time the stuff we are doing gets into your comic books telling you it cannot be done, it is already old news here.

Thanks Mike

I would work on your PR and AFR.

As for the afr the jets were bumped up one more size after this pull session.
