Once we inserted the cam specs into the program, we then ran the ProIterator for both peak horsepower and horsepower under the curve, to see how close or far the chosen camshaft’s specs are from ideal.

Go to my.chevrolet.com/learnAbout/bluetooth to find out which phones are compatible with the vehicle. month = calendar.getMonth(); Any calculations should be double checked before making any engine building and design decisions. V8 Engine Only. Having a custom-diameter LS piston made isn’t a huge undertaking these days, and we’d need a custom piston anyway to bring the LY2’s OEM compression up from its meager 9.1:1 factory compression ratio for this comparison. Always use seat belts and child restraints. After all, what's the point of adding performance if you can't enjoy it. The actual numbers from the dyno cell were 510 horsepower at 7,600 rpm, and 398 lb-ft at 5,400 rpm. date = calendar.getDate(); The most critical part of setting up a simulation is, well, the set-up. We’ll also be diving into the forced-induction component of DynoSim5 as we see if boost changes the outcome on the 5.0 vs. 5.0 showdown. Interestingly enough, DynoSim5 will allow you to create configurations with up to three valves per port, for a total of six valves per cylinder. Before you buy a vehicle or use it for trailering, carefully review the Trailering section of the Owner’s Manual.

While that might sound like a fairly large overbore, there are quite a few instances of the 4.8-liter blocks being bored to the factory LS1 bore size of 99mm or 3.898 inches and living. For the camshaft, we simply pulled up Comp Cams’ website, and used the specs for the 54-469-11 LSR, Rectangular Port camshaft, which has been designed for all-out power in the 2,000-7,000 rpm range. We can help you with either. (Small Block After entering all of our variables, we came up with a compression ratio of 11.32:1. There is also a manual horsepower boost adjustment in the Nitrous Augmentation field. // April The final, and probably most important and useful category is the Camshaft category.
