1quicktruck Posted December 17, 2010 Report Share Posted December 17, 2010 From what I have read on here the long tubes give more horsepower than shorties. I wonder if the cats were deleted on shorties would that make any difference ? Quote Link to comment Share on other sites More sharing options...

1quicktruck Posted December 17, 2010 Author Report Share Posted December 17, 2010 I checked out your gallery. whats your setup? I see its blown.... Shortie,no cats , magnaflow 2 into one and dyno tuned. Had fast chips in tulsa. Here are some numbers after 86k miles. On a rainy day , he said numbers would be low 348,8 and torque 426. This is at the wheels on 5.3 . He said the formula was 1.2 x 348.8 to get crankshaft hp. He said I should have more on a dry day maybe 10 or so.. I saw somewhere that it is true that on a clear day and no rain you will get a higher reading but I was curious as I see that shorties are only good for 8 hp where long tubes are good for 23 hp. Just wonder if the cats were deleted on shorties if they would post better numbers ? Quote Link to comment Share on other sites More sharing options...
