Finally got my truck on a dyno. Stock setting (pre TN BB install) was 200HP at the wheels. Post TN BB install it dropped to 160HP
It did not seem to want to make any boost, only hit 16PSI, compared to 20+ prior to turbo install. We checked for leaks in up pipes and turbo etc, but none noted? Then DP 80e tune pre TN BB install hit 260HP and only 270 after install?? Boost was 25+ before and only 22 after. Same results with 120r tune. I did note that EGT was only getting to 1100 after turbo install compared to hitting 1300 before. Driving truck on the road, really notice the difference after turbo install, really spools quick and no problems lighting the rear tyres
Questions; How much HP do you loose from engine to wheels, stock is stated as 235HP? On the dyno runs after turbo install I noticed truck climbing up onto front roller, will this impact results? Is it normal to see drop in boost after installing larger turbo (but it moves more air)?:dunno:
By the way, it is an awesome sound compared to stock, sorta howls until it hits around 6-7psi boost and then the whistle is jet like. My ears are still ringing from the dyno runs. :woot:
