This customer brought in their 2023 Escalade V which is already a beast of a machine, but they knew they wanted more. These are all AWDs so we had to get a little creative in order to get baseline numbers on our 2WD Dyno. By removing the front axle, we were able to to complete our baseline pull with just the rear tires however, there was another obstacle. On the stock tune, the Escalade V has a speed limiter of 125 mph, so we were not able to do a complete pull in a 1 to 1 gear and get an accurate whp number.
Instead, we completed the dyno pulls in fifth gear so we didn’t run into the speed limiter. Because of that, the dyno reported very low power measurements in comparison to what the Escalade V is supposed to make. Baseline peak whp was 507 whp to the rear wheels.
We then removed the engine and sent it out to this customer’s own machine shop where they specialize is building kick ass V8s. The LT4 block was bored out to 416 cubic inches and a complete GP3 cam package was installed along with all upgraded top end components. The supercharger was sent out to Kong for porting, then out for some custom powder coating work (as were the brake calipers to match) and once we received everything back at our shop, it was time to assemble all of the components as one.
In addition to the built motor we also installed a Global B DSX flex fuel kit and a methanol injection kit so we knew this beast would have plenty of fuel to work with because it’s going to be thirsty! And to top things off, we built a custom set of headers from a Silverado header kit from Stainless Works to work with the Escalade V.
After getting everything buttoned up, we got the Escalade V strapped back down tot the dyno. Final power ratings were 735 whp to the rear wheels. Now this may not sound like huge numbers for all the work that was involved, but the baseline whp rating was only 507 whp so the current whp rating represents a monstrous 45% increase in power! We completed the post modification pulls in fifth gear as well so we could have a fair comparison from our first dyno pulls.
There is plenty more power to be had but we were limited due to being on the smallest upper pulley we could install. with a larger lower pulley, this truck has the fuel system capacity to support at least another 100 to 150 whp!
