Stock power figures.
Hi guys , not sure if this is the right place to post this , but here goes.
My son and i run a tuning and fab shop in England , we work with importers of US vehicles and have been getting more involved with tuning and performance upgrades .
We are currently doing a 2011 Challenger Hemi , its got Stainless works long tube headers , full Borla system with sports cats .
I have the latest HP Tuners set up are slowly working my way through it tuning wise .
Ok the question [s] , we dynod the car as it was presented to us with a very bad cat back system , the results were ok approx 345 lb ft and 330 hp flywheel , i know the official figures are 370 and 400 .Ours is a genuine 49000 1 owner car and runs sweet.
The headers and cat back have given approx 20/25 hp and tq increase , a little bit of work with HP Tuners and we are knocking on the door of 400 tq and 380 hp.
The car is auto and we are are using UK 95 gas , .
So are the factory figures accurate etc , what are you guys getting on your cars.
Our dyno is a MAHA quad roller with sport devices SP5 DAQ , it gives really good results on every car we have done in the 3 months we have had it.
Thanks in advance
