It is approximately 36whp (proven so far) - Here is Jaekeem's dyno with the listed mods above and a K&N drop-in which adds approximately 10whp:
The car currently has a prototype exhaust which is crush bent and very restrictive with diameter as small as 2" - also we have not tuned to the full potential. We kept the same settings for before and after dynos in order to show bolt-on gains only. With more aggressive tuning and a mandrell bent cat-back, the car should make 45-50whp from Downpipe, JB Stage 1, and Cat-back.
