30rwhp and 40rwtq are impressive numbers for bolt-ons. Providing you're replacing major components like cylinder heads, camshaft and/or intake. If not, I would have to see dyno graphs to get a better understanding how that is done.
All stock heads and internals. Power was gained simply by improving volumetric efficiency.
Ive replaced the intake, throttle body, and ported the intake manifold. Its got a full headers back exhaust, larger injectors and a catch can. On the stock tune no less. I am working out a day to get it tuned on the dyno but the military is getting in the way again lol.....
Anyway the 3.7 is known for making as low as 155 rwhp in the liberty to as high as the lower 170's. Just depends on drivetrain. Mine made 192rwhp and 213rwtq with a really broad power band.
As I said before I wish I had it on the dyno stock to see what it did stock. And for every mod I've completed.
To put that power figure in perspective tho Ajag's 3.6 in stock form made 185awhp
