L99 to slow!!

I'm going to buy L/T headers, dealership tune ,3.73 gears and a cai air intake with air scoop . How much realistic hp/tq can I really get. I can't read those Dino sheets because it's all in rear wheel hp. I'm not good with this so sorry for the ignorance and give it to me simple?

http://www.carsdirect.com/car-mainte...eel-horsepower



Multiply Base Horsepower by the Appropriate Percentage - Automatic transmissions are said to lose 20% of the power from the engine to the wheels, while manual transmissions lose 15%. To determine rear whp, multiply the base horsepower by 0.80 if you have an automatic transmission and 0.85 for a manual transmission. Example: 250 hp x 0.80 = 200 rear whp.

just do a find for X......

heres a site to convert basically everything in the car....I love it myself

Kev, you shift, we don't!!

On average, I'd expect 365 rwhp / 375 rwtq. With a sponsors tune.

Sounds gd. There isn't much gained rwhp in a basic Bolton tune. Just make sure they know what they're doing with the trans. That's the key!

No offense, but that's not the norm. Those are LS3 numbers.
