Ls1-5.3 power loss? On a nearly stock engine (L33 5.3) with a mild 212/216 cam and nothing else, what do you feel the power loss would be by removing the truck intake in favor of the lower/better looking LS1 intake. I would like to keep costs down and since I can purchase a LS1 intake for $30.00 I figured that is pretty low cost. I need to change the water pump and pullies to Corvette style anyway. Am I losing 5 or 15 crank HP?
By the way this is going in a very light 2250 lbs car.
What do you think?

No one knows? Way to much knowledge in here to stump the crowd with this.

the LS1 intake doesn't flow enough above a truck intake to really see a difference in HP with a truck, and he'll lose a bunch of torque. so if you stay with a truck youll be more satisfied. remember when you step on the gas hp is not what pinns you to your seat its torque. keep the truck intake or you will be dissapointed.

If its a clearance issue, then its kinda irrelevant right? If the truck wont fit you have to do it. I did, running a bone stock 5.3 in a camaro with the ls1 intake. Seems to move the car around pretty good.

I guess the other question would be, what is to be gained by using the better intakes. If I save $400 going LS1 intake but lose 5HP or spend the $400 and pick up 10 then the 15Hp is worth the extra expense.
