Just was wondering if anyone had put the ford hot rod cams in their mustang that has the E-force installed. If not can it be done? Also has anyone put in the optional airbox instead of keeping the stock air box.

It can be done....but not advisable. Hot Rod cams have a profile designed for N/A applications. You'll lose power in you install them in a car with an supercharger. You can get supercharger cams though and that will help power, but I assume you're going for the rougher idle? A cam that's good for taking advantage of boost does not lend itself to a lopey idle, and vice versa.

Not sure of your RWHP goals, but with a good tune you can still get nice power out of the E-force. After upgrading to the 3.5 inch pulley along with GT500 pumps, I am at 455RWHP through the stock airbox. The key is a good dyno tune.

thanks parchisi, yea the car still needs to be taken to a dyno. Upgrading the pulley and making that much horsepower im afraid of the tearing up the stock bottom end, or is it still pretty safe.

I disagree the Hot Rods are not for N/A, they are a slightly more aggressive pattern then stock and will work well with a positive displacement blower.

For the OP's benefit, more aggressive cam specs don't necessarily mean better for FI. More duration and lift will allow more intake charge into the cylinder, and I'm not sure how the LSA compares to stock, but more duration and lift will also create more overlap and less efficient use of boost.

Like I said before, they will work, but they're not ideal. Best bet is to get a set of dedicated blower cams to get the most out of your supercharger. I don't know for certain, though, if the Hot Rod cams will net you more or less than a stock cam would with a blower.

For example, I originally built a 408 for my 1995 GT to be N/A. Eventually I threw a supercharger on it and was pretty disappointed that I only got 430 rwhp. I replaced the camshaft with a custom grind blower cam and gained 100 hp with the cam alone. Now that was an extreme case going from a N/A focused cam grind to a blower cam profile, but it demonstrates the benefit of getting a camshaft designed for your application.

Unless you're using a double negative, are you saying the Hot Rod cams are NOT for N/A? I'm pretty sure they are...

"Engineered specifically for naturally aspirated applications by the same designers of the stock camshafts"

Got that right off the description on the FRPP website.

well thank you for the extra info, i certainly am not looking for loss of power, do comp cams the ones sold on AM do any good for me?

parchisi

You won't necessarily LOSE power, and I think that's the point SpartaPerformance was trying to make, but there are specified blower cams out there for FI applications, like so...

Looks to me that AM only has N/A cams.

Also notice the LSA of the blower cams vs the Hot Rod cams, 115 vs. 110.
