Mustang DAN Posted February 26, 2010 Report Share Posted February 26, 2010 Has anyone installed the FRPP HOT ROD CAM PACKAGE FOR 4.6 3V on a Shelby GT? If so, what were your experiences in terms of power gain, sound, driveability etc.? Link to comment Share on other sites More sharing options...
kahmann Posted February 26, 2010 Report Share Posted February 26, 2010 RacerX has them installed. Hopefully he can chime in. From what I've seen of them, they sound killer and are good for 20-30 HP. They have a decent lopey idle. If you're planning on adding boost in the future, call Comp. If not, FRPP is the way to go. Ken Link to comment Share on other sites More sharing options...
mikewheels Posted February 26, 2010 Report Share Posted February 26, 2010 My friend had a set installed last fall at Tasca. He also has 4.10s, delete plates, throttle body spacer, intake, hi-flow cats and stinger mufflers. After a custom tune it dynoed at 302 rwhp. Has a nice lope to it. Cost about $1,500 installed.

Mmmmm... "lope".... There's just something about that sound, right? I was sitting at a stoplight next to a late 60's Camaro a few weeks ago, and it was cammed HARD, just a killer sound. The HP gains are just a bonus...hahahahaha... Jer Link to comment Share on other sites More sharing options...
springer Posted February 26, 2010 Report Share Posted February 26, 2010 Has anyone installed the FRPP HOT ROD CAM PACKAGE FOR 4.6 3V on a Shelby GT? If so, what were your experiences in terms of power gain, sound, driveability etc.? Have it in mine, actually I have the complete FRPP Hot Rod 4.6L engine. They claim with the FRPP heads and cam you up the ante about 60 to 70 HP. That's about $4,000 for parts, plus labor. You can add a blower for that price! The cams work great with the Whipple, and sound like something out of a late 1960's musclecar. Link to comment Share on other sites More sharing options...

Jer Posted February 26, 2010 Report Share Posted February 26, 2010 ^Not the late 60's cars I build, but yeah it's definitely an improvement over stock sound Well, I'm not a "Government Motors" guy THESE days, but 60's Camaros? Or a split-bumper early 70's? I'm in. I'll park it right next to the SGT in my garage! Hell, my wife wants an El Camino SS, and I'm inclined to FIND her one! Barrett-Jackson sold one here in Vegas a few months back for a HECK of a nice price, and I almost bought it to surprise her (she was outta town on vacation). Talk about a cool thing to put a big red bow on in the driveway! Cars are cars, politics is politics. Hahahahaha.... Jer Link to comment Share on other sites More sharing options...

They will change the sound, but the power gains will be nothing with the whipple. If I did not go SC I would have done cams and built the engine up.

mikewheels Posted February 26, 2010 Report Share Posted February 26, 2010 The rpm range for the cams is less than where the Whipple makes max power. That's why they don't add much. To get any more, you would need cams that needed springs, retainers and cam phasers to handle higher revs with the increased lift and duration.

They will change the sound, but the power gains will be nothing with the whipple. If I did not go SC I would have done cams and built the engine up. You know, I heard that from one source. I can tell you that my car was the first to have a tune from FRPP for the Hot Rod cams with a Whipple. I don't know where all these rumors start, but it is an urban legend for sure. Those saying that the cams won't work are incorrect. Next time you hear that comment, ask them what it is based upon. My car was dynoed with the FRPP tune at Gil's in Las Vegas. The FRPP tune came back at 526 RWHP. It was a tad lean for my liking, was fine-tuned again and ended-up at almost 500 RWHP. Most of the GT/SC's are dynoing at 475 to 485 RWHP. Anyhow, the Hot Rod cams work great and sound great, but for what they cost with installation labor, I don't know if it is worth the expense for 25 or 30 horsepower. Installation labor, a new tune and the cost of the cams would probably cost close to $1800 or more. Link to comment Share on other sites More sharing options...

This sounds correct, you can only get so much out of this setup with or without the stock cams. But, the FRPP Hot Rod cams do work with a Whipple, and actually, they work quite well.

kahmann Posted February 27, 2010 Report Share Posted February 27, 2010 For those that can read a cam spec sheet, it's pretty obvious that the Hot Rods weren't built with boost in mind. They have an NA grind and a dirty lobe separation angle. Glad to hear that they're working out well for you though with your Whipple. Ken Link to comment Share on other sites More sharing options...
springer Posted February 27, 2010 Report Share Posted February 27, 2010 Thanks Ken. They work for anyone that have them, just not me. They weren't designed for blowers, but neither was the stock cam. They do work, it is like magic. And, if I were looking for more power with the Whipple, there would be many other things on my list first besides this cam or any cam. Internal upgrades would be my first priority. The point I was making is the Hot Rod FRPP cams work with a Whipple and work very well. Minimal HP gain, but for the speed shops to say they won't is incorrect and rumor. For them to say that you would notice minimal HP gains would be correct. My car is plenty, plenty fast for me the way it is now. Link to comment Share on other sites More sharing options...
greaser Posted February 27, 2010 Report Share Posted February 27, 2010 one thing we are forgeting to mention is the curve of power and torque. peak HP is fine and dandy if all you do is strap it to a dyno but if by adding the cams you noticably increse the power curve over the whole rpm range would be a good investment in my eyes.(if the followers can handle it huh ken) Link to comment Share on other sites More sharing options...
ShadowLands Posted March 1, 2010 Report Share Posted March 1, 2010 It is not a matter of "if they work with a Whipple" or not. Most shops will tell you that there are other grinds that work BETTER than the Hot Rods with a blower. Most cams will "work".....the real question is whether the profile is right for the application. Bottom line is that you're happy with them. 'Nuff said. Link to comment Share on other sites More sharing options...
