I see some guys have the FRP HotRod Cams installed on their cars along with the Whipple HO.
Does this install require a complete dyno reprofile of the tune?

I love the sound of the cam lope, it's already enough to entice me to get them, but do they actually give a Whippled motor anything in terms of power?

excellent questions.

imo, the only way to really dial in the tune
100%, is a custom tune with dyno
testing/tweaking.

no. you would not install HR's for power, only
for the sound.

I figured as much. Just wasn't so sure of what the cams were doing at the top end, if anything.
May as well get Lidio to do it all then I guess.

There are blower grinds that will give gains up top but certainly not the Hot Rod cams which have too much overlap for forced induction.
The OEM cams would do better than HR cams under boost.

I wouldn't care if the HR cams didn't give me anything at all but I wouldn't want them to hamper the motor. Do FRPP do a HR cam suited to the whipple? i mean, seeing as they market the whilpple too an' all.

hammeron

no hampering at all. i made 467rwhp / 458 ft-lbs
with 10psi. now the question is, "is that power being
produced with peak system efficiency?" no, of course not.

peak system efficiency is not the goal, the goal is
to run at a predetermined power level (450-475)
and enjoy the side benefits of lopey cams.

Agreed 100% I have no desire to push past 460rwhp on my stock longblock.

Thanks for your help guys

hammeron

you are welcome marcus and good
luck with the project.

I felt a difference with the FRPP Hotrod Cams. Especially around 3k+, granted not as much as a custom grind cam but for spending $700 I'm happy with the power I got. Ford claims 20hp on stock heads and 40hp on machined heads. Now how they work with a blower I had not a clue. I'm interested myself just incase I decide to ever go that route. My cams idling @ 750rpms turns heads everywhere I go.

this was from somone on the bullitt forums who thinks there Thumper cams were causing there clutch issue... So blue is old and red is new. This is Thumpers to the custom grind twin screw, so i would have to think both do help as compared to stock, as the brenspeed custom twin screws are "known to make 30 RWHP." So if you used that as the baseline, assuming the 30HP gain from the customs, he made about 19HP from the Thumpers.

Your not going to notice 11HP at your foot (much) but eveyone notices the difference in sound.
