FRPP Hot Rod Cams Installed

OK, hopefully I don't miss anything here.

Yes my gas mileage has definitely improved, about 2.5 all around but I think when I get some highway miles I will see big mpg gains there. I haven't done enough highway driving with them yet to know for sure.

On the final dyno pull my car was still making power right up to 6200, so while I gained 47 peak, it is somewhat less in reality since the baseline pull stopped at 6000 rpms, although the stock curve looks pretty flat at that point. I bet if he pulled the dyno longer I would have even bigger gains judging by the graph.

I do have a dyno printout but my scanner is not working, I will post it when I can though.

I didn't lose much, if any torque, but I didn't start seeing any gains in torque or hp until around 3000 or higher.

FRPP claims that a tune is not needed and that I could have used the Brenspeed tune but they say you won't gain any power without a dyno tune. They were right that the car did run without tuning but it is necessary to be streetable regardless of what they, say in my opinion. The car stumbled down low and the drive by wire needs major adjustment because of the choppy idle.

I am guessing that I saw such big gains since I went from a canned tune to a dyno tune, so that is another reason to spring for tuning.

My final peak numbers are 325hp and 316tq on a Mustang dyno. From what I have been told my numbers would be anywhere from 5-10% higher on a dynojet but who knows. All I do know is that I got big gains from stock on the same dyno with the weather correction factored in by the dyno. From what I understand this compensates for any weather changes from the baseline to the final pull.

I paid $450 for the install labor. Plus a few dollars for 2 cam phaser bolts (required) and 2 valve cover gaskets (doesn't hurt to be safe). I paid another $450 for tuning, including the baseline.

With the specialty tools the front covers do not have to be removed. Brenspeed has gotten so good at doing nsr cams that charge $280 for labor. Unfortunately they don't do the FRPPs. If you are near them you might want to consider the new custom grind Comps though, they have a similar idle to mine.

BTW, I bought my cams at buyfordracing.com for $750 plus shipping. They have plenty of them.

I am a computer idiot, let's see how this works.

The second pull is actually to 6200, it just so happens that this is the part of the graph he printed, I guess you can't view the whole thing at once? As to why he didn't pull it any farther, I have no idea. Could have something to do with hm telling me that the rods in these motors don't like high RPM's.

Cam phaser limiters don't help torque, they take it away. Their purpose is to limit the amount of variable cam timing in order to prevent piston to valve clearance issues. FRPP does not recommend the use of either limiters or lockouts with the hot rod cams.
