I know this can't be but ever since i changed to RP and added the k & N drop in filter my 0 to 60 times are slower by about 4 tenths. Now I know this is not logical, i believe the 8 hp gain from R P oil they tested it on Hot Rod tv, and the air filter seems believable for at least a couple, but this just can't be.

Maybe its the warmer weather, but if i don't hit my old record of 5.34 0 to 60 when it gets real cold out again, something is def. wrong.
Other than that the car runs strong.
anyone else have this mystery?

Gotta be the hot weather man...its finally cooling off in Chi-Town and I'm leaving patches through intersections (something i couldnt do a couple months ago in the dead of summer)...id be questioning that 8 hp gain too.

You need to get a programmer so you can run your fans cooler because I have the royal purple oil and now that I have my predator tuner my car runs so cool and my power is incredible.

You are supposed to gain 8hp by using RP? WTC, really?

Spittle how do i do that? does it make the fans go on all the time?
Did you really feel a big difference with the predator?
thanks.
Yes on a tv show they dynoed a engine with dino oil then drained it and dinoed it again with rp to see if there was any gains and there really was, so i believe it.
my car runs great but if i had extra dough i would get the
Predator, fan mod, afe stage 2 maybe the 180 thermo.

You didn't get the memo? It also makes your johnson about 4 inches longer.....

With less friction it frees up the ponies. Doesn't really "make" power.

I did the similar mods and am getting 0.2 0-60 better times. Not sure where your issue is. I have a SuperChips programmer. Try pulling the negative battery cable for 20 mins to reset everything. Who know's might help.

Either way, you should NOT be loosing any power....

I had done some research and that is why I invested in the royal purple oil. As far as the predator it is worth every penny and I had the superchips tuner and it is like night and day. With the predator you can adjust when you fans run and so far the highest temp I have seen is 205 and it used to be 225 and 230 before that and a lower temperature means more horsepower. I hope this info helped.
thanks,
