What is your 1/8 mile ET/trap?


I average "Back to the Future" times 88 mph

The DA for these runs were -200 ft the Track sits at 90' above sea level
it warmed up a bit by noon so the DA dropped closer to sea level.

I always try to use S197 as my race number

FWIW, I've tried Mobil 1, Amsoil, RP and Valvoline Syntech. Out of that group, I felt the RP worked best in my vehicle and it is what I continue to use. I also use teir ATF and PS fluids.

What do you mean by "I felt" the RP worked best? Just curious. Noise?

butt dyno.. that's good. You must be from San Francisco.

Sorry for the subjective nature of my comments. What I meant was that the vehicle ran smoother, especially during acceleration and I saw about a 2 mpg improvement in economy.

I may try RedLine at some point as I used to use it in my motorcycle, but no one carries it here. I remain a fan of the RedLine SI-1 f.i. cleaner though.

This is what a guy at work told me as well when he put Royal Purple in his Cadillac.

I personally did not notice any change in Milage or operations of the engine, but then again it's been tuned to it's max potential so there would not be much room there anyway

I just read through this entire thread again. Royal Purple claims (I think) that their additive technology has a micro polishing effect. Maybe it's not just marketing?

It's all in the additives.

I`ll say this,when I ran the RP 20W50,my engine revved sooooooooo smooth and effortlessly that one night I remember I was trying to merge onto the interstate from a red light and I was spinning the rear wheels all the way into 4th gear trying to jump ahead of the pack. Is RP overkill,maybe,and only hard-core trackers/racers probably need it,but it`s definitely a GOOD oil! And when I was using it my engine`s internals through the oil fill hold looked like a mirror they were so clean. I have three cases of it,so I`ll save it for my middle of the summer heat oci`s.

Of course it's true. The only question is whether the broad performance claims are more true of Royal Purple than of any other good synthetic. wink

I know it has been a while since I posted the results, so a quick update on my experience with RP.

I pulled the heads to replace the springs with BeeHive's and did some light porting and polishing (clean up) I also replaced the Comp 127200 NSR's with the Parnelli Jones Comp 127300 VSR Cams. They have at highest lift without removing or limiting the phasers.

Here are some of the pictures( remember this car has 85,000 on the clock)


Porting and polishing





And yes, I did all the work myself...

I have 95,000 miles today so doing my Royal Purple oil change.
My friend's car, the one with the M1 Cams; He spun a bearing on the way back from Carlisle, PA; destroyed both heads, pistons and block as well as the cams. he is in the process of replacing the entire engine but the added cost of heads and cams is delaying the build.

I was able to test the Cams with a micrometer, I took them to the shop where his car is and had them MIC'ed the RP Cams with twice the milage had NO wear at all. We tested against new stock cams (shelf set from ford) and the Micrometer reveiled ZERO wear. yet the M1 cams had a noticable "groove" where the followers touched the lobes on the cam. I had pictures but traded my iPhone 3g for a 4G and forgot to pull the pictures. I will do this again over the winter, the Shop is doing a Dyno tune so I can take full advantage of the Cams.

Funny, a buddy of mine spun a bearing in his '01 GT a few years ago, I think it was #7 rod bearing. Though I think his was "user error" if you know what I mean wink

Car looks as awesome as ever thumbsup

Thanks,
My Friends car started to use oil, he ran low a couple times then "boom" I will try to find the pictures of the damage, it's bad. He was using Comp 127500 stage 3 cams with phaser lockouts so the valve lift was high, the valve to piston contact bent the intake valves and imbeded them into the heads. Sad, very sad.
