ah yes i remember that thread..... I even think i had a post in it asking about the 847 cam right before i installed it.

 

Read your sig. Spun rod bearing, NO WAY. As in some get lucky and some don't. Sorry for your misfortune.
Are you listening, taubr unit?

 

I don't know about anyboidy else on here, but the "years" I spent researching my setup and figuring out the right oiling system to use. I noticed that most guys that spun bearings after big cam installs didn't upgrade the oiling system and where using 10-W30 also. Has anyone on here that spun a bearing upgrading thier oil system?

 

what would you suggest as far as upgrading your oil system? i also just got the 847 put in my car..and it will be back soon. i had them install a hv oil pump since i needed a new oil pan gasket. what type of oil would you recommend?

 

ooh ooh ooh (have my hand raised like a unpatient school boy looking to answer the question) lol

I replaced the pump, upgraded to the "white" spring and always ran the larger truck filter with Mobil 1 5W-30

 

Did you have them install a larger pan with that oil pump so you don't suck your pan dry of oil?

 

im listning to everything said. And you are right, some are lucky and some are not. I know im rollin the dice here, but im goin with my car was not beat and will hold up. Im not at the track everyday and only drive it a few times a month. I know it only takes one time but i guess il see. Right now im getting my valvetrain set-up for it so that doesnt take a shiit on me when i rev it. But now i got all that set up right so time to put back on the timing cover and finish it up.

 

Don't mind me giving you a little crap, I'm just trying to look out for you. Maybe try some 10-30 Royal Purple in it, it seemed to help my oil pressure by a couple of pounds, and I've heard good things about it.

 

When my engine was done my engine builder suggested to use 15-40 for the first 1000 miles and then use 10-40 or 20-50. I asked him why to use the 15-40 and he told me he knew that the guys around this area are hard on cars, and thats the reason for the oil I didn't argue and did what he suggested and I was spinning 6500-6600 to my shift points with no problems yet. Also have a 10% over stock melling oil pump if it matters at all with the stock pan. But when I get my tubular K I'm going with a 7 quart moroso pan and a high volume pump

 

this whole project is turning out to be a pain in mt ****. Had to replace the oil pan gasket cause i screwed it up taking out the taiming cover. So $30 nd a few hours later im back on track. I knew from the get-go i should have pulled the motor and did it all on a nice engine stand! Oh well, hopefully in the next few days ill be done. And i plan on running some real good oil and a bit thicker for the upper R's ill be spinning.

 

Sounds like too Hightech a question for me to answer, but what I did was go with the white spring,and I sent the HV pump and pan I had back and decided to keep the stock pump. I took the cash and hooked up an accumulator kit, now the oil pressure is always cool. I run thicker oil 10w50. so far so good. I remember reading post about people running the pans dry with the HV kits, and about oil starvation at higher rpm loads. THe guys that starved the motor spun high and didn't upgrade the oil systems, and the guys that ran the pans dry where cases of wrong combinations. Like stock pans hv pumps...etc etc. Just trends I noticed on these forums over the years.

 

i've been considering the 847 but with 1.6 RR's it's like .060" from coil bind on the 918's if i remember right. would that be a problem at 7k?

**EDIT** i did the math again and the 918's bind at .600" lift and with 1.6 RR's the 847 lifts .5952" on the exhaust. is this not a problem?

never mind i just realized they bind at .700"

 

you guys think i should upgrade to 30lb injectors while im here?

 

Springs don't coilbind at a set lift on all applications, the 918's coilbind at 1.085", so take your installed height and subtract it by 1.085", then subract that by .060", and you get your max safe lift without coilbinding them.

 

I guess I am the exception. Cam only 847 spun to 7k for 2 years. I just freshened it up becuse the stock oil pump pick-up fell off. That has been the only thing to give out. Bearings looked fine.

Car goes 11.80-12.00 pretty consistantly.
