    Best Napa oil filter for GM crate engine for max power/torque?

    Thank you for this, this was exactly the info I was looking for. As stated above I went down a rabbit hole lol...again just an inquiring mind haha. So no matter the oil filter 10 mircron or 62 should not be a huge difference. Some of these dyno guys must be blowing smoke then lol.

    Best Napa oil filter for GM crate engine for max power/torque?

    I do not have an oil temp gauge in the car, thought about adding one. Many have run 10w-30 for the longest time but the newer engine seem that they the lifters like the thicker oil. Its getting plenty of air and never runs hotter than 190 on the hottest night. The oil is just not enough to pump...

    Best Napa oil filter for GM crate engine for max power/torque?

    The engine was flat and no longer pulled down through back stretch. Power rolled over...hit a peak and power rolled down. Swapped oil and it was back to normal and fast again.

    Best Napa oil filter for GM crate engine for max power/torque?

    I ran 10w-30 and as stated above the engine rolled over up top even with new springs. Back to 20w-50 and engine was best its been and top 5 in hot laps. So hard to go thinner with newer crates as lifters don't like it. What is your suggestion?

    Best Napa oil filter for GM crate engine for max power/torque?

    Why a XG5 over a napa? Yeah I can see too much pressure is a killer too. Had 10-30w but gm wanted 50w and with the 30w rolled over. They want thicker oil due to the lifters it seems. Hot at idle after a race is 35-40 psi. I haven't thought of a diesel oil but def know the thicker oil made it...

    Best Napa oil filter for GM crate engine for max power/torque?

    I do oil and filter every 5-6 races 35 laps each night. Yeah I've heard some have tested. I'd assume less microns is less restricted.....just a guess tho.

    Best Napa oil filter for GM crate engine for max power/torque?

    I have not dyno tested them or done any testing. Was looking for some insight first. Like a 41068 should it be used due to filter material? Which one is lestt restricted is what I was after to even see if there is a difference.

    Best Napa oil filter for GM crate engine for max power/torque?

    Ok so I have gone down a rabbit hole on GM crate 350 racing oil filters. I have crate in a dirt late model and have been running 51061R Wix racing filter with 20w-50. I'm looking for max hp and less of a restriction so would the gold or platinum be a better option? I see the 41068 has the...
