who runs a dash mounted op warning "light"?...

[BDSax]

I have an AIM Mychron3 I'm setting up over the offseason

lol, i use the same tach for go kart racing

[nando]

yeah, it varies a bit depending on temp, but that's usually what I'm seeing. right now it's probably too cold for 20w50, but I have to go to canada if I want something like 5w50..

[JRKOUPE]

cold idle is like 50psi
warm idle is ~14psi
full load 60psi
normal driving - 20-60psi

oil temps will run 160-180 normal driving, over 200 on a hot track.

with 20w50 Mobile 1

Im about the same...w/m20...20/50 gtx.

...really cold Im over 50 tho....over 60 too.

on a hot rockin track day.......Im a wee bit over 200 degrees.

Ben....for 24v's...try bimmerforums.com...track section

this is M20 right? I'm guessing M5X/S5X is pretty similar.

yeah, M20

AFAIK M20 and M50 bearing clearances are the same (at least, the part #s are all the same), so aside from differences in the pumps and oil used they should be similar.

Ben, my M42 does similar pressures with Castrol 10W-40

The longacre light looks nice. The autometer sport comp II is nice too, but may be difficult to see & are $199.

Not to hijack, but people that have oil pressure and temp gauges, what are you typical seeing at cold idle, warm idle, regular driving, etc?

[JRKOUPE]

7psi for idiot light, jrk asks a valid question, i 've seen race cars using the sun type ones. longacre has one too. i'll probably install the longacre one in the racecar. btw, jrk, have you seen the new baffled sump i'm planning to install?

show me pics.....

ya know i run one?....it works!!!

[e30guydownunder]

I have an AIM Mychron3 I'm setting up over the offseason, with adjustable alarms. I'm not sure what number I will pick yet, but probably just below whatever it idles at, so the light isn't on all the time.

The dash only has a little warning LED, but I'm planning to put something like a trailer lamp next to the dash for my oil pressure, or any other important alarms (ones worth shutting down for) for that matter. And to clarify I have gotten rid of the factory cluster, just have the AIM, boost guage and warning lights in that area, along with a few other guages in the cabin.

I'll be using one of the Autometer bullet style mounts with a sender in the high teens, hopefully.
This light can be hose clamped to the steering column shroud or fixed by a couple of short screws.

Could just get a Oil pressure gauge with warning.

hard to see while racing. typically looking out and ahead. checking gauges on straights only, by then it maybe too late.

I've been doing a bit of research on "op". OEM sensor is claimed to be 7.5 PSI new. I bet it wears out wears out as it ages. It a ball and spring arrangement.
