rTook my car to hidden vally drag strip on friday night.

Did a best of 15.343 @ 90mph/ weather was 32dec and 98% humidity/

car is running a catback exhaust and pod and is auto.

just wondering if this is the time i should be looking at or should i be going faster?

how are your launching the auto? i wont recommending doing it too often as it will causing premature failure of the gearbox if done too much, but u should try stalling it up (hold the brakes and hit the rpm up to about 3000) just b4 take off.

First run was just stomp on the gas did a 16.1 for that

2nd got it up to 5000rpm in 'n' and droped it (Still had tyer pressure at 36 psi= wheel spin 1st 1/2 way in 2nd)

3rd was at 4000rpm tyers at 30psi and she did a 15.3

from there on i just played with the revs.

I would rather not do the way mentiond as i managed to blow my r31 auto box like that after 15 runs.

yeah that is probably worse then i mentioned. next time as the lights start from the top of the tree, have it in D, hold the brake and hit the gas to bring it to say 4000rpm (play with it to get good launches) then release the brake and hit full throttle.

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.

      ..this is the current state of that port. I appreciate the info help (and the link to the Earls thing @Duncan). Though going by that it seems like 1/4 then BSP'ing it and using a bush may work. I don't know where I'd be remote mounting the pressure sender... to... exactly. I assume the idea here is that any vibration is taken up by the semiflexible/flexible hose itself instead of it leveraging against the block directly. I want to believe a stronger, steel bush/adapter would work, but I don't know if that is engineeringly sound or just wishful thinking given the stupendous implications of a leak/failure in this spot. What are the real world risks of dissimilar metals here? It's a 6061 Aluminum block, and I'm talking brass or steel or SS adapters/things.

      And if you have to drill the oil block, then just drill it for 1/4" and tap it BSP and get a 1/8 to 1/4 BSP bush. The Nissan sender will go straight in and the bush will suit the newly tapped hole. And it will be real strong, to boot.

      No it doesn't. It just needs an ezy-out to pull that broken bit of alloy out of the hole and presto chango - it will be back to being a 1/8" hole tapped NPT. as per @MBS206 recco. That would be for making what you had in alloy, in steel. If you wanted to do just that instead of remote mounting like @Duncan and I have been pushing. A steel fitting would be unbreakable (compared to that tragically skinny little alloy adapter). But remote mounting would almost certainly be 10x better. Small engineering shops abound all over the place. A lathe and 10 minutes of time = 2x six packs.
