Blow of valves consume more fuel?

I believe it does after I upgraded to an aftermarket blitz blow of valve, replacing the stock bov.

Your opinions?

And another question;

What is the difference between 95/98 octane fuel? Would running on lower octane, damage the engine?

Your car will use more fuel generally because it will be overfuelling.

You can either get an ECU, and have it tuned.

Or put the stock one back in there, nothing wrong with it.

You should run 98octane fuel in an import

It overfuels because the airflow meter reads a certain amount of air passing through it, a portion of which is then not actually entering the engine because the blow off valve allows it to exit the inlet tract.

As such, it thinks (and injects fuel as if) X amount of air has entered the engine, when in fact the engine only really has X - amount released by BOV.

Just a thought.

I've seen cars modded so the afm is moved to just in front of the throttle body, ie after the turbo.

I guess this would solve the problem of metered air being lost through the bov.

Has anyone here tried it on a skyline?

Seems like too much effort for some "chick pulling *NOT*" sound :)

      I'm actually not sure - I think it was "Stealth Performance" (It really is near impossible to find a FEMALE 1/8BSPT to 1/8NPT male at ALL) but having the thing leveraged on a 90 degree angle on a small aluminium fitting is not too smart. Also in not too smart, I've drilled out the center of the broken fitting so there's maybe 0.00001mm of thread to bite into, so yeah. I may have to get it drilled/tapped/plugged entirely. Given I could conceivably tap a thread/adapter/pressure line in any point in the oil system I suppose it's feasible to run a line to the Nissan Sensor to keep the dash working. Do these exist in AN fittings and the like? Like an AN fitting that has a NPT (or other?) thread as well for putting a sensor in?

      Anyone running the VQ37VHR with forced induction?

      I would agree.  There will be an amount of boost you could run safely with an otherwise factory system, but it would be low enough to not be worth the cost.  And if you are reliving your 20s, you know a 'little bit' was never enough. Personally, if I didn't want to spend the money, then stick with NA bolt-ons, and maybe a tune.

      Fuark, at least the motor survived. What brand was the fitting that snapped?

      Wrong question. There's no point in spending the rather large sum of cash and effort to add turbo, without taking it to the "sensible" limit of the motor itself. If you have to upgrade injectors, etc, then so be it. That is a tiny fraction of what it will cost you to turbo it.

      Measure voltage at the starter solenoid terminal when the key is at start and it has clicked. If it is really low, then the suspicion falls on the ignition switch (contacts or wiring thereof) as causing a voltage drop instead of sending enough volts to throw the solenoid all the way to engage the starter itself. If it is a decent voltage, then the suspicion is on the solenoid. Might have s horted coil, or might hva dirty contacts. Rip the starter off, dismantle, clean up contacts and inspect winding. It might not be possible to see if there is a short in the winding though. I have a spare starter here that I could measure the resistance of the coil, as a guide to about what it should be, if you need a comparison. <parts hoarder>No you cannot have it.</parts hoarder>
