Prollly asking for troubles. That said, if you have the OEM stone tray underneath, you'd have to be pretty unlucky for something to go through the belt / teeth.

In these circumstances, i always imagine what i would think if the worst case scenario occurred... I'd kick myself.

Id leave it on.

Asking for trouble mate. Anything that falls at the front of the motor will end up behind the harmonic balancer. If you leave it there it will destroy your timing belt and then engine. If you notice something falling there it is balancer off to retreive it.

They get left off because it either looks good, or because it makes it easier to adjust cam gears.

Either way its not a good idea

I cannot see any reason to leave the cover off unless you were having the car tuned on the dyno and needed to adjust the cam gears as part of the tune. After that I would always have a cover on. If it is a look thing that you are after they now make clear covers for RB26 and RB25 motors.

I have first hand experience with the type of problems that can occur with an open motor. I once dropped a 6 mm bolt down past the timing chain in a Mazda engine. After much effort we finally got it to fall all the way through and into the sump to allow me to retrieve it by removing the sump. This took TWO WHOLE DAYS to get the bolt out and an unbelieveable amount of frustration along the way.

      98 R34GTT 4k engine stumble

      By JC71 · Posted

      neither stumble or cut really seem to be an appropriate term....hard to explain its like a rev limiter but at 4k, but it violently shakes engine and entire vehicle as the rpms will not rise over 4k, even with slow acceleration. as soon as it hits 4k, it sounds like entire spark is lost entirely. plugs were 1.1 which I used as such, but later put in new plugs gapped down to .8 changed back after issue arose when I replaced the coils, still does it with either plug gap...damn and it was all running so good.

      Why am I hitting a power wall with my stroked RB25?

      Oh how times have changed! I actually lean it out relative to my water/methanol injector duty cycle. The methanol adds a lot of fueling and you can then lean it out even more due to reduced knock.

      Yeah my thoughts are the same, a well thought out WMI setup, would be slightly ahead of just straight E85 and you're also chemically intercooling the charged air, dropping it even further. This is why you need to add so much more fuel as soon as you spray. I remember someone taking me through their set up before (Dennis, has a R33, lives around Cabramatta - no idea if he's still around on this forum). He would target AFR 10:1 on 98, then as WMI ramped on, AFR would lean back up to 11:1. Amazingly, he did this all through his PowerFC, a relay to cut power to his EBC solenoid if there was not enough line pressure on his WMI kit. And of course, if there wasn't any boost made above gate pressure, you wouldn't be accessing the load cells with heaps of timing for WMI. One downside to that rudimentary setup, once the WMI came on, the EBC would unleash the dragon, and of course all the timing. Tyres would fry lol.

      They have said food will be limited. Mainly meat pies and sausage rolls from memory. But they have a coffee van!
