Stuck On Wot

[3LGODZILA]

The other night i was giving the GTR full throttle and when i backed off it just stuck there bouncing off the limiter . My pedal was not stuck, this was the first thing i checked before shutting the engine off. When i restarted it was fine, it was going ok so i gave it 80% throttle still fine, so i tried full throttle again and it stuck again.

now i had a look under the bonnet, butterfly linkages move freely fine, however the very last butterfly near the firewall had a plug from the wiring loom rubbing against it, now i THINK that this was causing the issue because ive since moved it away and it may have fixed the problem but ive only given it full throttle a couple times since and it hasn't stuck.

the motor is built but the only part unknown is the oil pump, which makes me not wanna risk this problem happening again, any input or theory is welcome.

what i cant understand is when i shut the engine off and on again it was no longer stuck, if the electrical plug was wedged up against the butterfly jamming it from springing back i cant see how it would free up after turning the engine off and on again. for now im gonna spray up all the moving parts i can see without ripping things off with some CRC.

when you shut off the engine from hitting the limiter, the engine will rock violently. this is probably just releasing itself from the plug it keeps getting caught on

^^ It does? you got pre-ignition, torn engine mounts or something equally as stupid going on.

op.. seems you have fixed your own problem.

abit of exageration, but it will rock enough to loosen itself surely.

I hit the limiter all the time with my N1 pump!

But ye, it'll be that piece of loom by the sound of it.

I had it happen with a stray hose on my RB25 years ago, no idea how the hose even got loose/into where it did. Mysteries

im hoping its just that its farken scary !

other possibility is the motor moving during cranking shaking it loose

Good to see you got your GTR at last.
