Surging Randomly

Recommended Posts

Hey all, over the last few months in the cold I felt the car surging when WOT in 3/4th gear and afr was around 12-12.5. Now regardless of the weather it’s doing it. Cars making 440 RWKW on the hub with a walbro 460 intank pump no surge tank. I did have a issue a awhile ago were the car was breaking down up top but found it was blowing the spark out cause the spark plug gap was to big, so we re gapped the plug and that fixed that issue but this time around it doesn’t feel like it did before at all because before the aft was never that high. so I’m convinced it’s not that issue. Have not pulled the plugs out again to check them though.

440rwkw on a single 460 intank without wiring upgrades is pushing the friendship a bit, Buzz in a new Petrol filter ( Genuine turbo ford ) re gapped plugs aren’t a brilliant idea. Grab some new YE07’s from Ford and see how it goes

 

Honestly I would be having it on the Dyno in itself current state to ascertain the exact issue first but I understand not everyone can access a Dyno for troubleshooting

I have done the Wiring upgrade, I put a brand new fuel filter in when it got tuned last year, do you think I should still get another one ? yeah I was going to take it to my tuner and take a look but im putting a new turbo and surge tank on in the coming months so not really going to bother taking it now. was just hoping it might have been something small I can sort out in the mean time.

When first converting from 98 to E85 you gotta change/clean your filter regularly for the first 2000 Kay's or so. As that unit is serviceable I'd be ripping it straight out and giving it a clean.


Easy job, other then E85 smells terrible on your hands/arms.

Alright will do thanks heaps man. I have seen some post's about people using a 10 micron over the 40. Is it worth a change to a 10 or is the 40 okay.

Ahh can of worms there lol. Stock is 40 I believe. Yet aftermarket injectors often call for a 10.

Personally been running Ryco373's for nearly 7 years on the same injectors without issues
