I did a couple of runs on the egv plugs and they seemed fine, took them out to put the br10eix and they seemed to hold up pretty well

Most of the rotary guys I know run .020"...that is what I run also....idk what others are running.

Chris

I've never gapped my plugs

mines are the ngk platinum 10 eix

get them from napa around $30 bucks

I guessed at .030", but your reply made me realise what i'd done wrong :icon_tdow

I'd grabbed the wrong feeler gauges as I was rushing and have gone and gapped them at .30mm, ie 0.01", what a 'tard! :lol::icon_tdow

Cheers for the reply, info here I could never get easily in England, really appreciate it.
Will do it again properly when I get in tonight...

can you post your results after you gapped it

been running greddys for a little while now ....got rid of my breakups and shit ......throttle responce seems kind of crisper too .....not bad at all

where are you guys sourcing these greddy plugs from?

I just googled. Somewhere i posted the greddy part number to look for. You can also look for prorotary greddy plugs. They are listed in several places like that.

Done, and just taken it out for an hour, a mix of busy town driving and hard to the rev limit acceleration.

Gapped to 0.020" and without doing anything else (to try and de-flood it etc) it started immediately.

Idle sounded (and smelt) more woofley, like it was rich, even though I changed nothing but the plugs.

Once driving, its deffo more responsive and punchy with these plugs, and pulls better at high revs without doubt, what I thought was the rev limiter before was deffo a missfire just before the limiter, and thats now gone. Under hard load, they deffo cope better.

Massive flames on the overrun now, which says to me they arent as efficient when not under load. The guy in the Aston Martin DB7 who tried to race caught a huge flame as I went past him though.

Now and again when putting the clutch down from high revs to stop suddenly at the lights etc it tried to stall, maybe only 1 in 10 times, only caught me out once, but it started again ok. Certainly didnt do that on the stock plugs.

Overall, id say a good improvment, the occasional stalling is a bit shit, but id partly put that down to the cars poor idle control, and on track it wouldnt be an issue anyhow.

Time will tell how long they last.

Hope this helps :)

the only decent place i know that has the greddy plugs are horsepowerfreaks

went ahead and bought the greddy pro iridum 11 race plugs for $120 shipped. cool guy and thats the lowest youll find for them!

I found them for 116 shipped but yeah it's hard to find them for that low.

/\ and hes right up the street. I think these greddy race plugs are better than the ngk just because the greddy are made for a rotary engine rather than the ngk being a universal spark plug

tell them james sent you ($120 shipped for the greddy 11 heat range race plugs)

Update-

Did around 1000km on the B10EGV no problem, then accidently flooded the engine. Dried them out and got the engine going again, but now missfires sometimes at around 6.5k, especially with the water injection switched on (ive got it rigged to a switch rather than just ign on, so can test stuff easier), presumably this is peak torque, as its fine afterwards all the way to 8k.

They are cheap and worked well till then, so will get some more and see how long they last as I think it was the flood that ruined them...
