Ok here is the deal. With odonell 30% (regular) in my ws7 I could get 11:00 easily and that's with a 7.5 insert in my rc8t odo 97t plug. Last night I could barely get 7 min when I ran the new 30% speed blend. It also went from 220 to 244-273 in temps. Is my tune off maybe. I also had to open the idle gap 6 hours.

I opened the idle gap and it stopped the cutting off at idle. I was always told with a proper tune u shouldn't have to touch the idle. Does anyone have a good base setup for the new fuel.

Given your reduction in run time I'd say it's too rich now as well.
Perhaps leaning out the low end will help your idle too.
I run RB #7 plugs.

I'm not sure on my exact needle settings but I just switched to the new 30% on my WS9 and had to lean out the low end and the top end quite a bit, I think it was close to 12 hours on both, sorry I can't be more precise.

I gave up with monitoring the temp on this engine, just made sure there was always a little bit of smoke. Maybe a colder plug is worth a try though if you're really worried about the temp but it will make the tuning and the idle harder to get right obviously.

You shoul dnot have to open your idle gap that much to make the engine stay running. The idle gap determines how much air the engine gets and that should always be close. Close your idle gap back to where it always was and lean the LSN to get the idle stable. From what I have heard from others running that fuel, you will also have to lean the HSN as well. Everyone I have seen post about that fuel gets better fuel mileage with the speed blend when compared to the old fuel so your tune has to be way off.

First of all I'm sorry for my english mistakes,I'm from Brazil and only have 15,so give me a break.
Anyway,I have D8 with a RB hobby9, I only ran it two gallons.But last week I completely forgot to chek if my airfilter was decently oiled.The result,dirt in my engine and two burned glowplugs.So I got home and opened my engine cleaned everything the best way I could with my byron gen2.I don't have that much experience(neither my father) so I came here to ask what more could I do?And is the 'life' of my engine to compromised?
Final observations:I ran two or three tanks whith it that day.
Any help or coment will be very helpfull.
PS:If is a page talking about this sorry for not finding it,there are a lot of great stuffs in this forum,however is really hard to find.

It's possible that the engine will be ok but it's hard to tell. If it ingested enough dirt to kill 2 plugs it was probably quite a bit of dirt. After you clean it all real good, hold the case to your ear while turning the bearings... If it sounds crunchy that's bad!! Also look at the piston and sleeve for some obvious scratches.
Last thing you can try is to just run it again and see if it will run. If you cleaned it real good and it still wants to die all the time it is probably done. Good luck man!!

Do any of you use cheaper bashing/ practice engines and swap out for race?
I've realised how many gallons I've gone through on the WS9 already and am wondering if I'm better off race tuning the expensive engine and using a basher for the other mileage.
I love throwing cash at these cars of course but to keep costs down and make it easy it would be great to leave the pipe combo as is.
Any thoughts?

I like to keep several practice engines around. What I do is just rebuild an old engine and use those for practice engines.
