ok im just posting this to see if anyone else has run into this problem. I have been getting a lot of opinions and its starting to just confuse me.
Whats happening is everything is running good until i reach full boost for more than 1-2 seconds it dies out and almost puts me over the handlebars. The engine doesnt stall, it just cuts out then comes back after a couple of seconds.
Here are some details:
Twisted turbo race gas kit
3076 Bigger turbo
Boost-it control box
Twisted turbo m1000 testing - YouTube (this is how its running. fine when i don't hit full boost for more than a second)
Boost: About 11# from what i gathered running C111 and Avgas mix 50/50
-Now i have had a couple different opinions on this, that this 50/50 mix isnt a high enough octane for 11# give or take, and that i should be running C111 straight. Ive also told the 50/50 mix should be fine. However, i was tickling detonation as my plugs came very loose on me even though my A/F ratio gauge was reading rich at 11.4 when 11.8-12.2 is recommended.
So then we figured perhaps fuel pressure. But i tested it last night after checking my pistons and rings to see no signs of damage luckily and that the fuel pressure was going up as required to as high as 50-52psi (+1 psi per # of boost) with 10-12# boost spiking. (no load so hard to be accurate but its coming up so crisis averted)
I have also been trying to turn down the boost with the boost controller but this thing is tricky and ive had two different opinions on how it works. Trying to turn it down to at least eliminate too high of boost for octane levels and go from there.
I have also been told perhaps its electrical. Neil and Shain that build these kits both figured it wasnt because it runs perfect until i hit peak power then shuts down. But anything is possible so im trying one thing at a time.
I talked to neil and i am going to try and give it some more fuel on the top end as well from 7200-9000rpm as a few other guys think it might be leaning out at full boost and thats why its tickling detonation.
ANY information or feedback would be much appreciated in this dilemma. I think im going to give linderman a call today to get one more opinion and then go do some more testing. Thanks in advance!
Just called Linderman, he figures leaning out on the top too, otherwise he is stumped as well.
