Hey Guys, I have been trying a ton of clutching approaches and nothing seems to be totally consistent. Just when I think the problem is solved, it happens again.
Right now my current setup is: 03 700 ves, 420 mains, stock needle position, slp single pipe, rkt head, 2 flowrites, slp big airhorn, 10-64, almond blue primary, stock secondary r12 and silver blue spring, 25/41 gearing.
Last year I only had the 10-64 and almond red primary and the sled felt the same. It doesn't really feel any fast at all this year. Don't get me wrong, this is no 500. It will still run 110-115 on the dreammeter and 100 on the gun, just looking for a few more.
The sled seems to be 50/50. Half of the time it will peg a long wfo run and stay right at 8000 rpm, the other half of the time it will peg 8000 and slowly drop to 7700-7800 the longer I hold the throttle. (key on premium) This is on a digatron egt. The stock factory tach doesn't seem to move from 8000, but it noticably falls on its face and you can tell the r's are dropping.
On another note, the sled seems to pull better when the temperature is cold, not suprisingly. Can the sled still be rich. The plugs look good at 420. I did several plug reads in the past few weeks when the temp was -10 - 25C. and the plugs were a nice light brown. At 15-20 below C I wouldn't even consider dropping the mains, however I wonder if I should drop to 410's when it is warm like -5C. Today it was only -7C There is also a ton of fuel in the airbox the warmer it is. My egts run about 1050-1070 at 50-70mph cruising, and about 1100-1120 at full throttle and doesn't seem to really change depending on outside temperature.
A couple of people suggested trying an almond primary (140/330) to try and keep the r's up. I also have a 38x helix and hot seat orange spring that I used and I thought worked, but didn't really pay too much attention.
If anyone has any suggestions please help.
thanks
