Took my first ride with my Turbo MPI trail kit. Did 216 miles and things worked great.

I have super tip clutch kit. I added 11 grams in the heel, two grams mid and 4 grams at the tip. Using stock spring in primary. The secondary is set at 3/3. The original clutch kit came from Ulmer racing.

It hits hard down low and pulls hard all the way to 85-90. Max RPM is 8,300 then falls to 7,800.
Any ideas?

Sounds like you have to much weight .
11 grams in the heel ? That's a lot. How much are your weights currently weighing?
I would put 3 grams in heel and zero in the mid and keep 4 in tip.
 
I have the Ulmer/MPI clutch kit and if I remember right I have 3 washers in the top and 3 in the bottom none in the middle. I have a 16xtx trail turbo and don't have the issues you have stated.

Is this a kit for a stocker that your trying to use with the Turbo?

I have the Ulmer Clutch kit. I emailed him and he gave me the current weight set up. The clutch was machined and set up by Ulmer for my Viper when it had the can,tuner and intake. I have emailed him again, but was hoping to get feed back from guys that have the set up.

What top speed are you seeing and top RPMs?
 
You will most likely need a different helix and secondary spring now with the turbo
 
The helix and secondary spring are the same. Just wondering if anyone knows the base weight of the cam arms. The ones I have are 50 grams. Wondering what the turbo base weight is that comes with the turbo clutch kit is?

The base weight with the tubro is 60g. but you should be able to make the 50g work.
 
It sounds like he had the 50g SuperTips before he was turbo'd. With his current setup hes at 67g.

How old are your springs Swamp?

The springs have about 6000 miles on them. I am guessing I have to much weight. I think I will remove the 2g from the middle and 2g from the tip.
 
I would get new springs in there to start. Then I'd pull 1 from each location and see what it does.
 
Turbo set up with ulmer kit that we have
Perimary and secondary spring that Allen supplied and Helix K
60g weights
3 washers +o-ring in heel
None in middle
2 washers+o-ring in tip

Great, Thanks this is what I was looking for. Do you know what colour springs you have? What turbo kit do you have?
