have running mine with 1/2L 5% and 1L O'D 20%, then turn it to race run, compare to Spec II the XZ had more bottom power and great top speed , i ran it about 95 to 100F and with a RP6 plug, OS t-1050 pipe, will try RP7 plug next time.

I ran it on State Title with stock plug (RP6) and T-1050. Heaps of bottom end power compare with Speed-I and Speed-II. Especially with T-1050, it makes the XZ sing! But so bloody thirsty!!!

yep, the temp i ran with have had arround 5m15s run time so next time i will test if RP7 can help a little more.

what restrictor do you use? I seem to be able to get more than 6 min all the time using RP6 and 1050

20% or 30%?
Does this engine come shimmed for 20 or 30%? If I run 20% does that help with run time?
Thanks
