angle of rx1 helix? does it work well with stock srx?


it will make you over rev some.Good note: on a warmer day(above 0C for example) it keeps the rpm decent,on a cold day it will over rev.Usually you run a w-w-w primary spring with that helix.Usually wrap to 70 with a green spring.
On a 7 C day here one Winter(in April) I ran with it on a River with just ice,no studs and my speedo climbed to about 118.5.I did it seven times over and over with same results.
 
The rx1 helix is a 51/43. Check the tech pages there are some combos using it in an srx. My sled didn't perform well with one but I have a lot of other aftermarket parts that contributed to that. Your mileage may vary.
