Anyone know the answers?
1. What is the SRT6 stock pulley size? I see 178s, 181s, and 185s are available.
2. What is the SRT6 stock level of boost? Looks like the pulleys above produce 14%, 16%, and 20% respectively.
3. What other mods are needed with the 181s and 185s (larger HE, belt, etc.)?
4. Why do birds suddenly appear . . . . 
Thanks in advance.
1. 6.125" or 155mm
2. 14.5 PSI
3. The 181mm will require nothing, but a good tune is helpful, the 185mm will require a larger heat exchanger and possibly a tune.
4. Because of the stuff you smoke.
