Looks like you get better times with the 17% pully. This is a great test for daily usable power (overtaking etc). so would you say the 17% is better for day to day use?
Interesting you see gains in torque down low too. There is the old saying that BHP sells cars and torque wins races.
How are the IAT? I know it was an issue with the 17% on your dyno, but that cant replicate real world air flow. Would be interesting to see what your car is doing now on the road while testing. I would like to see what timing is doing as well as IAT, as the Eaton should be outside of its comfort zone for RPM and heat.
Great to see people giving this a try. Soon as I get the boost leak fixed I'm going to get this done, hopefully with someone helping that has a decent data logger.
I believe the best we had over the last couple of days is 229 with the 15% and 224 with the 17%.
Now the funny thing is that every 17% car we had on the car before hasn't made horsepower but the last couple of days has seen some intresting results.
Immeditley the weather has been supercharger weather the last couple of days.

Yes stock but with a Janspeed 4-1 no air filter and a Cooper Borla Exhaust.
Yes I think for the 30-70 the 17% showed a good gain, obviously us being competitive like we are we'll keep refining the engine to keep improving the ET there' s loads more parts to test and I know I could go in the 5.3s but 4s have got to be the ultimate goal
Unfortunatley our program has failed us the last couple of days so no iat timining data is available, but we did try a 17% car the last week in similar conditions and saw 59 deg IAT If i had my hand held weather staion with me I 'm sure the 14 deg amb would of been 4 deg.
There's a lot more testing to do and I do like this concept but I might take this another step further by comparing 30-70 in 3rd and 2800 - 6800 as well, I believe where you'll gain with one you'll loose with the other.
But we'll see.

I'd be intrested to see the same tests done in the height of summer, or after the car has been sat in traffic for an hour letting all that heat soak into the intercooler
You will not run a better 30-70 or 1/4 mile time with the weather as it is now.
We've removed the nitrous for the winter as we're doing a lot of testing with oem parts, I've always been a person who likes to achieve more with less and believe our customers should bemefit the same way by spending less but acheiving real world horsepower.
As an example I know people who are making between 220-240whp 250-270bhp with stock cat backs and stock air filters.
We are not salesman just horsepower junkies.
