I put an ECP kit on this year and want a good clutch set up to utilize the intake upgrade. My sled is a shorty with ECP kit 125" ripsaw and 168 pics.
What do you think?

Matt,

Back when you had the Speedshop, I purchased the Supertunner Stage II kit that came with HH setup and 52/44 helix you mention to go along with the ECP filter kit I had on my 03 RX-1. I've been more than satisfied with the setup but now find myself needing to replace the helix. Most of the places I've searched offer the 52-44 as a custom job with the exception of Dalton Industries but Mountain Performance had it listed as an available helix and was cheaper than Dalton. However, when contacted, they only had a 53-43. My question is should I stick with the 52-44 or would the difference between it and the 53-43 be minimal? I've since extended the Expert X to 136" and re-geared to 23 top and 40 bottom. Any insight you could provide would be greatly appreciated. ;)!

Thanks,
Rob.
