    I first of all want to thank Ben at Turbo dynamics. My friend Tom has had his 2017 sidewinder ltx le with a tune by TD run consistent 135+ to 141mph in 1320. So I decided to tune my new srx with TD.
    I have the max spool 17 in the sled and run 94 octane only(no octane booster) and currently and I ran 128mph on ice in 1320 but the clutching was off. Rpm's were around 8450, so I pulled all the weights out of the dtya1's on sunday and ran them empty(they measured 75g on the scale). Now the sled runs 8800 right off the bat and climbs to 9150rpm's in 1320 and holds there. The max spool 17 showed me 18.2lbs of boost.

    Now let's get back to today runs. It's really warm here today 7c and I wanted to see what the sled would do in 1320 and 1500ft. I ran it back to back for 10mins straight on hardpack. The sled no issues with the belt and I made sure to run in the powder after every run to keep it cool.

    I saw 138-139mph's on the speedo in 1320 and 142 mph's top speed in 1500ft. The speedo is out about 4-5mph, but the gps is right on! I had the 1320's speed on the gps but I didn't screen shot it properly at 134mph.
    I did get it right with the 1500ft pull at 137.2mph.

    It's working well IMHO anyways with all the hard work Ben and the guys put into testing. The best part of all is, this is my trail tune. Wait til we crank it up!

    Sorry I had to revise my rpm's on page 2. They were a little higher(9699rpm) than I thought, so I posted them here as well.

    Interesting. I'm running MS17, 3"Viney, 3 bar, and CAI with DTYA-1s with 5/8 and 3/8 added. I've only done a few short passes in the field so far but it hit the rev limiter hard on one so I added The 1/2 for now. Can't wait to actually get it on the trails. Anti lag starts on frozen ground is a lot of fun for the couple seconds I can hold it before running out of room. No clue how fast I got it. No time to look down before having to slow it down in a hurry. My neighbor that used to have an old camaro that ran in the 8s in the 1/4 took a pass and just shook his head and laughed at how fast it is.

    I plan on running the same tune, and these are the weights I'm using, so thanks for this info. Maybe a bit of weight needs to go back in, as I'm shooting for 8800-9000

    try them empty first, then start with a 1/4 and up from there.

    Nice speeds! The secondary is still the 35/39 SRX helix with the pink SRX secondary spring?

    Nice work!

    Those speeds seem high though for 22/41 gearing.

    Wishful thinking. Maybe if you dropped it off a cliff?
