1st time at the 1/4 mile in the miata.
Went to the drag strip this afternoon for the first time in the Miata. Made about 4 runs in 6 hours. Had a few problems with the car, nothing serious so it was still a fun day.
All the runs were on low boost since the ebc wasn't cooperating with me. It was limited to the 5.8 psi wastegate spring, but it was still able to hit between 6 and 7. The setup is still the stock block with the SC61 turbo running on street tires. It would have been nice to have a bit more power, but it did fine for what it did have.
It was a good day and I am looking forward to spring. Can't think of a better way to spend the day prior to putting the car in the garage for the winter.
One of the guys from the shop has the run on video and I will post it tomorrow if he emails it to me.

Very nice. 2.154 60 and that 1/4 mile time, that's impressive. I ran 14.6 with a 2.577 60' running a T25 on 7psi with a stock clutch that wouldn't hold. In spring time I want my times to be pretty much close to where you are now. For my turbo though, it'll take a good clutch and probably about 12psi. What FMU / motor / turbo / clutch are you running?

My goal for next year is to make an 11.50 pass.

There's a few different versions of this turbo available, so this is just from Precision based on the engraved numbers of my particular turbo.
Right now I'm just running a stock block.

This is a little tricky, the original owner sold it to me as a ball bearing turbo and also specifically told me it was a ball bearing turbo. I trust him, so if it is different, then it's because the guy that he dealt with when he bought it new lied to him. On the other hand, Precision is telling me that it definitely isn't, but yet aren't 100% sure and can't seem to tell me anything else about the turbo. The more I deal with Precision, the less they impress me. I wouldn't really trust them to stand behind what they sell.
