BIR went good. I learned more about setup, due to changes made over the winter. I'm still having issues getting it off of the line. I was changing boost levels that I launch with and the result was that I either over power the tires or bog the car. With the AEM series 2 EMS I have a way to make this easier. I will be tuning the launch at the MAP event in June.
This video I spun off of the line. I wanted to see the parachute opening.
I went there focusing on tuning my 60 foot times. It's been difficult lately since I either blow the tires off the car or bog the car resulting in making it hop. I'm working on staging power in slowly in first gear for a smooth/quicker launch.
I launch my first time only expecting to go 60 feet but the car seemed like it had made it a good 60 time, but hopped bad 2-3 times, i ended up running it out to a 8.85 @171.
I ran about 3 or 4 more 60-foot passes and put it away for the evening on Friday. Start the car up and Saturday and noticed noise coming from the alternator. Also the coolant system was pressurized, so another leaking head gasket. I enjoyed the rest of the weekend as a spectator and provided some help two other racers.
I'm going to toss another gasket on it for the next event, and over the winter focus on getting an O-ring block and receiver groove in the head to use a copper gasket. I should have probably done this last year as I found the limit on the MLS permatorque. I've learned some good information from others using copper gasket setups with great results.
See everyone next time!

I would say copper and ring is the way to go for big boost for sure. That's a really solid pass and impressive trap. Seems like your car has plenty of potential to meet your goal.
I have had good luck with a o-ringed block and a 3 layer cometic head gasket, .050" SS wire sticking up .008"-.010". I have thought about limiting power in 1st also, keep after it we will get our short tracks sorted one of these days.

Time for those winter projects! I've got a lot of plans for the car this winter. Want to freshen up a motor, new turbo, fabricate a 25.5 cage, get some carbon/kevlar doors, fenders, roof, hood, bumper, dash?
I just took the cage out of the car today. So here's the starting point to the winter journey!
With all the dsm guys getting into the sevens I might as well try too!
Starting point:

PG2 was good, for the exception that I blew another head gasket. While freshening up the engine this winter I'm going to move to a copper head gasket setup with orings in the head & block.
This was one of my 8 second passes from PG2. I bogged 2nd pretty bad, but cut a 1.3 60ft. I'm going to reduce power next year off the line so it will hook better, by regarding timing just for the launch in 1st gear.
Awesome man, can't wait to see what it does next year
Thanks guys!
I can't wait to use my welding and Fabrication experience to make my new cage. The old cage suck so bad it was one of those prefab units and I had very limited experience with TIG welding. It should turn out pretty good! And I'll feel much safer going over 175 next year.

I am excited to see how this turns out! Probably felt good to cut the cage out if u didn't like how it fit and having some nice consistent welds will give you some peace of mind for sure. You really are tackling a huge project here this winter with all this. What are your plans on motor and turbo, I believe u have a 2.2 long rod right? Who makes all the carbon Kevlar parts?

Thanks for the comments. Yeah its a huge project, I think the biggest one I've taken on over the winter.
I'm excited to build the cage the way I want. I purchased a much better tubing notcher, from rouge fabrication, this will help the tube fitment consistancy. Its a large shopping list of 4130 tubing!
I sold my pte7675 Gen 2 turbo and bought a pte 7685 Gen2. I'm running a 2.2 long rod now, I'm moving to a 2.0 long rod for more RPM, with a copper head gasket. The added rpm in 1st and 2nd gear will help bring down my short track time. I'll be able to run more boost, resulting in more mph & beter e.t. I'm stil going to run e98 this season too.

I'll dig it up and get a photo posted.
