I had a few exhaust leaks so I pulled the hotside off the car and replaced the junk fel-pro gaskets.
Still fighting a driveline vibration after adjusting the pinion angle but it seems to be getting better.
Here's a cold start idle video from tonight

Sounds great man! Love where the turbo sits with that kit. Where are you getting the vibration? Is it rpm related or speed related? I had all the top suspension sponsors on here telling me they were 99.9% sure I had a pinion angle issue. I spent hours and hours screwing with pinion angle. Finally replaced the worn out 10 bolt and it turned out to be a worn/broke part in the rear causing the vibration. New s60 and ZERO vibration!
Subscribing to this one.. Thanks for the link in that other post. There's a lot of stuff here that I'm not knowledgeable on, sensors, etc.. So I may have some questions at some point. Car looks awesome.. Mine is a white SS, same kit, but with 5" downpipe and ceramic coated. 408" with a S484 race cover with 1.58AR housing.

I was able to get the car on the dyno last month and make some pulls. Spark issues ended the session early but I was happy with it.
Pretty amazing that we caught the arcing on video:

I've put almost 1300 miles on the car this summer
It maxed the twin 255's around 11lbs so I installed some twin Walbro 450s and turned the base pressure up to 58 lbs. Also programmed the 0411 pcm to work with the newer plastic tank (using the 99+ sender) and 98 gauge cluster.

Nice job! Engine compartment looks great!
What kind of power does it make now?
On your vibration, it looks like your front yoke is slid out pretty far from the trans, that can cause vibration for sure.

Looking awesome Ray!

The vibration was two loose panhard bar bolts...one of them didn't even have a nut on the back side lol.

Catch can routing: I'll PM you some pictures!
Map sensor: The map sensor currently installed is from DSX tuning but he no longer makes them. I've used this sensor before with great results: http://www.efisource.com/shop/ls1-st...ar-map-sensor/
You're welcome!

Ray, great work. Beautiful car, beautiful build.
As I am currently in the final stages of my turbo build for my LT1, I keep worrying about heat and what it may damage. I can't help but wonder why you are running the downpipe so close to the cold side going into the TB all while not running any exhaust wrap on the downpipe. You don't seem to be having any issues with it, but I would think that the un-wrapped downpipe would heat up that cold side pipe quite a bit and your IAT's going into the engine.

After some hard runs (130+ mph full boost stuff) I can pop the hood and hold my hand on the intake pipe no problem. It doesn't skew iats or really get any hotter then rest of the cold side piping. The pipes are about .5" away from each other at the closest point.

5"? It looks like the two are practically touching each other where the downpipe turns 90 degrees down and the cold side turns 90 degrees to the straight into the TB.
