When what was really wrong is the oring was bad. No worries found a new one for $100 online. So all fixed now.
Thanks.

Heres my mates R33 GTR with an RB30/26 motor with an 8374 1.05 rear. Car is an absolute monster to drive. Boost is currently capped as the road rage gauge didnt work so no idea of shaft speeds. Most a car has done on this dyno with an 8374 is 480kw here in Straya 😉

That's very unfortunate! However, the upside is the car did not go up in flames, so there is that

P.S September is only a few weeks away so mind you!

Still the same Evo 9 with 2.4 and R2 cams.
This is the 9174 thats been on the car for over a year now. Look at that power under the graph! And holding 750hp for nearly 2500rpm. This was 39psi spike

tapering to 37psi.

Update! We got my car sealed up and running, but it had a weird miss at idle. Turns out the belt tensioner went bad and the timing jumped a couple teeth. Good news is no damage and a tune is going to happen the next weekend my tuner is free.

Bonus Pic: My complete Origin Fabrication downpipe + testpipe. 6.2 pounds!!

Glad you found the belt tensioner issue. That would have eventually been doom.

Yep. I was crazy lucky it didn't let go on the dyno. I'll take it.
