Well my exhaust is the same so I assume it's from the cubes/hp gain. My car was not as loud as my buddys C6Z before the new short block and smaller pulley. It is definitely louder than his Z now.
JLayer how much do you love that car rockin side to side at idle now? Thing could rock me to sleep.

It gets going a lot at times. My wife rode around with me a little yesterday and asked if this was normal now. I just smiled.
So sorta final numbers are in. There's still a little tuning left to be done but since timing was not optional for me and the tuner, it'll have to wait a little bit longer for final numbers
However it's pretty dialed in on the SD tune. It blew a belt at 6300 on the last pull (that was my fault, I had a old belt on it) but it was still pulling. He said it showed 11 psi and threw down 733/641 at that point.
I have a graph but it's not the best but overall pretty stoked about those numbers especially on pump gas.
The car should be very drivable for me for the HRPT coming up in 2 weeks. I'll try to get it back to the tuner after to complete what's left which is cold start settings. Hopefully imwe can give it another shot. Need to find a green belt as I'm still on 6 rib at the moment.
Commendable. And on a 6 rib. I saw that Gates had the RPM line of belts available again. Prior to the covid changeover they used to be pretty tight. Not much flex. I have yet to hear experience from anyone running the newly released line though.
That's more power than I've driven before. Let us know your real world experiences with it.

Where did you see that they are offering the RPM belts again? I wouldn't mind trying one of those. Although my green Fleetrunner has been holding up pretty well.
Car is back to my builder. After discussions with him/ECS/vortech, I'm doing an 8 rib upgrade on all pulleys.
The last belt snap took out my oil drain line so, we are going to relocate it out of the way of any belt path. May have to replace my pan because it ripped the fitting out as well
Also, while I'm taking the h/u off, we are going to add a oil pressure regulator for the feed line. I feel like I got too much pressure going to it due to the oil pump. Turbosmart has a new regulator to keep the pressure where it needs to be with blowing out the seals.
Needs to go back to the tuner as I believe I had major belt slip (dust everywhere) and adjust for more boost. I think it will see closer to 14 psi compare to the 11 it saw on the last Dyno pull.
Hopefully end of aug I should have everything line out.

smart man 8 rib above 600 or so hp is a wise move
the new drive4 systems from A&A and ecs are worth the price of admission At that hp I'd consider an IW 10 OD balancer They allow you to run a bigger pulley on the blower and still make the max spin
the new drives make the 8 rib I think all you need
8 rib pulleys finally came in this week. We are hoping the pan doesn't need replaced but I bought one just in case. I have to take the parts to him next week.
I have it scheduled to be retuned on the 26. I'll update if we have any belt problems on the Dyno. I'm throwing a gates green belt back on. If not final numbers will be posted.
Vortex told me not to run the feed line regulator since they put restrictors in the line.
Like Ron said above, an OD hub allows you to run the larger head unit pulley and have more grip and wrap while reaching the same boost if you still have belt issues. Hopefully not.
Pro tip - forget flex fuel as an option if you've built with that in mind. My second car is a straight E85 tune on factory ecu and it has been an absolute headache chasing injector and rail O-ring leaks due to the fuel having eaten them when the car was parked this spring. It has turned me off to the idea. I'll use octane boosters or C16 if I ever go nuts, but I have also learned that going north of 800 wheel is a whole new driving experience. That is exactly what I wanted to attain. It puts an INSTANT ear to ear idiot smile on my face, but then I'm immediately on the brakes again. While the car is upgraded to handle corners at speed, the kind of power it makes (it dyno'd 850 at 10psi on pump, now 16psi on E85 and tuned but no dyno number) and the delivery of that power means I cannot apply throttle coming out of corners so the car becomes a cruiser and a saturday night special or highway ripper. I basically wait until the highway is empty and goose it while the tires haze and don't really stop until I'm on the brakes. LOL So I am enjoying this experience but it is also curbing my plans for the twin turbo build which I really wish was a forged 377 or 346 with small heads and cam now and just a docile mouse which relied on boost alone for the power. Because those turbos will make honking big power for sure. But for me I now know I don't need the big heads or cam to be knocking over 1k, because I really can't USE 1k and it takes the car away from the weekend hill ripper I need it to be to be happy. So I may revise the cam spec for a THIRD time prior to finishing the project and go small.

It is exiting. im just ready for it to be done. The car hasn't been in my garage for 14 months now other than the brief moment I was able to break the rings in.
I'm hoping a smaller belt, 8 rib, and a new bracket to clock the tensioner higher will solve all the problems.
Yea I'm sticking with pump gas. The thought of running e85 never crossed my mind.
I hope you get it sorted out. I certainly know how frustrating it can be. It got to me so bad when someone offered me a stupid amount of money for the car I sold it. Highly modified cars are most likely in my past. Best of luck J.

Yep! As with any big build it generally takes time to work everything out. I was getting very frustrated with all of it. I didn't have the car for sale but a gentleman who knew the car from hanging out at the shop that did the build really wanted it. Offered me a very good amount so I walked away from it.
The car is now back in the shop getting a ysi, holley terminator and better fuel system.
