**************** DYNO UPDATE ****************************
Got the car out to Dyno Tune Motorports today and got it on the rollers, Brian spent some time perfecting the VE tables and making sure everything was safe. We started with the wastgate spring on the JGS 60mm gate and it was able to get down to 2.5 psi! it made around 400 at the tire with the pressure.
We began adding small amounts of boost and the car loved it, by the time we got to 15psi we were around 850 and it began blowing the spark out. Put some new plugs in and tightened the gap, put 2 more psi of boost in it
And that netted us 928/973 just at 17psi. The car makes 900 across the board and is was a damn beast on the dyno. Brian really made the tune his bitch.
We settled with that for the day, pretty awesome that the AMS 500 was able to control the boost very well with co2, from 2.5psi to 17psi. We will be adding 3 more psi of boost and get the car well over 1000 in the coming month. Just going to get some time in it the way it sits, we made plenty of pulls today so I figured we could give it a break.
Here is the graph will post vid late tonight or tommarow. BTW injectors are only 88% duty cycle.
E85 ftw.
Thanks again Brian, the car is a damn beast cant wait to put some miles on it. Going to go through everything tomorrow and change fluids, car just starts up with so much ease and has amazing response

Just read your entire thread, definitely an awesome build and very motivating! I agree very impressive #s did I miss it or what was the final compression ratio on the forged 370?

a/r is around 1.0 ended up with a custom spec cam motion gring max effort e85. it wont let me change the first post, i know so much changed through the build, i always read back through it to see how much I changed my mind and how the car evolved and its not over still but its close.
thanks for the comments guys, sure has been a busy long road
yeah once it sees boost its 900+ across the board. Im about to change fuel pumps and regulator. then heading back to dyno, I want to change out the wastegate spring so I can roll around town at ~8psi, the car made over 600 wheel there and thats fun on the street

not tell'n -ok
Since our builds are similar, about what rpm do you think it will make 8psi on the street? Assuming it hooks long enough to get there.
Some guys run CO2 on the street too which would make it spool faster.

Update on Cable drive fuel pump setup. Due to having a stock fbody balancer I had to get a new balancer to run the mandrel setup to run the cable drive.
I picked up a professional products balancer since they have a 3 bolt hole face. Then I got an aeromotive BBC mandrel. The two will not work together but the bolt holes line up. I took the two pieces over to Mike Rush at MM Head services and he put the mandrel on the lathe and made the two fit together like they were meant to.
Very cool how it works. I have a Waterman Sprint 700 pump on order (flows 6.8gpm/408gph) cable, drive adapter,mount and setup for belt up front on the way.
Still need to get a new weldon regulator then Ill be in business.

Yes no more electric pumps the cable drives are pretty sweet they run them on NASCAR and sprint cars and alot of drag cars have them. Kind of endless fuel potential. Cables are beastly and withstand something like 17,000 rpm every few seasons send the pump back to be flowed spend a few bucks and that's all. Never worry about burning a pump up or boiling the fuel or having to run twin pumps or controllers. Probably most excited about this part more than any other on my car
