Dem Optisparks are great WHEN THEY WORK. Is the 11.97 NA or nitrous? How much nitrous? Curious.

100% N/A.

Nitrous outlet Hydra nozzle is shipped, and I found the old mallory 685 ignition box in the barn I thought we sold, we verified it works last night so that is being installed this week. Maybe spraying whats left of this bottle this weekend......

Also swapping the injectors from the Jet 30lb injectors to Osies old deka 60lb injectors as he went to 80's on his car. I also think that i MAYYBE have a fuel boiling problem in the fuel lines as the -6an braided line runs up next to the transmission to the Y-block behind the intake, then hits both rails. It seems that the afr is lean thru first gear (mid 13's) but then once i get into second it comes down to where it should be 12.5afr-ish noticed it on every pass. gotta find a roll of the dei -6an heat sleeves and install that too. you figure if the car was gonna go lean due to a fuel supply issue it would go lean in 3rd gear, high load, not all the way thru first gear

Deka 60lb injectors installed. gonna probably mount the mallory box where i had mounted the LTCC. I only have to get to it a few times to set it up then once its dialed in we should be good.20221024_213747.jpg

Did you ever figure out if the Weldon AFPR is capable of vacuum reference?

[Z28pr0jekt]

Let me know if there are certain parts you may need. I should still have a brand new msd 6al (I think that's what it was) and brand new Aeromotive boost referenced AFPR that have been sitting in my storage unit for 10+ years from my defunct turbo build. I also have an early set of @Fastbird 's modified fuel rails for AN fittings.

????????I thought it had 64 lb/hr low impedance injectors in it from Injuneer. How did it get the 30's in it and how did you make it run on the Motec tune for 64's.???

The MoTeC ECU and their IEX 8-channel ignition driver were giving him problems. Went back to the factory PCM. One of the Bosch low impedance 64’s was beyond repair after he cleaned the fuel system. Seems like a lot of parts took a beating when I left it sitting for years. I feel bad about that.

The rails are modified to run in parallel, 6AN into the back of each rail, a single 6AN return welded to the crossover pipe at the front of the rails. The Weldon AFPR is outboard, under the cowl. There's a bung for a fuel pressure sensor on one rail. Shaun wasn’t sure if the AFPR was vacuum compensated. There's a port, but it’s capped. The tune in the MoTeC did not rely on vacuum compensation.

I remember him buying one injector to replace the bad one. But I suppose the progress has outrun the posts. I'm up to date now on this interesting project.

@ injuneer it is, i gotta find a fitting for it at work today
