Welcome Everyone, So I will give a quick run down of what this is, I've read heaps of the forums on here, especially those based around performance gains on the good ol' Crossflow. This forum, will be a kinda build topic, showing the build of the engine, specs, asking for help, giving you people information on what's happening. But most importantly, I wanted to create a forum, where I tell you guys what I'm doing, and what's going on, and you can give me specific answers and help to my issues and wants. Yes I know, there are heaps of build threads and forums and posts about gaining performance, but I want a post and forum specifically targeted at what I'm doing, so I can gain personalised help, as well as give results and insight to what I did for future project goers. Okay, so this is whats up, I started this build 5 years ago, and you can check it out on my other forum "Sleeping Beauty", I'm not going into detail with the build here, only engine related components. Alrighttyyy into the nitty gritty, quick rundown, engine rebuilt, everything nearly new, entire engine is balanced internally and externally including flex plate and pulleys. When motor was new it had a dry cranking compression of 210PSI. This is what it is running: - Stock OEM Cam - .050 Duration Int = 190 .050 Duration Exh = 190 Cam Lift Int = 234 Cam Lift Exh = 234 Valve Lift Int = 407 Valve Lift Ext = 407 - 350 Holley Performance Carby Jet Size = 52 - Redline Performance Manifold - PaceMaker Headers - 2 1/4 Inch Straight Pipe with Straight Through Muffler - Unknown Compression ratio, only know 210PSI dry cranking pressure - Converted to Unleaded Valves - Running 98 Octance Fuel - Mechanical Fuel Pump - Thermo Fans - MSD 6AL-2 Programmable Box with XF EFI dizzy and 8.5MM plug wires Okay, so that's a run down on the motor, I ran it in over 1000kms, and god was it a bitch, this thing had like 65 jets in it from the factory Holley tune, and it had original points ignition, so it just died, bogged, sucked absolute monkey b**l. Okay, I'll leave you guys with this last information, and will do an update in a day or so. I got the car dyno tuned after it was run in, had massive issues, the throttle wasn't even opening to full throttle only half, and when we did our first run, without any tune, we got a powerful 40RWKW, WOOOOO hahahaha So we fixed the throttle position, we pulled the jets straight down to 58, and then advance some timing, slowly slowly the power came up. Eventually, we ended the day on 53 jet size, timing, and without air filter 110RWKW and about 380NM of torque, and with the air filter on I lost 10RWKW, WOW, so turns out the air filter is super restrictive. Anyway, I'll leave you guys without for now, pretty late when I was writing this, will post some picks up with the work I just spoke about, and will then tell you what I've done next, where I am going, and ask a few questions I need help with. Thanks, harry ​
