The engine specs on some of the vehicles so far are quite unrealistic.. The Gavril 4.5L V8 for example has around 90-120NM of torque at its peak (3000rpm) more than an engine of its size and general year (early-mid 90's) should have.. Also the redline is a bit low for what I'm assuming is a SOHC 16 or 24Valve engine.. If it were OHV 16 valve the redline would be about right, but given the similarities of the Gavrils to real life Fords I'm assuming the 4.5 V8 is the equivalent of the 4.6L ford modular V8 which is SOHC. Also the torque curve isn't really realistic either, it drops off far too quickly for a V8 of that size and valvetrain.. It makes it really hard to mod balanced and realistic engines into the game when the existing ones are over powered.. I've modded a few of my own engines into the game that are based on real world designs. I use the engine builder for Automation to get realistic Torque figures. I would highly recommend using automation as a tool to aid in the design future engines. I haven't done any in depth comparisons to the other engines like in the Moonhawk or Covet yet, but I could point out any flaws in those engine specs if I had a look. Here is an example of a more realistic 4.5L V8... I left the redline at 6000rpm to be consistent, but realistically it should be 6500-7000.. I'm not saying these engines need to be 100% accurate and true to life, that would be impossible.. Even Automation isn't perfect, but it is about as close as it gets..
