I am currently working on a new car for my car company, Traxx. I am building a modern muscle car and I would like someone to give me some help tuning the engine, or you may submit an engine and get the credits for creating the engine when I’m releasing the car on my car company forum page.
What I would like is:
A modern V8 Flatplane engine, year 2014. The engine shouldn’t be very big as it shouldn’t be too heavy (because of economy), but my goal is to have about 500 hp. Economy is very important, and so is production units and production costs. The pord. units should be 250 or lower, and the building cost should be below 2500. No race parts as I want it to be a road legal engine.
No limits except for what I wrote in the post above.
Year 2014, not too big (because of weight), about 500hp, good economy, max prod units and max price listed above.
I said that I am building a muscle car and want a engine to fit a muscle car, but it doesn’t have to use all the same parts that are typical for a muscle engine.
Well, I don’t know what would be realistic for an engine with 500hp. But 30% would be good, but if you’re a really good engine designer, then more would be just fantastic. Most engines I design myself have an economy of 26% minimum to about 28% maximum
Hopefully this isn’t too big. On the plus side, I think I’ve kept the production units reasonably low. You can also get it under 200 kg by switching the block to magnesium and ditching one muffler, if desired.
Thats correct, but I said that it should be street legal, and I don’t think 100 octane fuel is easy to get in most places of the world at a regular gas station.
Well, its supposed to be a very modern car, and I personally like flatplane, but if you have a good crossplane design I will of course take a look at it!
I’ll toss my hat in the ring, may not be crazy torquey like the others, but it’s a nice even power curve and it doesn’t cost an arm or a leg either… well for an exotic V8.
Basic Stats:
4.7L 32V DOHC with Dual-head Direct Injection and VVT/VVL
Aluminum-Silicone Block/Head
Forged Steel Crankshaft
I Beam Steel Conrods
Lightweight Forged Piston heads
Design principle: A sporty V8 that can run on mid-grade gasoline to help owners save on gas costs if they choose to go to the track on the weekend. However, it’s not a snorting monster and is tame enough for everyday driving.
With this entry I’m keeping initial and service costs down by using MPFI instead of DI. It’s a fairly compact 4.6L (a couple ticks smaller and it would be a 4.5). Reasonably low weight, good reliability, and over that magic 30% efficiency mark that was mentioned earlier.
I hope I’m not too late, but I only found this thread last night and remembered my password just now. Anyway, here’s my engine, let me know if you want it.
I personally just look up the specs of a real proven v8 like a chevy 350. You can find the bore/stroke anywhere from wikipedia to forums. Build it real basic out of cast iron at first, get it running reliably then free up the exhaust and start cranking ponies out of it.
