    RR Merlin Build

    i would definitely do billet, but maybe nitride the crank for strength. i would also redoing the bearings and the oil system as it was a weak spot on the engines to begin with. I would throw away all of the older stuff and go with a redundant set up, the question is running advancement timing...

    Designing the Ideal Replica Warbird Engine

    your tractor pulling using methanol, IMO your better off getting a handle on a pair of 6.7L Cummins engines and mating them together. your limit is about 2,600lbs give or take there are a few engines you can buy (diesel wise) that can put you there, with modifications of course. My advice is...

    Designing the Ideal Replica Warbird Engine

    Sorry i have been out and about working alot lately, and working on my Cummins, i have a shift kit, new Injection pump and turbo to rebuild/install. I did injectors and a slew of other things just need to keep her fixed and running. If memory reminds me right, i was thinking of pressurization...

    Designing the Ideal Replica Warbird Engine

    Yea, that looks really close. the upside is you can find alot of Diesel engines that are of the same size that you could steel their sleeves from, or make your own. The big displacement diesels use this technology because it makes overhauls easier and more cost effective, Imagine a TBO on this...

    Designing the Ideal Replica Warbird Engine

    I have always been a proponent of wet sleeve technology. My Merlin design was that of a single bottom eng, that was cast, and upon that the sleeves were pressed in with the use of loctite sleeve compound, and then the outer water jacket was nothing more then a large rectangular wall that was...

    Designing the Ideal Replica Warbird Engine

    Can i ask what program you are using for your engine building, the pictures i see are good enough to want to see if it can perform stress tests and such.

    Designing the Ideal Replica Warbird Engine

    Well worth the trip i say. The reason being that i have spent many years following designs, and they all followed the RR Merlin architecture, tagged with Wet Sleeve technology, as a result as i pushed my knowledge limits of P-51 design so did the engine configuration. Eventually you will get to...

    Building a twin mustang

    The Falconer was over 60,000 the last i checked. The Allison like their Merlin counterparts are in the six figure range for a good working model, that means for Don he would drop over 200,000 for motors, assuming these Allison would run, most likely need to be rebuilt, and updated. I could see...

    Building a twin mustang

    The Viper has a superior firing order that doesn't require a balancing shaft, and if you lowered your compression down and added forced induction should help out alot. While i think i would differ 100LL fuel running about 16psi will get you 600Hp. Not this is also at sea level. Running a...

    Cost Of Full Size Replica

    i got a quote from a few places for a full sized P-51D with a re forced wing and frame was about 900,000 USD, including labor, considering this is about the cost of an existing one i figured it might be worth it to just have a brand new air frame. The only problem is a newly built one would be...

    Twin Ford V10s anyone...anyone...

    hey Don! Im back, i have been concentrating on other stuff and have put the whole thing on the back burner.

    Designing the Ideal Replica Warbird Engine

    The reason i would run 91,(and preferabally 93) octane, is because even big block motors run high octane to help lean out the mix, because your risk for pre-detonation is very high. Well, going back to my books the engines i designed all had low rpm limits. The difference was the V-6 model...
