It would be about 2 1/4 to 2 1/2 hours west of Knoxville. I have a pair of Eddies 750 EFI,s in my Black Thunder and I love them. Joe Murray.

Eddie great job the motors look awsome i like the set up on the back for the electronics with a flat toque curve they should do well in a boat. Hope you and yours are doing well i have not talked to you in a while just to let you know the blower snout is working great so far thanks for the help

Hey Mike,
Everyone is doing fine. Glad to here the Whipple snout that I made is doing good. Keep in touch.

Catmando,
I have beat the idea around for a long time about the turbos. I have been working it out on paper for several months. Trying to come up with a better mousetrap, so to speak. Before I built the first quadrotor, I built it on paper for 6 months, so when the time came to do it, I knew exactly what I wanted to do and was able to make 1211 hp on 91 octane and 1414 hp on 100 octane. That is how I am approaching the turbos, doing the research and working out all of the problems that other engine builders have had and other potential problems that may arise. I feel that I am very close. The biggest drawback that I can see is money. Unless someone wants more than 1500 hp, I would stick with the quadrotor or the 5 liter(whenever it is finished) and not consider a turbo unless they really wanted it. Anyway, I will be ready to do one soon if someone wanted me to build it for them. Thanks, Eddie

Eddie,
Do you have a complete machine shop of your own and do the machining in house? Whose dyno shop do you use?

Re: Young Performance 750- Latest engine
 

Here are some dyno pics. The dyno belongs to a friend of mine that builds engines for guys that run roundtrack at the Nashville Speedway. He also dynoed 2 engines that went to the Jeg's engine buildoff.

Dean, do you feel that it is better to do all of your machining in house?

Re: Young Performance 750- Latest engine
 

1211hp on 91 octane!? :eek:

Ok, in that case I'll take two - screw mild power! :D

Re: Young Performance 750- Latest engine
 

Dean,
I do not do the machine work. I'm not a machinist. I know what I can and can't do. I certainly can do all of the machine work myself, but I choose to have someone better than me do it. I have been using the same guys for over 10 years and they do EXACTLY what I want. I give them very precise specs to hit, and if by some chance they don't hit the mark, they will get it back to do over. That has happened once in 10 years. The same guys have worked there, so the man who balanced a crank for me 7 years ago, is still balancing my cranks today. They have a 60,000 sq ft shop with all new equipment, totalling several million. I could go buy cheaper, used equipment and do it myself, but why??? They have top notch equipment and are better at it than I am.

Mark,
Now you're talking. :D :D
I dynoed those in Ca. and 91 is the best you can get. I would not run it in a big heavy boat on 91 because it's not enough. 93 octane is ideal.

Re: Young Performance 750- Latest engine
 

Either way - still awesome numbers! :cool:

And you actually stand behind your product 100% - huh, how about that - now THERE'S a novel idea, huh!?!?! lol! :D
