Looking at the dyno sheet, I’d agree with you…but that’s not what my buttometer tells me at the moment. So, what would make the power fall off noticeably after 5300?That's my point . You need torque.
You got no torque from gear because you got no gear so it's all engine torque and you only have 2 gears .
You need to use every ounce of engine torque you have .
You're saying that torque drops off fast after 5 grand therefore you think shifting sooner is better .
But By doing that and falling back to 3400 on the shift you are coming out of first and starting in second with quite a bit less torque and hp than is available to you. Thats why I'd think youd want to stay in 1st as long as possible because gear is what you lack .
When you are higher up in rpm you have rpm and hp is climbing on your side .
Look at the dyno .
Instead of starting out in second at 3400 and 565 torque and a measly 360 hp why not start out in second at 4 grand with 600 torque and your 450 hp at that point which will pull the big heavy load with no gear out of it's own way and get into the available horsepower versus running 1st gear to 360 hp .That way youd see close to max hp at then end of the show .
Just my 2 cents.
I could be wrong but I'd certainly try it .
Nothing to lose
I’m going to pull the valve covers and inspect the valve stem tips to ensure I don’t have any valves floating, but I’m betting it’s fuel supply, and I’m not talking about the 750 cfm carb. Bumping up to 1/2” fuel line is probably a priority at the moment.
I have the RobMC pickup, I need to pick up a roll of 1/2 aluminum line, assuming it works with today’s garbage fuel.
