How To Tune An Engine For Maximum Horsepower And Torque

On this PowerNation Extra, Engine Power's Mike and Pat show you how to tune an engine on the dyno by measuring fuel flow to get maximum horsepower and torque. Because who doesn't want more power?

Dumb question. My builder will be tuning my engine before sending it back. Would I need to then returned my car after its back in my car?

How to tune an engine, video 2:55 long. HMMM

[@flinch622]

Is it just me, or does Pat need to go full hippy up top to go with the beard, like early 70's style?.

He and Mike Galley are Beard Twins!

I can't find one video on RUclips that discusses how to increase low end torque

[@musclebone7875]

Easy! A camshaft swap, stroker kit, or dual plane intake

[@TrentGustus]

@@musclebone7875 ok.. question.. would a better flowing head with a larger valve increase or decrease torque on the low end or would it compromise it. I've got a 455 olds with a 70s smog head, smaller valves.. I can't change the intake.. i want the range of torque to be low.. reving 3000 max

[@musclebone7875]

@@TrentGustus A better flowing head can sometimes increase torque, but usually it increases horsepower up top. Usually to make good torque and horsepower in is the combination of parts. First you need a camshaft that's for a certain RPM range. Since you're looking for alot of low end torque, you need a camshaft that starts making power around 1,500 to 2,000 RPMS. Then you need compression ratio, decent flowing cylinder head. Stock heads will make good torque.

[@TrentGustus]

I have an olds 455.. with stock J heads which was the smog head... smaller valves, but I have some stock heads that were off of a marine engine.. higher flow big valve.. all the literature tells me that the smaller valve heads will be better down low.. but then since most boats require low end torque.. wouldn't the marine heads naturally be better? This is in a motorhome.. so what I really need is torque down low for mileage and to pull up hills.. and I need a smooth cam.. probably what's in it now.. I also have been trying to find out if Throttle body injection would increase torque down low.

[@musclebone7875]

@@TrentGustus not necessarily! Most boats like RPMS between 3,000 to 4,000 RPMS. They do need to torque, but mostly in mid range RPM band where as I'm assuming you want most of your torque under 4,000 RPMS. you would want to use the smaller Intake port head. The smaller intake port volume head will usually make the most low end torque.

That Ed or show just tells you the reading of the dino not doesn't even they don't even tell you what to do to tune your car it's all f***** up

[@chaztitan6457]

maximizing horsepower is all you need. saying maximizing torque is literally redundunce and dumb.... increasing tq at any rpm results in increasing hp.... so its like saying, should I make more money per hour or more in salary....
stop being dumb

[@Nikolai_The_Crazed]

Oh believe me, they are two very different things. Increasing torque increases horsepower, yes. But the torque is the amount of energy propelling the vehicle, it’s the physical pull of the engine. You can have a lot of torque, but if it’s only accessible at higher rpm, you have to floor it to feel any of the fun. Not always feasible on a public road. However, if you can bring more torque to the lower rpm’s, you get more low end fun. It’s more useable. It increases horsepower, but the end result is very different to just blanket adding more torque. One pulls when you rev the engine harder, the other pulls when the engine is more around the mid range. It’s similar to the difference between a muscle car, and a sports car. It’s about putting the torque where you want it/need it for your applications, so that power is more useable. Hence “maximizing torque.”
