ok well they built up a methenol engine......

Well they said by changing the 7 and 4 spark wires, they gained 8 HP???

I know we run on gas, and things may be different, but does anyone think its possible to do a wire change on our trucks to maybe get a bit more bark?



i just thought this was pretty interesting.

 

What "change" did they make? Did they put new wires on those spots? I seriously doubt that they switched the firing order there.... that would be just silly, as it would make the engine run like crap.

Did they install them wrong initially??

 

I was watching that today too

 

no this is what was said "And by changing the #4 and 7 spark wires we were able to get 8hp more"

 

It also requires a 7-4 swap camshaft.

 

And swap the 7 and 4 injector connectors? This isn't a batch fire system. You can't alter the firing order without doing some SERIOUS hoop jumping.

I suspect that they just had two bad plug wires, and replaced them.

 

possibly, i was typing on here when i heard it. I may have missed some important info, but if my memory serves me correct, they mentioned nothing about injectors being swapped, or what not.

They did put in a new cam, but i dont remember them talking about the 4/7 alteration.

 

Yeah I was watching that too......had me wondering what the hell was going on . So you are not the only one .

 

ok just watched it again..(dont know why the repeat the same episodes the next day)..it is the cam that allows for the 4, 7 swap.....

 

Um, ok...... they put in a cam that swaps the firing order on 4 and 7, reprogram the PCM to account for it, and get 8 whole horsepower????? Erm, you will have to pardon me, but, spending a couple hundred bucks on a cam, and a few hundred more for a custom tune, to get 8 horsepower seems hardly worthwhile to me....... They could have spent under 300 bucks on some better rocker arms and gotten more than 8 horsepower......
