For those who want to aim for less than 500 hp would good quality injectors produce more cool power than smaller sticks and a fueling box? Is widening the pusle width going to add power less effieciently than adding fuel through bigger sticks?

Picking examples from the crowd,... how about Big Blue's truck when it was at 400 hp (ac off) with comp and 100 hp injectors vs Bob Wagners setup with catcher and mach 4's. If the turbos performed the same who's truck would be cooler? I'm thinking Bob's would be. Not trying to single you two out- just using your trucks as examples =P

I know your talking about WOT temps, but Bob's truck is stuck at the power level. BB can reduce his trucks power to right around 300hp.

This is just a guess but isnt 400hp going to require the same amount of fuel not matter what (assuming identical chargers and pumps)??

But if a F1 injector, say a mach 2 (105hp) can produce that power at what a cheaper Jammer Nozzle stg IV (125hp) will produce at a higher temp then I definatly agree with what you are saying. Because I dont think Jammers run as powerful and as cool as some others out there.

And just for conversation, I would bet bobs 400hp is easier on the pump since there is no wire tap. But thats back to 400hp should require a certain amount of fuel so the pump should be working just as hard on both trucks.

400hp worth of fuel will be the same...but the manner in which the pump works to GET that fuel is the difference!

Also, now that we have the Smarty, the power is adjustable with only injectors...granted, not on the fly, but it's still adjustable!

Of course I'm a 12v guy...right now I have 2 power settings, valet and full fuel, with another in the works at a later date (nitrous on/nitrous off)

I think this is why you have always ran cooler then me. My injection pulse is just to long. I've thought of adding some mach 4 and leaving the TST turned down. Even at the lower settings I could make just as much power as I am now with lower EGT's. JMO

400hp? Dude, that was so yesterday. I know that with the BD155's, TST/Smarty, and 40psi out of a KSB-1, I can peg 1500* fast enough and long enough to make the water temp start rising.

IMO, A 400hp truck with injectors and smarty or ez will run cooler at WOT, than a truck with smaller injectors and a wire pump box.

Only if Bob's foot were stuck to the floor =P
I couldn't tell ya. I've been told that big sticks are easier on the vp somehow, but I'm not sure if thats true.
Yes that is the heart of the question right there.
I was thinking of pming ya to ask what your max egts were on the 64 when you tried it since we were within around 20 hp.
Like how I gave ya 2 hp for turning the a/c off
Thank you

so basically y'all are saying that bigger injectors and a non wire tap box would/could produce the same power with lower EGT'S? is that right?

Ph4tty

Thats what I'm thinking, but I'm hoping to learn form those who have more knowledge and experience than I

The thing that always comes up is adjustability, but from my experience the right foot can contol power easily enough. An adjustable box might be just the thing for someone who's going to let other people drive their truck though.

I'll put my two cents in. From my experience the box makes thing hotter than just injetors. I run a TST box and have been told that it runs hotter than and edge. So now my story. If I run rv275's, smarty 9, and TST 9. I hit about 1400*. If I run my BIG injectors 230RWHP, but I only see 180RWHP (stupid HO pump) and smarty, NO TST I only see about 1200*. I'm not sure what the first combo dynos at but I know it isn't 400. The second one I know dynos at 430RWHP. If I turn the TST on in the 2nd combo I dont know what the temps are cuz I only have a 1600* pyro.

With the 64 It was a little bit slower to riser but I could still peg a 1500* guage.
