Better way.... Race track with a scale

 

x2 on the track times

for what its worth, just got done helping a friend out with his truck. 180hp ppump no plate with a 62 mm charger went 12.48 @ 107 !/4 mile 7k truck with driver.

 

Thanks I had forgot about that

Was that all the mods, just plate MIA and a turbo? I would think it should take a little over 500hp to get you in the 12's with that much weight.....

 

normal pump tweeks, injectors, 62mm turbo, and a built auto. calc says 592 rwhp to do it

 

Well if it isnt Dave! Havent seen ya around here or CompD in awhile. AND for a side note, if I were you I would take the plate out, do the afc mods along with tuning it and you will be golden.

 

Dang thats crazy I dont see how. With 5x.014's I wouldnt think that would even bring you above the 500 mark

Id like to know what he did!

 

If the plate has nothing to do with fuel mileage, why do people want plates that give some power, but keep fuel mileage. Are plate choices just given for power preferences and to keep reliability??

 

I think so. As far as I know, the pump should only give as much fuel as your foot is sending it, with the max being determined by the plate. With two different plates, one aggressive and one mild at a set rpm/speed, and under the same load, they would burn the same amount of fuel. Now if you have it floored at are at max boost, the aggressive plate will inject much more fuel than the other, and thats where you see mileage drops/gains.

That last paragraph was all guesswork, but it makes sense to me. Anybody feel free to correct me

 

That does make a lot of sense. But getting back to a #0 plate and running plateless, how different is it? Does running without a plate dump to much fuel in the pump not being beneficiary, and just wasting good fuel? It would seem that have a #0 plate is a big road block for mass fuel to be dumped, But im not to knowledgeable on the flow of fuel through the pump to make a correct statement.

I understand to that the EGTs would be lower with a plate compared to without. Is the #0 more efficient still giving the pump max flow without over fueling it to much?

 

Like was said before, running plateless is the same as running a #0 full forward.
