What would a P7100, S357, 5x12's, and an A518 get me?

Besides being a black sheep on this forum?

I've been kicking around the idea of going back to a single mainly because I want to reinstall my liquid cooled transmission cooler back in the stock location.

Do you think an S357 could put out 400 whp (thru a slush-o-matic) with the higher rpm fueling of the P-pump?

[oldestof11]

The S357 schied sells as their "Lightning" turbo made 414hp on my buddy's seriously overfueled VP44 truck.

As Jon alluded to, yes it would do it, but it would be toasty. With the amount of petroleo a P7100 can move (and when), you'd have a lot of turbo options to get useable power. But that's changing a lot of parts and forking out a lot of money.

IIRC, Sutter1stgen has his heat exchanger mounted on the front cross member. That may be easier to pursue...

Buddy of mine dyno'd 1hp less than me with this same setup, minus the a518. He runs a getrag. He adjusted the overflow spring or something, and gain substantial boost, egts, and seat of the pants pull.

Pretty sure he can hit 1500 degrees no problem.

Oh and he made 357/7??

[oldestof11]

I forgot you had a non-lockup auto. His was a NV4500.

When I mean overfueled, I mean WAY overfueled. EGT's during the run never got hotter than 1150*. His 150hp injectors may have been closer to 250hp according to some injector builders. That little turbo hit somewhere around 45psi.

WAY overfueled.

EGT's during the run never got hotter than 1150*.

Isn't this somewhat (extremely) contradictory?

[oldestof11]

Pullers use the same idea. Too much fuel means not all of it gets burned. The result is that is sort of puts the fire out. It results in a cooler exhaust temps.

[Tacoclaw]

So in other words it's the complete opposite of what he's looking to do?

[oldestof11]

If I understand you correctly, the answer is yes.

[The_Head]

I'm just kicking ideas around at this point, although I could go back to a single without spending very much money at all. The P7100 swap would take a leap though.

Since we're in the idea stage, I would also like my P7100 setup to be as smokeless as possible.

If you want anything more than 500hp, it seems the 13mm pump is the best $ for $ upgrade beyond sending the pump out to be worked over.

[The_Head]

No, I only want up to 400 whp. That is what I was told my tranny could take.

I think I am going to run over to CF and look up some dyno threads.

Having a 12mm (dodge) pump converted to a 13mm (good for 1000hp and up) is about $2700-$3000 an expert told me I could get 6-700 outa my 215 with out taking it off (I'm sending it to him anyway)

On topic the 300g is a good stock replacement turbo IMO and not much more you could run the stock p with it and be fine. I personally ran the 300g on my common rail and was pushing 500 but not efficiently

Why ditch the twins?

Before I threw hundreds of dollars at a P pump conversion and different injectors, I'd try to mount the heat exchanger somewhere else. Just my $.02.

If my mind is working this morning, both the water and the trans fluid are under some degree of pressure. So that should mean moving it a foot or two away won't make a difference.
