I have a B18C1 sleeved,84mm pistons,mild head work with skunk2 cams,GT4294R precision turbo on 1600cc injectors

 

i was told around 800 on gas

 

Yeah, mine was showing major problems around 860whp. Anything over 800 I'd go bigger.

 

Mine said fuuuuuuu at 850. Pressure dove bad, and couldn't produce more than 13:1 AFRs.

 

its good to max about 1000 crank hp or about 830whp with not much headroom on a turbo car. good up to about 1300hp on a n/a car (not going to happen on a honda).

 

Question, what pumps are available if you want more power than this?

Surely that power figure varies depending on which dyno you measure the power on and if so which one would be correct based on the fuel flow available from the pump?

 

dual bosch.

 

dual bosch 044 are good to 950+ with Id2000 injectors.

 

dual aeromotive a1000 is what we have no problem but only making over 800whp

 

weldon 2015, 2025, etc

 

Had a1000 ran out at 940hp with Fic 1650's on a dynapak not sure what that would make on a dynojet

 

On my set up I only made about 650hp with the a1000 and 1600cc injertors, and it was runninig out fuel at that hp level!. It was a brand new pump , I had to switch to a eliminator pump and made about 790hp and still plenty of fuel left.

 

Yeah as others have said it is about 800hp they start to run out of firepower. The dual Bosch 044's are very popular choices and as someone else has stated the Weldon pumps worked very well as well. I have heard a lot of negative things about Aeromotive products, but on the flip side i have seen so many people running their products that I don't see how they could be so bad. Personally I have their Fuel filter and Fuel Pressure Regulator and both have worked flawless for me. I think that for the price you are getting a pretty decent quality part. As they say " If it ain't broke, Don't fix it!"

 

Also depends on what fuel you are running and at what pressure..
E85, race gas etc.

 

Can someone clarify the difference between running pumps in series vs parallel

 

weldon for 800+ with some 2200's is the way it goes

 

i think the a1000 is an awsome deal for the price you can get them for, and the amount of power you can actually put down with the unit

 

if you already have a A1000 and wanna step up. Might as well get the Aeromotive Eliminator . It should be a straight swap out. So you don't have to re plumb your system.

And i know of a few cars making wellll over 900whp on it.

"• 25% more flow at pressure than our A1000 Fuel Pump."

Edit: looks like it's a -12an in and -10an out.. (so if you were already running a A1000 , you'd have to swap the line/Fitting from the sump to the pump from a -10 to a -12..)

Weldon is the way to go. Plus the LIFETIME warrenty is nice too

 

Which weldon pump the big ones im seeing can only operate at 80psi

 

I run Q16 not sure if that make a difference

 

For 1000+hp get the Weldon 2345. Gotta remember when looking at pumps at that level, we run a lot of boost so the fuel pressure will be high, where flow is the lowest.

Most of the Weldon pumps will do more pressure than they're rated at for short duration.

 

Ah thank you

 

Running pumps in Series will allow you to make more PRESSURE but less flow, while running pumps in parallel will allow you to flow more fuel but you wont be able to run as high a pressure.

For instance Dual Bosch 044s in parallel will start to drop off in pressure at around 120+ psi...but if you put them in series you'll be able to make 160psi with them...however your flow (amount of HP you can make) on them will not be nearly as much.
