Im not braging by no means, but the pump was flowed and flowd close to 990..... I bought the pump used, it is a 13mm pump. I know it has had alot of work done to it..... Im still tryin to fiqure out what charger I need, I really dont want to tear my charger up by over turing it.

 

Re-reading, you are right. Thought it was you that posted it was a stock 215 pump, now see its someone else. My bad.

As for turbo, if you are gonna run in a 2.8 class, I'd be looking for a S471, or a 71mm k31. K31 is wastegated internally, so you need for an external gate. But you can tailor the S471 to your needs. I'd talk to ED about what you're after. If you can run a bushed turbo in the 2.6 class, then you should be good to go. If you have to run a true 2.6 turbo, you may want to rethink the 2.8 turbo. Unless you want both and will switch them when needed.

 

In the rule book we cant run a bushing from a 2.8 charger down to a 2.6. i would like to find a charger I could get an 2.8 housing and a 2.6 housing and change them between classes. Most everything up here, we just do weight classes, with an 400 under class then a hot street, class.

 

might need to look at your rules very closely... It may say the compressor must protude into the 2.6" bore for 1/8" or so. If so you can't just swap covers for each class. The rules would have to say they only check with a plug.

what turbo to run? 990cc's is enough fuel for a triple charger setup LOL

 

They do only check with a plug. Atleast for the last few years they have.

 

I'd get a hold of Engineered Diesel and have them make you a turbo... that's really going to be your best bet when pushing 990cc's on a single turbo... they'll be able to supply you with a legal cover for either class too

 

I have a newbie question, I'm buying or getting a 13mm pump done up. Everyone rates the fuel deliver size differently, its hard to see how the pump are really set-up. I have one shop says that you can get 800cc of fuel at 4000rpm for a 13mm pump. I really have a hard time seeing how one shop using similar sized plundger, barrells, can have flow numbers that different. Does the cc's deliver change for different engine rpm's or does that remain static?

 

CC's are all in the setup... delivery valves, amount the barrels are turned, cam in the pump, etc....

 

So how do you know that the pump is still have the ablity to fuel at higher rpm's? If you run the agro gov, how is the fueling plate work? Sorry, just want to know abit about this stuff prior to spending money on it.

 

I don't believe ag governors have a fuel plate...

a 13mm pump with an ag governor is a serious SOB...

 

Lots of fuel, but the trick is getting it to make power. I want to rev my engine up above 5'k and still make power.

 

Only gov to have a fuel plate is the RQV.K. RSV and RQV gov's don't have plates, just a rack stop.

 

Whats the rack stop for? For the AFC and you should still have full rack travel? So an agro will fuel the same amount regardless of engine rpm, but is variable adjustment is just done by AFC. I kinda thought that with an agro gov, there would be no need for a plate. Thanks, its slowly sinking in.

 

to limit the amount of fuel delivered.

The pumps are mechanical and require a means to limit the max fueling. Whether it be the fuel plate in a auto gov pump or the rack stop in an ag gov pump.

 

I found out today, its the device that rotates the plunger. The stock pump limits the amount of rotation. Basically adding more fuel. The AFC stops the movement on the fueling plate, until the certain boost has been reached. Hopefully thats correct, I had a 15min P pump class today.
