THIS. Not that I would go to strictly DI, because of my situation, but if I ever decide that's something I need to do, it's good to have this information.

Eh about 730-750rwhp depending on how generous the dyno is. I did run a 6.5 60-130 draggy with 89F temps and 2400 DA when out testing on E60 yesterday. THat was starting in 4th gear and rolling into the throttle. Once the drag radials go on, I'm sure it will be quicker. And come winter time I'm defintely into the 5's.

If you dropped the boost down it would probably support E80. I'm hitting 14.3 psi in 88F/2300 DA weather.

Hello Jason, were you able to get more E from this combo?

Since I never got a response to my post, I thought I would shake the tree and see what falls out.

Thanks!

As a calibrator, I feel it is extremely important to get this right.

It is imperative that the Pump control strategy is calibrated for the flow of the pump or it can under or overshoot target fuel delivery especially during load transitions.

Yes there are Short and long term adaptive, but that doesn't mean we should rely on them.

No different than sticking a big gulp on and not tuning for it, Yes it will run with the LTFT taking over but it's not right.

We do this for Cam lobes, changing from an LT1 to LT4 pump, or an XDI twin LT1 or LT4 system.

So I don't see why it would be any different, when moving from an LT4 pump to a Goliath pump.

I would think that Stanadyne or whomever would include this information when producing these pumps.

Like injector calibration is included with injectors.

I am sure they know full well what this pump flows at every inlet pressure, solenoid opening time, fuel temperature etc.
