most drop on turbos ate not that big.. so depending on turbo specs, the srp pump can prolly handle way more then the turbo.

I imagine nozzle size would be more of a factor than "body" size??

I have a customer running 350/200's with good results so far. The pump is defiantly keeping up for sure!

We are going to be trying a set of 400/400 with a srp1.1 will let you know how it goes.

Dyno/track proven numbers will be hard to come by....as far as a direct answer to your question....I will only add to the above conjecture and speculation.
I think there's several SRP1.x and 400% nozzle combos out there now.
If I recall, Nate @ Unlimited is running 400% nozzles and a SRP1.x....unless I recall incorrectly....I think that's what his write up in DP said to. 40ish% duty cycles, but not certain that was with max PW tuning though. I couldn't get DC% above 43-46% no matter what I tried with some 200% modded Unlimited injectors and a SRP1.0.
If you look at RockinJWs old truck (#9 on this list)...I wanna say that was a B code\GQSSB\"big oil"\WOP motor combo, and that made a bunch.
So for you combo....I'm gonna say...a very big number with spray before you find the SRP1 is your limitation.
You looking for a number at the dyno or the strip?

I have in front of me a graph for 300/200, srp1, 38r for 561hp.
This same setup previously ran a D66 for 525, then switched to the now defunked Precision for 550hp without any other changes. That was without tuning for the 300/200's with these two runs. Now that it was tuned, it has done more with the 38r.
I have done several combos with 200% nozzles and srp1's with great success. Now moving to the 400% nozzles I think we will see the limits.

It holds 3000 psi fir me with mid 30% DC with 250/200.
OK, wow. Had no idea the srp could handle these bigger injectors. Thought I was getting out of 7.3's and sold my stealth twin pumps. Tried to sell my built engine, but no takers. So new project! 68 f250 2wd on a 2000 f250 frame. The precision turbo, built engine, srp1.1, injectors to be determined, and a whole bunch of n20.
The stealth twins were great, but obviously huge, and always leaked. Looking forward to a stock bodied pump in the valley.

That truck looks like it's got some good bones for build.

Has been enough for a 12.34@110 @7900lbs puts it around 690-715 according to the calculators. That is the S468FMW, 350/200's and the SRP1.1 Just our experience with it and holds right at 3000psi @ WOT when tuning is @ 3ms.

I currently run a srp1 with 300/200s. The numbers are similar to Marty's concerning icp and dc. Can the srp1.1 really run a 400% nozzle though and keep up? I'm not saying it can or can't, I would just like to see some numbers on large injector like that!

With 350/400% it was getting up to 40% DC. Which is the max Gary said you should go. But it was not tuned for the new setup yet. Will have to see what happens then.
