We just finished a obs, 238/200s adrenaline pump, and a modded h2e. Cant keep a input shaft in it long enough to do anything with it. Billet suncoast should be here this week.

I ran them in mine for awhile, pulled harder up top than the 100's did. Very easily manageable smoke too. I even towed a time or two just to see what they would do and they were fine in the right program.

Why not stroke them a little more while they are out? Take them out to 300 or more so you have plenty of capacity to work with.

I was thinkin bout gettin them stroked out to 300cc but jim only goes to 238's..... he built these and was plannin on sending them to him for new nozzles. guess I will give him a call on tues and see what he can do. I am going with a s471 so air shouldn't be a problem

300/200's with a modded h2e or 42r would be good for 600-650hp with good oil/fuel

Suns PSD do you like your setup with 350cc 200% injectors? do you get good MPG with them? can you turn them down and tow with them? or would they get to hot?

Love them although now that it is warm outside and since Biodiesel is no longer available they do give me a bit of unwanted smoke if I'm not gentle on the go pedal.
I only have one do it all file. It's soft down low then screams up top. I have zero egt issues and I can tow or whatever.

But he has twins...that'll make a huge difference. You could still build a tune that would let you tow even if you had a single though.

nozzle size 100% is just 100% larger than stock 200% is 200% larger than stock. I THINK!!
