if you're trying to max the thing out it would be worth sticking another clutch in there. the graph is lazy, especially for a load dyno, you don't want to give people that impression, i KNOW small twins should spool faster than my single 88.
if the turbo's are that nasty or if you are trying to spare the engine stress then i would get a good controller and roll boost in with rpm.
i guess there is potential for you to still have a stuffy cat back on the car or cats too?

Is there already a thread going (other than the longggg APS page I'm subscribed to) that has info about peoples setups, the numbers their making, their feedback, etc?

P.S. Bump for the fuel questions

Umm thought read in setup that you were using 72cc afr. Not a big deal just curious.Course if someone is building engine can just adjust pistons to get whatever compression they want with the bigger chamber heads.
I would expect slower spooling of course with these. I would just get a twin disc textralia or triple disc textralia already. That should take care of your clutch problems once and for all. Many cars are way past your power level on tex twin and triple.
I would also like to see the fuel afr graphed against the rpm like most dynos show. I want to see how steady that fuel system is at supplying what is needed at these power levels. Not saying its not doing the job just like to see things in writings sometimes. Its still like 2 grand for your fuel setup and want to make 100% sure it will be the last one I need to buy.
I just got 60s so a bit depressed they now have bigger high impedence injectors. But guess that option is now there if I need it. Any idea what duty cycles you are seeing ?
What is max fuel pressure that can be cranked into the injectors anyway?

Ok thanks as usual for the quick reply. Some good some bad stuff in there. Now you have me pretty worried about my tex twin disc as was pretty sure it would handle past 1000ft pounds. There are many guys running the tex single at pretty high torque levels.And sure read about some pushing big power thru the twins and for sure the triples. Not sure what other clutch can handle big power. I guess if get too depressed just goint to convert to 480le and be done with this manual stuff. I am not a big fan of manuals anymore anyway.And much easier to get boost off the line with a nice auto and stall.
As for fuel pressure I guess fuel pressure holding steady would be a good test of the fuel setup. Just used to seeing afr graphs on most dynos.
And yeah was just wondering what max pressure you can use both base and realize if its boost reg that boost gets added on top. So for example what is max anyone has pushed their 60 siemens to? I have those 60 siemens and think racetronix is offering 79 pound high impedence just lately.

They may rate their gas different in Australia?? I would assume a person should run as high as locally available .We have 92 and 94 octane 10% ethanol and 91 octane normal gas here. The key is the alc injection system to run pump gas and still get decent timing and afr with a good safety margin.
