What is this nonsense...
I personally made 625whp at 4700ft altitude in 2005. 150zex wet shot, 2.8" pulley, full bolt ons, throttle body heat exchanger etc, stock long block. 485~whp off the bottle.
It was good for 130mph trapspeeds up here. 4.10's were holding it back on that combo. I think it would have done 133-135 with 3.73's because I had to boil way high to like 6500rpm+ to avoid needing 5th gear. My power peaked and fell off with that combo from 5200rpm. I had a window switch and bottle heater. Combo worked very well.
On the street, shifting at 5,500-6,000 it was seriously fast for the times. In 2005, 600whp was still fast/uncommon. Surprised c6 z06's, gt500's, on and on and on with that combo.
Went a little over 10-15,000 miles and 2 years on that combo but I got bad nitrous on one of the tank fills and lost cylinder 8 in 2007.
Bottom line is I made close to 650whp eaton/nitrous. It did get hot/heat soak, but if you run alcohol or methanol injection, you could probably cool the iat's by 50-100* pretty easily.
I'd imagine a ported eaton at about 525whp coupled with a 150shot would be a beast with a little meth injection. E85 would be even cooler (literally and figuratively)
Parts I didn't have on that combo that could only benefit a sprayton car. (spray+eaton were sprayton's iirc; god the nostalgic nicknames take me back a decade):
-headers (I just had stock logs with 2.5" catless dr gas x and 2.5" magnaflow cb)
-cams (a stage 2 blower cam would do wonders)
-head work (500whp and up, the stock heads 230cfm intake flow can be improved on for slight to moderate gains from what I've seen. From 750whp+, a full 300cfm+ port job can bet 50whp+ done well)
-standalone management (if you are trying for records/class racing/etc where every little edge makes a difference. a stand alone like a Big Stuff 3 will probably find 5-8% more power even at those levels than the stock ecu can allow. Mind you the stock ecu is pretty usable. I'm still on mine but might switch this summer)
-proper fuel system (I just had boost a pump, 60lbs injectors, etc) (good fuel with a great ecu would probably be good for a combined 10-12% power gain vs stock ecu/boost a pump/60's IMO- it's all tuning so a great tune may shrink the difference to nothing at all but as an average, it's much easier to make power with a nice fuel system and open ecu)
-cooling system (I just had an afco heat exchanger, stock fan, radiator, et al) (helps a ton with iat's and consistancy. Meth injection could be huge, that or e85 fuel... Lots of potential for efficiency when 91-93octane gets curbed for higher efficiency sources)
-oil mods (factory pan, pump, etc) (reliability, safety. No real power gains but it's smart money.)
