Limitations of pump gas - highest HP on pump gas
346ci,9.5-1 comp, F1 supercharger-18lbs,93 octain(no addidtive)- 780hp/590tq for daily driving.
346,9.5-1,D1 supercharger-14lbs,93 octain(no additive) =690hp/580tq, daily drove for 20k miles and raced once a week.
Pur Evl car -408ci,Turbo-15lbs,93 octain(no additive) =820hp/790tq -still driving,no problems.
So,think 600rwhp can be done on straight pump gas? Absolutely, with no Meth or additives.
Also,why is there alway's "I know this high power this-that" in these threads?
The guy just wants to know if he can make 600rwhp,not who has the biggest dreams

I think most of these guys running big numbers on small cubes have larger, more efficient turbos, and a very efficient charge cooling setup. The numbers on pump gas would drop like a rock without those factors both being top notch.

Oppps. It's easy to get carried away, though. Isn't it?

on a stock motor i would stay away from 600+ 93 only no meth if you don't have cash to spare for another engine at any time.

I missed that part too All that high hp crap threw me off 
For a stock block I like the hp at 500-550rw for longivity.Some people will pull a 600+rwhp dyno # for boasting but ussually turn the tune down for engine life

Limitations of pump gas I'm just curious... what is the limit of the power you can get out of an LS1 with FI on pump gas? Here are the restrictions:
1) No spray.
2) No changing stock cubes.
3) 93 octane only.
Changing the SCR, DCR, cam, heads, forged internals, high RPMs, etc, etc is still fair game. What would be a rough maximum power output with this setup?
The reason I'm curious is because I see a lot of FI cars on the boards putting out hundreds and hundreds of HP, but I'm not sure which of these can actually maintain the power they put down on the dyno and which have to fill with race gas and/or spray to get the numbers.

I never did any dyno runs on my 346 at all..
But I did with my current 382, and on pump gas only, I made 735 rwhp and 666rwtq on a Dynapack hub dyno.
I could ahve made more, but they dyno was having issues, so that run was with quite safe timing, as increasing the timing made the dyno go nuts.

Why do you see so many people driving n/a motors ???
Everyones personal choice.
Not everyone wants the expense of running a high power motor, and all the hassles that can go with it.
Some people just want a mild increase in power, that is totally reliable, and reasonably safe for every day use.

Peak dyno numbers are not the only thing to look at, you can build a peaky combo that hits 800rwhp or higher but that never hits the track and probably would not run anything impressive. Look at how few folks in this forum run over 140mph.... even 135mph.
I'm looking to hit 800rwhp or higher and run 152 mph or faster.

i got a good question that dosent really pertain to this thread though, how come a supra with 3.4 liters (i think) can easily hit 800 to the wheels and we cant easily double that?

2. they are willing to use a 150 shot to spool the turbo (they can't spool a gt47-88 without it)
3. they are willing to rev the motor upto almost 10,000 rpms to have a usable power band once they do spool the turbo.
4. most of the way over sized turbo cars are just race cars even if they claim to be "street" cars.
5. the big power guys also run th400's with BIG converters which really helps spool the turbo as well.
6. 3.0 liter supras don't make 600+ rwhp on 91 octane like 5.7 liter and 6.0 liter LS1s do.

Think about the question...Lets face it, how many people would actually want to double it.
Do you think running a car with 1600rwhp is a realistic prospect ? Of course if can be done though.

I went up to ~860 rwhp on pump... felt taht was plenty.
