However there are losses in efficiency to design conditions. For instance my little "neon" has a 2.4 with a very long stroke so it actually loses efficiency as opposed to if the stroke was shortened.

You got an email I can send you the enthalpy charts and diagrams of what happens when air is heated and "cooled" relative terms since everything contains btu's no matter what our ºF or ºC say. It won't let me post links.
I also have a site that tells you the exact way to choose the right compressor for your motor. However I do disagree CFM is CFM and lbs/hr change with the temp/altitude/grains of moisture

If the turbo is matched perfectly to the motor you should be able to floor it and get no fluttering sounds and no surge. hard to do but it's possible if you know about psychromterics and how air works.

It's all about lb/hr when dealing with forced induction the size of the motor makes no difference except in the pressure the internals see for that given cfm.

What we don't know are the exact conditions these races are being held under.
In the end of course a T67 will make more power. It moves more lb/hr than the 3076 at almost 50% more lbs/hr.
My guess (and it's just that cause there isn't enough info) would be both (no matter what psi) were moving very close to the same amount of air but the srt-4 weighs less. I bet if both were dynoed under those conditions one after another they would both be making close to the same wheel power.

Plus with water meth you get the added effect of steam cleaning your internal when it's on. It practically removes all carbon buildup after the spray nozel.

Meth has an extremely high octane level. Water and meth is mixed at time because the specific heat of water is one of the highest know. Meaning it takes more btu's than other substance to gain 1 ºF for 1 lb of the substance. For example standard air takes .24btu's per lb and water takes 1btu per/lb per ºF.
So in retrospect water absorbs heat from the combustion gas better and meth adds octane level. The two combine work out great.
The term octane refers to pre ignition. The higher the number the slower the fuel will burn. This is a major advantage on turbo cars because adding pressure alone to a air fuel mixture wants to start the ignition process.
Even with higher octane fuel the exhaust gases will be higher than when using meth.

Psi is just a number. Look at the vol. the motor/turbo moves and you'll know the amount of power it makes.
Saying 15 psi on this 2.4 is better/worse than 17 psi on this 3.0. It all means nothing without knowing the volume of air the turbo moves, air temp and air to fuel ratio. Thats why horsepower numbers are given and not pressure in relation to how fast a car is.
230 horsepower in a 2900lb in most circumstance would be faster than that same 230 hp on a 3400lb car.

I like the nozzle that purges through the rams nostrils. But that's sweet.

I noticed but what does that matter? It has MPH in the big numbers and KMH in the smaller number so the car only has 60980 miles on it. Just curious.

I wish we had an no speed limit highway...that would be fun.

with slicks I would probably agree. Would have to ask the owner about that. But since he isn't launching at 2500 I think the answer is obvious.

The first nitrous pass was at 3000 also.

wopps.....unless he is under 70% throttle. Then boost wont matter I think it limits boost in first gear anyways. Kinda hard to keep any fwd car from spinning 1st and 2nd with 400 HP.

@ 2500 he would still be at full spool with a stage 3 turbo.
