When is your beast going to be through? I've been reading and hearing about your car. Whats the update?

There is a guy im Miami , Tony. He is making over 790 on boost alone.
He ran a 10.1 @ 140 on drag radials on low boost.
This is Jeff Burke from Canada. The white Mr2 from the highway video.
This is Davin Lashbrook from Arizona. He is also making 750+. This is his old setup with 2bar t78 and a 100juice. He has went with a better motor and turbo combo. He is making 700+ on boost now.

This is MIke Colon from florida. He is making also 750+ with a low boost nitrous combo. Running low 10s in the 140s with traction problems.

oh ya and mr2s are sweet but too small for my tastes.

MR2s are alright i suppose, IMO if something runs 10s it doesnt matter how it does it, so long as it does it correct? Its the whole "whats it feel like on the street" factor that sets a RACE car aside from a STREET car, how do those 2 crazyly HP Mr2s drive on the street?...they do drive ont he street right?

Basicly, if you have a turbo blowing 200 degree intake air temps, you could have 10psi and not be flowing any more air because the density is crap. Remember pressure (or boost) does not equal flow. Flow is mass over time (lbs/min). Pressure is mass over area (lbs/in^2 or PSI). Hot air has more volume than dense cool air, and that volume in a fixed amount of space creates pressure (PSI). So 50lbs of cool air will create less pressure than 40lbs of hot air. The car with 40lbs/min of hot air flow will have higher boost PSI than the one with 50lbs of dense cool air flow. The 50lb of flow point in the cars rev range will make more power with the less boost on the same car and turbo. Flow determines power, not pressure.
So, that Viper with the turbo from a 1L might have 10 psi of boost at 6000rpm, yet be flowing less than if it was NA at 6000. This is due to the fact that that tiny turbo is heating the crap out the intake air and spining way out of spec rpm ranges to generate that pressure, while sacrificing flow and thus power. That heated air will cause the Viper to knock and pull ignition timing as well, which kills power. So you have less air mass being pumped, less ignition timing, all while dealing with an exsaust restriction. The Viper made its peak power on that weak turbo a long way back in the rev range and it was dissapointing, no matter if its still got boost. This is why turbo systems are so tuning sensitive. Its also a big part of why turbo choice depends of rpm range as much as displacement.
Cliffs Notes:
Pressure is not flow.
Flow determines power more or less. More flow=more power in the same setup.
Inefficent tiny turbo heats air up and creates pressure, while losing flow.
Losing flow means losing power, even with boost pressure in the intake mani.
Thus the Viper would make more power NA than with tiny turbo, even if tiny turbo is making boost.
Intake heat sucks.
Mods:
Should I repost this in FI? I'm sorry I hijacked this a bit, but its great info for guys going to FI.

I didn't know a CRX could go 9 seconds with a full weight street legal car. I saw a video, it did. Then I found out the engine was pretty much out of a fighter jet (twin engine style). In my opinion if any car can go 9 seconds or has 600-700 hp it really isn't the original car anymore (I'm talking inline 4's here).
Hell when you hear about people with 427 iron blocks or resleeved LS1's and 12 bolt rears it isn't a real Camaro (or LS1) anymore.
Anyway long story short MR2's don't make 600 hp the engine that the guy made a downpayment for a house to build makes 600 hp. Then they had to replace the transmission etc etc etc.

Me on the other hand has spent less than 20,000 on my deuce and is quite capable of a mid to high 10 sec pass. Yes this might sound pricey, but I choose quality parts and didn't skip out on anything. Or I could have taken the cheaper route and saved 5-6000.
Gt 40r turbo-1600
fullrace manifold(ex)-1200
downpipe-400
exhaust-1500
built longblock-6000
clutch-2000
standalone-2000
fuel system-1000
tuning and install 2500
And yes it still has ac and is driven 3-4 times a week.
