Yeah, it looks like it starts around 5250 RPMs...

They didnt underate this engine at all, spoon is right. why would they underrate an engine that has had sooo much popularity. if anything i could see them overstating the engine to produce more sales, but spoon proved that they didnt. I like the engine. and im sure it wont be long before somone goes and puts a custom header with a t3/t4 w/30PSI...HP tuners needs to catch up to the tuning on that thing too. I am definately trading in this RL for that RL...(like 5 years from now)...

The torque is damn sure underrated... 250 wtq = 275-285 crank...

228 whp = ~260 crank...

So the motor is putting out 260/275... I'll take 'er...

There will definetly be something that you want more by then.. like maybe the new 2012 500hp+ Z98 Camaro!

Huh? What's a twin screw?

Kenne Bell or Whipple... I think he ment "twin scroll"

I knew what one was, I was just trying to figure out what he meant...

I got up close and personal with the Sky Redline yesterday... the techs say it's as fast as it's supposed to be...

LSD
Billstein Coilvers

mmmmm....

Fuck the t3/t4, get a turbo that's good for road race/drag..

Gt30R or GT35R or B16G

Also, please note the dip in hp/torque near redline, must be were she's bleeding boost. I'd think another 10hp is there for the taking in stock form...

I'm thinking the turbo is too small to sustain max boost at the upper rpms and thats why its dropping. Same thing on the srt's.

That's a good point... even though power starts to climb after the dip though? That distinct lil trough right at 5200 looks like something opening...

Even if the power does drop off, it seems to have it when it really counts. I'd bet they have nice 1/4 mile runs with a curve like that. Even if they don't have that great of a top speed, there's no denying their acceleration. 0-60 in - what was it? Around 5.5 seconds? - is mighty respectable for a 4-cylinder. Mustang GT's have a freaking V-8 and can do 0-60 in around 4.9 seconds.
