Go to this website

and punch in 317HP and 5200RPM and click calc
You can see the comparisons for a Dyno Jet and for Calculated Crank HP.
I'll take (434-330=104) 104 Crank HP gain for with just a pulley, tune, iridium plugs and a SL55 intake....(under $2K list - and I paid even less..) and 373WHP for a Dyno-Jet Dyno.
Diffrent dynos, different conditions. To bad this website does not list all the dynos.
That's a good link. I can only speak of Dyno Jet numbers. That's the only Dyno near me. Mine made 288 WHP with K&Ns when stock. That was reading SAE, Smoothing 5. It's common knowledge that NeedsWings Intake put out WHP in the 320s on a Dyno Jet. Granted, it would seem that a Dyno Jet reads Higher, but most tuners seem to believe in them over Mustang and Dynapacks.
Given that experience, I would guess mine should be putting out around 330-335 on a Dyno Jet at this point.
If you do the math, there is NO way CHI-TOWN is outting down 298. Horse Power Calculators that take into account vehicle weight, ET, MPH, 60 Foot etc. Put CHI's car in the 370-380 WHP range. At 20% drivetrain loss a Stock one should put down 280. Therefore, it's my belief that Pulleys, ECU and Intake will put down ALOT more than 298. Personally, I think MD's car should put down a little more on a Dyno Jet.
Based on a Dyno Jet Dyno, I still think 400+WHP without the bottle isn't too far fetched.
