| | 408 truck dyno
I dynoed 408rwhp@5700 and 436rwtq@4200. I know they look low but, it had 24 degress timing , 4.10s, truck intake, through Flowmasters, and spinning 85lb 20s. The torque curve is FLAT, it makes 430 at 3600 and still makes 400@5800. I need a bigger camshaft, it is a 230/230@112+4.
On a 200 shot with pump gas, it made 580rwhp and 677rwtq. I am very happy with the nitrous numbers. It still has the lean spike but, it is getting better. I will install a fuel cell in the very near future.
The A/F ratio is off alittle from the street tuning I did. On the street it is 12.7 and on the dyno it is 12.3, I guess the dyno can't load the motor like 4500lbs can.
What do ya'll think?
