car made 471whp 604rwtq on a land and sea dyno yesterday, no changes since ltxtech dyno day. either the trans is slipping or something with converter. owner of shop said it is a 600whp all day car if it would actually read right and not spin/flash converter on dyno

gotta get it to the track.

the torque number is off though, been reading about how it's reading and I think taking 50 off the torque and adding it to hp is logical due to the converter

the motor naturally aspirated made 490/490 on engine dyno with smaller heads, so motor is making probably 510 crank hp WITHOUT boost. add 10-12psig to that number and the converter/trans are soaking alot up

I'd be more interested to see what it does at the track than on a dyno

we are, hence the rear upgrade. also, it's gonna get a new procharger Inlet too to get rid of the plastic restrictive one, I've been reading alot about that being a choke point in these cars. technically, it should go low 11's high 10's with a good driver and traction
