Just got back form the dyno. All i can say is I LOVE IT... All i have right now is a lid, and a dynomouth exhaust(stock pipes, and tips), but anyways my numbers are:325.5 rwhp, and 339.2 rwtq... What do you guys think , pretty good for a nearly stock car??? I love LS1!!!

Stock except for the magnaflow muffler, but not for long!!!

 

Not bad.

 

Whoa. Those numbers seem really high. 325rwhp? You are telling me you are pushing around 385hp with just those 2 mods?

That's right in line with other '01 and '02 LS1's. I watched a bone-stock '01 WS6 M6 put down 327 RWHP! We had a '02 WS6 Collector's Edition dyno at the shop last week, and it put down 362 RWHP with FLP's with ORP, G2 lid and K&N filter, underdrive crank pulley, and Borla cat-back. The '01+ cars are STRONG! That's not to say that the '98-'00 LS1's aren't. My friend put down 350 RWHP with all of the bolt-ons with Macs and ORP way back in '99 when that was a feat! It's pretty amazing, especially when you get an "old-school" setup that dynos 300 RWHP with a huge hydraulic cam, ported heads, LT's, etc.

"Whoa. Those numbers seem really high. 325rwhp? You are telling me you are pushing around 385hp with just those 2 mods?"

the fbodys lose about 40hp through the driveline, not 60.
anyway i believe the numbers too, my 2000 put 318 down with nothing done, and i know the 01 and 02's are better. great #'s man. nice torque, the 01 & 02s seem to have a bunch more torque mine had 322
