I spent about 15-30 minutes on google searching for L67 and LS1 dynos, to no avail. They're either modded, or they don't show HP @ 3k (this is the info I really want), or they show bhp and not whp, etc.

Anyone have a nice graph? The one I need is LS1, but it would be nice to have the L67 also.
Thanks.

Well most stock LS1's dyno around 300 rwhp depending on the trabs, dyno, etc...

First, how do they get 300 rwhp when the bhp is 305-325?

Second, I need specs @ 3k - as in my OP.

Thanks

Can't help you with the 3k part, but the LS1 was underrated. They are closer to 350 fwhp

Dang! Thanks.

In that case, the chart I found might have been right. ~175rwhp @ 3k

All I got is a SLP lid and chokemaster catback, these are the numbers I put down:

The base line #'s were with SLP lid & muffler. Then the results of my 1 3/4" long tubes & ory install.

having had many of both L67 & LS1 with mild bolt ons I suspect based on seat of the pants that the L67 may make more power to the wheels below 3k after that is where the ls1 starts making its real power hence why everyone with an a4 car that is paying attention does a decent stall convertor as a first mod- they are kinda numb below 3k and beasts above 3k where the l67 due to its supercharger is making good power right off idle - both are great durable , easily moddable engines just different in the power delivery

LS1's can be anywhere from 290's to upper 320's depending on a lot of factors.
