Iv'e got a 1994 Auto EF XR8.
Stock motor,Megasquirt and spark ECU,Genie headers into a 2 1/2 IN Lukey exhaust and Lukey highflow muffler and K&N pod Filter. It's making 130 RWKW.
Just wondering if this a good or bad power figure for what she is.

I think it should be making more then that. I think a stock 6 cyl EF-EL makes like 95-100rwkw

Hard to say, chassis dynos are very hard to judge.
Can give a really rough idea if you post the chart up, or let me know what type of dyno, what mode etc.

130 is pretty good for those mods. It took a lot more than that for me to make similar power when i first got mine.

Thats about right for a relatively stock 5.0HO.

Thats seems about right, for those mods.
I pulled 126rwkw, with Genie's, exhaust, and a pod setup (which was s**t).
But mine is manual
So 130rwkw in an auto with those mods is about right, or in the ballpark anyway.

Blimey, thats alright. A stock series 1 AU XR8 auto is lucky to crack 140rwkw. 130 is s a pretty good start. Imagine what a little strategic porting will achieve combined with you current mods :wink:

Also the difference between a dirty MAF sensor and a clean one.
Some say its the oil from K&N filters and the like.

Its a very good figure considering it is a 170kw motor brand new. Given the drive train loss it is a good figure indeed.
