New dyno numbers.. got a quick question.

[03cobracoupe]

Here is a dyno graph directly comparing two different setups.

The setup in red is a diablo chip, bassani catback and catted x-pipe, and upr cai and a 3.10 pulley.

The one in blue is the same thing except for a richer chip and a 2.80 pulley.

Tell me why i lost hp with the 2,80 pulley? Its not slippin i dont think. I think its probaly cause the richer chip, but just take a look at the graph. A few more interesting things are i did pick up 15 rw torque. And if u notice on the graph the blue is making more power than the red until about 5500RPM. Why would this be? Sorry for all the questions.. Im just kinda confused...thanks

Here it is

The richer is tune looks very good to me. Also, it looks like the 2nd run (with the 2.8) made more horsepower thru most of the r[m band range... the only time the previous run did better was at the very top end. I believe you have a great dyno here. You have the additional power where it really counts.... and a safe tune

:beer:

I'm no dyno guru, but it looks like you have a 20rwhp advantage through 99% of the rpm range and the other chart got you on the absolute peak.

Definitely a much safer tune with the 2.8, I wouldn't doubt it if your getting some belt slip.

What were your torque numbers?

The 2.80" should make gobs more torque than the 3.10"

Got a graph of the TQ curve?
