I won't have them back for 2 wks so I will be installing them then. The topspeed and DC headers are basically the same so go with whatever is cheaper.

 

Hmm thanks fro that what if one is coated with jet hot and one isn't what do you think.

 

No noticable gains, but the jet-hot will definitley keep engine temps down.

 

I hear ya Im leaning toward the topspeeds im being offered becuase they are coated with jet hot. the dc's aren't

 

the name of the thread is "header and plenum-spacer dyno analysis" on 350zmotoring. its hydrazine's thread, and he has some great graphs in that thread.

 

not a member of that forum so it dosn't allow me to view links but I get the gist of it. If you can post the link here then I'll see it.

 

i suggest that you join that forum--its free--cuz sometimes this one is down for several days, and its nice to have another forum to view. Lots of the members here are over there, too.
Here's the graph, but there are other cool ones on that thread that are, frankly, beyond my understanding, but maybe you would understand them.

 

I want to but my company monitors our web activity and what we subscribe to. I'll do it from home

 

did you see the graph i added above?

 

Very Helpful by the way I have answered your PM.
