Just put in some of Weston's 7mm comp dv's and good lord what a difference in low end smoke!! They smoke less than the 181's and feel much stronger.

Ill have to ask him about that. wonder if you did something else at the same time? usually big DVs means more smoke and heat right?
 
i already have a set of his 7mm's that arent his biggest but the 100cc's over 181's on their way.. ill let you know how they work out for sure.
 
Let me clarify; Cliff, you have the 100cc version as I thought they suited your application better than the Comp style, the same thing Adam is getting. Brian, you have the set smaller than the 100cc version which I hope to have flow results on tomorrow.

Now, back to the thread at hand.

any updates cliff? I might have to get me a set if you like them. I need to try something.
 
Wasn't able to get a full run in but they are lower on egt's by a little bit and seem to spool the charger better, Ill run her hard tomorrow.

Good to know, their still a lot for me. I'm happy as ever with them.
 
I will have a set of the ones Bsmith is running soon to compare agains the current 7mm full comp cut delivery valves i'm running presently. Should be interesting given i've had nothing but good luck with these 7mm comps.
 
here is a video that shows taking off normal to 5 psi, then up to 20 at the end.. if you cant tell what i dont like.. i dont know what to say..
maybe just remember this is the best it has been maybe half what it started like..
181's and 62mm now..

Your .200 to .300 numbers seem unrealistic, what where your stock head numbers? 200cfm at .200" is crazy. What else was done to the head?

Sorry, this is a 24V head and valve size may be different than yours(6.7).
