Sadly, most dynojets have weather stations that read poorly or wrong and they cannot be corrected. I see especially low humidity reporting with the DJ weather stations and this can really skew numbers lower on a hot muggy day. If the actual conditions are 29.96 baro, 65% humidity, and 96 degrees F, but the weather station reports 29.98 baro, 19% humidity, and 89 degrees F, you're going to get a low dyno number. I see it every day. People will literally throw strong running combos in the dumpster because some stupid weather station was reporting wrong conditions and wound up making the dyno run lower than it should have been.
For the OP sake I hope this is what it is.
Before you change anything i would first compression test all 8 cylinders,then do a leak down on all 8,Or have someone do it for you.If it checks out OK,then change intake and go from there.I would not be as concerned about the dyno # as i would be about it having a problem somewhere.You do not have all of the available boltons,that are hurting your # also. TSP, I run your heads on my car with good results,MY OPINION,Now why dont you guys help out the opening poster,instead of worring about one, YOUR OPINION comment?Chris uncle has all the latest engine building equiptment also,been building motors for 30years.He sees bad parts all the time.He has a ROTTLER #8
There was a huge storm just south of there the day I was up there and got rained on as soon as I left cook county. I think 26% humidity is probably whats doin it then. It was hot and damn muggy for that kind of humidity. But I'm no meteorolgist lol
