well I origanly had the keg on my 408 and it ran pretty good as you can see from my pic and video on the bottom of my posts. then I switched to the air gap, performace seemed to go down but I was battling several other small problems. Well I got it all sorted out and performace was still down. I used a widebant o2 to get the fuel perfect and had my tuner send my map to hughes and the hughes tunner that does all the tunes related to the airgap said my tune was good and he would not change a thing. But perfomace was still down I babyed it for a complete tank of gas and got 13.08 mpg.
So now I changed back to the kegg last week without any tuning changes to work with the keggs needs and got 13.24 mpg and I raced a new camaro during that week( beat him to the next stoplight by a truck length!)
My observations. The kegg is much stronger in overdrive while crusing. The kegg is much stronger up to 2750 rpm then the airgap starts to take over. A truck is a truck and you want low rpm and thats what the kegg gives you. With an intake that makes it power higher you will always be turning higher rpm and I want to make my motor last. these are my findings bact to back with my stroker motor tuned for the airgap your results may be different on a stock motor.

 

You have to make up the bottom with gearing.

 

hp/tq estimate?

 

Muscle motors (who designed my cam) built a carb version of my motor with a slightly bigger cam for a give-a-way and it had 500/500 so I bet I am around 450/450

Make it up with gearing! I want to be able to sell things the way they can! "Ummm yeah if you buy our 600 intake you will have to spend another400-800 parts only to re gear your truck for the low end you will lose"

 

wanna sell the air gap?

 

Yeah seriously pm me bout that air gap. i got dibs. but were you using a stock keg with the plate or a keg with the runners cut and plate?

 

The only thing I did to the kegger was open up the tb intake holes on the top to match my 53mm tb. (besides the plate)

I have one guy that asked long ago I believe about it that gets the first shot at it then it will be in order of the people asking in this thread.

 

whats the stock bore for the kegger?

 

i would really like it for my 360 build so pm me asap if its available

 

I am talking to one person that asked a long time ago. If I am mistaken I am sorry to anyone who may have been first in line. If this does not work out I will work my way down this tread.
