I currently running h2b with a 50mm xcessive manifold with vstacks my question is how many people are using vstacks in their manifold?? Wondering since the vstacks are so tall is that hurting performance??

 

Anyone

 

Can you call them to discuss? This is a VERY specific question no one else may have experience with. Do you have any pics for us to look at and grasp the situation?

 

Heres the pic. I'm asking if any other person who has bought a xcessive manifold has used the optional vstacks has had problems with it being so tall and close to the tb entry or anyone who did not buy the vstacks how the like the manifold. Plus I thought maybe a company wouldn't want to down play their product and say yeah there is problems with the manifold.

 

I don't have any experience, but when I look at that I see obstruction to the airway/airpath which will cause a ton of uneven flow. Thats my .02...I'm sure others may be able to say something else

 

Yeah gonna remove them and see what happens or try a 1" spacer to move the tb away from the vstacks.

 

i have a 58mm excessive h22 top mount throttle body with the velocity stacks and they dont interfere with the throttle body but its also a top mount. but i think there reason behind it is a venturi affect.

 

I have the center feed also which I dynoed both the side and center feed. Side feed was 74mm tb and the center feed was 90mm tb the center feed lost 10hp compared to the side. What size tb do u have on ur center feed?

 

im running a omni 68mm tb direct port nitrous on the bottom but im going to sell the whole set up excluding the nitrous
