365/431 on stock manifolds...



What are the limitations of stock manifolds?

 

thats with the nitrous right?

 

I think the highest horsepower guys are the STS turbo guys with stock manifolds going up to 500rwhp

 

With the nitrous and low bottle pressure.... someone said something about being limited around 375 with the stock manifolds, just wanted to see who was making what.



By the end of next month I should be around 360-370ish N/A though.

 

I'm going to try to get to a dyno next week and be hopping to be around 410hp/500tq on the bottle. And then next month to be around 520hp/650tq on the bottle.

 

why dont you just get longtubes........Your losing some serious horsepower with those restrictive things......no sense in doing all those other mods then to have stock manifolds.
