Let the modding begin!

Posi ports work well.The mono blade T-body is a worthy investment.We have seen 15 RWHP with that alone,after a lower,CAI,upper and tune.Any resriction removed before the blower nets big gains on Positive Displacement Blowers.But again your gonna be in the 90+ % duty cycles.I know lots of people are getting by,but do you want to be the one that does not?This is just food for thought... I tend to be very conservative,I have seen bad things happen when enegines lean out.

Cobradoc,

I wonder if I told Jon Lund about all these mods, if he could account for it in a tune? Or are you saying it is a physical restriction of the stock fuel delivery system?

Physical

It becomes a capacity thing.The stock fuel system will work,but you have to realize that you are at the ragged edge of what you have.So you will need to stay on top of things.Meaning frequent filter changes and paying attention to how it runs,when your running it hard.If it does anything odd,get out of it and investigate.If you a system matched to the power level,it is much more forgiving.Fuel is king in making power for the long term.Lean is not a good thing in boosted applications.I personnally do not like box tunes,as I have witnessed first hand cars that are modded exactly the same,taking totally different tunes.Like I said,I tend to be conservative especially with customer cars.I would rather leave power on the table,than hurt and engine for 25 - 30 horse that you probably can't put to the ground anyway.
