8whp more with just a K&N intake and cutting the divider in the box? That seems very high for a filter replacement. Obviously you had to purchase an aftermarket ECU, or VAFC which can range from $300-$1000 am I correct?

 

NO bs, just with a filter swap and modd stock box=8whp. i would have been skeptical myself, but thats the truth. when i did this swap, it was done while the car is on the dyno. the tuner was impressed himself! the vafc came later on. i did all my modd checks at the same dyno to get somewhat cosistant readings.

 

Wow thats impressive!
where was the HP gain in the RPM range?

 

around 5grand on up. when ever we meet up i'll show you dyno charts on all my modds. next modd is going to be a intake thermal gasket.

 

awesome!
I look forward to seeing these dyno charts

 

When you say gutted what exactly did you do? I have the top off of mine, a k&n filter, and the center column removed.

 

I cut the center baffle out and cut a 2.5 inch hole in the end(passenger side).when i dynoed mine during the filter swap, we also did a run with the lid off and lost 4hp! also removed the elbow on the lid. i love dynos. sure way to find what works and what does'nt work.

 

How much do all these dyno runs cost?

 

a good friend of mine owns his own shop. i get good deals 40$ a session. he has a dyno dynamics dyno. the name of his shop is import hot rod garage. he has a web site.

 

I have never dyno'd a car before (The car owner gave me the dyno charts from the mods), but im guessing a session is 1 run?

Sorry for the dumb question i just dont know
