If someone can explain this, pls. do so... I don't have any racing vocabularies.

If you want anything more - you need a custom ECU and heavy mods to handle it. Mine goes to 7800...but look a the sig...

everyone is saying that max HP is achieved at 6600 rpm or 6200, i dont feel like going back to look, but do you think your max HP is around 7800 or is still back at 6600?

sorry i skipped most of the posts but with some otehrs i ask why?
for this to be effective i think you would need forged pistons, maybe some other internals and im pretty sure to make it effective at 7500 u would need new racings cams and a place to tune your ECU to optimize performance with these parts

My car is a different story - it' all built up...it Can handle it and does it well. It make power through 7600...

but to get power out of it you'll need different intake and exhaust cams with the right lift and duration for that RPM Range (6,000rpm-7,500)
Our stock rods will probably be safe (if you have the rev up motor) other then that.. if ur using a non-rev up motor i wouldnt bother..

i have an 06 6mt and mine cuts me at 7200.i dont know about u guys but i feel the powwer all the way to 7100.!!! yes i do think the sweet spot is close to 5500-7200.the car unleashes at this point and flat out hauls *** all the way to 7100 which is where i shift at when im getting down with someone.!!
i do believe that if you dont shift untill 7100 u will lose power since the rpms will be lower in the rpm band..besides if you are running someone that can keep up with you and has a little bit of power you will lose everytime if you dont give it your all and the cars all..after all these 05-06 cars that has a rev up motor..makes the power up top mostly..the non rev up motors have globbs of torque at the jump but if your racing a non rev motor u will beat him every time stock for stock up on the top end..!!! thats why they already have the spacer in the non rev motors..and the rev motors have less torque...!!! IMO

Difference between "revup" motors and non-revup motors:
The revup motors have stronger rods and a different cams. It also has variable valve timing on the exhaust cam as well as the intake. It also has a different intake manifold and ECU. The intake manifold is what makes the power difference..
Because the car revs up higher it can utilize larger runners allowing it to achieve higher horse power.. but because of the bigger runners air velocity is lost at low rpm causing the motor to loose low end torque. in return the motor has a very smooth and steady power band.. if anyone of u have dyno ur car you'll notice a nice straight line..

Forge pistons and rods maybe new crank? prolly a bigger oil pan to allow atleast another quart of oil....
any ideas?

Easy answer to your question, direct from the source, including my original email to them below:
"We raise the Rev 500rpm more on Rev up motor.
On top of what we do with Non-Rev up motor menu, we also change exhaust cam timing to gain bottom end torque.
There is not much gain at top end on Rev up motor, since it is already squeezing pretty much all the power it can make, but we can gain good amount of torque at bottom end to mid range.
