PS. What do you guys think of NF octane booster

This is your problem.PapaJo wrote:You could consider changing gearbox with a gearbox with different ratios than your current gearbox. What code gearbox do you have installed now? Not sure where and when you change now on current gearbox over the 400m stretch. Close ratio box or a box with a longer 3rd gear might be the answer.
Hey Papa, I'm currently running a ffz gearbox. I change to 4th at about 350mPapaJo wrote: ↑Thu Jan 24, 2019 7:41 am You could consider changing gearbox with a gearbox with different ratios than your current gearbox.

Hi, the current box I'm using revs until 7800rpm but I make power until 5800.ICE King wrote: ↑Thu Jan 24, 2019 8:31 am Can go bigger cam but as you said don't want to loose bottom bottom end , can stroke the motor to aid the loss at the bottom.
another option would be a standalone management and tune for more power in the higher rev range and a higher rev limiter but then you need to log and twerk for optimum power , Stock heads are good for 7k rpm's , my bro had his stock head at 7.2k but dropped a valve
Headwork and you'll be able to rev higher but then you'll need supporting mods.
Thanks a lot. I thought that the ffz was perfect. I'll speak to a few guys here in CT. Thanks a lotmissioner wrote: ↑Thu Jan 24, 2019 9:53 amThis is your problem.PapaJo wrote:You could consider changing gearbox with a gearbox with different ratios than your current gearbox.

You have lots of traction and launch well and this is good.
Your motor is performing well and makes good torque, this is also good.
Where you are having a problem is you are not turning all that torque into top speed which why you get passed at +/- 350m mark.
Look into gear ratios and speak to some gearbox specialists in your area.
In the East Rand a good place to start is 8V Performance.
