Default how do you raise redline.?

Seriously i want to get my red-line up to at least 8000 rpms. i see Hondas and other cars that have a red-line of 9000 after they mod it. So what do i need to do in order to raise my red-line and ratio(if possible.)

Rebuild the motor and install stiffer valve springs.

The only way to do this without causing any catastrophic problems is to put in bigger head bolts or head studs, to allow more clamping force to mount the head to the engine block. Also stiffer valve springs to eliminate valve float, change ECU programming, Balance and blueprint the engine as well, and you should be able to get up to 3-4000 RPM Higher.

chip out your ECU. the tuner would then be able to adjust your redline and vtec engagement accordingly.

Are you wanting to raise the actual redline, or just the rev limiter? My 02 rsx-s has a rev limiter stock at 8200, but kpro would move it up to 8600. If you're just wanting to move the rev limiter up then all you need is some ecu work.

the NUMBER ONE engine trait that allows high revs is balancing. minute differences in the weights of moving parts will lead to failure at high rpm, which is why lower-tolerance motors have lower redlines. rpm's cost money, so be prepared.a simple chip will bump you up a little, but a drastic increase in rpm's will need a fully balanced and blueprinted engine with super-stiff springs, first class connecting hardware, and the tuning know-how to feed it all properly.

you can raise redline using Kpro, Hondata, or any other tuning softwareBUTlike stated, you will need stiffer valve springs, forged valves, better cams, basically completely build the head, and then it probably would hurt to build the bottom end too since thats gonna be working harder

pretty much alot of people are dumb cuz every motor comes stock blueprinted....you can rebalance and reblueprint but every motor is already done....better valves/valve springs chip your ecu at a tune shop...
