Good figures if they're accurate mate

 

Thanks mate, I've held off going to dyno as I thought I would wait until Ive decatted the car and changed intercooler.

 

will I be better putting standard ported headers on?? what power these good for?

 

Not at your level, it may be a step backwards. There may be better tubular headers than yours though. Ported headers can be restrictive at about 450.

 

To be honest richsc said they dont use them after the 380 mark as become choked up....

 

From experience there's nothing wrong with Kakumei headers! Exactly the same as gt spec headers...

 

Running GT spec headers and a SC46 on my 2.0 and getting 429/380

I'm looking into building a 2.5 bottom end to up the torque

 

Hi Craig

Speak with John@Braveheart developments about the his headers,he run his ported headers in high 400' without the issue

Kakumei are same as GT Spec headers and there is no difference,just I wouldn't use cheap headers on yours


Thanks,Jura
