Would it be safe to rev to 8500 on a stock b16 head with I/H/E, chipped ecu, and itr cams?

 

the first gen b16's have dual valvespings on one side only. the sirII's have dual all over. doing 8500 on the first gen is pushing it. i wouldnt. i personally am going to buy some ITR springs and retainers when i get my CTR cams

 

I have a stock b16 cylinder head.
Stock redline: 8200
Redline with JDM b16 ecu: 9000
My car goes 9g's fine.
What year is your b16?

 

8500 isnt that much over but personally id like to be safe. 9000 is really pushing it on a 1st gen b16 head tho. i would just invest in some ITR springs they are cheap and will do the job fine. furthermore they are not overly stiff.

 

I don't have a 1st gen b16 head...check my sig, y0!

 

you won't make power past 8200...

its stupid to rev higher with stock springs...

Not in my case...JDM ecu has completely different fuel maps, and DOES make power up to 9000 rpms.

 

oh yeah?

is it a magical ECU?

i disagree

reving higher will result in a higher RPM when you shift gears, which will leave you in a more powerful band of power.

Though doesnt matter how magical your ECU is, you wont be making power at past 8k w/ ITR cams.

rev her to 8500
