How much power do you think is safe on stock internals?

RCZ · 05-22-2011, 12:09 PM

Hey guys, just taking a poll to see what people think is safe and what isn't. If you would like to add why and under what circumstances, that would be appreciated. Keep it civil please.

Also, lets talk dynojet numbers so we can all be on the same page and since both GTM and Stillen use them.

I'd say 500 if you don't drive it like you stole it.

A.J@CarbonSignal · 05-22-2011, 12:31 PM

450whp if you drive it hard and 500whp if you barely get on it. Of course keeping in mind tune is spot on

Blue370tt · 05-22-2011, 12:48 PM

FYI for those voting 450 whp.....most of us TT guys have been running around with more than that for over a year.

The dyno photo in my photos was after my first tune and no longer accurate. I have been closer to 500 whp for over 6 months.

Stock power

Brazilbro · 05-22-2011, 12:57 PM

I voted 600whp because I was voting for how much hp it would take to blow the bottom end

G37sHKS · 05-22-2011, 01:36 PM

Guys you need to realize something, if stock can handle 600 HP that doesnt mean that we can go for that route.. comn, give the engine a break...

500 WHP is idle.. anything more than that you are risking it...

450 "safe level" but there a lot a variables as altitude , temp, driving habits, plus some motors are stronger than others

Q8y_drifter · 05-22-2011, 04:54 PM

I'd say around 450whp with a generous margin of error (by that i mean atmosphere, driving style, etc.)

Nismo370 · 05-22-2011, 04:54 PM

500whp is the safe limit for these motors I personally think. Remember these motors arent like the older 350Z's motors where they make a lot of torque. Remember its the torque that destroys the motors not the power.

NewYorkJon34 · 05-22-2011, 05:39 PM

The Z runs an 11:0:1 compression ratio which is not the best for forced induction of any kind. I know there are many Z owners driving around with 450-500whp but the real question is "for how long?" I personality will be upgrading to the GTM stage 1 shortblock, and will feel much more comfortable about driving my car. I'm shooting for alil over 550whp.

m4a1mustang · 05-22-2011, 05:55 PM

I'm a little on the conservative side and say 400whp is truly "safe." But the question is definitely a little vague as the definition of "safe" is really open to interpretation.

RCZ · 05-22-2011, 06:08 PM

Where you dont have to worry about flogging it because you think its on the verge of letting go.

This true as we are all saying what we have read, have been told or just what we "think" is safe. Only thing that is forsure is that time will tell what the safe level actually is.
