Import Tuner 370Z Tuning Article

ImportConvert · 11-14-2010, 08:37 AM

Just the other day I pulled up to a redlight. Feeling pretty cocky, even though I drive a 4-banger.

I looked left, looked right.

No cops in sight. Noone else really. I felt like showing out.

Then, out of NOWHERE! A dyno rolls up next to me in the other lane. I rolled down my window..."ITS ON! What'cha got for me?!". I thought I had it. Then it said "Bitch, I'm a MUSTANG dyno!"

I hung my head and slowly pulled away from the light when it turned green. I knew I didn't stand a chance in a race with a mustang dyno. Those always humble you.

Well, if the above could have happened, dyno-numbers might matter :P

A dyno is a tuning tool, not a comparison tool.

^Uh, I don't get it. No one tried to race or beat a dyno in the article. They didn't even compare the gains and conjecture it would beat any other cars. They simply used the 'tuning tool' to show how the car changed with various mods. Certainly there is discussion to be had about dyno type, etc etc. But the main thing I gleaned from the article is the relative gain from the exhaust and cats alone is the biggest. This may still hold true if it was cats and intake, but we won't know until someone tries it.

You really take the hardline with your opinions on here.

It kind of pisses me off my numbers are so low. I want to get on another dyno and see if it's the same, because it's getting really old seeing handfuls of cars putting down 320+whp with the same mods.

You can't compare dyno numbers with others unless you both go to the exact same dyno, all dyno's are different, even ones of the same brand have different calibrations. Mustang dyno's in particular all give low numbers while dyno dynamics give rather generous ones.

I doubt the intakes would yield the same result, when dyno'd separately I think their peak gain was 9hp. Stillen's own test results were much higher but I don't know how they got those numbers.

I put the intakes on first and gained 20 rwhp. When i put on the cats and exhaust it picked up 7 more rwhp. The pulley and headers added 5 rwhp. When i ajusted the fuel with my coob i picked up 9 rwhp,
Base line was 265. ( 7 at ) im now up to 308 SAE rwhp.
It depends what you put on first.
