Can you post your GA16 dyno charts?

Can anyone post some for me?

Click the numbers in my sig, it's kinda big to post here.
EDIT: Eh, screw it, it's not as big as I thought.

It only goes up to 6,000 rpms since I'm just losing power anyway. And anyone have any idea what happened at ~4,200rpms?

EDIT: This is with a WAI, Pulley, Greddy SP Cat back, and advanced timing. i guess you can include the new clutch as helping too. ~$620 invested into the engine. That's less than some people's catbacks alone.

That was the VTEC, yo!

Ha ha... your horsepower and torque both have STDs

That's my little bitch!

My car never even made it to 100 and I have header installed.

I would post the dyno, but my scanner doesn't work.

Isnt about 4200 when the VTC engages or whatever..not sure why yours goes that way though..wierd

Yeah, it looks like it's retarding though.

Nobody else has a dyno?

I think I'll make a sticky in nissan vs. all for dyno charts / numbers and 1/4 mile track times so everyone can be included.

here's mine (keep in mind it's an auto):

97.4whp & 98.2lb/tq (thanks to some awkward spike in my powerband

)

what engages at 4200rpm?

himilefrontier · May 24th, 2003, 03:59 AM

I'd post one, but mine doesn't run yet!

VTC= Variable Timing Control (I believe). VTC adjusts the intake cam's timing to give the valves a bit of overlap in order to optimize the air flow at higher RPMs. Most Nissan engines at this time had this.

Newer Nissan engines now have CVTCS, which is Constant Variable Timing Control System. Rather than VTC (which is more of an on/off action), CVTCS is constantly changing the intake cam on a wider range of positions based on the throttle response.

just curious, where did you find all of this information. got any links? i never heard of VTC being on any ga16de or sr20de.

not really sure where tere's info, I mostly just happen to know most of thiss off the top of my head. I heard of the VTC being on the GA16DE and I'm pretty sure that if it is, then it would also be on the SR20DE (being that the SR is Nissans more "spoiled child"

)

The CVTCS is on the newer ones such as the 3.5L engine found in the 350Z, maxima, V6 altima, and G35. I'm pretty sure it's also on the QR25DE found in the new SE-R and the 4cyl Altima. Pretty much any Throttle-by-wire car.
