Well, I FINALLY got around to timing the car today, a couple of questions.

1. When you are shooting the light at the crank, do you aim straight down from directly above the pin? Or at an angle? The n_dahi site said "Aim the timing light so as the timing light, the pin (pointer) above the crank pulley, and the marks on the crank pulley are in a straight line. " So I assumed this meant aiming the light from directly above.

2. Should you notive an instant difference in HP? From following the steps on the website and aiming the timing light fromstraight above the pin and crank pulley, my car was set at ~12-13*. I moved to to ~17-18, took it for a spin and did not feel a gain. Am I doing something wrong.

Help!

TIA

um well yeah you should notice a instant difference but what you do is drive it around for a week like that and then move the timing back down and then tell me if you notice a difference.
:cool: if you then dont notice a difference I would say you might have done sometihng wrong.

what gas are you running. if you advance your timing past 17 or 18 degrees, you should run premium 93 octane fuel. otherwise, it might not be as effective, but that varies from car to car. i've heard of people running 89 or evey 87 with 19 degrees advanced timing.
btw, it doesn't matter how you point your timing gun. light is light, and you're not looking for the shadow of the timing needle. but i would suggest that when you look, you look from the top down, atho, the needle is pretty close to the crank so it shouldn't make a difference.

I advanced my timing about a week ago I dont think I noticed any real improvements either but then again Im in the stupid mountains in Albuquerque NM. I have never even been to any real mountains until I got here. 17 degrees of timing is right below the 2 marks that are close together right?:confused:

the marks on the pully go like this
0* 5* 10* 13* white paint mark 15* 20*
if your just past the 15* mark by the width of teh needle your on 17 pritty much.

Alright when I advanced my timing the car was idling at about 1000 rpms after I unplugged the the TPS. I just saw a little while ago that you need to rev the car 3 times so I will try that and let you knwo what happens.

i have had good results with 21 degrees base ignition timing and 91 octane gas

Ok Ok i see lots and lots of people talking about timing, but exactly what WOULD happen if someone advanced their timing WITHOUT a light? Can you blow a piston? Will your car run like shit? Will you fry the engine? These are some of the questions we need..lol So exactly what IS the procedure on adjusting the timing?

Over advanced timing will lead to detonation. Detonation will ultimately lead to engine failure.

Ditto. Well I use 92 octane but I've done some ghetto timing tests with a friend's NX before.

We both started out at 15 degrees timing and raced. Dead even (we had similar mods).

Bumped his timing to 17 degrees. Still dead even.

Bumped my timing to 21 degrees (vs his 17). I pulled on him 2 carlengths by middle of 3rd gear. We repeated these results consistently.

Sleepin 91ser makes a good suggestion. Drive around with your new timing setting and in a week or so back the timing back down to where it was before. Then you'll notice the difference! It's much easier to feel a loss of power than a gain.
