cool... what setup do you have?

Running FR2's and Fidanza Cam Gears..... LOVE IT!

Here is the dyno sheet, let me know what ya think....

 

[03OrangeSVT]

Not bad... but I think there is still more power to be had.

 

[silveib]

remember as well that this is on 91 octane
noe you say more power is to be had, how so? what would they do (so i can get them to do it properly if i do go back)

 

[03OrangeSVT]

You start with the exhaust cam, get in dialed in (usually 1 or 2* increments until you see no more power gain) the exhaust is usually somewhere around -4*

Then start tuning the intake, same process it shouldnt take more than an hour to do.

 

[silveib]

so the rest of the tuning is simple dialing out the cam gears.... what if i went to the track on a test and tune night and just played with it like that till i got the fastest time?.... i realize that there are alot of other variables but i bet i could get it close. I would be scared however that i might do damage to the motor by running it hard at a setting it shouldnt really be at...
another thing, as kind of a convention i assume that the smoother the idle and overall operation at a given setting, the more power its probably making... of course given all other things equal. Does this make sense

 

[turbovation]

I don't think a smooth idle necessarily means more power at all...a lot of people with cams dialed in report that they have to raise their idle because it is too choppy down low...could just be motor mounts though.

 

[besthaticouldo]

honestly i miss that idle

yes it makes sense that tuning the cam gears changed the idle...it changes how the cams are timed which changes the idle.

you might be making more power and making the car run better. it will also change the tone of the exhaust i imagine. i know adjusting mine did.

good luck dude.

 

[silveib]

what do you guys think of the old school track tuning technique?

 

[silveib]

so i gave her a decent stretch today (at -4-1) and it pulls significantly better..... hopfully with a little more tuning it will get worked out

 

[03OrangeSVT]

I've been told that somewhere around -4 intake -6 exhaust does best... but I dialed in a friends with a compression tester (going for max cylinder pressure) and it was something like +4, -4.... but we have no idea what cams he has (junkyard motor)

 

[silveib]

ah so they can be dialed in with a compression tester.... that is a good alternative seeing how my friend is a mechanic.... sweet

 

[iminhell]

You can not judge power based on idle quality. Like stated earlier the cams will have a range that they work best in. That range is partly dictated by the opening times of the cam in relation to crank angle, and that relationship changes the intake air speed. Generally at idle with a decent cam there is low air speed and low vacuum (you can crudely use one to judge the other). It's also in part the the amount of overlap. Generally a larger cam will have more overlap, which will effect idle quality. All these things are related.
There is a really good site Harvey Crane put together that you may want to search out and look through. I can't recall what it is off hand and don't have time to search right now.

 

[SquirrelZX3]

you could run it down the track on a test and tune night to dial it in. a friend of mine uses that method on his renegade class mustang he usually does this at every track he goes to during the season so that he can be dialed perfect for the local track conditions cause maryland dyno conditions are never teh same as florida track conditions or any other track conditions. he will usually have his settings done within 3-4 passes. and this is a car that runs in the 7s consistantly and needs to be setup for whatever area he is racing that weekend. driving the car while adjusting shouldn't hurt anything cause if yuo feel the car isn't making any power when you start off just let out of it and cruise back to the garage and readjust. hopefully this helps you some.

 

[silveib]

thanks guys..... looks like i am gunna take it to the track!

 

[1turbofocus]

You CAN NOT set cam gears going to the track and making passes even if you made 100 of them a night , dont waste your time or money

^^^ Agreed . You can get it close by driving it to what "feels" the best. That will hold you till you get to a dyno. But, you really need a dyno to finish dialing them in and getting the tune correct.
