starwheel adjustment
 

what should i adjust my starwheel to with a 0 plate in my pump i blocked my wastegate and cant seem to get any smoke down low only in od ive got bith the plate and wheel all the way forward or should i just gut the afc and does that have adverse affects

Not saying it's good or bad but, I have mine gutted with no problems so far.

which way did u go with the starwheel? Towards or away from the engine. I just recently took my fuelplate out but even with the 100 plate and starwheel adj it creates a big cloud. But the reason why it dont smoke in lower gears is cause its running to many rpms and its defueling. A govenor spring kit (gsk) will fix that though.

went towards the engine what does gutting the afc or running no plate do how bad does it kill the mileage i like goin 750 miles to a tank

if you sit there and put the star wheel full forward then your just dumping tooo much fuel.. all your doing is making the engine bog down, which means turbo lag. If you just tune the star wheel properly there will be less smoke and the turbo will light quicker. but thats just all from what ive learned

Are you sure you didn't also block the boost line going to the AFC? If that line is blocked it won't matter how loose you set the spring. I personally wouldn't gut it as the loss of drivability is not worth it. besides like ^ said if you dump too much fuel in too quick you actually make your truck SLOWER. Here is a pic to kind of give you an idea how this works.

on my truck i never blocked the wastgate even when i had the stock turbo. i just slaped a boost elbow right on the front of the turbo set it to where i wanted it , adjusted the star wheel to where i had a little bit more then enough fuel to spin make the turbo light and i was done with it. When i got my 64 on i put in the exhaust manifold, and the hx-40 style dp at the same time. all i had to do for that was adjust the wastegate because it came with an adjustable one. then i test drove it tuned the star wheel again to make the turbo light how i wanted it which means less smoke but thats due to quicker spool

i gutted my afc and took the plate out, im not too worried about it. bunch of smoke down low if u stomp on it but if u let the turbo keep up theres no smoke. also i have no elbow and i havent blocked it and i bury my boost gauge (30psi gauge, stops at 32psi ish)

I concur. My starwheel is still too far forward for my liking. Smoke every once in a while is okay (and when I want it to), but trying to merge into traffic and getting nothing but a slow-spooling turbo and a giant cloud of smoke is not what gives me my jollies.

Thats why i believe in tuning it instead of gutting it less smoke faster spool.

There's plenty of other things to do inside the pump besides turning the starwheel up for more "smoke", as well as power. Grind/slide the plate (which it looks like you've done), adjust the AFC lever for proper travel, grind the AFC foot/barrel, depending on what pump you have (160?), the 2095 mack plug.

If all you're looking for is smoke, plastic sacks over air filters work wonders.

i have the 180 but im not sure what you mean by grinding the foot? is there a certain profile or do you make it flat?

Bump... I have the same question.

It's just taking the taper off the foot itself. You can do that or grind the barrel of the AFC itself. Either one should net you a small gain in rack travel. This was one someone else did.

I studied the cutout of the afc but I can't remember that barrel or whatever its called

In my opinion, don't gut the AFC. Use it for a tuning tool and you will be a lot happier with your truck. Spend a day and take it apart study the thing, read about it, and just try different combos. Slide the plate back, adjust starwheel, fuel screw..etc etc.

what does a star wheel actually do?? And how does blocking the waste gate help?

so to get to the starwheel just take out the allen head plug and then rotate the wheel toward the motor how much should i move it

Im new here to the forums and have been reading up and researching quite a bit and now firmly believe a little knowledge is a dangerous thing. From what ive learned from yall off here i adjusted my fuel plate forward turned starwheel towards engine 25 clicks and ran it a week or so before returning to stock positions best i could now im left with what seems to be a common problem with newbies my truck lugs down preboost then takes off once boost kicks in any suggestions? And thanks in advance also any advice on timing advancement pros cons?

Alrite im guna try this again im new here to the forums and have been reading a researching quite a bit on my 97 12 valve 4x4 and have recently realized a little knowledge is a dangerous thing. I slid fuel plate forward afc and turned starwheel towards wngine 25 clicks ran that for a week or so then returned all to stock positions or so i thought maybe, now im left with what seems to be a common problem for newbies around here my truck lugs preboost then takes off once the boost kicks in any suggestions? An thanks in advance also timing advancement Pros cons?

25 clicks??? I ran mine up two clicks.
