Timing Advance Spacer...

[Richie O]

I have an appt on Monday to dyno my truck, Tuesday or Wednesday I will be putting the spacer in and hopefully dyno it again after its in. With my mods anyone care to venture a guess on what I will make for numbers?

When you do switch the spacer make sure you leave the rest alone. So far all I have read is people that installed the spacer and done other mods at the same time. They say they have made more power but most may have come from other mods done during the swap.

I say 245 for an auto or 280 for a stick.

Truck is a 5spd and I have done all the mods I have the money for until well after the spacer is installed. It would already be in but it was requested that I do my pin and 366 spring before I do the spacer just so we can have some numbers.

Any advice on dos and donts for the dyno?

[Richie O]

Is your timing stock now? Is whats in you sig everything that you have done? KSB hotwired, stuff like that? I still say 265 to 280. Also what type of dyno is it. Some don't load the truck well. No load = lower power ratings.

My sig is all thats done that I know of, stock lift pump, turbo, injectors etc. I added the 4" exhaust the pump was turned up some before I got it but I cranked it up the rest the way. Star wheel is down about 3 turns, smoke screw in abit. Timing, KSB and all that is stock as far as I know.

I dont know what kind of dyno they have, all I know is its CHEAP to use, Im paying $45 for 4 pulls, my thought on it is simple, use the same dyno and while the numbers will be different on a different dyno it should show changes in power from mods, so this will be my "baseline" to go from.

What tire pressure is going to be best, I have 33x12.50x16 TRUXUS on it, am I better off running the tires to the max?

I'd say bump the timing a little and also run it in 5th on the dyno, I agree with Richie as far as HP guesses.

Thats what the timing spacer does for me It allows for more overall timing while keeping stock base timing

You are correct and I am interested in your results. Should get some true data on the spacer.

Well dyno results are humbling I dyno'd in 5th gear and made 200hp and 375ft pd tq. I have another appt on Friday to dyno after I put in the timing spacer. I will port results then.

What are your boost and egt #'s on the street? What type of dyno did you use? Was your gauge readings as high as on the street? ( I mean did it feel or sound like it loaded the engine )

I'm so excited!!!

Boost hits about 27 - 30 psi and egt's hit 1300 or so. I actually didnt look at them I was trying to watch everything else, it did sound like it loaded the motor but not as much as I thought it would have. I have a couple theorys on whats going on with it. First I very well may be running out of fuel as I have the stock lift pump and my full power screw is maxed, also I do not build as much boost in 5th as I do in 4th about 5 - 7 psi different. I am also not sure what my 33x12.50 do to the dyno numbers.

The dyno is a dynamics brand I think it said........

Probably not to bad for stock IC injectors. Those things really choke the power. On the flip side they are also putting lots of stress on your pump since it is maxed.

[Richie O]

At our dyno day I saw a 93 with a rag put down 270 ish hp on a maxed setup with stock sticks. But he had done every cheap mod that he could. Timing, exhaust, intake, afc, ect.

[lectro_static]

my game plan is next will be timing spacer, then cold air, lift pump, turbo then new injectors. I hope that with those mods I will be where I want to be but who knows.......
