Some of these trucks have more potential than others. I turned up a stock '93 at a dyno day on Sunday. It was stock except for a 16 cm turbine housing when I started. Bumped the timing about 1/4", put the AFC cone to the deep side, turned the fuel screw all the way in, and got rid of the high idle screw. Made sure it had full throttle travel, hotwired the KSB, and onto the dyno it went. 227/511! That's a healthy pump, an aftermarket fuel pin and a 3200 RPM spring should push it over 250 HP with the stock injectors.

Mine did a little better than last time. I disregarded the unhealthy clatter at idle and shoved the pump to the head. More timing makes my truck run better on the dyno, but it surges on the road set that way.

 

What'd your truck do Faith?

Wish i could have made it....Spring fling I'll be there when i have that little piece of laminated paper in my wallet [mad]

 

I have no clue what mine is making all I know is don't stomp on the skinny pedal unless your hanging on for a ride,and all I'v done is to tweak [ok maybe reconfigure that lil evil ve] pump

 

We had dyno days here on Sunday as well....My shift changed at the last minute and I couldn't go. Was planning on running old RAE on the rollers to get a base line. Guess I have to wait until April now....

 

the first time i hit the rollers i was bone stock excpt for pump mods!
and a good torque converter!
i made 260hp 604tq!!
theres alot to this pump tuning!!!

 

Man...I wish I knew about that dyno day...I'd like to see what my truck has to say.

 

my sons91.5 truck did 249/599 with just the pin turned and fuel turned up on an old pump on his first dyno run now that we have played with it more its doing 407/900
I wish my wife would let me see what my 90 will do ,But noooo, she wants to pay bills...what fun is that?

 

How much timing are you running? Skipped tooth and to the head?

 

Check out the PADTR Sub-forum sometime....we do plenty of events.

Nothing ever happens in Jersey don't bother going in there

 

Do you have the timing spacer in your pump Wanna?

 

That's how I dynoed it. For daily driving I back it down so the match marks line up. Sounds less spooky that way.

Not yet. I think I'll put one in for the spring dyno event and see what happens.

 

who cares spooky's good [i'll bet it makes your rig down right pants peeing]

 

I would be curious to see what happens with the timing spacer. Mine hated it with 1 tooth advanced. Works great with stock timing. But I tow. Never had it on a dyno.

 

my truck has 1 tooth plus the spacer and it really likes it. i wish the idle was a little quieter though

 

I am certain the difference is your injectors vs mine. Wana has injectors more similar to mine.
