I have a 01 L and my ported eaton locked up on me in the middle of nowhere. I drove it about 400 miles like this. It ran fine. But at over 3000 rpm it would kick into neutral. Just didnt have any power. 20 miles before the shop I lost even more power and the truck started running like cr@p. I put a stage 4 ported blower on "bran new".

Now if I hold the throttle steddy the truck kind of jolts as if I was playing with the throttle. It also does not have anywhere near the power it should and never accelerates smoothly. It seems worse at higher rpm's.

My mods:
Stage 2 heads (stock cams)
it 22's
magna flow ex
bassannie cats
6#lower
stage 4 ported eaton
stock upper
monster box
4.10's
SBTB
CAI
C&L plenum
predator

Please help me. What do I do? Thanks

 

If what your saying is that the locked up ported eaton is still on the truck, then your problem is simple. What happens is that when your rotors lock-up and you disconnect your blower belt, then your now naturally aspirated motor depends on the air it "pulls" in. This usually isn't a big problem with free-turning rotors, because they spin with the demands of the engine .But when they start to lock-up and don't continue to move, there is only the slightest amount of air being drawn in, barely enough to get the truck up to 40 mph. It gets worse with climbing rpm's.This happened to me. The answer is to pull off the blower , pull out the rotors and inspect where they are hitting. Most of the time your can lightly sand the area of contact until they spin freely by hand. I have also seen this remedy with other "seized" blowers.
My engine came back to life with no issues. If you don't feel comfy with this, then contact your porter and have him make good with another.Hope this long reply wasn't in vane!

 

Who did your blower porting

 

Yes that is what was happening.
The old blower is gone! I took it off and put on a bran new stage 4 ported eaton. I would like to see sombody make use of these rotors. I have pics of the new and old eatons "it's crazy".

I checked and replaced all plugs. They were the worst I have ever seen and one of my coil packs only had half a spring in the rubber gaskit. I streched out the spring to try and make contact with the plug. It runs slightly better. My predator now reads "ignition coil". That does mean the coil pack over the plug right? Once again thanks for any help!!!

 

Yes, it sounds like you have a bad coil pack(or two). Meanwhile have Steigmeir make good on your blower. My first blower was done by a novice board member(no names needed) and I had to have my machinest finish the job after the problem. Now it runs excellent.
