Gday. I have recently suffered low power in my 2.8 rodeo. The injectors are only 40 000kms old and the IP was rebuilt 5000kms ago. The power was fine after the IP was rebuilt but has since lost some power. I have changed the fuel and air filters and blew out a blockage in the fuel tank breather which hasnt made a difference. I also jacked up all 4 tyres and spun them and none of them are dragging. The car idles fine and will run all day, just low on power. I dont have a boost gauge so I cant check the turbo boost but I can hear it spooling up. The engine doesnt have any other mods apart from a catch can and a 296 CAV style filter instead of the standard type. Any ideas what it could be?
Cheers

Check the pipe on the top of the pump to where it joins the intercooler or inlet pipe. I had that pipe split and performance went very flat despite still having good boost. That pipe sends a boost signal to the pump and if the pump doesnt recieve it it supplies less fuel

Thanks geeves. Yesterday i also noticed mine also had a small split right at the end. I replaced it but they didnt have the right size hose. The hose i bought is slightly too big could that make a difference? Also maybe the hose clamps arent quite sealing it properly?

It doesnt take a lot of leakage to mess it up There are several things it could be

I will check it out. Can you think of anything else it could be?

Restriction in air intake ie filter etc
restriction in exhaust ie cold start device stuck on damage etc blocked muffler
timing moved
tappets loose
wastegate stuck open
turbo not free spinning
loss compression
blocked fuel filter blocked vent in fuel tank
etc

Ok thanks geeves. Will try work it out
