I was wondering when everybodys turbo kicks in.. Mine won't kick in untill 35 miles and hour when i step on it...

 

WOW!!! Mine spools up shortly after I romp on it.

 

I dont know about speed wise(mph reading), but it usally happens when the foot goes to the floor, it happens a sec or two after that.

I think you have a massive boost leak or exhaust leak. Is your mileage very poor?

 

I have a laggy 1.15 exhaust housing, but it starts to get going at about 10psi. Depending on speed 2200rpm is when it starts to light up.

 

My turbo is working all the time,,,,,,,,,. Anyhow, mine seems to really get going at around 2000rpm's. If you're not used to a turbo engine, they will do more when the engine rev's up. In other words, at 2000rpm's, you will have more boost than 1000rpm's. The more boost, the more power. I heard Gale Banks say that a diesel engine will gain 7% in horsepower for every 1 pound of boost pressure. There is always a little bit of lag time from when you hit the pedal and when the engine catches up with your foot.

 

Is it safe to assume you still have the stock turbo in there? IIRC, that took a little bit to get lit, but not much. 35mph . . . that makes me think leaks. The one I have now, it spins almost all the time. Pretty much any time not just idling, and it spools fast. It'll go nothing to pegged in about a second on the gauge, and even though its different, its not THAT different.
Do you have gauges or are you judging by ear?

 

Yes i do have gauges..When i stomp on it nothing happens till i reach 35 mph and than the turbo kicks in.. I barely can accelerate in traffic.. .HAHAHA....

 

I start to hear a little whistle every time I push past 2000 rpm.

 

What can you tell us about your truck? What year? What engine? How many miles? An exhaust leak around the turbo where the exhaust comes in to the turbo will cause them to not work properly. Also, a leak in the air induction system will cause them to not work right too. Are the bearings possibly going out in the turbo? Look for signs of oil between the turbo and the air to air cooler, and the exhaust.

 

it a 2000 f-250 crew cab short box with 237,000 miles and it has the 7.3 liter engine... ok i'll look and try that and see if there is any leaking around there...


thanks for your help guys

 

Possible air filter plugged up? Something blocking the air intake? Just throwing ideas out ther for you to check.

 

Mine starts spooling right away....probably 10 mph or less...not huge boost but it will hit 2-3 psi as soon as i press the pedal

 

I too gotta say it doesn't take much to get mine going. Just made a beer run in the 80e and it gets going pretty quick with moderate pedal input.

 

mine starts to spool @ around 2000 rpms and by 2100 rpms its on like donkey kong.

 

I just put my gauges in and this is my first PSD. Depending on how much throttle I give it I see 2 at little throttle and 18 when I stand on it. As far as whistle goes I have a loud whistle as soon as I give it a little throttle.
