some of u kno that i recently got this truck...this is what i found under the hood..can someone explain if these are stock preformance or aftermarket that actually boost preformance

turbo is a garett?
in this pic there is also a bronze round looking thing..what does that do?



the k&n

 

figured its a wastegate..what does it exactly do

 

well I see a K&N intake on it. Does it help, some say it does. Most likely it is a reuseable air filter.

As for the turbo, the orginal may have been wore out. Garrett makes a good turbo.

 

the filter is reusable.. has something at the end of it...some kind of clear thing that lets u kno when u filter needs to be changed?

 

Air Restriction Gauge, you're right about letting you know when to clean the filter. There is a button on the end of it to reset it when you clean it.

 

ah i see..

 

I don't know if you have an early or late '99 (engine differences between the two). I know that the Garrett GTP38 is the stock turbo starting in late '99. Also, the wastegate is used to control boost pressure output from the turbo.

the clear restrictor gage is a stock item. It lets you know when the d/p gets too high (clogged filter) so that you can replace/clean the filter. Your diesel sucks a LOT of air and I would recommend a dry filter of some sort. If it is a K&N, IMHO I would replace it. it does not filter very well and your engine will suck out the oil and ingest it. I had an aFe for a bit, but I couldn't keep it clean. Coupled with the fact that the OEM air box doesn't seal well, I went the way of the "6637" mod like many others (do a search on it and you will have more info than you ever wanted about it).

 

10 4.. i just need one question answered.. i wanna kno about how many hp i am seeing..

with that turbo, the banks from the engine back, and the k&n..about how much?

 

I think the '99 came with 235Hp and around 500lb-ft of torque. The K&N wil help a little and so will the Banks. Banks is not known for being a very cost effective, bang-for-the-buck, mod for the Powerstroke (at least for the 7.3L), which is why you'll see very few people with anything Banks in their signature. My '03 has 250Hp and 525lb-ft of torque, and I would guesstimate that you are somewhere around there as well...

Just my .02

 

I'm no diesel guru by any means but the gains posted above seem about right. If you're really looking to open up that 7.3 and get those 42's rolling, get a programmer (and gauges to monitor egt/boost/etc).

 

thanks. those are definitly coming soon. the banks came with the truck so im not complaining lol
