EXHAUST QUESTIONS?

i have installed my 3" dp and i deleted my cat and muffler so i have the stock pipe straight out. it sounds great i love it, but will this affect my motor in anyway with no backpressure on it at all? i still have the valve behind the turbo. i just want to make sure i will not hurt my motor having no back pressure. also i got my guages installed and i was wondering if these are ok temps are they high? or low? or good?
trans temp on long rides runs about 130 to 150
egt is between 600 and 800

havent got to tow anything yet but i am going fishing this weekend so i will be towing the boat and see how they range then.

let me know what yall think.

are there any texas psd associations that anybody knows of?

temps sound good to me more people might know more. As far as backpressure its not a gas motor backpressure doesn't matter witha diesel you dont need backpressure backpressure cant acutally rob you of power.

Temps sound good. The upper end of the temp scale is 1200-1300 deg. It's ok if you reach these temps for very short periods of time, but that's it. So if you stay in the 600-800 range, you're golden.

Exactly. Diesel is very much not gas. Diesel motors don't need back pressure. So opening up the exhaust is great. Now the next step is to open up the intake, and let the motor breath easy.

yeah i have a huge intake from tymar and it flows extremely high

[cndrm]

Excellent. Duh, I probably should have read your sig line. Opening up the intake and exhaust on these motors is probably the best things you can do. Anything after that is just icing on the cake.

well i towed the boat to a fishing trip this weekend and my egt was around 1000 the wind was blowing 35 to 45 sustained straight in my face on the way out there and my trans was at about 180...does that sound right?

[cndrm]

I'll let some others chime in on the temps. I guess it would depend on the size/ weight of the boat being towed, but a 35-45mph head wind is a real b***h no matter wether you're towing or not. But, all in all, I'd say you're good. (but don't just take my word for it).

The turbo itself gives enough back-pressure

[bigp]

thats right the turbo kinda acts like a muffler in fact they make twin turbo set ups for vetts with no muffs just the turbos in the rear of the car as far as all diesels i think u need back pressure if u don't have a turbo

Everything you have said is good and normal.
