I believe they were talking about the exhaust gases.

I understood that I'm saying his exhaust exits at the front of the truck but our trucks are not designed to cut through air and airflow underneath wasn't a big thought of the designers. The airflow patterns down there are going to be sparatic to the point his cut out will be fine and he woudln't see any changes if he pointed in more rearward.

 

have you thought about modifying the brakes, larger rotors and pads something that will hold up more?
Line lock?

 

Thats what I was thinking. A trans break would fix all of the launch problems.

Also, You have a built motor with a very large turbo on stock heads?!

 

the high cost of heads puts them at the bottom of the list of things to do. the stock 6.0 heads are prety good. i have done lots of reading on this subject and the concensus is with the t76 heads would have done prety much nothing for me. with the 88 they will give me the same power at a lower boost level or more power at the same boost level but may not add much to my peek hp once i crank the turbo all the way up.

i will be geting heads eventualy, it is just hard to drop $2k+ on something i am not 100% sure will kick ***. if i start lifting the stock heads then it will be an easy decision since aftermarket heads should stay down better.

 

wouldnt a bigger stall in the range of 3500 eliminate the boost buildup problem at launch?

 

do you need a 2 step if you have a transbrake?

would the tranny be able to hold back 1000+ft/lb's without something leting go?

bigger brakes might help and not be a bad thing to have on the truck. i might look into that.

 

Red, I simply meant the way his piping was done in that with the cutout closed there waqsn't a smooth bend for the exhaust to flow through. It will hit the end end piece of pipe and then flow through the main tubing. Now once it has air flowing through it it could very well create a "wall" of ciruclating air that will redirect the main airflow but I just didn't know. ultimately like myself and Jim stated it really shouldn't matter mcu because when you really want 100% power the cutout will be open and there is no turbulance there since it's a straight shot.

 

i think it would help a ton.

there are a few ways to work this lack of boost problem.

nitrous, easy and i have it now.

transbrake if they make one

bigger brakes

bigger stall



for now i think the nitrous would be fine especialy for the track but i want my street launch to be strong and not have to spray everytime.

 

You are making so much power do you think your getting to the point of limited returns
I mean aerodynamically have you thought about diffusers something to help push the air around the truck on the underside or a small spoiler for added traction
I would think your starting to approach the limits where those factors become increaingly more important and power is less important.

Just some thoughts, might help get you into the single digits.
