Floor it I feel kind of bad for asking this but just how much SMOKE are you produce

ing with this bad boy on the differnt settings!!

 

[Floor It]

The smoke is affected more by the TQ# setting than HP setting. With the HP at #6 and TQ at #4 there was some smoke not HUGE! IMO but there was enough there that another diesel guy would know that you were turned up in the power. The power from this (per) smoke compared to the ISB 24v smoke, this is less smoke for the same amount of power.

They started shipping these things last week. Surely by now there are a couple other people with this great electronic marvel installed. Any body else got anything to say?

Some perspectives ... think about it

With regard to the stock turbo, let's put a couple things into perspective. . .



With a factory rating now of 325hp, the stock 3rd Gen turbo is close to its practical limits in terms of efficiency with STOCK horsepower. It has a terrible, RESTRICTIVE 9 or 10cm exhaust housing which causes exhaust drive pressures to skyrocket (leading to high EGTs and reduced efficiency).



Back just 2-3 model years ago when stock power was "only" 235, 245hp, by the time many guys cranked their power to where our STOCK levels today, they were upgrading their turbos. And the stock turbos on 2nd Gen 24 valves flowed BETTER than what we have now



Running your boost past about 32-35psi is completely useless. In fact probably counterproductive. Why? You're turned your turbo into a massive heatgun, pumping searing hot air into your engine. Doesn't exactly let you exact maximum performance from your engine, does it? Yeah boost skyrockets because of all the power you have, but the better you do keeping it from going above 35psi the better off you are.



Just some "points to ponder. "

I agree but with this box your going to have a hard time doing that. Even on the lowest settings you can get to 35lbs plus. The turbo is going to have to be changed to really get any use with it. This goes the same for the other duration and timing boxes that come out too. this turbo is just too small!

So what if you get a bigger turbo housing for the 03 . What size would you get? Will the internal pieces of the stock turbo fit in a bigger houseing. thanks rhino 50

Floor it - LOL is that the point? To impress other 'diesel guys'? =]

And would the Banks Monster Exhaust still fit? I wondered about this before I ordered the Banks system. We will see.

Ken F - take a look at DPP, they have a 4" stainless system for sale now. I just got one, they are sweet. Full 4" downpipe too, but connects to the stock turbo v-clamp.

As for new turbo's would one of those modified stockers work well?



I have a turbo mount pacbrake, are there any better turbo's that would work with that?

 

[SRadke]

The new B1 for the 03 is suppose to be a direct bolt in with a stock truck. If this is true it should work with the Pacbrake. My only fear is lack of clearance around the exhaust housing for the arm that the air cylinder is mounted to.

Joe Donneley spoke of this issue in another thread. I forgot the exact number but a 9cm housing equated to like a 1. 5" exhaust. I have however heard some conflicting info via Mark Chappel concerning some surprisingly low drive pressures when running at high boost with the stock turbo but I thought DD found pressures to be high. Is it possible that the larger outlet of this new turbo relieves some of the backpressure? TST said in the past that it really didn't do much good to change out the exhaust since the restriction was in the exhaust housing. Unfortunately there are no larger housings available for the stock one.



Aren't you running the PDR modded turbo Vaughn? Has that shown positive results? I know Joe was less than optimistic about modding the stock turbo due to the small housing issue and there was some debate on the other thread.



I wish Holset hadn't cast that dern 90* elbow into the compressor housing. Is there a new B1 I'm unaware of? I'm looking at one of the 4" inline brakes.

I almost went that route. I changed my mind at the last minute because the Banks system gets rid of the cast iron elbow and provides a true 4" directly from the turbo. My thinking was less restriction would yeild lower temps. I don't have the system yet. It should be here Monday. Hopefully I will have it on by the weekend.

 

[Blakers]

Does anyone make a larger exhaust housing that will fit on our stock turbos yet? I had a 16 cm2 non-waste gated housing on my 95 and that was nice.

 

[Floor It]

The quick spool B1 for the 03's is bolt on, and uses the stock elbow so if you have an exhaust brake it should fit. Piers has a modified stock turbo for the 03's but I dont think it will help alot with this box, but I'm not sure until testing is done.

LightmanE300, I dont understand what you mean by impress other diesel guys?

No big deal just poking a little fun at you in response to your comment "The smoke is affected more by the TQ# setting than HP setting. With the HP at #6 and TQ at #4 there was some smoke not HUGE! IMO but there was enough there that another diesel guy would know that you were turned up in the power. "

Yes I think the Piers modified stock turbo would help, but, with the power gains of the TST box it's not the best/final answer. It only addresses the compressor side not the exhaust housing. Basically you buy some more wiggleroom by having cooler air going to your engine's intake (I am assuming this is how the turbo reduces EGTs 150F or so). But you still have high drive pressures and trying to force all that HP out a little housing.



Like I mentioned in other threads the Piers modded 3G turbo is a good idea from basically stock to a mild box where you want to buy yourself some more wiggle room without a large outlay of cash, but, it's not the best answer if you want to "do it right" in which case go with any other turbo available with considerably larger exhaust housings like the Quadzilla, Qwikspool, PDR40, DD Jammer, Bell USB, etc.

Who makes the B1 quick spool?
