spooling s469 for DD

I am not looking for full spool as much as cruising speed boost if I hit the go pedal it goes. I have thought about a smaller turbo bit I don't think a 66 would spool that much better


my 64/71/14 is fully spooled by around 1800-1900 rpms starts around 1500 i would guess a s300 66mm would be similar
 
ok just out of curiosity how much power do you think you make now? Brett just made 700+ with his 66/73/14 and says it spools better than his super b special(64/71/14).. im just curious why you think you need that big of a turbo? im thinking without doing a cam, something like 188/220 your not going to have anything much better than what you have now..
 
I think you need more displacement, about 6.7 liters ought to do it!

I agree with others, that is too big of a turbo for instant throttle response cruising down the road at almost zero load with 5.9 liters. I'd love to see you try a spool flange, and/or cam, new CAC, intake elbow, etc.... but I don't think you'll ever be satisfied if you'd like to see boost cruising at 1500 rpm.
 
I am working on putting together the parts to run a S472 83 .90ar t4 with a spool valve on the ole ladies 03.

It'll take a few weeks maybe more, but ill post up my results.

I know its not the same but its something.

Specs on it are:

4x4 QCSB
Drivetrain- 3.73 gears, 285/70/17 tires, auto with PCS controller.
Fuel- Floor-it 3.5, Flux 3's.
Engine- stock with studs.

Have not heard of anyone running a similar setup on a DD so we'll see how it goes.

A 188/220 will go in if i'm not happy with the results.
 
Cam, lower timing, spool valve, turbo blankets and port matching everything.

cliff its been a while, but what timing are you considering low. Are you thinking i am to high?
The blankets are actually getting ordered this week. That was already planned.

I am not looking for boost at 1500. I would just like more out of my current setup, maybe bring it on at 1900 consistantly rather then 2000. Looking for the small improvements, i am ok with lag it happens with bigger chargers.

The reason i run a 69 is plain and simple. I got a great deal on it, i am learning with it and will jump around trying this and that to make power. The truck will see multiple cams and turbos and pumps/ injectors. I am looking at building a 13mm right now just to see if the pressure and rate does what its said to. Its more for fun than anything. I would like to see 800 out of the on fuel and 900+ on spray. The lag dont bother me, i just am seeing what i can do to make it better.
Thanks so far!
 
cammit and you will never look back..
this is exactly why cams do make more power, if you tune around a cam you can use a bigger turbo and burn more fuel.. and on and on.. break more parts, spend more money, make more power, have more fun.. LOL you will get it one day..
 
Bring the timing down to 18* and set valves at .08/.16 see how that does. Next would be the 188 cam. I almost guarantee it would spool better, but I don't think its ever gonna get boogyin under 1850.
 
I run a s468 on mine ppump 24v 200-220 hamilton cam WITHOUT flycuts ported head ,and stainless diesel t4 manifold. I could cruise down the road at 1500 rpm with 2-3 lbs and 8-10 at 1800 rpm. Done with a 5spd at 30 deg timing.
 
Pierce so your saying your cam has the biggest impact on this?

Well i cant really say as i put a cam in and ported the head at the same time.. But as a whole those 2 things were the biggest impact. Before that it wouldnt start to come on until about 2200.

Now its fully lit by 2200 50lbs.
 
I run 18 degrees and set your valves at .008 intake and .015-.012 exhaust. The 12 will spool better but is slightly more risky

What pump was that done with. Factory air to air? Also was that factory pistons?
 
Those two changes plus the blankets should get you where you want, of not a cam (188/220 best option if money will allow it) or spool valve would be my next step. Then higher compression after that, then more displacement and if all that doesn't tickle your pickle... You will have an expensive boat anchor LOL
 
I run a similar setup on a common rail, when i switched to the 188/220 it made a huge difference. I would say 3 hundred rpms better for sure. Before the swap at 15-16 hundred rpms in od I could make like 5-6 psi, after the swap under the same conditions I can make 12-14 psi. The truck is fun to drive again, it is a 6.7 though displacement helps.

With a CDS 12mm 600cc that would do 5600RPM. Factory CAC and SO pistons.

Here is a poor quality vid of that setup. [ame="http://www.youtube.com/watch?v=TSNZnl_VsZE"]http://www.youtube.com/watch?v=TSNZnl_VsZE[/ame]
