View Full Version : New Turbo for the PSD - Quickspool

March 31st, 2005, 10:26 PM
The new one is much larger than stock.

Notice the curved blades and the two tone? It's more noticable that the fins have erroded when you look at it and touch it.
The exhaust turbine has much more volume than stock. No backpressure valve either. Or wastegate.
The outlet is huge too compared to stock.

I can't believe how big the inlet is! Notice the compressor bolt missing just to the right of the WG selenoid? The whole compressor housing shifted.

QSSB is the model. (QuicksSpoolSwitzerBell?)

Here are the billet intakes. Notice the small inlet on the stock plenum. :rolleyes:

I'm thinking this PSD is going to breath.

Eric and I finished up the install last night and went for a test drive. I'm not sure what my impression is yet. I had to stretch (temporary) my Banks exhaust to mount up to the dp and the clamp let go soon enough.. It's free and noisy now. I used to like flutter.

I'm a little dissapointed that the air inlet tube doesnt fit right. I had to remove the whole airbox/bat box. Luckily I had the early 99 bat tray still and put that back in so I could mount the air filter. It contacts the brake booster with the filter and goes really close to the intercooler tube. It seems too short. I'm not sure what I will do about it.

I put the 140hp DP-Tuner program on the chip and took it out for a test drive. I'm not used to running the 140hp so it's not much of a test. It got up to 1400 still. The 120HP program got up around 1250. The 40 and 80 stopped at 1200. I was expecting lower egt's than this. Coming to a stop it's about 400. After waiting for a car to pass it rose to 425. :shrug:

The boost builds pretty quick compared to stock. It also hit 28psi fairly easily. It wanted to go more but stopped pretty fast. I should be able to hook up the scanner to see what the MAP is seeing. I have a reg. on it but havn't checked it lately. Maybe it's defueling...

Between the exhaust leak, the new turbo sound, and my natural paranoia I seem to think that there could be a boost leak. One thing at a time I guess. A little seat time should help too.

Here are some pics:


Today I had a chance to work on the truck again. Using my shop press and a Dana 60 carrier bearing I was able to flare a piece of 3.5 inch pipe to make a coupler. It worked pretty slick. So now that the exhaust was fixed I do seem to have a boost leak at 27 PSI. I starts to make a noise and the boost holds holds there... I know it wants to go higher.

I was thinking about the EGT's and feel better about it. I remember when I got the DP-Tuner and tried the 140HP program it rocketed to 1600 degrees. Today it was holding below 1400. I guess that's a pretty good improvement.

I ordered a Wix filter today like the Tymer deal. I'm going to try to try to build a SS intake tube so the filter will fit perfectly. As you can tell from the pic the Hypermax tube is way off...

This things seems to spool pretty quick. :wink: And the truck is faster than before as I really have to pay attention when driving. The smoke is reduced but still plenty...

I'm pretty happy with the new turbo and look forward to seeing how other's EGTs may line up with mine. I have a few minor tweaks that I want to make to the mounting and various revisions of things but at least it's on the road again... I was getting too limber climbing in and out the of Jeep for the last two weeks.

QSSB = quick spooling sum' bitch maybe? :flipoff2:

Are you still running the stock injectors Dave? I can't remember.

Sum-Bitch... .that's pretty good! ;)

Yup, stockers. It runs pretty good with them. It'll be a while before I upgrade... Are you going to the dyno meet on the 16th?

I called WOP this morning and asked. You're right! haha And the ASB stands for Awesome sum' bitch He also told me that the intake tube was made for a stock airbox. Who has one of the those? :rolleyes:

I picked up a huge Wix filter this morning. They had some 4 inch 90's so I should have a new intake tube fabbed up this weekend. :beer:

YOU do, from two different model years, and it didn't fit either of them. Their intake tube is just wrong.

I'd like to go to the dyno meet.

It would be interesting to see how your truck would run with bigger injectors and a newer (99.5+) HPOP.

Eric, I do have the top of a stock airbox but we didnt even try it. The AFE kit that we tried pops on top of the bottom half in place of the top half. It's spaced over and apparently the stock rubber tube stretches to mate up to the AFE.

CSP, I already have the newer HPOP. Mine was pretty sad. I have a gauge/line/fittings if you want to test yours. :) Bigger injectors would be a kick. However the new power should last me at least until summer. haha

Well after cleaning the air filter and fixing some boost leaks it can hold right above 1200 on the 140HP program unloaded. I towed yesterday with the 120HP program and stayed right around 1200. A time or two it would go up to almost 1300 and stay. Maybe this has to do with airflow through the intercooler or something... It's still goodness as I had plenty of power and didnt really have to watch the gauges. I could hit 1600 easy everytime with the old DI 80HP and 100HP programs.

So have you noticed any real kick in the pants or just cooler temps? I would hope that really got the truck moving. Whats the goin cost for the new turbo setup?

Both, couple hundered degrees cooler and it scoots much quicker now.
