KwikKurt KwikSpool w 12cm housing = Holy Cow!

[KatDiesel]

All I can said is oh my god that thing rocks. I haven't even gotten into overdrive with it yet. The thing moves... ... . NOW my truck drives like it "supposed to" I have damn near rearended a few people because once the boost is built it stays!



No other real reports yet... getting dark and its only 50°



All I can say is WOW I am beyond impressed. FLoor It, belive it or not I think its quicker now. Your not gonna believe this... ... ...

What about the PDR turbo??

KatDiesel,

Since you've moved on to a "bigger and better" turbo, what do you plan on doing with the PDR turbo? Hint, hint... .

You have no use for it right?

Folks, I have met Kurt on a few occasions and all I can say is "this guy has desire". I talked with his dad in Tulare and made a comment to him about his son. He grinned and said "Kurt has been like this since he was little, he used to take anything that we had that was broke, tare it apart and hand it back to us and say YOU DON'T HAVE TO BUY A NEW ONE, THIS ONE WORKS GREAT!". His dad was sooooo proud of him and that made me feel special because you now, my dad would be proud of me right now!!!



Kurt is top notch and if he has something to offer then by god open your ears and at least see what it is, it will probably benefit the enhancement of your truck.

I got to second that, Peter, Kurt goes at it 150%, I don't think I saw him take a break, the whole time we were in Tulare.

Was great to get to meet him out there, he's a great guy, and I know for a fact that he's really good to do business with, no matter what.

So how do I get one Kat???

 

[Don M]

I ran out of time today or I would have put mine on too.

Kat, you must have gotten in on the same batch as me.



I have a 12 valve so the results may vary...



I will post tomorrow after I get it on.



I had to do the governor springs and top secret cam plate today.

4000 rpm is no problem at all.

Super Kurt

Kat, Kurt is due in here at my place tomorrow. I'll be happy to relay your kind remarks to him.



Greystoke, If you are looking for one of Kurt's turbos, I might be able to help you out. I think he has a spare with him. If you are ready to make a purchase then send me a email. I'll search his truck to see if he has any spare turbos ready for adoption

Since Kurt is going to HVAC's... quickest way would be talk to them. I have no idea if he has any left. All I know is I have mine and damn happy with it and I haven't even gotten out of 3rd gear yet with it.



I have been asked TWICE now at stoplights tonight if I had a supercharger under the hood. The turbo SOUNDS cool as well as performing well. Its more then I was expecting to be honest.



I am real anxious to get to the track Sunday.



HVAC -



Tell him I am all smiles and still smiling, and thats only been on Level II and III on my COMP! Too much traffic to truely test it out. Needless to say I am very very very happy with the outcome of it.

Cool!

I'll be happy to relay that sentiment to him. I have no doubt that he will appreciate your kind words.



On Saturday Kurt and I have tenatively planned to tour the Military Vehicle Technology Foundation collection of armoured fighting vehicles. You can access their website at www.milvehtechfound.com



They also have a light gauge railway for those of you that don't like to steer

HX-40 12cm Kwikspool

It's a wonderful thing

So Who's turbo spools up quicker???

Running BD2'S VA and DTT 91% VB & TC the low boost smoke is there.



Which turbo would be better for control over low boost smoke??



Is there much diffference between the 2 using a 12cm housing?



My truck also pulls a 30' 10K 5er this is why I see a problem down the road. Right now EGT's are no problem with the HY35 9cm turbo. The HY35 spools up very quick.



Thanks,

Bob



EDIT** Is there still a demo unit making the rounds??

First off bare in mind I was running my PDR turbo well above what Piers recommended, on a lower powered truck it MIGHT be a different story.



Well smoke control I can't really say, if I don't want smoke I turn down the "smoke" setting on the the COMP. Even with the KwiKurt when I want to I can make smoke..... but it goes away pretty quick. I would say KwikKurt's turbo beats the PDR in this department. Difference, yes KwikKurt's is unreal, the truck never stops pulling until I am at the engine govnor, once it spools it likes to keep going I think it spools faster then my PDR did.



Even if there was a demo unit around I don't know who would take it off their truck once its on... ... I would imagine t hey bought it on the spot, I would have. Only reason my KwikKurt will come off is A) I blow it up, B) The B1 is even better when Kurt releaseses it.



Temp comparisions I can't really do because of the air temp is low now vs when I had my PDR, wouldn't be a fair comparision. Plus haven't gotten out on the highway yet... or out of traffic to really hammer it.



As for everyone asking bout my PDR turbo - No its not for sell for a couple of reasons. I have no way of being fair as to who I sell it too. I have a list of about 30 names inquiring about it, sure I could sell to the highest bidder but then that wouldn't be the "right" thing to do. I want to keep it becuase it is my "backup" turbo now, I traded my HY35 for credit towards my hood. And lastly it is the starter turbo in Piers twin system, so kepping it "just in case" type of scenario. Hope y'all understand... ... ... .

kat , why did you go with a 12 ? the big benifit i see with the 40 is reducing EGT , i imagine that running the 40 with the restrive 12 housing is negating any effct of lower EGT .



even though it is now cooler out the 16 housing on the HX40 keeps my egt gauge off 1500 , got what i was looking for , though quicker spool up would be nice .



anyone running a 14 housing ??? i need some real world numbers on a 14 housing to sway me in that direction ...



edited for spelling ...

 

[HEMI®Dart]

Will Kurt sell just a 'Kwik spool' exhaust housing for us guys that have a 40 already?

 

[Bob Wagner]

Bill

yes he will

I hate lag..... thats why I wanted to try the 12cm² housing first, Kirt left the option for me to switch to 14cm² anytime I wish.



Its lowered EGT's some, haven't trounced on it hard yet in Level 5.



Levels 1 to 3 are all usuable all floorboardable and highest it'll go is 1400°. I jsut wanted more topend and I got a lil bit of everything it seems, if the temps go up when it gets warm I m ay goto the 14cm² but until then gonna drive the hell out of my 12cm². With how well this turbo performs I am considering going up on injector size.



I still have room to play, highest boost I have seen is about 32lbs, going to get it adjusted to around 40psi and then check temps. I KNOW its gonna go faster this Sunday... . it has to. . I'm still smiling... ... ... ... .

 

[Briar Hopper]

I was told by Mark Chapple and several others that there's not much difference between the 12cm2 and 14cm2 as far as EGT's go. I was urged to go with the 12cm2. And they are all aware I prefer to keep my truck set up for towing heavy loads, not just drag racing.

As for Mopar-Muscle's question about EGT, the bigger volume and pressure of the fresh air side of the Hx40 is the biggest reason for lower EGT's. The concept of a less restrictive exhaust only works to a certain point. The faster the turbo spools up, the faster it can force air in to burn the excess fuel you're cramming in there. Without enough air, the extra fuel causes EGT's to skyrocket.

Look at the flange of the turbo, the inlet port that bolts to the exhaust manifold is the same size as the Hx35, and the Hy35. It all has to come out through there, and having a smaller exhaust housing on the turbo is still not going to appreciably restrict the exhaust as much as you might think... .

This is what I was told by several people who are widely respected in the diesel performance aftermarket.

Doesn't really matter why, as long as it works!

 

[Don M]

I got my Kwikspool installed today and can tell you guys I really love it.

I have the 12cm housing on mine. The turbo lag I had is gone.

This thing is awesome in second and third gears.

The EGT's are lower than my HX-35 with a 16 housing.



It is a screamer. I am getting roughly 42 pounds of boost right outta the box. Kurt said he had it adjusted to roughly 36. I guess I am dumping more fuel than others. The P7100 with the top secret fuel pate is making this truck blow smoke out I have never seen.



Don~



great product Kurt.

Ya done good by me!

I have had some discussions with fellow gearheads in the gasser world about turbo modifications. While they run at a max boost of 24-28 psi the theory is the same.



Ralph Friend the owner of excessive motorsports has an RX-7 that cranks out over 450 HP with one T04 turbo. He ditched the stock twins and gained a bunch on top end, but it was laggy below 3K..... the fix? a smaller exhaust housing and a computer controlled wastgate.



Where an I going with this?



Exhaust housing effectiveness is dictated by the nozel area where the gases are directed into the turbine. The best way to lower EGT is to cool off the intake charge! There is a common misconseption about this on TDR. The HX-40 lowers EGT mostly by the cooler air charge it produces.



I have heard that the HX-40 has a higher volumetric flow rate on the air side than the HX-35 at similar boost pressures... . this is not true..... the ISB can only take so much air... . 35 psi is 35 psi regardless which turbo it comes from... . the diference between the two turbos is the temperature of the air at 35 psi. Where the HX-35 can easily exceed 400F above 35 psi the HX40 is still at or below 300F at 35 psi. We all know that as air heats up it becomes less dense, therefore there are fewer O2 molecuels to support combustion. If we can cool off the air, density goes up, and Mass Flow Rate goes up, while Volumeteric Flow Rate stays the same.

Take a look at a turbo compressor pressure map... . the axes are pressure ratio, and mass flow rate. Volumeteric flow rate is completely arbitrary and should not even be considered.



The solution for quick spool up and EGT control... ... find a turbo with a compressor map that suits your needs and then adjust exhaust housing size and wastgate setpoints to make it rock( this usually takes some creative engineering and specialty machining). That is exactly what Kurt has done here. I am suprised no one has thought of this untill now.



We have seen a lot of developement with regards to fueling, now we need some more development with regards to air and EGT management. This seems a little backwards to me, but oh well.
