Kwikkurt's B1 On A 2001 AT

[HVAC]

I'm real happy to report that the B1 turbo is the best single turbo I have had the opportunity to test. This is a

phenomenal component for your diesel truck and a dramatic leap forward expecially for those hampered with

the HY35 on their late model AT truck.



We have the B1 with it's smaller turbine housing in order to work nicely with the AT on our customers "01. Well,

it amazing to me how well this turbo works. It blipped the boost gauge to 40 psi without effort. Beautiful

drivability!



So what's the bottom line?



NOW HERE THIS!!!



In addition to the driveablility, we repeatedly watched the gauges attain 48 psi of boost pressure while

remarkably the egt numbers ceilinged out at 1250*. This is baby food as far as egt goes.

THESE FIGURES REPRESENT A 10 psi IMPROVEMENT IN BOOST PRESSURE WITH A DECREASE IN EGT OF OVER

400*!!!!

B1

Could you give the specs on the truck tested?

 

[KatDiesel]

Lag report?



I'm still waiting for mine... ... .....



Also how much fuel was on that truck?

 

[rubberneck]

Yeah HVAC we wana know man what did that truck have in it.

 

[BigCarl64]

I am definitely interested. What type of trans setup is in the truck and how much fueling does it have?

Come on Nowel, throw us a bone!



Rubberneck, you get that Mallory installed yet?

 

[JR2]

Nowel - more info please..... How much fule is this "customer" running??

 

[24V-DSL]

Need more info....

What size is the "smaller turbine housing" ??



Like Kat says... . lag report.



TIA

OK, so the truck was a 2001, AT, 4x4. It has Diesel Dynamics Stage III injectors, a Edge Comp, a 4" exhaust, and the Performance Diesel fuel sypply system. The transmission has been gone through to hold the power as this truck is intended to be a hot rod, no towing for this ride



Turbo Lag??? Please reread my first post.



Kurt asked me to disable the wastegate since he predicted we would not have a drive pressure problem. We have not checked drive pressure yet but locking the wastegate down makes for a very responsive turbo as you can guess. Lag is not an issue.

 

[Diesel Freak]

more specificly....

with the Comp on 1/5 what RPM does the turbo spool up at? I am asking this specific question because I need a bigger turbo, and I also want 20 psi minimum at 1600 RPM. Is this possible with said truck with the Comp on 1/5

Specific Testing

DF, the truck is currently enroute to nowhere imparticular, somewhere in the motherlode area of the Sierras. We can only hope that the owner turned test pilot will have the breath to share his impressions with us on Monday

More Test Data

Well Freak, I happened to get a call from the happy owner of the B1 today. I asked him if he would check his boost level at 1600 rpm. He just sent me this email-

-------------------------------------------------

I ran the test quite a few times with the comp box on level 1/5

overdrive turned off: going approx. 1200rpm in third gear I give it as much

gas as I can without it gearing down, the boost level will be approximately

18 or 19 when I reach 1600rpm.

With overdrive on: going approx. 1200 rpm in high overdrive I drive the

same way enough to accelerate but not enough to make the transmission gear

down the boost level gets all the way up to 23!



Note: I also tried this many times with the fueling box turned off and

experienced the following.

Overdrive off-- 14 to 16 lbs of boost

Overdrive on--- 20 lbs of boost



Hope this is helpful. David D.

-------------------------------------------------

Now, give us a harder test. Like how much boost we can make in reverse or something!

 

[Diesel Freak]

That helps a bunch. I was concerned about lag and how much fuel is neccessary to spin that thing at lower RPM. Drivability and power are what I was after, and this looks like a turbo I may want to check out... ..... the KwikSpool HX40/12 sounded good, bit they died like all the other HX-40's.



Does the B-1 spool up faster than a HX-40/16? with the same fueling?

B1-> A Versatile Weapon

I've talked w/KwikKurt at length about his turbo and ...

Smaller and larger is relative to the other housings used for this turbo. .



The turbo is made from a conglomerate of parts so even if the drive housing were a 12cm, the size of the drive turbine in the housing would negate the relevance of the drive volume measurement. A 12cm housing designed to have a large wheel in it is larger than one designed to have a small wheel in it.



I have been told by Kirt that the turbo spins up great on a 325-350 hp truck and will supply all the wind for 550+hp with lower egts than an hx-40, to quote him... "If you had told me that a turbo would do all this turbo will, I would had called you a @#$%^&* liar and an idiot, but I've seen it and its AMAZING!!"



I have an order in for mine. . I'll be installing Injectors, EZ Comp, exhaust and a B1 all at once i can't wait!!!

 

[Cummins Corvette]

FINALLY, A LAG REPORT THAT I CAN USE!! This is encouraging. Kurt you can expect my order as soon as I have enough money. (That may be a long ways off with how much you want for that thing. ) I have been bouncing back and forth between the B1 and Piers' hx40 for a while. If the lag is tolerable, I will get the B1.

 

[Mark_Kendrick]

I was takling to Kurt about the 'Huffed' hx-40's and he and the man that assembles the turbo's says they're all but bullet proof.



While testing Kurt had FOB damage that would have destroyed the hx-40. . they cleaned it up, rebalanced and reinstalled. the object that went through the turbo went in the intake banged up a piston and valve and went out the back side, WOW!



Plus the shaft is way bigger so the joint to the ehaust wheel is a lot larger. The ex joint is where the hx-40's were failing.



I'm salivating just thinking about it!!!



here pavlov.....

<b>That is one BOLD Claim</b> Does it come in writing?



Bill K. has one hell of a transmission but even Bill claims it aint bullet proof.

 

[HVAC]

Potentially Confusing?

Bob, that statement you quoted is misleading IMO.



The guy(turboshop) doing the assembly is doing the work on both the Kwikspool turbos which are on a HX40 chassis as well as the B1 which is on a [CENSORED] and much larger chassis. If I might rephrase his statement, the B1, due to it's significantly stouter platform is virtually bulletproof when compared to the longetivity of the HX40 in whatever guise one might find it.



Like any turbo with a larger center section, the B1 will be more stable. Similiarily, a trans with larger output, input shafts should hold up to greater abuse. We plan to do just such an upgrade to my trans to improve it's structural integrity. No more MR. NICEGUY!!!

 

[yogibear]

Bob, Kurt said "all BUT bullet proof". There ain't much you can't tear up if you try real hard. You have to see the B-1 beside the HX-40. As soon as I get the pics. back to Kurt , he will post them. Its impressive as he!! to just see it!! I thought the KwikSpool was impressive compared to the HX-35 I had, but the B-1 is another BIG step forward. That wheel and shaft is large. I just got home from Kurts. The BHAF is not working well. He put my "Brandon" modified stock air box with Amsoil filter back on, and it is working much better, about 150* to 200* less egt'sthan the BHAF. I've just tried it running empty, won't be loaded till Wed. or Thur. Will let Kurt know then.

Yogibear, Are you going to make the dyno day in K. C. on the 27th? I would love to meet you and see the turbo that might be in my future.

 

[yogibear]

I sure would like to. I wanted to dyno it with the KwikSpool to see how much more it was, but didn't get to. At MM it dyno'd 360. If I'm not on the rd. , I'll be there.
