Kurt,



What level and sub-level were you running the Comp box?





Thanks,



Doug S.

 

[KWIKKURT]

Let's try it this way.

This was at 24,000 GCVW with DD#3's, a PE Comp and a B-1 Turbo.



If there is a + or - after the figure that means it is climbing or falling.



Most hill gradients and elevations are estimated



OAT = Outside air temp

IAT = Air temp at Turbo Inlet Elbow

CAT= Compressed Air Temp at Turbo outlet



On thing to note is I ran with the air cleaner laying on the Inner fender to simulate warmer outside temps because most of the testing I have done in the past with a HX35 and a KwikSpool Hx40 12cm2 was done in warmer outside temps. What I found from this is even with near freezing outside air temps that when I worked the truck on a hill the air entering the air cleaner was much hotter than I expected. Since turbos will heat the intake charge 300% to 500% this makes a BIG difference.



I will reconnect the air cleaner induction to outside air and retest. During the last week my CAT was never over 340 deg Almost 100 deg lower than during my testing of the Bombed Hx40.



During previous tests my IAT was usually about 6-10 deg warmer then OAT. Not 100 deg warmer. I expect this to lower EGT's at least 100 deg. Also during empty to lightly loaded testing the egt's never went over 1250 then would start to fall.



Question for you all. During this tests it seemed like when I would down shift to 5th for higher rpm's my egt's went up alittle not down like I expexted.



I hope to do another run tomorrow when the Oat will be about 65deg f, with the air cleaner ducted outside, with the same trailer & Passenger Data Recorder.

Doug S. The Comp levels are shown in the image above. As for sub levels I don't record them for the R&D test as they don't effect EGT's only the amount of smoke when you step down "Kwikly" on the throttle. Kurt

Hey Kurt.

Looks like the bombing is going well. Have you tried it on an automatic yet? If you would like me to test it for you, send it down and I'll gather some data for you



Good luck,

 

[Brandon]

rumor has it its a modded 4inch downpipe... .....





hmmmmm thats what the rumor mill says

 

[BPINE]

That all looks pretty good Kurt, I am assuming these tests were at wide open throttle? What's happens if you are crusing at 63 to 65 with the trailer and roll up to a 6% or so grade and just try to maintain that speed, what boost and egt do you end up with.

DevilDog,



We haven't tried it on a Slush-O-Matic yet! . With the latest housing I am testing it spools fast even at high elevations. So I am confident that it will work with the stock/Bombed Autos. I will check with Santa and see if you've been good enough for him to drop off a B-1... .



I think one of the B-1's shipping on monday is going on a auto.



BigCarl64 & Brandon,



The B-1 will bolt right up to most trucks Except for the outlet on the turbine housing. Their is a little confusion here as CUMMNSTRKN and I found out when we went to swap housings in Pahrump for his second Dyno Run. The HX40's have a 3. 5"Inside Diameter outlet and 4" Outside Diameter on the Vband Flange.



The B-1 exhaust outlet on the housing that 95% of us will want to run is 4" ID and around 4. 5"OD. I will have Down pipe elbows Made that will hook up easily to a 5",4" or 3. 5" Exhaust.



In the Attached Pic I welded a 4"x 45 deg elbow to the Flared Flanged Connection (Stainless Clamp,Stainless Flange & Aluminized Elbow $50) Then I welded that to my 4"- 5" Down Pipe.



There is a Adjustable Flanged Elbow that should work great. It will Clamp to the housing then clamp (If no Exhaust brake) or weld to the down pipe or there is a possibility that we can make a adapter that will clamp to the B-1 bomber and to the HX40 size down pipe. I will look into it soon.

 

[KWIKKURT]

BPINE, That's a good Question! "And Just Maintain Speed"I will have to slow down a little and try that out. I have found (unloaded at least) that I can change the PE Comp settings and the Cruise will work great. No hunting. I want to try it while towing.



I didn't get a chance to reinstall the "Scottyair" induction today and retest for IAT vs CAT vs EGT changes but will get to it tomorrow. Last night I finished after 2:00 am and I better not keep that up or I may be sleeping in my truck! (Again!)

Is the housing I am getting the one that uses 4" downpipe and V clamp? Or am I in the 5% class that it won't fit?



How many are shipping on Monday?

 

[KWIKKURT]

KAT, LOL I was wondering if I would be able to slip that one by you! And yes the one that you are getting for your 13. 4 sec Rocket will look like the one pictured. Two are shipping on monday. I will Email you details on yours tomorrrow. If you have time call me I have a question/Idea to run by you. You will be happy to know that the B-1 will fill that empty Void you get after not having the KS12 on your truck!



I will be in my shop tomorrow 505-534-0434

How late will you be there, I am heading to bed right now (since your two hours behind me I won't call yet )



I'll try to call when I get up this afternoon. Be looking forward to that email. So the one I am getting I can use a "typical" 4" downpipe and V clamp... right?

 

[HEMI®Dart]

In a nutshell, Kat or Kurt, how is the B-1 better then an HX-40 16cm2? ( other than busting).



Is it affordable?

 

[CUMINNTSTRKN]

kat



if your getting the one kurt has it isn't the normal hx-40 downpipe. the opening is bigger on the b-1.

Kat, The B-1 has a 4" ID outlet, and the Hx40 16cm2 has a 4"OD Outlet so they don't match up. But I do have several down pipe elbows that Clamp to the B-1 and then will connect to a 4" exhaust pipe.

Here ya go Blair. . All of these tests are with the cruise control on the same Hills/mountain grades as before.



The other BIG difference is I switched the Air filter from laying open on the Inner fender and put it into a "Scotty Air" Box. Look at the difference at the Compressor side Air temps and the Lower Egt's. The CAT ran over 100deg's lower.

 

[Forrest]

The #'s look good Kurt.



How about a competitive comparison between the B1 & a HX40-16. Can you re-run the last test case? In my case, like many others, I'm using the HX40-16, I tow a large 5'er & can now get to 1500 degrees.





Thanks

 

[KWIKKURT]

Forrest, 1st keep in mind that I have only tested the HX40's with the 14cm2 and 12cm2 housings. But judging by those the B-1 will spool up faster than the HX4016cm2, Run much lower EGT's, This turbo moves lots of Cool air. The best part about it is that this turbo is HeavyDuty... We are not going to be breaking shafts!!!



And for the High HP guys this turbo will run fine at 60 psi.

 

[Forrest]

Kurt,



Thanks.



The data will be interesting & will determine the $/benefit.

 

[Cummins Corvette]

Kurt, this is looking very good. If that wasn't the fastest spooling housing in your test, what is the fastest spooling exhaust housing going to do to those egt numbers? How much more lag is there going to be in comparison to my stock hx 35/12cm with the smallest housing on the B1?
