B1 turbo on 6 speed

[rubberneck]

Ok, I picked up my B1 turbo from Nowel (HVAC) of performance diesel last sunday. I have been waiting to post my results to date, as i wanted to get some miles on it and give a fair, real world evalutation. I know max boost and egt numbers are important to us, why else would we be changing turbos in the first place. However, for me and im sure most guys out there, who can't afford to have a toy and a work vehicle, there is the daily driveablility that we must maintain.



Ok before with my hx35, doing 1/4 mile runs with G-TECH pro, i would be hitting high 1500s to mid 1600's consistantly at the end of each run @95 mph. Boost was 45 psi with the Powermax Comp set to nuclear melt down. Now with the B1, hitting 50 psi, the hottest i was able to get it the other night on 4 back to back runs was a spike of 1408 on the SPA memory. The funny thing is the egt's would spike in the mid 1300's and then actually start coming down. On my last run, the one where i spiked 1408, at 100 mph the temps were only 1323. I am getting a legitimate 250-300 degree reduction in temps over the hx35. As a matter of fact, with the pm comp off, running on only the dd3's and the EZ, i have not been able to get it to 1100 degrees yet. I am hitting 40 psi with just the dd3's and ez.



The boost and temps just do not tell the story with this thing. The drieveability and response is incredible. It really spools almost as fast as my hx35. From 10 to 30 psi goes by in a flash. It is unbelievable that it spools so quickly yet still flows on the top end. I can not wait to tow my trailer with this thing. As quickly as it responds, i am expecting nothing but smiles.



I had hoped to compare #'s with MarkKendrick because we have very similar set ups now. But he so inconsiderately turned his OEM clutch in to a torque convertor before he could lay down any real #'s I know he dynoed his truck on a real dyno, so i was curious about what i am laying down. However, Using the dyno feature of the g-tech, i would get cosistant mid 390's with the hx35. Now i am getting 430's with the B1. 40 hp Oo. that rocks. It really wakes up the top end on my truck. Again i would like to give a big thanks to Brandon for his help with the install and fitting of the down pipe, and to HVAC for supplying the new hair dryer. Hey kwikkurt, i would just like to thank you for selling your soul to you know who, cause that's the only way i can imagine this thing is woriking as well as it is.

Awesome!!!

That's a terrific real world report complete with specific comparison results. Obviousely I'm extremely happy to see your enjoying the magic B1 Turbo.



If anybody was waiting to see if the B1 was only smoke and mirrors, let the score show overwhelming and repeated success for the B1. This thing just kills egts.



If anyone has any questions about the install or otherwise, please take the opportunity to let everyone read your comments.



Hey Rubberneck, you better start wearing a helmut and one of those NASCAR harnesses!

What do you mean start, i already am. Oh yeah, i'm going to put some ground effects and a big spoiler on it too. I want a lead role in The Fast and Furious part 2

Rubberneck, thanks for the great report.



There are a couple things I want to know, regarding daily around-town drivability:



1) How fast does it spool from and standing start using only DD3s (no boxes on) compared to your HX35? You commented it spools nearly as fast but was that with or without your boxes?



2) If you do a quick start without your boxes on how much smoke do you lay down compared to your HX35? And when you pull away from a light can you take off as fast as you could with the stock unit without making any smoke?



3) What have the outside temperatures been like in your area lately?



I ask this because when it gets into the 100s here (often in July/Aug) I lay down a lot of smoke with just the DD2s unless I go nice & easy. I have to lean into the throttle very gradually and let boost get up a ways before I can lay on it. Off boost I would suspect the B1 would yield more smoke in very hot weather but once boost builds it would be a great turbo to help keep intake heat down.

Rubberneck---cool(pun intended) turbo-- data---that's what I've noticed on the temp front--she peaks & then she comes down---problem is it's hard to watch the ol' guages and road at the same time---



Vaughn--I think there will be less smoke as this baby spools--I'm sure Rubberneck will let you know for sure----chris

 

[rubberneck]

Vaughn, spool up without the boxes is "very slightly" slower. This was one thing i was worried about, as I know what you mean about hot temps and and smoke. When it gets in the 90's and 100's i to have to be aware of the smoke pedal. Right now it has been in the 50s and 60s, so smoke really isn't an issue. I would tell you that when i jump on it hard with no boost, i get a little bit more, but not much, it really does spool fast. I can't stress enough how much this thing shines from 8-10 psi on up. Boost does not build, it rockets up. I would tell anyone out there that injectors alone spool this thing very nicely and would make you very happy. To be honest with you i had been driving around with the pmax on level 2 all the time. since the turbo, i have been leaving it off. The felt power is that much of an increase. The truck just runs so much differently now, its like learning to drive a whole new truck. I actually have had to work on shifting faster as i kept over-revving in 2nd and 3rd when hotrodding. I just cant tell everyone how happy i am right now with the way it is running.



It finally runs the way it should have from Dodge I have been thinking about developing a drug habit. (need to test how good that head gasket is) LOL.

 

[rubberneck]

Forgot to add, chris is correct about 1 thing, once spooled, there is no smoke. With the Pmax set on kill before, i used to smoke at 45 psi with the hx35, now it doesn't even so much put out a haze at anything over about 20 psi. Like chris said, kind of hard to watch the gauges, the road and the right side mirror to look for smoke, but bottom line it kicks major behind.

How much and where did you get your B1 from?

 

[Cummins Corvette]

Are you at sea level? High altitude sucks.

 

[rubberneck]

Blair, i got my B1 from HVAC at performance diesel, call him, he will get you a price.

canderson, i am at sea level. Yes i agree high altitude stinks, this thing acts so much like my hx35 on the bottom, i dont think it will be anymore of an issue than it was before. It is way better on the mid and top, so under boost I imagine it will be better at all altitudes compared to the hx35



Something i forgot to add to my previous posts. My induction system is a k&n re0880 with prefilter sitting on the fender well. I know for the absolute lowest possible temps that outside air is best, however i wanted an apples to apples comparison to the hx35, and that is how i had it before. I just hate the sucking sound of the psychotty, so i will keep looking.

 

[Vaughn MacKenzie]

rubberneck, thanks for the info . Having less smoke say above 20psi makes sense, less heat going into the intake = less smoke.

[rubberneck]

Vaughn, if you get a chance to ride in/ drive a truck with one of these things, i think you will be happy, i just can not say enough about it. Kwikkurt did his homework.

 

[drawson]

rubberneck, Try this for us and tell us what happens. Get it in direct (5th) with the RPMs down around 1200 and throttle slowly and tell us where the boost starts at.



Thanks

B1 Turbo Performance

Dee, how does your turbo perform under those parameters? Maybe we can make a comparison. I have seen a lot of data posted from those running the B1, but nothing from those of you that are running other turbos (OK this could be my fault). Tell us how your turbo affected egts. Did you notice a difference in boost pressure? I know I'd like to know how the other turbos compare. If you posted info like this then email me a link or post one here so I can do the research.



BTW, I'm going to get one of the B1's back to the formidible Edge compound for analysis. I think one of the most intriquing points of the B1 is it's magic ability to kick the snot outta egts. We'll be able to turn our comps up to the "Frappe" position once we take our egt's out at the knees.

Maybe you will have time to drop by.

 

[Mark_Kendrick]

Well I fixed my torque converter, i mean clutch problem:-laf



I found a way no to over rev in second. . launch in third. I found that I rev so fast in second that I can't build boost till I get into third of fourth anyway.



My clutch has not seated yet so is stll slipping a little at 440HP!!!(less than 200 rpm surge)



Spool up is incredible. It runs great w/the PEC off. I leave it on 1/1 most of the time to control the smoke a little. The boost does rochet up like rubberneck said. the only problem is that I run out of revs. The dam thing revs so fast that you have a hard time shifting. . hence the 3rd takeoff. I found that by skipping the no load time and the extra shift all is better and boost has time to build before 4th.



My real problem is trying to hit top HP. I can only do it well in 6th and by the time boost is hitting 44psi for any time I'm running 100+ and hunting for flashing lights





I have not seen the top side of 1300* EGTs since the new turbo. IT IS THE SH!^!!! if you want a runner that will tow and be well mannered enough that the wife or a relative can drive it then this IS THE ONLY WAY TO GO!!!



I'm still amazed every time I floor it. :--) :--) :--) :--)

 

[Floor It]

STOP! you guys are driving me crazy! I'm waiting for mine and can hardly waitOo. Oo.

 

[drawson]

Here is the data... Running in 4th(direct) at 1200 RPMs and I throttle it boost starts at 1400 and builds fast!!! With my old HX35/16 I got boost at at 1350, so with the Piers HX-40/16 I lost 50 RPMs to lag.



My waste gate it set to open at 38 psi and under a hard pull it will stay at 40 psi in 4th and 5th. I can get 36 psi in 2nd and 3rd and the RPMs zing to 4200 RPMs in 2nd if I'm not careful



As best as I can tell I have lost 150 deg in EGT with this turbo. Even in the cold weather up here I can max my gauge out still1600 + But it takes longer to get to this point than before.



I am trying to find a band clamp that I can take the elbow off my old HX35 and get my new turbo HTC coated and while doing this I was going to get some good data.

 

[rubberneck]

drawson, i think i misunderstood your question earlier, but here is what i did this evening. I took your question to be rolling in direct at 1200 rpm, accelerating lightly as not to make smoke how quickly does boost climb. So here it is. Again, i was lightly easing in to the throttle as not to smoke. RPM @1200 -1250 (engine on the center notch of the tach between 1000 and 1500) start to accelerate, by next mark on tach i have 5 psi, by 1500, 10 psi. this is with no smoke. With boxes cranked on and no regard to smoke, i can imagine it would be much better. I will tell you this, when really getting on it, once this thing hits about 12 psi, it jumps straight to the moon, i mean watching the digital gauge, i swear it jumps straight to like 25 and then onward. I really am very pleased with the manners of this thing.



(edit) I dont think i mentioned it before, but This was with the pmax off, I am running the dd'3s and the EZ on the most aggressive jumper setting outside temps were 62 degrees. oh yeah, just for kicks i put it in 6th gear at 1000 rpm and throttled it a little, 2 psi by 1200 rpm

 

[rubberneck]

Hey mark, what is your technique for launching in 3rd gear? How high are your revving it before dumping the clutch? or are you feathering it a little off of the line?. . I have the 3. 54 rear end what about you? I have given this great thought, but have been too scared to try it up to this point, but i think it would make a huge difference in my et's. My speed is good, but my et's kind of stink.

 

[Cummins Corvette]

Good job rubberneck! That is some good useable data. Thanks! Oo.
