Thanks, TDR Staff

I could hit 75 psi on the street with edge drag comp turned off and 86 with it on--no NOS---on the dyno I think it was around 64 or so with no NOS and then 72 with NOS now that I think of it---no idea what the BB was doing..... chris

It depends on when the air is delivered. If it comes in too late for the peak fueling with a standard BB then a tighter housing on a BB would most likely net more hp (and drive a ton better) even if the drive pressure is higher.



Sound reasoning. I would think that it may come on a bit late.



If you used a larger compressor wheel on the secondary (bigger than a 40) you should have a denser air charge and thus more exhaust flow. Would it be enought to get move the BB's boost curve lower in the RPM range?



Ideally doing both would be great.

I ran a turbo with the same exhaust wheel and a larger compressor wheel (similar to a full B1) and it was slower spooling. The slightly denser air charge doesn't matter much in spool up times as you cant overcome the additional weight of the wheels.





Chris,



It sounds like you were making way too much boost with the top turbo.
 
very possibly and that's why I'm going to the divorced wastegate to balance things out--I may try to add another boost guage to see what's doing what--but with the Redline box and possible water addition I won't be able to see out the windshield with all the stuff on the dash-:D:D----chris
 
My . 02 is that Olee Poole builds one hell of a setup as far as twins go and nobody will ever be able to beat Don M's injectors. You want power, call the people who know how to make the real stuff.
 
Idaho, I have your old BB. . Just got the truck running a little while back. . I have the 66 on top. Poole built the twins. The total boost is only set at 65 pounds right now, though the BB is only making 20. Is that normal? It just doesn't seem right to me. I hadn't been able to play with the truck any until this past weekend, and I did find out it needs bigger injectors. Without the nitrous or water, it only smokes with a strong grey haze. Nothing like Darrens' truck, that's for sure. It has a set of Dynomite Diesel 4's now. I talked to them today, and they're gonna open them up some more. I hope this helps.

As far as twins, I only have experience with Poole. I was very upset that it took 6 months instead of the original worse case scenerio of three weeks to get my twins built. He's a nice guy though, and I have to say his work is top notch. The kit looks and fits absolutely perfect. The welds were again top notch. I could have gotten them quicker, though the end result was great.
 
I vote for you to call jr also. HE has so many different things he can do, but before you decide at least give him a call.

We are building twins, several different setups offered very good pricing. Also building a street triple charger setup. Check out our website www.woodruffdiesel.com for prices and pictures the phone # is on there if you have any questions. There is a picture of the twins on our site, and if you go to www.enterpriseengine.com and go to the vendors link you will see a picture of the three charger set up that is not up on our site yet.

How are you controlling boost? 20psi is low from the BB. I think Lenny's pump was only a 12mm right? You might be out of fuel.

What's the point of running parrallel HX35's? A HX35 flows about 550-600cfm which is slightly less than half of a B2 or 3B so it looks like a plumbing nightmare without any benefit.
 
I should have twins on my truck by spring break. This particular setup is tuneable from 59 psi to 137 psi. . without using pop off valves.



If I could get enough fuel to them to do it, it also "could" be possible to make 55 psi at 1100 RPM and NOT Surge!!! However this would never happen in reality. It's just an indication on how well matched the compressor wheels are.



It also has 16 different configurations depending on how much fuel and where you want the lower boost threshold... . Very tuneable!!!!! oh, and very expensive!!

I think sometimes people forget how important that is. It's not about size. It's about technology. Who read the write-up on page 130 of the new TDR mag? Most will read that and be in disbelief.

Funny thing, the term "technology" gets tossed around these days so much I wonder if people know what it means.



Take for instance a HT3B and a S400 at 65% efficiency they move practically the same ammount of air; 1230cfm, and 1236cfm respectively. If one were to go off this rating alone of what the turbo can do, they would be somewhat dissapointed.



It's not new technology, it the proper application of specific components.



People talk about compressors all the time. It's no big deal, and anyone can do the math to determine what compressors work in a staged centrifugal compressor.



The turbine side is the really fun part. There are very few turbos out there that when paired up have the correct compressor staging... . AND turbine staging.
 
Idaho, It's a 13mm pump. . More than enough fuel from that, though the Injectors may be a different story. DDP is going to open them up some more for me. . We'll see what happens.
