Who makes the latest greatest twins and injectors?

[driverno8]

Just contacted Mark Kendrick today about twins. Wifey game me the goahead. So Marks going to build them. HTB2 /B2 combo. I already have the HTB2. Can't wait anylonger for HTT.

 

[AFarmer]

I would love to put a HT62 on top of my twin setup. I think you'll have a horsepower making setup when you put a B2 on the bottom of that thing. Olee has already made a set like that and he actually has that kit alread built and ready to ship. My next buy will be a larger top turbo.

Are you going to tell us what your Very expensive set-up is?

possibly... depends if it works or not. If it works I will tell you all about it, after you pay for the intellectual property!! :-laf



That will be real cheap ($1200) compared to the turbos!!



However, it is quite possible that I re-invented the wheel. BD's wheel that is. My useable HP goal was a little higher than theirs.

 

[BTighe]

id save all the bragging till you have something that proves itself. might look like an @$$ later. will it really be worth the extra money. some how i doubt it. cost has to play some part in it. unless your making the next power pack.

 

[Hohn]

and nobody will ever be able to beat Don M's injectors.

OK, it's one thing to be a big fan of someone's products. I happen to have have Don's 4s and i *love* them.

But the above statement is just foolish. Technology moves on-- at ever faster rates.

Don M is the type the will fight and fight to stay on top. But that doesn't mean he will.

No one will EVER make a computer faster than a 386, right? Oh wait...


Don't let the admiration you and I share for Don's injectors cause you to make generalizations that deligitimize your opinions.

Where are the compressor maps? Or are you under a NDA? :-laf

that is entirely possible, there is only one way to find out!!!



The is not a mass marketing project. If I was going to build a setup to sell, there are many parts that would not go into the final product. I am well aware that 40/3B, 40/S400, 35/3B, 35/S400, S300/S400 etc. etc. setups work, I just want one that works better, and is "properly" adjustable and tuneable. The previously mentioned systems do not allow me the lattitude I want.

The compressor maps are in my junk drive. No NDA's here!!!!!



I just dont feel like sharing at the moment. However, the maps are readily available to anyone willing to look for them.

 

[Diesel Freak]

Just one more thing. If you want to know who has the best turbo setup, when talking to the vendor about it, ask them what the estimated density ratio is for their system. Then ask the what the boost pressure is to get there.



If they can not tell you, walk away.

 

[LEggers]

I think I would have to go back to school just so that I could ask them questions and know exackley WTF I was going to say if the guy gave me the answers.

 

[Diesel Freak]

heh heh good point!!!

I already talked Poole about it. He's not ready yet to ship. I've called a few times and it's 2 weeks... 2 more weeks... . 2 more weeks. I don't want to wait any longer. He was my first choice on this project. But I've heard stories where it takes 3 months or longer to get them. There's no doubt he can do them and do them right, I just don't want to wait that long.

DF--if any of the builders could answer that question I'd be totally surprised---'ell no one knows to ask those types of questions unless you're totally turbo literate and the general masses aren't---bottom line is do they do what you want them to do---the tuneable thing is an interesting concept though, but how world friendly will it be--can you do it from the cab or must you tear a turbo apart and change a housing or ????---sounds like fun no doubt and am anxious to see how it turns out--chris

 

[RBratby]

did anybody notice in the pictures of j. r. adkins turbo setup the cold pipe has a v-band clamp and not a boot? look at the picture of the top turbo.

That just it. I know alot of people have done their home work and know way more than me about twins and injectors. I'm relying on honest answers from the educated few on this subject. And of course I'm learning as we go, What I've learned so far is that there seems to be no easy way..... or magic combination or is there... ...

Thanks.

IMO, there is no real magic combo. Pick a continuous power level, and tune for it. Peak power numbers on your local dyno are great, but it sucks when your 474 HP truck running down the freeway grossing 19K can not get out of it's own way without thermo-nuclear EGT!!! Been there, done that... got the "t" shirt!!!



Not all setups work for every application. Some work for a range of power levels, but they can work better. Take for instance Boost control. Letting the primary do what ever it feels like and then regulating pressure with the top wastgate... and then dumping the excess with pop off valves wastes more power than people realize.





Chris, the tunability has to do with the wastgating and available exhaust housings for the primary and secondary. I am anxious to see how it runs also.

 

[BTighe]

why dont you let byron test em

 

[Hohn]

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.

NO joke. Not to mention that each of the parallel '35s is only getting half the drive energy, so they would be laggy-- equivalent to an HX35 on an engine that's half the size (~3. 0L). Then you FURTHER increase the lag by making these turbos both inhale and exhale through another, larger turbo?


While I respect the fab skills required to pull it off, you gotta wonder about the understanding of turbocharging


If you're going to mess with Triples, stage ALL THREE of them. Something along the lines of HY35/9----> SPS66----> HX60

Or if you're going big:
SPS66---> HX60---> HX82


My personal rule of thumb: the small charger should flow about 2/3 of what the big charger will do (in lbm). Or, stated another way-- the big charger should be 50% bigger (in terms of lbm flow) than the small one.

I've never built twins, so feel free to diss my opinion as illegitimate

 

[AFarmer]

Just to set the record straight, the ht62/b2 is sitting in his shop and ready to go. If you'll look on ebay, you'll see what I'm saying. Good no GREAT things come to those who wait. Be patient. Oh yeah, twins are on ebay for $4200.

That's Exactly what I don't won't is a laggy truck, I 'm trying to get great street performance with high HP and to be able to tow a 5000 pound boat from time to time.
