Excellent info Mike, thanks for posting it.

 

I am using the TN BB unit on my truck. I towed in my 60 tow tune over 2000miles recently.

I am very pleased with the turbo as a whole. It is louder than the stocker but I also figure that if I was running a non-6673 intake it would quiet down some. I do not feel it is unbearable at all. And being into performance items I like it.

It spools well and shows no signs of surging.

 

Are you running injectors with this turbo.

 

Stock injectors.


It will smoke in the 80 econ tune

 

I am *raises hand* However, this even does a good job at cleaning up a set of stage two's. Not stock-clean, but it doesnt leave much more then two little hazes, and two black marks.

 

I have seen two Excursions and 2 Superdutys with the H2E setup.

One has stock injectors, stock fuel, stock intercooler, and the H2E turbo. Runs very well. 2003

the second Ex has stage I (160cc), BTS Big Oil, airdog, DI intercooler (DIIC), with the Stock H2E, also a sweet setup. 2002


The other truck is a 99.5 F-350 Dually. Running the stock H2E, stage III injectors, Rockin S fuel, 6.0 intercooler - puship 500 hp+

another 99 (Luke CLine) is running the Modified H2E with his 600+ hp setup and loves how the turbo works for him.

I have also seen 1 with the Garrett GTP38R, stock inj, stock intercooler, AFE stage II intake. Ran very well also, 320 on the dyno.

To me it looks like the H2E is a good turbo for multiple ranges of power & setups, and according to the maps Mike posted it does better at the higher HP levels. Jerid is going for a setup around 400 hP so he can't go wrong with either of the 3 turbos mentioned (the 4th not mentioned is the Van Turbo -which is also capable of 400 hp at 1/2 the price). I guess it would come down to price and if they were all in the same ballpark I would get the H2E.

 

OK, I kinda posted the maps with no comments of any worth. Now here is my opinion. The H2E rocks, period. But it is a pita to install with it's different mount and may leak at first. Not personal experience, but what I have heard and read. It can make huge #s though and is not bad laggy down low from the folks I have talked to.

The TN seems to be a good turbo. Now just look at the #s posted on the other maps and interpolate them onto the Ballbuster. Doesn't look good to me. All the HP #s I plotted on the H2E and the GTP38R would fall way on the right/up on the TN unit I have a map for. Perhaps the new TN BB unit uses a different housing or wheel but I doubt it.

Sorry CSIPSD. The #s are staring at you in the face. Whatever you have experienced may well have been an anamoly. You cannot change a turbo map because it makes you feel good. It can flow this much, and it is done, then checks out, period. I bet I could make way over 40#s of boost if I removed my 1.15 non WG housing and put the 1.0 unit on. So now I am boosting and it is so inefficient I am not really boosting. I happen to like my 1 to 1 drive ratio at about 32PSI.

I wish I had a map for the van turbo. I do know it is a capable system, I just don't know how hard it is working after about 350HP.

Just thought I would add that for shoppers.

 

Ok. sorry didint understand what you said about the TN. about numbers falling hight right??

 

Im just kinda scared that the garrett will surge from what I've read.

 

Then buy the Turbonetics

 

U cant get the Garrett at this time anyway. They are redesigning it and it sounds like to cure the surge issue. Also, if u decide against either the TN BB or the Garrett BB, there is a newer turbo out by PDR, which is supposed to spool very close to a BB turbo. and it runs $1300, which isnt bad. I hear it screams just as well and performs pretty dang close to the BB turbos like i said.

 

What was being compared in the graphs is how the TN & Garrett turbos move out of their efficiency range (from center to top right on the plotted hp levels) at levels over 400 hp.


Kris, don't forget to post you dyno results from today!

 

If you don't tow, then i guess i would have to say, get the garrett. I was talking to Boggerr today, and he said as far as power, the Garrett was much stronger and cleaned up the B codes *a little* more then his BB 1.0 turbonetics. He said if you tow, the TN is better because it won't surge, however he said he could get the garrett to surge a little.

 

I C. Well im still in the process of buying injectors and tuner. I got slowed down this week by another mod. Its called the truck payment. lol But I think I like the garrett now?

 

I do not want to be misunderstood here. There is nothing wrong with the TN BB unit. The map I posted is for a TN Ballbuster unit which I believe is similar characteristics as the BB unit as in wheel and housing dimensions. If not, the map will be somewhat different.

I made the comment about the TN unit for CSIPSD because I know he has had some bad experiences with the Garrett and generally does not have much good to say about it. He, along with many others like the TN a lot. I say both are good turbos.

The other reason for posting the maps was so you could see where the dropins begin to sign off. The H2E has much more room to go.

Good luck with your choice. I don't think you can go wrong unless you want to make some big HP #s. At that point you need to consider very carefully. A van turbo can make 400+ but I have no idea how hard it will be working there.
