Anyone really pushing over 500 RWHP?

[geusterman]

In defense of Piers... (not that I really need to)... he is just beginning to work up his 600 and does R & D as he goes particular to the market he serves... which is towboys first and monster boys second (IMO). George

I am with mattymac and Big MAK,I want the big numbers and still tow without dropping the box to have a livable egt. with twins it appears to be the best way to get big hp and trq and still tow with it. I agree it is very expensive to do it. I know of no single that will tow with 500+ hp. maybe the dd turbo does,I have not seen one yet. kieth are the dd turbos doing 500 hp towable?or will egts be an issue on long grades pulling 10,000+.

The kit we sell for the 3G trucks will support about 400rwhp for towing. That means up to Stage 2's with the box turned off (which is why our version of the EZ has a "0" power setting). Stage 3's will get hot and you will have to back out with the power from the box off, as will you have to with the box turned on with 2's or 3's. With a manual, this isn't that much of a problem. With an auto, it's the quick way to kill the trans.

"I will state quite emphatically the ATS manifold lowers EGTs"



Hey Big MAC, how much would you say the ATS manifold lowers EGT's???

Hey Kieth, I know you dont test the TST, but what would you say would happen with lets say your 80 hp injectors and the TST on 1/1, (timing only)? I think that would be better for EGT's while towing and then just run it up to say 4/4 5/5 for playing around empty (with a good charger of course) Then I would think that would be a good combo because I have proven (to myself atleast) that the TST isnt to destructive on 5/5 and lower. So with my will power of not going over 5/5 and good injectors I think this should be close to 500 HP (with the other supporting hard parts) with slightly better EGT control through timing. Also I have heard that the TST and any charger would work better with a good external w/g to get rid of some of the destructive backpressure? Can we have your expert thoughts and opinins? Thanks Kieth.

 

[KLockliear]

Never tested that mattymac, but we do not suggest running our turbo with the TST box at all.

 

[mattymac]

Even on the lower settings? I know you cant gaurantee that myself or the next person in line to get your or someonelses turbo and run it with the TST on any level wether it be 5/5 and lower or 9/9 all day long. You dont want your product to get trashed by someone else being stupid and not respecting what their truck and supporting equipment can or cant do I understand and dont blame you. I also know that you dont R&D for the TST box but I was still curious if you have heard or just known of a few cases of people running the TST injector combo and what results have become? Im sure they are out there and you have a better chance of hearing about it than we do, thats the route Im going to go at this point, TST, 80hp inj, and whatever turbo is working the best then just see how hot everything gets. Thanks kieth.



Hey one other thing, this might be kinda crude but do you think that you could put a second map sensor in the intake to be used as a true readout for a stacked pressure box, or would it matter because the boost fooling doesent occur until higher in the boost scale? Just a thought.

 

[FDavid]

Hey Keith, why don't you reccomend big injectors with a EZ on high levels? Is it Because of EGT's or something else?

I know BCarmichael truck made 570hp on #2 with twins. I don't think he has tried nitrous yet.



qzilla how are your D-Max LLY boxes for huge power coming, I need to stack for big @#$ power. Trans is done, now we need the power. :{



Got DD Module with monitor, and it's a whole new truck, power is awesome, so I figure if I stack-it maybe I'll have another all new truck.

 

[Piers]

I would like to point out one thing about the 460hp run, it was done on a load dyno and at 58lbs of boost, the pyro hit 1230 degrees. On the street, a flat out run will net me 64lbs boost and 1335 pyro before I hit the rev limiter in o/d... can you say the same thing about your single charger numbers?



Hey Stefan, when ya going to change your sig... . I mean you wrote off the 2000 several months ago, time to tell us what you are driving now.

 

[KLockliear]

I can't speak for all the boxes, but I believe they are all in by the limit of the stock boost levels, meaning that if they are stacked, they will still do their thing.



On the TST/Injectors thing, yes, I'm sure it would live if the DRIVER drove it knowing what the combo could do. I mean, look, there are guys out there making 400+hp with a HY turbo... not what you should have, but it can be done. And you are right, we don't want our turbo to get a bad name or get blamed for blowing up when it's the fault of a too aggressive box.



The other thing is you really have to want to go mental to use that combo really. 500rwhp is obtainable with just a pressure box, injectors and the turbo. It's way smoother, more turbo friendly, and has been out and available longer than anything else. If you're looking for more power than that, then the bigger boxes are in order, but so is a bigger turbo. We do have one being built for that scenario.



FDavid, EGT is the limiting factor. You can drive around town and tow light all you want with the EZ on 4 and Stage 2's/3's with the turbo kit, but if you go to tow heavy, you'll be modulating throttle or turning the box down/off to keep the EGT's in check. With the auto, because it's internal pressures are all based off TV cable input, you're best off to turn the box off and use more throttle input. Doesn't matter so much on a manual.



Come on now Piers, you couldn't load it up enough on a load dyno to get the boost?

 

[BRayls]

"We do have one being built for that scenario. " the reason I am waiting till spring to do the turbo swap. hoping the new one will do 500HP and tow.

 

[mattymac]

there are guys out there making 400+hp with a HY turbo... not what you should have, but it can be done.

On 5/5 on the TST I made 377hp and 8/6 I made 450. 1. I dont run it higher that 5/5 on the street because of the EGT's and the clutch. That little HY can make 400+ but it cant support it.
