Ok heres the story:

I have been looking around because i need more power....LOL
This is what i am purchasing for my bombing:

Mach2's
ATS stage 5 with billet input and out puts and triple lok converter
FASS or RASP (not sure which one yet)
Pierce the wire on my Comp (after upgrading to the DRAG)

Now my question is if anyone has this setup and if so, which turbo and boost pressures worked best for you....I want my EGT's in check, and still want half decent spool up.

Thanks,
Jon.

 

A PDR HX40 would probably work. That or one of the b-1 series.

 

hummmm....Drag Comp, Mach 2's, fast spoolup AND EGT's in check, with a single turbo????

I think you ask the impossible.

KSB-1 is the closest you can come to getting everything on your list, IMHO, but you will still hit 1500+ degrees in a quarter mile. Full B-1 or one of the HX-55's will give you everything on your list...EXCEPT good spoolup, and my guess is you would not be happy.

Twins are the only answer for an automatic with a drag comp wanting hardly any EGT concerns. However, other than sustained WOT, you'll have a great set up with the KSB-1....or the PDR HX-40!

PDRHX40. Not as tough but a very durable turbo and it will out dyno a KSB1.

 

So just curious for all the guys that respond on threads like these... have you actually tested each setup you "advice" on or just relaying information you have read in previous threads? Nothing personal but your opinions would be more helpful if you just stated what you run and how it performs.

Most people stated that Mach2s, a Comp and a B1-2 at 5000'+ would be a smokey pig. That turned out to be complete BS. Spoolup is close to stock and smoke if easily controllable with right foot. All I'm saying is don't believe everything you read and keep in mind opinion is always subjective.

 

The downside to all this is everone's opinion on stuff like smokey, spool-up, and too hot are different.

What feels like stock spoolup to you could feel like an eternity to the next guy.

Hey Jon I'm running DD's comp,mach 3's & DTT's 89% trans and I upgraded to the b1-2 and I really like it.Spool-up is a little slower than my hx35 but easy to get used to.When the b1-2 starts to spool tho it'll hit 46 lbs in a heart beat.Egt's are also alot more managable with this turbo compared to the 35.Only regrets I have was not going to a bigger injector I was wanting to have 500 rwhp and I only have 485 rwhp.Mark

 

Duke - I totally agree...Important to add "I think" or "IMO" or "others have reported" if not first hand data!

Chris - While "smokey" is a subjective term, I feel spoolup speed and "too hot" are valid concepts for those who have switched turbos and have gauges. I get accused of exagerating every time I report my KSB1-2 with Mach 2's and an EZ, spooled as fast as my HY-35 did when stock. But with a daily driver...I trust my butt-o-meter.

Torqueman - Nice solid data

Pourin Diesel - Have you dynoed a KSB1 against a PDRHX-40...on the same truck? Please clarify your source. I trust Wildcat Rod's data that a KSB-1 moves 900-950 CFM. The HX-40 has long been published to put out 800 CFM. I would expect this difference to show up in the B-1's favor on a Dyno, with moderate to heavy fueling. If not true...many of us would love to know..

Ok, I'll buy that

I gotta get my hands on one of these B-1's so I can be in the "loop." I'm still hot roddin' this 35 to death

I am looking at those cheap BD twins, though. Not very hard, though

 

A full B-1 and a PDR HX-40 both make virtually equal HP. The difference is in the spoolup and durability, the PDR 40 spools slightly faster but the B-1 is much more durable for guys running NO2 or pulling. I have seen the smaller housing B turbos make less HP than an HX-40 on the same truck due to backpressure......

No true flow #'s exist for the B series turbo as they are hybrids that "in theory should flow" a given amount but no such testing has taken place to my knowledge.

I guess what I am saying is that full B-1, B-1-2, or KSB-1 turbos are great and durable but as far as HP is concerned they don't produce any more the a good HX-40.

I run the bd twins in my 01. BD took there Silver Bullet dodge ram up to 760 rwhp and ran a 12 second 1/4 mile with the twins

 

Hey tourque man.....you say that mach 3's and the b1-2 gave you 485?? Well i think i might have too go that route then!! I was just thinking about 400 but if almost 500 is that close why not go for it right?? Ah hell i might have too go with a twin set-up and try for over 500....

 

Hey Jon if your gonna go with 3's I'd make it the mach 4's their the same price and a few more ponies.Especially if your thinking twins.I'd sure like to switch up to 4's if I didn't take a beating on it.I wander what the vendors would soak me,my 3's are only a few months old.Ya I guess twins would be nice but the pricing a little high so I went the b1-2 route with no regrets.I don't tow and altitude isn't a issue,I'd sooner spend the coin on other parts for now. Thanks Mark.......

 

I would give J.R adkins a call. He has built some pretty tuff turbos and can make something to work for you.
If you need his Phone number shoot me a PM.

Mark, what egt's do you see?? here in edmonton i am only about 1500' higher than you in winterpeg.....i know what ya mean about the twins....not only the turbos and piping, but the head work is the real kicker..... thats why i was thinking about the single turbo and get it upto the 450 area. What kinda fuel mileage are ya seeing at with that setup?
