Anybody ever tried a b1-2-ex3? They are very quick as well.

 

Duke, I'd go with a B1b if you have manual tranny, and KSb1 if you have auto.

BPONCI-- The B1-2ex3 is the same is the b1-2 (full size housing, smaller wheel). The -ex3 just means that it has a turbine outlet setup for an HX35 downpipe. It's a good "stock replacement" option.

TTT What turbo would be recommended for 24 valve, comp, dd2, dtt89? I want to keep the hx35 configuration. I'm assuming this outfit would run about 380-400 hp. Would the ksb1-2-ex3 be a good pick? Will it blow enough air to keep egts in check @ wot,5x5?
Thanks eh

I run a Blue Chip FMS, timing box and had dd2's and Suncoast tranny. I dynoed at 180,000 miles and with the full B1 I made 446 horsepower. A switch to DD3M's made 496 horsepower.

I switched to a KSB1B at 195,000 miles. I finally redynoed at 235,000 and made 463 horsepower with a KSB1B and supermentals, which should be very close to DD3M's.

Both my B1 and my KSB1B have a blocked wasegate. Spoolup is day and night differance, which makes towing a much nicer experiance as well.

 

Hey, Carcajoucummins, thanks for your reply. What kind of temps do you see when you get on that thing? How do you think the ksb1b would compare to a dodgezilla hibrid(temp wise)?496horse, holy!

 

What's a DD3m? That's a moniker I haven't seen in two years on these boards

Diesel Dynamics III "Black" - they were alot stronger then the "regular" 100hp DDIII's.

 

OH!! I know of the DD "blacks", just never saw them listed as the "3M". I was thinking that the DD3m was the super-secret TRIPLEMENTAL

Hey guys, I thought we were talkin turbos? I need your help to find the right turbo for my rig! Any suggestion would be appreciated.

 

THe KSB1-2 is a great choice for up to 425hp. Really fast spoolup,too.

I've usually seen DD2s and a Comp usually make more power than 400hp. I think 430-450 is more like what people get with enough air.

Don't know if you can have, or want, the HX35 configuration (assume your referring to downpipe) on anything bigger than the KSB1-2 (B). Rod at Wildcat can tell you.

The KSB1-2 will give you better flow, and therefore, lower EGT's than the Dodgezilla, but it will still be toasty with the comp & DD2's. I would seriously consider a KSB-1 with a new downpipe if needed.

I love my KSB1-2, EX4 but can hit 1500* if I stay on full throttle (4-6 sec) at any setting from #5 up on my box. That's empty, me & full fuel (7450 lbs) at 650'. I assume the EX3 has more drive pressure (TIP) and gets hotter sooner.

How is spool up with the -2?

Do you have any idea of how much cooler and how much slower spool up would be with the -1?

You have fireringed heads - Did you break something and what boost do you run?

Thanks,

George

 

I had a leaking head gasket with my HY-35, EZ, and DD2.5's. When we pulled the head it was nowhere near level..which is not unheard of on stock heads,: so I think that was my problem. Decided to do it right and just once...so went with the studs also.

I'm about to find out about the KSB-1. Been told by B-1 experts that I'll drop 100-200* EGT's and spoolup will be hardly any different with big enough injectors. Was also told I could loose 100 rpm max on spoolup as my injectors are borderline to "big enough".

With my present KSB1-2, spool up is excellent, almost as fast as the HY-35 (see Rod's comments above). -2 been tested as fast and faster than Hx-35's. I pull 46 - 50 PSI boost, depending on PM3 setting.

As a side note has anyone considered using a water/meth setup like the snow kit to help with EGTs. I like the quick spool of my hx35 and although I know there are some ponies to be made if I went from 30 to 40+psi, it also seems like the snow kit is a pretty neat little deal. I don't tow so I can easily count on one hand the times during each day I am able to really lay into it in 5th to the point that EGTs become and issue(1400+). Doesn't take more than a few seconds with an empty truck and comp on 3 or higher to be going waaaay over the speed limit. I also know someone with KSB1 and 130hp inj and they still have EGT issues on high settings so I'm not convinced that any single streetable turbo out there will solve EGTs rather just slow them down. PS I'm at 5500'

 

I've considered the water/meth. I've also ruled it out for the time being.

The problem with a lot of guys running big fuel and stock turbo is not JUST high EGT. High drive pressure is also to blame. In fact, high drive pressure is the main cause of high EGT!

Truth is, if you want peak EGT to be under control, you have to live with a bit of lag, more than most people are willing to live with. This lag also tends to cause high EGT when towing unless you wind the engine up to uncomfortable RPM (2400+).

More truth: if you want to tow well, you need to fofeit a little "sportiness" unless you go to twins--ESPECIALLY in high altitude.

Towing heavy in high altitude is the ULTIMATE test.
