Engine/Transmission (1998.5 - 2002) HTT KillerB into twins

[FUL POWER]

Has anyone took a HTT killer B which is a 64mm intake and a 14 exhaust and made a set of twin out of it. Would it work by using the HTT as the top charger and using another for the bottom.

It could be done. I dont know if anyone has done it with that exact turbo though.

I would imagine that it would need a pretty large bottom turbo... Big Brother, HT4C, or something like that.

TDR member SRadke just did this or is almost finished. He's mostly on the 3rd gen forums. He has some pics in his gallery too IIRC.

I did it. Hasn't been running long but so far I'm happy with it. Used an S400 on the bottom.

Where did you get the piping fo the set up, did u make it or buy it. How is the spool up with the chargers and what pressure of boost are you running. If my pulling class let me i am going to try to make a set. but most likely they will not so i am going to have to go with a bigger charger

 

[SRadke]

I made all the piping, brackets, oil lines, etc. Just bought a bunch of exhaust elbows and started to cut and fit.



I'm currently running a 100% stock head so I've got the wastegate opening up early to set max boost about 50 lbs. After I get some studs and possibly o-rings I'll open it up to the 60's or beyond. Before I got the wastegate set where I wanted it I had no trouble pegging my 60 psi boost gauge.



Spoolup is down over the Killer B2 as a single. Down more I believe than I lost going from the stocker to the Killer B2. Noticable lag but still drivable with my handshaker. I intend to get my box reflashed to the twins program to gain some fuel down low.



I have to move a 12,000 lb log skidder on a goosneck today so we'll se how she tows

Nice work Scott! I am still patiently waiting for Olee to finish mine



Did you TIG or MIG weld the cold pipe? I still really want to make a set of twins from scratch just for the experience. Still trying to gather as much info as I can from the guys that have done it

 

[SRadke]

I mig welded most of it then got inside with a pneumatic die grinder and polished out the dingleberries etc as I went along. Like you say, I really did it for the experience I had enough power with the single.
