If the Engine is studed 18* would be great .. also .. do a cold re-torque before you start getting too far invested .. if he didnt do any re-torques .. this is the time to get it done before you end up with a leaking or blown HG .. Insurance policy :tu:
If its not studed... Get on it .. dont touch a think until its studed !! :td::nope: |
Motor has been studded.
The pump is at 21*, thinking I will change it to 18*. Should I take it down more then that? It has 191 DVs Installed a DDP AFC spring which is about 1/2" longer then stock and set it to be full open at 30 PSI with shop air. Smoke screw is just touching plunger so it is at zero. |
Sounds like playing with tiing and some AFC tuning should help .. let us know what the timing comes out @ and if that helps your Spool/Vleocity ... :pca1:

EGTs are better then they were and I have about 1/3 as much smoke as I did before. I still am not impressed with the spool up time which is 1800-2000 RPM.
Has anyone tried a Blaylock variable vane turbo on one of these trucks? I would like to see it spool at a lot lower RPM. |
1800 is great .. thats where mine spools .. I also have a 1700 stall converter ..
factory TC is 1900-2100 rpm stall |

factory TC is 1900-2100 rpm stall The owner of the truck is not impressed with the 1800 RPM and is pushing me to put a single on it. If I could get it down to say 1500 RPM I could probably convince him to keep them. When your pulling it like he does, it would sure be nice to have something on the bottom end. Maybe we are expecting to much out of twins. What is normal spool RPM for a HTB2 & S400S062 Turbo setup? What are others seeing with their twins? |
most guys are running the he351 or a 35/40 with the HT3b .. I will be attempting to do a 34/40 HT60 .. oughtta be fun .. will see ..
the primary could just be to damn big .. might try a HX35w out of the box with the HT3b and see how that spools .. Just a thougt .. and its failry cheep too :humm: |
