Lt4 blower swap
I picked up a weapon x kit second hand and am looking for a set of instructions before I get started. Does anybody have a set they could help me out with? Thanks

I believe some just used the Magnuson install guide being there is no instructions for the LT4 swap. Some things are different and but a lot of it relates.

so when you do one of these kits how do you address the vacuum bypass...
my understanding is that it is electronically controlled in the zl1 how do you adapt that to work ….

im trying to figure out if there is a way to adapt the lt4 setup to my eforce 2300 mine is vacuum operated and sometimes feels like an on and of switch, I'm waiting for a nitrous jet to put in my vacuum line to slow down the effect and that might work but it seems to me that the electronic control is the way to go, however I see that could get complicated real fast, so just wondering about how people with the lt4 swap kits do it..

Is there a way to maintain the electronically controlled bypass? Are you running on 93? Which kind of boost levels and RWHP do you see? |

Thanks Heater for this input.
Does it mean that your bypass operates as it does on a stock ZL1, despite the fact that you did not wire it to the ECM like BlueCamaro6 did? Otherwise, how can it work for you? What about the IAT #2 that he managed to wire up as well? I shall be following your build as it goes along...getting interested in the LT4 swap alternative. Why are you running only 91 and not 93? You could pick up some safe RWHP by being able to advance ign. timing a bot higher. |

Anyway, did you get the complete installation "kit" from ADM (Andy M)? If so, can you provide information as to completeness of the components included, meaning: Was everything you needed for the conversion included? If not, which additional parts did you have to source by yourself? What about the blower itself? Did you get it from Andy M as well? Is it a take-off from a ZL1 / CTS-V, or a Z06? Finally, how did you go about the installation? As far as I am aware, ADM does not provide a "manual", nor does WeaponX.... |

Was the use of the adapter plates and swapping the valley cover an issue requiring a great deal of DIY, or was it a straight forward job? BtW, why did you end up getting the possibly water-damaged replacement wiring loom from ADM and not from WeaponX (your "original" supplier)? Actually, I am looking for a streetable application. I am not into drag racing - just thinking of a bit more "fun" power. The fact that the blower is relatively quiet and not whining is an advantage for me as well - not a drawback. I believe that using (maybe) one size smaller pulley, LT4 Injectors & LT4 FPs (+LT4 Fuel fittings) on 93 can get me to around a "safe enough" 560-580 RWHP, which is my ball-park goal. Idea is to also avoid having to go into the motor, in order to replace Pistons / Rods. |

The only reason I could think of that the LT1 with a blower produces more power than an LT4, would be the higher C/R of the LT1 (11.5 LT1 Vs. 10.0 or 10.5? LT4). Why would there be a difference in heat (lower for the LT1 with the exact same blower mounted)? Why did you put a larger pulley, rather than leave the stock LT4's 2.5? Finally, who tuned the ECM? Was it performed on a dyno, or did you log on the street and had it sent to the tuner for mail tuning? |

The LT1 has a much bigger cam too.
I went with Pray Procharger setup (with heads, cam tune), but would have been just fine with ADM, price seems great.

The stock pulley of the LT4 should be avoided, since it is too small (spins too fast) when working on the LT1. So when you get the kit (Incl. Blower) from ADM (or WeaponX too?) they supply the blower with the larger Pulley already installed on it? You are lucky to have a knowledgeable tuner on LT Gen5 ECMs and engines close to you I think that I would have to rely on remote tuning when the time for my job comes. I do have a couple of dynos close by, but I don't trust local tuners on the LT Gen5 platforms (yet). There are 2 tuners around who are very good on LS setups, but I am looking for experience and perfection on the LT/Direct Injection setups. Unfortunately this place is "ruled" by EURO Import material (VW, BMW, Mercedes, Porsche, Etc.) and less GM/Ford/Chrysler. But it has improved slightly in the past 2 years with an inflow of C7s, SS, ZLs and CTS-V/ATS-V machines. |
