Have you tracked yours? What times and mph did your downpiped, MBC@14psi VR4 run? Short times? 1/8th mi times? Howcome I don't see more dp and MBC@14psi VR4s running 12.8s@xxxmph???

Im going to Sac in a month. I just have to pressure test and change out my wires and plugs. Well times for a 3/S with these mods range (obviously depending on driver). Its probably between 12.7 - and no slower than 13.5. Im a decent driver, but we will see. I asked the pink 10s auto FD driver because I was curious as to how much an auto would affect E.T. on an FD

I guess you don't troll 3si then, although with just a mbc and downpipe 12's are not common. Low 13's aren't uncommon though.

Generally, it takes an intake, some sort of b/c and a downpipe to get into 12's. A clutch makes it much easier. A downpipe is huge for the vr4 as the stock one was horribly engineered. Also, certain downpipes do different things for vr4. Some replace pre-cats, some don't. If you gut the pre-cats it makes a big difference also.

Not too much. They are about the same, just a little slower start. I should run 13 flat at stock boost, hopefully low 12's after the upgrade.
