Vq35hr 20psi stillen blower

Pro4Jackster

I just saw this. It is my car. I got the cog pulley idea from the Stillen supercharged guys on this forum. I am running the 3.2" serp pulley that comes with the kit. The rear pulleys were a 1:1 ratio and were changed out for 34T:30T setup and JTran made the idler pulley and got everything to work. Should be spinning the Si impeller around 56K rpms. It made 13+ psi on the SCi impeller at the same rpms, so I think 16+ psi is probable with the Si. Also have a 28T pulley in Ron's toolbox, but we haven't been able to make it work without shredding cog belts. It would spin the blower around 61K rpms, but I don't think it's going to happen. That setup will surely push close to 20 psi, but I'm not in a rush to make that work right now. For extra cooling, we added meth injection.

The car made 266hp w/ boltons and tune. 409hp w/ Stillen SC. 420+hp w/cogs. 450+hp when it blew w/ cogs and Si impeller and quite a bit of belt slip(15 psi @ 6500 rpms and held 15psi to redline).

We'll see how it does in a couple of weeks. I ran a 12.5 @ 114 on street tires with the cog pulleys and SCi impeller. I am a Novice.

All facts. Take them or leave them.

Also remember JTrans dyno reads lower than even other Mustang dynos, it's a relic, which is why he is switching to a new setup soon. We will all have a dyno jet day so we can compare numbers with all these other cats throwing out "big numbers", but as far as a tuning tool, it still does the job well!
