Preparation for the STILLEN supercharger

Zsteve

But if you can spend up to 7K on the kit and labor then how much would it cost for the pully and all to get the kit into its max efficiency to begin with? I can see the advantage of being able to upgrade easy just cant see starting under its efficiency, but like you say everyone is different and do things differently. I just hope I can get my money from the Army soon so I can buy one of these kits.

I completely understand what you're saying but I don't think I've done a good enough job explaining it to you.

Let me think about how to properly write this so that it makes more sense to you.

Long explanation short...It's not that the blower is starting under its efficiency, there is a lot to take into consideration on this and I need to elaborate on that.

let me fix that it won't cost much for the pulley and a new tune to get the vortech into it's efficiency range the problem is can your stock engine handle 15-20 psi with over 700hp without going bang. thats why you start with small power on a big blower. then all you need to really spend cash on later is your engine instead of having to buy another 2500-3000 compressor (vortech pricing)

Edit: there now kyle can relax in the morning when he gets back on his computer. So the kit fit under our massive strut bar?

Yeah, given the tuning is solid, I wonder what the stock engine's limits are as far as how much boost it can take reliably on pump gas?

This is the Holy Grail of questions posed in every revision of the VQ as well as every other platform that is modifiable on the planet. The simple answer is - no one knows. We thought we knew with the DE after 2-3 years of development on it, but there was always the guy who lost a motor on 6psi which was considered safe and the guy who had 30+ passes at a drag strip on 14psi before the stock block let loose.

The honest truth is, when you force induct a car that wasn't engineered for this application, there is no true "reliable." You take a huge risk no matter what. I have heard it said many times - "Fast, cheap and reliable; you can only have two." I don't really believe you can have cheap and reliable, though.

Eventually when I get bored and have some extra loot laying around to rebuild the engine I'll give you an exact number hahaha.

Im pretty sure this blower is already in its efficiency zone even with the Stillen CARB kit. Remember guys that the CARB kit is already up 140whp up on their baseline (420-280=140whp) per Stillen's preliminary dyno numbers. Its not like they aren't making good use of the blower, its just that it has a good bit more room to stretch out it's legs after that.

So the guy that just wants a mild HP upgrade and never wants to build the motor for high horse power just ends up with a blower that is out of the efficiency range? Why not offer another blower option? Makes more sense to me.

Assumimg Stillen uses the Si trim supercharger, the compressor map leads me to believe that this supercharger starts off with a high efficiency already. However, as you increase the boost and airflow with this unit, you still have excellent efficiency.
