Stillen FI Kit Review

SC at the limit of your engine will produce less power than an tt kit at the limit of the engine. Simply because it takes power to run the sc. I think we're sacrificing around 5-7% power with the SC.

What I've heard, from several sources now, the limit of the what the car can "safely" run is ~500whp. Taking parasitic power loss on the sc into account, we're looking at around 465-475whp. To be safe I'd put the WHP level based on something between a dynojet and a mustangdyne. In other words, by my guesstimations, the Stillen SC kit should be able to push around 500whp on a dynojet and 450whp on a mustangdyne on the stock block. Translating that into what we know the kit makes at certain PSI levels...I'd say we (Stillen kit owners) can safely run 10.5 psi with good quality 93oct gas.

There are pros and there are con's to having a turbo vs sc. It shouldn't all come down to power like you guys are making it out to be. Peak power should only account for like 25% of your buying decision, if that. Specially so when the difference isn't that big at the limit of the stock block. It all depends on what you want to do with the car too. I don't seem to understand why turbo's are so much cooler, is it a status thing? That you spent $5000 more than I did for 25-50 more whp?
