well not much more would be a bit different if say you didnt owe anything on your car but its only worth 20k. An isf is still in the low 40's for an 08. A supercharger will only put you back 5k reasonably with a spark/fuel/meth tune with a mapecu and I can almost gurantee you'll be as fast as a stock isf.
20K or 5K?
MAPECU works in both closed and open modes if you wish. So it's definitely doable. Pepos from greece is running the exact same setup on his 250 and is claiming a 100bhp increase.
If he can do it with a 250, we can do it with a 350. In fact, I'lll be installing one within the next few weeks for a try at 300whp, then I'll supercharge later. You are still limited by the high compression and you wouldnt get the great is-f transmission, but there's something to be said about having a fully tuned, supercharge is350. It's just unique.

Even his stock numbers don't match up with normal.
I don't doubt anything he has said, but I have major doubts about the place he gets his car dynoed
Especially given his numbers don't match up with the hp-per-psi numbers of anyone else who has done/tested a supercharger on the 2IS.
Everyone else runs 5-6 psi and picks up 50 or so hp... which won't catch you up to an IS-F.
and that's usually for 5-6k.
Adding a tuned MAPECU setup and meth injection spikes the cost up further (and the complexity a fair bit too)
As to your cost #s... if your IS is only worth 20k there's something wrong with it... a good low-miles IS350 should be in the high 20s/low 30s still. Looking on autotrader I see an IS-F with 35k miles for $36k... another with 27k miles for $37k...2 more for 38k...
If you can get an IS-F for 36-38k and sell your IS350 for 30k, you're paying 6-8k for a better transmission and 108 hp... and your warranty remains in place (with the option for extended)
Versus paying 5-6k for a bolt on SC for 50 hp and the same transmission...and no warranty on powertrain if anything goes wrong.

SOrry, I was basing it off of trade in. My car has 82k so its not exactly a spring chicken anymore. Id think there are quite a few 06's out there that have a few too many miles to make it a good trade up to an isf without expending more than 10k.
HKS could shed some light on this. That system he wired up SHOULD be very similar to what a mapecu could do as well. I'd like to see his dynos now. Although he cant fine tune it himself, its the best thats been attempted if you consider pepos results subject.

NOS - Fun easy cheap, HP is all in 1st and 2nd gear. No noticable power gains after 60mph
SC - Fun, Noticable power everywhere in the powerband. You will outrun stock IS-F's after 60mph all the way to the speed limiter (155). The HKS SC has changed my car completely and after having both I would go back and pay 8K for the HKS SC over buying an IS-F all day everyday. Just the fact that you hear the SC screaming at 70mph just sends chills down my spine and gives you a rush the IS-F can't do for me.
