Stillen Supercharger reliabiity

SS_Firehawk

I spent $5500+ install for about 50whp. Pretty sure a SC will outperform that dollar per hp quite easily. Keep in mind, most people with FI spent money on supporting mods also. The kit may have cost $6k, but they also may have purchased a CBE, HFC or TP's. Most also do their own custom tuning which is another expense. That 6k all of a sudden looks like 9-10k after it's all said and done.

I agree with this, however, if you talk to Stillen they will tell you that their expected 390-420 whp is with the SC kit only (includes CAI). They actually advise against up front addition of headers, HFC's, exhaust etc, as those things complicate the tune.
In that case, other additions, are unnecessary, and purely per taste.
I have a NISMO exhaust because I like how it SOUNDS, and LOOKS.

SS_Firehawk

I was quoting my Delta from NA mods, not FI. Stillen's tune is trash, with or without HFC's exhaust, whatever. All I'm saying is what most guys here are doing. Modifications to your exhaust will gain more horsepower 99% of the time over stock in NA or FI, it's not just for taste. How did Shamu push 450whp with PPE headers and stock Nismo exhaust if it's just for taste. How did he improve that by 30whp when he replaced the Nismo exhaust with the Litespeed one? Yes, I'm sure it's been retuned, even outside of that, it's a considerable improvement. I bet Stillen would sing a different tune if you asked them if it's okay to add their HFC's and CBE to their SC kit. All they are trying to do is simplify the process for the masses. That doesn't means it is the better way to do things. Please don't take this as me being brash Iron, because your statement is fairly accurate, I'm just expounding on the whole topic a bit.

SS - I did misinterpret your initial statement. No doubt this tuner stuff can turn into a bottomless pit no matter what road you choose - SC, Turbo or N/A. I don't really know exactly how Shamu got to 478 other than the 9psi pulley - but I sure would like to know, and I am sure I will find out - slowly but surely over the next 3 years.

Still 395 is such a big gain over my stock (with NISMO exhaust) 274 that I am quite happy for now. I still have some work to do on my in car sound system so any further mods will be pushed back likely until summer 2014.
Bottom line - I love this car - and the crap we can do to it to make it even more fun.

Yeah, by the time I'm done, I'll have $18k sunk into the car... Not including rims, body work, or interior mods. Busy paying it all as we speak. 395whp would provide plenty of hooligan fun. I justified my purchase to my Wife by saying I have to keep up with the Jones's (Porches, Mustangs, Camaro's, and Corvettes). Better than buying a new one because I wanted more oomph. The other part was to help get the Twin supercharger kit out the door so we can finally get some results! Guess it's my way of giving back... by being a test dummy.

SS - Nice that the wife gives a s**t about keeping up with anyone. I for one will be looking forward to your reports on the GTM Twin SC set up. Looks amazing, and looks like a very involved install.

SS_Firehawk

Luckily I won't be doing it. Kinda wish I was there though, love learning. I think this has to be one of the most expensive ways to get results lol. Sometimes FI makes us do crazy things.

Stillen gear arrived today. SC kit and a 25 row oil cooler. Intake tube goes off to the powder coater tomorrow. I am going to do a little paint work on the intake plenum while waiting. Hope to get it in the shop for installation by late next week.

i have the kit, and it is reliable as long as you dont kill it all the time, i am wondering what the best tune is for it, i have the tune from stillen on it and it runs very rich. so i was wondering if a better tune would deminish that and get rid of the check engine light? and since stillen is very conservative, if a good tune would feel faster?
Thanks guys!

Not to bad mouth Stillen, but all canned tunes are pretty meh to bad, GTM's canned tunes are not very good either. They are a means to get the car running, very conservative to protect the kit/engine, and that is about it.
So for a better tune, I would look locally at dyno tuners in your area (you are looking for uprev tuners). They can usually fix anything software wise wrong, so running lean, CEL, etc. are able to be improved upon along with giving the setup a little more kick while still protecting it.

The tune on my car is very conservative and I gained a ton of power over the Stillen tune. My car didn't come to life until it had a custom tune.
