Well, I can honestly tell you I hated mine after dynoing at 440whp and still getting raped by a 400whp turbo. It's been a few years so I don't remember details. All I know is that at that point I realized that a turbo made better use of power under the curve...

 

Understandable... I understand the pros and cons between the two. Also i have an 05 and was curious what the safest hp level would be on say an Emanage or FIC. I would love a Kpro but that would be further down the road. Unfortunately I live in a OBDII scan area so EMS is out :-( also i would like to stay stock engine comp etc... And the last question is what's safer on drivetrain? I've heard turbo because you have to build the boost back up after a shift.

 

After a ton of problems with turbo kits that myself and a friend were installing on both of our cars, I would rather have gone with a supercharger kit from the beginning, considering a mutual friend of ours is making close to 600 whp on his SC.

As far as drivetrain safety. I would think a SC would be safe because it gradually builds boost as RPM increases, you don't hit max power until close to redline, with a turbo you can hit full power as low as 3000 rpm.

 

People start to see belt slip with that much boost on an SC.



Once you get into or around 400RWHP it becomes a lot more about getting the power down than how much power you actually have. 400rwhp is kind of ridiculous for a 2700lb car on the street.

A turbo will have more power in the mid and low range than an SC yes. But if you are tracking the car or driving it hard you will have the car at higher RMPs to take advantage of vtec anyway. in many ways having an SC keeps the driving experience of the stock S because you have to work for the power, you just get a lot more of it. However, with the 9K redline and the 6speed transmission it is easy to keep the car in optimal range for the SC to make boost even when shifting. The only way I would see the low and mid power range coming into handy would be from drag racing from a dig. However the s2k diffs are week so you can't launch the car anyway and if you wanted a drag car you shouldn't have bought the S in the first place. You might see some advantage with having mid range power on some autox courses but if you are competitive in autox you probably wouldn't have gone FI in the first place cuz it would have thrown you into a difficult class.


I'm not saying the SCs are better than turbos I just think people are bashing them for the wrong reasons. As I said before in this thread people who want more than 400rwhp end up getting to the blowers limits and getting a turbo. weather you are running into belt slip issues that tend to start once you get over an 11PSI pulley or make enough boost that you are running the blower so fast that you are pushing it above it's efficiency range.

Turbos are arguably more better for higher HP applications with the S. However, at the same time blowers are arguably better for lower HP applications. After all I don't see many people with these bigger turbo kits making 300-350rwhp. Sure you can get the greddy kit but as someone mentioned in thread it isn't of the best quality not to mention possible heating issues.

Because of this you will normally see the flowing:

up to 350rwhp = SC
350 - 400RWHP = Grey area
400 + rwhp = Turbo

There are of course exceptions but generally most of the SC set ups that are significantly above the 400RWHP mark aren't your basic comptech and vortech kits. And at the same time most people aren't going to spend a ton of money on injectors, stand alone engine management, exhaust system, and go through all the time and trouble to run 300rwhp with a turbo (this excludes the greddy, but it all honesty it is outdated and was commonly a starter kit where owners would gradually replace all the parts and turn it into a better kit and make more power. There didn't use to be that many options for full turbo kits and people commonly made their own).

Both applications will work well. It is just kind of ridiculous when people blame their SC when they are obviously asking their kit to do something it wasn't meant for (not saying that anyone in this thread is just in general). Even if you go onto SOS's website, I don't think they recommend running a smaller pulley for the comptech kit on an AP1 than the 11PSI pulley. The smaller ones are for the AP2. Most of the pulley that people are throwing on aren't meant for a car that redlines at 9K.


my $.02

 

I think Im one of the few people who was turbo (+400whp) and decided to switch to a S/C kit. Even Science of Speed was like "why are you doing this?" on the phone lol
After 2 years of being turbo'd , 2 blown motors & lots of late nights working in the garage I said f@#k it. Better off with something a little slower and a whole lot more reliable.
With a S/C I now have the option of doing track days and other fun stuff too. Dont get me wrong, straightline speed is awesome, but to make this car truly fast you need a lot more than a good turbo kit.

 

I just wish there was a good 400+/- roots type blower for these cars. There was the one SOT kit but only was good for 300-350 MAX which is not enough imo. A kit like that but 400whp and 300ft lb tq from idle would be perfect!

 

Expensive upgrade for belt slip. I would have just tightened it properly and beat that Camaro SS

 

I would love SC for the simplicity/reliability over turbo, but the thought of any kind of substantial numbers by 4000 RPM (as delivered by the PTuning kit) is almost too hard to ignore.

 

Im totally with moddiction. If only there were a mp90 kit!

 

I gave it up because I was tired of replacing differentials Boost on the track with an ap1/ap2 stock diff = disaster.
