The point is that he's running 10 psi and only gained ~35 rwhp over a stock s5.

And actually a stock s5 (like his) Turbo II runs ~170 to the wheels, so he's really not... Plus that's a STOCK TII, throw exhaust on and they're easily past him.

I've talked to Deena about her sc first gen about all this, she uses the camden unit. She really thinks that something is wrong here after reading through this thread and rx7fromcal might need to resolve some issues, possibly. She said she might post in here, so don't take anything I say for fact until she says her piece, if she wants to. But I can tell you hers did much better with the camden unit than rx7fromcal did. She said I could drive it one of these days to see for myself, so I can't wait

so in effect he's actually turned his n/a into a stock turbo2? whats wrong with that? i think thats pretty good. and how long did it take to bolt it on , change the pulleys and belt, and run an oil feed? probably alot less time than puttin on a turbo.

i truelly think the whole point was.......... he's happy with his supercharger!.

Yes, codeblues car is pretty impressive.... But lets compare to this car.

Codeblue has the following:
Standalone (LT8)
TWM 48mm throttle body
Upgraded ignition/coils
full true dual exhaust
and a street port

Not quite an even comparison to a stock TII (considering the above could get you a stock TII!)

S5 TII #: 200bhp 196ft-lb

Now, compare to a similarly setup N/A, and again, it's about a 30hp increase. However, his car still is damned impressive!

It took me less than two days, that's more than I can say for poor snub and his SC install

If he's happy then good for him. But over 3,000 dollars just to get to a stock TII power is, well, a rip to me. I'd rather spend the money on a TII motor/driveline/computer/harness and have a much higher power possibility.

He should've seen much greater gains than what he did. Deena with her first gen is putting down what 210 hp to the wheels? And that's on a 5psi pulley...

Just for some info, her engine is a TII block (4port) and the port job is mild. Not sure on what rotors were used, she'll correct me if I'm wrong here.

But that just even shows more with the 4port that she still put down 210.9

Because you specificaly said it made as much HP as a stock tII. Also, the torque was 145ft-lbs (as last reported), if you check out the dyno section area, you'll see N/A's with similar numbers (135, etc)

Might I ask who you're saying has stock injectors? Last I looked nobody does. Furthermore, you mentioned Codeblues car, and the original posters within the same paragraph, determining which you meant was left up to assumption, however it's still not really better than a stock TII, regardless of which it's compared to.

Originally Posted by kettlman

When have we ever attempted to give him a bad time? We haven't said one thing negative or mean about the poster, we're simply making arguement for the people who actually are considering this, we're all for the original poster, it's not like we're calling him an idiot for spending his own money or something stupid. This is why this thread has gone on for so long, people dismiss arguement against a product as trying to just ruin the guy who bought it.

For snub: You earlier posted your boost pattern, which would come out in psi like the following:

4psi by 2.5k, 6psi by 3k, and 9psi at 4k

Is it just me, or does that appear to be about the area where a turbo spools at? Just trying to get a comparison, I know in my turbo I see full boost by 3.2krpm, anybody have any feedback?

Did you read the part before that?

If he's happy then good for him.
I don't care what he does, his decision, I'm giving my opinion


The POINT I and others are TRYING to make is that something seems wrong here! He should be making more power! Maybe it's a cooling factor, maybe its tuning, who knows! But Deena puts down 40hp more at the wheels with a 4 port mildly ported motor and 5psi, I think something is wrong with his setup.

the sad thing is that i read all the posts. and it does seem like you're putting something down that he is so proud of. why ruin that for him. yeah, you might not think that you're being negative or mean. but putting down something he just got , well thats pretty cruel. you might not notice it. maybe thats why he hasn't posted much on this thread. who knows. i'm sure he's waiting for the other dyno when tuned. so hopefully you guys can get off that 170 something kick. but even on the camden web site it states approxomatly 176 or so. so he's getting what he paid for. with all the "arguement" all you're doing is saying that he was stupid for buying that supercharger thing and he could have got more for his money another way. and thats just plain wrong to say to someone.

You are forgetting that this is a public forum, with impressionable people who take into consideration results from people, and more often than not, these results are misunderstood, and people have little to no information about how it stacks up. The sad result is, a lot of people think this thing is capable of some serious power (if you don't believe me, you should see the PM's I get about people asking me questions about supercharging them), I'm not knocking supercharging (I've got my own supercharged car, no need for that), I'm just pointing out that it's a very minimal gain compared to the vast lis tof other options as it stands now, and from there everyone's just argued every angle imaginable. Now, I've talked to a LOT of people about this kit, specifically because I seem to always pop up when it's mentioned, and people seem to like to hear my thoughts about it before hand, I personally know 6 people who had money in hand ready to buy this kit based on the idea they could get 275hp out of it, and everyone of them has thanked me that I convinced them to wait and see first. So, *shrug* It goes both ways, some people like the truth and having the information available, others don't.

well, there you go then. well said. i'm sure someone can get 275hp out of it if they knew what they are doing. but obviously you don't know how to get that power out of one so you're knocking it down. easily done. i'm sure not many people can get those numbers out of a box. but with a little work and knowledge you can eventually get there. i will agree that for the price you can get alot more. hell i could get 400+ for that price. but time will show what the superchargers can do. so hopefully he will post his results tomarrow so we can see how it went.

I don't know how to do it? I've got more 6ports over 300hp than I can fit in my garage. Camden says the max psi is 11.... It's hard to imagine them getting to 275rwhp at 11psi.

I had a chance to ride in codeblue's car at Sevenstock. He put down 211 rwhp but he has since gotten a little more out of it with better tuning. I think he hit that number at 6 psi. I can't quite remember. The car was fun. It had tons of low end power. Off idle power was great. What was a strange feeling for a rotary though was that it didn't keep pushing you back into the seat as rpm's rose. It's like it gave you an initial kick in power down low but that was it. It felt alot like a Mustang GT power curve. The car was still decently quick but obviously not the fastest on the road. It is a very fun setup though. I'd love to have that as a daily driver or as an autocross car. Is it worth $3000? If you spent $3000 on the system and are satsified with your purchase then I'd say it's worth it. Personal satisfaction is all that matters. What others think don't. There is always another way to do it, a faster car, and one done cheaper out there somewhere. It doesn't make any one of them less viable or a waste of time.

Codeblue does not have a true dual exhaust system on his car. At least not as of Sevenstock he doesn't.

Yep, that's the way the boost goes. Yep, that's the way (or maybe not even) the way a turbo is going to go. The thing is that it relates directly to the engine RPM, so whenever you plant your foot, that's exactly how much boost you get, right at that moment. It's not going to be as fast as a turbo, it's just a little different.

First off, facts are that Turbos do and can produce more HP and Torque than a Supercharger. I’m not disputing that. But to say that it DOESN'T improve the power levels hardly at all is incorrect. What its all about is a matter of preference.

I know how this guy feels because when I first started modding my supercharged car I was very frustrated with the numbers it was giving me. I honestly think that he should be pushing a bit more HP with his setup, and tuning could be a factor. The more mods the more HP. But he did increase by 30.

Its so hard to describe the feeling I get from the Supercharger. I love the low end power. Its a low end torque monster, and yes the price is crazy, but when you have bucketfulls of money...hey ya gotta spend it on somethin....lol

I dared to be different. Ive raced turbo cars and smoked them hands down, and yes Ive even been beat by a turboed honda running 25lb boost.

Its all about more and more mods and more money. I know I can produce 270hp if I change my injectors and change my boost to 11lbs, but what I look at is the longvity of my car used as a daily driver. The supercharger is just easy and low maintenance. They both have their good and bads.

Anyways good luck keep us informed as you go along with this venture with your supercharger. You will be happier as you go. Catch me on aim.

YES Ddub soon Im coming to visit you when you have time so that you can post on how the blower feels compaired to the turbo.

I think it was well worth the money I spent.

Yes more improvements have been done since sevenstock. When I got home my tuning was so far off I surprized the car even ran. Its a fun car to drive, Im happy with it. Coming soon as Im planning on more changes.

also remember this is a 6 port engine.. so make sure you take it up to high revs on your next dyno tune, doesnt the actuators for his 5and6ports open 1 at around 3500rpm then the second one at around 5500? thats where all the power should be. driving a 6 port motor without working ports is just brutal. its like taking the Vtech out of a honda! NO top end at all! so if like everyone is saying, the SC delivers low end torque, then he has those ports to open up and help out his high end. if this girl you guys are talking about hit 210 on a 4 port, then he should be able to beat that!!? sorry if im mistaken.

A Whipple 2200. Seriously. I've setup various eaton units and a whipple, and it's just a lot better efficiency. I just don't believe the efficiency of this unit is capable with the common belief people have for it. For a couple of numbers, an eaton m90 on a stock port motor using the stock TB will put out around 270rwhp w/213ft-lb torque, the whipple was last reported back to me at 320hp, I only got to design that and lay it out, didn't get to tune. Now, what is curious to me is the following. A) he's running 11psi with minimal injectors and only getting 171hp, now, even with tuning, it's not going to force any more air into that engine, and the camden unit isn't meant for anymore than that... Now, when you throw a different throttle body, do some serious porting and run a standalone that numbers going to be quite a bit better, how much? Codeblue can tell us! (What's your boost like if you don't mind me asking, similar to what snub posted, RPM to boost?) I'm just curious as to the addition of only about 30 on a stock at twice the boost compaired to a modified running half getting 40+. Again, you'd be amazed at how many people I talk to who have had money in hand just licking their lips to by this expecting 275rwhp from just bolting the kit on. Those are the people I'm trying to deter. You guys with the money and who want a perfect curve and etc, god speed and good luck, and I'm happy there are more SC cars for me to chat about if I meet any of you, but I also don't like watching people dive into something so unknowingly, thus why I waste countless ammounts of time questioning and arguing.

To the guy above: Please research the subject before posting, I know you have good intentions, and I don't mean to sound mean, but the VDI & aux ports are removed when installing the kit.

I'm actually considering doing that(20B project = $20k at LEAST, remember). I'm interested in going standalone, porting the motor, and installing a custom intake manifold with a new throttle body. I think that wouldn't be too hard to fabricate, as you don't have to put anything on the intake mani. except for the air temperature sensor (injectors go under the charger, remember) and a custom bracket for the throttle cable.
