Theres alot more to it than that. Injector position and angle is incredibly important, let alone how long the pipes are, how thick, etc. I'd read up on that **** first before you start whipping **** together. Just to at least get some idea on what to look for.

 

I don't think you understand. I'm talking about an upper intake manifold, that goes on top of the supercharger. It would be simpler (but not simple) than it would be on any other sort of RX7, because you don't have to worry about the injectors (all injectors are aft of the supercharger, for obvious reasons).

 

After doing my setup I took my car to portland Or and put it on a Dyno to be tuned. So this chart is during a tune. http://www.camdensuperchargers.com/i...rides/Dyno.jpg After the tune was complete I pulled my car off the Dyno drove it on the street and it didnt run worth crap, so I still had tuning issues. The tuner said that my car has no problem going to 11000rpms. Anyways heres my chart during that tune if thats what your needing So having the microtech, it had to be tuned the rest of the way by driving it. This is also only with 5lbs boost . Im not very rotary smart here "just learning myself" but I do tend to agree with you about the injectors on his car.

Does weight have anything to do with his car sonic? 2nd gens weigh so much more than 1st. I drove home in Atkins 2nd gen supercharged car from sevenstock last year when it was running at its best, and I was very impressed.

Wouldnt the rotary world be boring if we had the same setups

 

When I first considered what engine to put in my car I looked at some numbers to see which was best for this setup. Either a 4 port or a 6 port. The difference was hardly noticable. So I went 4 port with turbo housings. 6 port having a bit more. I have a lot more mods on my little car than he does. Yeah they sure do like the high rpms. Im thinking of Dynoing my car again since its basically all tuned in as close as it can get. I think what I will try this time though is to put the 11lb boost on my car and then come back and show you all.

I think he will get great pleasure out of his car with some more mods.

 

Then why'd you buy the kit? Wasn't this the whole point of the kit was to get the mani and setup so you didn't have to custom make anything?

 

well SonicRaT. in the case of your friends thinking they can get 275 by just bolting on, i'm glad you changed there minds. cause how ever they thought that, well it is false. cause camden web page states around 176. so with the thread starters UNTUNED dyno, he's where camden says he should be. if i bought something knowing what it gives and it gives me that and maybe a little more.........well, i'd be happy. and i would expect others to happy for me. but obviously this is a public forum and everybody's got opinions(you know how it goes) and most of them stink. so instead of being happy for someone and saying good job, hope you get a little more, they just gotta let the whole place stink up. i'm interested in what he pulls. and hopefully he's a good sport about it and still posts the results.

 

That claim is for use with stock injectors, I would pray to god people would at least 'bolton' upgrade their injectors at the same time. My point was, with the larger injectors, and exhaust, there's a 90% chance 275 isn't going to happen. Camden says he should be higher due to his upgraded injectors

 

will post the slip to ya all later. gil, ps i agree with ya sonic, ive done everything they have told me to do with that sc, soooo we shall see later today.

 

Nice look graph codeblue, nice to know that it almost maintains perfectly the curve of the n/a, just gives it the little extra. Was expecting to see maybe a bit more torque in the lower RPM range, but still damned nice.

 

Its not just about the money. A big part of of the reason people are compaining is because you dont get what you pay for. The product should be making more power. Yes they spent a lot of money on R&D, but obviously they didnt go a good job on adding a lot of power. Why should they charge $3k for a system that adds a little bit of power, just because they did a crappy job on it?

 

Gotta love all of these cars....
Drew: FUI I have 87-88 turbo11 rotors and rotor housings.
Sonic: Give me time and will get a bit more out of my little car.
All in fun

 

In my opinion if I owned a 2nd gen car I would not supercharge it as much as I would a 1st gen. I would prefer to go turbo vs the supercharger. The weight on a 2nd gen is much more than on a 1st. As for cost. Its no object when you want to be different.

How can you say just a little power added. Ive gained over 110hp with my setup. Thats just with 5lbs boost.

In time I will gain more if I decide not to have my car as a daily driver. As Im sure RX7FROMCAL will want as he gets use to his blower and wants more.

 

Will you also tell us how much you spent on the WHOLE setup, including your injectors, and microtech and all the other little things in addition to the $3k supercharger. So what HP are you upto now? Also your 110hp increase does include other mods such as exhaust and intake. I could make much more power for less. I probably do, I just need to take my car to the dyno.

 

Well, that's not really a valid statement. The setup you have should easily make 180 on an n/a without the charger, so you can't really say that. And who you callin fat!? My s4 sport weighs in at 2420lbs, i thought I was doin good damnit!

 

Man you guys shoot anything down which is new. You wonder why new parts are scarce and expensive.

I think a SC FC would be cool. I planned on doing this until I blew my NA motor.

BTW 3k for 170+RWHP isn't too shabby.

I've spent over 6k on my turbo conversion. As of now I've dynoed at 180 RWhp/tq.
Now a downside to a supercharger is that it's more of a fixed rate HP while turbo's can generally be over boosted much easier to high HP levels. Although a SC does have a more predictable curve to work with.

 

For the whole setup 7in supercharger, microtech, handset, manifold, High performance fuel pump, injectors, throddle body, marine line, etc and other things included not on this list. $3000. $500 labor. I know people can make much more power for less money, but its different and new. Thats the point of all this. Its what one prefers. No one says my car or any other supercharger car can beat every car on the street. That would be a false statement. Alls I know is that my car has some great low end power for what it is. Ive feel that its been well worth the money spent.

Saying that they give hardly any power is wrong to say. They may not give as much power pursay as a turbo, but different mods for different power.

I know someone that has a 13b 9in supercharger that does over 600hp. Not bad for a blower. It is a Camden blower.

I have decided after all this to put the 11lb boost on my car just for a Dyno to see what I can get as far as HP is concerned. I will try for next week to see if it can be done. Or right after Christmas.

 

11 PSI of boost from an SC should pack a whallop in the low-mid range and make launching the car a whol lot of fun!!!!!!!

 

I would like to hope that people that have DONE the work will post with their experiences, but guessing at how much a project will cost to get done is just pure speculation at this point.
Just because you can get it done due to your resources doesn't mean everyone else will...

Seriously, can we drop the bitching and let the people who have direct experiences post?
There's too much crap in here that muddies the intent of this thread.

Your not fat....your just heavy. lol

 

dyno at 173rwhp 139.86 torque tuned fuel ratio perfect after we were done, this is the best its going to get, with what i have. next to pull the cat and run a straight pipe, that should help. well here ya go people tear it up . cya all the pic on the left is the first run , the one on the right was the last.[/img]http://www.cardomain.com/id/rx7fromcali[img] click this page 8 for bigger pic.

 

I think you should get some kind of intercooler going before anything else.

 

it doesnt require a inner cooler!! its a superchager, not a turbo.

 

...

Any boosted application requires an intercooler eventually!!

The more boost you run, the higher your intake temps will get and the less power you'll make. If you think just because it's a supercharger it doesn't require an intercooler then well, fine don't do it.

If you run a turbo at low enough boost it doesn't require an intercooler, just like a supercharger at low enough boost. But as far as I heard 8psi on the camden unit is about as much as you should go without some type of cooling, either air to air, or air to water, whatever.

 

I would have assumed that an SC wouldn't need one do to the fact that it is not directly or indirectly interacting with the exhaust.

Why would the SC air even get hot? This is a serious question, as I can understnd that on a Turbo Exhaust gas is spinning the turbine blades, thus heat is being transferred to the turbo housing directly.

anybody?

 

hey. congrats on the dyno. looks good. nice lines at the end. steady. who cares what they think, be happy you got t=what you wanted.
