code blue has a new charger pushing more boost now!

BigJim

how hard would it be to fit the 86-91 NA kit on my GSL-SE with a street ported 13b? Or would it be cheaper to go a custom route?

CODE BLUE 2

The car was dynoed at 211hp after we had changed the car from Carbed to EFI and a ECU (Microtech). The car honestly has never been tuned right. It has gone to the best known tuners around, yet still they could never get it right on. I had a shop build this motor for me, but have never known exactly what was done to it, as this shop was very unreliable. Since so many problems with tuning issues we have come to the conclusion that possibly the motor isnt as strong as thought, nor the port as big as we thought. So, as Im writing this the motor is being opened up to see whats up, and is getting the best of the best put into it, along with another port job. (bigger) When done the car will be doing 250hp.

As far as the Camden Supercharger, yes I have a brand new 7 in blower on it, that Camden had re-designed making new modifications. My boost was 5lbs, but now Im running 10lbs without changing any pulley. I stand behind Camden and hope eventually I am able to show everyone that it is an awesome product. I love the low end tourqe.

I will do an update when things are done....

have you done any drivetrain mods to handle the extra torque? Torque breaks ****, and you are probably around double stock tq.

You're saying that's a good thing, right ? 'cause if the lioness ( female ) doesn't get the gazelle from an element of surprise and initial speed within the first several seconds, the gazelle runs off and the lion goes hungry. Yeah, I watched that on Animal Planet...

I take it you meant strong and overpowering.

CODE BLUE 2

Yep, I had Dave Atkins and Mikey do a rebuild on my tranny with strong parts, and my rear end is also not stock.

On Camden's site they have 5 and 7inch s/c along with 9 and 12 s/c. Everybody is doing the 5 and 7 inch but I plan to do 9 inch. The only thing I am worried about is building the intake to put on the S/C. But I will control it with the Haltech E6X (not the Apexi S-AFC that I originally talked about getting).

omigulay

how can u put the 5inch one on? i dont think they make 5" for rx7...

also the 7" one, can i use it on 12A or 13B?

go to the website... they answer your questions there.. you can use it on both the 12a and the 13b...

damn already got the turbo...from the sounds of things I should have gone SC!!

I prefer SC to turbo because you get such an instantaneous kick of torque in the low end, and you don't have to over-rev. And I used to put the SC in MGs and Sprites (and brit metallurgy is the worst) and didn't have any problems with busted parts, though I did a valve job every year, but I could rip that BMC head off in 45 minutes.

I think manufacturers made turbos popular because they're cheap and easy to bolton and the peak HP made it look faster than it is.

Well, lets not forget that a properly sized turbo will give you a pretty good power curve at whatever RPM range you want (hell, most of the dyno comparisons between the camden vs any turbo (even stock), show that a turbo puts out more torque from 2k rpm up, and who here really drives/launches under 2k?). You want a decent charger setup, get a twin screw. Roots blowers aren't very good on a rotary. Check out pianoprodigy's post in the 2nd gen section.

rotaryxperamental

If you're auto-Xing there'd be times that you're under 2k. Just a thought.

I've noticed that these little cars need wound up before they GO. was playing yesterday, I found that they lag a little down low (never really noticed it). but when you wind up, it kinda plants you in the seat, kinda cool.

I'm also planning a SC upgrade as soon as I get the engine out.

this is some really good info.

d. quinones

Guys, tks. for sharing on the information, especially
codeblue 2. I'm planning on doing the camden setup
with my webber carb on my toy.

Something to definately look at when I get done with Grad School and need to start my next 'project'.

Don't tell my wife, she thinks this car is just a disposable 'driver'.

I did too when I first bought it.

Nice looking car!

No one is addressing the downside here. The heat sucks on the Camdens. In the upper NorthWest, it may not get as hot as it does here in Alabama, but I loved the performance of my Camden, but the heat was insane trying to control it during the summer months. I always wanted one, then I got one. Now, I will probably never have another one. It's very unique, but I would rather go turbo.

"No one is addressing the downside here. The heat sucks on the Camdens. "

Im in Austin and it gets crazy hot here too. Is it the extra draw on the engine that causes your car to run hotter? What is your cooling system like (original, OEM new, aftermarket?) Im interested in supercharging my 85 SE but at $3500+ it may be a while!

I like the idea of an SC setup. Modest to medium boost in power, zero lag, less wear on the engine seem to be the pros and my goal is a responsive, fun car more in the autoX fashion I guess, not to be Dyno king or anything. But running the SC guide off Camden's site I got this

1979 - 1985 Fuel Injected Supercharger Kit includes:

Seven Inch Supercharger Kit $2395.00
Microtech MTX-8 $999.99
Microtech Handset $150.00
Bosch Coils $200.00
TWM Throttle Body $350.00
TPS & Plug-In $109.95
Throttle Body Extensions $70.95
Throttle Body Air Horns $110.00
Injectors (4) $400.00
Top Injector Seats $10.00
Bottom Injector Seats $12.00
Tsunami Aeromotive Fuel Pump $292.99
Aeromotive Pressure Regulator $137.73

Total $5238.61

Not sure why 4 injectors are listed unless they are assuming an engine swap or drilling in another 2? Camden does a Turbo install cost comparison there as well but its not apples to apples as they include a complete drive train swap out in the Turbo costs as well. I would guess at that HP you would want to do that with either setup.

Seems like a pretty high cost per psi? If you were shooting for 250-300HP wouldn't it be significantly cheaper to go the Turbo route and the Turbo be small enough at that HP to perform with relatively small lag at low rpm? I guess if your talking a difference of $1000 or less it comes down to preference, but from what I have read on this site, couldn't you do a solid turbo implementation for less than half that?

Anyone do a Turbo build up on an SE with 250-300HP as a goal have cost numbers?

I don't know **** about this btw, all I have is what I have gleaned from reading posts on this site, thats why I am asking. It's something I would like to do sometime soon one way or the other, though I would likely pay someone who knows what they are doing to install...

And that number does'nt include lots of things you would want to do like a complete engine rebuild, new fuel pump, street port, etc if your going to rip it all down anyway and put a brandy new boost component in. Seems like to do it right your looking at 8-9k plus aditional labor if someone else does the install?

Thoughts? Am I looking at this wrong?

From reading around, I believe it would be possible using the 2 injectors from an 85GSL-SE. The stock injectors are 720 but you would not be getting all of the power possible. The price of 400 dollars is bogus, you could go to a junkyard pull two injectors and get all of them cleaned and tested for under 200 dollars(high rough est.)

I agree, but I would think that the SC would be more reliable and alot easier to install. Not so many custom jobs and weldings. If you have a GSL-SE anyways.
It was included, Tsunami Aeromotive Fuel Pump $292.99
I wonder if you could find a cheaper product that had the same pressure and quality. Im sure you could.

I think these answers are right, anyone please correct me if I am wrong.

But I have a question, why bosch coils? Arent they more for Euro cars? I know their spark plugs and things dont do much for our cars, so would the coils?

blown 83

Compressed air = more heat. More heat + south Alabama summer temps (or Austin, TX in your case) = higher temp readings than I like to see on a rotary. All of my cooling system was brand new at the time of the Camden. New '81-83 style radiator, new oil cooler (FMOC) & lines, new hoses, new water pump, and gutted t-stat. Not to mention a new engine also. For $3500, I would suggest turbo. I know the Camden is more unique, but you can build a more powerful turbo setup, for less $$$, than what Atkins sells the Camdens for. Just my $.02.

GAWD DAMN thos are too effin expensive for me.

680RWHP12A

thats cause they dont have a turbo

atkins sells a good product....
