I think the cool thing is that you can do the full exhaust, bigger injectors, intake, tuning, AND add a supercharger.

 

I found the numbers on Camden's old site that I mentioned by using archive.org.

Ported and Polished Four Port 13B with Seven Inch Supercharger

Ok you guys make some good points and I was wrong about the fuel injectors but at some point if this thing makes enough power you are going to want to also do a drivetrain swap as well, and I know there are others that also disagree. I am very curious to see whatthis thng would do with a bigger pulley, half bridge or a streetport, standalone and the like, then you are talking.

 

Yes, this is true; however, what results are to be expected with such modifications?

Honestly, no one is completely stock especially those who are seriously considering a supercharger for an NA Rx-7. I and many of you are most interested in knowing the realistic potential of this setup.

 

I think I am in the market for this.....im not sure though, I could make my own kit, but I would rather support a company that makes kits for our cars

 

i think with a full NA setup ( lightened pulleys, removed ac, street port, t2 fuel pump full 3in exaust stand alone unit bigger injectors, grounding wires, spark plug wires, lightwheight flywheel etc.) i think 250-300 hp could be might be a possibility at the wheels 250 bein pretty conservative. though gettin too 300 u might want t2 rotors too lower the compression a bit

 

FUll N/A set-up you mention would not get you anywhere close to 300 Hp unless you go radical on the port job, I mean a P-port motor. The set-up you mention will get 200 FWHP tops with a street port.
And if you stay N/a why would you go for lower compression rotors and loose power???

 

these #s were taken @ the flywheel with a carb NOT RWHP.

I might want to buy this supercharrger kit, Is the redline still 8k after putting the SC on, how much boost does it make?

 

I'll post this again so you won't miss it...

Dan and others who know...

I'm very confused about this kit. I understand that 176 rwhp on a forced induction car will be much faster than an 176 rwhp on an NA car, but I was under the impression that the carbed kits made much more power (the numbers I'm talking about from Camden's site are no longer available). I guess my questions in order are:

1. What series motor was used for the testing?

2. What kind of porting did the motor have?

3. What other modifications did the car have?

4. What were the rwhp and tq numbers? (Dyno chart would be extremely helpful)

5. What potential does this system have? (i.e. currently running 6 psi but could run 12 psi with more fuel)

I know that Camden's site said something about "260 horses" a while back. I do not know if this was a flywheel hp or rwhp number, but nothing in this thread references anything close to that number.

Thanks in advance for your responses as my 90 Vert eagerly awaits forced induction...

 

does anyone know where i can get a cheaper kit or instructions to build my own?

 

The motor was street ported 6 port s4 a full RB exhaust system the rest of the car was ALL stock.
The dyno chart I will find it here @ the shop and post it up for you all to see.
the system is running on 6psi right now you can go to 11 psi before we have to make more pulles .

All of the #s that you saw on the web site were @ the flywheel and NOT RWHP.

I hope that this answers your questions if you have any more please just ask.

Later

okay so I went a bit overbboard with the 250 whp but I still think the 230 is reachable. People have been hitting 160 whp NA with stock ports and close too 200 with street ports so (one note these are virtually maxed NA motors) so 230 whp should be reachable. The lower compression t2 rotors were for when u put the sc on there so u could run a bigger pulley ie. more boost for the sc. so i think 230 whp is possible but heck we will have too wait and see see.

 

Dan,

Thanks for the response. Please post that dyno chart when you get time.

Alan

 

Is the red line still at 8k?

 

Dan: would you please explain the upgraded injectors and fuel pump you would suggest for increased horespower vs the stock injectors. What would be required and what numbers would be a fair expectation for such upgrades. Thanks and great job

hi people im new here to this forum , but ive been following the sc kit for some time, i bought the kit and its being put in as we speak, i and my mechanics have ran into some probs , but there small. one question i have for u dan is , i live in cal and i know the emmissions crap out here sucks , but what about the idle have u guys worked out the bugs with having to idle the car at 1500 to 1800 rpms , i was talking with one of the tecks that u have and they said thats what its going to have to idle at , at all times. from what atkins tells me im the first in the state to have the supercharger. will keep ta posted, rx790vert

 

i was told from atkins to stick with the 450 primes for idle and get the 650 secondarys, with a wabro fuel pump, from the numbers that they have out plus what i have , i got 305 to the fly, 240 to the wheels , now mind u thats based on what i have done to my car so far, but ill know more when i get it dynoed.

 

I'd love to see this kit with an optional Whipple 2300AX.

Congrats on the design, a pretty ingenious little setup, and not a bad price at all. If I still had the rotary engine in my 7 I'd be all over it.

Edited for spelling like the high school kids on this forum...

 

Haha, don't worry, I'm working on the Whipple 2300 As for those 240rwhp and 300fwhp, where the hell did those numbers come from if you said you haven't been to a dyno yet? Sounds a bit much on a charger running no more than 10psi.

 

Sounds like a time bomb..

 

What's a time bomb? Kind of a useless statement if you don't mention what or why.

 

I didnt read the entire thread, but what's going to control the larger injectors and fuel pump? From someones post previously, 305 FHP would just be itching to be blown up on a NA 7.. Hence a time bomb. It may run fine for a few weeks or months, but it will blow up, and the cost of a S/C kit could be put towards a nice TII..

 

SX fpr & s-afc, is the general idea. What makes you think 300hp on an 6port is so unreliable? However, I do seriously doubt that this kits going to get 300fwhp, but just curious as to why you think that.
