SS124A

Trust me, I can understand why you are pulling the BS flag. This 12A is still in break-in. once it is at its full break-in time/mileage.... it will be going to the dyno for tuning with AFR...

As of now I am only running 10deg of total advance... (will go somewhere between 24-27) running through Dual MSD's (I am on stock 1983 Ignition now) and then I can re-jet the Weber.

IN a straight line it will accelerate with circa 1999 Model Camaro SS's When you do the math for my power to weight, based on their power to weight I should be in the range I claimed.

as far as idle goes... Don't take this wrong... (I don't like starting **** flinging contests... and I am not... if you want to call me later and discuss how and why I would be more than happy to educate anyone on the nuances of Rotary engine porting.) I can name off atleast 5 forum member who are local to me who have seen my car, and its idle.... and can attest to its accelerating ability.

BUT... how many engines have you ported? Are you familiar with Laminar Flow? have you ever calculated laminar flow through a rotary engine port based on what you plan to grind it to? Flow through our engine comes in layers if you really take time and port.... you can get much better fuel economy (the TII I just finished is getting around 22 average) and much smoother idle, powerband, etc etc.

I have been on this board for about 6 years... through server crashes etc etc. I don't need to prove anything... IF you come to Rotary Revolution next year.. I guess I can show you anything you want (down the strip and around the road-course too). I'll likely have a couple of my engines on display there anyway.

for future reference... you should have spent alot more time with the primaries, beside just cleaning them up... and you can go alot larger with the secondaries with out any low rpm adverse effects.

the exhaust ports should apear to be chrome...

Well, if you have spent the time to create your motor to get great gas mileage and idle at such a low, smooth rpm, more power to you, brother. I just never heard of such an idle level like that on an RX-7 before; so, I decided to inquire about it. I didn't mean to come off as if I was calling you a liar; it's more along the lines of "is that a typo/how the hell did you do that?" Anything's possible, I know that, and I really would love to see your car. 225rwhp just seemed to be kind of out there for a "streetported" 12A, though; so, I posed the question. Thanks for answering. Maybe you can build my next motor? Heh.

I have an Ad in the upcoming RX-tuner.

Just look for the ad of with the white RX-3 in it. there is also a picture of one of the actual ports in this 12A... (my partner just happened to be taking alot of pictures during that build.)

Bear in mind... I said my 12A was "street-ported" it is more like what the aussies call an extend port..

check out the picture.

the housing is from an engine previous ported by an idiot.... the inner scribe marks illustrate the RB Street-port... the outer one is what I used in the 12A.. you'll note that it has quite a bit more intake duration than the one RB provides.


Back to the subject..
I am still all for a good 12A..... Simple engine change, no big surprizes.. you will not need to learn all the little things needed to convert to say a S5 13B... although it would be a good swap too.

Hehehe, Thanks for the tip Gumby13B and Thanks Directfreak that site was helpful alot.

Your reputation is not being question here. But making such big claims on an untested set up is missleading. Estimated Horsepower. Theres the key.
Oh, and Iam an Aussie and I have an Extended port. Further, power to weight has no place in actual horsepower calculations.
