Rensis in a FD?
#51
I don't like the idea of increasing displacement (increasing rotor size). One of my favorite attributes onthe 8 is the high rpm capabilities. And with bigger heavier rotors the rpm will be affected (anyone know by how much?). I like the idea of a 3rd rotor better. Hopefully the next 7 will be a 3 rotor monster!

Why waste your money ???
With primitive technology !

What ?
Power to weight ratio (power:weight) is a fraction for 99% of all applications. It's the power divided by the weight of the vehicle. This fraction approaches (1) with increasing power. The higher the fraction, theoretically, the faster the vehicle.
It is not weight:power. From your analysis the rotary wins hands down, but of course I know better.

However, this isn't a particularly meaningful figure to most people, and you won't usually see horsepower to weight expressed that way in print. Instead, the weight of the vehicle divided by horsepower results in a true ratio: 2,500 / 650 = 3.85:1 (note the n:1 notation). This calculation results in something that most people can easily comprehend... the number of pounds of vehicle per each horsepower of output. Either way, though, the outcome is the same...
Go ahead and check my math if you want...
2,000 rpm - 0.02 vs. 0.06
2,500 rpm - 0.03 vs. 0.08
3,000 rpm - 0.04 vs. 0.09
3,500 rpm - 0.06 vs. 0.12
4,000 rpm - 0.07 vs. 0.15
4,500 rpm - 0.09 vs. 0.17
5,000 rpm - 0.13 vs. 0.20
5,500 rpm - 0.17 vs. 0.22
6,000 rpm - 0.20 vs. 0.23
6,500 rpm - 0.23 vs. 0.24
7,000 rpm - 0.24 vs. 0.24
7,500 rpm - 0.24 vs. 0.24
8,000 rpm - 0.24 vs. 0.23

I totally agree with Jim. If the FD had a V8, I wouldn't think of selling it.
However I don't have unlimited funds to do a proper V8 conversion. Actually, I'd be happy if it was a 20B. Why would Ispend that kind of money and then have to say Doh! I could've had a V8!
Yes, you can do a cheapo V8 swap for probably 10k, but you get just a stock used Vette engine, you really won't see an improvement in 1/4 mile times, and you have an old used engine that may or may not last awhile. So, I'm stuck trying to give the FD more low RPM Oomph!
This is what I been saying for awhile, the FD is just no fun below 4k RPM!
I don't hear many people on here taking part in the Great American Stop Light drags. If you hear about KILLS and an FD is the winner, it is at higher speeds, normally on the Highway.
I prefer the quick off the line kill a Torquey V8 provides. With my other cars the races were normally over by the time I hit 60Mph, because the other car was far behind.
Reving an engine to 4 or 6k RPM to Launch, while trying to avoid wheel hop, break an axle, etc.. Just isn't as fun as the 2000 RPM Torque a V8 provides.

IMHO !!!!!!
A V8 is a waste of money.
I mean Jimlab car is really nice with a nice clean install etc etc.
But how much did it cost you ?
How much did it cost you to get the 50/50 weight back to how it was ?
How fast is it 1/4 mile and top speed ?
And how much power does it produce ?
Also what is the final curb weight ?
Have you lightenend it at all and if so what ?
I don't have a problem with V8's I just think I can make make a better car with a RE.
Also a RX-7 isn't a RX-7 without a rotary.
My 0.02c worth

I'd guess more than a lot of people make in a year!

Actually, the engine will be lighter than the FD engine since he won't have the Turbos, IC, smog pump, etc... Again, this is where I don't believe I can afford to go. Just a Crate motor from JEGS, etc.. Maybe, but not all the Star Wars goodies he put into his engine.
How fast is it 1/4 mile and top speed ?
Unknown at this time, I believe he calculated it to be in the 11's though. I'm sure Jim will chime in here.
And how much power does it produce ?
Nearly 650Hp in current trim.
Also what is the final curb weight ?

I don't know the complete answer, but yes he has.

In my final words, in some points I agree with you. Unless things change, I will be modding the Rotary, not doing a V8 swap. Not necessarily because it is better, but I can get more bang for the Buck at this time. Again that may change. Once a reliable company (not Granny's) starts making parts that actually fit and maybe even a company will come out with a wiring harness that just plugs into the FD's wiring. If all of that happens, then I'd be doing a V8!
