I have had 5 FC's (NA) (1986-1988) of all types since they were new. They go 128-130 MPH TOPS! Any faster than that then they are modded or the speedo is wrong. I can't tell you what a 1989-1991 NA will do because I have no experience driving one that fast.

My boy Hutch's modded NA, we've gotten that lil hoe to a lil past 140. 143 I believe is the exact. But that was it. It wouldnt push anymore than that. topped out.

We did it. Explain that one. And speedo was not broke. It surprised me too but the car WAS pegged.
His wasnt ported either. It had:
No emissions
weight reductions
intake
exhaust
16" rims which might have helped.
removed 5th/6th ports

I have gone 150 mph in my 87 fc N/a I had Full exhaust from racing beat, HKS Intake, and A center force dual friction clucth. It takes a little while of being on it though. I could easly get to 135-140 mph.

When I first got my car I topped out at 128mph with stock everything, now I get her up to 145mph(8k in 4th) at least 2 times a week. When I topped her out I go to 8,600rpm in 4th (150mph) then shift into 5th and if I hold it to the floor I can keep it going 150mph for as long as I want.

the fastest i could get my car was 125, now i can't get it to go past 120. Something's up but i'm not sure what it is...i think it's the lack of cold air and the hotter weather.

This topic of this thread shouldn't be "top speed"; it should "highest speedo reading". If you guys think the speedo isn't reading high at those speeds, you're kidding yourself.
Some claims here simply defy the laws of physics. Power required increases to the third power of speed, so to increase your top speed from 130mph to 140mph (~8%) you need 25% more power, and you need to be making it 8% higher in the rev range. Assuming a stock 160hp S5 can reach 130mph, it'll need 200hp to get to 140mph. To get to 150mph you'd need 245hp. See how some claims start to sound a bit unlikely?

Thats assuming everything is flat, there is no wind, the air temp is at what? WAY to many things go into how fast your car can go. Not just hp. (not bashing just making another pointer)
Math isnt always right. (yeah I know it sounds dumb)

This place should be called the RX-7 MIS-information forum.
Let me go along with the flow of insanity here.....
OK.... My modded FC NA with the usual mods... Let me pick a number....????..... It goes.... 170+ in 3rd gear uphill into the wind.... I do it several times weekly...
stock FC modded... TOPS=135 MPH AT BEST!!!!!
