RX7_Edgar with the 5th and 6th ports fixed you will feel the difference

Edit: ZeroStage: WOW, you definitely proved me wrong. What kind of compression does that engine put out? Any porting? Engine mods?
In my car I would top out 4th gear and as soon as I'd put it in 5th it would immediately start losing speed..

If your aux port actuators are frozen shut that means you are running on 4 ports instead of 6, this will cause a HUGE power loss.

By the way, when i change from 4th to 5th the car dies a lot but it doesn't loose speed.

And that video doesn't appear to show your RPM over 5800, so that $100 bet might still stand being that it'd be under it.
I don't have a clue about the compression of the engine.... At the time i made this movie the only mod the car had the exahust that didn't have any converters... all the rest was stock...

So you did the single most effective power increase modification for an N/A short of cracking the block and wonder why its faster than stock?

Sorry, but your speedometer is hardly accurate enough to accept as proof of anything save forward movement. Hell, for all we know, you're running 12" rear wheels.
Let's see a radar trap ticket.
IIRC, Mazda only claimed a top speed of 128 MPH and you know they did everything possible to get there.
Once you cross the 100 MPH barrier, aerodynamics starts to become the dominant factor...not horsepower, not fuel octane, not driver ability and the RX just doesn't have the body to reach 150 MPH without some serious modification.

My automatic fc hits 100 easy I haven't tried to top out after I replaced the stock exhaust and did some maint work on it but I was able to hit about 123 or so, in a automatic. So if you can't hit more then that with a manual, your cars got some issues
edit to the guy postin video topin out, thats dumb video taping while going so fast whenever I push past 100, I keep both hands on wheel -_-

I was cruising along on the Autbahn when I noticed I was doing 210-220 KPH, so I decided to give it some more and got to 240 KPH (150 MPH) fairly easy. I slowed down and set cruise control to 210 KPH. I was already driving for 9 hours, with a 2 hour break, so my right foot was getting numb.

My both ands were on the wheel... The cell phone was between my hand and the wheel... Wich is why I dindn't change any gears...
??? I dindn't really understand that.. I said he bet 100 that my car doesn't reach 150.. Well... It reaches 150 as you can see in the video... What has that to do with the rpm??
Well... The exahust might be the single most effective power increase modification but my exahust isn't that good tho...

The stock exhaust minus the original cats will net you a good 15 or more pretty easily.

About the exahust... Are you serious?? 15hp only by removing the cats?? I'm asking this because when i bought the car, the exahust was alreaddy like this so i don't know how it would run with the stock exahust...
Sorry for the off topic but if removing the cats give you about 15 how much do you gain with a full RB dual system?

Well... I really don't care... The car marks 240kmh / 150mph... I only tried it about 3 times and it reaches that value... If it has a big error... I really don't know... If I have time I'll compare it with a GPS but sinse I don't have one I'll need to ask some friend one...

Wow!
I finally got my FC to go past 120 today!
I just remembered that I was super low on oil because of my Rear main seal that needs to get replaced.
So I ended up adding 4 quarts of 20W50 oil and took the FC down a long 5-7mile road and she went past 120 in 4th gear and it still kept climbing.
I just finished buying the rear main seal for $12 from Mazda and will get it replaced Tomorrow. I guess if I'm going to have to drop the transmission, I might as well replace the Clutch with an OEM Mazda Clutch kit.
Was trying to look for a Exedy but they were all $300 and above.
It just kept making me think and think the whole why the FC wouldnt go past 120! after doing every single routine maintenance on that FC!! Now I am happy that I finally found that the oil was really really low.

I used to hit 120 coming home from tacobell at 3am. It was a 3/4 mile strait shot. I still don't quite know why i used to do that.
