just curious....she seems to really perform well there.....

 

umm... yes... why even ask.. .you redline at 7k. Hell i've got 171,000 miles on my origional motor and i take it to 7k daily.

 

come on buddy!, you have 'Posts: 249' ... what the heck youve been writing about?

 

Redline a day keeps the carbon away i actually gained compression by beating the snot out of my engine since before i got it the lady never took it past 1/4 throttle or 3500 RPM. (now in no way shape or form and i suggesting you beat the crap out of your engine, just that redlining it every once in a while isn't a bad idea )

 

If you don't regularly feel like taking it past 6500 RPM or so, check your aux ports. :-)

If they're working properly (mine are working properly now), the engine pulls hard up through 7000-7500 RPM.

another thing to check is the double throttle assembly, they can stick shut!

 

hmmm, so redlining it for a fraction of a second is a good thing. How will you know when you're getting rid of carbon?

 

take it all the way to 8500 !!!

well if its all stock it should be pulling until 7000 at least

 

Yes, its a rotary not a piston engine.
Rotary go hmmmmmm

 

Don't worry about it, its magic and beyond your comprehension level.

 

Ohhhh, buddy has jokes. Work on them......

 

S4s have a fuel cut at 8k, and "official redline" at 7k.

I shift around 7500.

id say up to 5500 is safe for normal streetdriving but you dont want to stay up high for long , you usualy want to switch gears instead of holding at high rpms but to floor it and rev it up to like 7-7500 k is fine so long as youre not doing it constantlyand u shift right away instead of porking it in every gear until it hits the governor (beating on the motor)

 

actually at 7800 but who's being specific




If your driving the car hard i.e. at the track/autox/on an awsome twisty country road, you'll really enjoy the car in the higher RPM's i usually take it till about 7700 before i **** but that's going all out plus with intake and exhaust it seems to just keep pulling. mind you my motor only has 10,000 so i wasn't too afraid of it letting go anytime soon.

 

Same here, when i bought my 90 GXL the aux ports werent working; they started working again on their own just by regularly taking it to redline.

 

actually you are wrong. both of you. The fuel cut on an s4 is 8500 rpm. This is dyno proven by my self and others. I see the fuel cut all the time. Rev the **** out of her! i've never heard of anyone saying there engine blew due to revving too high . ? My engines surly don't complain

 

It is okay, but you probably know that now because of all the other post previous to mine, haha.

 

my s4 turbo II had a fuel cut at like 7,800 rpms (i'm not saying that all s4's do) when it was stock, so Dom C you're the one that is wrong.

 

ok i guess not all s4's, i wasn't think ing of turbo's. . My car is N/A. The ecu's are different. Also the stock tack is not accurate at those rpms. While at the dyno i watch the tach in the car and it read 7800 rpm, but the dyno tach read 8500, the stock tach just isn't acurate. I am not wrong on this one.

I'll even go further & say a sustained 6K is fine as I;ve done this going over Carson pass up to Lake Tahoe on hwy 88. The verts are damn near bullet proof. I now have 176k & still going strong Still, I can't wait to put in two oil coolers when it come time to do an engine rebuild. Insurance you know.

 

I've only had mine for a month, and 7k ain't a thing for mine (Mazda rebuild sub 4,000 miles right now). The buzzer is there for a reason, just don't forget it. I'm not saying go ***** to the wall everytime. I only open it up, big boy style (7k shifts from 0-110ish), whenever there are no cars around. Don't worry dude, it'll take everything you throw at it, and then some.

 

Thats one hell of a pass, sadly I've only done it in my brothers 78' Westfalia (twinky van )

 

I know a guy who drives his rx7 at redline for kicks. He will be driving down the freeway at redline with the buzzer going. Hes been doing this like years and years and car is still perfect.

 

and how exactly is the vert engine different from any other NA engine? A regular NA rx7 would probably he more reliable than a vert because it doesnt have as much weight.

 

I was wondering that myself, and that is also a really good point. I wonder...? Hmm... Perhaps we should find out the sorta MPG guys in verts get, and take it from there.
