What are the maximum RPM that can support the Rev-up engine without modifying rods or anything else, up to 8K, 8,5K????

Where should be the problem rising the limit? at the valve springs? rods? ...?

 

Power dies down in the rev-up around 6900...what's the point of raising the rev limiter if you don't mod anything else?

 

cuz it feels nice to rev high?
s2000 style

 

 

Performance nissan raised one to 7800 and they said that power falls at around 7600.

 

Even if the power falls off at a X RPM you can benifit from increased redline by supporting mods IE 3.9 FD, Cams ect, and MAINLY being able to hold onto gears longer in curves for road racing or avoid a shift for 1/4 mi.

 

What the Bingo said is true.
Plus if you rev past the max rpm, you may still have good torque. Then when you shift up you're higher in the powerband of the next gear.

 

Actually the stock Rev-Up engine stops making power at like 6400 rpm. And if you want to extend the redline without doing anything big like valve springs or connectin rods... you can get an ECU reflash and they rev up to 7500rpm but I don't know if Technosquare has a program available yet.

 

Here is my stock dyno along with my sig dyno for comparison sake. The power starts to slightly fall off, but really is not that bad.

Green = stock
Red = plenum
Blue = sig

 

Well, I wanted to know where is the "physical" limit of this engine. Of course the only sense of raising the rev limit is if you have installed cams... but I wanted to know, in that case, what should be the rev limit if you don't change springs and rods

 

My rev limiter is set at 7500RPM, I havent dynoed the car yet but will soon. I can still break loose the tires at WOT from 1st to 2nd.
