I dynoed shortly after putting the DE-K in and got some very disappointing results (158hp/174tq Heres the thread http://forums.maxima.org/showthread.php?t=436002)

Since then, I made a custom 2.5" exhaust (no cats), UDP, TS ECU w/ stock rev limit and tuned to 13.8ish w/ S-AFC.


This is with SAE correction, No correction was at 197tq/hp.

Heres a vid...

I can probably pull more out of it by removing the butterfly valves in the lower intake manifold, extended rev-limit and pathfinder TB. Im not going to do any more N/A dynos, this was just to get a baseline before I go turbo.

 

Sweet AF...Why did you stop the fun early(6350)?

 

he prob coulda squeezed a few more hp if he revved to 6550...which is the stock limiter on the 4th gen...

what octane gasoline are you running? 13.8 is damn hot inside the combustion chambers at WOT

 

His sig points to N2O, so he MIGHT be using colder plugs

 

I thought colder plugs hurt na performance....and hotter plugs help na performance?

 

Point was that his 13.8 is safer with a cold plug vs a hot or stock plug.

 

It is on stock copper plugs, I think that a 13.8 air-fuel ratio is at the limit but is still safe. I tuned the air-fuel on the street with a gen1 S-AFC and a PLX M-300 wideband O2 and didnt bother changing it on the dyno.

Didnt really notice that the revs stop at 6350. I did take it to redline and bounced the limiter on one run and they all stop at 6350. Maybe it has something to do with the automatic ecu? Im happy enough with these numbers so Im not going to bother trying to do more N/A.

 

Looks nice, do you have a y-pipe or just the catback?What am I looking at if I swap in DE-K with y-pipe and 2.5" catback but no headers?

 

Cars and dynos vary.. so ...

Try it out and see what you get.....

 

What's your intake setup. I was bouncing off at 6,050 rpm and changed my stock to a stillen pop charger and now it bounces exactly at 6500 rpm.

 

The rev limiter has nothing to do with the intake...

 

Yeah .........
