Calling Dyno/Mod Experts
People with FIRST HAND experience only please!
What type of gains should I expect at the wheels with:
?
JWT Popcharger
Crawford Cats
Lightened Flywheel
UR Crank Pulley
I dont want to search I just want up to date BRUTAL honesty
Also how much should I expect these mods to impact my 1/4 mile times if any. Ive been resisting the NA mod bug for almost a year now but I have a feeling its about to hit bad!

The math says about 20+ hp.
Reality says about 10+ maybe 12+ hp.
Not much more than .7 sec in the 1/4 mile. Depends on the driver also.
Best bet is to get it dynoed for the truth.
That damn bug bite hurts but you have to scratch it.

area under the power band should increase a little bite, depends on how light your flywheel is.

With those mods you are looking at around 10-15HP thats assuming that stock dyno number is 235 to the wheels. Here is my dyno with all the mods in my sig. I made around 30HP extra.
Different mods will very in results with HP and TQ. If i would of went with crawford headers i think i would of made alittle more. NOt sure how much.
You want to add a ECU reflash in there to take advantage of those mods. As you see from my dyno i made 10HP and 9TQ with the addition of the ECU reflash.
SO all the mods in my sig only netted me 20HP
OH well

Aceman, did you modify your AEM intake? If not that could be hurting you as the standard AEM setup has been shown to be worthless and actually have a negative affect as you add more mods.
As for the original post, I would also say 10-15HP and maybe 0.2-0.3 sec off the 1/4 mile mainly because of the flywheel. I would recommend a plenum over the UR crank pulley especially since you want to go with a lighter flywheel. The plenum is something everyone should have to allow more even air/fuel to all the cylinders. It will also help quite a bit in the upper rpms and give your car a better overall exhaust tone. I have even heard that Nissan is interested is the Crawford design since the stock plenum does restrict air flow to the front cylinders.

the flywheel mostly improves 0-60 times correct?
How many hours of labor does it take to install one of those bad boys?
IS it a warranty voider?

0-60 times? That depends on the other mods, the driver and the weight that you reduced on the car itself.
Cool?!

thanks..I guess I was just looking for #s and reactions from ppl who have the setup.
I dont want to do it unless I notice a BIG change.

As you see from my sig i ran a 13.6 with Flywheel and AEM intake only. I have a Base 350z, so only one tire spins
so i think thats a pretty good difference.As far as price, i paid 420 for the flywheel and around 350 for install. I like haveing the flywheel, took some getting use to at first. But its just like when you buy a new car, takes awhile to get use to it aswell

Did they do the inductive rpm pickup right on your runs? The graph looks like rpm pickup was setup wrong...

Yeah, i turned my AEM CAI into a short version. I just removed the bottom pipe, it looks like the JWT version now.
