Wheres the top end?
Im looking at alot of the times for the 4th gen maxima 5 speed, and alot of them have awsome 60 foot times, and very low 1/8 times, but finished the 1/4 kind week...
Why are our cars so week top end, even with mods like Cat back exhuast, and Y pipe...

I'd say do it yourself..and you can see the prices for the mevi's in the group deal area. Imagine...30extra wheel hp at redline pull baby pull.

I'm curious as to how you are deducing from the 1/4 mile time that the maxima has weak topend? 1/4-1/8 differential? Before MEVI I gained about 20mph in the last 1/8th, now I gain about 21mph. 19-21mph is typical for a street driven car.
Also, why such negativity about the VI? You complained about not having top end but then the one real solution to get yourself more topend you scoff at...? Strange to me.

slicks, MEVI, ypipe, intake, weigh reduction. If he had a jwt ecu he could possible hit 13.7-13.8s @ 99-100mph.

and how are you comparing to say maxima's have bad high end?
i think the high end is pretty good. i was trapping an average of 94mph with a jwt filter only.
and that was with crappy launches of 2.4's

I believe that at the track it does hamper you a bit. In the low-mid range I lost power, at 3400 I went from 185ft-lb to 168ft-lb, and at 4800rpm I went from 189ft-lb to 172ft-lb. However, even in the 1/8th mile, I am now trapping higher than ever. Over 77mph consistently, almost 78 on occasion. So even with the torque loss, in the first 9 seconds of the race, I'm already going faster than I was before. After that, things just get better and better. It's effect on top speed is phenomenal. Prior to the MEVI I could get to 6000rpm (indicated) in 5th gear, now I can get to an indicated 6500rpm in 5th, the high end charge this mod gives the car is phenomenal. If you want more top end this is the mod to get (for the price).

From my sig...
The USIM will give you better around-town peppiness, and give you better off-the-line performance. But the USIM makes the VQ fall flat on its face at the top-end, so you're very limited in highway pulling power.
The MEVI is the exact opposite. Superior top-end, but not as much low/mid-range. But highway pulling power is increased phenomenally. You have to shift the USIM VQ into 5th at around 5600rpm if you want to keep moving. But with the MEVI you can hold 4th all the way to the limiter, and then hit the limiter again in 5th if you have enough road and pull a significant amount on a USIM Maxima.

What about products like the ECU upgrade, do thoes giver gains threw the whole power band? anyone have dynos on that?
The MEVI intake is nice, i just hate losing some for gaining some...

well if thats the case, when you're racing, you shouldn't be in low-end rpm range at all.
other than the launch, you should be above 4000rpm give or take.
so the MEVI would be very beneficial, since low end isn't really too much of a factor when racing.
