hey guys just wanted to know if installing the block off will trigger a check engine light just purchased one and had the question. thanks

nelledge

iTrader: (6)

No sir. Installed my second one today. No engine light either time. Follow the instructions and you should be fine.

sweeet thank, is low end torque loss noticable, how about the top end torque is it noticible?

Acceleration becomes linear. I have a 6spd so low end isn't an issue for me at all. It probably fell off a little, but it will depend on your supporting mods. I feel that acceleration has increased above 4k by a noticeable amount. It just pulls and pulls up to redline. There are several threads on it. You'll be able to add your own relative comments when you install yours. Personally, I love the difference. Go for it!

I have an Auto and the low end torque loss is minimal, but I also have NWP spacers and 17* timing advance which compensates for any minor low end loss ... and yes the upper end torque is noticeable.

I have a 6 speed and I didn't really notice too much low end loss honestly, but the car kept pulling all the way to redline...really noticeable. You will not throw a code installing a BOP.

Sound great thanks for alao purchased a short ram intake from a fellow org member hopefully it turn into a great combination

Block off plate and the short ram ... you may also want to consider the 17* timing advance to compensate the low end not to mention a little improvement in the fuel economy.

Defenetly will take into consideration thanks for info

Me too waiting on mine, my other Max had Intake, LWP, Exhaust, and the BOP, but this one will be probably just a JWT popcharger and BOP till end of the month then add Full Cattman system...and no CEL ....

Sweet sweet also looking into some tires and lowering spring to slap on my g35 rays

Just make sure to keep the solenoid plugged in, and you won't throw a CEL. And obviously cap the vacuum lead.

You lose a little torque and you gain a little HP, resulting in a mind-trick in how it's perceived, making it feel like the gains are more than it really is. Still, the BOP is a fine little tweak if you've got supporting mods so that the low-end loss is negligible.

I prefer the linear behavior in the engine better than that turbo-like kick of the VIAS. Some people like it, some don't. It's a personal estimate, and entirely reversible.

Man, I hope somebody fixes the search feature sometime this year.

how much of a diff in fuel economy with the BOP, but without the 17* advance?

Scottwax

iTrader: (8)

Not one bit of change. You will have a drop-off initially because you are romping on it more to feel the better top end pull, but in normal driving there isn't any difference.

Ghost_54

iTrader: (13)

As Scott said no real change in fuel economy with just a block off plate, just that the engine will pull in a more linear fashion rather than that secondary pull you feel at around 3500 rpm with the VIAS in place.

Increasing the fuel economy comes from some secondary mods such as, short ram intake, NWP spacers, a 17* timing advance to name a few. When my car was completely stock I ram 10.3ltr/100km after the short ram intake and timing advance was done (and I stopped romping on the engine) my fuel economy settled in at 9.3ltr/100km. When I made a minor adjustment by replacing my muffler to a performance one and deleted my resonator in favor of a straight flow through pipe another minor adjustment in fuel usage went to 9.1ltr/100km, with the addition of a custom made block off plate, some new colder spark plugs and NWP spacers I am now at 8.7ltr/100km and one hell of alot of torque in the upper RPM range.

So it is a combination of mod's that gave the end current results, that and just the practical knowledge that the Max is a great cruising car on the HWY (I do about 75% of my driving on the HWY) and the car loves to cruise at 110kmph. Stop and go or short hops to the corner store absolutely kill ones fuel economy in these cars no matter what mod's you have done ... take it to the HWY and let the engine cruise!!!

just got mine today, 10 bux, lol how freaking cheap!

No spacers nor lightweight crank pulley... not sure you're going to like your new low end, hotshot.

But for $10, it's worth a shot.

Got mines yesterday, looks bad a$$, just one question it came with 3 bolts and a small black thing havent opened it but cheked the instruction but dint find anything refering to it.

Vacuum cap. Read the instructions. Aaron makes it simple for us. Very simple.

OMG, you are so nice, Cowboy. That post was positively begging to get slapped aside the head.

Actually, I'm trying to balance my abruptness with a little patience. I do not contest your assessment, however.

As mentioned, that is the black vacuum cap. It caps off your VIAS solenoid once the VIAS actuator and hose is removed.

It is outlined in Step #5 in the instructions you received with the kit.

For anybody else reading that is interested, here are the instructions in PDF format:

One question. Im also doing this mod on my 03 6mt. I dont drive the car anywhere past 3k rpms on reg driving, will I feel any loss of power during regular driving??

Rochester

iTrader: (3)

No, you'll be fine. Simply put, you're not driving the car hard enough for it to matter one way or the other. Which is actually not a bad thing, because each time you peg the throttle, you'll appreciate the difference between driving like Grandma and driving WOT. But that pretty much applies with or without the BOP.

Look, if you don't like it, then simply replace the VIAS valve.

svillegas2253

Thanks. Im pretty sure ill love it. As long as its the same at low rpms. Thing already pulls hard and all I have is an intake lol

You will get some sound if not small power gains. Enjoy!

Hi guys, read this thread, which might explain my 'issue'

I've got a 2000 Ti auto - 3~ weeks ago. The other day when I floored it at the lights it took off okay, however i kinda felt like some sort of cam timing was happening, as I felt a very slight then i felt more power.. kinda like say, NVCS on a Nissan skyline, where at the switchover(5000~) the VCT switches off which sometimes can be noticeable.

Dont get me wrong, it wasnt a misfire or anything, it just felt like NVCS was kicking in.

Does the 2000 maxima even have NVCS? or equivalent? (or is VIAS it)?

Maxima's have VIAS which switches around 4k RPM or so, I believe. I'm not sure anymore on the RPM cutover for I removed it last year and put in a blockoff plate, then bumped the timing 2* to compensate for the loss in low end torque.
