I put this in last November. I have just been lazy about the pics.



Here is the ball of crap I dug out of the egr tube which connects the intake manifold to the exhaust manifold.




Checking the rpm switch for activation. Notice the red and green lights.



I decided that since the intake manifold would be off, NOW was the time to replace the valve cover gaskets and the spark plug o rings. They were not leaking, but I figured that with the manifold out of the way half the work was already going to done. Better than having to pull the whole intake manifold again if I get a leak latter on down the road.

 

Blowing weed smoke into the old intake manifold.



Pounding a new spark plug tube o ring into the valve cover.




I put the canister in my vise and used a screw driver and hammer to bust the rivet on the bracket so it could be removed.

 

This was the perfect spot for the vacuum canister. Once I put the engine cover on, it is completely hidden.



This is where I tapped the vacuum source. If you look carefully, you can see the t piece I used.

 

This was the perfect spot for the rpm switch. I zip tied to a couple of wiring harnesses so it could not move around.

 

Nice work Devin.

 

Freaking good job. I have the b&m sts too, how does the car feel hp wise?
at what rpm does the switch open?

 

Oh man past 5500 rpm the difference is night and day. No more of that power drop of around 5500 like with the US intake manifold. Now, the thing pulls hard straight to redline. The funny thing is that with the US manifold, I NEVER hit the rev limiter. I was always shifting before redline because of the profound power loss in the high rpm range. I mean you can just feel it! The first time I took the car out with the MEVI I hit the rev limiter cause it pulls that fast and hard right into the red zone! This is the best mod I have done for this car to date.

My guess is that because the summit rpm switch is made for bullsh!t domestic V8s you have to manipulate the switch slightly. My buddy Zack who had just intalled the MEVI on his maxima and told me how to set it right. The key is to set the switch to 3400 rpm shortly after hitting 5200 rpm, the solenoid activates and opens the butterfly valves. Its pretty cool to watch! This setting achieved the best results for Zack who played around with it while he had access to a dyno.




His dyno is pretty impressive. I plan to get a dyno myself here shortly.

 

picture makes me want to get a cover for my mevi to hide some of the wires, hoses, and canister. BTW i put my switch somewhat close to yours. I actually have mine under the cup holders i could take it out if i needed to. I have so many things running through that hole that use to be for the at lines.

 

I love that cover.

 

Saw that cover in your sig in another thread and was the WTF is that? This is my first 4th gen, so it didn't immediately jump out at me as weird. Well done w/ the MEVI.

 

can we expect an 00vi any time soon?

 

Don't count on it. I don't feel like drilling and tapping new holes in my lower plenum and I most certainly don't feel like grinding down my valve covers just for that meager power gain. I got better things to do like boost... which you can expect soon.

 

please tell me how you wired up your summit switch

 

Do you have an ECU upgrade? With a bumped RPM and Fuel ratio?

 

For the rpm signal I used the TAM screw on the back of the gauge cluster. I used a ground gromit thing on the screw. It will say "TAM" above the screw. Run this to the white wire on the summit rpm switch.

I used the cigarette lighter wire as a power source for both the switch and the solenoid (red summit wire). And I just used a nut/stud off the plate bolt around the shifter as a ground (black summit wire).

Then, run the yellow summit wire to the other wire on the solenoid.

The grey summit wire is unused.

Set the switch to 3400 rpm.

 

Nope. I don't really feel comfortable taking my car past 6500 rpm.

 

just to let you know there is no TAM screw on the back of 98 clusters. i had to splice into the tach signal wire from the ecu. When you get the sc in after 5000 pulls hard as crap and you will get to redline REAL quick. I'm going to try to get the eu soon and hopefully get a couple hundred more rpms to play with.

 

yeah i am trying to decide if i want to go with a vacuum canister for activating the MEVI when i get on. Or if i want to set up an electrical solenoid. So i don't take any vacuum away from my System. that way i can use minimum parts for activation and get a little better accuracy on when the runners open. If i do get the mevi i will definatly have to go find a 96 max manual ecu so i can stick that into my 99 max manual.

 

thanks , you wouldnt happen to have any pics of that part of the install would you?

 

With the raised Rev limiter why would you fell uncomfortable going past 6500rpm?
The whole ponit of the MEVI is to get that top end gain.
If you plan on going boost I can tell you now that you will want to go past that 6500rpm.
From 3500 to 7K the car will pull hard all the way up building more boost as it does.
At 7k I hit 10lbs of boost on a 3.0 pulley

 

My understanding is that you need both the solenoid and the vacuum canister. Zack342 had a 96 manual jwt ecu that he had in his 99 for sale. PM him ans see whats up.

 

I don't know. I even got a 96 manual ecu for the jwt extended redline and I don't doubt that the extra 500 rpm would be extremely beneficial. I just had second thoughts about if I really want to put my valve train through that extra stress. Maybe I'll throw one on after I boost.

 

Shouldn't it be more than 10lbs with a 3.00 pulley reving to 7k. with a 3.33 pulley + stock rev limit i'm hitting 8-9. 3.25 should already be up at 10lbs. It pulls pretty hard up top and that rev limit comes at you pretty quick. i'll admit i've hit the rev limit a couple of times

 

Im using a V1 blower. V1's see a bit less boost then the V2.
There is another SC max here localy and with his V2 using the 3.125 pulley he was hitting 10lbs.

 

Thats kinda how I felt to originally. thats why I only got the 7k rev limit. Now I wish I had gotten the 7200.
Like abci30 stated, under boost the rev limit comes very quick, it doesnt take longto hit 7k. I could see the 7200 limiter building another .5-1.0 more lbs of boost.

 

so you didnt use any kind of relay switch correct?

 

Nope, its not needed with the summit switch.

 

roger, thanks for the assist.
