N/A im at 4.89 or around 4.9 volts on the MAF. Will N20 make me PEG the MAF? The tip for the N20 is after the MAF.....Kinda thiking of going back to the stock MAF

While I don't know anything about juice

I do got a bit of horse sense
so
Lets think out loud about this concern

With only the help of mother nature forcing air in the holes .........
You are almost pegging the meter

When you throw the juice switch ....
You make much more power ... Do you Not

That power is gonna draw more air past the meter ... Is it not

I'd say ... YES ... Juice is gonna push your meter over the top

I kinda new thought just wanted to make sure.....since it was forcing air after the MAF I wasn't sure how that would affect it

The nozzle for the nitrous doesn't put and more air in, just nitrous and fuel (if its a wet kit) The extra air the motor will suck in still comes through the MAF so yes you would peg it.

get a BA 2400 MAF and call it done for awhile

blksn955.o · May 21, 2007

hitting 4.9 alone you should get a bigger maf N/A.

To be safe I would say get a bigger maf no matter what. However, n2o does carry its own air supply and n2o kits add fuel outside of the maf commands really.

1. they tap into the vac. and jump the FP to 80psi or so (dry kits do this most commonly). The inj. size along with fuel pump size are the biggies

2. they tap into the fuel line and run a fuel jet that is meterd' to add the needed fuel for the n2o jet run. With this type of kit the fuel pump is the biggie.

I know with GM kits they on some kits spray threw the maf but there setup is diff. from ours and that is really not a good idea. So dont really take any tips that are more specific to the GM style setup unless they are known as an all around n2o guru.

The n2o "should" not have any affect on the maf but it sounds like you really need a bigger maf anyway so I wont be the one to say you DONT need a maf.

Can one make more hp without taking in more air

Thats just it your not really taking in more air...its just attached to something that has more by volume than reg. air.

Its kind of its own seperate system when sprayed after the maf. that is why the fuel adding is done by non-eec manipulating(sp?).

Your already (the way the kits work) adding more fuel to make up for the more air that is contained in the n2o. Not to mention the -125* phase change from a liquid state to a gas drops air inlet temps (why timing can be run fairly high for the amount of power added).

Now if you were to spray the n2o before the maf....I bet the maf would go NUTS. Also a wet kit would FUBAR that sucker with all the fuel passing threw it.

With his maf already at 4.9...GET a bigger maf. I could see a short spike when the nozzle first starts spraying if not for a possible quick pres. change in the intake track...fallowed by a sharp load spike. I woulnd really expect to see much of a airflow rise at the maf though.

makes sense... good info

final5-0 · May 21, 2007

OK Mr. G

I gotta change my position here
I gave some misinformation above

Greg got me to thinking a bit here
and
The out come of it is ... He is right & I am wrong

Since juice is all about adding more O2 directly to the hole

Your meter won't see an increase in airflow
however
Like Greg said above ... You are basically done with that meter

I still don't want anything to do with juice
even though
I now know more about it

Sorry to all for my contribution of confusion

Grady

blksn955.o · May 21, 2007

for all the contributing you do...I think its ok, since you more or less asked a question that is a good one anyway. It is kind of a working around things method of adding power...n2o is automotive crack though. You always want more.

I think you can ask all the noob questions you want as far as I care...like what tails should I get clear alteza's or 96+ tails

Actually I have a 90mmLAMF. This thread is worthless now. I set my A/F alot straighter, so theres no need for me to go back But thanks for the info I have a better understanding

Well ... You're not the only one who learned something new

I really gave that some thought
after
Greg provided his excellent info

To my way of thinking ......
The concept of making more power
without additional airflow
being passed throughout the entire motor

Well ... It just seems so bazaar & freaky strange
Its obvious ... I've never given it much thought
but
I did a good bit yesterday

I still came to the same final thought about juice

For each and every bottle I drained dry ........

Its cost could have been set aside for a part that would give me ...
More power ...... ANYTIME ...... I wanted it
with
NO reoccurring cost like Juice.

Nitrous is like a Credit Card. Poor man's supercharger on a payment plan. Rent to own power if you will. Payments are cheaper, results are great, but in the end you paid a lot and ended up owning not much.

But I see it as eating. You can go drop $25-$50 a plate for some fine dining... or you can drop $5 for a quick meal. The end result is still poop.

With that said, I'll use the bottle for a while longer.... when I get to where I feel I need MORE power, then a supercharger will come into the plan.

Grady, I was thinking a similar way to you. blksn955.o's explantion was awesome and I guess I should know a little more about a topic before i post I might try out nitrous down the line since my compression is a little too high to boost it.

I too would like to have built a turbo but 10.5:1-ish aint' gunna cut it.

I went with a bottle for the exact reason you dont like them. I can have a fairly mild combo that gets relative good mpg. When I want to/"need" to I have an extra 150-175hp at the flip of a switch.

It just puts you in a whole other league of car, and then you can just go back to "normal".

The refills kinda suck, but really I have not had one issue with being out of bottle. I dont go around just spraying for the hell of it though.

I am what one could call a "cheap" A$$, I pieced my kit together here and there and have less than $250 in it total. That and its been nice just leaving the bottle out of the trunk when I have been sorting out this thing...god only knows what kind of trouble some boost would have gotten me into.

Boost or bottle I like both, the only thing that gets to me is when dingle berries say its "cheating" . yep sure is thats why it outlawd' by NHRA and NMRA so unless your talking about KITCA- excuse me NASCAR or some other roundy round were they dont have boost either...
