Judge,
I'm just going back through this, you've said you had a four fogger system but only used two of them and were providing a 165hp nitrous hit. So it is effectively from a 330hp NOS kit (each nozzle giving about 80 odd hp)?
The Holley is a 4 barrel, and I expect the manifold has a long runner for each port.... so with only two nozzles are you only injecting N2O into half of the runners? I am just trying to get this clear in my head.
So do you feel that a bigger shot works better than say double the number of nozzles at half the flow? So 2 nozzles flowing 165hp is better than 4 nozzles (one in each manifold runner) that are collectively flowing the same amount of nitrous?

Judge Ito

Hmm Buzz have I sparked your intrest in N20? I'm using a "Pro shot Fogger" this nitrous kit is adjustable from 150 to well above 500hp! on a 4 fogger set up. Right now Im using some 80hp jetting per fogger with a little on the lean side on the fuel pressure regulator adjustment. I'm using a Racing Beat intake manifold, yes the manifold im using has some long runners but I installed the foggers directly into the lower part of the manifold.(when I say lower I mean right in front of the port) I have tried a 4 fogger vs 2 fogger installation on the lower part of the manifolds, and I could tell you that 2 vs 4 foggers 2 was a simpler way of tunning and making more power in the location that I have the foggers. Buzz keep asking me questions before you know it Ill have switched over to some nice n20

Thanks Judge - what it would take to switch me on to running nitrous would be having a drag strip in the local area; (we got shafted out of our 1/8m by the Local Government, then it turns out the land we identified for a new 1/4m had been secretly earmarked for a new jail...)
So, if I am reading right, the good old holley into bridgport has 4 runners in the inlet manifold, but only two runners (one each rotor) has a wet nitrous fogger - and this is mainly because it is easier to fit, fiddle and tune the two versus the four. OK, fair enough - sure as heck can't argue with results!

OK, so my last silly question for the thread - I think there was a comment by you (somewhere) that for your engine currently in the build process, you will be extrude-honing the inlet manifold; would you take it so far as to have the inlet and ported plates & housing all dummy assembled and have the whole thing honed as a unit, or are you pretty happy with doing the porting seperately.

Judge Ito

I just got done match porting the lower intake manifold to the engine. Looks pretty nice. I will only send the manifold to get extrude honed. Soon Ill have updates on the Rx3 posted here.

Hmmmm, interesting. U minde me asking who's doing it and what their charge is?

Theres an Extrude Honer in Pennsylvania. Not sure of the exact location.
I think the shop is actually called Extrude Hone. I'll have to check up on this.

Judge Ito

I posted the extrude hone website and some moderator took it off. But yes there is one company in PA and a sister company in California.

JR and I were talking about Jason (JT Imports) Extrude hone job on saturday.
Do you still have the link for the website?

I am looking for N2o for my 13BT in my beetle
Problem is I live in South Africa and no one here recommends N2o on any 13b nor 12a
I can get N2o kits but wont know if its right or not and then there is no one to fit it
Could you assist me ?
I am sure i will be able to order and install N2o with some advise and help
TIA
CK
PS:Current setup is 13Bt STd turbo, injectors, MTX 8 microtec CPU

judge,
I am building a rotarized BMW. I choice not to go turbo once i heard about the puerto rico holley & n2o 1/4 times.
I am running a 96 block rear mounted (so i dont need dowls with n2o, hopefully) its monster ported with ida throtle bodies, 4x810cc, fuel only microtech and full msd ign.
I havnt pluged the primary injector ports on the center plate, the intension was to run the n2o nozzel there. would this work? or is it easier to put them in the manifold? I'll be using a wet system with seperate regulator.
how much n2o can i run with out breaking it?

Brandt

Does NOS increase the amount of wear to the engine? Do rotarys accept nitrous better than v8's.

Judge Ito

Update on this car that I started this thread about. Recenlty ran 9.0 @143mph exceding our expectations with this nitrous car.

Judge: That sounds like a good time, congrats! But what about Brandt's question? With your experience does the juice eat up an engine? I have heard from a person that has used it before and they said it doesnt hurt engines if used correctly. Then I have heard people that dont have experience say it tears them up? Obviuosly, I always beleived the "Master Tech" that told me it was harmless, but always had in the back of my mind it could tear them up? So wassup, what is you thoughts on the subject, Mr. 9 seconds ! ! !

i would also like to know how safe nos on a rotary is, the rotary seems a little bit better built for the use of nos. ive personally seen piston motors that used to much nos have oval cylinders with round pistons and tons of blow by becuase of nos. mainly from the rapid freezing and then intense heat from the combustion. and the tempture changes after time warped the block. will it do this to the houseing? what have you seen?

bejbis

btw, that was on a car shooting a 250hp dry shot, witch is a little bit overkill on a v8 not really tuned for it. and he did it for years before you could really tell any ill effects on the motor.

813KR$

Dry shot! I have heard dry shot is a KILLER! Got to have plenty of gas for all of that oxygen ! ! !

That is what I have heard anyway!

Brandt

I whould also like to know what is better dry or wet nos.

12abridgeport

Just curious, what does everyone do to maintain the bottle pressure. I found it to be a really big hussle until i got the bottle heater.

Also after purging kit, bottle heater, and NOS kit itself it comes out to be around $750.

WET, Wet, wet!

N20 = more air = lean condition = high heat = engine damage, so you need to counter act the leaning out with Mogas, mogas, mogas! Mo Gas + Mo air = Mo Power! ! !

813KR$

$750 for what 150 hp shot, sounds like cheap power to me?

Judge Ito

I have been using N2o on rotaries for about 7 years. In all my years I have seen nitrous oxide when tuned to proper air fuel ratios not create any damage what so ever to a rotary engine. This car that we ran 9.0 with is a serious nitrous eating machine. I have taking the engine apart a couple of times to refresh internal seals(like apex seals,side seals,corner seals and springs) and have found every single seal in excellent condition. Nitrous, turbo and even N/A engines are all reliable or not reliable do to bad tunning. Reliability is relative to tunning. You need to properly ignition time and tune air/fuel ratios and reliability will be there. But if you don't time the engine correctly and your air/fuel ratios are in the Lean side you will melt any engine.

How much should I use on a streetported semi-PP 12a?

Don't want to be rebuilding it every couple of miles though, so I don't really want to put much strain on it, just something to give a little more "oomph" when i've got a ricer trying to race me

BTW this is in a trike

I was looking for the best place to run the nitrous Nozzle or Nozzles.

I really dont want to inject before the TB as the system will be a wet system.

I was thinking of using 2 Nozzles on at the start of each secondary runner at the plenum


here is a image

Thank you, Judge Ito for your response. That is what I have always thought, just never had the $ to put into action!

Chair Child: What is a street port, semi PP? PP = Peripheal Port I dont understand how you can have a semi PP, maybe you mean BP = Bridge Port? Half BP half SP. You dont need da juice to beat a ricer ! ! ! Bridge port would do just fine! **** a good running SP will beat any ricer!

chairchild

when i say street port semi-PP setup, it's where you keep the normal side ports (which would be streetported) but you have a relativeley small PP in the housing - only around 1"

All this means is a better idle (and not at 2000rpm!!!) but with the higher flow capabiltiy of a PP. Oh yeah, and I can get a supercharger fairly cheap as well. with a late-timed PP, this will work extremely well.

And as everyone knows, ricers respect N2o, and usually wont even dare race you if you tell them you have it - thats if they aren't already put-off by the exhaust going

Oh yeah, theres a damn fast car around me, and I want to race him when this trikes' completed
