Sean's no longer on this forum, but I talk to him pretty regularly, as we work together.

Nitrous on a TII doesn't really make sense, given the already existant creep issues. The addition of nitrous gases to the system would cause creep on any stock wastegate, no matter how radically ported.
Sean played with it because he was ******* nuts. He's EXTREMELY lucky he did not blow his engine, considering his boost conrtol issues on a disgustingly large port job on an S5 wastegate.

BTW... I am pretty sure he still answers his email at shutup_billy@hotmail.com.

 

Does anybody know which injectors to upgrade to, to provie adequate fuel for a 50-75 shot on an S5 NA

 

I'm bringing this one back i know! A friend of mine is going to be installing a wet kit, where should we be getting fuel from?

 

Denaturing with sulfur dioxide results foul odor and lung irritation by forming a mild acid. It remains sniffable.

 

Bringing this back from the dead in part because it deserves a bump and in part because I have a question. I knew to the FC's intake system, does the car have a MAP or MAF sensor? I the 2nd case, I would guess that the MAF would pick up the increase air flow and temperature drop and compensate the fuel correct? (assuming injectors and fuel pump are in working order).

I'm not new to nitrous by any means, just to rotaries, anyways would a 25 or 35 hp dry shot be a problem for fuel compensation? Yes that's all I want a nice small shot, to complement bolt on's and give around 200hp at the crank. That would make me more than happy

 

Both. The primary load sensor is an AFM (but a flap type, not a MAF (hotwire) type), and there's a MAP sensor for secondary functions.

No, becasue nitrous doesn't increase the airflow into the engine. Nitrous is an oxidiser (it contains it's own oxygen) which allows you to add more fuel. More fuel burnt makes more power. The extra fuel must be added by the nitrous system and the fuel pump must be able to keep up with the extra flow. If you're familiar with nitrous you should know this...

 

speakn of n2o could you run like a 10shot for a full 60 seconds for like a autox?

 

irunning a full shot of N2O in an Autocross would be dificult since the SCCA doesn' t allow the use of Nitrous. Last I checked it was illegal in both Solo II and Pro-Solo. Don't know about the other classes but I expect the same. Although small, a shot of nitrous is really abrupt and rather instant. mid corner it'd be tough to compensate. I would spend my money on grip instead.

 

I respectfully disagree, yes nitrous oxide is an oxidizer that breaks down at over 500 degrees, however the initial exposure of the liquid to the ambient atmosphere, will drawn in alot more air.

Because nitrous is so cold; it absorbs alot of heat around it, thus condensing the air that is at atmospheric pressure and increasing the air flow. The air entering the manifold is alot more dense because of nitrous use.

Thank you for answering my other question though.

 

Copied to Archives.

 

Yeah, it's true that colder air is denser and that this will increase airflow, I'll give you that. But even if the nitrous dropped the air temp from say 25degC/77degF to 10degC/50degF, the density (and hence airflow) would only increase by less than 6%, which I'd only call a small increase, not "a lot more air". This would easily be compensated for by the stock EFI system.

 

does anybody actually use nitrous on basic NA 13bs yet? I want some numbers =)

 

Hi scathcart , I have read your post about nitrous and it is
excellent, it helps a lot.

I would like you to help me, this is everything a have:

I hope to get 500 to 550rwhp from it without CO2 or NO2 on the intercooler


I was thinking to use the 2 systems: the spray bar and direct wet shot
with a switch that helps me choose witch one I want to use or use it both at the same time.and also use the spray bar as purge system

I'm Planing to buy this on Ebay: ( it's not from NX, But it's very
difficult for me to buy parts at the NX web page)

http://cgi.ebay.com/ebaymotors/ws/eB...9519&rd=1&rd=1

My goal is to get from 650 to 700rwhp, so I'm guessing I would need a
150 wet shot or something like it...

What else or what do you think I need to get for my goal?

I would appreciate any help. Regards, Blade
