Nitrous Done With ? Turbos / Blowers Taking Over ? Cars soon going 5's in the 1/4 ?
 

Below is a link to the whole artcle, I posted the things I thought were key points from the article. Very crazy to think of these cars getting into the 5's in the 1/4 ! :eek: Looks like forced induction is starting to take over. :D

When I heard the new rules that were being proposed for the 2005 NHRA AMS Pro Mod series that would essentially eliminate nitrous oxide-injected combinations by taking 100 lbs. off the minimum weight for blown cars and increase the maximum overdrive to 29 percent, penalize any car with current body styles by adding 100 lbs. to their minimum weight, and, if the rumors are true, would legalize turbocharged engine combinations, I freaked. Basically these rules if adopted by the guys in charge would sooner than later turn NHRA Pro Mod into a five-second blown or turbocharged class. :eek:

I especially got worried about the rumored turbo rule when I heard that Stephan Papadakis recently ran a 6.541/211.73 in a 183 cubic inch, twin turbocharged, V-6 powered Don Ness built Honda Civic then backed it up with a 6.55 ! :eek:

Yeah, let's up the overdrive, reduce the weight and allow turbos, and everyone will be in the fives. Turbocharged engines in the hands of guys like Howard Moon, Chuck Ford, Darren Mayer or Jim Oddy won't be faster than any other combination, will they?

If they weren't it would be the first time in the history of auto racing that turbos didn't dominate a class once let in. :D

no more pussy juice,i mean really engine vs engine,mech vs mech.i mean any idiot can throw some NAWZ in the trunk.

Are you serious?
Let me see you tune a twin fogger setup pushing almost 1000hp in juice without hurting anything...
Hell, let me see you do it with a single fogger pushing 500hp.

Turbo combinations are definately more efficient at making power, but in an 1/8mile race i think it's still pretty close since the turbos will make the majority of the power on the back end.
In the 1/4 mile it's going to be tough to keep up until they come out with some advancements for nitrous as the power is just raw..

just take it from me, nitrous is just as complicated as a turbo setup. i got my ass handed to me a few months ago for thinking like you :lol:

Yes any idiot can throw a kit on that is running under a 200 shot but above that you have to watch the tune pretty dame close which means your run of the mill idiot is not going to be able to cut it.

Personally I do not see how you can beat a turbo set up in any aspect. The power is always there but at the same time you can putt around easily, much easier on parts, and they are very effecient at making power.

Only an idiot would call it NAWZ :razz:

still safe or unsafe any idiot can throw NAWZ in the trunk



any idiot CANT go into an engine and do some real work,and that what i respect is the tech part of it.

Actually, rather than just play games here, please, tell me what is so simple about a substantial gain of horsepower from nitrous?

and there in lies your problem..

you'll get no more power from throwing a nitrous bottle in your trunk than you will throwing a turbo in there..

its up the engine where it counts.. and nitrous is not a simple thing to put on when your talking the power levels your talking here.

putting a turbo on a honda.. nissan or anything other road going car to add 100 hp is a totally different story to making 1500+ with a turbo ..

ignorance is bliss.

nah it's not bliss.. it's type-j-spec.... :)

wow......what ignorance!:lol: We arent talking Gandy rice cars here.


But as to the original post...I think they should let Turbos in that class and keep the restrictions to a minimum. If nitrous ends up not being competitve...so be it. There are many other classes nitrous will always be competitve in. Turbos are still advancing....I would like to see 5 second Pro Mods.

Kinda crazy they arent far from Top fuel cars but on a lot less power.

I have a friend who relies on pure nitrous and carbs as his setup.His old car ran mid to low 8's on a 250 shot.He sold the car and plans to redo another nitrous/carb setup.Turbos will always make more power but he seems to be more consistent with nitrous vs turbo equipped cars of the same weight.These cars i'm reffering to are little rotarie powered buckets.

thats my point



and if you have the money and know how to build any engine for alot of juice then you can go from 200 shot to whatever and all you have to do is THROW ANOTHER BOTTLE IN THE TRUNK.


and using NAWZ is meant in jest buick.



when using more boost from a turbo you are going to have to do alot more then that.am i wrong.

Geeeze anyway back to the topic at hand. It will be interesting to see where this goes since nitrous has such a strong hold in many classes for so long but seems to be losing ground to turbo systems that have only started to rise.

Sorry to spoil your blissful ignorance, but there's just a little more to it then throwing another bottle in the trunk when going to a bigger shot..

Of course you can't seem to get beyond the FNF mindset, so I'm not going to waste my time.. If you were serious I would take time to list some of the issues that you need to get into with nitrous to make it work properly..

Scott, Turbo's are definately the power adder of choice at this point in time, but with anything I'm sure there will be advancements made in the nitrous field that will allow them to better compete with the turbos.. Right now on a SB, there is pretty much a limit to the amount of nitrous a motor can handle without coming apart due to heat/cylinder pressure...

We'll just have to see how it goes, but it's going to be interesting..

I think there will be a limit on nitrous...if its not already there. The advances made with nitrous will be in its delivery...and to the motors themselves.

But I see it as NA + nitrous = engine running on vacum. Volumteric efficiency has a peak. Basically if all the mass flowing into the motor was nitrous and fuel. That would be about it in terms of max power.

We all know motors are nothing but pumps. Think of it in terms of pumping water through a pipe. If you put the pump at the end of the pipe and try to suck (vacum) the water to the end...there is a limit that will be reached since you cant have more than absolute vacuum on one side and 14.7 psi on the other. PSID max will be whatever ambient is. Nitrous would be like making the water 1/3 more dense...thats all.

If you place the pump to push the water out from its source...the sky is the limit. 15 psi...30 psi...3000 psi..whatever. In car terms you just need to figure out how to control the cylinder pressure through available fuel and tuning to see what pressure you can get away with.

For all out engineering in the top classes with no holds barred...I think boosted cars are going to continue to advance at a much faster rate.

I dont belive that quite applies to the lower classes due to money required for some of this stuff.

And on the street...nitrous is still KING! :D

if your going to explain something then do it,i am very open to hearing what you have to say.what im saying is it is harder to make a car faster without nitrous,and cost more money.im sure handling that much juice isnt easy but its kinda cheezy in my view to go get a refill and turn a slow 150hp + juice into 250-300hp(with built internals)but thats just me.

I do not know how much longer nitrous will be king on the street. :D :evil2: Given the trickle down effect that happens when Pro classes start to figure out various combos and make new advancements in controlling detonation it is bound to become more plentiful technology for us average folks. Heck I remeber posting about a similar topic years ago here on TR regarding how many auto manufactures were moving to boosted applications to make power. Now look at Benz, Mazda, Saturn, Mopar and so many more. Again as it becomes more mainstream it is bound to help all of us using turbo applications.

Afterall controlling detonation is the key to any combo when you boil everything down. The rest of this decade should be interesting to see now that 500 h.p. from the factory is becoming more regular.

Fine, you gave us your view and nobody cares about your nitrous comments. You can quit now.

It certainly looks like turbos are taking over. Are they ever going to let the top fuel dragsters go with a turbo setup? Will there ever be 3 secs 1/4 times (if physically possible)?

They are not talking about cars that make 150hp...
we are talking about cars that make 500+whp with a 300+ shot on top... its very complicated, trying to get the cylinder pressures stabilized, and making sure you dont have a lean spot in the fuel curve (lean+nitrous=dead engine). Factor in the timing controls required (retard box, window switches, failsafe switches, etc...) and you have got yourself in quite a chunk of change, eh? Not to mention the better kits (read: fogger) are $$$ themselves.

No one cares about a 250-300hp, its not fast.

Jspec, you just don't get it and you won't. What your'e talking about for power levels may be fast to you, but my wife's Expedition makes more power than what you're talking about..
Each system (turbo and nitrous) are both complicated in their own rights, just different ways of making power. If you would like, sometime after the first of the year I'll meet up with you and my slow nitrous powered car. We'll go ahead and race for the fun of it, sound good? I mean, it's only a nitrous powered car and I only have one bottle in it... and god forbid it's only a mustang...

Jspec...no one will explain anything to you because you dont have enough base experiance with what most people are talking about here. It would be a waste of time. Build somethig fast and in about three years get back to us.

BTW...wanna run me on motor when my car is done? I will not hit you with the 400 shot. Just what the motor makes.It will be a pussy 150 hp all motor combo :roll:

That's it!! Next track day the Buick is going to go 9's!! All I have to do is find another bottle............................

Will always be king on the street until turbo setups can be put together for 500-1000 without the help of a junkyard. :p
