I was just reading thru a hot rod mag and read one of the readers letters........

it said musi will not race in the PRO series because of the obvious bending of the rules toward the turbo cars,

what he is talking about is twin turbo's being counted as one power adder...........he doesn't agree and call it having 2 adders...

now the part that got me thinking was, the intercoolers....

he is calling the intercoolers power adders too. saying that the turbo guys are getting away with running 4 power adders to his one.(the guy that wrote the letter had a 14-71 high helix blower) fuel in, fuel out, as he said it...

the twin turbo thing I think is up in the air because I've heard alot about one being better anyways...........

my thing is the intercoolers, seems to me that a air to air intercooler isn't but that's not what the big cars run.

they pack these big coolers, mounted inside the car with dry ice just before every pass. that seems to be like adding power from a 2nd source to me. and its not even just ice water, that doesn't do well enough. they always use dry ice.

now with the turbo cars running drag racing right now, what would happen if they had to remove the intercoolers or at least only have big air to air ones. killing aero on the big end. would they still own all?

 

I don't know if they run alcohol on the blower cars in that class.......


I don't know much about the class he was talking about, I'm talking about stuff like fun ford's 10.5 tire classes and stuff like that.


I'm guessing they wouldn't allow n2o to be used instead of dry ice to cool the inlet temps down, I just don't see the difference. pack it with dry ice or cool it with n2o. what's the difference?

 

I say 1 turbo for every nozzle
just my 2 cents

 

Think about it each nozzle is adding nitrous they should only have one nozzle and one stage.

 

i think this is a good question, but would be better suited in our power adders forum...

But to answer the question, in my opinion 2 turbos should be counted as one power adder because most people know, its usually more beneficial to run only one large turbo, I think the main reason alot of people use twins, is just for bling factor, and ease of installation etc...

But in my opinion, to call an intercooler a completely separate power adder is just retarded...

Think about it like this... Turbos run off of exhaust gasses to make power. The turbo, being that it is basically one piece, retains all of that heat from the exhaust, and it spreads to the compressor side, which drastically increases the temperature of the charge in the compressor. I would imagine intake temps. increase from 100, up to 300 degrees, just from the time it enters the compressor inducer, to the time it exits.... An intercooler is neccesary to cool this air, to efficiently AND safely make the power from that compressed air... Its basically just a supporting mod... That would be like, banning bottle heaters on nitrous fed cars.... Granted, the dry ice thing might create an unlevel playing field, because when put into perspective, thats almost the equivalent of nitrous guys using blow torches to heat their bottles, which as far as I know is illegal by all sanctioning bodies...

So maybe they should be told to just stick to ice and water, but to completely ban a liquid to air system in favor of an air-air would be ludicrous.... I personally like the idea of the dry ice, and having intake temps. below the outside ambient temperature... My hat goes off to whoever discovered that....

 

Bottle heaters are used to bring bottles up to pressure, torches can weaken the metal, it's a safety issue, not a power adder issue.
While I'm still undecided on this one, I would like to point out that a turbo can be used without any type of intercooler at all, just the boost levels have to be low, or an alternate fuel needs to be used. So I guess in a twisted way, an intercooler could be considered some sort of power adder, especially if using an additional chemical/substance to make more power. I think the turbo cars would still be able to do well with air to air, and it may make things a little more competetive for the nitrous cars. Hmmmmmmmm............

 

I don't think the intercooler its self is a power adder, just how its cooled.

there's no trade off with using dry ice. and its an outside source, which makes it a adder to power.

now a big air to air, hanging off the front. there would be loses due to aero and psi drop because of the size needed to cool the amount of air there pushing thru. and you didn't just introduce a 2nd source of power........I.e., dry ice. even with just water you would need a heat exchanger in the wind some where.




"InsaneCivicSedan "

of course they like having ambient temperature below the outside
air temp, we all like have and unfair advantage over the other guy when you race him, I know I do...


and yes I say hhmmmmmmmmmmmmm as well,

I really think the nitrous cars would be the faster one if they changed the rules.


I really like the turbo cars, so I'm not sure if that's what I would want to happen..........

 

If they don't level the playing field then everyone will be using turbos, what fun would that be?
