The Ultimate Thread

[Saladin45]

Ok. I would like to get the best of the Hotair minds together in this thread to help me and help one another who wish to put their hotair vehicles to the fullest get some useful information. Hopefully, this will help some of us, if not all of us, in our quest for entry into the 10 second club. Now, who's with me?!

Alright, so this is what I want to do. Obviously, I want to get a hotair that will drag me into the 10 second's. I'm shooting for mid-high ten's. But firstly, I'd like to know what it is in particular that holds back a hotair Grand National from being able to reach the potential that it's brethren of the later years have managed to achieve.

So in the other thread we managed to get to the point that the fastest known hotair got 10.8 on the 1/4. So that's not bad, but what I would like to know is, was the car still using a radiator? And if so, if you took a radiator off, and installed an intercooler, would it have made any real difference?

Another question. With the airflow into the car of an 84-85 GN. What stops the vehicle from being able to get as fast as the 87's can? What about the flow of the air causes it to have such problems as the ones that you guys were talking about before? And here's another question. What parts of the car would need to be replaced so that airflow would be better, if not completely fixed? (If there's no fix, someone explain to me why)


I really would love to see how fast I could get one of these vehicles. Let us have a meeting of the minds, shall we?

ok maybe you should start reading from page one of "Why Hotairs Are Slow". we cover 99% of your questions there. the reason i wanted you to start a new thread is because you started talking about installing different motors and was taken that thread off course. Anyways There is 2 ways i can think of to getting a hotair into the 10.50 range but its going to cost alot of $$$$$ if you keep it a true "HOTAIR".

as far as this question you asked i am lost. is this what you really ment to put.

So in the other thread we managed to get to the point that the fastest known hotair got 10.8 on the 1/4. So that's not bad, but what I would like to know is, was the car still using a radiator? And if so, if you took a radiator off, and installed an intercooler, would it have made any real difference?

if so yes it was running a radiator and yes if he did put a intercooler it would make a huge difference but to take the radiator off why the hell would you want to do that?

anyways i would start reading every post you can in the hotair section and you will learn alot about these cars real quick. if you have futher advanced questions there are a few of us on here with alot of knowledge. Not to sounds like a dick but from what you posted it looks like you dont know to much about these hotair cars and what makes them tick. Anyways i wouls start reading posts in the hotair fourm. i would start with why hotairs are slow and that will give you alot of info real quick then read other posts.

Yes, I am very new to hotair's and Buick's in general.

So bear with me if I sound like a total noob sometimes. Because... I am.

Also, you said that it would make a huge difference if he put an intercooler on the car. Question is, why wouldn't he want to do that? Wouldn't that make it better for airflow? Or is it really very minimal when it gets down to getting the car faster?

im guessing he didnt do it due to the fact he was keeping it hotair. he then later switched to the 86-87 model engine and has gone from there. To me there is no real reason to intercool a 84-85 if your going to do that you should just start with a 86-87.

Yea..dont worry I dont understand WTF hes talking about either :biggrin:

But anyway, for a 10 second hotair GN, your looking at spending 10 to 15,000 dollars. Save your lunch money.

That fastest hot air was on a stage two block as well, right there is the majority of your cost,(the extra cubes are what helped him achieve the 10's) you will almost need the extra cubes just to get into the 10's that deep.(as well as consider a stroker motor) Not to mention if you're replacing the radiator with an intercooler it's no longer a hot air. Not sure how big of a set up you're thinking here, I'm sure anything is possible but how much money do you want to spent to get there? I am pretty happy with what I've achieved using a stock block, crank,rods and stock heads that have been ported and polished with bigger valves and not being a stroker set up. I'm not sure how much more we can hope for as a hot air not using alcohol. Time will tell
