Racing 392 soon need advice!

So my step dad just bought a 392 challenger... I raced his older r/t (closed course in Mexico and smoked it of course... But I told him when he buys a 392 we would race "stock for stock" well he actually bought it ...I'm thinking some super sticky drag radial and maybe a tuner with a stick tune still but raised rev limiter, anyone have any advice? I just want to keep up lol

Driver will be key. They have a slight advantage from a dig stock t o stock. DRs and tune will handle that for sure. On a roll stock vs stock it will have more advantage. Nothing the tune shouldn't fix.

Tune and slicks sounds like a plan! I'm thinking it will still be a drivers race... And he did have an 11 second firebird in the 70s and definitely knew how to drive it... I'm ok with losing but I'd like to at least try and enhance my chances lol

Having a 11 sec car then going to a differnet one he will need some practice though. Get him before gets used to it. DR's/Tune sould help you edge him out pretty easy.

I have already beat my friends 392 challenger a few times when my 5.0 mt82 was stock. We went out to a back road and did a few different speed races and I won all of them. It is a drivers race and the mustang is easier to shift fast. We switched vehicles and then he beat me, I found it harder to drive than my Stang. I don't care what Internet says the 5.0 is faster and I have never see a 392 run faster than the 5.0 at any track. Only read its a bit faster online. I go to my local track quite a bit and watch and there is a few 392 challengers that go and I have never seen then pull of a better time then the 5.0.

Of course you did.

Also note street racing is not liked here.


anyway here is the list for the 392's. These acrs are not doing bad at all being no tunes are out..

Now show me stock 5.0's running these times. Cause that is real measure in performance. Not your BS stories with no proof of anything.

---------- Post added at 09:03 AM ---------- Previous post was at 09:01 AM ----------

Fact is the 392 is faster. And looks to be easier to drive with more guys going low 12's then 5.0's.

Re: Racing 392 soon need advice!

Both 392 and 5.0s are great platforms to build from IMO. You're right, for no tune available they're are holding their own. I did race one in Atlanta drag for test and tune vs my bimmer with meth and beat it bad. He only had drags though. I don't like dodge, but take it over my bimmer.

Thx for helping my point bud. I see only high 12s with a stock 392., which the 5.0 does faster. So again like I said its a drivers race. Also note the same story of your drag race or nothing you know all isn't liked here.

I've never heard of a bone stock 5.0 running a 12.2. And neither have you. You just want to argue with wnt2gofst to fulfill your hard on for him.

We also have to factor in that I can't launch for *****... I'm thinking my top end will have to save me, would a boss intake on an otherwise stock (tuned of course with a raised rev limiter) car with 3.73s help?

Also if I have sumi htr z 3s what RPM should I launch at? I'll practice for sure... I have dynolicious on my iPhone lol

I might get some nt05s with the tuner but not sure yet if the difference is only marginal between those tires

Get some real Dr's. Down low is where you want to shine. Beat him out whole and be gone. 392 makes more power and will shine top end actually.

You want NT05R's. But even better would be some MT Dr's.

Any drag tires will be a night and day difference from the stock tires! But a would stick with the nitto or something like it so you can actually use them for a while on the street.

Those should work great. I ran a 18" MT on 10" wide rims. They hooked great. Drove them on street also NO ISSUES. Only time driving on street sucks is in a decent rain.

I have ran Mickey's on the street no issues. And the nitto don't hook as good as the MT or the M&H. I have tried them also.

I said that because the nittos lasted pretty long on the street for me and the op is doing street driving

That is a good point, this is a daily driver first and a track car second but I would be willing to keep those short lived sticker tires on for this one race and then taking them off again lol

He's being a little hesitant to race though, not sure what his deal is... all the youtube vids of bone stock 392s show them connecting really well with stock tires, I think these radials are a definite upgrade for me and maybe a tune with a raised rev limiter

I know he's doing a cold air intake right off the bat but there's no tunes out for it yet

It won't do you any good to have a tune w a raised rev limiter if you don't get the boss IM.. The stock intake falls off drastically after the factory limiter..

Actually I read a full article on this idea and there was a breakdown of how much power you're actually putting to the ground at different rps but also factoring what gear you're in. It was explained that even if the engine is starting to lose power at high RPM, you're still putting more thrust to the ground than you would be if you shifted up to the next gear because you're now in a higher gear and even more power is lost... also you are shifting into the next gear closer to peak power than you would be if you shifted out at the stock shift point... I'll try and find the article it made a lot of sense.

However, obviously the boss intake would make a huge difference in addition I'm just not sure if I want to go that route yet.

Here's the article it uses a dodge neon for the example but there's a similar drop off in power at high rpm:

Horsepower vs torque

I know he's doing a cold air intake right off the bat but there's no tunes out for it yet
Just my street tires I have now give me awesome traction compared to the stock setup! I run 20inch wheels and a 255 front and a 295 rear. As long as your at least a 295 width in the rear even a street tire will work good. Obviously not launching at high rpm on a drag strip but on the street there is much more grip on the rough road. I know it's all drag this drag that on this forum but any 295 or wider rear tire will greatly improve your traction. And even a nitto nto5 will work good, or a nitto nto5r but that one will have less tread life and over all street performance. I also love the nitto invo tires they have always worked well for me and I had them in a 305 rear and I got awesome traction. And in regard to a tune. No need to raise your rev limiter! Any canned tune from the reputable companies will give you enough to kill this 392! Trust me

Its always good to shift above peak HP a few houndred rpms. This will help keep more in the power band. But the stock intake peaks before 6800 and starts to fall off hard after 6800. That why no reason to go above 7000.
