12psi Vortech Cobra vs 4400 lb land whale

[SSMOKEM]

hey Unit 5302,

Well, obviously the calculator is flawed, because picking up 155hp on a 125 shot isn't normal

If you read my post you would notice I said 75hp 1st stage and 125 hp 2nd stage. This gives me a total of 200hp. Since the N2O is on around 9 seconds during the run, this gives me an average HP boost of 150/160 over the run.

From my knowledge the LT-1 has aluminum heads, not iron

I guess you need to go back to LT1 school All 94/96 Impalas came with the iron heads on their LT1s. They have higher stock flow numbers than the aluminum heads, and less compression. Stock is 10 to 1, mine are 10.25 to 1 due to milling the heads. The only drawback of the iron heads is the weight.

If it had iron heads your engine would be gone with running a 125shot on that kind of compression.

Iron heads are much more capable with N2O than aluminum heads and generate more power because they retain more heat. Detonation is avoided thru the reverse flow cooling feature of the LT1s. My buddy Jorge is running 11 to 1 compression on his stroked LT1 and a 250 shot. Of course he's MUCH faster than me

Running the stock bottom end and rear end? Sounds like you're lucky to me.

I've been running the 200 shot for 2 years and over 120 track runs. I'm sure you'll agree that this is much more than just luck. The stock Impala rear is an 8.5" 10 bolt. One of my Impala buddies pulls mid 1.5s, and my other buddies get mid 1.6s on it. I don't generate enough power to break it since I've never gotten into the 1.6s.

As a matter of fact, I still have the original Auburn Posi that came with the car. I now have 57000+ miles on it and it's still smoking both tires

Oh well, looks like you've go the numbers.

Hard to argue that

By the way, out of my little group of 5 Impala buddies, I'm the slowest, but the only one still on the stock shortblock, every one else is already stroked.
