1000hp N/A LSx

[1Kurgan1]

This thing is flat out unreal, wish they had up some more videos.

I bet that sound would blow your head off if you hear it in person!

[1Kurgan1]

lol, yeah, that thing has to be extremely loud, what impresses me is it's only 433ci, I would have really expected a bit more, the LSx block can hold up to 482ci. Another crazy thing is that beast runs to 9600 rpms, 15.5:1 compression, it's a monster. It's also crazy how fast NA makes power, no waiting for boost or anything, that barely picks up any hp over the entire curve, crazyness.

[Wile E]

NA doesn't really make power faster than FI, just more predictably, when compared to turbos. Superchargers and n2o both make power in the same fashion of a NA motor.

Once you get it into a car, a 1000hp properly geared and hooked up, is 1000hp properly geared and hooked up. Methods don't really matter unless you need to fit into certain class rules, or just want to explore a specific type of combination, for whatever reason.

And, despite how awesome an achievement 1000hp from a NA 433 is, I would rather not rev my LS that high. lol. I'd rather have an overbuilt 500hp motor, and run 15psi thru it for 1000hp at a much more sane rpm. lol.

With n/a you still have to wait for the cams to "clear" or cam to get in its powerband

Yep, there is that as well.

[1Kurgan1]

NA does make more power down low than a centrigual sc or turbo as one needs rpms to build boost and the other needs faster moving exhaust. Granted trans braking will be involved so it doesnt matter much. I also didnt look to hard at the dyno chart off the bat as I was just shocked to see that from a 433, but it starts at 7500rpms, lol. So it might not have that low end power :p

I agree this would never be a path I took, building a stout motor thats not crazy then throwing boost at it and hitting 1k hp on an LSx honestly isn't too hard, which is crazy to say. But this isn't a street car with 15.5:1 compression. This thing is going to demolish in the NA bracket. The LSx motors are just amazing, as everyone else moves onto over head cams, GM sticks with it and really came out with a winner, funny to watch LSx's pull other things up top. I dont think I can resist LS and RWD, most likely have some LS powered vehicle in 2 - 3 years and sell the GTX, or keep it stored for my son and demod it a bit so he doesnt kill himself when he gets his licence, lol.

Insane RPM. FI is better, less overall stress on components, I want to see a 1500 RMP through 9600 before I call it good, the torque was falling off quickly at the last, so a high RMP start will stall. Which could be good for hooking, and bad for launch.

A guy working at a local Napa has a 800HP camaro that he has more problems on launch with, and so he still runs a measly 560HP 5.0 supercharged as it can hook and launch.

[1Kurgan1]

800hp is a lot of power to hook, even 560 is. Thats why most videos you see of cars 600who and more are roll races, because most of them dont run around on DRs. got to say I'm surprised anyone at your local napa has a fast car, the people who work at mine all just seem lost, couldnt tell the difference between them and a cashier at walmart.

Same with my local auto parts stores, but I have to admit, the Napa guys are a little more knowledgeable than the Advanced or Autozone people. Not like that says much tho. lol.

[Steevo]

Good parts peopel are hard to find, and keep. I did it and still do it to help out, got in trouble a few times for doing shop work on the counter, like rebuilding a carb and making our shop look bad.

Autozone people are stupid, point blank. They fit better at McD than a autoparts store. We ahve one great guy at our Napa, he will find things, and knows how. The others just shrug unless you want something common.


560 isn't too bad, I drove a friends BMW that he had turboed and it was making 400+ and would almost lift the front end off the ground. But he was crazy, he raced sportbikes, and worked as a Iowa State Patrol. I bought my pickup off him, and after I got it tuned correctly he borrowed it to go get his sister in Iowa, drove 100+MPH across I-80 with his radar detector, made it in 6 hours. I got the use of his BMW, fair trade. :yes: He is also the one who convinced me Pirelli was a awsome tire.

My local autozone has a guy that really knows his shit, but I know more about Chevy's than he does. Orielly's is another story though, most everyone there knows exactly what they are doing.

Pirellis are nice, but mostly overpriced.

[Steevo]

They are great. Twice as nice as Traction TA's and many others I have run. But they wear out quick from being soft.

That's all high performance tires. BFG G-force T/A tires are better than most pirellis in grip. You pay a good bit for the Pirelli name. It's the Prada of tires.

heh, you first world people, all we can afford is maxxis

Not so says I. After having a pair of P6000 and TA's on my car the cornering ability of the Pirellis is second to none i ahve found yet, a friend runs them on his Cobra after running TA's, and many others, my friend used them exclusively and had track times to prove a set of perellis was faster.

Not only do they hold a corner, but when they do break free, it is very linear and smooth, unlike most otehr tires I have experianced where your ass puckers so hard you have a permanent mark left in the seat after a good day of mountain driving. A new set on the BMW and I was taking 15MPH hairpins at 55MPH and pulling smoothly out of the corner with a bit of drift. A pair on the olds and brembo crossdrilled and slotted on the front and I was able to make a friend fear for his life coming down pikes peak road. We had to stop as even with a synthetic brake fluid the brakes were fading.

I ahve run a few pair, and have tractions TA's on now, give me Pirelli!!!!

Traction TA's are not G-Force TA's. G-Force TA's > Pirelli

[1Kurgan1]

Tires can only make up so much for suspension, that olds once again sounds like it was made by jesus, I need to see pictures of it why so crazy on the slotted/drilled rotors, drilled really doesnt help do anything but crack the rotors. I do agree Pirelli makes great tires though, but theirs a lot of competition out there thats just as good if not better.
