What do you guys think?

I didn't put it in the GTR tech section because It's just a video that keeps popping up on youtube that I want you guys opinion on.

Is it dead Jim? Or is it just some monstrous super cams? I'm leaning on FUBAR, but theres so many mods that make some unnatural sounds sometimes lol. It just sounds like bad compression to me, especially when the engine nearly dies at idle.

But hey, Imma noob, whad'I know?

my car does this exactly, get a good rev and you can almost stall it. cams are to blame

I knew I had to be wrong, figures! hahaha you must have a hell of a GTR then!

Ah well another thing learned.

anyone else notice the dash lights flicker when it almost stalls... i think whats happening with this car is some belt slippage, but that aside what hes diong is rather punishing on the car i imagine it wouldnt last long with this owner... and then they will prolly end up on some forum with the guy saying how skylines are crap

Also happens when AACV is dirty; solenoid wont engage quickly enough to account for the closed TB not allowing enough air to enter the circuit.. But yea, sounds like cams and exhaust-less. My car sounded like this without the cat back; only downpipe, which would account for such intense air loss off throttle from high revs, relatively 0 backpressure.

Why do they make them like that? I dont see that as something good.

Why wouldnt it last long? still learning

[hozer]

aggressive cams give you rough idles because they have a more specific 'optimal' RPM range. When they are outside of that range, they idle rough. Rev it up, hit the optimal, drop out get rough idle whilst falling and almost stall

When the car nearly stalls, the alternator is not running at rated speed therefore it's not charging as well and the load becomes battery powered. Nothing out of the ordinary when nearly stalling. Nice cams Nothing punishing about it other than beating on the electrical system a bit. Not everyone keeps the AAC. Some people get rid of it as it's a mess of hoses and weighs a bit. I'm still on the fence about this myself. I don't care for clean idle if I can save weight and room and reduce parts than can go wrong.

From what I understand, with more aggressive cams you have to run engine richer. But it depends on how aggressive cams are, as to how rich you run engine. Also from what I understand, get less vacuum with more aggressive cams at idle. That's why with BOV, have to adjust spring strength when fitting cams, as vacuum has changed. Also AACV needs vacuum to function. Combination of less vacuum, running engine rich would make engine struggle to idle.

Short exhaust won't make much difference (have tried this) and it idled, etc perfectly with stock cams. Just was really loud. But when combined with aggressive cams with low idle vacuum, running engine rich, it probably would cause problems.
