What do you guys recommend as the max redline to run a stock 2v at before you start into the "dangerzone"? I currently have my SCT revlimit set at 5900 for safety. Am I being a bit to timid? Does it even matter until I get cams or other engine components that can take advantage of the extra few hundred rpm's? Thanks.

I never run my car past 5200rpm, my max hp is at 4600ish and torque at 3200ish so I just shift at 5k in a run.

the stock redline should be your redline on your stock motor. there's a reason its there

+1, don't go past 6,000 RPM

Yes you are being too timid. Move it back up to 6250.

Umm safe stock redline is at 5800 on a GT, fuel shut off at 6k. Move it up to 6250 and good luck I wish your car the best LOL

my buddy shifts at 6200 all day every day...he has vt st1 cams/lt's and other small stuff...he's been doing it for 3 years. i don't go past 6k but i have an auto

Yeah, I've heard that it is relatively safe to run the stock internals to around 6100 rpm. The rumor is that most won't have a problem with this but that you are still pushing your luck past 6k. Hence my reasoning for the thread. Just wanted to get others opinion on it. I've had my car to the revlimit of 5900rpm quite a bit and I don't have any problems (yet). But I run mobil 1 oil and I suppose that's gotta count for something. Along with regular maintenance and pampering. Crap, with the 4.10's I almost can't shift outta 1st quick enough. It gets up there freakin quick!

As far as know, the mechanical limiting factor is the valve springs. Also, your stock oil pump is sized for the heat generated at stock rpms... more rpm = more heat from friction.

I'd check with your tuner to see what the practical power gains are to be had above stock redline (if any). I wouldn'tgo above stockunless a trusted tuner agreed with the idea.

I run the fuel cutoff at 6250 and try to shift at 6000 RPM. The PI 4.6L should peak around 5500 stock, but you need to take it past that or when you shift to the next gear it will drop down too far in the RPM band and fall out of the powerband.

I am running aftermarket valvesprings, but so far as damage occuring I think your pretty safe. Considering I am running a FI engine (and RPM kills FI engines) 6250 shouldn't throw a rod or anything stupid.
