L99 to ls3 question - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

About to do a cam swap/conversion and my question is as long as the afm dod is turned off can the car be driven to heat cycle the springs and get it on the trailer?

bionick · 05-25-2016, 12:55 PM

Why don't you keep VVT?

Trob85 · 05-25-2016, 01:33 PM

Not the purpose of the car I have no need or want for it.

ClawSS · 05-25-2016, 01:44 PM

So the purpose of the car is to not make power. Got it!

ClawSS · 05-25-2016, 01:49 PM

Sorry, that was snarky. You do realize that you do not have to convert to LS3 to get rid of DoD, right? And getting rid of DoD is not converting an L99 to LS3.

VVT (Variable Valve Timing) is the best thing since sliced bread when it comes to a pushrod v-8. The added power under the curve for a phased cam timing of more than 22* on the fly is awesome even with the cam phase limiter installed and a big cam.

Don't see how having a tuned car making as much boost as it can handle and wanting peak power at all times is not making power but.....got it......it wouldn't matter either way the setup of the car is to launch at 3400 rpm when boost is beginning to build.

ClawSS · 05-25-2016, 01:55 PM

I understand...you are traction limited and can't handle the extra torque.

Trob85 · 05-25-2016, 02:26 PM

Yep sure am

ClawSS · 05-26-2016, 12:05 PM

yeah, well you will find that VVT loves boost. If your tuner knows the usage of the tables and has been schooled on the benefits, the percentage increases in managing cam timing on the fly, then you can pick up measurable 60' decreases and more significant top end trap speeds all from the same cam. Take advantage of the smarts in the PCM. Don't dumb it down just cause the LS3 has to force you to a set dial-in cam spec.

Trob85 · 05-26-2016, 12:39 PM

Well since it is my car I think I'll stick with the plan but tanks for the input.

ClawSS · 05-26-2016, 01:06 PM

You are very welcome. I hope your plan works out, but if you want more you can look at this list to see what others are doing when adding a poweradder. The L99 and VVT love boost of all kinds.

Do some research lots of people on here who did the conversion regret it. From what I see it's cheaper to keep VVT and more beneficial than the conversion. Can't get mad at people for giving advice. That's the whole point of the forum.

Trob85 · 05-27-2016, 06:29 AM

I'm not getting mad I just wanted an actual answer to the original question. Like stated about I'm not keeping it.

Yes. Will it idle? Maybe. Can the stock PCM adapt enough to run? Should be able to depending on the cam, but you will probably need to help it along at first. Standard break-in shouldn't exceed 2k rpm for a heat cycle. One cycle is good enough if concerned. If you are varying throttle to build heat in the engine, then AFM/DoD would not be a factor since it takes a low load low rpm condition over time for it to kick in.

If the trailer is to take it to your tuner and dyno of choice, then that tuner will/should also heat cycle the engine prior to and during the tuning process. Only after a good initial tune and some small runs through the rpm range will the tuner take the car through any WOT attempts.
