Must have the stock parts back in place then. Glad to see your mood has drasticly changed.

Glad to hear you in a better mood today Shumby, will be interested in how the test pipes respond.

I'm willing to bet Stillen will run into the same issue if they attempt to tune their kit with LTH's and CBE pre-installed.

Maybe some catted LTH's would allow for some backpressure build up and thus retain pressure in the chamber? I guess someone will need to test this out and see if any gains are made versus stock headers and test pipes combo.
Only if the values are not fixed according to load and it has some sort of advance/retard look-up tables it can follow to vary according to other conditions (i.e., similar to the ignition and fueling maps)... however, maps for valve timing are usually fixed and only vary by load.

As awesome as these results are going to be it's still sad that we're restricted due to excessive exhaust flow. This may lead a few people to invest in built super high revving N/A setups and later go with a supercharger or maybe more TT because if you are going to invest that much into a car you don't want to hear about being limited to stock components. Personally I think if anyone can do it, its Smokey and Top Secret.

So far the only thing you cant do is LTHs so thats not really limiting anything or very little and if somone goes TT just because of that they deserve to pay the extra 6K.

it's not the LTH IMO. I mean for the guys with G35 HR's and 350Z HR's wanting to run the LTH's with the SC setup then that shouldn't be a problem.

I agree I am doing more research on the issue. But my inital thought is the exhaust valves are opening too soon or staying open too late (basically while the intake valves are open. So a lot of the pressure the supercharger is making is going to waste. By advancing or retarding the cams you should be able to build more cylinder pressure possibly. But I need to do some more research.

This is a little more off the wall thought and I don't know if y'alls computers are even capable of this but, if your not getting enough fuel will the computer adjust the valves in order to maintain the as close to the proper a/f ratio as possible. In other words it releases air until it can get a small enough amount with the fuel it's providing.

I know I read an article talking about how technically your engines don't even need throttle bodies because of the vvel so vvel might be able to do a ton more than we currently think.

Again these are thoughts and could be totally off base but might lead to the right direction. A good place to look would be to look at the duty cycles of the pumps and injectors and see if they are within reasonable limits.

The TB's on the 3.7 stay open at 100% I believe. The VVEL actuator basically allows the valves to function like a TB by increasing/decreasing lift and duration, only using the valves and the eccentric cams rather than the actual TB's. Anyhow, until we can get control over VVEL, LTH's are a no no with SC setups I guess. Hence why I said LTH would most likely not be an issue with HR's since cam timing can be altered using Uprev, unlike the VHR. I guess we'll just have to wait and see till more testing is done. Thing is, even if Uprev does allow control over VVEL timing, I personally don't trust any Pro Tuner to be able to properly adjust it. good thing I have an HR G35 I guess lol.
