The ZEX kit is activated by TPS, meaning it is turned on in relationship to throttle opening. In our case it is approximately 75% throttle opening.
Will the rear hold up with the mickey e.t. radials,.... Don't know, The car has gone 1.70 60ft without a peep. But now we plan on hitting it a little harder. The axles are not an issue, I have plenty of faith in the Moser pieces, it's just the small ring gear that has my concerns. I can tell you that we have an 8.8 from an 05 GT in staging.
How long will the motor last? At this power level I am unsure, I see no reason why it would have a problem, fortunatly for me I have a background in Turbo Buicks, I have seen some pretty amazing things come from a GM 3.8 with a cast crank, stock rods and cast pistons. Mid 10's hauling 3600pounds was not uncommon.
But the 4.0 is a bit different. But is any less strong?
I'll tell you this, I admire you giving the stock rearend a chance, allthough heavily upgraded with T-LOK(Still using 7.5-upgraded with T-LOK).. The most important work PowerHouse can do, is find the limits of our stock factory components... This is crucial..
Now granted I'm not advising you to burn up the 4.0.. But if you come to us and say, "You know guys, the best you can hope for is 425RWHP out of your motor before things start to break" , that will be acceptable.. LOL!!
Seriously, pwrhws's willingness to take his time on upgrading certain components is awsome... This way, he can tell us later, not to worry about certain pieces, thus saving us money later.. We can just shoot for the essentials, and head to the track!
Also, its nice to hear the detonation on the Zex system is based on throttle response.. Thats better than I had hoped for..
So for the record, the dyno info submitted earlier consist of an all Factory 4.0 motor making over 400 RWTQ at launch and leveling out at 300RWHP, and 300RWTQ at 5500?
I ask this question so V6 owners viewing this understand the impact of the work you have done.. This means, that pwrhws's engine, less the Zex kit and jetting is exactly the same as ours.. At this point he has not done any engine upgrades...
I am alittle in-different to people implying it wont hold up, or for how long.. But I guess this is part of the reality.. But lets say something does break.. Even in a 4.6, things will break for whatever reason.. So why attribute something that could happen, to the engines tolerances until more than one suffers from the same component failure with a given set of circustances? It does not seem fair I dont think.. Basically, I am accepting on face value pwrhws's work which states our motors are good for a 439 RWTQ Launch, and a promise of 300RWHP, and 300RWTQ at 5500RPM.. Thats it.. No speculation on how long it will last, thats ridiculous..
lol.
haha. im thumbin through all my timeslips.... man these 60ft times are bad (1 is almsot 2.9!!)
