Hey thats fine, ask after you talk to them about the 4th gens..... Just make sure you ask...

 

I don't think it is fair to compare a factory turbocharged car to adding a supercharger to an engine that was not intended for forced induction.

I just read that the 2009 Challenger is running 7.5 -8.5 PSI after tuning with a Diablosport. I guess 8 PSI is possible.

 

For 5K, I would add ported heads, a cam, a tuner, and a full exhaust and could probably get close to the superchargers output.

If done right, the dealer may not notice the above parts either...

 

I'd rather have them tell me up front that a repair wouldn't be covered under warranty than have them tear into an engine and find the non-OEM parts. Then your stuck with the labor that it took to tear it down. Your theroy works as long as any engine damage done doesn't require a tear down.

With the S/C you do have the option of taking it off and making look stock again before taking it in. It would take time but wouldn't be as much trouble as pulling heads and cam.

And no I'm not recommending that anyone try to pull a fast one on the dealerships. Chances are they will find it.

 

I know I can pull heads off fairly easily. Cam, not so much.

I wouldn't do it either, I was just saying.

 

I've never pulled or even read about pulling one out of these Hemi engines. I have pulled it from my 302 when I went with a 347. It wasn't too bad but it was on a stand. I've seen people pull them while still in the car though. It looks like these trucks may have enough room once the rad and stuff is removed. Anyone know if these lifters can be "locked" in the up position like the LS1 motors?

 

...ummm .....the Dodge SRT-4 shared the same 2.4L powerplant as the naturally aspirated Stratus and other cars using the 2.4L in the US and Mexico. Mitsubishi designed the turbo system and the tranny was a turbo diesel plant used in european vans. Anything is possible.........and as a reminder the Vortech guys run the Challenger Diablosport set-up at around 8psi safely.....it can go higher. Todays engines are MUCH stronger than 20 years ago as the technology in materials has changed drastically. Head Gaskets are now multi-layer styles and Head, Rod and Main bolts are stronger thanks to the stronger steel processes.

I need to find out what the current pistons, rods and rod bolts are made of if possible. Anyone know off hand?

 

....possibly true with a reallyyyy aggressive port, cams and tune.....but then again I'll be the guy with this stuff AND and supercharger attached...for another burst of kick ya butt....lol.

Looking back at all the work I did on my last two cars...i'll prolly do it all again.

 

What's the latest news, are they going to make the kit?

 

No, the 2.4L was not shared. The turbo version had a 8.1:1 compression motor while the non turbo version was 10.5:1(?).

Strength is usually not the reason turbo motors blow up, it is usually a detonation/knock issue.

Pistons are cast aluminum, rods are powdered metal, and rod bolts are ?? That is from the service manual.
