I did my cam and got 411 rwhp. I'm itching to do a Procharger. If that puts me in the 510-530 rwhp, can the internals take it? Do you suspect a short engine life?
Yes the internals can take it, if you stay to max 7psi. But if you will be doing standing launches and what not, I'd be more worried about the tranny......with the hp at 7psi, you are at the max tq the transmission is rated for.
Stock bottom 5.7's are good for about 8 psi, but I really recommend you stay at 7 psi. Your engine will be fine at these levels. The stock A5 tranny is only good for about 550 rwhp. Just curious, you got 411 rwhp with just a cam??
As I understand it from a local performance shop. It's not the boost pressure that cause's problems but air temp that goes into the fuel and into the cylinders. Intercoolers only do half the job. You also need a Meth kit and a secondary air sensor to combat the high heat air before it goes into the cylinder. The ECU needs this info in order to adjust and add more fuel to keep the engine from Pre-detonation. I think I explained this correctly.
If you are using an NA cam you might want to change to a blower cam after the supercharger. An aggressive NA cam won't hurt you and will give better numbers than the stock cam, but you might be leaving a bit of power on the table.
Any time that you force a motor to operate beyond its intended capacity, you will shorten its life. It's only a question of how much.
I had a Whipple installed on my '16 R/T knowing that that would be the case, but I'm good with that. I'm willing to trade a shorter engine life for more fun, and I intend to maintain the motor regularly so I don't expect it to go *that* much sooner.
To answer your question about internals, my motor is stock (including the cam), I'm running eight pounds of boost, and I have 500 rwhp. I'm sure your motor would be fine at 510-530, but if you run more than eight pounds, you're pushing your luck unless you forge the bottom end.
Hi Did you checkout Dings performance, they are a HHP certified shop. They have a dyno and do some amazing tunes. They are located in Vancouver WA. Look at there web site.
Have you had it to the track yet? I'll bet his LL cam retains a healthy bottom end. We only ever talk about peak hp numbers when we mention dynos but Jay is smart about designing his cams to have a wide power band.
A real tune on a real dyno is the only real way to get best performance and safety of a stressed engine.
Data logging is less than optimal and gives false HP/Torque numbers. I can get 50 hp showing with the engine idling and the car coasting down hill on a log.
I did the Stage 2 LL 204/222 Greene Racing Cam. Greene Racing did the tune. Believe it or not I added A throttle body spacer(Airaid) to that original level of build and ended up with 417RWHP, go figure(seems the velocity of air trumps volume, or, I could be wrong-but these are dyno redults, I'll take the extra 6 hp). I recently added a ported 392 Intake Manifold and SOS ignition coils, I'm looking forward to getting the set-up re-dyno'd to see where I'm at. I'm wanting 450'sh. NA was my original goal, but 500NA rwhp is elusive or crazy expensive. That's why I'm considering a Procharger.
