I am looking to add a blower to my 2015 5.3 but the one thing I don't want to deal with is noise at cruise. I don't care how loud anything is at WOT but I don't want to hear a blower at cruise ( silent at idle would be nice also ). I had big plans for a full exhaust and headers on this thing before I bought it and now that ive driven some long highway miles in it, I actually really dig how silent it is.

My first choice was the procharger P1 set up, but the more I look at the gains and dyno graph on the whipple 2.9, the more tempting that becomes. Can anyone provide feedback on either of these while cruising down the road? Either or both of them noticeable over stock exhaust noise levels at freeway cruise speeds?

Also a major concern is quality of the tune provided for each unit. Obviously they are safe tunes on the motor side of things; how is transmission performance? Not sure there is anyone local that can dig in to my tune.

Any other feedback on either system is appreciated as well. I realize that the power delivery of the 2 systems is completely different. The main goal is just a bump in power in general, while maintaining factory ( audible )comfort levels. The sleeper factor comes in here a bit as well, another reason the stock exhaust is staying on. I can already get a nice jump on the oil burners from a dig but id love to rope in some poor sucker with a 5" exhaust and a programmer at every light I can for a good old fashion *** kicking...

Also, price is not a deciding factor here. Any of the systems fall into my price range.
Not interested in turbo systems for this rig either. Huge turbo fan, just not on this rig.

And last, can I spray meth through a whipplecharger? I would really like to get a meth kit on this thing sooner rather than later just to deal with the crap building up on the valves.

 

Magnacharger has the bypass valve that prevents it from building boost under light loads. You wont hear a thing most of the time.

Also 2014+ are direct injection it's burns incredibly efficient. Do don't be concerned with carbon build up on the valves.

 

Direct injection is actually the whole reason why there is carbon build up on valves. No fuel washing things off as it heads through the runner past the valve

 

Exactly.

 

Well that's contrary to what I've experienced in all the diesels I've torn apart. I'd be interested to see some gasoline DI heads with some miles on them.

We'll I have found quite a bit of evidence that DI gas engines are having carbon issues. That's not what I would have expected. The LT series is very new yet hope that they are cleaner than ecoboosts.

 

Interesting, I see plenty of diesels with intake systems slugged with carbon at rebuild time. These are larger marine diesels though, might be different sized stuff than what youre talking about? Though its never too much build up on valves, I can take chunks of it out of intake runners.

Anyhow, BMW has had a hell of a time with carbon and fords ecobust motors are catching up now that they are starting to get some serious miles on them.

 

can you hear your blower at cruise?

 

I've done about a dozen powerstrokes and 30 Cummins. As long as the egr is gone they are usually pretty clean.

 

Before I had long tubes and 3 inch duals I could only hear my blower at WOT. At cruising speed or light acceleration you would never know. That's with a magnuson MP112. After adding all the exhaust and can't hear anything but exhaust screaming.

 

I have a tvs1900 and you only barely hear that at wot.

Best mod to date for a stock crew cab on corn.
