Magnuson Magnum 2650

I can make you a custom pulley that lowers the boost and makes it even quieter too

 

LOL

 

@snivilous can also make you a much smaller pulley that makes it way louder for a few minutes of nasty burnouts and then makes it way quieter afterwards. Like dead silent…

 

Wait...What?

 

It's disappointingly quiet, even with a smaller pulley

 

He's talking about that Top Fuel maintenance schedule

 

2650 is very quiet and youll barley hear the whine when you mash on it and i have a sniv smaller pulley. now i really cant hear it over the 3" exhaust

 

Barely hear it at "around town" speeds


more acceleration = more noticeable

 

Thanks for all the responses. I definitely wont hear it over my SPD cat back, then

 

One more on it being much quieter, and I think that I'm running the smallest available pulley, FWTW.

 

nope

 

honestly i wish i could hear MORE of the whine lol

 

SPD downpipes here it absolutely drowns any whine even with 76mm pulley.

 

You're not

 

Nice!

 

Dang, that's disappointing...

 

Gads!

 

ive got the 76 also but not down pipes. but i have stick first cats and right after the second O2 its 3" back so all i hear is exhaust

 

Headers with the 2650 here you can hear mine wine on start up and when driving around with the windows up on stock pulley at sea level.

 

Right on! Maggie or harrop? Is the rest of your exhaust setup loud or fairly quiet?

 

Maggie, there is nothing quite about my truck. However, the only time it's actually quite is once it's warm and I am just crusing normally no RPM you can't really hear anything. My trucks pretty loud, sitting at idle you can hear it.

 

sound clips or vid…. cmon man

That was before I did true duel full 3 inch single mufflers not two and its louder

 

I want a smaller pulley but I don't wanna have to swap injectors

 

i have a smaller pulley with kit injectors. but im also at 7k elevation. sniv does make an 80mm now i believe. thats 6mm smaller than stock instead of his normal 10 just food for thought

 

not bad. im full dual 3" from 1st cat back with carven TRs

 

Yeah trucks already running 7psi stock pulley 1600ft elevation. Not sure if it would be worth going to a 80 without swaping injectors. It would be close but I don't think I wanna go anywhere near 12 with stock internals so idk.

Little more boost would be nice

 

WTH would your current electronic dash display of choice be 'Current Fuel Econmy'??

 

It helps keep me awake on long drives

 

I wouldn't be worried about 12 on stock internals unless you drive at full throttle everywhere. I usually tell people the 10-12psi range is where Im comfortable with the truck, and pushing it behind that becomes more questionable. That also tends to be when the MAF and (normal) larger injectors start to max out so you're getting the most bang for your buck out of everything.

My current inventory of pulleys is 81/76/70/65. Not sure how much boost the 81 would give you, probably only one or two psi, but the 76 I know definitely pushed the limit at lower elevation though some people on here have done it before convincing themselves to bump injector.
