how much boost can a whipple put out??

 

Ive heard up to 16-17psi....

but.... some people will disagree..

I was running 11-12psi and had 2 more pullies to go!!

 

how were you running so much boost? That's odd. The smallest pulley will only get you 10ish. hmmm.

 

I have no idea....

We were suprised.. I mean the boost gauge coulda been reading Inaccuratly..

But Justin (yellowsierra) have a I guess 2.75 or somewhere around there pulley made and he was running ?13-14? on his 5.7.. So I was guessing around 15-17 on a 5.3 or 4.8

 

Boost isn't an accurate meaure of maxing out a blower or making power. Boost is restriction. I could make 15psi with a whipple on a 4.8 if it had tiny heads, valves, stock manifolds and exhaust. Will that make more power than a whipple (with the same pulley), nice flowing heads and exhaust, and a properly spec'd cam. No, and the latter setup will result in less boost.

If you're concerned about maxing out your whipple then step up to the 3300AX.

 

well i was wondering becasue i'm about to put some 6.0 heads on my 5.3 and i was told to run about 15psi and i was wondering if the blowwer could handle it

 

Definently..... You will probably have to get the pulley made for that..

Contact "Ironworker" he bought my whipple from me.... He has a pulley that Yellowsierra had made.... It should be good for that!!

 

whipple's are only made for 16k rpm....at 12 lbs of boost you actually making all the boost you can. A buddy of mine and fellow ls1tech'r ranwalk is maxing out his whipple making 21k rpm....thats w/ a custom pulley so yes you can max out a whipple

 

how much boost is 21k rpm

 

And if he had to make a pulley to do that, did he make an even smaller one that did not increase the boost? How do you know he was maxing it out?
