Is every one on the east and west coast [sea level] getting full boost ? 8 lb's stock Vortech....9lb's with 9lb pulley.......Im not sure on my elevation...Omaha Ne. but I can get only 7.6 on the 9lb pulley . Im wondering what every one else is getting and the elevation of were you live . Maybe this is the reason .Could every one that reads this with a Vortech post there max boost and elevation . Or does it even matter where you live ? Or can there be another reason ?

 

All things being equal, a turbo or SC will boost slightly more as elevation increases. A lot of guys with TT's have learning boost controllers, that will automatically compensation for elevation, ambient temp, etc, so they'll achieve constant boost regardless of load, elevation, etc.

 

DAM..I thought it was less boost at elevation .Less air with more elevation . I know dam well you going to get less power at elevation

 

I think its the opposite. Since the air is thinner, the turbos spool faster and will generate more manifold pressure. That is my understanding of it.

Squill is the resident turbo expert...and I am sure will chime in and correct me.

 

i am on the east coast, with the stock vortech pulley im getting 7.5 @ 6600, the 9lber is on the way, ill let you know when i get it on.

 

 

Less boost as you go up in altitude. That's why guys in the Rocky's may see 2-3 pounds less. We get a complaint, but we test just about sea level. Other factors are belt slippage, each motor is different, etc.

 

yeppers...


the higher elevations have lessened performance all the way around.....

perhaps, in part, why i was getting 8lbs (on the oem kit), and good numbers?? moreso, the tuner is the culprit... i am 99.9% sure of it.... i spent a fortune (comparitively) on tuning, and know that its the only way i got to the numbers i have now....

as for the 9lb pulley, boog... i KNOW the belts we have stink... the gates are too dand thick, and stretch on full spin. wqe need the gatorback (slashcut) belts, as they retain shape/size much better....

i saw over 30rwhp in belt slippage w/ the gates belt installed... i was freaked out at first!!

im making another change soon, and when i do i will be getting only goodyear belts.....

 

Well thats what I thought .I knew for sure you made less power at elevation and thought it would be less boost also . I will put the GoodYear belt back on , But I dont think the boost will change . Got another Dyno time this week and I will find out....wanted to check A/F again after I got my SS box settings right and finished the timing . Going to diff. dyno [portable] Mustang . Going to see if I can get under the car to check BOV at WOT to see if its leaking by
