i set mine for wastegate pressure to save gas... so 11psi


sike

 

It can spike that high but it tapers down. The stock becomes inefficient with that much boost. That's why you go aftermarket.

I hit about 30 and it tapers to 24

 

I would think that stock turbo will not be running very efficiently at 34 psi. Probably just heating the air. I wonder what his intake temps are at 34 psi.

 

Stock turbo usually starts blowing hot air after 25psi without meth. I hold 24psi all the way to 7k tuned with mods listed.

 

21 holding at 19

 

thanks alot guys how much PSI can the stock bov hold before needing a upgrade

 

peak at 24 drops holds 23. look at the sig.

 

if u running 34 pounds on stock turbo ur nutz. bye bye to motor! and turbo i wouldnt even do that with meth on stock turbo. most is 28 to 30 on meth

 

the stocker should be good for 35psi, im not saying that this is the best for it or even how long it will hold up but it can do it. and i dont know how efficient it is at this point. but i seen a stocker do 35 and 40 with an aem ems. its on youtube if you do a search. the guys racing mustangs and vettes and a 350 w/turbo kit i believe. i believe the efficiency it good up to 30psi or something like that. i have my blitz sbc-id set at 100% and the gain set at 100%, thats why its spikes to 34.5, and once it hits that, it will drop off to between 29-31psi. just curious as why you think the motors gonna blow??????

 

22psi w/ an intake, cat back, IX DV, IX fuel pump, MBC, & tune.

 

I taper at 23psi on 91 octane with a stage 1 tuned.

 

you can probably spike up to 28 lbs or to, tough to say what people hold without logs

 

20psi stock 93 oct

 

im boostin at 21 lbs. on 93 octane

 

How much boost can a stock engine handle with arp head studs?
