Turbo Nytro #'s

[detz1000]

Why does PL say I have 270hp at 12psi boost but others are running more psi and claiming same hp. What psi should I run at 1000ft on pump gas and at6000 to 9000 ft on pump. Also when I let it warm up the AF #'s bounce around really high but if I touch the throttle they go right to normal its a liquid AEM.

The general rule of thumb is 10hp per lb of boost, however I think 8-9 is more realistic. Why different companies claim different numbers...you might have to ask them. Every dyno out there is different, as is the difference in all the kits.

In theory my boondocker would be putting out 300hp at 17lbs of boost (130 base + 170 in boost), but in reality, I dont think it pulls more than about 270 or so....which is still plenty for me.

Depends on how much air a turbo is moving. You could have a smaller turbo making more boost, but less hp than a bigger turbo. boost numbers are only one part of the HP equation. E-mail Dave at PL about what fuel at what boost level.

detz: Usually when the gauges bounce like that or read lean, the probe is bad.

Thanks alot guys what's the sensor part#. Do you know what kind of boost I can run if I run 50\50 or 100%. Thanks DETZ

Before you buy a new sensor check your current one with the process they outline on you tube with a video. Just search youtube for "checking a AEM sensor" and it will come up.

Also if you have exhaust leak it will bounce around like that at idle. With your glove on put yuor hand over the exhaust it should kill instantly. If not or sputters you have a leak and that will mess with your readings at idle. I thought the fluttering aroudn was normal till I dropped my skid doing some upgrades and noticed my exhaust was cracked. Had it welded up and boom fixed the AEM gauge at idle! yay! Its a two in one gauge tells you AF and when you have a exhaust leaks LOL

Sorry Dude, I really do not like that rule it certainly does not apply to everything and does not work at different boost levels.

Besides some other good point that were made if you’re A/F gauge is reading high numbers at idle and bouncing around it could be lean and the probe might be sniffing some fresh outside air if it is mounted close to the end of the exhaust and the idle is low.
