Quick question

Do our trucks need to be warmed up to create their max boost?

If youf truck normally makes about 23 PSI when it is warmed up and running good, would i be able to go out to my truck with a cold motor, start it and then get on it, would it create the 23 PSI or would the motor need to be warmed up first?

Not sure i explained that right, may need to edit...

Thanks!

do you mean can you jump in your truck start it up then just drive at WOT?

it will create max boost but its not good on your truck.

No. They don't HAVE to be, but its not a good idea.

OK, yeah i know it not a good idea but was just curious.

Installed a riffraff billet wheel last night and then took it around the block real fast once it was back together. I didnt see any gains in boost so i wasnt sure if the truck needed to be at operating temp to produce it max boost output or not. It di spool faster and seem to hold teh power through the RPM's longer so that is good. But i no longer have a whistle

It had the Borgwarner whistlin wheel on it that i replaced. That thing whistled like a 6.0.

Will take it for a better test drive later once i get home from work and let it warm up properly this time.

Thanks.

Some of the wheels out there people think it will always give you more boost. Not always the case. The increases, if none seen in boost, are flow related. The wheel may be giving you more CFM's giving you the better/longer power band range and less smoke. Flow and pressure, no matter if its air or fluid, is definitely related, but not absolute directly related.

i get around 30 with my riffraff wheel. ive seen 33 before.
i have php tunes, 4 inch ex, and s b intake.

the powerband is much smoother and less smoke.
so i may not see a lot higher boost but i can definitely feel the power difference.

p.s. my riffraff billet wheel makes lots of noise out of the intake.
especially between 10-15 psi its almost annoying.
does your do this?
at first i thought i had a boost leak somewhere but their isnt one cause my boost is high and egts arent high.

went and drove today and held a steady 33 psi from 70-100 mph. egts were only between 1200 and 1300 degrees at 100 mph.

Went home Friday and let the truck warm up completely then took her our for a spin. I currently have a superchips programmer so boost levels wont be as high till I get my Phoenix chip (hopefully this week or next).

In performance mode i was seeing 23 PSI at WOT with the Borgwarner wheel.
Now i am seeing about 26 PSI but the truck defuels and SES light comes on. So i am definitely building more boost as the truck never used to defuel and trip the SES light from over boosting. Power is a lot smoother and seems to pull harder all the way up to 3300 RPM. EGT's seem to be a bit cooler but i still havent really got to play with it much.

My whistle is not loud at all any more. The Borgwarner whistlin wheel was loud but sounded really good, sounded like it had a big turbo in it. I do notice more whistle at lower RPM and lower boost readings but once it spools up its fairly quiet and i can hear the exhaust over the turbo now. But i also have a ATS ported housing so that may have sumthin to do with it.

Cant wait for my chip to get here!

ya mine has a almost annoying whistle down low.
just wait until you go uphill at 10 psi of boost. its extremely loud.
i set the ses light in every setting now, even 65hp tow. but my truck doesnt defuel thanks to my php phoenix.

oh and i made 33 psi of boost on 120 race, havent tested it in 140 extreme yet.
