How much boost?

Re: How much boost?

They're just jerking your chain a bit. Do some reading on here - raising the boost without knowing what you are doing is about the fastest way to break expensive things. Learning how to use Datamaster will let you see how your particular truck handles boost - they're all different.

I thought someone ran like 28 or so once or twice?!?!?!

Just that mean once or twice before pieces were left all over the highway? ;)

Well, the truck still runs and will be making the trip to nationals. But we didn't do that overnight and surely didn't use a KB chip, was done with custom tuning.:tup:

come to the nats, we can show everybody first hand. :lol:

I know I saw 28psi on Hardmans truck just before getting out of the gas, and I think I'm the one that caused the ring land to break :(.....Stock bottom end with a PT52, and right foot boost control :( :(....Sorry Mike

In other more thread related info, I still think I've seen someone running 28 on a stock turbo. I can't remember whom it was though. It's super way out of it's effeciency range, but with enough meth and a huge intercooler it's doable

Re: How much boost?

To answer the original posters question with what I believe he was trying to get at:

Typically 14-16 PSI on 93 octane pump gas. I could barely do 14 PSI on my truck with no knock, but I have heard of others who were lucky enough to run 16 PSI without detonation.

If you add a high octane mixture via alcohol injection or race fuel, that's another topic altogether.

Re: How much boost?

I can get 18psi on 94-95 oct. and only se 2* of KR. on 100oct its all but gone except a few deg. at shift changes. But thats after playing a lot with my truck and I have a few mods. DM is a must and you should get one before any mod is done. IMO.
