Re: The "4.9 liter turbocharger, stage 1" thread.

Shit I was hoping to get an accurate number from you. I don't know if you realize/understand how important a compressor map is? I am trying to figure out as accurate as possible the choke/surge line for this turbo on a different motor than intended. Sure it's been done on on the 4.9 motor but to my knowledge wasn't intended for this motor correct?

An ill suited turbo can choke at low rpm and surge at high rpm, I am trying to avoid this for both of our sakes and find a happy medium where the turbo operates most efficiently based on the fact that we're both running two entirely different motors than intended.

I know that it has been done on that Fiero, but I don't see any type of A/F ratio or dyno slips posted a long with it. All I see is one mediocre 12 second 1/4 mile time and subsiquent selling of the motor or a plan to "remove it and put it in storage"

In essense, this really does or says nothing in terms of reliability. All it says is that this guy bolted one on and pushed the peddle on the right to the ground. It says nothing about whether or not it can/will last or that it was done correctly, or that the 12 second run can be replicated.

Shit, I've posted a 12 second run with half the pistons and half the turbo.

What I'm saying is that although this has been done, it doesn't seem to have done correctly, only bolted on and that is easy to do.

Replicating an insanely high dyno or a sub 10 second quarter mile more than once is not, which I'm sure isn't your intention, mine either.
