Thumbs up PFS Tuned T67 dyno #"s

Street port
720/1680
T67 .81 ptrim.

Ray said that it hits 15 then creeps to 16psi. He is going to clean up the drivability stuff and then I should be able to take her home. Can't wait to feel some BOOST in my pants.

Hats off to you Ray and your guys Jason & Jamie. Job well done.

Congrats!! Very nice looking dyno sheet. I just wish it showed RPM instead of time. But still, that is going to be a TON of fun to drive.

I can't view the graph very well. Are those AFRs around 12 at peak horsepower?

Do you have corrected numbers?

The graph is plenty big enough to see the a/f. Ray even told me that it looks like it goes rich when the wastegate opens. You can see that when it peaks at 15/16 the a/f goes to 12.

I dunno man. I just turn wrenches. Ray said something about it getting a false reading but as far as dynos and that. You'd be better off asking Ray.

I'm the excited owner.

Yea Ray.. :p

I asked and he said the turbo was responsive. I think that the smaller .81 Ray suggested is going to make me happy.

Dave, tell me when you bring it home, can't wait to hear it and feel the single turbo!!! And I agree with Brian, you were looking at 400@15psi. You got 430@16. That is just amazing. Did he get a map loaded for you to run on race gas at 18-20psi?

Dave,
Thats some very impressive numbers bro! Must be the manifold...lol... Wait to do the Hooters Meet till we both have our cars back. By the looks at the way it spools, it appears to be a better power curve than the T78 for the street. Good choice!

No it's still up there at the shop. Ray called me on Friday and told me it was done but that he was also leaving town over the weekend. I'll have to get by there either sometime thius week or next weekend. The shop is about two hours from my house though so it's kind of difficult to swing by at the drop of a hat.

Plus I still have the crunched front end to deal with. So even after I get it back in my shop it will be another week or two before I really get a chance to take it out and beat on it some.

Dan, if I can get the body straight before then I would love to come up and chill out some.

Kevin, I will be at the track but most likely not till spring. I just got it back after a year so I don't want to break it just yet. I need at least a trouble free winter to keep my wife off my ***.
