I remeber this now. So, what's a fare driveline loss assumption for a C3 IRS? 17%? ? This is closer to what I would have "guessed" in the first place. Is it more maybe?
I know the motor I have in my C3 Vette, which pulled a 391 at this event, dynoed 432 in the C5 Vette it came out of. That was with Headers and a much more aggressive tune. Curious to see what I get with Headers and a Tune. . .

I just got off the phone with ATI, I was calling for a pulley recommendation to get me up to 15 lbs. I told him that I'm getting 5 1/2 now with my 4" pulley and he told me that my belt must be slipping a lot. He said that a similar motor made 10-12 lbs with my pulley. He said that the boost should build with rpm, and it doesn't. Mine stays at 5 1/2 from 3K rpm to 6K rpm.
So I'm going to tighten the crap out of the belt and see what happens.

I don't think it's related to your boost issue, but what's the story regarding your vacuum? Are you going to get a pump?

I need to get a better job first. My company has not given me work in weeks. I'm more broke than a GN engine.  Law school apps are $72 on average, I've submit 9 so far. 
I've been thinking about doing a high flow evacuation system using the SC itself.
If I route a larger hose (heater hose size) to the top of the air filter, run that directly to the valve cover, and open up the breather hole and cut out the baffling on the other side (I have stud girdles to control the oil) it might be sufficient. |

Out of curiosity, do you have anybody read them prior to submission? Ah just teasing. . .

Just like 3 people! Haha, I've been accepted to one already. So now I just need to wait and pick the best school that accepts me.
Sean, is it free? If you want to see how fast my car is that bad we can do a run down Crowther. I've got nothing to hide. Just my small penis. |

We need some data entry (production vehicle database.) We'll gladly pay for you and your small penis to have a day at the track (and more) if you want some work.

Adam, I must agree dyno'ing your car and than not running it is for lack of a better term pussy. I SHOULD have my car done by than and if so will absolutely be at the track as well. Neal wants me to check if my car has a broken rocker shaft as he says our initial diagnosis was assumed without much thought to what else it could be but I don't think I have enough tools to rip off the valve cover as I don't think we have deep sockets. I talked to the automatic kings Sean they said it's 220 to restall it  . It's 275 for a bitchin' ass brand new converter so fuck them. I say f the math come out and you can say my car runs XX in the 1/4 cuz that is all that matters anyway when it comes down to it. Jusy my .02, I will say dyno's are useful for tuning though so don't start crawling up my ass...insert joke here.
Brian
