Time to go Stage II!

So with that be said, there is no evidence the int. valve is a detriment.

If you are looking for meaningful evidence, you should be asking the many popular engine builders that have installed heads with those size valves, or smaller, for that matter. Maybe some of those engine builders have some engine dyno numbers.
I'm simply one example that others are free to compare against.

I was asking you.

 

[Alky V6]

I was asking you.

If you're asking if I personally have any evidence of what the goals of others were, or are, other than the few people in the San Diego area that I know tried to go as fast as they possibly could with their car, with more heads, then of course I'd have to say no.

No. Im not asking that at all.

Tell you what. Take the time to spell out your question very, very carefully and I'll try to answer it to the best of my ability. Fair enough?

Tell you what, go back over and read the posts very carefully. I've already stated what the question was. I think you have added so much other material to it you have gotten lost.

I guess so. Sorry I couldn't come up with an answer for you. Good luck getting your answer.

Hey, lazaris. What do you figure is a good drivetrain loss percentage to use for our cars. TH400 trans, 12 bolt.

With or without torque converter slip % ?

 

[Alky V6]

With or without torque converter slip % ?

Pick a general slip percentage. Nothing unordinarily tight.

I would say 15-22%

 

[Alky V6]

I would say 15-22%

What is it that pushes it from 15 to 22 for you?

 

[norbs]

What is it that pushes it from 15 to 22 for you?

Number of fins/angles in the torque converter..........

 

[Alky V6]

So most of that variance is due to the torque converter only?

I think those online calculators are full of brown matter. There's no way I was putting out that kind of flywheel horsepower. 1,211 - 1,321? Com'on. And only 30 lbs of boost? BS!

We finally agree !!!!!! yes you didnt make that power

 

[Alky V6]

I know!!! These simpler calculators are whacked! And on a bad tuneup too?! BS!
Maybe it's just the calculator I used. There's something whacked in that equation. I used the one on hotrodpitstop.com. Has anyone else found that one to give stupid results?

Who are you asking? If you're asking me, I personally don't consider any combination that works, and meets or surpasses the goals of the creator to be a "mismatch". I'm much more open minded about other peoples combinations than most, I guess.

You don't remember me ever telling you that I thought you were running heads that had so much more potential than what you were doing with them? I know you have to remember us discussing intake durations and their relationship to the powerband range, and how I thought you were shorting those heads of their full potential. I think I've brought that up a few times over the years.
Kean, you need to read this thread more carefully. I never stated that S2 heads would not turn my engine and the bitchin combination that I'd put together for the heads into a complete monster that would force me to change over to a tube chassis to take full advantage of the vast amount of power I would then have at my fingertips. Oooh. Gives me chills. What I'm saying is that running S2 heads with 215 degrees duration at .050" will not yield impressive track results when compared to a setup that is taking full advantage of a Stage I style head. Surely a S2 head would be streetable with a duration number like that. How can any head not be streetable with such a small duration number. I'm saying, it simply would not be a good representation of the full potential of the Stage II head.
Stage II heads have an exceptional history associated with them, and a reputation to keep. It saddens me to see them dumbed down for street use.

Yes. I remember that well. If I remember right, that person was giving me a lot of grief so I returned the favor. I don't think anyone could blame me for that.

edit: My mistake. I thought that was a different responce that I had made to someone else.
I can honestly say, that is the one post I regret making the most. I should have had the sense to keep my feelings on that subject to myself. I am sorry if I hurt any feelings when I made that post, but I'm especially sorry for hurting my friend Kean's feelings. I don't know what I was thinking.
I firmly believe that when you hurt someone's feelings in such a public way, you should also apologize in a public way.
I'm Sorry, Kean.
