Jim's cv1 head is a very sound design in theory, he has stepped out of the box on design and the base of it is right on. However there are certain things about it that is obviously catering to the market for him to be able to have a sellable piece. And consequently these are the same things that are phucking it up for being are good race head. The biggest hurdle for the Pontiac racer is the Pontiac racers.

And if you think that I'm not a part of the community trying to drive the Pontiac engine forward you're crazy or stupid.

... i agree 1000% John !!! ...

2. no one is paying him to do it.....or he would. If I took him cv-1s and a bankroll and we designed a whole engine around it, It would be bad azz.....that been the issue the whole time no one wants to do it.

Has anyone gone 180 MPH at 3180 lbs on NOS with a Pontiac?

Who are these few?

... good point, i can't wait until we can answer that question ...

... but something else i would really like to see, if for just once, one of these threads can actually turn into a hardcore, genuine Q&A session, where people are not trying to push one head in front of the other, with enough time the heads will show that ...

... i'm talking about guys at the high end of the RPM game are actually in the position to answer questions, or maybe even ask a couple, in a thread where there is no BS comments or hatred towards each other, a truely open format, where there is no stupid question, and it's answered as such, it goes a really long way to show respect to others, and that alone can really boost someone's interest or even ability to understand new information ...

... hell, some of the meanest MF's in the world in the UFC beat the snot out of each other, and at the end of the match, they get up and shake hands etc ...

... we can do better ... if you guys want to push this market forward, it starts with discussion like i just described, because i can promise all of you one thing, any engine does not care what color you paint it, what decal is on the hood, or what you THINK it should do, 100% of the time and ALWAYS, the engine is right, not us ...

Lol, i didn't mean Dick or the people involved shouldn't care, i meant i don't care i bet others don't as well since the car will never run without nitrous it will never back up the NA power on that dyno sheet with a time slip.

... not in a dedicated N20 car, certainly not, but that's kinda my point ...

... those type of comments read like a N20 car really doesn't rely on how much power the engine makes on it's own, which is well, not correct ... that's all i meant

And mine as well, lol. So why bring it up??

... very simple, because what the engine makes N/A will effect what it runs on N20, that's why ... the way that reads is N/A power makes no difference what the car runs on N20, which is totally false ...

... got it ??? ...

I will be hanging out.
I am after Very High Velocity Heads like my 1970 RAIV's.
In the Future .
Perhaps late Summer
I could give a Fick Less about Peak Air Flow numbers..
Average under the Curve.
E/I ratio.
Must Be 100 % dependable.

Run Time 9-seconds to 2 minutes Wide Open Throttle .

Zero Failures.
Street Racing at at night.
Combinations of Drag Racing & Endurance Racing.

[wheneaglesfly]

8,000-9,000 RPM Peak.

6200-7000 Rpm will beat 97-99 % of all.

High velocity heads at what valve lift? What does high velocity mean? Smaller ports have higher air speed, to the point they can no longer move enough air because the air speed is so fast it chokes.

Engine size and RPM, and HP goals are needed.

Thanks you for touching on that point. Velocity is dependent on the flow coefficient of the cross-sectional area and pressure differential on the runner. Small or big ports only tell a portion of the story . Many people think they're going left but are actually going to the right on this subject.

... exactly, velocity is simply a result of other very important factors, most people would be very surprised to hear certain engines have had the airflow and velocity reduced in the intake port and made more power... it begins to mess with the brain a little ...

The flow bench is just a test device. The head will see a much different velocity on the engine @ wot @ peak power and this is the one that counts.

But the good porters can correlate this data to what works and doesn't work on the strip.
