572 World Aluminum close to Dyno

[biomedtechguy]

Similar looking shape to the curves from what I can tell. Looks like the 572 has more torque gain than HP gain up to about 5600, (I will see if you posted lower RPM TQ and HP data) torque seems to fall at a little steeper rate w/the 572 above 6600...
My inexperienced .02..
I'm really curious what the dip in HP and TQ is at 6600 w/the 572?

Disregard the dip I imagined. Now that I see the #s I can see the HP/TQ output.
Very nice.

I just got off the phone with the race fuel supplier here in Canada, and I’m wishing now that I built a pump gas motor. Man fuel has gotten expensive.

Everything else has as well!

Not good Wooks, better grab a barrel though cause it will only go up before it comes back down. We talked about that several times last year but you already had pistons, hard to change course at that point.

Boy am I glad I bought a barrel of Renegade 114 last year. It was like $650

572 is now in the car and running. It went very smooth. I must of done something wrong? LOL.

Wooks, could you convert to E85, or methanol? I don't know what fuel availability you have?
Not bragging, just admitting I am cheap. And since I'm not trying to be the fastest guy on the block, I'm never gonna build a non-pump gas engine. $7 pump premium (in california) is bad enough!

Can’t wait to hear some track reports!!

Wishing you great results and...

Should be interesting to see what your dial will be this year Wooks being that we’re both limited to 10.00.
Come live on the edge with me and dial 10.00!

What limits you both to 10.00? Just a rollbar?
I can relate: low 10s is a nice place to be. I don't want all the other stuff that goes with nines, even though my car is legal, and can run 9s, I cant.

Yes we are both roll bar. There are a number of fellows that say the same as you 33. Several that race alongside Wooks and I in fact. Buddy Wooks has a tiger by the tail now though. He’s done built one fine wedge!

Dyno box is 4 degrees off from mine. They use a 2 box and mine is a 3.
Not building vacuum. Need to pull my pump apart I guess. Same pump that was on the 511 and it was making good vacuum on it.
It was low on the dyno but I figured it may be their gauge because it was working well on the 511. Also the crankcase would hold pressure, so it should be sealed well?
Open to suggestions.

 

[RemCharger]

It'll all show up in the points.

 

[oldkimmer]

Good luck buddy. Don’t choke it off, let er rip. Kim

 

[Wookie316]

See how it runs through a full 3” system.

 

[33 IMP]

Wookie that is an absolutely beautiful exhaust system! But I'll bet it's a Loud mfer with those Itty bitty mufflers, and 572. lol.

 

[Wookie316]

Yes my welder buddy really fit it in there nice. It is pieces of a TTI and Summit system fit together. Magna Flow race mufflers with dynamax race bullets behind the tip to take the snap out of it. I am amazed at how quite it turned out. Neighborhood will be at peace!

 

[PRHeads]

Be interesting to see what kind of ET difference there is with it all closed up vs the cut-outs open.

What was the vacuum issue?
