Re: Why are these holes made in crankshafts?

There have been some epic discussions about this. I purchased a surplus text from the Library of Congress that contained the original published research from 1930s Germany wherein various crankshaft designs and materials were tested. It is the original work that was translated by the US Government ...

Re: Indy car engine difference…

Again, you have no idea, and you seem to ignore the facts. Anyone that knows anything about engines, knows a 22% increase in CID doesn't make up for a 35% reduction in RPM. Anyone knows that the stock block V6 needed an increase in boost to be competitive. CART made sure it never was competitive. CA...

Re: Indy car engine difference…

Cart didn't limit engines or chassis, they just had to comply with the Formula of the rules. There were many chassis and engines competed, under CART. Remember the Buick? Again, you have no idea what you're talking about. The Buick Was a 2-Valve, pushrod, stock block engine, that required increased...

Re: Indy car engine difference…

You can blame Tony George, for what has happened to it!!! Had CART kept control, it could today, have rivaled F1. You have no idea what you're talking about. Tony George tried to save IndyCar, but was too late. CART was killing IndyCar. They were headed right down the path, to what we have now. CAR...

Re: Indy car engine difference…

Completely different engines. The engines are homologated, and every part must be approved by IndyCar. IndyCar controls the HP output, to keep the engines even. No team can work on their engines. Engines are sealed. After an engine is approved the manufacturer can not make any component changes, wit...

Re: Assumption: Valve train deflection increases with lift & higher spring load

Yah but after the load is removed and lift is on the decline right? We're not talking like a slick sidewall storing and returning energy. Peak lift is still lost even if duration is lofted. Not saying if that is good or bad just saying that's how I understand pushrod deflection. Nope. The pushrods ...

Re: COMP Cams LST solid roller lobes... "Top Secret"?

Comp makes their money, by selling marginal cams to people who believe their marketing BS, and people who think those top running race cars with Comp's decals on them, are actually running Comp Cams. Back when Scott Bloomquist was winning everything in Dirt Latemodels, He was being Paid to run Comp'...

Re: COMP Cams LST solid roller lobes... "Top Secret"?

They're not going to tell you what they're doing, because they're doing what we were doing in 1979, but to a lesser degree, because they're grinding with 18-22" grinding wheels, not 5" wheels, like we use. They will go out of their way, to avoid using the term "Inverse Radius", because they spent th...

Re: How is the camshaft supply today.

I recently made an inquiry to a certain camshaft company about what UGL blanks were available for grinding a custom big block Ford roller camshaft ... being that it is not all that popular and they might actually have something. The ONLY roller UGL they had for a big block Ford was for a .460" to ....

Re: How is the camshaft supply today.

I'm just wondering how the camshaft and lifter supply is doing. It's crazy. I only deal with U.S. suppliers, so I don't know how the import inventory is doing. There's 3 major Cam Core suppliers in the US. All their manufacturing facilities were closed down for 6+ months, and all are having issues,...

I recommend a high volume pump, but not required.
Yes, the cam will work with 1.6 rockers

Re: Open or Crate?

The open motor can make a lot more HP, then the crate, but where the crate will sometimes out-perform the open engines, is on restarts. Some tracks will allow the leader to drop the rpm's way down for the restart, and that will give the advantage to the crates. Since the open engine has to run cast ...

Re: Open or Crate?

Do they allow any chassis/tire modifications for the 602 crate? (larger spoiler, less weight, better tire, etc)
