Factory experimental

[Fred Holdorf]

Rory, Yes there were supercharged Ford's and Studebaker's in "Stock" many years ago. Larry Walker and myself at one time had to make a full pass, with a tech inspector riding along monitoring his own calibrated boost pressure gauge. We, (1957 Ford) were allowed 6# of boost @ 4800 RPM's, plus 1# of boost for every 1000 RPM's over 4800 RPM's we turned the engine. I understand Gordon Williams had to do the same with his Studebaker also. Has anything like that been done lately, or are there any boost specs on these new cars at all. Any body know?

How much HP does a 426 Hemi or 427 Chevy stocker motor make?

A good Street Hemi should make somewhere in the neighborhood of 650 HP. Don't know about the 427's.

Where were you guys about 6 months ago, when I was beating the drum for tell-tale boost gauges on all forced induction cars because of their inordinate showing as #1 qualifiers at National events??? In the last four years, (had stats for 2004-2007 at the time) about two percent of the cars (turbo cars) had nailed down something like fifteen-percent of the #1 qualifying slots... a statistical anomaly that screams for attention.

Now that the issue is a different one, but the cause of the problem is the same, you come out with this.

Since horsepower at the flywheel is almost certainly boost-dependent, OF COURSE it needs to be monitored to factory specs, one way or another. Tell-tale boost gauges is one effective way to do it.

I still think these "new" factory race cars belong in S/S.... especially, the ones with less than 7.5 lbs/hp.



How about when a turbo car at a alt. track sets a record 1.58 under but wait, it can't get hit because it's a alt track. Sorry almost a year later that still bothers me.
