[Fot] SVRA & belts and HANS

[Bill Babcock]

Been there, done that Mike. I dropped what was left of my trans and bellhousing onto the front straight at Pacific Raceways just before the turn—maxed out in top gear. Probably wasn’t a failure to properly torque the studs. I think the studs just don’t like that sustained vibration at 6800 RPM. The flywheel had four ARP studs and two dowels. I’ve gone to eight ARP studs.

SCCA changed from the 2 year rule on belts to 5 years after sufficient proof that the webbing wasnt setting outside in the elements 24/7, which was the excuse manufacturers used for pushing the 2 year rule.  Havent been to an SVRA event in over a decade but will be going to Mid-O next month with my FV.

I got mine re-cert for the Mid-O trip.  Cost a lot more than $65 including shipping two ways and I think the fee was more like $75 or so.

Lucky me, just bought a set of Speedsters and planning on getting a driving lesson from Snook but at the J500 the flywheel unbolted itself and in the process caused the trans case to actually get sheared in half at about the fill plug.  Presumably due to the torque shock since it gave up the flywheel at WOT in 4th gear.  Guess who last had a chance to incorrectly torque said flywheel?  Yep me.  Those unused speedsters may end up for sale.

Since I just stopped using the bias ply Hoosier Vintage TDs last year (after 19 years!), I’m hardly one to comment on the more modern radials.  I went with the Speedster 185/65-15 for mainly fit and appearance reasons.  Got to say I love them, but it takes a different driving style that I am still getting used to after 19 years of tossing the old TR3 around on bias ply tires.  I am concerned however about the extra stresses and strains these stickier radials are putting on the chassis.  What is the next thing that is going to break?!  How about we all agree to race on bias ply Dunlops?  That way we would all be on the same playing field, and those Dunlops last forever!

I just purchased some new belts for my Lotus and went with the FIA that had the 5 year expiration.  Cost another $100 from Simpson, but worth it if the SFIs are only good for 2 years!  Also checked the fire system bottle in the Lotus.  It was 20+ years old and filled with Halon.  Pegasus had an interchangeable bottle with the new stuff, so I ordered one.  Surprised when it arrived with only a 2 year certification, needs to be re-certified every 2 years!!
