CRX flywheel explodes, Carnage ensues.

CRX flywheel explodes, Carnage ensues.

I remember a conversation I had with my father-in-law many years ago about SFI ratings. The topic came up because I was putting a 7lb flywheel in my car, and happened to notice the sticker strongly affixed to the flywheel and the corresponding clutch stating the parts were SFI certified. I wasn’t very familiar with what that meant at the time, and the explanation was that it is a rating and standardization body that supports the automotive industry, and a company who pays particular attention to racing parts.

The story I got was : “Back in the old days, flywheel explosions were common and fire suits and other safety gear were not. The SFI came along and changed all that by inspecting manufacturing processes and materials used to produce performance parts and safety clothing. In other words, the sticker is a good thing.”

As I got more involved in vehicle performance, I became acutely aware of SFI ratings on certain parts, but one thing still stuck in the back of my mind: “Flywheel explosion?! that must be a hell of a sight.”

I have never experienced a flywheel explosion before, but what I found on Honda-Tech.com the other day changed all that. Here is the video:

The following is what is left after a flywheel explodes in a 1991 Honda CRX, in pictures:

As you can see from the wreckage, this is a spectacular display of the potential energy stored in a flywheel. The bell housing of the transmission is totally gone, as is the flywheel housing on the engine side. Motor mounts were broken in half, and the radiator, intercooler, clutch pressure plate and clutch disc are completely destroyed.

Some speculation about the flywheel that was used is still going on at honda-tech.com, but my opinion on the matter is that it looks like the flywheel being used was a modified stock(!) flywheel. You can see in the “CRX Flywheel explosion 3” picture that the leftovers of the flywheel appear pretty dark, just like the stock flywheel. Were it an aluminum flywheel, there would be a much brighter silver color where the aluminum sheared apart, much like what you see where the aluminum engine and transmission were blown apart.

Anyway, I think I will be spending my $100 summit racing giftcard toward a scatter shield..

Honda Releases New For 2013 CRX At The Denver Auto Show!

Honda Releases New For 2013 CRX At The Denver Auto Show!

New for 2010 Honda CRX

Honda has announced their new ad Campaign for the 2013 CRX SiR today at the Denver Auto Show. Honda shocked the crowd at the Denver Convention Center by debuting the long awaited sequal to the popular sports car, which came as a surprise to show goers and the media alike.  Some speculate that the relatively lackluster design and “fuel efficiency as king” mentality surrounding the previously released and now cancelled CRZ proved to disillusion enthusiasts who were blindsided by the heinous tribute to its iconic predecessor.  Honda designers apparently must have been working overtime, because the new CRX comes just months after word the CRZ concept would be scrapped for cost saving reasons. According to the press kit, the new 2013 CRX will have the legendary K20A 2.0L 222Hp engine and 6 speed LSD equipped transmission, both out of the JDM  Civic Type-R. The car weighs in at a paltry 2000 lbs, no doubt a credit to the carbon fiber seen in the hood and front fenders, and although not listed in the press kit, the Honda rep at the show said they expect to see 35 mpg easily from the new model.

The release of the new CRX SiR, a first for North America, comes after Honda recently cancelled the S2000 roadster and sold off its F1 team, leaving fans of the red H wondering if honda had given up on its racing heritage. This new model however, seems to be a step in the right direction.

edit: Happy April Fools..
