On Alp's first run today he turned a time 165.624 MPH which was higher than the existing record in the class. This qualified him to bring the bike to impound and return tomorrow morning to make the return run. The speed for the return run will be averaged with the first run and with luck, it will be higher than the record.

The weather will probably continue to be good for the remainder of the meet.

Steve beat me to it, but here is the rundown:

The old record in the A-VF (Special Construction- Vintage Fuel) was 149.973 by Performance Indian in 2018.

Alp's run yesterday was 165.624 MPH

Alp's run today in the opposite direction was 170.653 MPH

The average speed is 168.139 MPH

Assuming the math is correct and the bike passes scrutiny, that should be the new record.

Congratulations to Alp & Jalika and the whole crew!

I assume so too, since his record in Modified frame (more restrictive than Altered aka Special Construction) Vintage Fuel record with a 650cc Triumph motor is 173 MPH. I think he has yet to add nitro to his fuel.

Bruce,

I don't think Alp would change classes. This is just my own opinion, but he probably wants to address any problems that have cropped up specifically at this meet. He may also want to redesign something that needs some type of adjustment. Additionally, he would want some more time on the engine so he knows how to squeeze more out of it. Finally, when he strips the engine down he may see something that needs a repair or replacement.

I would guess that he will keep working in the A-VF class and if all is well he would go the El Mirage meet at the end of October and see how well the bike working. The bike needs to be tuned differently for all of the fuels and with nitro, you have to tune differently for all of the different percentages of nitro you might use.

When you consider that this morning at Bonneville the density altitude was 4200' and this afternoon it was 5800' you can't guess at jetting and timing when running straight nitro.

What are those two altitude reading equivalents in barometric pressure?
I don’t think it translates directly to air pressure. I believe it has to do with temperature and humidity, as well as pressure.

I guess the timing is by SCCA? These would then be National records ? To do this with what were bare crankcases only ten months ago is phenomenal and utterly amazing. To set a record on its first trip is amazingly amazing!!

The video of the start of the return run was done by Bill Lewis, who is Dan Chase's friend. I had passed it along from Dan Chase in Colorado. Dan has a place in Florida and when Pat sold the engine to Alp, Dan and Annie were kind enough to transport it to Colorado, where Alp and Jalika picked it up.

Thank you, Dan, Annie and Bill for the help!

Most racers use a Relative Air Density gauge to adjust for weather conditions:

Alyn,

SCTA is the premier timing organization in the US having set the standard for timing at the Bonneville Salt Flats since the beginning. All of the records of Rollie Free, Marty Dickerson, Dave Matson, etc. were recorded under the auspices of the SCTA. They are also the sanctioning organization at El Mirage dry lakes.

If you look at the top of the page (green lettering) you will see "2020 World Final Results." Click on that and this screen pops up. The yellow items are the links. Click on the link you want and if the info is there it will open. The info is uploaded at various times when it has been processed.

Alp is No. 113B and he has been running on the Short Course. Click on the short course times for Sept 29th and motorcycles are listed after cars, so he is on the second page in numeral order for the number plate (11 down from the top).

If you wish to listen to the broadcast of the event click on the green lettering at the top for "Live Streaming" and you can follow along. Racing starts at 9:00 in Utah or about 11:00 EST.

It is on right now:


It is a small operation, so there are short spans of nothing! If you turn it up you can often hear background noise.

The cars and bikes in impound have qualified for a record and run first every morning in the reverse direction. They are timed by the mile and the drivers/riders have to match their times to the mile that they achieved their fastest time in the day before.
