Dynasty INTIMID8R Question

[KGL]

I ran a set of Dynasty INTIMID8Rs that I bought in early January in an Scout Adult race. I polished and waxed the bores as shown on the DD4H video, but I just could not get my car to run fast with these wheels on them. I changed to an older set of Dynasty INTIMID8Rs that I bought last July and were polished and waxed the same way and my car was much faster. Do I need to be do something different with my wheel and axle prep or have the newer wheels changed (different molds, different cut)?

42' Best Track

New Dynasty INTIMID8Rs - 2.9712 average

Old Dynasty INTIMID8Rs - 2.9579 average

Take a look at this thread. It may apply to your situation.

Were you running both sets reversed in the rear? These wheels have a very thin inner edge and will flex if not ran in reverse.

 

[KGL]

Hogans Racing - Yes I ran the wheels reversed in the rear. I might have to re-prep the new wheels and see if they are any faster.

It just seems like the newer wheels are harder to get to go fast, but my older wheels are for sure much faster than the new ones.

are you using a spacer between the body and wheel?

 

[KGL]

Obsessedderbydad - yes I have the spacers for these wheels from John. I put the large diameter side to the body and the small diameter side to the wheels. I used a business card to set my gaps. The wheels spin nicely and do not rub against the body.

It has to be something you did. My SP from the last race had wheels on it that I thought were really slow several months ago. It's something I did. /images/boards/smilies/biggrin.gif

I have been having similar speed problems in the SP class. In fact I think my car may of even finished last at the February race. I've had a few last place finishes lately!

So anyway I did some searching on wheel prep, while I didn't find anything in particular about SP wheels, everything I did find on wheel prep pretty much says to follow the tips in the DD4H video. These wheels are pretty fragile so make sure the wheels are not broken or distorted in anyway.

As for me... Well I stripped my wheels clean and will re-prep them again. Perhaps I can get a badge for the most last place finishes in a season!

Later!

I think I can give you a run for your money /images/boards/smilies/smile.gif

Not if I start racing this class. I'll have a lock on last

A couple photos of how to install the wheel spacers properly would be great...

I will try to take some pics this weekend. Step by step.

That would be awesome...Thanks Hogan.

Put the wheel on the lubed axle and then slip the spacer on, small lip towards the wheel, then install the axle in the car body.

 

[Hogans Racing]

The parts

Insert spacer, small side towards wheel

Place your gap gauge between inner hub and axle head. Push spacer towards wheel until touching

Put the whole assembly into car until the spacer is against your car body

Pull your gap gauge

Now your good to go

That's how I do mine, I'm sure everyone has a different way but this should be a good way to start. Hurricane if you start smoking me in SP I expect a helpful hint!

 

[BulldogRacing]

Thank you so much!

 

[HurriCrane Racing]

Beautiful!!! Thank you Hogan. I'll be sure to return the favor but I don't think you have to worry about me...

Nice pictorial Hogan.
