U.S. Vintage Trans-Am Racing Part 2
You think removing a good racer from VTA so someone with less skill can win a race will make a class more popular ?? Isn't that what the B,C,D,E ... Mains are for ???
So I guess my question is are the R1 motors good for VTA or should I have gone with an X factor. I don’t have a dyno. So I guess I’m not sure what would be the easiest way to get the most out of that motor.
My Trinity XFactor $99 (not top 5%) puts out about 24.5k rmp at 42* timing
My R1 (in my son's motor) puts out about 14k rmp at 42* timing.
both are 2019/2020 motors and fairly new.
People will have their own opinions, but I can gear down a 24k rmp motor to get the torque I want (for a shorter/tighter track), ...yet I can't gear a 12k rpm motor to get the higher rpm I'd want (for a larger/longer track). The Trinity in my opinion offers more tuning options (via physical timing and gearing). On the track my Trinity has a LOT more power than my R1 and my laps are faster. period. This is my personal experience, others will have their own opinion.
I had a Motiv MC2 previously and that was a good strong motor as well. My R1 just seems sluggish.
Again, my personal opinion so take it w/ a grain of salt. Also I am sure someone can get a lot out of an R1 25.5, yet I don't have that knowledge as to how to do that (I know how to gear, adjust timing and check motor temps as well as use my motor analyzer to give me insights to what the motor is doing).... so I am sure others will know how to make the R1 fast.

The RPM difference your finding between the R1 and the X factor is huge. Had I known it was that big of a difference I would of bought an X factor just to have a bigger window of gearing. I don’t have any kind of motor analyzer so I am just going off of my best lap times and motor temps trying to get the gearing right. At my next race I am going to try a big jump in gearing going from a 3.5 FDR to 3.8 just to see what happens.
I should add and I am sure others will echo the same statement, higher rpm doesn't always mean faster on the track sometimes the opposite can be true. Also if a motor is overheating then those high rpm's are useless. But, my xfactor is faster on the track, so there is that.

USGT ...all the rules lately are meant to slow the cars down some and give it back some character ...body weights spec motors ect ....the cars had reach much faster speeds and the super thin bodies and super/hyper cars had took over... nobody cared about the class as a whole except a handful of us... so things got changed. But it did hurt attendance. Numbers for USGT are down...
USVTA... speeds are good.... body weight in effect...and like stated, motors are on par...
fyi...lazy racers who complain about getting the FDR and timing correct or best ,to get the maximal out of the motor...saying its to much work...kill yourself, you being silly... with the 2 dozen adjustments on your chassis thats going to require you to get right, setting the FDR and timing is a breeze...
ppl just realize I never here anyone at any VTA race locally or Nationally say I got beat by a motor in VTA...and if somebody did...they lying

Dave that was at my race...1st numbers for the 25.5 Novak which set the blueprint for 25.5 ROAR motors...and yeah tech is a must no matter what you run or class

3 races 3 different motors back to back to back.... whats not equal?... oh 98.635%....98.611%...98.605%... how fair and equal you want it?
I will say though, anyone that thinks they are fast in VTA should check out the USVTA Southern Nationals at Apex in the fall every year. This event draws the "who's who" of VTA talent from all over the country. (Not to mention, the locals at this track are no joke!) The track is amazing....the racing is amazing....the food is amazing.
If you want to see how you stack up, get humbled at the largest (I'm assuming) USVTA event of the year. Myron and the entire Apex crew put on quite the show! Me and my buddies count down the days every year!

Excellent runs Myron! But if you had a spec motor you could have run over 99% consistency.
EDIT: Just for clarification, I could NEVER beat Myron Kinard, that guy is an amazing driver! I'm just having some fun because I've only been above 99% consistency twice in my life! And to be honest, I'm consistently SLOW!
I'm only for the spec motor to reduce costs and only because the motor is $80. If the motor was $120, then I wouldn't be for it. It does remove one variable that good racers can use to their favor. If you are smart enough to time your motor correctly and run the correct gear ratio, you will beat people. So taking away that advantage is a bad thing in overall racing.

oh I have ran 99%...I actually have a 99.89% in one run...Ill find and post it...lol
thank you for the plug David...and yes its true and also another reason I care so much for the class...its our bread and butter at our track and my 2 to 3 events per year

Just an observation. The faster cars in VTA at my track can turn 34 laps in 5 minutes. Back when we ran 27t burshed on foam tires the faster cars turned 34 laps in 5 minutes. Does the class really need to slow down?

EDIT: Myron, are you still running your TC7.2? I can imagine that car will be competitive for quite a while. Also, what will you go to when you do decide to change? Our Team Associated driver in Arizona went to XRay. I raced nothing but Associated from 1982 to just recently. I've gone to Awesomatix, love the car!
Yes, but if club races only have 8-10 racers in that class it would be stupid to have a,b,c mains
