Talking to the team before practice at Mid Ohio they were cautiously optimistic. They feel that the track was one where being down in horsepower wouldn’t be as much of a disadvantage as somewhere like Road America. However from the very beginning the car had a significant push. They would struggle with this all day Friday.

First order of business was to try to balance the car. To do so they took a little wing out, which required drilling new holes in the mounting brackets. Then a rear spring change was made to try to correct the push issue. But neither issue corrected the problem. All during practice the team had been running on used tires, which may have masked part of the problem.

For qualifying a new set of tires was mounted and the car picked up some speed. Unfortunately everyone else did also and John qualified sixth fastest. Ahead were the Corvettes of Tommy Drissi, Doug Peterson, Simon Gregg and Amy Ruman. Cliff Ebben qualified 5th taking the honor of fastest Ford. The push was still there, but this time a “clicking” in transition was heard, which would have to be addressed.

On Saturday morning, the first order of business was to inspect all the heim joints for play. Once that issue was solved a radical spring change was made in a last ditch effort to cure the push issue. Of course the results wouldn’t be known until the race.

Rather than go into a lengthy report on the race suffice it to say that John was able to finish 4th. One more restart, which didn’t happen as they couldn’t get Amy Ruman’s car out of the sand trap in time, may have allowed him to make a run at the 3rd place finisher. But it didn’t happen, so be it.

Great race, and the dicing at the front was serious but clean. If you get the chance be sure to go out and check out the Trans Am series. Good racing and it offers something that few series do.

 


Some of us can remember when 300 Horsepower was a lot for the street, even some pretty exotic cars were fairly hard pressed to meet that number. But in case you haven’t heard time isn’t the only thing that has moved on.

My first GT1 car.

The car in the picture was my first GT1 car. It had about 550 HP, on its best day, back in the late 80’s. Not bad for a club racer but its 351 engine was almost certainly the best thing about it. The professionals however wouldn’t have considered it.

By the time the second coming of the TransAm series ended they were running 310 cid engines with rev limiters. These engines were, at least for those at the front end of the pack, in excess of 700 horsepower.

But now things have really changed. The 310 has gone the way of the dinosaur, replaced by the 358 cubic inch V8’s. Initially a lot of these were refugees from Nascar. Bought for less than one could build a 310 and producing big horsepower numbers. Initially some people just changed the cam, and maybe something with carburetion and exhaust and went racing. Worked pretty well and now the horsepower numbers were over 800.

But today the bar has been raised again. Some people have realized that an engine built purposely for road racing will out perform a converted stock car engine. This despite the fact that the horsepower numbers are the same.

And what are those numbers today? One racer who reportedly has about 830 HP told me recently ” I can’t pass them (the top cars) on the straight, but they can pass me.” His opinion is that he is 30 horsepower shy of the top cars.

So times have changed my friend, times have changed.

Congratulations to John Baucom and the entire Baucom Motorsports team after their fine 4th place finish in the Trans Am series race at Watkins Glen today.

This was their first return to the track since the disastrous fire at Sebring in the first race of rhe season. After qualifying 5th, with a broken front sway bar he was able to get as high as 3rd where he race most of the race. However at the end he was not able to hold off Simon Gregg who took the position with just a few laps left.

Again congratulations to John and everybody associated with the Roadraceparts.com Mustang. We look for continued success.

 

 


Do you have a maintenance plan for your car? While many of us, if not all of us have a checklist that we go thru between races that may be it.

Do you know when various items on the car were replaced? You probably change the oil and filters on some schedule, it only makes sense. But how long have the rod ends on the control arms been on there? Or the spindles (that probably came with the car when you bought it)?

Part of getting organized is having a plan that includes every critical item on the car, when it was installed, when it was inspected, and when you intend to replace it. Yes, it can be a pain, but think what happens when a rod end or a spindle breaks. We all either have had it happen to a friend or ourselves, some little part breaks that should have been replaced a long time ago.

It will save you money in the long run.

 


Ever had the mishap of a “stuck” caliper? If you have it’s probably something you haven’t forgotten. What happens is that when you apply the brakes the pistons in the caliper press the pad against the rotor and the car slows. All good, right?

But when you release the pedal the piston does not return to its seated position, allowing the pads to release the rotor. How much of a problem is that? When it happened to me a 550 hp engine could barely move the car down pit road. Not good.

Several things can cause this, just disuse, like in a car that has sat for a period of time. Or, more commonly the heat cycles that the brakes go thru eventually deteriorate the seals.

The answer, is of course to add caliper maintenance to your check sheet. Every 2 or 3 races, pull the pistons, check them over and replace the seals. Seals are cheap insurance and it could save a lot of heartache.

For those of you using Brembo calipers, they have a new design of anti-knockback seal. A direct replacement for their regular pressure seal it reduces the issue of pad knock back.

We carry AP, Alcon, and Brembo caliper seals in stock ready for immediate delivery.

Under construction. The lower portion of the chassis taking shape.

Can you guess what type chassis this is under construction? Brand? Well the type is pretty obvious. Its a GT1/Trans-Am/IMSA style road racing chassis.

Brand may be a little more difficult, because it is only the second one built.

Everyone that is involved in racing does so because they have a passion for it.  And part of that passion is a dream. A dream to succeed at the highest level. And of course  we all love to tackle those projects that are a challenge.

Thats how it is for Mark K. one of the principals in Roadraceparts.com. A veteran vintage racer he had dreamed of driving a Trans-Am car. Not just drive it but own it as well. So when the opportunity came about to purchase the engineering drawing for a professionally designed chassis and spares he jumped at it. Of course, knowing that one car had been built and successfully raced made it a little easier.

So in this brief article you can see several photos of the chassis on the surface plate. Work continues and all indications are that the results will be well worth the effort.
