The NHRA's Glen Gray said if the screw supercharger cars are allowed to compete in NHRA Pro Modified, they will be scaled back on overdrive pending testing results. Earlier this year during an ADRL event, Pro Extreme raceer Jason Scruggs hit the eighth-mile speed traps in Georgia running 213.54 miles per hour.In an effort to encourage more participation, the NHRA is considering allowing supercharged racers to run the “C” version of the PSI screw blowers similar to those run by competitors in several major eighth-mile organizations.

Glen Gray, director of NHRA Technical Services, confirmed this with CompetitionPlus.com today.

“We are evaluating adding this combination,” Gray said.

“We are evaluating adding this combination,” Gray said.

Currently this supercharger combination is the most prevalent within the popular ADRL and X-DRL series’ within the Pro Extreme divisions. While these cars have been as quick as 3.5-seconds in the eighth-mile, Gray confirmed the NHRA will take steps in the name of safety and parity to back the performance potential down.

“Parity is of key importance to us,” said Gray. “We have very good parity right now. We’ve worked very hard to get it to where it is. We want to keep that parity going forward. Our plan is to keep the current three combinations where they are today in respect to overdrive [supercharger] and boost pressure [turbocharger] and really, top speed.

“What we will need to do is bring the performance level of the screw supercharger to the level of the roots. Obviously now most of these cars are running at a lot lighter weight, and our supercharger combination runs at 2600 pounds. More than likely we will add 200 pounds to them. I’m sure we are going to do something with the overdrive.”

Gray said the 128-percent overdrive on most of the eighth-mile combinations will be greatly scaled back.

“They run a lot more overdrive than what our current superchargers are running,” Gray confirmed, adding the current NHRA legal roots superchargers are at 14-percent. “We would have to pull them back to be level with our three combinations.”

Gray believes, if this passes, the transition will be seamless.

“We are going to work real hard to make it that way,” Gray said. “If we need to test, we’ve already talked to some people about testing. If we need to look at screw blowers and look at performance, we will. We will go wherever we need to and do what is needed to make it seamless.

Obviously, if we do this, we’d like to go into 2014, if we do this, and have the parity what it is now. We are going to do everything to make sure that it is.”

In the past, the NHRA Pro Modified series has been contested on an invitation-only basis and if this legislation goes through, Gray couldn’t confirm whether the participation basis would change from an invitation to grade point format.

“We are going to try and encourage more participation,” Gray concluded.
