Re: LS1 Horsepower Factors
If a Firebird,GTO,Camaro,and Corvette all have different horsepower factors because they are different body styles,then fine.
So how about a lower horsepower factor for a convertible? The top blows up in the wind and needs 40 horsepower off? |

Re: LS1 Horsepower Factors
Well we certainly agree on that ! ! And while you're writing to the NHRA please add my name to the list .Why you ask ?? Tell them i'd like a reduction of horsepower for my COPO convertible and i'm sure it makes more MPH so I should get a bigger reduction than you . Happy New Year to me .........

I met George at the Winternationals about 10 years ago.Great guy with a long history of fast Oldsmobiles.I remember asking him about his car and whose pistons he was running.He said Arias.After he told me that,I didn't ask anymore questions.The small valve and low compression combo is probably a much better combo for Olds 455 racers. |

Although it does look like they are consolidating factors and giving the engines the lower ones. So the LS1 Firebirds that are at 381,should go back to 340 along with the Corvettes using the same logic. |

Re: LS1 Horsepower Factors
George Thomson passed away of Covid in Dec. 2020 in Lake
Havasu Arizona. I was best man at his Wedding years ago. He was a close friend and a lot of the reason my cars run pretty well even today. He also ran a Killer 73 Mustang 351 that was 1 qualifier when he wanted it to be. There is nothing he could not make fly! He called me the day he died and told me he would not make it to the end of the year! I talked to the new owner at St. Louis points race two year ago = Nice Mature Gentleman and it was running fine then! RIP

Re: LS1 Horsepower Factors
Well how the LS1 GTO landed in F/SA @3740 lbs and 40HP less is interesting for sure not as aerodynamic? No Ram Air?
But its not the GTO that's been feeding on their GM cousins Camaro/Firebird, It's the LS1 C5 Vette. Heads-up about 260lbs lighter....who needs ram air? |
