Perhaps not as 'far away' from L88 performance as I may have initially thought. This was 2nd of two runs at North Weald a few years ago. Couldn't do any better than that on the day with major wheelspin issues up at about 80mph on the concrete runway surface. Engine was relatively freshly built and theFantastic video watching all those great cars. A lot of close runs and I noticed a lot of the time the Vette was the winner mostly because they had quicker reactions from the green light.
Now all we need is a video of the L88 vs your Vette Roscobbc.![]()
And one other thing - he’s running a 4:56 diff !!I'm guessing a numbers of things 'help' the Vette beat the other cars - A. weight (or comparitive lack of) and better front/rear distribution than the others - B. IRS - C. upper end torque and ability to 'rev-out' - D. an experienced driver pulling 'hole shots' every run. I'm guessing none of them were running slicks. I thought the Olds was actually the most impressive - notice how well it got 'off the line' and how good the front to rear weight transfer was........
Where did you see info re. 4.56 diff Andy?And one other thing - he’s running a 4:56 diff !!
On the video that OneBall posted ^^^^ a caption flashes up the car’s spec 430bhp, 4 speed, 4:56 gears.Where did you see info re. 4.56 diff Andy?
Nice one thanks.Perhaps not as 'far away' from L88 performance as I may have initially thought.
See what you mean Andy - yes, 4.56 gears on the Vette and.......4.10 gears with auto on the Hemi Super Bee - so yes a fairer match. If one looks in to powerband characteristics of the L88 engine the powerband it is all developed at 1500 - 2000 rpm higher than what would be considered normal for 'street' vehicles and hence the need for lower gears to be in the 'power band'. The Hemi Super Bee presumably 'needs' the lower gear-set to counteract its heavier body, even with an auto transmission. My long ago owned 'drag pak' '71 429 Mustang hds a 4.11 gear and auto........horrible, noisy and potentially dangerous out there on the street - 4000 rpm at 70mphAnd one other thing - he’s running a 4:56 diff !!
