even the 35R sucks on pump gas, it really needs more octane to shine (do you really have the budget for $200+ in gas per track day?)
I would scale back and put a green on the stock block with a good tune… then come to dunnville and play - I suspect you’ll find that more power is the least of your problems. I’m only 300whp and my next $2000-$5000 in mods will probably be all suspension toys and diffs.) I certainly don’t need any more power for now.
