98 LeSabre 0-90; 90*, up a 5-degree grade; top end sux!!!
Headed home from work early today. Decided to take the long way home through the foothills East of San Diego.
Road was straight, noone in sight a mile ahead or 2 miles behind, and I had the camera...so what the heck; stopped, footbraked to 2000 rpm, and took off:
(This vid shot at air temp 90 degrees F, going up a long 5 degree grade.)
All I can say is, dang
this L36 runs out of breath above 4500 rpm.
I'm hoping a 2.5" DP and high-flow cat (next mods) will provide some minor high-end relief until my project heads are ready.
