Is it just me or do 3.73's and a 700r4 suck. I run out of rpms at the end of the quarter. And my car wasnt that power full. I was only pulling 13.7's

Just out of curiosity how could it be the engine. At the end of the quarter I was spinning 6000 rps. And I was scared to push it any further.

What size tires do you have? Do you have an aftermarket tach? I'm at about 5200rpm through the traps. It's been a while so It might be slightly less or more than that.

I think my tire size is 245 50 or 40 16. Stock Iroc rims. I do have an autometer tach. mph wise I was going 103.
