can someone with 17" rims and 45 series tires tell me what rpm your at 70mph? my all-trac came with some 16" rims and i think 45 series tires and at 70mph im at 3100 or 3200 rpm :wtf: i know its a small engine but i had a camry (5sfe with 4 speed auto) and my rpm's would be like at 2700.

engine RPM are higher in the Celica to keep them closer to their powerband.

3000ish is correct for Stock.

I do not know what it will be with your bigger wheels.

In my alltrac I am round about the same rpm. 31-33ish at 70 mph. I cannot guarantee the accuracy though, as my speedo is a bit off.

I have 205/40/17s and I am running right at 3k for 70mph.

I am talking about my 4AFE with an auto though.

If you're referring to the difference between your trac and camry, your answer is in your question. You're comparing a manual shift to an auto. Automatics are geared differently, since they only have 4 speeds, 4th gear needs to be able to run out longer. Auto trannys are also torque multipliers. And on top of all that, autos aren't made to be sporty. Cruising at 3500rpm on a stick is just fine. :bigthumbu

With my 4afe I'm doing 70mph at about 3000 3200RPM if that helps

im at 3700-4000 doing 83mph (limit here).

I was running 17's with 45 series tires on my alltrac and it would chill right around 3000 rpms cruising at 70, sounds to me like your right where you need to be

Using larger than stock wheels should, theoretically, lower the engine RPM at a given speed and improve gas mileage. Of course if your car is rolling on cheap Chinese knockoffs that weight a ton, YMMV, literally.

16" rims, 1800rpms and 6lbs boost give or take a few

around 3100

4000 in 4th gear, 3100 in 5th

You should have seen my 1st gen Integra. 1.6L 4spd auto, 7000 rpm redline. creamed at between 3500-4000 in top gear. lol

Driving for 1200 miles, I drove at 70 MPH at about 3400 RPM with stock 13" tires, 4AFE and 5 spd.
