Replying to: billjenkins (Oct 24, 2008 11:37 am) You likely need a valve job. Also Automatic or 5 spd. Also, which model do you own? Mine is not the ultra high mileage XFi, nor is the most powerful LSi. How many miles on yours? I've timed mine using the odometer/speed checks on the Interstate. I do know the actual speeds and the actual speed variations on the speedometer, as I stated previous. Two people can own the same car, and yet it may perform differently based on a variety of factors including how the engine the was broken in, etc. Even my gutless high air drag 70 Datsun 1200 could top out at 105mph. Breaking 100 mph in any economy is unremarkable. I've even done it in VW Diesels (down a mild grade).LOL

Replying to: billjenkins (Oct 24, 2008 11:37 am) My GEO Gives 64 MPG all of the time at 58 MPH; up to 49 MPG City; it will hit over 85 MPH any time in 4th gear, and I have no Idea how fast the top end is If I where to guess I would say around 105 to 110   If you can only hit 74 MPH then you could try setting the ignition timming up to 7 degrees BTC rather then puting down the people that are telling you the truth.
#10 of 10 110MPH in my Geo by J_B_G Jan 22, 2009 (6:28 pm)
I have regularly done 110MPH+ in my 92 GEO metro, it cruises best about 85-90, the only criteria keeping the speed down is the fact that Geo's have a single core radiator, and the temp will keep climbing the faster you go for extended periods. I had the same prob with my 86 Chevy Sprint, and the only cure is to either slow down in relation to the ambiant temp, or add another radiator from another sprint or Geo in front of the existing one and "T" the hoses using copper pipe fitings. It's fixes the problem as the prob is with flow/quantity, not cooling ability. I'm 6 foot and weigh approx 200 pounds, so if your Geo won't break 100MPH on flat ground using a 5 speed manual trans, you need a tune, or a new engine. Also,, I have never had mine "shut down" from a speed cuttout, though I had an F150 do that at 105mph, then start back at 100. RADAR DETECTORS ARE LEGAL IN CA, buy one or get outta my way!!!
