I'm putting a single turbo on my tremec equipped 95 gt. I've read before that boost likes to have highway gears to pull against. My current gears are 3.73s. Would it be a good idea to put the stock 3.27s back in, or should i leave well enough alone? My stang is a street car that will be used for some open track days at my local road course, and maybe some occasional bracket race duty. The car has a full interior, a/c, p/w, p/dL, p/s but has been stripped of nvh crap, radio, back seat, dogbone, has a tubular k member]. dunno the weight yet... My mechanic has a full weight '05 GT with a hellion turbo kit [417 rwhp @ 5 psi], stock gears, five speed and shelby 20s. I road in it today, kinda feels lazy until the boost comes on. Puts out 2.0 60 foot times and 12.10s at 118. Could i expect the same results from my 95 GT if i put my 3.27s back in? would the 3.73s make up the difference on the low end [like they already do without the turbo] or would it maybe reach the boost too soon and just blow the tires to shreds?
