I was going to say, it sounds like the car he's talking about started in second, no wonder he lost his ***, had he started in first he could have probably edged the firehawk or whatever it was out

 

Just wondering why you think 4.10s is too much gear for this setup?

 

is that what your running? if so, tell me how long your first gear is? or is it completely a waste because your spinning? or are you going through clutches more than a professional race car driver? I can already tell you the answer. Unless you're going to be running bias ply slicks, or Mickey Thompson ET streets, 4.10's are useless.

The basic point of going to a steeper gear is higher torque multiplication. Well, guess what, for most DR's, and all street tires, when your running a blower/turbo set up, you don't need as much torque multiplication in first gear. I'd even go so far as to say that with these set ups, the steeper the gear the more useless it is, just because of traction.

One of the major bennefits of a centrifical blower is the buildup of torque, that way you don't have to fight with traction or burn up your clutch to get ahead.

for a street car, it's too much of a gear, 3.73's work, but after having the 3.55's I wouldn't reccomend anything steeper. Hell, most turbo guys, and I probably will to, step down to 3.31:1 gears.

 

but haven't there been some people that have done it and had some success?

 

if your a great driver and don't mind running drag's on the street, then go for it, but otherwise your going to fight for traction, and first gear won't be long enough to pull in, so your going to be a pure second half car

 

Totally agree, I was just reading about this awesome sleeper TT '90 hatch. From the outside is was a spot on stock looking fox and was making 570HP. He mentioned for daily use, the way the motor makes power, and for how he uses it (daily driver, some track) he was considering going to 2.73's from 3.08's. A little extreme but you get the point...

 

Personally I would've stayed with something like 3.73s, but the guy took off after so we didn't get a chance to BS after the race. I don't know what gear the other guy started in but my buddy was in first and when he pinned it I was thrown back and not let up until he let off. I'm really impressed with how he modified the car. He tells me the next thing is either a 100 shot or if he has the kind of money to drop on his car maybe a set of heads. I can't wait to see how fast this thing is.

 

Awesome story simply because it's not often I hear of Ford vs GM without someone on either end getting butt-hurt. Sounds like you found a decent guy on the street for once.

 

Yes, I run 4.10s, full bolt ons, spec 3 clutch & alum flyywheel, alum driveshaft, full suspension, blower cams, battery relocation running 451 rwhp on 11psi and 501rwhp at the track on 13psi & 100 octane. The car turns consistant 7.7-7.8s thru the 1/8th mile with mickey thompson e/t streets on stock wheels. On the street, 1st tops out about 35mph. From a 20 roll, the car is useless on street tires, but from a dig, it hooks reasonably well(wheels spin at 4500rpm+ but not major). This is on nitto 555 p275/40/18. On Mickey Thompsons it dead hooks on the street.

 

not to sound pedantic, but didn't I say, almost and I quote "unless your running drag radials on the street, that anything above...."?

For you, 4.10's work, and that's with Mickey Thompson Drag radials, which is what I was saying, So I think that I was right on the money
