I'm interested in getting this mod and am wondering about how much faster your 0-60 times will be after the mod if the stock is ~5.1 sec? Ihave never rode in one and have no idea of the difference.
TIA

 

Chad, your 0-60 times will be mostly affected by your ability to find traction after the 410's. With sticky tires you should be able to get into the 4 second zone on mostly stock or mildly modified, manual trans car.

 

Thanks for the answer. So I'm guessing my stock bfg will spin all over the place after changing the gear ratio? Is it on wot or can you let off the clutch slowly and then punch it? I am trying to translate the number of tenth of a second into *fun factor* as I really don't drag with this car and I use it as a daily driver. I'm debating over this compared to a s/c as I don't think there would be much of a concern in blowing my engine with this mod and I may get close to the same performace ???
TIA

 

Same performance? No.

But, fun/$ - yeah, go w/ the gears.

 

So am I looking at roughly say 4.8 for gears and say 4.5 for s/c tuned at ~ 400 rwhp ???

Does that sound close approx

 

I've timed mine at 3.0 seconds flat in the 0-60mph with a SC and 4.10s. And about 0-75mph in 4.5-ish.

I'll go out on a limb here and guess that my KB is responsible for most of the gains.

 

i am going to assume that is on DRs and not street tires....if that is on street tires i am going to die.

i dont want to die

 

My street tires are drag radials... my track tires are slicks. I did the testing at the track, so traction was good and the timing was verifiable (G-meter vs timeslip... less than 0.1 sec variance between the two).

 

That's got to be a RUSH!!!

However, you have a completely modded motor, that's more than I want to put into it.
Now if your saying there is going to be more than 1 second difference with a s/c then you have my curiosity. However, I don't think I would go over 400hp on my stock block. so 0-60 say ~4.0 sec with a s/c or 4.8 w/ gears???

I don't want to spend more than around $5000 more on my car as far as drivetrain

 

at least i didnt die, very nice times though

 

THe BFG's wont spin all over the place if you practice getting out of the hole. They wont stick as well as Dr's or slicks at the track. I ran for a long time on the stock pirellis and BFG KDWS. They do fine for the street for where I am at N/A. With the stock Pirellis I was able to pilot my car to a 13.55 in the qtr at 103 in completely stock trim. After the gear swap I could only muster a 13.4 because of the increased torque multiplication at the rear tires. In short I was spinning bad. A switch to DR's knocked the 1/4 mile time down by a solid 4 tenths. Again I still run the KDWS on the street daily. Practice is the key to traction. Also I wouldn't focus too much on 0-60. As there is way more to good performance than that.

 

With 3:73's my 0-60 is 4.82.

 

Then maybe 4:10's + tires are worth more than just a few tenth's

As far as 0-60 times. That is just how I can best measure performance being that I never have been to a track

 

I'm just curious. Have you priced gears or a blower?

Not to be smart, but it's like asking if I should buy a Corvette or just stick w/ a Cobalt.

But yeah, as much as I'd like a blower, tires will be my next mod, then gears.

 

0-60 times don't tell you much anyways...most would consider the 1/4 mile the true acceleration test

 

gears, less than 1000 and no engine trouble

s/c, over 5000 and possibly cause problems to my engine/ drivetrain


And I didn't find your question smart, I respect most everyone around here and value your opinion.

I'm going to bed now so no more post from me. Thanks for the input

 

I agree with DavidM about not focusing too much on the 0-60 times. When you get into a higher level of power, 0-60 times are limited by traction mostly and not engine power. A better indication of how much you would be gaining with a supercharger verses gears would be a 0-100 time or a quarter mile trap speed. A supercharger might be only 3 or 4 tenths of a second quicker to 60 than a set of 4.10 gears, but in reality the power would feel much more substantial. Let's say a stock 5 speed with 3.55s hits 60 in 5.1 seconds, 100 in 12.7 seconds, and has a quarter mile trap speed of 103.3 mph. A set of 4.10s might drop that 60 mph time to 4.8 seconds or so, and the 100 mph might decrease to 12.4 let's say, with a trap speed of 104.0 (just guesses here). But it is a totally different ballgame with a supercharger. Where the 60 time might hover around 4.5 seconds, the 0 to 100 time could decrease to around 10.3 seconds or so, a substantial difference, with a trap speed of around 112.3 (or more, im just pulling these figures out of my old hiney)...but you get the picture. If i were you and i had an extra 5,000 dollars that i wouldn't miss, a supercharger would be my first priority. Sorry for the long post, but hope this helps.

 

So what would you say about my g-meter 4.6 and 13.5 with 3.55 and stock 18" Goodrich?
Or my best of 4.43 and 12.90?
(Of course this is with me getting almost no 1st gear spin and 50 degree temps).
FYI Don't talk to me about calibration, it is set right.

 

Did you calibrate correctly jk Nice times
