8 speed S'crew, 2001
Anyone out there ever install gearvendor's under/overdrive? I have a 2001 S'crew with minor mods like a cold air intake, Roush cat-baks, 18" wheels, a performance drop, and aDiablo chip with aset of Bassani or BBK headers in the near future. Anyway Gearvendors claims you can beat the Lighting in the 1/4 mile with what I have now and the following; swap out the 3.55 rear gears for a set of 4.56'sand install their overdrive/gearsplitter unit giving the S'crew an ultra low launch but still retaining almost factory identical 8th or high gear. Both this set-up and an aftermarket blower will cost about the same. Your thoughts on this matter or better yet someone with some experience in this area. Thanks

Good Luck beating that Lightining, I think the best you could hope for is either an old pre SuperCharged Lighting or one being driven by someone unexperianced in proper launch technics who proceeds to sit and smoke his rears at the line
From what I understand a 2002 Lightining with sticky tires and a good driver can easily run in the very low 15's to high 14's all day long. Add to that the extra weight your SuperCrew has deal with and , well . . .
I wish you happy hunting, me I'll just stay here on the porch and watch this one.

When your shifting your not accelerating...multiply that times 8 and the lighting will be heading down the return road while your crossing the finish line. I've also been drag racing since the seventies and have found that only about one person out of a 100 can properly speed-shift a stick most of the time, that's why you find 99 percent of drag vehicles run automatics unless they're very high HP cars...then they run $5,000+ Lencos or something similar that only uses a clutch for the initial launch.
I'd run the blower for racing and the Gearvendors for towing. Deen

Actually my S'crew has an automatic with overdrive, your basic stock tranny. The way the new gearvendors work is all electronic. I understand the overdrive units come with a push button and Gearvendors claims you can run through all 8 gears at full throttle. Heres the stock auto gears;3.55/ 1st to OD
2.71
1.53
1.1
.71
Heres with 3.55 factored in 1st to OD;
9.62
5.47
3.55
2.52
Heres with the 4.56 gear change plus the tranny factored in;
1st to 8th
12.35
9.64
7.023
5.478
4.56
3.55
3.23
2.52
I figure if anything I can always add a blower later on. Wont hurt to experiment.

Post your question in the "transmission" area and see if you can snag one of the readers who actually has a Gearvendor...there are one or two out there. I was researching running one a year ago and from what I remember someone posting that there is a lag in the shifting for the overdrive, it's not fast and firm like a automatic with a shift-kit. Then again I've never actually run one...so I could be wrong. Good luck, Deen
