It's all on what you want to spend. Unless you find a smokin deal on a mainshaft with a 2.25 2nd, you're going to have between $600-$1000 for a new one. Changing from 2.06 to 2.25 is splitting hairs for what you are wanting to do with your car, and the $600-$1000 you'll be spending on the mainshaft could be spent elsewhere on the car for a greater gain in performance/e.t. A close friend has a slightly hotter engine combo in a 1750lb. car, and has run 11.60's in the 1/4 with a 3.78/2.06/1.58/1.22 combo with a 3.88 r&p. The 3/4 combo is not very streetable though.
How many 2nd gears have you broken by having the 9 large drive teeth removed? Removing these doesn't weaken the gear, it actually helps it by distributing the load equally over the other 21 instead of just 9. Kind of like using a larger half of an 091 1st gear lessens the load on the small half on the mainshaft by distributing more of the load over more of the surface area of the teeth.
Is your current trans broken? If not, why not make a few passes with it with the new engine combo? You may find out a stock 2nd gear pulls the way you want. You may also find your 1/8 mile trap speed has increased to the point that your original 3rd choice may have been too low, and you might be able to use a stock 1.32 3rd thus lowering the overall cost of your build even more. If you still want to spend the $600-$1000 for the mainshaft, and $150-$300 on an aftermarket ratio 3rd, that's fine. Just don't be dissappointed if it doesn't lower your e.t. as much as you are wanting.
Another shop to consider is Jim's Custom VW's in Columbiana Ohio. http://jimscustomvw.com |

Well. I didn't mention money Or delusions of ET's.
The box I have is a Rancho pro street that I have for about 5 years and the last three years has taken a pounding each year more than the previous.
I have a gearbox with 2nd out ( specifically it's the idler and slider, The main shaft with 1st & 2nd is fine)
that I drove on the street with BF Goodrich radials. I did hammer is often on the street and lost 2nd. Only then did I learn about the engagement teeth thing. The main principle is that the smaller teeth do not fit the slider correctly and slap inside.
I appreciate your suggestions and thanks for the tip of builders.
I already have 3 quotes for a drag box. waiting to hear from PEP. so far prices range $2800 - $3500
If I thought that a stock second gear would survive drag race with slicks I would try it.
I feel more confidence about the stronger Weddle gears.
I have some thinking to do thanks again.

Sorry to stereotype. A Weddle Mainshaft is pretty much a done deal, and can be crossed of the list as a weak point, so it does add peace of mind. The previously mentioned car ran 300 passes on slicks with the stock 2.06, and another friends car with mild turbo 2110 has made quite a few passes with one on DOT's. If you've already had an issue with a stock second, that will always be on your mind, so I would go ahead with the Weddle Mainshaft. The diff, and r&p will be next on the list of weak points, but you should be able to get a few hundred passes without an issue.
Not sure where you're at in Ky, but the North Coast VW Drag Racing Association had an all VW Class at this past August's Bluegrass Supershifter's Event at Thornhill Dragway in Morning View. I'm pretty sure they are planning a return trip in 2015, but keep an eye on the NCVWDRA thread over on the UAC for updates if interested.

Yes, I am paranoid about 2nd and I'd like to save current trans for back up/street. Did your friends 2nd survive or let go eventually? Nice to know it can survive that long.
I'm in central KY. I had no idea that any VW racer where going to be at that show. I was going but a family member schedule operation canceled that.
I have been following UMTR and looking at the BSS. I know Thornhill too.
Waiting for Trans builders responses. Thanks again for all this info, I will definitely keep an eye out for the NCVWA.
Trying to get the South East Gassers to let me run with them.
Thanks again!

| The turbo car is still together going strong, so I don't know the exact wear condition of 2nd. As for the other car, I personally disassembled the trans, and 2nd gear was actually in excellent shape. It had minimal wear on the engagement teeth, and no cracks in any of the drive teeth. |
