Low 60' times.....
Need help/info on necessary mods to pull 1.5 and quicker 60' times. My car is an A4 which I bought on purpose to go the high stall route. Also, can someone tell me if there is an issue with stress cracks, or bent frames...and if so what is the best protection against (besides not racing 
)
Please forgive the newbie questions, i'm going from a 600 HP GN to a vette and trying not to make mistakes.

A Yank YPT4400 has netted me a 1.49 60' so far with 397rwhp. A SS4000 gave me a 1.51 with 325rwhp(stock H&C). Both are excelent choices. What do you plan on doing motor wise? N/A, FI, etc..?
No issues with bent frames, etc.. unless you like to do wheelies.

Well, since I just came off a high HP turbo car and dealing with expensive race gas etc... I was thinking of going N/A and nitrous. However, a couple of these supercharger kits are calling my name.

Ok, the plan is to go with a 3.73 gear and at the very least a 3600 stall convertor with a trans from RPM. The GN's used to have a problem with certain convertors ballooning and pushing the crank out of the front of the motor. Is there still an issue with this? Thanks for the help guys. The board appears very friendly so far.

I have over 250 passes on my 97 and a welded in 6-point............no issues. A welded in 5/6 point can only help rigidity

Well a cage will definitely help if not completely stop the car from having any issues with cracks etc. This is good news though, the stinking GN had multiple cracks on new paint job from just a couple 1.5 60' passes. Of course, it had no cage but it did have all the frame stiffening goodies on it.

The GN is a soggy noodle compared to a C5. 
As for ballooning, it shouldn't happen as long as you tell your converter builder that it's for forced induction or spray. Then they'll add a anti-ballooning plate and extra clutches.
