This is a multi-faceted question so I think it best belongs in this forum.
I'm just about finished all the winter mods (see my signature) to the GN and am ready to go racing, at least I think. Last year when I raced I was only able to hold 5psi on the radials before they would spin or I would push thu the lights. I want to be able to build more boost (10-15 psi) at the line, but I'm not quite sure what would be the best way to do it without tearing sh*t up or screwing with the driveability of the car. Here's the options I was thinking of:
I think the S-10 cylinders and bigger shoes would probably work best, but I have heard that they can make the car react wierd during street driving/braking, which is what I primarily do with the car. But could someone answer the following questions:
I have sticky Hoosiers QT's now so I don't think spinning them once they're heated is going to be an issue.
I race with a bunch of F-body and Mustang guys. One of them INSISTS that a higher-stall torque converter is the answer. I've told him time and time again that with a stock turbo, intercooler, heads and cam I don't need anything but a stock D5, and that a $500-$700 converter is a damn expensive way to be able to build boost, and that brake mods or different launching techniques would be much more effective and less costly. He's stubborn as a mule and it's really starting to piss me off.
I'm convinced that he is just of the mindset that since a new Trans Am benefits from a converter, then a TR will too. Now I'm no genius when it comes to TR's, but I've done a lot more research about them in the past year than he has in his life. Not only do I think that he's dead wrong and that my car doesn't really need one, I am hesitant to put one in my stock (w/shift kit) 200R4. Also, I can't afford a converter, and I certainly can't afford a new tranny right now.
If I'm wrong them please say so. But can anyone shed some light on these subjects? Can someone provide me with some advice so I can (hopefully) shut this guy up once and for all?
Thanks for your help

Here's the options I was thinking of:
- S-10 brake cylinders and bigger brake shoes & line lock (cheap option)
- vacuum brake conversion (a little more $$$ option)
- E-brake launch (free workout for my left leg)
I think the S-10 cylinders and bigger shoes would probably work best, but I have heard that they can make the car react wierd during street driving/braking, which is what I primarily do with the car. But could someone answer the following questions:
- Would the vacuum brake conversion allow me to hold more boost? Is the lack of brake holding power due to the weakness of the Powermaster?
- How much boost can I realistically hold with the E-brake? Has anyone had any luck with this practice? Is it going to damage anything?
- Should I try using both the E-brake and the footbrake at the same time?
