On my car, larger TBs didn't give me anything extra.

wouldnt t/b only be worthwhile if ur going the full monty?
i mean a bigger t/b (increased airflow etc) would still suffer the same 'bottlenecks' as a stock t/b unless u had ported/polished/ the s/c headwork etc?
fair enuf jsut switching the t/b and nothing else might give u some gains but hwo much are we talking here? 2-5hp? for how much $$???
