LS3 Throttle Response - Stock TB or 102? Will the difference be noticed or minor?
Off boost part throttle?
Tip in vs Mash it
I currently run a 102 billet TB (DBW) with piping from the intercooler that runs from 2.5" outlets to 4" into the TB. I was wondering about going going down to a stock TB to pick up response. I doubt there would be any power loss as I'm not pushing hard and won't see north of 1000rw. If the difference is not great I'll stick with what I have.
Looking to build a forged blueprinted LS3 with stock stroke but run Darton MID sleeves and take it to 4.125" bores, add studs top and bottom and build a durable 388 that I can lean on lap after lap and day after day. I can't afford ITBs so thought I'd stick with the stock LS3 intake and wondering if TB is ok being so big

Thanks guys, for a turbo it is actually quite responsive off boost. I run about 38 degrees timing off boost on light throttle and fairly lean, so response is about as good as a stock LS3. Was just seeing if I could pick up on that lol Anyone who has been around a race carb build or an ITB setup knows what uber response is. Pretty hard to get that in a turbo
