Difference in spool time and street manners between a PT70GTQ and a PT72GTQ

[BetMinesFaster]

Hey guys, getting ready to order the turbo for my new stroker 109 and I cant make the decision between the 70GTQ and 72GTQ, my question is how big is the difference in street manners and spool time going to be between the 2? I have a 3800 stall, and about 20 extra cubes blowing on it, just curious, my plan is to not have to purchase another turbo for this car so I want something I wont outgrow with the goal of a mid to high nine street car....any input would be great, Thanks, Ryan

I think most will tell you stick with a 70gtq.

If high 9's are your goal the 70GTQ will get you there no problem. There are cars deep in th 9's with a 70GTQ.

If you want to make more hp keep the 70 compressor and go gts exhaust wheel and a/r. If your using a 4 bolt set up without reducing spool times. You really need a loose converter. the 76 wheel is just too heavy. Here is a comparison of a 76 gtq vs a 71 gts.

So what about the 72 4 bolt d bb s trim with the new F1 wheel from turbonectics? I would think that it will spool like that 70 gtq. Oh I hope so since Jack is sending me one.:biggrin:

I'm also looking at switching my old 70gtq for a dbb turbo and looking at that exact one 72 bb s trim and the 70 bb s trim. what have you heard compaired to the 70gtq ?? I want something that will spool better than my gtq but there are so many *#$@ choices its hard to pick one
