Every real world situation is different. I have seen a glide slow a car down. I have seen many 400's slow cars down. For average bracket cars, I would say from 1-3 tenths. Most people will have examples like above. You can't compare going from foot brake to trans brake launches.

I saw very little difference between the turbo 350 & Turbo 400.

Over the years of bracket racing we can not make either one live very long with my car. We will be going to the dark side of LS1 bracket racing & going to run a PG next season.

A 350 would probably be a tad quicker in a lower hp car, if built right.
Higher hp cars a 400 or pg.
On my car with a 400, transbrake to footbrake about a tenth quicker.

Trans gearing determines if its going to pick up or slow down.
