How much gain could I expect from an intercooler with the Dutweiler neck modification.

How much gain could I expect from an intercooler with the Dutweiler neck modification.

Here are a few good threads I found.

On the old gnttype list a few people said they saw 0.1 sec and 1 mph in the 1/4 mile. I changed turbos at the same time so couldn't say, but later going to V2 frontmount with no other changes was worth .5 and 5 mph over the dutt neck once I finished tuning . I loaned it to a friend and he said he felt a little improvement seat-of-the-pants, but not anything amazing. Given the quality and selection of intercoolers available today I can't see spending any money for such a small gain unless you absolutely have to keep the stock ic, and then if you put on the dutt neck it won't really be stock-appearing anyway.

I swapped the stocker out with a Dutt neck one at the track and picked up nearly 3 mph and dropped .25 on a nearly stock car.
