dutt neck intercooler claims

[6-Banger]

I have been reading that you will get an increase of about 2psi just by the dutt neck mod on a stock intercooler. Does that mean that if I can run 20psi on 93 and alky with 0 knock right now with a stock intercooler, if I modified it with a dutt neck I will be able to run about 22psi with 0 knock?

The 2 psi gained with the neck is from freeing up restriciton. If your wastegate is set at 20 lbs. right now it will probally produce 22 psi after the Dutt. neck with no other changes. In return you should be able to easily tune the car in for the additional boost. Every pound of boost gained is around 10hp. I run a similar setup & have found the necked stock intercooler to be a good piece with the addition of Alky on Mild combo's.

Thanks, I didn't know if that was how it was going to work.

Every car, turbo, wastegate, chip etc... acts differantly but the gains are worth the small expense of the Duttweiler neck.

will a Stock IC with the Dutt neck keep you from getting into the mid to low 11ns

11's are no problem with the stock intercooler before the bigger neck. It's all about the combination & freeing up some restriction only helps. Check out some of the TTA's with the stock intercooler & Alky that are running in the 10's.

If you're doing 93oct and alky you should be able to handle 22 no problem.

Dutt neck is a great mod in my opinion, I really felt a difference after I installed it. A lot of people say they didn't notice much improvement except for the extra boost, but I noticed better spool/acceleration.
