Intercooler, exhaust, twin plugs, fueler, K27-7200. You have a great build.

We do not know if you have ports or cams. That might make for a 10-20hp swing if you had a larger turbo.

Most that do such a build run a 1 bar boost spring. With the goodies you have there is no principle difference between the US and Euro.

The K27-7200 is a great quick spool turbo but it sets your limit to about 330- to 360rwhp or say 390 to 425 chp if you are lucky with CIS.

If you go to a larger turbo there is another 20-30 or so HP to be had but then how much fuel your system can put out, even with the Andial will become your limiting factor. The Andial can only add about 10% more gross fuel over stock and take you to about 450chp.

Dyno is the only way to know what your HP is for sure and they even vary.

Fitting an MSD RPM switch in line with the boost pressure Hobb's switch on the Andial fueler can help get rid of the probably fat air fuel ratio that often comes with such a system in the mid range and make for a noticeable improvement.

Again, given your turbo if it is a 7200, you are probably a solid 400chp car.

If someone went to the effort to twin plug and add all the other goodies I would be surprised if you do not have cams and ports.

Add one of Brian's larger capacity turbo's and you should have a solid 450hp car and if you can get enough fuel maybe, maybe up to 500chp with the right tuning.
