Took the better part of 2 days, but I installed the new Helix IC and Dejon boost tubes. Also moved the water/meth injection nozzle to right after the IC outlet in the elbow tube. Gives me another 10-12" of mixing. Also took the time to wrap everything that was exposed metal.

Had a bit of a surprise taking the bumper off. It had 3 extra screws holding it on. Found this additional bar/support. Wonder if this is a coupe only thing? When I first saw it I though...oh ****...will the new IC fit?



Here's what I pulled out:


Here's what I put in:



Initial tests show 15deg drop in IATs when cruising, when the W/M is spraying 20+ drop with 7% fuel trim. Thats with the spray turned down for winter! Can't wait to see how it does in 100+ heat.

P.S.
Eric and crew at Helix rock!

 

Great job with the write up. I am sure this will be helpful to many owners out there. Now go have some fun.

 

Looks good! When you say you see 15 degrees drop in IAT's while cruising, does that mean you are cruising now at below ambiant temps? When I cruise around I am at 10 degrees above ambiant, and about 5 degrees above ambiant when on the freeway. It obviously goes up crazy fast when I get on the go pedal.
