With the ceramic coating, its not that big of an issue.
My HP Performance header was almost identical (2 piece, similar routing of runners/collector, but the WG was on the up-pipe instead of the runner collector).
My header was within 1/4" of the motor mount the entire time (the upper metal portion that attaches to the block). I never had an issue... And that header was JetHot coated. I was around 520rwhp when I sold it.
There was a couple people who pm'd me wanting me to get some dyno jet numbers for comparison, so I Dyno'd my car at PSI's (Portland Speed Industry) Dyno Jet and got some new numbers.
For reference, there was a Nissa Nismo 370Z that's factory rated at 350, and most owners expect about 280-300 at the wheels. The same car dyno'd only 250 at Forged Performance's Mustang dyno, but 290whp at PSI's dyno jet.
My car originally dyno'd about 403 on the Mustang dyno, and on dyno Jet on 14psi, it made 456 whp.
Red line is the dyno with my Exhaust cutout closed. about 420hp
Blue line with the exhaust cutout wide open.
I think this is the numbers more people is expecting out of a GT30R.
Car is still running great, still no vibration issues or leaks to be reported. No real issues with heat near the motor mounts either. My manifold was ceramic coated and heat wrapped.
Brian Green is the tuner @ Forged.
