for comparison.
Here are the results from our new low reading Mustang dyno testing of the 18g's on the 370Z.
Stock 91 octane
271.2 RWHP (289.1 Dynojet equivalent)
224.3 RWTQ
8psi 91 octane
395.9 RWHP (422.1 Dynojet equivalent)
351.1 RWTQ
(46% more than stock)
11psi 91 octane
494.4 RWHP (527.1 Dynojet equivalent)
395.9 RWTQ
(82% more than stock)
hope it was ok that i did this. sometimes its nice to have all the info compiled on one thread.

so the comparison.
On dynojet:The 16g kit produces 440.7 hp and 422 wtq at 10psi with a stock exhaust on a ipl...(alittle bigger than regular exhaust on g)On Mustang dyno: 18g kit made 494.4 hp (527.1 dyno jet equivalent) and 393.9 rwtq at 11psi with a stock exhaust.
Things to rememeber.
1. 16g is more like a stock turbo car. Boost instantly and sam says you have 4 psi of boost at 2200 rpm so hard to keep it out of boost if you drive on the highway alot.
2. 18g looks like boost comes on around 3000 to 3200 range.
3. The added trq on the 16g goes away once you open up the exhaust more but your hp climbs magnificently.
Both are great options depending on your driving habits, location and what your using it for.

Thanks for the consolidation, keraxis. Don't forget that the 16g dyno (for the G37) was done on a dynojet, while the 18g dyno (for the 370z) was done on a mustang dyno. You may want to include GTM's "dynojet equivalent" numbers for the 18g kit in your comparison.

Someone with the power
Never noticed before but we dont seem to have a group buy tab under market... that is just not smart because people may miss amazing deals and vendors will lose money. For example a $6000 twin turbo kit.

I would hope but doubt it.
parts dont really interchange between our cars so probably not going to be together. Brackets are probably in diffrent places and all piping is probably diffrent.
Hint hint... if you combine them then it might sway people to stretch to get them with the almost guaranteeing tier 3 buy.....
