Not arguing, just asking.

I ran my 135 at my track on Friday with stock everything (including engine oil, brake fluid, etc...) except my piggyback tune which adds around 80 hp. I did 25 minutes at a time out there, pushing the car the entire time. The brakes did not fade and the motor stayed at around 280 degrees (340 is limp mode on these cars) the entire time. This was about 15-20 laps each session, maybe 20 minutes between sessions, 4 times. I couldn't honestly lay down 5 continuous hard laps with the Z without some major brake fade or my clutch overheating pretty bad.
I put my setups and lap times here too:
Car / Anticipated Crank HP / Modifications / Best Lap / Top Track Speed:
370z / 332 bhp / R-Comps, HP+ pads / 1:50.7 / 119 mph
370z / ~355 bhp / hotchkis sways, R-Comps, HP+ pads, high flow cats, stillen exhaust / 1:46.5 / 124 mph
135i / 300 bhp (Probably more like 250) / M3 front sway / 1:57.4 / 114 mph
135i / ~370 bhp (Probably more like 320) / JB4 map 5, M3 front sway / 1:53.1 / 122 mph
The above laps by the 1 had some serious heat soak. I also only had access to 91 octane, with 100 octane it can run more boost and the hp goes up to about 400 bhp. The car pulls much harder on the street than the 370 did, which was confirmed by some DynoMaster for Android runs showing sub 10 second 0-100 times, where the Z could do around 12 seconds. Unfortunately, it does need some sort of intake temp cooling to hold the higher HP on the track. No problem on the street when you only do bursts of acceleration, but on the track the intake temps really hurt the FI engine (just power wise). This did not seriously affect the driveability of the car, but it did have a very noticeable loss in power. Luckily, my methanol injection kit will not only dramatically reduce intake temps, but will effectively give 105+ octane gas as well, allowing for much more boost. I hope to find a 370z to race on the track once I get my R-Comps and meth kit installed, it should be a pretty close race if he has the same setup I used to have on my old Zizzle
