why run octane that high if you are not tuned for it??

Lol!

Well... I originally ordered the new 285/35/19 MT ET streets SS to run on my Nismo wheels. After waiting for two months, with no shipment because MT said that tire was still under testing/development - and not for sale yet, I ordered the 305/30/19 ET Street SS tires. When they arrived, I nearly threw my back out dragging them into the garage. These tires were freaking heavy! I pulled out the scale, and they were 39 lbs each!

So, knowing that wont work due to rotating weight, I ordered the 285/18 MT ET SS tire that is 30 lbs!
A whopping 9 pounds lighter!

So, then I ordered the PF01 10.5"x 18" wheels with the 38 mm offset (21 lbs) that centers the tire in the wheel opening. So the 285/18 MT with the 18x10.5 PF01 wheel is 51 lbs.

The water on the track made it spin. On a good track or a good road, the 285/18 MT does bog the engine just a tad.

The car had 5 gal of cheap 87 e10 already in it. To bring it up to a safe octane level for drag racing, I spiked it with an equal amount of 101 just to make the blend roughly 93-94 octane. When stalling a hot engine againt the converter it is prone to detonation. Just didnt want to hurt it. No hp gains were expected.

So the Nismo extra power, horrible riding quality and extra cost don't help the quarter mile times I see....:shakes head:
At least it looks cool...:rolleyes:

All those extra bits weren't intended for better 1/4 mile times.

Finally just barely respectable enough to share publicly, RT being the clear and obvious exception (ready for the shade, bring it). My build thread is up here, but this was basically no prep, 90ish degrees, full tank, NT05R nismo Rays, and my first time in the 11s.

10.72et @ 132mph Not bad for a heavy Vert...

The best mod for your car is the 4.08 gears
its hurts your gas milage
is your car tuned ?

No tune yet!

Planning on E85 and SEB tune next.

Thinking 3.70 or 3.90 gears too and maybe a converter.

You cut a dang good light on that 2nd pass! Great Job.

Thanks JC!

Didnt help much against that street driven CTSV Caddy, that blew by me like I was backing up in a parking lot.

Man those things are fast! 10.27 unbelievable!
