I've made a few changes lately. 

Firstly I converted to an e-throttle ITB setup from a BMW S1000RR. 
This, by some luck had a port spacing almost exactly identical and right size for a 1NZ motor.
It also means I've got cruise control connected up, which works awesomely.

I'm now running some slightly shorter runners that have given some gains in the 6000-9000rpm region at expense of some midrange. Good for drags. 

I also went to a 13" wheel setup, so a 205/70/13 M&H dot rated bias ply tyre for the front. Then some skinny alloys with 155s on the back. 

Car weight is now around 790kg.



So I went to the drags again, and it ran great! 

I ran a 13.49 @ 99.5 mph. 

Had a 2.09 60ft so that could still probably improve a bit. But on the whole, was real happy with it. 
I was using a new shift light setup that I wasnt quite used to, so ended up buzzing the limiter a little more than ideal. 
I'm looking forward to getting out there again and experimenting some more with tyre pressures and launch rpm to find what's good. 
On the whole though, the car's been great.

Here's a video of the 13.4 run:
 

Also, because this is a weird/unusual engine and car combo. Especially for drags.
Some gentlemen from the Moving Our World youtube channel came along to film a night of racing. 
So they put together this really cool video, which is a nice keepsake for a successful night with a new PB.
 

Some interesting slow motion footage of the run where I was launching at 7500rpm with only 7psi in the fronts.
Still heaps of wheel spin, but it's amazing how a proper drag tyre will just keep propelling you forward anyway.

 

 

 

what year s1000rr did the e throttle itb's come off of, i just bought some off a 2018 myself for my 2zzge ke70, I've heard whispers of canbus driven which is a slight worry

[2018 bmw s1000rr e throttle itb's, 2zzge, fury x]

i fear i might have made a mistake buying some e-throttle itb's off ebay, they are from a 2018 bmw s1000rr bike, i was trigger happy about fitting them to my 2zzge with my fury x, does anyone have information on the throttles, because im starting to think they are canbus driven and not the typical 6 pin job im used to seeing
