PROJECT ND: Parts Development, Testing, Measurements, DYNO

[Brian]

Brian,
How much lighter is your branded aluminum front tower brace compared to factory steel bits?

I don't have the stock bits to measure.

SuperStreet TwinTip!

Last prototype here for install and testing...looking good, sounding AWESOME!

Brian, I can't complement your team enough on the power gains with the longtube and the tune. Well done!

Also, can you comment on the difference in sound between the Q, the SuperStreet, and the SuperStreet Twin-Tip, all with the longtube? I'll be preparing my ND for STR, but will also daily drive it.

[Brian]

For me it is the SuperStreet Single or Race with the Longtube....for fun daily driving.

My first choice is the Race, it is easily the most fun, but it might be a bit much for some.

SuperStreet brings it down just a bit. Putting SuperQ on the end of the longtube brings it down to stock sound level thanks to massive resonator we used in the special Longtube midpipe.

[skeeler]

Thank you for sharing your experience. Sounds like the big resonator in the longtube really tames the sound. I'll keep all that in mind.

More autocross fun and testing!

Saturday ran 8/7 spring rates on our Ohlins with big Progress Front Sway bar and no rear sway bar. Old baked out tires in 205mm width, yet still finished Top Time out of 100 competitors.

For SCCA event next weekend changed it up and will run 8/5 with rear sway added back. Have also run numerous other spring combos on these Ohlins, including 11/6 and 9/5 with front and rear Progress Sways. My point is the setup can cover a broad range of rates and work brilliantly.

[skeeler]

Brian, what holes did you use on the Progress bars when running 9/5? Would you mind reporting back with the holes you settle on for 8/4? Thanks.

[Brian]

I don't recall....but I like a more pointy car than 90% of drivers, so the holes I use are not likely to be the holes you want to use anyway.

[skeeler]

OK. Understood.

[Brian]

I do recall we ran 9/6 at Laguna and one of our drivers found it a bit too tail happy such that with that combo we changed after morning sessions to tightest hole for front bar, softest for rear bar.
