Dyno Test – 13whp In A Bottle – RSR RAN UP Oil Additive
As RSR tells it, nano technology is basically a dispersion of certain elements to a nano scale level by lasers and chemical reaction methods.

The Holy Grail for SR20DET owners is a true six-speed transmission. The promise of shorter gearing and an overdrive 6th for freeway cruising is sometimes just too good to pass up.
Like a good set of tires, drivetrain is an often-overlooked area of car tuning. Many obsess over blowers, exhausts and wheels but when it comes time to get that project buttoned up, the cheapest clutch kit is usually shoved in.
After waiting for the temperature sensor to normalize back to 83-degrees F, we completed another 20-second burn cycle at the same distance. Our new ending temperature was now 95-degrees F. That’s a 54% reduction in heat.
The NT05 is Nitto’s latest maximum performance offering. With a low UTQG rating of 200, it’s matched up against the usual SCCA Street Touring standouts like the Falken RT-615, Yokohama Advan Neova, Toyo R1R, Hankook RS-3 and Dunlop Direzza Sport Z1.
For the average real world driver, the Continental ExtremeContact DW provides a better balance between cost and performance and will provide more than enough grip for the street and, occasionally, the track.
On track, our palms get so sweaty that the steering wheel and shift knob can become slippery. Being too slow to catch a tank-slapper or missing a shift because of grip, well, sucks.
The Yokohama Advan Neova tire displayed high grip and sharp steering feedback on track, especially through the very quick Turn 2 (average 87 mph) and Turn 8 (average 119 mph) areas.
Toyo sells other tires for those purposes that are both quieter and longer lasting. The R1R is an r-compound racing tire disguised as a DOT street tire. But if you’re interested in putting every last bit of power down to the ground or autocross in the SCCA’s Street Touring class, then please read on.
The stiffer a chassis is, the less it will flex when forces are applied to it, i.e. through the suspension. This means that forces from the road surface will be contained and absorbed by the suspension rather than being allowed to beat up the body shell.
The problem with lowering your car excessively is that the roll center is always lower than the center of gravity and will actually fall more than the center of gravity with a decrease in ride height. This is bad for steering response, handling and basically ruins the entire point of buying a lower, stiffer suspension.
At the moment, it seems most tire companies just want to go to war in the performance street tire market. With outright handling records and SCCA Street Touring autocross national championships on the line, numerous tires have been released with 180 or lower UTQG ratings.
We tested the fiberglass version of the Aero Designs Notus seat, which rings in around the $470 mark. That’s quite a bit lower than any other comparable design fiberglass racing bucket and the Notus includes side mounts and a slider.
If you’ve ever swapped brake calipers, changed to stainless steel braided brake hoses or driven hard, then you’ve experienced the need to bleed your brakes.
The entire concept of track accessibility is changing every day. No longer do you have to have a full racecar and crew to drive on a track. With the explosion in recent years of weekend track days, anybody can take almost any car out on track.
The Sparco Evo is one of Sparco’s most popular racing bucket seats and it comes as little surprise why. It has many of the features and specs that performance drivers want and none of the excess junk that everybody doesn’t want.
Sold by Sparco as a competition seat, the Circuit is also available in carbon fiber (S Light Circuit) and in a slightly wider version (Circuit Pro).
A quality unit, the Takata brand’s racing reputation was hurt (in our opinion) by the early adoption of its products by car show loving compact car enthusiasts, many of whom had never seen a track before.
Quality-wise, the Sparco harness is very good. There is no latch-and-link (which we don’t like anyways) design sold by Sparco, only camlock quick-release. This camlock is made of plastic and opens and locks quite easily.
If you’re only going to try out a track day or it’s one of your first couple times, by all means rent an open-face helmet or buy a cheap unit. But if you end up going more than once or, more likely, get hooked, buy a decent unit.
