Ask Sarah

By Sarah Forst

I know back pressure is bad. Everything I remember about high school physics and everything I read over the years from SCC and Honda Tuning tells me back pressure is bad. I made that statement the other night at the pub to a friend. I found myself trying to make the argument without any scientific facts. He drives a 5 year old Mustang GT and claims he needs back pressure for his engine to work. He claims to have dynoed it with open headers and it lost power.

MotoIQ Project Aprilia SR50

Project Aprilia SR50: 100 MPG Madness Part 2, Engine Internals

By Mike Kojima

In our last edition of Project SR50, we had reached the limits of simple bolt on modifications which left us with a nicely running Scooter, capable of just over 50 mph with acceleration good enough to keep up with traffic and 115 mpg. With more time, we are really taking a liking to the refined Aprilia SR50, which rides, handles and brakes better than any scooter in this displacement category. We also like its sporty looks. The SR50 is the king of urban commuter scooters and we are going to take it to the next level.

Nissan Silvia S16?

Merry Christmas From Nissan!  New S16 Silvia?  Oh God We Hope Not!

MotoIQ Staff Report

It is rumored that the new S16 Silvia will be front engine and rear drive which is good but it will be powered by a 1.8 liter turbocharged engine with a class trailing power output of 200 hp.  Come on Nissan, with a turbo you gotta do better than that.  It has been our contention that Nissan has forgotten how to build a proper 4 cylinder engine ever since the demise of the SR20DE and its variants.

Project Pathfinder Part 7, External Shock Adjusters

By Mari Umekubo

In our previous installments of Project Pathfinder we corrected the sloppy handling and loose steering of our machine.  Our project is handling superbly, more like a sports sedan than an SUV.  Our next mod is one more for convenience than adding any additional performance.

Project Nissan Sentra Spec-V part 4: Installing Sway Bars

By Mike Kojima

For racing, adjustable swaybars are important because adjusting the stiffness of the front or rear bars helps adjust the amount of under or oversteer a car will exhibit under hard cornering. Adjustable bars are critical as they can be adjusted at the track much faster than changing springs or other ways of altering roll stiffness to change the understeer to oversteer ratio when tuning the suspension to suit the situation.

As the Silver State Classic is in all classes except for the Unlimited Class, a high speed TSD rally, it is critical to stay as close as possible to the class target average speed for the win. Of course this is harder in the higher speed classes.

Project Scion Wins WERC Endurance Series Championship

MotoIQ Staff Report

The Scion road racing team added another highlight to their 2009 season with yet another championship. The six-hour win at Thunderhill clinched the season championship for the Western Endurance Racing Championship (WERC) series. The team won every race, save one, en route to the E1 class victory, for a near perfect record…impressive, especially in an endurance format series. The team also accrued more points (585) than any other team in any class in the series. The Scion tC race car was completely bulletproof even with the engine spinning 5,000 to 7,500 rpm for three to six hours straight.
