The Ultimate Guide to Suspension and Handling Part I: Wheels and Tires

by Mike Kojima

Horsepower is sexy and chicks dig it, at least a lot of meatheads think that way. Making horsepower is relatively easy. A lot of competent people know how to make power, lots of it. Until drifting became the rage in this country, handling and cornering prowess was for geeks, the road racing elite and autocrossers. Handling was for dweebs that raced around cones in parking lots, or loners prowling canyon roads at night, not for cool people in the scene.


 

EFI 101, Basic 4-Cycle Engine & ECU Operation and Tuning Rhetoric

by Christian Krahenbuhl

Automotive engineering involves a series of compromises. The compromise of designing affordable, durable, and fuel efficient engines that are enjoyable to drive while meeting modern emissions regulations has made the job of EFI controls very complex. Afford-ability and durability are concerns because manufacturers and consumers have limited resources. An engine designed to use some super metal like unobtainium (Uo and atomic number of 666) would be ideal.

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.

Racing, performance, Nissan Sentra and basket case are not words that usually go together. This is a story of how a sophisticated race car was built from a pile of parts with a double dose of hard work and intestinal fortitude.

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.
