Revenge of the Nerd- Fear and Loathing in Las Vegas or Top Fuel Fun!

By Mike Kojima

A couple of weekends ago I took my 9 year old Daughter Christa to the NHRA Winternationals in Pomona.  Being the jaded 9 year old she is, she loved the Top Fuel cars, liked the funny cars and thought the 6 second Pro-Stock cars were lame because they were "too slow".  In between runs I explained how the inner workings of Top Fuel and Funny cars tick.  She was pretty amazed at some of the facts I told her about the cars and wanted to know how I knew so much about them.  I told her the story of how I was a crew member for a Top Fuel Funny Car last year during SEMA week.  I learned a lot about these amazing cars that day and I'll tell you the story I told her.

DSM Injector

Ask Sarah- DSM Fuel System Tips

By Sarah Forst

Dear Sarah

I read your last article about using a properly sized fuel system and wondered if my fuel system is adequate enough for when I finish my engine build.  I have a 1995 Eclipse GS-T that I’m upgrading to the 16G turbo.  Is there an easy way to determine how big of injectors or fuel pump I need so I don’t run out of fuel at full boost?  Any other helpful hints?

Revenge of the Nerd: Bravo Toyota!

By Mike Kojima

Today Toyota announced perhaps what is the most extensive, comprehensive and expensive recall in the history of Automotive manufacturing.  The recall involves eight of their best selling models from the Camry to even our Project Tundra.  2.3 MILLION vehicles will be affected by this recall. In an unprecedented move, Toyota has also stopped all sales and production of the potentially affected models as well. This affects more than 100,000 brand new Toyotas in the sales pipe line.  This is STOPPED, dead cold, with thousands of workers at plants and dealerships who as of next Monday will be sitting around twiddling their thumbs. This recall will probably be disastrous financially for Toyota.

RC engineering 1000cc injectors for EVO 4G63

Ask Sarah- How to fix your EVO

By Sarah Forst

First, repeat after me- you can’t go reliably fast if your wallet is on a diet!  Although you haven’t given me enough information to properly answer your question as I don't know what other parts are on your car, I will give it a guess assuming you are not spending much money on your 4G63 to begin with. Your current setup includes too small a turbo and probably too undersized a fuel system for those boost levels.  Let’s start with the stock turbo on the Evo VII.

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.

Fast Lap With Billy Johnson :  Auto Club Speedway Roval (Video Inside)

By Billy Johnson

Auto Club Speedway, previously known as California Speedway is a relatively new track built in early 1997 and has been the host for many racing series including NASCAR, IRL, Motorcycle, Grand-Am, and even JGTC. This D-shaped oval incorporates 11-degree banking on the front straight with 14-degree banking in NASCAR Turns 1 and 2. This track also has a series of infield road-course combinations with the largest and fastest utilizing the oval’s front straight and first two turns before going back down into the infield. This 2.88 17-turn "roval" is a common configuration for everything from Grand-Am to track days.
