Product Information
1/13/03 - The race car preliminary hit the XS dyno today. Car made 239rwhp @ 0.6bar of boost pressure. Upon further tweakings and couple more runs, the car generated 302rwhp @ 0.8bar of boost pressure. At this point we will need to do more changes to the car and change out the wastegate spring to a more stiffer spring, and will go back to the dyno for 18-25psi tuning on race gas to see how far the stock motor setup will go!
5/2/03 - It's been awhile without any updates, got the car shortly back on the dyno today, @ 14psi the car generated 345rwhp! More to come after we fix MOOOOOOORE problems...life just can't go on without problems, but that is fine because one won't learn if there's no problems. Right now we are getting serious to have the car finished by Summer of 2003, with race wheel setup, new paint job and body kit, and have custom chromoly roll cage fabricated before shake down run.
5/12/03 - Did some clean up and tricks to the car to clean up the air flow and ignition curve, hit back the dyno today again @ 14psi pump gas generated 350rwhp!! Next is 18psi run..we'll see how long the stock motor can last.
UPDATE** 1.3 bar generated 388rwhp on pump gas (91 octane!)- overall air/fuel ratio 11.0:1. Slightly leaner ratio with higher boost level, push beyond 400rwhp on stock motor is within reach. (FYI: The motor that's in the car right now is no different than the average SR20DET frontclip everyone gets, this proves the SR20 is a very capable motor. However, since this car will probably not see public road, we still recommend keeping the HP tame for reliablity reasons).
5/15/03 - Fixed the misfire problem, mix in some 104 high octane race gas, turn the boost up to 20-21psi generated 422rwhp! ** UPDATE *** 25psi generated 474rwhp!!
6/21/03 - Car is waiting for custom roll cage done along with waiting for drag wheels/tires. In the mean time since we are bored we will be pushing the car to 500rwhp on stock block see if it holds for fun.
6/24/03 - The 500rwhp barrier is met. XS was able to achieve a solid run of 503rwhp, 525rwhp was the highest. At this time above 500rwhp the car is maxing out the Z32 MAF. Down the road would have to switch the PFC to the D-Jetro version. It's amazing how much power the stock bottom holds for over 40+ dyno passes now each time at above 400rwhp range, but we have finally shattered the rumor that SR20DET can not exceed 400rwhp without some engine building. Just want to say that reaching this kind of HP is not easy, and certainly now for anyone to just turn the knob on their boost controller. Without precise tuning and fuel system, the SR motor can still blow up just like popcorn in a microwave.
8/23/03 - After 2 months, the roll cage is finished. Now the car will be stripped for paint scheme!
11/05/03 - Haven't had much time to work on the car until now. The car will be ready for paint and new look in 2 weeks. Hopefully the car can be well setup for race by end of this year, we are aiming for race season starting 2004.
