What numbers did the dyno turn up?
|
mustang dyno = 155 base line, zero mods pure stock
same dyno = 185 with I/H/E and VAFC tuned in.
same dyno = ?? with no power steering, light weight pullies, and light weight fly wheel.
?? = I need to go back up to find out

How do you like the car without a front swaybar?
|
I like it just fine. With 800lbs/ich front springs I feel that I don't really need the sway bar. The car is real EZ to throttle steer, lift in a turn and the rear end comes lose then get back on it and rear end sticks again. It also takes about 20lbs off the front of the car.

Who is SMBS? In regards to the racing front radius rod bushings (spherical bearing). Did they give you a noticable improvment?
|
I can't find the link for his web sight right now, but they sell a kit for other hondas that use the front radius rods, however they are not a perfect fit on our preludes. They still work well, but I'm in the process of making up some specifically for preludes that should be a little better. You know how our cars like to dart from the left to right under hard braking? They seemed to help this some, and I'm sure they help keep the contact patch in place. They do what any good spherical bearing should do, they don't let the suspension move in ways we don't want, but do let it move freely in the direction we want (zero bushing bind).

Where did you get the K-mac adjustable upper ball joints? Is there much benefit in using them?
|
http://www.k-mac.com/ They are used on my car to get even tire temps from outer/middle/inner for each front tire. They basically adjust the amount of camber. However, I have had a few problems with them working loose so I'm looking into a custom adjustable upper A-arm. FWIW my chamber settings are usually -2.5 front left, and -1.5 front right.

What type of ECU are you running? What type of tuning?
|
Stock OEM ECU with Apexi VAFC tuned for full throttle only so OBD2 will not screw with it. I also have a secondary O2 simulator to keep the check engine light from coming on because I have no cat and no 2nd O2 sensor. Note: my engine is stock from the TB to the header per the Honda Challenge rules thus a stand alone ECU is not really needed IMO.

Is that Mugen rear spoiler functional? Looks cool.
|
No idea. Mugen claims it will reduce drag by helping the air flow off the back of the car. I don't think it makes any real down force. I got it for $50 off E-bay because it was cracked. With a little fiberglass filler, a little sanding, and a little painting I fixed it.
