IS Racer
This dyno has quite an interesting story
behind it. This E30 M3 belongs to a JS racer who decided to build
the standard "kit" 2.5 L (pistons, crank, and custom chip) after
determining that his 2.3 L was a bit tired after a few seasons of club
racing. Armed with the standard chip that came with his kit, he
arrived at our dyno showing only a mild 171 HP @ the wheels. Now
being in IS and now competing with the '95 E36 M3's, this kind of power
just wouldn't do! The average E36 M3, although a bit heavier, can
put down some 210 HP at the wheels or 40 more HP with gobs of additional
torque! After our evaluation, we determined that the motor had way
too much compression with the added stroke, and with no help from the
stock cams to bleed off some of the added pressure, detonation was
imminent. Let's just say that a street engine doesn't like to see
11.2-11.5 compression on pump gas! Well, after some careful tuning,
we squeezed out another 13 HP at the wheels with one area that even
approached 18+ HP!
