Dyno numbers 1800

Phil,
No time to give a complete reply. Disagree on HP v torque. HP is the measure of work and that is what accerates a car. Partly a matter of semantics, but it is important to understand that just because an engine has more torque does not mean that it will out acclerate another. Comparing the acceleration of a Volvo B20 with 120 ft lbs. of torque and only 80 HP with a Volvo engine with 120 ft. lbs. of torque and 120 HP will quickly convince you of the correct anwswer to this.
Have just forwarded to you a dyno chart of a test of a B20 with IPD street torque cam and downdraft weber that should illustrate this. Will also send test of 120 ft lb. torque B20 E. Will discuss it further with you sometime.

On dyno measurement, again, not strictly true. The most popular chassis dynos measure the time it takes to accelerate a given mass, their rollers, to a given speed and that is not stricly a torque measurement.

On Steves car being able to out accelerate any stock E, I have just sent him a dyno test of an essentially stock E, that showed much more torque - your measure of acceleration.

Was not aware that you had recommended the cam to steve. I know it is not the same as your cam. If you are the leading publicist for Unitek you are doing a good job. But going back to your Vclassics articles of several years ago on "doing it right", we don't have data yet to show that using Unitek parts is doing it right, any more than there was on using some of the old combinations which data are now showing was "doing it wrong". BTW, I will still pay the cost for you to put your car on the dyno. If you can get a deal like steve's I'll pay for you to put it on twice - once now and once after further modifications.
