Here's a printout from Jake's website.. ~ 77 hp, 103 ft-lbs.
I'd like to know how to compare my stock 2.0's output (73 hp, 88 ft-lbs at the rear wheels) to this printout. Is "corrected engine output" estimated from output at the rear wheels? Attached image(s)

My Dyno measures flywheel HP.
The *MOST* I have ever seen from a stock 2.0 was 86BHP at the flywheel.. I'd like to see the math from the chassis dyno as it sounds a tad off to me. The engine shown in this graph is a typical stock 2.0, in fact it was the very last one I built that was 100% stock about 3 years ago... The fuel curve should be much flatter and around the .60 range. The stock cam can be attributed to this through inefficiency. The fuel curve should be a mirror image of the torque plot with a slight dip at peak torque since thats the point where the engine is making the most power with the least amount of fuel... Your engine sounds typical, and not really tired at 135 psi, I like to see 145 but 135 ain't too shabby as long as leak down is good as well. BTW, I *THINK* that this was a Bus Spec 2.0 and not a 914 spec... Big difference.. |

The stock 2.0l cars I have seen on a dynoday is around 75-85 Hp.
