Dyno testing results

[mattqf77]

Just had my car dyno tested - Max 166.1 HP. Not bad for E30 M20 325i Touring 1989' considering engine is completely standard...

146,000 miles - head rebuilt at 110,00 miles.

[gaszman]

well done mine was 163.0hp 186000 miles on the bad boy

[charlE30]

Both impressive given how old these are getting now

[oguz327]

227.5 bhp for mine last time it was on the rollers, and still does just under 500 miles to a tank on the run.
Not bad for a small boat anchor with Mega Squirt

Is mega squirt system similar to MAF conversion. Is that the only mod you have done. impressive Bhp and fuel economy

[mattqf77]

I've also had a dyno test run done with Speedtouch Mild eco torque chip - Max 164.3 bhp
This was just done as a comparison..

so you lost 2bhp using a chip? did you gain any torque though?

Nope! Megasquirt is a standalone programmable ECU that comes in kit form

[mattqf77]

No gain in torque either - Max 163.9 HP

Standard BMW chip :

Max 166.1 HP - BHP
Max 165.2 HP - Torque
Max 165.1 HP - Flywheel

Speedtouch Eco Torque chip B25M20 :

Max 164.3 HP - BHP
Max 163.9 HP - Torque
Max 162.9 HP - Flywheel

There was increase in torque surge between 2000 - 2500 RPM peaking then drops back to that of standard. Maybe explaining feeling of increase in mid range torque.

Will scan dyno chart

so a waste of money like 90% of chips then.

Just picked mine up from Circuit motors. M20 2.5
190 bhp and 167 torque. Thought torque would be higher but impressed anyway

[Cook318IS]

Not quite the same but on the speedtouch chip i had fitted to my m50 it made less bhp + torque than it did on the standard chip. But it did seem quicker somehow, and the 7krpm limit was awesome.

Does it feel faster to drive with the chip in?

[mattqf77]

Feels bit faster from stand still - not impressed by dyno result though
