I can attest that this car is an absolute BLAST to drive! I believe there is def more power in there. This car gets better MPG's than mine. :( Hope that changes with Megasquirt. ;)

Good job Joe.

How has your MPG been affected?

awesomeness. I miss my m42. I jumped in my eta the other day to drive it up and down the block to keep the fuel fresh and I was really disappointed. No more revs !!!

while the numbers are solid with room to improve... the car looks F'n fast standing still. Beautiful.

Me boosta :)

[iamsam]

There has got to me more power there. 180 is a good whp number, I bet it is a quick car, but for a turbo, I know you can make more.

Nonetheless, I am sure it is an absolute blast to drive.

What is your speculation on bhp?

[Hey_You]

Congrats on your numbers. Get the ignition sorted out and up the boost! We want bigger/better!

Finally got it done for you guys... and for me obviously. There is more power left in it but I only had 3 runs (got 4 though) and I wasn't really tuning a whole lot during the cool downs.

Run 1 (3rd Gear Pull)



Not bad... but not great. 170.74hp and 167.86tq

Run 2 (3rd Gear Pull Added some timing above 5200rpm)



A little better... picked up some torque but left the efan on so had to redo this run. 167.92hp and 170.33tq

Run 3 (3rd Gear Pull Same as above because Efan was left on - Woops)



Still getting better... picked up both hp and torque by turning off the efan. Guess that thing really sucks some juice. 174.88hp and 173.86tq

Run 4... no video. It looks just like the others though.

Guess we should have been running in fourth gear the whole time... now I know for next time. 180.89hp and 208.41tq

There was a hiccup in this pull and I am thinking it is spark blowout. The dyno operator agreed it was probably the case. You can see it on the graph at 4550rpm.

My 3rd gear pulls peaked at a 164kpa and my 4th gear pull peaked at 168kpa. So about 9.5psi is what I am running. I posted my data long for the 4th pull below along with the dyno graph. Let me know what you guys think... suggestions, criticisms, etc. I'm just glad to have numbers on it now even though I'm sure there is more power there.
