Dyno'd the Ls/Vtec today...
 

Well I figured since I would be making another 1/4 mile pass at the next event at (pacific raceways) I should probably dyno tune the car just to make sure everything was ok at higher boost levels.

Started off making 238 to the wheels on the first run, and found out the car was running extremely rich, 10.0's A/F all the way past 5000rpms, after doing a bit of tuning, and getting the A/F to a more relistic level, the car was making decent power. Boost was bouncing from 11-12psi & holding a decent 12.0 to 12.7 a/f

Overall I ended up with 263.5hp & 201tq, The red line shows my base run back when the car was NA (167hp) that wasnt the best one, I have no idea why he posted that one.. But it was 174hp the best NA. Maybe it was just to compare...

So roughly this engine is around 310HP at the Crank, I'm happy and its pretty much what I expected. I could probably tuned a bit more, and work with the cam timing, but thats another day :)

The low speed cams on the GRS's look like they make some good torque. 263 should get you some sweet peg legs :)

A pirate walks into a bar with a steering-wheel on his crotch.

The bartender says, "what's with the steering wheel on your crotch?"

The pirate replied, "Aaaargh, it's driving me nuts!"
