K20A2 Dyno (dropping vtec)
Well I finally dynoed the K20 hatch today.
The car was built by Cody at Lovefab, I just cleaned up the tuning and really haven't had time to fix the vtec issue. BUt I got one OK pull on the dyno, didn't get a chance to tune it on the dyno because of vtec dropping out. But I got one pull to 8K.
The car is just a stock K20A2, has AEM EMS and a lovefab prototype header (this thing is pimp
) attatched to an Apexi Dunk exhaust. The cam timing was messed with a bit and it feels a lot better on the top end.
Just for reference this dyno reads low so I am pleased with the numbers from it
This is the graph.
Vtec dropped right before 8k, so I got off it.
Vtec dropped a little before 7.5K, this is what happens when it drops out.

Like I said to you earlier today... I hate you. 
This is going to be the second time I've said this, but I should have done a K20A swap.
Good power, John.

The power is great. It comes on fast and strong. Vtec transition is great at 4500. I have a video hosted. Let me get it for you guys. You should right click save as.

He isn't kidding on this either. I'd estimate it probably 10-15 low. But.... that's a dyno. Doesn't exactly matter though.
But. I don't foresee much track time with this car with it's VTEC issue.

How's it any flatter than a B?

More than likely an oil pressure problem in the head. Everything else has been checked.

K's make a ton more torque than B-series. But usually all vtec N/A motors have pretty flat tq curves.

I will turbo the CRV if you let me have it for a month and make it faster than your EVO.
