Hey Joris, are there anymore plans to do more dyno workshops? I really want to get my Prelude tuned, and see what it makes at the moment after 109,000 miles. Its the H22A5 185hp engine. Let me know!

YES I HAVE A DATE:

It's Saturday 9 March 2013! Geldermalsen, Netherlands. More info will follow.

Next week saturday already.

Counting on 8 cars right now.

My own D15Z8 will be stock tested and then eCtuned to get engine behaviour more linear.

My wife will bring her almost stock D14A4 (except for SRS stainless exhaust) to get a baserun, later on I'll swap the IM for a back to back test what the IM swap really can do.

LakaiD14 will bring his car for a spin!

There will be a D15Z6 with turbo which has to be fully mapped if I remember correctly.

There is a nice ESi that will get the full mapping.

Also a (stock?) MB3 will be there.

The other two cars are a S2000 and Civic with B18.

Great news!Looking forward to the results

ild wish 2be there

I know I know I am really late... but I have some very interesting results.

Only as a warming up:

My stock VTEC-e MB9 Civic which should have 115 bhp, had 114.7... I put it's timing spot on Honda specs and I get Honda specs. Wheel losses where normal, 0.12 bhp/kmh.
So I would like to use this case t prove the accuracy of the dyno of Speed-Centre.

With some eCtune we could actually put less fuel under WOT and get sharper ignition to get 121 bhp. The default VTEC-e is rich, it has AFR of 11.5 at WOT. This explains why it is guzzling gas when over 120 kmh, and can only be driven lean on long straights around 80/100 kmh. Then it gets over 16 km from a liter, Aerodeck Civic. Normally 14 which is even when eco driving.

Now the EJ9's of the day, my wife, stock EJ9 90 bhp with only a big exhaust from the cat, Stainless SRS... one to be advertised as silent... 106 bhp. But with perfect AFR at WOT of 13 and changing ignition timing only got it to less bhp. Wheel losses identical to my MB9.

Than the best result, LakaiD14 with his non-VTEC D14 with Bisi cams, high compression and CNC-ed head. He got 131 bhp! Way better than in the beginning where his D14 would hardly pull 110 bhp.

There is more, there is dyno's... but low on time, but I promised Owen more than a week ago to post. Sorry Owen and the rest, you still deserve to hear the entire story, but this might fuel the discussion about D14 tuning a bit.

Very good findings!!
Lakai is using a 2nd stage cam right? So that is about the max power of a non vtec n/a d14 not extremely tuned?

Wow well done Lakai! Can't wait to see the full write-up, thanks Joris.

Are there any dyno charts available?

Most definitively, but I still have to scan them.
