My Dyno Results...


iceman said:
hopefully this gives people different perspesctive on improving performance, with carefully assembled engine (oem b16b parts only) and better tolerances figure makes sense, if spoon assembled id say figures suggest its defo a b16b and makes sense

id be very interested in overall feel of this engine


how long you had the car dunsy ? nice find but how the hell hadnt you spotted that before, that kinda surprise would be better than receiving half dozen new parts

Are you trying to say tht balancing a bottom end will give you more power? which it won't.

Are people forgetting that spoon used to sell the 1.8 stroker kit for the b16b? which unfortunately they stopped selling a few years back

With those results its quite likely it is a 1.8.

When we had the RR day back last year all B16B EK9 were making 165-170BHP with the exception of Matt which was 174bhp i believe. On a dyno dynamics that was done.

194bhp sounds well far fetched for a B16B unless it has extensive work done.

Again, Have you been on the quarter mile yet DUNSY? That should explain a few things at least.

I mean i have supposedly same sort of BHP as you but i can pull from S2000 fairly easily.

balancing is about 20% of building a very nice engine prob not even that and balancing that spoon does is nice but far far from level to what real sweet/high end engines are done to

not many ek9 make the quoted 185bhp which is shown repeatadely from peoples dynos, some lucky ones do and take into acct percentage of engines that are freaky and produce more + some produce no more but are simply quicker than others is down to subtle little things

if people think this maybe a spoon stroked engine then in that case its figures are low (dunsy, this is in no way having a go at your motor, just generic statement, in fact it seems you have the kinda engine i love :nice:)

if it is nicely built spoon motor then frictional losses and bad harmonics will have been reduced increasing performance, it may have set of cams in there that have been degreed and timed correctly or just little tiny of bit of headwork which again could account for quoted peak figure


have you got dyno graph dunsy ? interested in whole band

to some in may seem subtle but when you drive different b series (poorly maintained, highly modded but poorly, modded reasonably, totally oem but rebuilt very very nicely with odd bolt designed specifcally for that engine and not just generic part etc etc you see big differences in performance BUT moreso, engines feel very very different)

Yeah as John said, socket and ratchet on the crank pulley and turn engine over(make sure its in neutral). Remove the spark plug from engine and insert welding rod down plug hole till it hits the top of piston then turn engine over(anti clockwise) till your sure piston is at top dead center(rod at highest point) then place a ruler beside rod and mark a point on rod and also on ruler then turn engine till ruler doesn't go any lower and mark the ruler where mark on rod stops. Measure distant between two points marked on ruler to get stroke length.

Thanks man, Will defo give that a bash soon :)

I pull from S2000s man aye :nice: Quarter mile was Rubbish when i went, Snowy, Rainy and very windy the wrong way :clap:I got a 15.3 on parada spec 2s which we all know are atrocious in the wet.

I Do have a dyno Graph mate, but not on the comp, il try and scan it somewher and stick it up.

The car runs lean and if its underpowered would it be because im running it on a B16b Spoon ECU instead of a Custom map/B18 ECU?

I really have nothing to compare it to really but i test drove a race base a while back and it did feel very flat in comparison to my EK9.

Sam from Spoon Europe reckons its a stroker kit also and he is investigating spoons history of the car going by the serial number on the Plaque.

I have NO IDEA how i have never spotted this plaque, i have even changed the Clutch line right in front of the plate, cant beleive i never saw it before! :nono:
 
I'd defiantly put my money on it been stroked to 1.8 you can argue the point of hp figures but the torque figures are to high to be 1.6 for the given spec.
 
So, If its a 1800, being run on a 1600 ECU, i presume this is restricting the power and points to the underfueling issue?

Yes could be the reason behind it. What part of the rev range was it running lean? and how lean did it get?
 
Top End was running lean, 7000ish Upwards.

i cant remember exactly mate, the guy said he would advise not spending alot of constant time in the high revs though
 
Running lean wont restrict your power, you will run more power if anything but risk detonation.

Problem is you cant be sure its an 1800cc so couldnt even advise getting a DC2 ECU......

Sounds like an absolutely great find! ^But the difference between 1.8 & 1.6 is down to the driver at the track, as by my own experience there is not a lot in it.
 
Correct, Hmm, im going to wait on the Email from spoon with what they know about the car, i wouldnt be surprised if it was a spoon engine though as it has a non OEM Head gasket for sure, thats all you can physically see though.

Will await the email from spoon and update this thread when i know :)

Cant wait to get to the bottom of this :D
 
if your pullin on s2000 then impressive motor and needs to be left alone, get it mapped dunsy on aftermarket ecu as dont know what damage/maybe none going on and release any extra potential there safely

im defo still sayin is b16b in there, doesnt matter whats in there if motor pulls like this one

im in for next goody you find on the car
 
wow...congrats on the engine..im on b18c r.and my torque only 124 lbf max on dyno dynamics..hope to c your graph...and would like to c you afr.
 
Might be the reason it was running a bit lean on the rollers then eh?

BUT, if it was a 1.8 then you would think the ecu in before the spoon one would have been a suitable one

Interesting to see what spoon have to say

Oh and speak to Gerry if you're needing Henrys number
 
Ken, need to speak to geraldine like.

This is exactly what i was thinking, i still have my (what i think is) Stock ECU, there seems to be nothing special about it though, its pretty dull to drive with it in and although vtec pulls strong it feels pretty flat and there is no great kick like with the Spoon...Although the vtec kick has calmed since i added the Spoon TB

Very strange

HMMMMMMMMMMMMMMMM
 
TPS adjusted right on the new throttle body? Might not feel as big of kick if the ecu isn't reading WOT
