This was done on a dynojet 228c ....which I believe to read a bit low.... lol



Setup:
Bpi flowstack
3" intake pipe
crower3 cams + crower cromoly retainers and eibach dual springs
rmf header (old design...i wants a new one y0)
2.5" cutout, basically the header is open to a Y about 6 inches after the collector

tuned on s200 by jdogg

The peak power numbers aren't important, the engine was getting very hot and the air in the garage was worse nearing the end. They were using no fans or anything in there, so the temps by the intake were a lot higher than the computer thought, so the SAE is probably killing me a bit here....there were a few early runs that made like 203 or something at the peak, but they sucked in the midrange....

Notice the one line that makes best peak power made horrible midrange. Advancing the intake cam 2 degrees and retarding the exhaust cam 1 degree (adding overlap) added a lot of midrange power, and took a bit off up top. Midrange > top end for me, so I'm happy w/that

Overall, I'm pretty glad about it. I didn't expect great results on stock compression with no head port or anything done to the intake manifold. Actually, I'm glad I didn't end up losing power down low.

Oh and I would have posted this in the dyno thread but its archived now

Pirate, pm me for the .drf files

 

Not bad, man. Future mods plans?

 

You almooooooost had it..... You or your bro kept talking about hitting 200 WHP. That sucks that with the 197 HP the torque took a nose dive! It looks like conditions at the dyno could have been more favorable though. I wonder what would happen with the newer RMF....

sometime in the future I'll be doing a 95mm crank and type s pistons deal, and letting brad do a little magic with my valve seats, but who knows....

Thats weird with my crower 2 I put down 190 and 160 tq on h23 vtec

 

1.00% correction would have been 203.24 whp.

You definetely would have picked up another 5-10whp if you could have done runs with 185-190 water temps. What were the IAT's reading? It was 66 degree's which isn't bad at all.. the humidity wasn't bad at all either.

this isnt an h23vtec

your graph looks pretty good matt. I bet it pulls very well!!

The heat just looks to be killing the top end. No other reason for the power to just fall off so quickly. I bet the IAT's were pretty high. How much time did you let the motor sit between runs?

WHAT? WTF's the "rabbit?" It wasn't the rodent comment was it? Back to 98vtec?

BTW matt, your torque down low sucks, midrange makes up for it a little though. I assume that the idle is pretty stock?

yea yea, i wanted my OG name back.

OH, did you take out the IAB plate for that dyno?

 

Do you have a baseline of the original HP or one before you installed the new valvetrain and cams? I would've expected more outta this engine. I assume this is a USDM Hdeucedeuce? Sheyot I thought that JDM's put down 200whp tuned with I/H(RMF/SMSP)/E tuned. The temp and humidity seem pretty reasonable to me.

 

good numbers...

I don't have the datalogs, so I don't know the IATs, but I would assume they're pretty high....the computer was open to ambient air, but the engine bay was shoved into the back of the garage, under a shelf, with no fans or anything....so I'm assuming it was pretty hot under there....

maybe 3 to 5 minutes in btw each run, not much time...

The idle is a little "lopey" sounding, but other than that it is very stock-like. I attribute the low end sucking to the open header and the big tb...no? Sorry not everyone around here drives a frankenlude lol 95mm crank should take care of some of that problem....though nobody has given me a concrete answer, will a set of type s pistons clear everything with the 95mm crank and h23 rods?

As you can see, the first run is the baseline, before the cams. The line that dies off sharply at 7k is the stock cams. The engine is jdm, again, I believe this dyno reads a bit low. If I ever get an extra few bucks and a few hours I'll drive to greensboro and get on a 248c and find out if this thing reads the same or not.

Either way, it feels good.

Blake, the IABs were still in there for this dyno. They're out now though....and it threw the tune off a good bit...

 

I haven't been keeping up on that manifold thread, but did you do anything to you IM?

Well when I had my crowers in my h22 I still put down 187 and 150 tq. I would have just thought He would have made alot more whp. I am not knocking his dyno in any way. Just trying to figure why the numbers were low. I figured he would have broke 200easy closer to 210whp.

Im loving the midrange, jdogg does good work.

did you make any mods to the intake mani?

you will love the 95mm stroke, I know i do! with the types and k23 rods and crank, you should clear ok. you will DEF want to clay especially since you have crower 3's .

not all dyno's read the same. Go do some research on what it takes to calibrate a dyno and get everything setup and you'll see how and why dyno's read differently. Altitude makes a difference as well. Theres alot of factors as to why you cannot compare dyno runs that were made on different dynos.

 

did u ever run ur car in the 1/4 prior to the cams? it would also be a good measure of how much it gained if u run it again and compare the times

BAH! u knew what i ment, funny thing is just found out they do also make a k23, oh well to many

 

o rly?

happen to know any specs on it?

it has a variable valve turbo and i-vtec only on the intake cam since the turbo is valved and it's awd. that's all i know about it.

 

i was thinking more like bore/stroke/rod length

 

i was thinking that but i don't know it so i just told you the obvious stuff. hahaha.
