Dyno tuned today.
 

Well finally got the car on the rollers today. And good news it made it home under its own power, alot more of its own power.

Setup:

1992 1.6 5spd
150K stock motor
Greddy kit with the only remaining part not upgraded being the turbo
ETD manifold
Tony's 2.5" DP to 3" cat to 2.5" exhaust straight through muffler
Stripes intercooler kit
460cc inj
Braineack MS with EBC boomslang
CLutchnet 3X PP and 4 puck sprung disk
Godspeed rad

Had a hell of a time making the EBC work smoothly but we got it. Added spring to help the WG. Got it to make 12-14 psi steady. After 20 or so pulls on the dyno made best of 189 Hp, not to bad but I was really hopeing for over 200. Its got a hickup at about 4500 rpm that we could not iron out, popular answer was that it was an ignition miss and would be solved by closing up spark plug gap or new coils. I'm open to ideas. The tach jumps when it happins.

But I got to tell you 189 hp in this light of a car really felt great driving home. I'm sure its faster than my mildly modded 5.0 DD.

I have a graph and I'll get it scanned in the AM and post it.

Anyone want my datalog let me know I'd be happy to let some if you experienced guys look it over.

Any bets on low long the rear lasts? Auto-x Sunday!

Thanks for all the help getting this project going!

Post a screenshot of your timing map when you get a chance. Interested in seeing what you guys came up with. Considering Ben made close to 250 on the greddy kit, maybe that was 17 psi though. I still think you should be at 200 at 14 psi.
Have the dyno plots to load up?

I was thinking the same thing. With those mods you should at least be at the 200 mark

Thats fuckin good hp goal for that psi dammm son lol nice :bigtu:

190 at 14psi is pretty low, but it may be the dyno. What dyno, what gas?

Was on a dyno dynamics dyno. 93 pump gas

Spark map

that's about right on a dyno dynamics dyno. Add 17% to that to get equivalent dynojet numbers.

FWIW, that's exactly the same horsepower i got on my modified greddy kit on a dyno dynamics dyno at the same PSI. I had an emanage blue, Vortech FMU, and 1.8 tantops though. ;)

VE and EBC map

Question, what are you guys using for a Rev limit?
And what type of limiter are you using, Fuel cut, spark cut, or both?

If you're running a cat, you want to cut fuel for sure because raw fuel destroys the cat. The MSPNP base map has a 7000 soft cut and 7200 hard cut rev limiter with fuel only cut I believe.

7100 soft cut to 10 degrees
7200 spark+fuel cut

I NEVER hit the hard cut. It usually just sits there and howls away at like 7150rpm. Only times I ever hit the hard cut is on autocross courses where I stay WOT in 2nd gear all the way up to it.

Mike, nice numbers... we can get that EBC working, I know it.
Also, what exhaust are you running?

AND NEXT TIME TELL ME WHEN YOU'RE GOING TO THE DYNO!!!! I WANT TO PLAY TOO!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Any restriction being created in the exhaust stream from going 2.5 to 3" and back down to 2.5?

The only thing 3" is the cat, figures that would help flow.


Sam Its working on the EBc with the values I posted. There just way off the maps you posted and I thought that was strange. Guess all cars are really different.

You get to see get on a dyon with it next weekend. By then the cat will be a pile of dust on the floor. Well see if that helps.

My concern is the turbulance caused in the exhaust stream by the abrupt change in exhaust diameter. May not have as much factor as I think, but it was good for a few hp on an NA honda/acura motor.
Look at the exhaust stream as fliud, that fluid will most likely follow the bottom of the pipes. As it hits the lip going from 3" to 2.5" it can cause a swirl effect, but not a good one.
I understand your thinking, and I would not say anything unless I had seen it myself before.

add a .1uF cap from js8 to ground. gap plugs at .30"


:useless: <-dyno plots that is.

I think .3" is a bit big :giggle:

Plugs are gaped @ .030"

Whats the cap going to do?

filter the tach signal a bit, it's all the rage.

Gave up on the scanner, how bout a photo?
