BlinkerFluid's 96 Eclipse GSX *Long read, well worth the time*

[BlinkerFluid]

Sep 2011

Alright guys, if you haven't seen on facebook by now, I was on Derek's dyno Friday night for some after hours shop fun.

I think Derek will attest to this being one of the most low drama dyno sessions ever, car wise anyhow, the dyno was another story. ;)

First pull on wastegate boost which was 33psi dropping to 32 gave us a nice 725HP. The datalog looked great so I bumped the boost up a half turn. The next run was 825HP ish IIRC at 37psi. The next run was 40psi. and 873HP.

I shut the car down and checked the plugs, they looked great. Fired it back up and 42psi dropping to 41 gave me 897HP. Turned the boost up some more and it made 43 dropping to 42 for 918HP 600TQ. At this point even though I had met the goal I set after pull #3, the car was working so well I decided to keep going with the boost.

Instead of going up 1 or 2psi. it actually dropped off a little and made 909HP. The next run is where it got interesting. Another small turn on the boost controller. The car just tapped 48psi and the engine acted like it had a huge load on it and RPM dropped. I thought the engine came apart. It still idled. I looked to Derek and he pointed out the screen of the dyno. "Reduce torque immediately," flashed on the screen.

Derek said he saw 650TQ before the shutdown, that was 50lb/f over what it made on the 918HP run. There went the 4 digit dyno run at IMW. When the program shut down it also deleted the 918HP run, though Brandon had gotten it on video.

I decided to turn the boost down and try to sneak up on the dyno's limit. The next run boost came back down below 43psi. for another 909HP run. Back up a little on the boost controller, midway through the next pull the car just unloaded and sat on the limiter that I had turned down to 9250RPM. Erb said he saw fire from under the engine and I thought the transission or an axle broke.

Further investigation showed that the left pod had eaten it's optical sensor and unloaded. Erb thinks the fire was from the wastegate dumps, which makes sense.

I didn't get a chance to rev above 8500RPM to see how far it carried out the power. I also didn't get a chance to try moving the cams around and see if there was any power to be had. Also, I did not change the tune on the car from my street tune. The fuel and timing maps were exactly the same when I arrived, and when I left. Not too bad IMHO.

I'll get the car back over there for the second iteration of Red Car vs. Dyno.

Here are some sheets and a nice video.

First run.


Third run.


Forth run.


Seventh run.


Eigth run.


First run vs. best run that got saved.

Thanks to Erb for all his help and to Bill and Derek for busting my balls and staying at the shop late. Marco too if his Canuckistani ass looks at this thread for getting me my manifold fast!

That sick! Nice build so unassuming with the way the car looks as well. Amazing sleeper.

This has to be one of the most amazing 2g eclipses I have ever seen.

[tooslow1]

absolute astonished by your build man

[BlinkerFluid]

Thanks.

I still can't believe how well behaved this thing was on the dyno. I just wish I got the boost up to kill (50-52psi) and spun it up to 10K RPM to see what would happen. I think there's some more power left on the table.

I had it out for a drive 2 weekends ago and still think it's fun.

Very nice, thanks for the update!!!

Wow these are definitely some of the highest if not the highest HP numbers on this site!! hope you keep enjoying the car and keep us updated... this car is awesome

Why are you using a gm maf instead of speed density?

Great **** Jesse!

The simple answer is because it works great.

I get a kick out of how well a MAF really works when you take the time to properly set it up and tune the car. It runs flawless. Starts easy, cruises at stoich AFR, transitions to boost without missing a beat, and gets 20+ MPG on E85. The past couple years I've driven it to the Ridley Creek Park DSM meet.

I really feel at this point, there is nothing to gain from speed density but headaches in getting it to do what I want it to do when it needs to do it.

All the parts are there if I need to go that way though. Just to note I am not using any of the fake MAF settings in Link.

[tooslow1]

can i get a ride in it? haha

[Vtecepidemic]

Ridiculous numbers out of a 4cyl that doesn't look crazy as ****. Def wouldn't think it had that kind of power just looking at the bay.

Awesome job though. In to see some drag videos.

What a monster! The horsepower is practically a vertical climb up in the higher rpm area. That must be a neck breaker. :D

It is, and it feels exactly like that. The boost gauge lazily rises to about 15psi, then rockets to what the boost controller is set to. It feels like nothing is happening, then BAM! Full power.

It rips the tires loose and gets to be a handful in a hurry, but I wouldn't have It any other way.

Are you back from deployment yet Jesse? Hope to see this thing out at the track this year!!

Nah Chris, still in Afghanistan. Hopefully I'll get to catch the end of the season. How has your year gone?

[11secdsm]

It's been a good season so far. 9.5 on wastegate pressure earlier this season and haven't had time to go back since. Hopefully i'll go late next week and turn the boost up. Stay safe over there.

Stay safe and thanks for your service!

Jesse I had no idea you had your build on here, so sick. One of the best and well built dsm's I've seen. Stay safe over there
