***UPDATED ADDED VIDEO - look below***


I finally got my Neptune ECU installed and dyno tuned by Cortney Green in the snowy state of Utah.

We did a total 27 or 28 dyno runs, tuning pump gas and race gas maps. We used a p28 vtec ecu, with vtec enabled even though i have a non-vtec motor. We swap over to the vtec maps at 5000rpms. The vtec maps can run better timing and have much better fuel resultion.

We couldnt get the my boost any higher then 24psi - and even at 24psi the boost was falling off on the topend (you can see it in the dyno plot below - look at the difference between the pump gas and race gas map - the pump gas map keeps building power while my race gas dyno just falls off). I was hoping to break 400whp but we couldnt get the boost high enough. We figured at 32psi we would of put down 470whp. Next time!

I put down 330whp and 240torque on 91 octane pump gas at 20psi. And 380whp and 280 torque at 24psi on 112octane race gas. Im not super happy with the race gas output because we couldnt get the boost any higher. But 330whp on pump gas is awesome!!

327whp 239 torque @ 20psi on 91 octane pump gas


369whp 279 torque @ 23-24psi on 112 octane race gas (the best looking highboost dyno we made)


old engine pix - ive since cleaned up all the loose wires and hoses.

Glad to hear everything worked out and you made it home safely... Congrats man...

Cortney told me he was using the vtec maps because he was expecting to tune above 8000rpm... You guys decided not to go above 8?

 

Awesome! Feel free to post this on http://neptune.evans-tuning.com in the NepTune'd forum.

Get that 5 bar goin!

 

another monster tuned by Cort!!!! Good job man and nice setup!!!

 

ZC? Wow.................

 

nice

 

holy ****.

it's like a mini LS-Turbo with some serious power.

that thing must haul some mother ******* ***

props on another savage d series.

 

Get some video of that haus on pump gas. I wanna see what she does on the street. Awesome setup. Love the manifold.

 

Thats sick.

How many people are tuning Neptune now? I thought it was just Full-Race and Boosted-Hybrid but I haven't been paying much attention.

 

more shops are starting to get it . i agree , we need a vid of this mother ****** in action.

 

Jebus! On a ZC? Looks good. I love Neptune.

 

Props on a great numbers. I stopped by there just after your last dyno run with some friends. Its cool to see something different and with great success.

When do you plan on coming back to re-tune? And have you been able to figure out yet why you're not making more boost?

 

cant wait for a vid

 

great to see neptune in action.

 

congrats

u got a full exhaust or hwo did u routed the exhaust

 

I want 380whp

 

my pics from that night
all i have to say is WOW, that thing sounded crazy, open downpipe

liam, it was great meeting you, hopefully iw ill see ya next time ya stop by haha.

Is it just me, the angle, or...does the pipe that come of the external wastegate stick out through the hood??? I hope i'm seeing things....if not...that's ******* awesome


EDIT: ok, weird, first set of pics, no pipe on wastegate, then second pic., when it was on the dyno there is a pipe of the wastegate, so i know i'm not seein ****....i need info....lol.

 

It was just on there temporarily for the tune. Last dyno I saw there, they used a flew pipe on the wastegate, and it would rise as the motor reved. It wsa pretty funny.

 

congrats on the tune man i was suppose to be there helping court pull all the **** out my car for the cage im sure you saw that hell hole project
but good luck with the zc
