Last friday my friends and I headed out to Balanced Performance in Sugar Hills, GA for a dyno tune as well as the Nopi Nationals. For any of you that are looking for a GREAT dyno tuner, I highly recommend Ed at Balanced. He does a great job and he is more then happier to sit down and show you how the tuning process goes. I would also like to state to the people out there that want '400whp' that it requires a LOT more then just buying pistons, sleeves, rods, and a 60-1 turbo. Plan on putting your blood sweat and tears into your project and always expect the unexpected. Or you can always pay someone to do it for you... but you do not get the satisfaction of knowing that YOU did it yourself.

With that out of the way... The car was tuned on race gas for 20psi. For those of you that want high horsepower h series motors, i do not recommend running 93 octane above 375-390whp. This would be due to the mean specific brake consumption (msbc) of the h series motor as well as trying to avoid detonation. Around the 390whp mark we encountered a small misfire. So we then decided to add some 103 octane as well as gap the plugs from a .028 to a .025. First run after that increased 20whp. I originally planned on running straight 116 octane right around 25psi or so, but we decided to call it quits since our group was there from 10am-5pm. Maximum power was 423.3whp and 360 torque at 20psi. This was with relatively low timing and without even playing with cam gear settings. I could have squeezed a bit more power (450-475whp level) by advancing the timing, running 116 octane, and playing with the cam settings but we decided to stop while we were ahead. Plus, the rubber 90deg boot popped off everynow and then under the 20psi pulls. That will be soon solved by adding a 90 deg elbow welded to the compressor of the turbo in the near future.

-not the best video in the world, but it will do for now. I wish I would have taken more video's with my camera but I was paying more attention to the tuning process as well as monitoring the dynojet programs.

Special thanks-

Mike at MotorMatrix.com
Integra707 for the IC
XES for all of his help and pointers
All of the Prelude and Forced Induction guys who have helped me out greatly

In the future to come-

Yea, too bad its a H23A1, huh?

 

Wow very nice lude!!!!

 

very very nice

 

nice

 

Very nice!! Did you relocate the battery to the trunk?? I want to do that.

Man, I missed you at NOPI!!!

 

Yep, the battery is located in the trunk. I am going to order a battery box with a kill switch from summit in the near future so I am allowed to drag race it. I will also be adding a roll cage in the near future as well.

Maybe we'll meet up next year, haha

 

god damn, thats some crazy numbers.

beautiful engine!

 

all I can say is

 

wow man that is awesome.

 

WOW!!!!!!! u have done an excellent job!!!!! keep it up.

im gessing u havent hit the track recently? or have u? get us some times up here

keep up the good work man.

 

holy **** those are some BADASS numbers on an h23a1 dude, how much cash was put into that bad boy and how many hours?

 

all i can say is holy shizzle mah nizzle!!!!!

 

out of curiousity, did you do anything to the drive train, such as upgraded axels etc? Just curious if you didn't do you think the stock CV's and other parts are going to take 430hp with slicks? I know alot of the honda drive train (ok well tranny) are damn good, just wondering which parts and how good.

 

not to sound like a noob, but what is that big light blue thing in the engine bay...?

 

i think thats a fan to cool off the engine. and no it's not a mod.

 

it's not to cool off the engine, it's a working fan, just cools you down while you're working lol, the matco guy sells them, they're called blue something or others, they're work fans

 

very nice, i wish i had your dedication

well, close enough.

 

heh, did you see the civic that put down 438 on the mustang dyno with the tires losing traction?

what kind of axles are you using?

 

You and XES are my h23 heros!!

I didn't know Will hooked you up with the IC...Integra707

 

No I have not had a chance to make it out to the track yet and I probably won't until I get some axles that can take the power that I'm putting down. The transmission has been rebuilt with all OEM gears/synchro's and I have also added the quaife LSD.

The 'blue thing' on the dyno is a fan used to keep intake manifold temperatures down.

 

ya... what kind of axles are u planning on getting?

 

WOW! Props to you and the H23!

BTW, at which rpm do you start seeing boost? Or full boost?

Excellent job, like always!
