First of all I'd like to thank Ed and the guys at Balanced Performance (number's on the chart ) for all of the good work. Ed let my friend (ITR owner) and I pick his brain while he tuned my V-AFC, etc.

Here's a few pics of my car strapped down:







Well first of all my set-up is as follows:

1998 USDM B18C5 - 100% STOCK. 60K miles
AEM CAI for 99-00 Civic Si
DC JDM 4-1 Header (2.5'' collector)
CarSound 2.5'' Cat
Tanabe Super Medallion Racing Spec exhaust for 1992-1995 Civic hatch
Skunk 2 cam gears
B&M FPR
Kenji-Spec P28
Freshly Installed V-AFC
Fresh Ooil Change - Mobil 1 5W30 Synthetic

My old baseline before the header/cat combo was 175whp and 122 torque, but had HORRIBLE low and mid - HORRIBLE!

So here's the new baseline vs. tuned chart:



So what do you guys think? Notice how shitty the A/F readings were pre-V-AFC and FPR tuning? 15:1? Yikes!

Ed basically fattened the entire curve up with the FPR and then trimmed back the rich parts with the V-AFC. The results speak for themselves. Look at those HUGE midrange gains! I mean there's like +20 whp and +20 ft/lbs. of torque in some areas!

Driving the car sure is different too. Where there used to be a dip from 5000-6500rpm now there's a strong, fat-*** torque and hp gain. I can shift at a lowly 8000rpm and not have to worry about that big-*** dead spot I had before.



Peak numbers?

Well peak isn't the **** anyways, but IMO 176 isn't bad for what I have and the torque is crazy. I could not believe I'm .2 off of 130 torque to the wheels. I've seen some cammed motors not put too much over my torque readings even after tuning.



Lastly here's a video of one of the pulls - it was taken with my Fuji Finepix 3800 Diggy Camra, so it;s in .avi format and not the best diggy camcorder quality.

RIGHT CLICK SAVE AS PLEASE!!! ...or else I'll have to pull the link for bogging the Wee-Todds y0!

Oh and I'm coming straight back to the dyno next week for the results after the electric waterpump install.

Comments are welcome!

 

nice. i was wondering how much a VAFC tune would cost without hookups?

 

Very nice numbers, Tom! Biotch!!

 

very nice charts quick question, do you think it would be worth upgrading to a hondata, if i already have a vafc & safc(dont ask me y i have both, the S was free)? or should i just get my afc'S retuned? i just put a different head on recently and am currently debating.

nice numbers again

 

Very nice numbers...I am very jealous...as usual

 

damn, the torque curve really fattened up in the middle. nice.

 

nice numbers and nice car
downloadin the vid now

 

Same here, dsl owns.

Good work Tom.

 

dude your in VA? get a hondata, and give to sakai, here is his website, http://www.sgt-racing.com he's also on h-t tooo...

 

dude, sick numbers....basically stock c5 too.... you plan on doin anything else to the motor?

 

Man, your car is always so clean. Go put and get it dirty for a change.
Oh, and nice numbers.

 

Nice to hear you finally got that biotch installed, and tuned, it helped a lot as I can see. Congrats.

 

thanks- he was actually on the top of my list,im seriously thinking about going there, i would like to contact him sometime later this month or next, when i have just a little more money about his costs and fees...you dont by any chance know how much his costs are do you?

 

Hopefully you'll be hitting 12's now Tom.

 

Nice run, Tom.

 

Nice. You can hardly hear the changeover.

 

sweeet!

 

whats the story on electric water pumps? how much power are you expecting to free up and how much will the unit run you?

lol, i almost forgot to compliment you on your car... that machine is sick, nice job. did you get a new fd yet?

Can't say anything about the waterpump until it's done. In theory it should free up power lost from having to spin the impeelers on the aterpump that push over a gallon of coolant through the colling system.

I cannot even speculate at this point. The dyno operator was saying that +10 would not be an unreasonable target, but that's pushing it IMO - we'll see mext week.

 

wow, 10hp is serious, good luck and we will be looking forward to the results. thanks

 

How do you control the water pump? I remember somebody saying that their pump was flowing too much, not allowing the engine to warm up.

 

What size piping is your exhaust? any bottlenecks? It seems like you should be 180 if not alittle more, but hey that is damn nice numbers still

I would have hated to see the before midrange power if you think 20hp in some areas

This one isn't like the Mazier pump like my friend installed and removd from his ITR for being a pile of ****.

This one will have a variable flowrate and will also have an electronic box to control the engine temperature.

You can leave it on after the car is shut off to keep coolant flowing through the engine to reduce heat in the engine after shutdown. The engine gets really hot as the heat tried to escape the engine bay after shutdown.

Trust me I'll have a HUGE topic about this next week once the pump is done. Flop or fly I'll let you all know ASAP!

 

I'm sure 180whp is totally attainable at the compromise of torque and/or midrange power. To me 4whp to make it nice round 180 isn't as important as the fat-*** mid power and torque that I ended up with.

 

This sure beats the usual, "Look at my Spoon filter" thread...

We need more posts like this.
