what's the purpose an idle air valve?
what is the size of our current, factory throttle body?
is our stock engine management system going to adjust well to this presumably large flow change?

Josh hit us up with a dyno chart for a d17.

Don't forget that the EVAP purge valve is also mounted to the stock throttle body.
For those of you who get this setup, it looks good - but remember this isn't going to be a great daily driver - most likely for track use.....

Rep Power: 0 I second that. Want more horsepower, but not at the expense of drivability. Why add 20-30 hp and get a poor running car. I was fully prepared to get this, and e-manage or whatever, but not if car runs like ****. More information on this would be appreciated.

Also, what about the cruise control issue, will there be an adapter available so that we can continue to use our cruise control?

the iac lets a small amount of air passed the thrttle plate when closed to control the idle and not let it bog down when the engine is under load...A/c on alt charging turning the steering wheel at idle(power steering) or when the engine is cold.

Rep Power: 0 This is what I don't want from bleek comments without knowledge behind them. This is not going to effect drivability at ALL. Very minor upgrade and just adds power and air, compensate it with fuel and that's the only difference in the routine you will see. As for the cruise control, I don't see us making anything for that, so if you see that as a downfall I apologize. Maybe in the future.

Rep Power: 0 In colder climates people need to keep those coolant lines intact. Most people down south bypass it anyway. As for the evap I took it completely off of my LS swap and have had absolutely no problems.
The only way they can prove you wrong opto is by verifying that nothing will happen through testing. Has this combo been tested on a D17?

Josh, don't get me wrong buddy. I am not ripping on DH's products - in fact I think they are cool. I am just trying to make everyone AWARE of the fact that you WILL lose creature comforts with all of the add-ons you sell - PERIOD!
- No more cruise control
- No more PS
- Reduced AC
- Reduced Alternator output
- ETC
Most of the people on this board DO NOT KNOW THAT - and when they get their car put together MAY not want to lose those comforts (I being one). I bought a civic to be my daily driver. If I wanted a drag car I would have bought something else. Make parts which allow use to keep everything else and I guarentee you will get more buisness (including mine).
As far as the IAC valve, there really wasn't a big discription about it in the manual, so I went on my best judgement - granted I'm no expert Josh, but its not fair to accuse me of not knowing anything......That's pretty petty to call my comments bleek.

Rep Power: 0 Ok we have been through this and the guys who have the pulley installed said they FELT NO DIFFERENENCE IN AC NOR PS, and added power, so that isn't true. No big deal Im not upset, but cruise control is the only thing you dont have the option of keeping with our parts.

It will be tested I believe by Guns, so lets see what happens. It will hold up for sure, lets see how he likes the power.

Rep Power: 0 It is just the same as any other manifold. The throttle body is bolted up just like normal, and the TPS works just fine, so it will work. I am just as eager to see the dyno pulls.

So it wasn't tested in-house before being released to the public? I am anxious to see a dyno chart does Guns plan on making a few pulls?

The numbers will be off for you NA guys, sorry. But you can compare my dyno with SF and see how much more hp I am making with the throtle body.

I dont know where UPS takes three days but unless you are right up the street that never happens. I sent it out, call me tomorrow, so I can give you the tracking numbers when Dave is around to get them. Thanks

Thanks for the fast reply and I will post results. There is no hurry on the heads. Take your time and have Dave work some of that VTEC magic you posted about on them

Rep Power: 0 He will for sure. The heads are sick as Mike from SF, and Melissa have said. They are going to make some serious power. Everyone I really suggest sending us your turbo manifolds or headers or having someone port match them to the HUGE port we use on our heads. This will make for a lot more flow. Also, the exhaust manifold gasket will need to me matched. I am selling exhaust manifold gaskets all matched for $50.

I dont want to pull off my turbo to send you the manifold. I just got it working and it was a biatch to get it inthere the first time.

Rep Power: 0 I would suggest doing the porting, but it's on you if something goes wrong. Just need to match the ports up a bit, so you gain the best overall power.
