Does anybody have any experience with DH racing Throttle bodies. Im having issues with my skunk2 68mm. Just wanna know if anbody has one or has seen one on someones car. (with good idle)I cant get my car to idle below 1100 rpm. It shuts off.

Are you running a standalone engine management? You can fix the idle issue with a standalone. I don't think that changing the TB will help you at all. Idle is controlled by the IAC system. With proper engine management, you can adjust the IAC duty cycle and set your target idle properly.
You may also have an issue with intake leaks. An improper installation or something not connected will lead to idle problems. Does the Skunk2 use the stock IAC valve?
I run an AEM EMS UEGO. I first droppped the car off with the tuner. (ASE Certified Master Technician also an AEM Trained and certified tuner. He is the best around this area. He tried and tried and stated its because of the TB. His suggestion was to apply a stock TB. My setup is too agressive for a stock TB. At least I think so. I cant get a consistent idle with this darn thing. Sometimes the idle will stick. Sometimes the car just shuts off. I cant get the car to idle below 1100 rpm which is really a pain. Ive been tooling wiht AEM with direction from a friend and we have got it a little better from where it was but still the problems exist. My set up is below.......is there anything else that stands out that could be causing this problem? Yes the stock IAC valve is used. I cleaned it pretty well.

Wow that's really weird. The reason I say it is the IAC valve is that idle air has nothing to do with the throttle body main inlet. At idle, the throttle plate is completely shut (unless there are leaks or problems with the throttle cable). Air comes in through special small passages through sides of the TB. The IAC solenoid controls how much air gets let in through these idle passages.
If Skunk2 does something different or the gasket sealing the TB to the IM is bad, it could cause air leak issues. I think it would be at least worth removing the TB and inspecting it for problems. I would also make completely sure you have no uncapped ports on your IM or other air leaks.
All that being said, I think Skunk2 products are all crappy. It could just be bad or defective product design.
Have you tried a stock TB to see how it idles? That way you know for sure it's the TB.

I sold my stock Tb. What an idiot I am. This actually my second TB from Skunk2. The first one had a binding issue. So Its hard to tell. I do need to find a stock Tb to put on this car for diagnostic purposes.
Hello I’m going to but my foot in my own ass here guys so here it goes...
so we all know that I have been a big supporter of DH-Racing... most of my work is don’t by them... well where do I start... every part I have received from them is garbage and a rip off and promises of parts that are supposed to be there that aren’t...
My head was supposed to be ported and polished and it was... halfway...
My block was supposed to be bored over to a 2.3L and sleeved with bigger pistons... block is unsleved with STOCK pistons not bored....
I found all this out when I took my car to be tuned and this is what they discovered I should have been smart enough to catch it myself but I didn’t really know anything about the pistons and what the block should look like...
Bottom line is his a lier he ripped me off of thousands of dollars and now doesn’t answer my phone calls...
so if anyone is thinking about buying ANYTHING from DH-Racing I’m tell you to go somewhere else he will just give you bull**** and false hope and lie and you won’t get what you ordered...
I’m a dumbass and now I’m ****** I know....
if you post anywhere elce or know somone thinking about anything DH dont let them do it spread the word and lets put his ass out of bisness so this dont happen to anyone elce...
so you made an account just to pull up an old thread? Dave has worked with me since last August of 07 on some really radical stuff for the h22. Yes his work takes some time..so does any other shop who is worth anything on the import scene. If you really feel like you got ripped off, keep calling him and get it fixed. Why dont you take some pictures of this "halfway" port and polish and the unsleeved block and let us see what was done wrong
you know i would love to except the ****s alredy put together. i have been working with him forthe past 2-3 years and he acts like hes your friend and hes gonna give you this and that a promices you this and what you get is half if you can get him to give you anything at all. and its alwes oh man i got this new thing more money this more money that. im sure you know if you have been working with him... i created an account so i could tell people so no one elce makes the mistake of buying anything from him again hes a joke.
So take it apart dude, why did you install an unfinished product? Why didnt you take pictures of it all then? So you are saying you driving around with some passages ported but others not? You are slandering him dude, and all I can say is good things about the same guy who willing jumped in with his fab shop for several of my projects and also rigged up some things for the school's chemistry research team here.
As a consumer if he really did rip you off then you were stupid to install the products. I've gone through a dozen different manifolds and about 6 different res kits with him each time test fitting them, and wanting a change to the design and sure enough 10 business days each time arrived at the PO for pick up. How do we know you didnt just go to a real novice tuner/install shop and they were just pulling your leg trying to make you be more interested in their products? /thread

Unless you have more proof, I would keep things quiet. We all have opinions and some bad experiences, but your need more proof.

who uses cast pistions in a all motor build? yeah i got thous dule TBs, there a joke you should see the system... and when i did ask dave about the ports he said "dont worry about it, its a trick"... so no this is what i get for trusting him and actuly thinking his work is good... i didnt know any better i never built a engine or ported a head let alone seen one so i didnt know the diffrence.
go ahead learn the hard way like i did... you should know that its alwes hey i got this or hey you need this he alwes trying to get more money out of you and im sure you know that, and dont think for a second he is your friend cause he just wants your money.
dude you keep mouthing off and still we see no pictures. Every other valid complaint i've seen against a race shop has been well documented with pictures and emails - where are yours? Those dual tbs once you learn to spell the things you are claiming to have are off a prototype h22 build, we established a long time ago would take 2 IMS to run things properly without having conflicting air flows.
Get some pictures up of your horrible work if you really expect some to receive any credibility
then you have no credibility, and now you're cursing at me. You proved my point, no proof no credible complaint kid, grow up and be on your way. Still real dumb of you to put on an unfinished head port and run it, if that's really the case. You could atleast take pictures of your dual TB setup if you really have it - let's see something geeze
yea, just talked with Dave, he has only sold 3 dual tb setups so far, the only person and I have documentation to provide if you really want to push this kid, only one person has bought them AND head work, none have had block work. So I'm calling you out now, Dave is a one man fabricator and shop worker, period that's why he takes time but everything comes with warrantys and has done many sends and send backs over the time with me.
Here is the cell # for him, if you really got a legit case call him he's waiting on a call from you: 702-788-1327
Let's try to keep this civil guys. Rather than profanity, name calling, and a pissing match. Let's use etiquette and some factual basis for discussion.

i have his cell and he never answers work or cell..
yeah this was my second head from him because the first one i had from him broke a valve with in 3 months. made me pay 1500 for the second one and it was half assed if that.
DH is garbage
here you go buddy heres the tb set up he sold me...
if you look on the manifold here (dave ported) look how big #1 is and shiny and the rest are half assed. look like they where just tuched to look like they where worked on again he used the "its a trick dont worry about it" excause.
a better look
From my first head from dave
and like i said the valve broke and dave admited he used crapy comp tech valves or whater he used and said they where week and made me pay 1500 for a new ****tyer head.
heres the setup with tbs and new head on my car just so you cant say thous arent my pictures.
yep bottom end is garbage they put my car on the dyno yesterday and it only made 210whp (whitch was less then just the head he sold me befor made with stock block) and was blowing smoke like a mother because the cylinder walls are scratched. needs to be rebult.
warrantys huh? ok tell him to send me a check for 7500$ for a new head and block.
DH is garbage anyone is dumb to buy anything from him.
so as they tear my **** up ill post pictures of the ****ty block i was sold.

The intake manifold looks fine to me. You can't make any judgements about quality from those pics.
As far as the valves, what were you doing when the head took a dump?
you joking right? look how big the #1 runner is and look at the rest.
As for what i was doing when it broke. i down shifted into 2nd gear @about 4000 rpm. he says there good for 10000 rpm and can take anything you through at them... except a down shift i guess... garbage...

LOL whoops. I didn't pay close enough attention. Yea, that's a big problem. DH gave it to you like that??

Were the valves supertech or "comptech"? Comptech I've never heard of, so God knows what they are like. Supertech on the other hand are just fine. Not the highest end, but they definitely won't cause a motor failure.
send it back to him, he'll fix it up
Never seen work that trashy come from any company, you have my apologize now that you've posted pics. Call up cell, he just got his new one and always picks up when I call about something.
However, on the IM, they are not all made to look the same in size nor inner dimensions...that would defeat the purpose of proper porting, at any rate, get that head redone, looks like a mess
