I know the specs of the Delta 206...... same as stock specs, except with a 206 intake duration. I do a lot of busienss with Ken and Scott, and they used the Delta 206 results to come up with the Ford Delta 206...... The increase was 11% over stock..... they have sold A LOT of those...

If you have the camshaft in question, and its not running for another 2 months you can easily settle this. Pull your camshaft out, take/send it to a grinder, and have them run a cam card. That will reveal EVERYTHING about the camshaft....

You can get 500hp with a tuner on a D-max... no clue why they would call BS, but I don't spend time in the D-max forum.. (yet... I'm starting an LB7 drag project soon) As for a 700hp 5.9... thats a bit of a stretch... 550-600 is doable with intake, exhaust, and a smarty. I think you and I are...

Go post up on CompD and tell them you have a 500hp IDI... but you don't have an engine dyno, a chassis dyno, or any power measuring device to back up this claim..... however, you did some math on it.... and this is what you're making. Let me know how that goes. That's my point. A dyno...

Oh you missed my introduction thread? I only have 20 some posts, how hard is it to search? Just for you, I have a 6.9 IDI. My baseline pull was 292rwhp/614rwtq on fuel only. I have a methanol injection kit as well, but did not run with it, as I was only interested in fuel numbers. Both...

Your entire post is accurate, I don't dispute it at all.... but you aren't going to dyno on the same dyno twice and make 200hp less. This generally happens when going from a mustang to a land & sea, or a dyno jet to a mustang... ect. It has to do with tuning parameters of the dyno, one is an...

there is a difference between not openly posting cam specs, and not giving proof of your claims. every person that has purchased one of the turbo cams I came up with, got a cam card, its called facts. I'm not going to openly post the specs for someone to just call another grinder to try and...

Racin' and myself have every intention on going to Ellensburg to check this stuff out... and I personally have a real, dyno proven 400hp/800tq IDI, so I'm probably the perfect 'test subject' to judge this thing. I personally am looking forward to it. As I said, I don't have it out for Bill, I...

I am easily as knowledgeable as Bill Heath.... him and I have personally spoken on the phone on different occasions.....and I have a more powerful IDI than him, with proven dyno numbers. So I get a little annoyed at FALSE CLAIMS.

and before anyone that knows, busts my balls... all that being said, no... I don't give out the specs on my cam, nor does delta.... likely for the same reason Heath wont on his... because he knows it can easily be replicated. Its protecting your R&D. So in that aspect, I can understand his...

also, I don't want to sound like I have it out for Heath Diesel, because I don't..... but when I first heard about the 500hp IDI I was pretty excited. Then when I found out his 500hp claim is crank power, not wheel power, and its calculated, not dynoed, I was pretty disappointed. Its hard to...

I have a little experience with camshafts. I designed the 'turbo cam' for the Ford IDI. I called my grinder, which happens to be Delta, to get stock specs on your GM cams, and clearances. I can tell you this, there is nothing heath can do, with those cams, to out perform a delta re-grind.

Actually, I was already thinking about that. Then I'll let him take a ride in my IDI.....

I think Bill, and anyone else coming up with power claims without a dyno is as good as lying. Its cheap and easy to do, just dyno it.... otherwise its worthless.

these are our 3 cups: left is the 7.3 - 21.5:1CR , middle is the 84+ 6.9 22.5:1CR , right is the early 83 6.9 20.7:1CR the 7.3 cup is 20.42cc's, the middle 6.9 cup is 18.34cc's, and I've never had my hands on the far right. Highest powered IDI's are running the middle cup.

That's very small. sounds like you may just be plagued by a poor mix of parts. I thought us IH guys had it rough. I would still love to know the pre-cup volumes just for comparisons sake, as well as your standard power outputs, with what amount of fuel. I keep looking around and see some of...

I understand this, but 5yrs of information doesn't change the physics of how our IDIs work. In our IDI's, the cups are pre-combustion chambers. Injection occurs near the top of the compression stroke, only part of the fuel is burnt in the pre-combustion chamber because of the limited amount of...
