New intake for crossfire = more HP!!!!

[boomdriver]

When you buzz an engine faster, it automatically makes more horsepower at that higher rpm. With it's superior breathing above 4000 rpm, the Renegade makes a lot more horsepower above 4000 rpm. I have no idea how well it will perform at the extreme bottom end until I get mine on and test it. As my 700R4 has such a low 1st gear and the tach ends up at around 2800 rpm after my full throttle 1-2 shift is made, I'm expecting I will lose very little bottom end. When I'm cruising around at only 1500-1800 rpm, I will likely lose some torque at those real low rpms. But I really don't care as I want better performance higher up the rpm scale.

No, thats not true.

Spinning an old TBI up to 6000 will likely end the discussion anyway....

The more that I read this the more that I see someone trying to avoid accepting the reality that they lost their money on a scam;help .
This "new" intake design is the crossfire equivilent to the air-foil in a TPI throttle body. Junk science with good marketing. fact of the matter is that the money is already gone...

What makes you think I have lost my money? And by the way, I spun my Crossfire up to 6500 rpm in 1st gear just a few days ago and it didn't come apart. I didn't intend for it to rev that high though. I'm recalibrating my governor and that's why it revved so high. I'm shooting for a 1-2 up-shift at around 5500 rpm. I think the spool in the governor might have a burr on it and it got hung up. So in the next couple of days I'm going to take it apart and work the spool over with fine lapping compound to ensure free motion within it's bore. But back to my question. Why do you think I have lost my money? According to DCS's last update on 3-22-10, they're saying they are almost ready to go into full production. I would imagine that will start within the next two weeks. Several test manifolds were cast at the beginning of this week and they will be sent to several people as soon as they get machined, boxed, and sent. So things ARE happening!

 

[boomdriver]

well lets see..., you already paid. Over a year ago?

What did they send you for the $400+ ???? Or did UPS just keep on cruisin when they came by your place?

maybe stating that you lost your money was a bit harsh. Lets just go with missing.

Anything is possible but it's not over until the fat lady sings. And I think the fat lady is going to start screaming her guts out within the next two weeks. I'm quite sure my money (and everyone else's) is being used to pay for the tooling costs and labor while this manifold is being developed. I'm very sure I will get my manifold, but I expect only a few will end up being sold. There's just not that much interest in these old Crossfires anymore, and it appears most owners have replaced the Crossfire with either a carb or updated it to a multiport fuel injection system. I'm told I am #7 on their pre-buy list, so I will be getting one of the very first ones. And I think nelson84 is #5, so he will get one of the very first ones as well. As nice touch, the manifolds are going to be stamped with a serial number.

I do hope it works out for all the folks on the pre-buy list.

Years ago, I had looked at an SY1 conversion for a crossram set up on my '80 Vette. I had visions of using a heavily modded system... but changed up and went with a modded SLP/TPI system.

I'm afraid I don't know what you're talking about. What is a SY1 conversion? And then what is a SLP/TPI system?

The SY1 is an old school crossram set up for dual fours or whatever the top of the box had- some were even single fours. Lots of folks have taken them and made them work for a crossfire.

Here's one set up for crossfire...

As for SLP/TPI... that was a Tuned Port Injection (L98) set up using siamesed runners offered by Street Legal Performance.

Oh, a Smokey Ram. Okay, now I know what you're talking about.

The Renegade

For those of you who don't know, the Renegade is simply a Crossfire with full size 20% tapered runners and a 20% larger plenum. It will look just like a stock Crossfire as the EGR valve is mounted in the exact same location. That's it. Nothing new; just made like it should have been made. But as the runners are much larger, it will flow in excess of 1000 cfm; double of what a Crossfire would flow.

 

[nelson84]

You guys are busy on here. I don't understand what all the talk is about, the renegade is almost done and they will be sending out a few intakes to select customers and we should all have our intakes in about 2 weeks. How hard is that to understand?

The people who don't own Crossfires don't really know what this is all about. But for those of us who DO own Crossfires, we know all too well the Crossfire's breathing limitations. They fall flat on their faces at 4000 rpm because of their tiny restricted runners. That's the whole reason behind the Renegade. The Renegade is simply a high flowing Crossfire Injection manifold that has had about 20% more plenum area added to it. And as it was designed to be a bolt-on replacement for the Crossfire, it has an EGR mount in the exact same location. It is also the exact same height as the Crossfire, so the OEM air cleaner will bolt right on without any hood clearance issues. For us California residents who are still bound by California's tough smog laws, it is a dream come true. With the Renegade, our old L83's can finally kick butt on the later TPI cars.

Let me get this straight,this thread has been going on for a year and a half and you still don't have your new intake yet? That would raise some serious red flags for me.

P.S. I happen to like Dave Emmanuel.

Thanks for the clarification. I stumbled on to this Thread yesterday and found it hard to believe that you guys haven't seen your intakes yet.
Dave Emanuel is very outspoken author/writer who writes a monthy article in Corvette Fever magazine. He was mentioned in a couple posts in the first pages of this thread.

If you'll read the DCS updates, it's real obvious why this project has taken so stinking long. DCS is trying to run a business and trying to get their Renegade designed/built at the same time. They have to deal with their tooling maker, their machine shop, and the foundry all at the same time. It takes a LONG time to get a project like this going. When several test manifolds are cast, it may be days to weeks before the machine shop can machine them. Then if any changes are needed, the tooling maker has to re-design some things then wait for the foundry to cast a few more. And then wait for the machine shop to machine those new castings. So nothing happens fast when you're trying to get a project like this going. But I'm told DCS is almost ready to go into production. I would venture to guess within the next two weeks.

 

[toobroketoretire]

People on standby

Remember, nobody is sitting around waiting for work to come their way. The machine shop has work to do all the time. So does the foundry. So just because new tooling is delivered to the foundry, it doesn't mean the foundry can jump right on it and cast some manifolds that day. Uh uh. It might be days or weeks before the foundry can cast some more test manifolds. Then when those test manifolds get delivered to the machine shop, it may be days or weeks before they can machine those test manifolds. If any changes need to be made, the whole process starts all over again. Re-design, cast, machine. Then re-design, cast, machine. And so on until everything is coming out exactly right. DCS has finally gone as far as they can go and it looks like the production will start real soon. DCS announced their pre-buy around March 22nd 2009, and I think the one year we've waited for these manifolds to get designed is very reasonable.

 

[catbert]

I'd also add that when catbert and Hib are in agreement on something... its likely to be true for sure!

Wait a minute! I agree with Hib a lot - not as much as Hib agrees with Hib, but a lot.

 

[nelson84]

Any news yet on the intakes? Or is this week shot because of Easter?:confused

Yeah, I would imagine things will slow down during the Easter holiday and further delay the Renegade. After the recent pours of some test manifolds, DCS is going to give a few samples to selected people. In the meantime I would think the work is continuing on the development of the Renegade. From what they're saying in their last 3-22-10 update, they're almost ready to start full scale production. But I have a feeling it'll be at least May before we get ours. I wonder how DCS is determining who gets these early ones? I'd sure like to have one if it doesn't have any issues.

I would think they would start at the top of the list and work down. Have they asked you for your shipping address yet?

No they haven't asked but I sent my address to them about a month ago. Long before they announced they were releasing some manifolds early. I was told I'm #7 on their pre-buy list in the very beginning and they're probably going to send out 6 of them. That would be my luck. But there's the very real possibility some of the very early pre-buyers before us may have backed out of the deal; maybe losing their patience or selling their cars, or? So we might have gotten bumped up on their list. I sure hope so anyway.

 

[ex-x-fire]

The way you guys are talking about delivery dates, I'd be out there removing the manifold & scrapin old gaskets.
