Also - Bret any news on my buddies 383? I hear the head choice is now trickflow? Either way I am sure it will be a nasty setup
Ken is going to run some 42's but on a head cam car I would like to see at least 36's to have enough fuel. It's going to be interesting to see the tuning tables on this since the midrange will need more fuel this time.

Yeah we are doing some TFS heads for that setup with a LT intake for now.

That's not worth $2000 in my book. That's not worth $1000 in my book, nitrous doesn't cost that much, and there's a lot more to gain than 40hp.

Welding wire and plated aluminum doesn't cost that much either.

just my .02

D Moss,
There is nearly three weeks in the construction of that intake, probably over 100 hours of design work and after it was designed the thing took two weeks to build. I feel it is a VERY fair price tag, not to mention when you get to thelevel where you need one of these your only choice is a carbureted intake converted (keep in mind you will have every ibt of 1800.00 in that setup by the time it runs) or a 3000.00+ sheetmetal intake from Hogans or the like. I think you should think it out a little more, this thing will be a "bolt on situation" when its done requiring no modification to the cables or even deletion of the cruise control.

So to make sure I understand the post correctly, this intake, when finished, will be able to bolt on to any LT1 head, and LT4 for $200 more, and will offer nice gains over the stock or even what a ported LT4 could do, correct? Sounds interesting if so.

I would charge somewhere in the neighborhood of $3,500 for a single throttle body custom manifold including fuel rails, developed from the ground up. Figure in options like nitrous bungs and burst panels for the guys who may need them and the price keeps climbing. Do you want aluminum or carbon fiber? Cost goes up accordingly.
Being a true custom, the design would be tailored to the customers needs and development would take place on a per customer basis. Plenum volume, runner volume, injector targeting, taper and trajectory all designed to a specific end.

$1,800 for an intake built on the factory casting is a very fair price as I see it. I couldn't do it for that considering the true demand.

A show of hands for those serious enough to purchase an intake like this -the ones Bret and Bryan are developing- would satiate my curiosity. Any takers?

Good luck to you guys.

I'm definitely looking at it. Once some solid numbers/real world performance figures come out, I can say that most likely I'd be in on one.

Hey look it's Chuck How ya doing?

Well I am the guinea pig on this one i guess, so I think there will be a lot more intrest once I get some #s.

Edit- Chuck you are 8 days shy of your last posting a year ago. So you just like stopping by in June apparently?

Absolutely right. Its about time us LTx guys are on our way to having a quality intake available besides hacking up the stock intake. Between $1k-$2k for an intake? I dont think too many of us will mind...I know I wont.

Earlier in this thread there was mention of the monoblade/58mm TB being the way to go. Would that be completely necessary? I got myself a 52mm to prepare for my heads/cam setup coming this winter and am very much so interested this intake.

Ken...you're Bret's guinea pig, and I'm Bryan's. I hope we both run faster...I anticipate we will.


Chuck...nice to see you. You've been missed!

I am impressed to see you stop by again, it's takes one hell of a post to get this guy out.

This is one of the guys to go to if you want a full sheet metal intake, or even better carbon fibre which I would love to use on a LS1 intake setup. I'm guessing you have probably do more carbon than Wilson does, but then again Wilsons sheetmetal is not cheap.

I'm sure you are building the runners out of Al block and CNCing them to the dimensions you need externally and internally. I would love to have that option, but then again I try to make things as simple as possible to get what I am after, not with the factory casting here, but a SBC one.

Bob, thank you.

Mr. Mook,
What can I say, when it gets too hot here in Texas I start looking for alternatives to yard work, the garage, work-work! and outdoor activities in general. So I brush the dust of the computer, reopen all the cancelled accounts and check out Camaro z28.com.

I don't want to lie to you. I do a great deal lurking in between, so the date is purely coincidental. Never know when something interesting is going to pop up.

I'm happy to see that there is some interest. I figured this market for dead here a year ago with everyone shifting their attention to the LS1.

The results should speak for themselves. So lets wait and see.

Take care

Whoops.

I'm a slow typer and the fact that I'm eating a taco while trying to get this out didn't help me get my response before yours Bret.

You are correct, I like to work with carbon fiber. The intake on my sb2, dual plenum dual throttle body, is probably 90% cf. Great stuff to protoptype with if you have the capabilities. Cost is a factor but for structures which are not necessarily high stress, you can build them for quite a bit less cost.

Yes sir, I build the runners from a billet and join the two halves for a custom runner configuration. Works very well and ensures that you have exactly the right port design you were after. Usually using a stereolith model for the master. But there are many ways to do it. If you have 5-axis capabilities, machining the complete runner from the billet is not terribly difficult. No only that, you insure the accuracy of the injector targeting by machining that in at the same time.

Take care

Nice now I get to answer questions.....

SB2 dual plenum, dual TB... did you connect the two halves at all? A lot like the Viper Intake. Understandable why you did the dual plenum, it helps the low RPM TQ correct?

How about the fact of running a non carb style setup with those heads, I presume your intake has the TB's in the front so does this cause any problems or do you tilt the runners to work with the ports, or are the ports done in a way which works with the intake rather than a single plane.

What do you think about using fiberglass cloth like CF? OldSStroker built a nice soap box car for me in 89' out of wood and glass cloth like a wood strip canoe, it's one pretty car. I would think that glass would work just as well with epoxy as the bonding agent, but is it strong enough? I'm not as worried about wieght as I am about thermal conductivity and ease of manufacture (for 8 runners)

I wish I could have a 5 axis in the shop for just that. I saw a Wilson 4.6 Mod intake a while ago with the runners done like this and thought that was a awesome idea. Each runner was one piece with the outside and inside profiled by CNC, I should have taken a picture of that. Another plus is that you could have the runners removeable to test different port designs.

I agree.

It's also good to see that R&D for the LT1/4 isn't totally dead.

Raising my right hand now, as I am a proponent of N/A motors, I would purchase one. Where do I sign up?
