I just got my FastBurn heads in, and couldn't resist mocking up how the set-up will look. Fuel rails are being fabbed as I type, then it's off to the powdercoater to have the intake and throttle body powdercoated with an "almost chrome" finish.
Heads will be off tomorrow to the head shop for upgraded springs to handle the .560 lift Lingenfelter roller - as well as pocket-porting.
Will post more pics as it comes together.

wow, I've been wordering if the RamJet intake had any restrictions, it seems not. Nice wide open chamber ports.

If you have not picked up an LS1 throttle body yet check ebay. I see them from time to time going for 50 bux. Sure beats GMs what 400 new?

Will you be using the stock TPI harness and sensors to power it?

I'm actually going to have aluminum material welded/added to the each side of the TB inlet so that I can port the inlet straight through. If you look closely at the TB inlet, there are actually airflow restrictions on either side of the opening - very similar to a TPI plenum - except that the material on the RamJet is even thinner than the tpi plenum!
I already have a new L31 Vortec TB "take-off" with TPS and IAC.
I'm using a Haltec programmable DFI and harness.

Nice...Whats the Rpm range for the Ramjet? Its shaped like the old mechanical FI vette intakes.

Inside of that intake looks like the inside of my mini ram.

How does the TB attach? All those small tapped holes???

yup, did notice those walls. Sounds like a plan.

The intake is $400 from Pace Parts.
Throttle body is an LS1 or L31 Vortec TB. I'm using a brand new takeoff L31 TB that I got with the IAC and TPS for $100. New from chevy, they're $216. BBK makes an 80mm TB (stock is 75mm) that list for $399.
Will be running 36lb injectors with either a Haltec or the new Holley DFI / harness.
If your doing a TPI conversion, Street & Performance sells a custom harness for the RamJet that uses the TPI ECM's.
Fuel rails are unavailable from chevy at this time, but list for $327 without the regulator. I bought 3 feet of 1/2 id stock from Lingenfelter for $14 a foot. The shop is charging me $150 bucks to machine the rails, and I will plumb them myself with braided line and an AFPR.
As for HP figures, the RamJet has a runner length of 4.125 inches! That's less than a Victor Junior single plane racing intake.
Compare that to the TPI and SuperRam runner length. The miniram has short runners, also.
The real horsepower - like any motor - is found in the heads. The FastBurns have 210cc runners - easily enough air for my 10.5:1 383. Combine that with the Lingenfelter .525 roller (.560 lift with the 1.6 roller rockers I have), and you're talking close to 500hp. Chevy built a 383, 9.7:1, .540 lift, FastBurn head motor that dynoed at 497hp. I figure my combo will be in that ballpark, but the dyno will tell the whole story.
Should have the rails done next week.
I'll put up some more pics at that time.

Some picks from under the intake, please.
I´m sitting here negotiating with me self about to order or not . . . How´s PCV in that thing ?

Here's a question? Ramjet intake with GM fast burn heads or Mini-ram and AFR heads with maybe 195cc runners. Which would make more power?

Blade

They will probably be very close as power is concerned... but what is MUCH cheaper ? GM's stuff!

I believe the MiniRam with AFRs would make more power than the RamJet/Fastburn combo. But, Blade is correct that the Ramjet/Fastburn combo SHOULD be cheaper (when all the parts are readily available, like the fuel rails).

If you took that savings from the RamJet/Fastburn combo and invested it in further porting, then it could compete or exceed the Miniram/AFR combo. Possibly at a lower overall cost.

I sure HOPE this becomes a viable alternative to the Miniram...just so TPIS will get their prices more in line. I've never have had a problem with TPIS for their quality (I'm sure some do). My big beef has been their outrageous prices.
