The Ram Jet Intake is already available for Vortec and Fast Burn Heads from GM.

http://www.gmpartsdirect.com/results.cfm

Seems if people were truly interested in an intake of this type, they'd be using this already.

 

The ram Jet would cost twice the amount of a Stealth Ram by the time you bought the intake, new throttle body and did what you is needed to relocate your throttle, throttle pressure and cruise cables to the other side of the intake. DF....... :hail:

 

Definitely interested. I've been thinking of building a clone of the sdpc 360HP TPI motor which is basically a 350 with vortec heads machined for the higher lift of the lt4 hot cam. I think the stealth ram coupled with the vortecs and hot cam would be a screamer up to.

Comments please...

Oh, like many others on here they'll need to trim the height down a bit as it will not clear my ta's hood!

 

Our choices are few:

HSR with an EO
Superram (after skipping a house payment)
Building a "test only engine" and doing the swaporama every two years.

Funny how the visual test makes matters worse for everyone. Well-tuned cars with non-certified parts pass all the time on the rollers in well-run states...

Peace,

So, have there been any protoypes built and tested that you could give us some hp and tq numbers from?

 

I too am interested in one of these intakes. I am now holding up my motor rebuild for the well anticipated intake. Has anyone played with dyno 2000 on the combo and seen any kind of numbers for different combos. When I get home I am going to try some out. I am thinking the basic being stealth/vortec 284 hr comp cam, 383 with 10.5 compression.

 

Well, I'm tired of waiting, after talking to Ominous_87 I'm getting a Superram. I will still have my bottom end torque and will gain a lot of HP.

 

Just purchased my E-tec 200's anciously waiting.

 

Paging Doug Flynn oh Holley???????????

Any update on this as of yet? shorter plenum? anything? nothing on holley's website about it, least that I can find?

later

Intake availability in Kali is driving how I build this car up. I already cleared building a new bullet for the Formy with "The Boss". All I need is the nudge regarding the intake, since that will drive the combo...

K

 

I would not mind product testing.

 

Holley won't have the *****, or money (that they would want to spend) to make it CARB legal for us Ca. residents.

Get you SuperRam and get on down the road....or you'll be an old man(er.....lady?) before it happens.

It cost $$ to get CARB certification.

 

lol

I had considered doing the intake swap every other year, but probably will have other things in the way. Truly a shame.

If memory serves a manufacturer has to pony up around $50K to test a part with the CARB. That will probably leave me with the Superram, but at $1300 new it's a pretty penny. I could not care less about the usual difficulties mentioned with the Superram (its size, multiple gaskets, working on the valvetrain, etc.) so if one comes up on E-screw I could always bid on it...

K

 

Should be available the end of this year.

Options for a CARB EO are being looked at, but at this time there is no plan.

 

Can I put an order in now so I do not get got on the inevitable waiting list, that will form when all of us with heavy breathing 383's order one of these fuel injected life savers. I have check card in hand.

 

Thanks for the update man. I don't blame Holley for not wanting to "kiss the ring" at the CARB. If things change...well, I might live in another state before things change here. heh

Peace,

K

 

Any updates on this?

Doug Flynn where are you?

Nothing on Holley's webpage as of yet?

Lowering the base heighth?

Anyone?

dam it ... quit posting to this thread !! I'm tired of getting STROKED OUT !!! There NEVER will be a Aluminum MPFI Vortec intake !!! These companies have thier heads up their rears !! they instist that no truck owner will ever fit up thier truck , come to GEORGIA MORONS !!! !!

TVP

 

I would have bought one. Bought better heads rather than pay for a SR and SDPC base.

As far as changing intakes in Cali. Vortecs are extremely easy to change. The gaskets are reuseable. I've had mine off numerous times. Takes longer to get the coolant out than to unbolt the intake. (unless your one of those pull the bottom hose guys)
Hopefully, Holley will make the current one fit a 1206 gasket too.
Had to get mine welded to fit my Brodix heads. Only 200cc too

 

I would not only be interested in this but I would buy it the minute I saw that it was out if it is offered at or near the price of the current HSR. Modified vortecs can flow easily up to 6K rpm, and make up for the "lack of torque" the HSR is fabled to have. Pair that intake with a set of Fast burns or even E-Tecs and it would be an impressive combo.

Any updates D F?

 

Count me in too!! Nothing else that is out there appeals to me, I was about ready to settle and order a base from SDPC until I found this thread. I don't care if it's emission legal, but hood clearance for a firebird would be a good thing.

 

Well, my choice is made. Found a superram plenum and runners for $600 and decided to skip half a house payment.

 

You got a SDPC base yet?

Or you not gonna run Vortecs with the SR?

If you decide to go Vortec SR be sure to read my comments on getting it all to fit.

 

Yea, I've got the sdpc piece and am going to run vortecs. I've also read your comments about the steps you had to take. I'll be reviewing them again soon. I need to mock everything up so that I can weld my egr provision into my passenger side header and have it be the right height. Then I can send the headers off to be coated.

I have one question for you though... would you go to the expense of having the whole setup (plenum, runners, and intake) extrude honed?

I get to sell these slp siamesed runners now...

 

Depends largely on your skill and ability to invest imte into porting your combo.

I am a friggin nut when it comes to shaping the intake tract, I would never hang an intake part on a motor without first giving it pleanty of love.

I spent alot of time hand porting my base. The SR plenum and runners required far less work and already flows like SOB out of the box.

Flow numbers that I have seen show the SR runners flowing 280cfm box stock. HOWEVER, port matching and getting everything to line up at the plenum box is CRITICAL, and can be easily accomplished by hand. Then matching the runner ports to the gaskets that mount to the base is also a good next step. and of course blending shaping and polishing the rest of the runners.

The SDPC base needed lots of work IMO. The bosses need to be trimmed down. The round runner ports need to be opened up and gasket matched. and then blending and hogging in the middle. the gasket i used between the intake and heads was a Felpro 1255. however do not exatly port the SDPC intake runners to this gasket. the intkae ports on the base are sloppily cast and you will kinda need to deal with them on a case by case basis.

So i dont know, its up to you, extrude hone sounds like a sweet option for the base, i spent tons of hours on my base, i cant even recal hopw many really, but alot, 20 or more.

but in the end it all worked out real good, i got the SR and little 170cc heads on my 385 and she runs real good

 

how about a group buy for us ? then wecould give ya feed back on it ,just a thought

 

I've been thinking about taking my '91 back to EFI when I rebuild the 350 (as a 383 .) A Vortec HSR would pretty much settle it for me.

I'd buy it.

 

Any chance it will be unvailed at "a certain show" this year :hail:

 

id be in for 2

 

Only four months till years end, I wonder if were still going to see one about that time?

 

ttt, I've got another short block that is ready for vortec heads and a stealth ram. Should I go ahead and buy the heads?

 

as they say in sales ....

call back and ask for mister blue , I'll be the guy holding my
breath waiting for you !!!

if they had them .. I'd be on my 4th or 5th one by now !!!

TVP

 

Ya, I hear you. I just want to buy the heads so I can get everything assembled/painted.

 

Any word on it being available any time soon?

 

considering that just the TPI lower sold by SDPC2000.com and cast by edelbrock for GM is only a bit less than the bare upper and lower for stealthram I would say a resounding yes. Besides even if you put SLP siamesed TPI runners and a ported TPI upper with a good throttle body or even a complete accel superram upper with larger throttle body you still wouldnt reach the capacity for airflow available through the Stealthram archetecture.

so "D F" if you "know somebody" tell them not just "yes" but "HELL YES"!

I already own one, and I would buy another and ebay off all my accel crap in an instant!

PS tell them "HELL YEAH!" on the vortec bases for the 144 and 172 blowers as well.

PS #2 how about some lowers that fit larger port small block heads with 1206/1207 gaskets some of us have had to weld and port to make them fit the 200+cc intake port heads available everywhere. You know what a bitch that is?

 

T minus 3 months and counting... vortec stealthram approaching sales.

 

oh really? wheres that come from?

 

A little ways back in this thread, DF says "should be available by the end of the year."

 

How about we all start emailing holley to ask them to build it. Maybe, then they will realize the interest and actually make it or at least give us a final answer on it. Yes, or No.

 

Looks like it's for sure (so far)....
http://www.chevytalk.org/threads/sho...rue#Post948824

 

I'll second that...It would be cool to be able to use an AFR 220 head or similar with the HSR with no mods to it at all. That would be perfect for a 400+ CID small block.

 

Hmm, first of the year now. Oh well, for vortec heads and no ltr crap it'll be worth the wait.

 

:hail:

Sweet I was goin to just sell my heads cause I hated the SDPC base and it robbed me of valuible HP. I'm sittin at 243 rwhp on an otherwise built motor. if not for the dang ltr set-up I would see 350+ rwhp easily. I'll start savin seens how its goin to be out the first of the year...

is there a place where we can reserve a intake so we dont have to deal with back order I wont one now!!

 

Whats wrong with the sdpc base?

 

Now I can run a Vortec heads and later on, upgrade to fastburns.

*Evil Laugh*

 

I would buy one that fit 200cc+ heads..... maybe next year :hail:

 

I'm starting to get anxious..... Every time I get in the t/a I walk by an assembled 350 short block on the stand, then get in the car and fire up the 156,xxx mile old 305.

 

Hopefully it will be SMOG LEGAL. I live in CALIFORNIA!!!!! I beleive the current one lacks the provision for EGR right?

 

I had so many problems installing this piece. alot of material had to be ground away so my distrib. could slid down into place. then more material had to be ground away so my alt. brackect could fit snoggly. The when it comes to HP this intake robs horsepower, maily dude to the LTR design, so flow is still horrible. And have fun puttin the runners in if u already torqued down ur intake. Bolt gets in the way so bad that the intake bolt had to be pulled back out and the intake retorqued.

I see with the HSR a deffinate increase of at least 45-50 HP alone. that will eaily put me into the 300HP with a reburnt chip!

IMO SDPC vortec base is a waste of friggin money more headaches then gains out the POS and soon the HSR should be just a few hundred dollars more and be 10x more worth then the SDPC base.

I wonder how it would react to a super ram upper?
