Hi guys, im currently running a Mini Ram on my car and due to poor craftsmanship and design The intake port line up poorly
and Ive been hearing of uneven air distribution which I believe.

Anyway i was thinking of converting my old victor jr to and dry
manifold ,seems like it would be a great choice in my opinion.
My questions are do you think this would be a good idea and what should i do for a throttle body ? I was thinking of making a
mounting plate to use my standard 58mm upright or can I find a budget minded throttle body that will accept a usable TPS and idle air?
I know this is not exactly prom related but Im asking from guys who have tuned with these kind of setups and would know of the pros/cons and ease.

 

I thought of doing the same thing but with a air-gap intake. You should be able to make an adaptor plate, the main problem is going to be mounting the injectors properly . But the whole project shouldn't be too dificult

 

Edelbrock now makes a victor jr for EFI W/rails its in the new section on their site.Also their is a member that dynoed a single plane EFI vs. Stealth ram and the Stealth dynoed better.Do a search in the TPI section for stealth ram you will find him mike********

 

Well Ive just searched and search but could not seem to find it,
I found lots bout super vs mini vs stealth but nothing including the victor or how they perform.

 

This will work. The Victor Jr is a good manifold choice. The upright TB is not only do-able, I know someone that used it on an Olds engine w/no problems. He later changed to a GM monoblade TB just for the round input area. Made it easier to fit and air cleaner.

For a while he also used a BBC TBI TB w/o the injector pod.

I look at your quest as this: Build whatever is within your ability, purchase what you cannot build. Oct 2002 CarCraft has an dyno test between the HSR and a Holley MPFI, not much difference.

Thx Rob,
I really think I have some to be gained over the Mini Ram.
Waht do you think?

 

i think accel makes a 4hole tb thats 1000cfm. supposedly it has a carberator flange for just such applications. that only leaves the injector rails an ijector bungs. just a sugestion.

also using a tb with a 4bbl carb layout should in thoery keep airhandling in the plenum of the victor the way the designed ie a 2bbl tb might disrupt the intended flow patterns.

 

Well I thought about that but in many stock car classes cars are limited to a 2brl carb and alot of them do so on a square manifold.
I would really rather have the 4brl throttle body but im trying this low budget and I was worried bout the IAC. .

 

ok go buy a big chunk of aluminum got acces to a drill press. grab some holley 750 throttle shafts and get creative.

iac is

20mm by 1.25 pitch just in case you need to know.

and its not terribaly hard to make a tb styled after a 4bbl. if you cross dril the iac passage accrod all four sides into all the opening under the blades then you just need to plug 4 holes. then just mount the iac some place simple. boring the holes for the Throttle bores in something like 6061 is simple materials so soft you could use wood hole cutter for just take your time and pace yourself.

there alot of way to go about this i didnt think teh accel tb was that exspensvie and i thought it had an IAC provision ?

 

Well I just picked this up for $250 ,gonna work on the intake now.

 

So how much does it cost to get the injector bungs welded in along with the fuel rails? I was considering this in the future when I go with a bigger cam but I'd really like to know where to get all the parts.

 

From where?!?! I thought those went for near $700! I want one

 

Well I think the ones with a IAC are 700 but the ones without
I saw for $578,I had no idea how much they cost and i searched forever to find one to see if that was a deal.
I found it on ebay buy it now for $290 with 2 mins. left,I bid 280
and reserve not met yet and ended ,so i mailed the guy and told him $250 and he said $270 and I bought it.
I messed up above I said $250.

 

I have a Full Throttle Performance 1130 Street Fighter TB ..and mine came w/ a IAC and TPS and paid 565.00 for mine. They even made me a custom kickdown lever for the automatic as well...

For IAC, you can do what i did. I got one of the IACs off a Buick V6 where it bolts on the side of the throttle body. I then made a steel plate that accepted two hose barbs, and screwed that plate to the IAC with a cork gasket between. I then hooked it into the vacuum line from the PCV hose. It worked pretty well. The only thing I didn't figure out was where to get clean air for it.

Then I went and bought a TBI with an integrated IAC. If you want the IAC described above, you can have it for the cost of shipping.

 

Thanks alot for the info,
That is really cool of you for the IAC but i planned on just doing the same to my stock if possible.
What are you guys using for intakes?

 

I vote for keeping the IAC a part of the cars history, not it's future! IACs are a PITA and if you've got the car tuned well enough and don't drive in cold weather, there is very little reason to keep it.
Anybody know where I can find a single plane vortec intake manifold ready for the injectors and TB?

just saw this, hope it helps

Well unfortunately I have to drive the car in cold weather because I live in cold @ss Pennsylvania.
The weather has just risen above 12 for the first time in a week.

 

Im using a Vic Jr. Single Plane...

 

From what I've seen most of the air distribution problems are from too small of plenum, or the rear wall of the plenum forming the wall of the last runner (s). Sometimes a little fab work can go a long way.

As far as using a wet manifold in a dry application, you want to size the manifold a little smaller then what the book says. As a wet manifold a serious amount of air is displaced by fuel, so when you go dry you wind up with too much runner volume. Then you start having to add alot of AE to cover things, and start losing responsivness.

I'd look at like a Weiand 7525.

 

Wow SKWEEZN that looks really expensive,But very cool.
What kinf of valve covers are those,they clear roller rockers?


Well with the victor I have nothing to lose ,I own one and its on my blown camaro that I soon plan to convert over to a EFI and I will be using that setup on it.
So if its does no perform any better than it will go on the maro.

 

Sweet! Looks like what I'm getting ready to do with a Weiand/Holley Team G 7530. Still debating on whether to go with a 4-bbl TB or a 'stock' TPI 58mm unit on a 90-snorkel. I'll use the stock rails though...

 

Heres a good site for picks of converted manifolds http://www.hotrodsolutions.net/IntakesEFI.html

 

That's what I was looking for. Thanks!

 

How hi you gonna twist it?. Running a 7530, DRY, is gonna raise it's power band signifigantly. Unless you go back to TBI or patch the code your have a 6375 rpm cutoff.
Making all the air make an extra 90d turn wastes alot of energy.

 

It's a 383, with 234/242 .560/.570 solid roller. Heads flow 275 on the intake.

I'm planning to start it off with a 165 MAF system, with the needed modifications to handle the increased air flow (Z06 MAF translator, modified tables, bias adjustments, etc). Being a stroked motor, I probably won't want to go too high, maybe 6500.

Once I have my fun with the 165, I'll try the 730 code & see what happens.

As far as the 90, I have similar concern. I was thinking maybe more of a box-type plenum to bring the air in at the front or side, and then give it a place to relax before it hooks down into the intake runners.

We'll see what the hogged-out TPI intake stuff does, and where it chokes. Maybe something 'smaller' than a 7530 will work better.

Anyone seen a TB that has an 8-injector array right under the butterflies at a 45 angle? I saw one the other day, looked pretty sweet, don't know how effective it would be in directing the fuel though.

 

Here's one with four injectors not eight

 

Ok ,
Just got the intake off my camaro and am about to start
Drilling for the injectors.
My question is how important is injector positioning?
Am I gonna lose power because the injectors cannot be angled enough? Is it nothing to be worried about?

 

I was going to try and use the existing TPI rails at the stock angle so that it drops the spray at the back of the valve. I think it can be done with some 1/4" plate cross-drilled and routed for the flange and rails. Just a single plate should work.

 

here's mine:

^^if that doesn't work than this will:

Up and running, seems like it'll be a lot of fun. Off-idle response is pretty jumpy, guess I'll have to do some tuning work for sure. Must be that intake volume with MAF/383. Yes, it clears the stock hood.

 

Craig, where did you get that cold air tube, thats exactly what i've been looking for.

 

Summit Part # SUM-237100 costs $109. Frustrating, paying for a piece of plastic, but I looked all around for alternatives. Almost converted a newer-model Dodge Dakota throttle body hat, that would have probably worked too. Comes as a kit with K&N filter for more $. Do a Summit search for "Summit Cold Air".

Had to shave it to drop it about 1" for clearance, but it works.

 

craig you got the maf translator working ??

 

No, but I will. Been busy with other stuff ;^)

 

Craig, What is the performance difference ?
What does it feel like compared? How has the power curved changed?
What did you convert from?

 

It's unreal...
Coming up from a stock 305TPI. Seems a wee bit short on torque down low, but it just keeps winding up well beyond my comfort zone...

 

Craig, whats up! I'm glad to see that your car is running. What do you figure it will do in the 1/4?

Remeber chip 26? Well, I figured out that the car was NEVER going into closed loop. When I finally wired up the 3-wire heated o2, CHIP 26 glowed all the headers red in a hurry!

Chip 25, 24, and 23 all did the same thing (RED headers)!

I ended up modifying the hell out of the Ed Wright .bin but using a 24lb constant and right now the BLM's are arround 122 - 130 (not too shabby, I think). But, I used Chip 26's open loop programming.

So the whole damn time it was running that good in OPEN loop! You really need to go for a ride in it now!

Laura and I just wanted to say hello to you, your wife and the in-laws. We hope everyone's doing well!

Craig, ya there?

 

Nope, over here....

Good to hear things are moving along for you. All's fun on this end.

By the way, for anyone that's planning on doing a single-plane conversion: Prepare to do some tuning. It's getting there, and I haven't spent the time I should yet, but there's some work to it especially on throttle transients...
