Wilson manifolds?

 

Is that pic just the Victor within the entire kit? I did not look at kits on their site just EFI manifolds. will do now. VIC Jr EFI manifold is available in a big block application.

 

This car is scary.. Even with my brand new 275/40/17 tires I get no traction when I go wot.

This is 2nd gear part throttle to a WOT mash. Car kicked out to the left so I grabbed 3rd, kicked back to the right so I let off and grabbed 4th.

If my math is right, that is .4 seconds between shifts.. I guess I'm getting old and slow

nice, how much power you think your making?

 

Not sure. Won't really know unless I dyno it, or get some passes in at the 1/4.
My DC is absurd and 02 starts to fall at upper RPM so I think I'm losing a little fuel pressure up top under boost. I have not changed the fuel pump yet so I can only guess it's stock. 30# injectors, boost, etc.

So anyhow, desktop dyno thinks it's 500hp. I was also playing with datamaster having it calculate my WOT run and it thinks it's 489hp.. (images attached)

What do you think based on the combo? The dd image has the combo data.

-- Joe

 

I think it's safe to say that everyone is eagerly waiting for this Joe....

 

i'm not sure how the DD forced induction part works, i dont know any specs on any blowers

But i'd normally guess that combo to make 330-340whp n/a or so, plus 6 lbs of boost thats 25-30% more power i'd think. Thats gonna put you around the 400+ whp mark which is somewhere near 500 on motor, if not abit more.

either way it should run very very good

 

You should be making close to 430hp or slightly more to the wheels. If I where you I'd stay out of the gas until you fix that fuel issue with the injectors and pump. That DC is crazy high, I'm sure you already know that.

 

I'd like to but I need to change the fuel pump, and I need to fix the oil leak. Been really busy with the house lately so things may have to wait until the spring.

-- Joe

 

I agree with Orr89, I would bet you're pushing 430+ rwhp. Get it on the dyno and find out!!

Got some news on mine. I got it started this weekend and tuned the idle. I'm using Accel's DFI thruster. The tune is pretty rich all over so I have some work to do, but I got it started and checked over. However, it doesn't turn off? I think the ignition switch might be bad (see post in electronics). It was kinda funny, I was done for the day so I turned the key off and took it out, but the engine was still running! I laughed and pulled the ignition harness to turn it off. Haha never had that happen before.

I'll try to get some pics up this week.

 

Here is a picture of a Accel ProRam that I'm building with a modified Edelbrock elbow and LS2 fly by wire throttle body. The Vortec distributor (without cap) is simply used to spin the oil pump and provide a cam sensor signal for the LS1 ECM.

 

Nice setup!

Joe, sorry for the delay in my posting. Theres no way the Pro Ram intake could be taken down to a shade over 4 inches. Its comes at 5.75, and the way the fuel rails are designed to mount would pose a problem.

On a side note, would it be wise to gasket match this intake to match my 1206 intake ports on the heads?





Even though I've cleaned up a few heads and intake manifolds, I'm by no means a "natural" when it comes to this kind of thing. What worries me more than anything is how much material would need to be removed from the top of the port where the injectors come in. Any suggestions?

 

Same thing with the holley, you'll never use a 4bbl throttle body as the linkage would crash into the rail, but since I used an elbow I was able to cut it down to almost nothing.

At least the top where most of the airflow is. From about the centerpoint to the roof should match. The bottom part/floor doesn't really flow anything. We've put steel shims over the bottom of the port and it did nothing on the flowbench, but missalign the top and holy cow!

Be careful around the injector opening. Don't break through the casting like Mike Davis did on his Holley. I imagine it's thin up there.

-- Joe

 

Finally got around to getting some pictures. I'm still trying to figure out the new camera so they didn't turn out too great.

The wiring needs to be a little more organized, but all in all its pretty much done for now. Fuel lines are sort temporary until I get the procharger and re-route them as necessary. As said before, it all fits under the stock hood, which I am extremely pleased with. I'm hoping to get some road tests this weekend. The ignition switch was the culprit, so that's settled, however now my gas gauge is all goofed up. There are 3 "boxes" to run it, ignition, O2, and DFI comp. I plan on mounting them behind the passenger side dash to get them off the floor...

 

Joe et. all, I fell onto this one while posting in another thread:

https://www.thirdgen.org/forums/powe...=1#post3942131

Check out near some of the last posts. That single plane setup looks like slick shlt!!! Figured I'd share.

 

Aaron's vette is in the 9s.

He's new on here, but a senior member over at Corvetteforum.

Thanks for the link. Broken cranks suck! Hope I never have that happen.
A buddy of mine broke the snout off the crank on his maverick and if I recall something almost came through the hood.

This was a very interesting read guys...Great Thread Award!

Any new input guys?

I'm hitting the Pro-Ram/Gen VII swap pretty hard right now, I'll be sure to get some pictures up. I think the trickiest part is configuring all the electronics. I keep my ignition box and coil inside the car, so I have the DFI ECM, ignition box, coil, and Accel wideband to stuff under the dash. I believe that tonight I finally figured out exactly how I'm gonna mount it all.

 

Sorry to but in on the end of a post, but I just pulled my project from the cob webs and have been slowly making progress on it. Here is the intake I have been toying with. Not sure if I am going forced induction yet or not. I am using a carb hat for clearance. Hopefully i can get some installed pice tomorrow.

 

Any new input guys?

I pretty much have the electronics sorted out, and I have been online with the ECM so all that is functioning properly so far. Just waiting on fuel parts so I can plumb it all up.

 

Mine runs good, though I might have the car sold this weekend. Kid wants it pretty bad.

I'm looking at a '67 firebird project. Either that or maybe a '69 corvette.

I know; Holy Back From The Dead. This forum doesnt get a lot of play, it was on the first page. I have the answer you were seeking so long ago. May be too late for you, but perhaps not others. Wilson Manifolds (WilsonManifolds.com) is your best bet; Either modifying your current singleplane with injector bungs drilled at the right angle, and custom fuel rails, to a sweet sheetmetal set up.

My old boss had one of their nitrous set ups. I can definitely vouch for their skill and attention to detail

Yeah but that name to me just screams expensive. I ended up buying a victor EFI setup and doing a custom elbow from intakeelbows.com

 

the best bang for buck I have seen is professional products unit(single plane). the labor to convert would seem to be pricey. I once thought of doing a weiand accellerator(low profile) but again the cost. not every machine shop has the knowledge to do it right.

 

That came up when I was doing mine, but cost was higher than holley, and the height was outrageous.

My frist intake, a holley carb singleplane modified at home worked fine. No welding, injector bungs were pressed in. The fuel rail mounts were awfully ghetto, I admit, but for the season I ran the thing the firebird was it's fastest.

-- Joe

 

This is what I am planning. However, I changed plans and am refreshening the current 355 rather than building a 383 and plan on either porting the HSR, or using the professional products single plane with either a LS type throttle body or my current 58mm tb.
I just wish the adapter for the twin 58 was a little less expensive...
I hope the super hurricane isn't too much for my 355??

 

my custom elbow should be here friday for my victor EFI and LS1 tb. I hope this setup works out well

 

Orr...youre my hero. Good luck with that. Considering your previous experiences, I can only imagine what a beast you'll have at your right foots disposal. I keep looking at my forlorn 305tpi with scorn but its so damn dependable I cant justify ripping its wee little heart out just yet.

I wish I was educated about this topic enough to have a conversation with Wilson manifolds, just to get a set of numbers. We're assuming its prohibitively expensive for our group; but it might NOT be. I imagine theres a point of diminishing returns as far as 'bang for the buck' But I cant help wonder where they are.

Anyone with some knowledge want to send them an email and ask?

 

Got my elbow a while ago and realized its abit higher than i needed, but i gave him the specs and its built to my specs. It will clear under the 4" cowl but my concern now is throttle cable. Stock one wont work so i'll need a longer one but not sure what i'll need. Lokar makes a few longer ones so i may just get one of those and make a bracket for it

 

1998 Vortech truck, 5.7l.

Cable is like a foot longer, fits on firewall, pedal, etc.

-- Joe

 

sweet, now i just need to track that down. Local autopart stores have that?

 

Perhaps. I took mine out of a junkyard truck.

If I recall, even the 4.3 S10 cable is a little longer than the fbody cable.

-- Joe

 

Be careful. My stock cable was too long for my intake/TB so I looped it in a 8 inch dia circle. Was fine for 3 seasons. then first day out of barn throttle stuck WOT in first gear. no damage. inspected it and all was OK? Must have had some issues sitting for 6 months. I would go LOKAR.

 

I'll make sure not to loop mine If i do get a cable thats too long
