Ditching Dual Quad Eddies for Quick Fuel Race Q-950

[383man]

When INDY "built" my motor, they said the ModMan intake was killing my top end HP..... At the time, keeping the look of dual quads was more important than function..... Now that i have the engine in the car and driven it, i'm after the HP......

I just found out today that the NSS club my brother runs with now says he can run one carb so he is going to try his Indy single plane intake and a Dominator. So I will have something to compare the Mod-Man intake to now. Ron

That will be interesting...... Give us an update when the results are in!

Will do. It should be in about 2 weeks. Ron

From my view the dominator looks wrong. Super Stock Racer and mine are some of the quickest cars in N/SS (not the quickest). They both have acchived 8.9-9.0 on Eddys. This Cuda just went 8.87

I have been logging my Jet/Bleed sizes and A/F info. The QF950 is very tune-able. You will like it much.

Do you have time slips to go with your changes ? Or how are checking your changes ?

I believe with our cubic inch, we are just about or are the quickest. The ones going sub 8.90's are all well over 600+ cubic inches with tunnelrams.
I went 8.96 with 2 carter 750's. 9755S competition series and it had more. I missed the tune up and was way lean.

That thing is insane. I saw the vid of that pass. What does it weigh?

 

[SUPERSTOCKRACER]

I decided to pull the tunnel ram off and put back the indy crossram with the 2 Carter 750 AFB carbs and see how fast I can get it. This is a new build that I tore apart and rechecked all the mistakes the old engine builder screwed up on.

I'm glad I didn't sell these carbs and held on to them.

The real reason my brother is doing it is actually to try and get an idea if the Mod-Man intake is very good. Atleast this gives it something to compare it to and since my brother like running a Dominator it was an easy choice for him. I guess we will see how it works for him. His eng is a 511 and the car weighs about 3550 with him in it. Best with the Mod-Man and dual eddies has been 9.90's @ 136. They changed the rules as you can run a single carb now in the 422 NSS club he races with. It would be cool to compare the Dominator and single plane to the Indy box type crossram and dual Eddies that I believe you guys are running. Ron

Recently built 572 by Best Machine with a dominator for Alan Ross. Dynoed at 948hp. Car weighs 3000lbs w/driver had been in the mid 8.8X's, and I believe mid 155mph. Mine with Eddys has been mid 9.1X's at 147+.Based on ET they're very close. With Holleys on the Indy Crossram I've been 151mph@3350 that shows 923 vs 156@3000 which shows 912. Granted this isn't very scientific But I've raced with Alan at a few venues. At 350 lbs heavier I'm usually .25 behind him. Mines never been on a dyno. Both motors are of similar head, cam, compression. Alans car is a backhalf 4 link, trans brake, and 14x32. Mine is ladder bar, foot brake, 10.5Wx31. So for what its worth I think they're pretty close.

We dynoed my motor at Jim Kidd dyno in Michigan with Holleys an made 921 hp.Jake and Sean did the motor Best I could get was a 5.94 660 time. Switched over to my trustworthy Edelbrocks and car goes 5.80 in the 660 on the same day. That was when I had a best of 9.25@146 mph last year.

You mean 660ft not 330ft. I've gone [email protected] with the Holley's. Eddy's will be back on for next weekend.

You guys definetly have alot more motor them my brother runs and he runs a good bit more eng then me as your cars are flying and I love to watch fast Mopars. I have always heard from many that say the single plane and Dominator will beat most combo's other then a tunnel ram setup. Now thats not me thats just what I hear alot of people say. Cant say I ever saw anyone test the Indy crossram vs a Dominator and good single plane but it would be cool to see someone to that on just one car on the same day. I know a good friend of mine took the Dominator and single plane intake (Victor) off his 499 Cuda and put a tunnel ram with two Holleys on it. I dont remember what size the Holleys were but he could not get it to et and faster as it ran 9.80's on the Dominator and 9.90's on the tunnel ram but the tunnel ram did have more mph. Maybe if he had worked more with the tunnel ram it may have went faster. He only left it on the car about a month. We have never dyno'd either of our engines.
Doug it makes me wonder that if you were running a class that let you run your same combo but could use any intake and carb como you want to try and go your fastest which would you want to use ? I am curious to see how my brothers car runs with the Indy single plane and Dominator as compared to the Mod-Man intake and dual Eddies ? Ron

I wish I could make power with an OE cross ram cause it would be on the car. The Indy cross ram at least looks like a Rat Roster. If it was strictly bracket it would probably be a single carb. But a tunnel ram with Eddy's is intriguing.

IM MODIFYING AN INDY TUNNELRAM for the indy wedge as we speak. Going from dominators to Edelbrocks. It's a little bit of work but seems to work great on my indy hemi.

I tried that too. Lost over .25-.3 over the Indy crossram. It was like a cork. I have a stage III OE Crossram sitting on my shelf. I tried 5 different OE Crossrams and this one made the most power over the Stage I & II. & 3 stage III's.


But i'll tell you it was one smooth running engine with very good throttle response

I love the way my car runs but I would really like to have an OE style intake. However, I can't afford to loose 2.5-3. Do either of you guys know how Allison's CNC ported OE style performs as compared to the 440-25?

I would actually love to run the stock factory crossram just for the wow and cool factor when the hood is lifted. But when I put it together I did not have the cash for the crossram setup and the Indy dual plane and 850 DP really has great driveability manners on the street and works ok at the track.
When it comes to going real fast I always think of the Pro Stock cars from the 70's when the Hemi Mopars ran the home made intakes many of them made that kinda looked like a short version of a tunnel ram. They were trying to go as fast as they could since they were heads up racing and of course they used 2 Dominators on the intakes they made and used.

The Indy crossram is cool but it really dont look like a crossram to most since the carbs are almost straight in line but I understand it makes alot more power then the factory crossram. As you said Doug my brother likes the single carb and single plain for racing if the class allows it since its easier to keep in tune then dual carbs and that way you can spend more time racing and less time tuning at the track. I know my 10 second street car is slow compared to your low 9 second 64 and SS racers race cars but I do love how well the single 850 stays in tune once I got it where I want it. The last two times I went racing and I drove the 45 miles at one of the races once I open the hood and did a visual check to be sure all is ok I never lifted the hood on my car at all the rest of the day both times and in fact thats how it is most of the time I go racing as the car runs fine on the first pass and all day long so I never even lift the hood as it has time to cool down some but even when I did not have alot of cooldown time it still ran right about the same et. I like a low maintnance hotrod. Ron

Allison's A & A crossram has been redesigned but still falls way short of a indy crossram.
I believe IIRC the A&A crossram made 15-20 hp more than the oe crossram.
His original version was no better and actually worse than the oe crossram.
