FE Intake Adapter

[cjshaker]

Nice work. It'll be interesting to see how the combo responds.

One question, what are the small brass pins used for? I'm guessing they're used as locators to precisely line up the intake to the adapter so that there is no offset on the ports. Is that correct?

Nice pictures, thanks for the post and progress info, keep them coming! I have a few questions, are those flow numbers the manifold only or manifold with the adapter attached? Did you by chance do both?

Also isn't the 4500 Victor capable of close to 500 CFM with mods as well? I'm really curious which would run quicker at the strip, any plans for a back to back comparison or at least under like weather/track conditions?

The flow numbers are for the manifold and adapter together.  I'm told the 4500 Victor will get close to 500 cfm, so there probably isn't a large difference between the two setups.  I only own the 2863/FEpower adapter; the Victor manifold belongs to somebody else, so no back-to-back testing is possible.  Will be a great relief to get the manifold back onto my 496 and see how it likes it.  Last year could only muster a 10.40@128 at Byron using an old 1050 on gas.  Hope it will pick up some from that.

The brass pins are welding rod that I cut for staking the intake/gasket/spacer so that I can get the placement to repeat and stay in one location.  David had left two studs in the spacer for shipping, and the old gaskets that he had used were there.  I had the Fel Pro 1253-3 gaskets for my spacer/project, and I used a new pair to get the desired shape and size so that I could make it look professional.  He can remove the pins after installing the studs and torqueing the intake in place for use.  Joe-JDC

Thanks to all who took the time to answer my questions. I appreciate it. It would be nice to see a few more updates like this.

Was able to make a couple passes to try out the ported intake adapter and yates top.  Picked up some, plus it just sounded better!

Sounds great David! I would have been there, but it was raining around me so I figured the track would have been washed out too. Who'd a thunk. Maybe next time.....

Nice David
You always give me something to shoot for.

Awesome!  Sounds fantastic...

Jay, I realize this was some time back, and you may not remember, but I would like to ask you something about this.
When you tested the torker against the RPM, what was the brake fuel specific doing in the range indicated? Were the torker BSFC numbers lower than the RPM, then climbing as they got closer to the spike at the end of the range indicated?

[jayb]

I don't remember what the BSFC numbers were doing in that range, but I may have saved the data.  I will take a look at my archived dyno data when I get a chance and respond back here...

Thanks Jay.

Intake adapter (MR to C302 Yates/Glidden intake) seems to be working well.  Posted a new best time of 10.01 @ 132mph at the Meltdown drags, carrying an extra 40 lbs in vintage wheels.  Carb is an old 1050 that I picked up from a racing buddy (was on his 496BBC)  Replacement C4 seems to be working flawlessly now.

Balance of engine:

Genesis block 4.31 bore
Scat 4.25 cast crank
MGP 6.7 aluminum rods
CP pistons
Pat Burke prepped Ed heads 2.25Ti/1.75 valves
T&D race rockers
Old Lunati super stock CJ roller cam
Isky redzone lifters
Innovators West balancer/crank trigger

10.01!  Almost time for a full cage...

[cjshaker]

Very nice! With an extra 40 lbs it kinda throws the conventional wisdom out the window. Are you going to limit the car to 10's to avoid a full cage?
I'm surprised you use aluminum rods. A couple questions, how high do you zing the motor, how long have you ran them and how often do you check them? Obviously that adapter is working!

Would really like to have at least one nine second timeslip, but otherwise don't really want to go to the next level on jacket, cage, certification...by running consistent nines.  Makes me wonder what 40lbs less rotating unsprung weight would have done for that pass.  One funny thing at the Meltdowns was that two inspectors looked at my Simpson harness to check the date (they rarely check normally at Byron).  Both people said my belts were good to go.  They are actually four years old now, so I'm glad they saw whatever they did!

Pat Burke built the engine around 2002, and it hasn't been apart yet.  I'm only up to 34 passes on the engine, so it doesn't have much actual run time on it.  I shift at 6700, through the lights around 7000.  Mike from MGP told me that the rods should last a very long time with a 7000 max rpm and the very light CP pistons that I'm using.  I went with the aluminum rods to keep the bobweight to a minimum so there would be less stress on the cast crank.  The low cost forged cranks weren't available at the time the engine was being built.
