CSK this is a cool project! Thanks for sharing. Keep on truckin'
Thank you HardcoreB, & everyone else also.
Made me some 12in ram tubes for my Hilborn EFI, bought some bulk 2 1/2 inch stainless steel thin wall pipe, save myself about 300 bucks, these longer runners should get the car to leave harder & HOPEFULLY get a better 60 foot ,. I even made the bell end, using a bearing press & one of my old drum brake hubs, had the perfect taper to make the bell.

Got the air cleaners on they slip down about halfway to where the runner goes about halfway through the air filter, it'll work great for the street, when I do go back to the dragstrip, all I have to do is just take off the little aluminum top off of each filter and will be wide open

great tip on making the bell end ! that's one reason i have so many small chunks of "stuff" scattered around. you never know when something needs a fabbing "shape". you may only use it once, but when you do, and it's successful, [as in your bell end fabrication] then it has been worthwhile hoarding that item for it's "intended" purpose.
Having the filter in place may actually help with keeping the siphoning affect minimized compared to them being open on the top.
Worth a test imo.
Nice job on the stacks.
I’ll be interested to hear if there’s any seat of the pants difference from behind the wheel.
Thanks guys, I should see some LB/HR of fuel changes in the tuning of the main fuel table, my car wont hook on the street to see if the converter launch [flash] changes, will have to see that at the track in my data log & the time slip, will take the car out today & see how it drives on the street. Dwayne I agree on the filters, I can remove just the alum tops & the filter stays on the ram tube & would block the siphoning, like you said it is all worth testing at the track.will keep Y'all posted.

Went out for a short drive, had to wait for the cop to turn left & I went to the right on the highway 529, nailed it in 2nd gear up to 6100rpm seems to pull about the same, track time will be the tell, drivabilty is much better with the longer runner, the ECU did add about 11% more fuel in the WOT fuel cells 5000 rpm to 6100 rpm The length of the intake runner was 17" went to 24" to help lower RPM for a better 60' time at the track

I think I would try leaning it down at light part throttle cruise under 2500 RPM to 14.8 AFR or even leaner 12.4 to 13.2 it great for best power at WOT or more pedal pressures but less fuel AFR at light throttle high manifold pressure seems to be better to me

I have tried it leaner but it does not like it, makes it run a little warm, not bad but it is a good 10 degrees more , gas millage has been 14mpg on the road. I do appreciate the input Cab in the video it was running high 13'S low 14

Doing a Track rental this Saturday night @ Houston Raceway Park , the DA looks like it will be 1700ft from the forecast, I am bringing some different runner lengths to try out, the ones I made the 11.04 @ 123mph made for a total of 17", the ones on the car now make 24" & I have some for 19" , I will run these with the lids OFF the air filters ,I hope to make some tuning progress.
Quote,, I absolutely love this car. Thanks Mark M

I would like o see you hit it from a in gear idle at the track to see if flashing the converter will help it 60 Ft. better Some cars like that and some don't
