At that elevation you should turbo it

What pulley set up is that? Seems like you're spinning that 2.7 really fast.

Last I knew, he was running a 10% lower, 2.86 upper, and hitting 7200 RPM between shifts. So, his male rotor is hitting 37k RPM peaks.

Holy cow that's moving.

Close, +10 lower 2.74 Satera clutched upper, shift at 6800 but engine revs to 72-7300 between shifts. Yea, it’s SCREAMING!!

I did another 60-130 run tonight, 5.77 exactly the same as run a week or so ago in the same spot. Cars being very consistent for a stick car!.

Tonight

last week or so ago, less than a ft of each other in run distance lol

Ended up adding more boost today. The 2.75 was giving me 18.5psi at this elevation. Swapped to a 2.5 and seeing 20psi now. It's hard to make boost at 5200ft. We were expecting a bit more boost but happy where it's at for now.

Going to try to get some dyno time this weekend and post some numbers on the 2.5 pulley. Will likely switch to the 2.35 and see what it does after.

What for Manifold Air Temps (MAT) you seeing on a pull?

In that case, 39.5k peak RPM on your male rotor... must be a wailing banshee.

And so far so good on the rotors 🤞🏻🤞🏻
But heat is an issue, even with maintaining a 21-25F intercooler coolant temp MAT went from 90F to 130 F during the pull. I think it’s going to be the Achilles’ heel of the Kong because from what the video said it makes a lot of heat, more than the IHI. I’ll post a video of the pull log at some point.

Here’s a Kong with a 130 mm TB with a custom E’s garage whipped up CIA.
Will be dynoing next week.

Beautiful. Still too expensive

Nice!!! Do you know which pulley set up?

Dyno Shmyno , slips bro need to see those slips (actual 1/4 mile race slips)
🤣🤣

O E’s a racer, that will come!!

Here’s his car, I think it’s going to take a bit more than a Kong to beat it though.

IW lower 3.00 upper, stock cubes, decent cam, catless down pipes, made 19 psi at 5500 rpm on a short test hit with only 10 degrees of timing, he said it felt good for only 18 psi of boost. It will get some Z dyno tuning then hit the track then put more pulley to it possibly.

Here is that log video. Watch MAT in this video even with 21-25 F intercooler coolant temps MAT goes up quick! From the SDPC testing video they said the Kong makes more heat then the IHI does and they had to use PWR cooling bricks with it to control manifold air temps. If that becomes the case they are going to get hot quick in part throttle mode street driving with a spicy pulley set up on it. If that does become true I think a Whipple 3.0 would be my choice of a next blower because they cool the air even in bypass mode which keeps the rotors and blower case cool. Hopefully they start getting better reliability reports as Unfortunately I’m still hearing from install shops they’re still seeing rotor issues even with the latest 5 support front plate units . Maybe Gen 7!!! Maybe Kong??? Time will tell.

Just messing with you guys ,looks like a nice set-up just came to late for me, the cost/benefits of swapping now aren't worth it to me, but it's definitely an option for those still in the deciding phase.

Will be interesting to see how it translates to real world times on a basically stock car vs the other options out there, and it's longevity.

I’m just going to turbo the freakin thing

I think it’s great. If it was $4k

Nice! Look forward to seeing results. I've been having a hard time getting on a dyno out here. I really want to get numbers on the 2.5 and 20 psi before I swap in the 2.35.

Don’t you mean up here? On mt. Everest?

If had it to do over again exactly this....

Still can’t believe we don’t have numbers on this yet

More than a 2.4/2.7 less than a whipple. Where's a good 4.9 KB when you need one..
