Run a recirc valve back into the intake so you can keep the pre turbo fuel injectors and when it vents it sprays the air fuel mix into the inlet of the turbo under the air filter
I believe the extra injectors was a feature Indy cars had to burn off excess fuel late in the race to be as light as possible.
You could get an high-pressure scuba tank or fire fighter air tank. And there are down regulators for anything under the tank puts out. 3000psi to 50 psi.
watching Robs brain work hurts mine but i feel like im getting smarter so thanks <3
The amount of people with knowledge of this vehicle and systems providing information to Rob through the comments is a really cool thing to see that needs more notoriety on the channel
I don’t know exactly but I feel like it can be an adjustment for a clutch kind of like a motorcycle.. idk but love the content bois been watching for years and never disappointed🤌🏽💯
If you need help with the seat, HMU. I've been making IndyCar seats for more than 15 years.
Super cool stuff! Definitely an interesting alternator set-up!
If you pipe the blow off valve back into the exhaust after the turbo could perhaps have one. A glowplug at the exhaust tip would make it all flashy.
Ya gotta have HAL !!
Are you putting a rotor engine in the Indy car?? 😆 That would be awesome, especially a 4rotor!
Pi Toolbox was a data analysis software that Cosworth used, kind of like most aftermarket ECU interfaces for playing back datalogs nowdays. I used to use it on a cosworth developed small UAV motor. Cool to be reminded about that old tech!
Also you should have called up Larry Kosilla for the cleanup, I'm sure he'd have loved digging through it cleaning off the years of dirt.
I think this is the most hyped build ever
Hello Rob, really nice project you got there. I was a racecar mechanic in lower category about 15 years ago. First, the black tube in the lower panel behind the seat seems to be the fire suppresion system. Second, the lever beside the shifter seems to be the adjustment for the rear anti-roll bar that's located over the transmission. Hope it helps.
Cheers!
Martin
Rob be like "Just Finish building a four rotor rx7 that took years to build, I'ma build a indycar"
Still think you should scavenge that chassis to build a thiiic mid-engine hot hatch with that screamin' Cosworth.
I think that handle on the shifter could be a neutral lockout. Pull it then it should allow you to go in to neutral. Could be wrong lol. If you want the air jacks to work, think you’ll need compressed nitrogen. I’ve also seen on the newer race cars in IMSA when the car is raised they disconnect the line and the car stays up. It’s like there’s a check valve. When they’re done they pull the release tether and it drops.
The red lever on the gear lever , don't know for sure if it's this but I was reading up during this week and discovered the exhaust blown diffusers used in formula 1 back in early 2000's had a blow through function for the engine set to essentially go flat out and have the diffuser constantly have air blown by exhaust on the diffuser to create downforce on full throttle parred with cylinder cut making a air pump for the diffuser on "off" throttle scenerios , they would have some lever or flip switch type activation in the cab at beginning stages to go full throttle but not full torque during corners but the FIA found it the devils work
This is an absurd amount of work. Immense respect to you for doing it!
So… not only did he steal most of the Hoonicorn but he even steals the clothes of their backs… I mean… respect
You're talking about not running a bov but even if you don't, the same fuel and air mix will be pushed out the front of the turbo when it surges. I'd assume less than just an open bov. I'm sure there's some kind of programming for the pti that says less-no fuel on any negative throttle map. I could be completely wrong though.
You can absolutely put fuel in before the Turbo, you have to put the fuel in very close to the Turbo and after your blow off valve.
"Theres nothing in this motor that i have ever used… how are we gonna take this to the next step" i thought rob was gonna say chuck another rotary engine in the car
those are aviation/industrial sensors, check Honeywell aviation
This should be really fun to watch come together. I’m here for it
Rob people in the comments are reaching out wanting to help you out on the Indy car project
run the airjacks of s scuba tank with a regulator.
How closely guarded are Indycar secrets? Are engineers swearing because you are unveiling their secrets? I have turned wrenches most of my life, yet the tech in these motors is foreign to me.
Man you're awesome! So glad i found your channel, thanks for all the great content.
I drew the PCI fuel rail and also calibrated all the fuel injectors for the motors.
You most certainly can buy those connectors still. They’re called cannon connectors.
Would a recirculation valve work for these engines
I GUARANTEE THAT HAD A COSSIE V 12 AT SOME POINT. AND YOULL DESTROY IT IF YOU DONT PRIOR TO ATTEMPTING TO START PRE-HEAT THE OIL AND THE COOLANT. THE TOLERANCES INSIDE THERE A SO TIGHT IT WONT CRANK. BUT IT WILL DESTROY EVERY BEARING INSIDE OF IT. PLEASE DONT BE THAT GUY AGAIN ROB
The knock sensor thing made me lol. You don't need that kind of negativity in your data logs lol.
Just run the blow off into the exhaust pre or post turbine……..mechanical anti lag 🤔🤫
I used to work on Indy cars. Call me for thoughts.
Is the lever on the shifter may be a fuel cut for a rudimentary no lift shift system
