Looks to be running pretty rich , and in answer to the earlier question, run a decent duct up from the side of the Rad and drill holes all reound the Filter body helped a lot as did inverting the lid, this however depends on whether it was one of the big sumbitch oil bath aircleaner's .

Yeah it's running pretty rich it's spitting fuel out the exhaust, I'm getting the reg tonight and playing with the fuel pressure, I've been told to run about 2-2.5 psi, apparently dellortos don't like a lot of fuel pressure.

3-5 PSI was normal for the average red motor mechanical pump, Fuel pressure shouldn't be an issue as the float in the Carb should be regulating properly, I'd look at the possibility that the float needed seats are not sealing 100 % as this can manifest it'self in a number of ways or there might be interference in the Choke bypass circuit that is loading her up with fuel at idle.

The audio above sounded pretty clean so it is likely a low speed circuit in the Carbs that needs tuning and balancing.

Just had another listen to the Idle video and I concur the suspicion you have the low speed circuit loading it up and the timing at idle seems off too (based on the sound)

post-134876-14423701237979_thumb.jpg new manifold for the old girl, I ended up blowing it up, so instead of rebuilding it I'm going to do up a 202 to group nc specs because I want to turn the Orange lc in a group nc car car hopefully try and get around the 280 to 300hp mark

Thought I'd put these pics up for the old boys on here to reminisce on the old day, few years ago I pick up a old roller sports sedan lc/LJ torana, just because it looked awesome, well last night I found some pics of it back in it hey day racing, this is reaching back in 1980post-134876-14466011098864_thumb.jpgpost-134876-14466011243268_thumb.jpgpost-134876-14466011598339_thumb.jpgpost-134876-14466011695511_thumb.jpgpost-134876-14466011806746_thumb.jpg.

I haven't pulled it out of the car yet, but I'm pretty sure it's because the sump has no baffles in it , saving up for a ASR sump, , also doing a cash job on a vk and getting an accumulator setup off a xu1 for my motor. Should help it for next time

I picked up my sump today, I was told it was off a bianti series xu1 race car, I'm pretty happy with it.

    • You won't make it out of your driveway. Both your rear wheels will go in whichever direction they feel. Your Hicas rack or a lockout bar is required to keep your wheels straight. 
    • Updating results.  Using ATR45SS-0 model VS UHF57-900. Those two are very different turbos, different wheels sets with different wheel hub profiles but yet with almost identical result. I’m intrigued with both turbos performance. ATR45SS-0 was a 61mm turbo first developed in May 2020, UHF57-900 was a 62mm turbo developed in March 2024 as a powered up alternative of a G30-900. On paper ATR45SS-0 maxed at 563rwkws, while UHF57-900 maxed at 568rwkws. ATR45SS was slightly more responsive with slightly better power band through the mid range.  Road driving ability, ATR45SS-0 had better throttle response, felt more robust under throttle, as it wakes up earlier. I think G series wheel hub design made it to have higher inertia under light throttle. Doing bit more prototype work in the next few weeks, will update result when its back on dyno again. ATR45SS0 Blue, UHF57-900 Red Chequered tuner's Dynapack hub dyno, E85 fuel. Mod list is in video below video_20240604_114214.mp4    
    • Did you run the power cables for the mac valve to the other side of the car near the fusebox? Utilizing the stock boost controller cables? or did you run new ones?
    • Hey I have a potentially stupid HICAS question 🤣 I'm currently doing a full hicas delete, Power steering pump modified to non hicas, all lines removed from the car along with all electronics. My stupid question is - Do I need a lock out bar? is there any reason why I cant just remove everything from the rear end? I already have a lock out bar but thinking to save a few extra grams I could also get rid of the arms and tie rods as well and just run it with nothing in its place? or would it have a negative effect on handling?
    • Hi how are you guys?  I know i have been absent for years but im coming back slowly guys just wondering if anyone know where the ball joint on the NISMO arm front and rear can be replaced with OE parts?  Also  i know this is not the thread looking for springs and blistein shocks for the 260rs.
