What a journey it’s been. Yesterday, 4 years and 362 days since the terminal engine failure of my EPR “built” VG30DETT, my Z was back on the dyno.
I’m happy to report the engine that I specced, prepped and assembled survived and took everything that was thrown at it, with oil pressure being reported as “fantastic”. For a “hobbyist” I should be proud.
But I didn’t get the dump of dopamine I was expecting at the conclusion of the day, that rush of “I did it”. Instead I got the cold sweat of dread when Romain of RaceCal Ltd came off the dyno to debrief me. Fundamentally, everything is fine and the Z has a solid tune, but not without issue…. and I think it’s that very BUT that has taken the sheen off was a good day.
Firstly, the engine has a fuelling imbalance between banks that shifts dependant on load. I have a vague recollection that I’ve had this problem before and never got to the bottom of it.
That in combination with an issue with one of the hub dyno’s having a peculiar loading issue, brought about the conclusion of the day in the interests of safety. And I’m completely content with that decision!
A few other minor issues including a small oil leak that needs to be found as well as the curse of the ATi damper PS belt issue, meaning a 85 mile drive home with no PS.
I think the final factor in my overall post dyno emotions are that I thought i had everything in place to get the optimum output for this setup….. and I don’t. I need to invest time in making proper intercooler ducting to get that IAT recovery and efficiency to be able to make back to back runs. I need to add a second fuel pump to give me more head room to allow the potential maximise the 2860 turbos. I need to find the cause of this imbalance to remove any risk of misfuelling so that tune can be absolutely bang on to really optimise this setup. So, the journey isn’t over yet….. more work, more learning, more money 😂😂😂.
Just a quick one to say thanks. Thanks to Romain of RaceCal Ltd for his time, for his ability to recognise my level of understanding and communicate to me where I can solve issues and make improvements. I look forward to working with you again! #vg30dett #z32 #300zx

This bloke with Tourette's Syndrome walks into the most exclusive
restaurant in town.
'Where's the pissing, motherfucking manager, you cocksucking
arsewipe?' he inquires of one of the waiters.
The waiter is taken-aback and replies, 'Excuse me sir but could you
please refrain from using that sort of language in here. I will get the
manager as soon as I can'.
The manager comes over and the bloke asks, 'Are you the chicken-fucking
manager of this bastard place?'
'Yes sir, I am,' replies the manager, 'but I would prefer it if you
could refrain from speaking such profanities in this, a private restaurant'
'Fuck off' replies the bloke 'and where's the fucking piano?'
'Pardon?' says the manager.
'Fucking deaf as well, are we? You snivelling little piece of shit,
show me your cunting piano.'
'Ah,' replies the manager, 'you've come about the pianist job' and
shows the bloke to the piano.
'Can you play any blues?'
'Of course I fucking can,' and the bloke proceeds to play the most
inspiring and beautiful sounding honky-tonk blues that the manager has ever
heard.
'That's superb. What's it called?'
'I tried to shag yer missus on the sofa but the springs kept hurting my
dick,' replies the bloke.
The manager is a bit disturbed and asks if the bloke knows any jazz.
The bloke proceeds, playing the most melancholy jazz solo the manager
has ever heard.
'Magnificent,' cries the manager, 'What's it called?'
'I Wanted a wank over the washing machine but I got my balls caught in
the soap drawer'.
The manager is a tad embarrassed and asks if he knows any romantic
ballads.
The bloke then plays the most heartbreaking melody the manager has
ever heard, 'And what's this called?' asks the manager.
'As I fuck you under the stars with the moonlight shining off your
hairy ring-piece,' replies the bloke.
The manager is highly upset by the bloke's language but offers him the job
on condition that he doesn't introduce any of his songs or talk to any of
the customers.
This arrangement works well for a couple of months until one night,
sitting opposite him, is the most gorgeous blonde he has ever laid his eyes on.
She's wearing an almost see through dress, her breasts are almost falling
out the top of her black lace bra,and the skimpy little 'G' string she's
wearing is doing very little to conceal her ample charms.
She's sitting there with her legs slightly open, sucking suggestively on
asparagus shoots as the butter is dripping down her chin.
The image is too much for the bloke and he scurries off to the Gents to
furiously masturbate. He's tugging away furiously when he hears the manager's voice.
'Where's that bastard pianist?'
He just has time to relieve himself, and in a fluster he runs back to
the piano having not bothered to adjust himself properly, sits down and
starts playing some more tunes. The blonde steps up and walks over to the
piano, leans over and whispers in his ear, 'Do you know your knob and
bollocks are hanging out your trousers and dripping spunk on your shoes?'
'Know it' he said, 'Hell I wrote it.'
CheerZ,
Andy
