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

The 3 strongest urges in humans are; Food, Sleep, Sex. IN THAT ORDER. You
can survive without sex but the species can't. You can go without sleep for
a while but you eventually go mad. You can only go without food for a short
while. If you only had food, you would sleep before having sex if you hadn't
slept for a while. If you have food and sleep, you seek sex. Evolution made
us that way so that we survive. It's all about PRIORTIES.
A man's biological strategy in life as far as sex is concerned is to have
sex with as many attractive women as he can. [because a man can father
hundreds of children]. He needs to be receptive to a woman's acceptance; he
takes the best he gets offered.
A woman's biological strategy in life as far as sex is concerned is to get
it from the best man they can get. [because a woman can only have ~one baby
at a time]. She needs to get the best genes she can.

This is why men seek sex more keenly than women IN GENERAL and are less
fussy - there are exceptions as there is always variation in nature.
But the attitude today is largely that men should be faithful to one woman
at a time. This means the man is compromising himself, while the woman gets
her way. She may secretly be on the lookout for a better man, but if she did
find one and leaves the first guy, she has done nothing wrong. Yet if the
man plays away from home he's a bastard !
Monogamy suits women more than it does men.
WOMEN ARE HAVING IT THEIR WAY THE WAY MEN USED TO HAVE IT THEIRS !!
It's time men stood up for their rights, but how's that gonna happen ?!!
They'll just be frightened of not getting any from their women !!
By the balls ? Well and truly.
