btw, Feral and I saw eye to eye on horsepower potential of the A series. eg:

The relevance of peak torque to the discussion is obviously over your head. EFI doesn't increase peak torque, specific torque, or peak power. So explain how it wil make a useful difference in a race engine with 162hp @ 9100RPM, 96 lb-ft @ 8300RPM. Quote:
specific torque values - google it. As explained before that is what has the alarm bells ringing with their claim of making more power at significantly lower rpm. Also BMEP while you're at it. The parts you think sound arrogant and superior are simply me paraphrasing your words from your 1800cc A series build thread telling you not to question it here and go and do your own search! Quote:
I think you mean realisism about power potential of the A series. Things like Vixen and co claiming 200bhp A15 in their Datto 1000 that couldn't out drag or out perform cars with no more than 3/4 that power and hundreds of kilos heavier, or those bullshit claims of 10,000rpm Dattos down Conrod from the old days, 200bhp A13 TS Cup engines (pretty obvious where that mis-information came from)etc... And once again, the only control freak stuff in this thread is where I paraphrase, or directly quote you from your A series build thread.

D, always the first with the low blows.
C'mon take it elsewhere.

""Until it has been done, it is nothing but dreamers' imaginary adoration & nonsense. BTW PitRoad are still building those engines to this day. But you know better than the guys who have been building them continously for 40yrs, sitting there at your keyboard telling everybody how to make more power and "improve the area under the curve""
Like you are the authority to judge? only you Harry c'mon you angry sad creature stop putting words into my mouth, everyone knows that if they used todays latest technology they would make more hp but they do what they do for Heritage reasons which is evident to even a fool. Now if they chose to use the latest tech avail because thats what Japanese datsun perfectionist afficionados and datsun adoring fans want to reproduce, the exact specs of their heyday heros for nostalgic reasons. efi does makes more torque under the curve, I said nothing about peak and specifically about efi only still dont you get that yet, the combination of todays technology will amount the overall hp increase. The "peak only hp" achieved by efi vs carb debate is in your mind only you re-read what I said. There are many variables and possibilities in an engine build and fuel that we have no info on, and if you think its avail about this topic on the net, post the information that is not laughable and prove it dont just say its dubious because you think you know better, prove it and stop thinking you are superior to everyone here by just knocking back anything. Not just your thread but other peoples threads you have your negativity and control freak nature which has been a bore for quite some time. There were some time back plenty of other credible posters on this forums but your bitchy attitude drove many away.

which is another way of agreeing that it won't make any more peak power. These things are operating with peak torque and peak power as close as 800rpm apart FFS eg Pitroad's 162hp @ 9100RPM, 96 lb-ft @ 8300RPM - they are already optimising the area under the curve for peak power. That couldn't be more clear. EFI doesn't improve peak torque either btw. That's another well established principle, nothing to argue about or question. Quote:
read what I said, and then go and reasearch the priciples you don't understand. Specific torque is a well established measure, and the notion you have that it is possible to get damn near 20% gain in specific torque over those other examples is simply laughable. There is a wealth of information on the subject available to you on the net, there is no need to question it here in this thread. PLEASE keep opinions and hijacking out of here and do some research to see that this is not possible rather than filling up the thread with white noise.

Yes the thread is "Nissan Heritage Collection - Sunny TS Cup specs" which also means 30 year old tech that makes many wonder not just myself but as Feral did also in a conversation, what could have been if the A series was continuously developed without restrictions. Its no dream just adoration.
As for my threads, I dont mind peeps posting something to help with the elusive workings of Mazda headed A series but I didnt want a newb asking can you use the ca18de rods, or can you sleeve an A series, or just use the whole Mazda engine as you have put on the other thread on the Mazda headed A series. You just cant accept that some people think differently and are driven by different goals. Also I am not comparing carbed to efi "alone" that is your tunnel vision interpretation once again. Yet by now Im not surprised you cant accept that an A series with todays tech cannot make more hp compared to what was done 30 years ago. I had this conversation with Feral on the same subject of the Sunny TS Cup cars, nothing off subject just adoration again for the Marque and general interest. He believed it was possible. On the carb vs efi you just stated, a carb no matter the size cannot match the fuel delivery/accuracy of todays efi which makes more torque under the curve definitely way more important than max hp. The dubious figure you labelled A12grunt for the 170hp at 8000rpm he posted, Do you know if its a later incarnation eg. an improved later build where they found some extra power with improved flow, pistons and or combustion chamber design or even a sprint build/tune for shorter tracks just for getting pole position? or is it a misprint or error? Did they use the same dyno? different fuel for that year/race/series/sponsor leaving more room for higher compression? why not just say its a confusing figure just in case or do you have concrete information to disprove it?

No, the thread title is "Nissan Heritage Collection - Sunny TS Cup specs". You just bomb the thread with yet another imaginary/hypothetical A series dream, while insisting people stay strictly on topic in your threads and not even dare to question anything you say...
I think Nissan Motor Company's Heritage Collection is a credible source. The article on Pit Road’s Takakazu Sano and the cars/engines he builds also seem credible based on the specific torque of thier claims being within the realms of other full race 2v engines over the ages. Feral is also entirely credible, and he hasn't disagreed. The figures you remember him stating are entirely consistent with these examples, so I'm not sure what you're on about there. EFI won't make any more peak power than a carb btw. And those 44mm Solex and 48mm Webbers will both comfortably flow more power than the respective engines are making, so they are not a limiting factor. Anyway, please keep it on topic. If you want to talk about isotropically finished, friction coated, EFI A12's start another thread.

yawn, is that the title a realistic A series horsepower thread? it doesnt say that anywhere or make you the authority on what is credible. Entities like anyone often overquoted their figures in more than race engines.
All the examples where all carbed, so some can naturally wonder no crime there. Feral was more credible than anyone still here on this forum.

sigh. So much for having a realistic A series horsepower thread...
real world examples of the best full race A series engines from credible sources and people still want to imagine how much more they could make 'if only'...
