Injector size and turbo replacement question 3200gt

[Twinturbo]

Chap, I have no idea of relative levels of education or expertise. After 25 posts, however, I suggest that telling the moderators what they should do in what is regarded as one of *the* most successful, inclusive and knowledgable car forums out there is not a strategy likely to meet with success.

Just a thought, like, and I hope you are successful with your project.

LOL no I didn't mean it like that at all oops, they are the gods of knowledge and doing exceptional work on here without a doubt I meant to write it would concern me if I were a moderator ,I'll edit that sorry moderators

Amount of posts means I recently acquired my Maserati yes so a noob on posting on this forum and in owning a Maserati in general so love to learn but I have over 20 years experience working on and turbo tuning my own and others cars as an enthusiast and at a conversion tuning shop so I'm no rookie but I don't care what anyone thinks bout me I was Just trying to start what I now know obviously is a taboo conversation about the possibilities of the 3200gt

Right Bjorn, I have seen some guy on a FB group Keith who claims to run 500hp out of his Blue AC. Here was his post when I asked him how he got the 500hp.

"mainly it was putting on the bigger turbos. I think they were the same if not similar to the F40 turbo. Made by the same Japanese company for Ferrari. The cam was changed the oil coolers uprated it was a lot of work but worth it. It's a handful now. Feel free to come and view, drive, dyno test it whatever you want to do."

I hate to even post this I don't enjoy confrontation cause it's just not productive but it needs to be addressed
Thing that pisses me off is he's been a smart *** the whole thread bout this pressure issue but I've let it slide cause Everyone can have their say and I'm just like "hes a bit mistaken but I like everyone's input and he can have his rant I don't mind �� but then drops that whopper! And now trying to be smart to me ? enough is enough ok! you do not have a depth of education you think you do about turbo tuning ok it's just a fact so don't pretend to lecture or belittle me or others on here about anything to do with tuning in fact it makes me think what other rubbish you've spread on here to genuine people trying to gain actual factual helpful knowledge, Moderators might be concerned at what you've posted cause I don't care what personal attacks you have for me and I have no malice towards you but don't make others on here suffer from your misinformation!
Get educated before you post things as fact on here and for everyone's sake pull your head in!

I hope that wasn't directed at me!!

Yes you !! Jokes lol I wish this never turned nasty I just want this to turn back to what it was meant to be and that was an in depth conversation about prospects of tuning up the 3200gt , thanks Contigo do you have a link by any chance?
I'm almost certain I could tune this myself to 500hp but the negatives outweigh the positives ATM but I'm Getting a quote for a working engine replacement ATM so could change all that very quickly , and if I could revert my changes back to Oem that would be a bonus too so hence why a direct replacement high flow turbo would be great to find , the flanges seem pretty common being a ihi unit from the Subaru legacy so many larger internal wastegated turbos could potentially line up quite well

 

[mjheathcote]

Yes you ��!!

I think you need to re-read your own thread, I've only said parts are difficult to get hold of for the engine and agreed with you that Boomerang_GT was incorrect, and that bigger turbos generate more power!

1.1 Bar boost pressure will always be 1.1 Bar and will not result in any increase of power no matter which turbochargers you take.

/Confused!

I *think* he was joking, and the smileys got lost in the ether. I have a couple of question marks where I assumed there would be humourous emoticons

At the start of your post you quoted somebody who was agreeing with you and so tore into them (by inference). You were therefore lambasting the wrong person and it was somebody else entirely that you were disagreeing with. I agree with the advice to re-read the thread before posting and be a little more careful. We don't really do that kind of argument on this forum.

I'm sure everybody sincerely wishes you well with the project and you do seem to have all the credentials to make it work. Let us know how it goes and post some 'in progress' pictures.

Regards,
Steve.

3200 injectors stock 400cc .. i have 450cc . Bigger intercoolers and turbo dr.s oem tuned turbos, race cats on straightpipes
600 on wheels !! More to come...

At 1.1 Bar boost the engine takes 1.1 Bar into the cylinders regarding to the revs. It does not matter what is at the other end that delivers the boost. If the mapping is set to 1.1 bar it will deliver 1.1 Bar. A bigger turbo will have a bigger lag but will not result in more HP. That's a fact that LOL-boy will have to live with or leave the engine mods to someone that has knowledge. Reduce compression ratio and increase boost = more hp.

Unless your taking the **** just saying that cause it's exactly what I'm after and first post ....but for my knowledge and to help the community are you able to provide technical specifics I have a million questions
✍

Which injectors? Were they drop in or modified rails? Fuel regulators?
What turbos are they? Got a web site of them? Are they Direct fit to stock manifold and exhaust or custom?
Intercoolers? Are they just a thicker cooler in Oem location?
If any what engine work did you do and tuning ? Yours a manual or auto?

Many thanks if this is a genuine post

And here we go again....
So in your magical slightly dull world of physics fuel tuning,intercooling,exhaust scavenging,cams,intake flow,nitrous oxide power and turbo cfm don't exist?

I wonder how the tuning shops do it then for example you got multiple 1000rwhp plus twin turbo supras out there stock is 12psi at 200rwhp they are not running 60psi not even close only 25-35psi most times and no added nitrous
I know your not into tuning cars but you really need to go to a turbo tuning shop so they can help you understand how horsepower is made and again just cause you think your right it's not fact it's actually ridiculously false

It's quite possible to make more power with not much more boost in terms of PSI/BAR.

It's all about the air volume, not just pressure.

A bigger turbo at lower psi still can produce more air per cubic inch than a small turbo at higher psi.

The air may be getting pushed harder by the smaller turbo but there is more air getting pushed by the bigger turbo.

Obviously there still remain the considerations about lag, and efficiency etc.

When sizing up turbos you have to looks at compressor maps and plot on the graph where you think your engine is in Volumetric efficiency and many other factors.

I spent ages doing this for my Urquattro, but there are a few online tools to help.

One of the best things I did was to have the head ported, that way VE improved and I made more power and at lower boost pressure, a much more drivable engine.

Exactly, nicely explained.

MJ just to clear things up my previous Controversial post was certainly not directed at you I welcome any feedback but not false and condescending ones that were comming from another member on here, I quoted your post cause I agreed with it not for any other reason
