P-PORT vs B-PORT vs STREET-PORT in a TURBO-13B

Let the debate (some consider argument) continue on here....
We posted enough off-topic material on Ralph's thread.

>>JD this is the last time i'll post to this thread and probably the forum as i've already said enough and should've just stayed out of it. You guys just want to argue all the time and i not going to get involved anymore.

I'm not going to build something to your specs.
Why the hell would i do that. I already know what works as i've already done it.
You seem to think you know what a pp motor wants have you done it before?
And not once did i say it's easy, i've been saying it possible and unless you guys have tried it don't say it isn't because of so and so.

I told you to bring whatever you got. I don't care what it is. As long as it's a 2 rotor i dont' care what you do to it.
I already have a pp motor here and i also have a dyno.
so if you want to prove me wrong the choice is yours...<<

-I am NOT arguing !!!...simply stating my opinion which I am entitled to.
Ok...those specs is what I have and obviously the debate is on ports and not on a alcohol fed PP-turbo 13B vs a pump-gas turbo street port 13B.

Since I can't bring a knife to gun fight and you already have a PP motor and dyno I could make arrangements on bringing a turbo sideport -13B and we'll run boost for boost till you say- enough !!!! or run out horsepower :-)

>We tested a pp motor and the more boost we feed it the more power it made.
Didn't seem to stop even at the higher boost levels. That is if you consider 52lbs high.<

-Do yourself a favor and post a dynosheet of this 52lb boost run to prove your point ! I'm quite sure the rest of the forum would love to see it as well.....
Or even any turbo PP-motor......

It might be a little tougth for you to compare notes, since making a P.P. engine is less streetable (usually makes a bridgeport's idle look friendly), and not to mention much more expensive. Although I am just stating the obvious.

Hopefully more non spam responses will come in.

I personally would like to see some more, I love P.Ports.

I like the idea, I was following the thread; and must admit that I think Enzo250 is right; but I don't know what I'm talking about, so if we can get some accurate data

BTW - Can we get rid of the post ******?

BETTER ??? if not, skip over my posts next time.

By the way, your last 4 posts on this topic were worthless to any of us therefore find something interesting related to the topic or take a hike!

I know what you're talking abt, but I think he was just trying to lighten things up. This could be a great discussion, though, and I hope he (crispeed) has more to add. In the relatively short time I've been in the game (only a year), I've gathered he's one of the more experienced fellas. I could be way wrong though!

Just having some fun. It's Christmas!
Don't let the keyboard gurus get to you. You and I bought been doing this **** too long to let that happen.
Anyhow I'll wait for more input befrore I reply.

Nah, you're not wrong at all....he's definetely one of the most experieced on this forum.

Can we generate a list of the Top 10 Most Powerful turbo-13B's (PP, BP or SP).
Chris, you could help us on this one.

Theres Been A Pp On A T78 Rx7 But I Never Haved Seen It Idle. Only On The Highway! This Would Help Out Alot For Us That Are Curious To Know The Results.

Imo Id Stay With A 1/2 Bp At Most For The Street. DONT KNOW IF I GOT OFF THE SUBJECT BUT THATS MY .2SENTS

Well I'm not an expert but this is the way I see it. Mazda has used PP's in their NA racing cars for years. Why, because a PP makes the most power in NA form. So if a PP makes the most power in NA form, why wouldn't it make the most power in boosted form? In a perfect world wouldn't you want the runners be as straight as possible to the engine with the very minimal amount of curves? PP's naturally allow this to happen over side ports since they don't have the 90 degree bend before the air flow inters the engine.

Since I shouldn't bring a knife to gun fight, arrangements could be made for a turbocharged streetport-13B on Methanol to demostrate its potential. If you even match his numbers it will be an accomplishment of its own !

Care to post a dyno sheet of this 52lbs run??
Or just post any (high-hp) turbo PP-13B dyno sheet.....I think the forum or myself has yet to see one.

Yes, no other port will come close to a PP as far hp.
Jesus and others have proven that by making over 350rwh from a 13B.
Volumetric Effiency (VE) can be over 100% with a P-port.

When you turbocharge a P-Port engine the overlap of both intake and exhaust port being open at the same causes some issues.
-Boost pressure to bleed off thru the exhaust side
-exhaust pressure to flow backwards into the intake when its higher then intake pressure.
-Exhaust and intake getting mixed into combustion chamber
-high fuel consuption ( no bid deal in race set ups)
-Further drop in thermal efficiency
-Poweband is moved up quite a bit....revving to 10Krpm+

If a turbocharged P-port is the key into making big hp #'s on the racing world how its not chosen by most racers ?
Abel for one....he made 968hp from his 13B with sideports and he had/has the funds to try PP....maybe he did try it !
He also has shown to have made the most hp out of his side-port-20B over the other PP-20Bs.....unfortunately not consistent.

We have street driven FDs almost breaking 700rwh with moderate boost(low 30's) and race gas... drop in some more injs, methanol and boost and 800+rwh is doable.
Ari ran street port all this time.....why didn't he try a P-port and make more power at less boost ?
Dee K...still running a street port....anyone wanna take a stab how much hp he puts down????

Quite sure there's more examples out there....

I would love to hear of 1000hp+ turbo P-Port 13Bs but we don't.
Maybe they're still on works as I keep hearing.....it's tough to get all those issues sorted out.

Good explanation JD. I guess the tuning difficulties far out weigh the "Possible"benefits that a turbo PP may have.

It's not necessarily a "tuning" problem/issue, more like the inherent properties of how a PP/BP motor make power with overlap, it works fine with a NA motor, but when you throw forced induction in the mix, it's a different story.

Best piece of advice to close out 2005

PP is best
BP is next best
SP is lowest
Stock port is gayest

NA
TURBOCHARGED
NITRO METHANE< NOS AND ROCKET FUEL PROPELLED WITH GM6/71 TWIN ROOTS BLOWERS INSTALLED PER SPARK PLUG !
*** IT MAKES NO FU(KING DIFFERENCE ***
0psi or 50+psi boost, porting & overlap increases = volumetric efficiency = power.
inexperienced people or magazine editors/writers etc + internet ****** need not comment on something they know nothing about.
