PP 13B Turbo
I know there are a few of these projects underway, but I'm wondering if anyone has some pics and hopefully video of a completed engine. Also I'm stuck on designing the intake manifold so if anyone can help with that I'd appreciate it alot. Thanks everyone.

we're already talking, but im sure people have some good ideas on here.
|
I guess outside of zander and myself there really isn't any interest in a P-Port turbo 13B. I figured that you race guys would be all over this.
|
theres Deslow as well, dont forget he has his build in the fabrication section.
|
dude there are a lot of PP turbo....lots in puerto rico run in the 6 sec....
remember that you timing and such will be crucial..I am not sure how it is set up since i have been mostly PP NA myself............. if you decide to run a TB style IDA then mani is easy..just make a plenum style box to encase TB and run to turbo....you can almost copy a blown through carb set up i would think... just my 2 cents |
I've seen some interesting designs for P-port intake plenum. i wonder how air intake to each rotor is effected due to the difference in the distance between the runners? I would imagine that this would be a bigger issue on something with a 20B more so that a 13B , but it would also effect the design of the intake as well correct?

plenums are more prevelant in turbo apps....but design will affect torque/hp range of course
most important thing to remember is overlap is fantastic for NA apps, but on turbo will affect your range of power....maybe a bigger turbo is better for this application..? not too sure about this... |
this is a 13pp turbo using xtreme rotaries pp inlet kit... theres heaps of videos of that car

I like it

A couple of guys over here run PP Turbos and semi PP, here is a pic of a 13B PP running a T51R with a 1.00 AR housing. remember AR is the ratio revalant to the Turbine wheel not a distance measurement. He has run a 10.7 at 0.8 BAR on a shakedown run so far. |

Have you built any PP turbo engines dude, or do you just like to chat on here :lol:.?
Do you have any more pics or any videos of that car? |

Lots of pports running in the 6 seconds? There's not alot of any rotaries running in the 6 seconds let alone pports. You can count them on one hand.

Not only that, but out of all of the PP + Turbo engine setup, the only one that is still using that combination is "El Duke". All of the other ones, switch back to the non PP setup.

it seems to me that alot of guys are running PP or Semi PP in both Austraila and Puerto Rico, I may be wrong on alot...
but from what I can tell there are still a few....let me ask this then....are guys going away due to the use of turbos which dont really like overlap? or are they seeing just as much power from a bridge? It seems to me that since a PP NA makes more power per cc than a bridge or SP that it would be equally true for a turboed PP...of course I havent taken into considertion overlap.... but making all things equal..ie turbo size boost and injectors etc. would the PP be more HP anyway? again this is my opinion...i may very well be wrong..it wont be my first time...my whole life unitll now was dedicated to building PP NA race cars....just now tinkering with any turbo stuff |
well, there is a 13bppt that layed down over 1300rwhp, so that should answer any questions about power potential; over 1000 hp per liter.
|
right......that makes sense to me...hmm but what do i know..lol
|
check out grs-motorsports.com thers alot in the 7s i would say not so sure about the 6s. theres alot of fast puerto rican cars here.

well, most of them are running semi-pp.

El Duke wasn't looking to good at Pan Am. :P

I will be running a GT4202R with a 1.0 Tial housing..

^^^^^^ 13 bt stock? i doubt it...maybe Big bridge D which in therory is basically closse to PP in terms of overlap
I am thinking that a PP can and has and will make goobs of HP ....even if it is at higher rpm.. it means a stronger shaft set up and some tweaks but why not do it.... i have had a NA PP run 11000rpm with out any damage or turned bearings....on a stock shaft now that may be a fluke but i have also run NA PP 10500rpm all day in caribbean heat waves and they last all season long If i can have that durablity on stock internals..(minus carbon seals) a dont see a PPT being any worse Of course durablity is only one variable....there is tuning and timing etc. which again with a good after market ecu is doable..... as rpm goes up airflow becomes so violent that overlap should be the least of the issues....( just like with valves..how much closed is a valve VS open at higher rpm? neither really its just as open as it is closed...vurtual float..) as long as a turbo can sustain air flow pumpablity the engine will continue to make power..also VE must be sustained to ensure engine efficiency......all of this will either make it work great or loss power but this is also true with any port config....not so? |
