Yeah but that guy said alot of stuff.

I don't know if he posts around here, but IIRC there was a guy named Rob in Japan (sokudo) with a turboed full bridge in an FD. I think he was using a T51R Kai? Maybe a google search on that sokudo name would bring up something....

His site is www.jouleusa.com and last I heard he was making 655 rwhp @ 25psi with the HKS T51 kai.

Alf (Soul Assassin) was making 620 rwhp @ 22 psi with a very similar setup (full BP, t51) on a red FC he used to drive.

What I do to those cars = https://www.nopistons.com/forums/pub...1047683894.gif



There's videos of their cars floating around the RX-7 Club. The sound... wow! I need to find that video of Sokudo's showing a closeup of his turbo inlet while reving the engine https://www.nopistons.com/forums/pub...IR#>/boink.gif

The same way it works on a streetported engine, a stock engine, or any engine for that matter.

HAHA ...... dick there is alot more to think about as in overlap and cracking a bridge . im sorry but there is ALOT more to think about than when just using "a streetported engine, a stock engine, or any engine"

Now now, no need for name calling.

And of course there are other factors to consider, but that wasn't your question. You asked how a turbo would work on that type of engine, so I told you how.

So....?

Soul Assassin had a full BP with a t51, I think he is going to be building another RX7, unless the thread on the "other" forum was a joke.

sorry about that it just seemed like every one was jumping on my back when ever i post, but i also misread alot https://www.nopistons.com/forums/pub...#>/biggrin.png sorry for the name calling. What are the pros and cons of a full bridge turbo ?





David

Advantages:

- awe inspiring power potential (up to around 950-1000 bhp)\

- faster turbo spool up (compared to 1/2 BP or Streetport on same setup)

- coolest sounding engine in town

- awe inspiring power!



Disadvantages:

- less "off-boost" power vs streetport

- more fuel consumption

- shorter lifespan and less reliable

- LOUD (some may argue that they like loud cars, but they are the ones who have not heard a bridgeported rotary with open exhaust before!)

- to make serious power you need to rev that much higher, so more wear and tear on components which need to be upgraded to allow this operation



I'm actually going to be building a full bridgeport S5 engine this fall. I'm planning a 9,500 redline, 20 psi max boost and looking for about 1 bar at or before 4,000 rpm. Not totally set on which turbocharger and size right now, but it seems to be coming down to the T66, T51 kai, TA45, GT40, GT42.

Any suggestions?

a buddy of mine had a full bp rx3 (na) and here are the differences vs a stock port.



pros:

more torque from 2000-11,000rpm

sounds neat

25+ mpg on the freeway



cons:

does not do part throttle under 5000rpm

when you cut the water jacket engine life goes way down (12-18months, before it starts sucking water)





the car was NOT loud, it was using 2 loooong glas packs and 2 turbo mufflers, it was very reasonable
