I'm going to build a single throttlebody plenum intake so I'm selling my current intake manifold with the ITBs. Buy it!!



62mm throttlebodies, runners tapered to 50.8mm at flanges. V-band flange to your port runners (2.25" clamps not included). Includes TPS, MAP sensor, 4 fuel injectors in throttlebodies (approx. 550cc), filters, -6AN fuel rails to fit MSD / Holley / Rochester fuel injectors. Basically everything pictured except green and black MSD fuel injectors visible in picture (4 required).



If you have peripheral port 13b motor add v-band flanges to your runners, pick up some clamps and fuel injectors and away you go. This setup idled at 1000RPM on my motor with 720cc primary injectors. Primary fuel rail has an extra -6 fitting to feed nitrous system.

Did you ever dyno your setup?... My original setup was much like that , the long runner makes a nice flat torque curve, my peak was basically unchanged from 4500 to 9500...

I dont think you will be happy with a single throttle on a peripheral port, High overlap and combined ports from different rotors doesnt work well,especially for a street car, since the vacuum from one rotor causes more charge dilution and reversion in the other chamber. Hence the reason an ITB p-port will idle better than even a half bridged stock manifolded motor.

I have a new intake assembly now together, with multistage taper, right down to the GT p-port intake lengths which should boost my rwhp over the old setup..

The p-port still had more low end than any other n/a I encountered.. The noise is difficult to deal with, but worth it.

 

Motor died on the dyno due to what looks like some kind of oil system failure, oil was full of copper and all the bearings failed.



I'm doing the single throttlebody so it will be easier to add a turbo later, plus NDRA bans ITBs in the Sportsman classes.

 

Drag is your goal? Sorry to hear about the motor..

To bad about the rules, a friend of mine has already been down the turbo p-port throttle body road, and the ITB's worked alot better...

What kind of oil pressure did you have on it, what kinda revs was it at when it croaked?... I have bounced off 10k with largely a stock s5 internal motor, so far ok..

I was at 206 rwhp on a mustand dyno through full exhaust originally, but had lots of vacuum at WOT at high rpms, so I knew my intake was strangling the motor..Hopefully thats solved now..

Good luck with the sale..

 

I hit 10K too and drove it a lot after, it was crazy lean on the dyno when it died so I expected a seal failure.



Took it apart and all the bearings were totally ruined, the rotor bearings fell out on the floor even. It had always had good oil pressure until after it failed but still ran, the oil pressure was bouncing up and down then. Rotors touched the plates, but that might be because the bearings were wrecked?



I keep seeing these AUS and NZ turbo three rotors with a single throttle body and they seem to idle well anyway, so I thought I'd try it. Setup will be simplified anyway.





Intake is sold and delivered BTW.

 

Wow, wish I had seen this earlier.

How much did it sell for if you don't mind me asking?

 

300 bucks. I think I should have asked for more maybe, I had 1 serious inquiry, 2 serious offers and one dumbass, all locally, all in 24 hours.

 

I would have gladly sent $300+ your way for that

 

Should I put you on the list for the next design if it works well then?

 

Well, as long as you fab something I can either use on a 12a full pp or 13b partial pp.

Also you have to design something before I feel comfortable enough to design something myself with my Miller Syncrowave 180sd.

I'm really impressed with what I've seen though!
